PHP Wordpress optimization my loop code
I'm just learning PHP, and I'm using get_terms to get some text descriptions from the CMS, but i want to assign 3 variables to only 3 of my woocommerce tags. My code works well, but I just want to learn if there's a better way to filter by $tag_descrip->name than using if conditions.
This is my code:
<?php
$tag_descrip = get_terms( 'product_tag', 'orderby=count&hide_empty=0' );
$count = count($tag_descrip);
if ( $count > 0 ){
foreach ( $tag_descrip as $tag_descrip ) {
if($tag_descrip->name == "parfum_bestof")
{$title_new1 = $tag_descrip->description ;}
if($tag_descrip->name == "tshirt_bestof")
{$title_new2 = $tag_descrip->description ;}
if($tag_descrip->name == "child_bestof")
{$title_new3 = $tag_descrip->description ;}
}
}
?>
Thanks | Hi there is not better option, but to speed it up little you can use wordpress transient, see documentation: <
your code would look like this (and i cleaned it bit and used function empty to check array...):
<?php
if ( false === ( $tag_descrip = get_transient( 'tag_descrip' ) ) ) {
$tag_descrip = get_terms( 'product_tag', 'orderby=count&hide_empty=0' );
set_transient( 'tag_descrip ', $tag_descrip );
}
if ( !empty($tag_descrip) ){
foreach ( $tag_descrip as $tag_descrip ) {
if($tag_descrip->name == "parfum_bestof")
$title_new1 = $tag_descrip->description;
if($tag_descrip->name == "tshirt_bestof")
$title_new2 = $tag_descrip->description;
if($tag_descrip->name == "child_bestof")
$title_new3 = $tag_descrip->description;
}

Javascript included but alert() function not working
I've included the javascript by
wp_enqueue_script('slider', plugins_url( 'slider.js', __FILE__ ) );
with just a simple
$(document).ready(function () {
alert("alert");
});
It shows up in the browser but doesn't prompt me with "alert".
PS: Forgot to mention I've also included the jquery, but still not working.
wp_deregister_script('jquery');
wp_register_script('jquery', "http" . ($_SERVER['SERVER_PORT'] == 443 ? "s" : "") . "://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js", false, null);
wp_enqueue_script('jquery');

In addition to the answers, I also had to tell wordpress that my script depends on jQuery
wp_enqueue_script( 'slider', plugins_url( 'slider.js', __FILE__ ),array('jquery') ); | A few things:
1. The version of jQuery that ships with WordPress is run in noConflict() mode. Meaning you have to use `jQuery` instead of `$` when you make your first reference.
2. Don't register your own version of jQuery when you're developing. You're locking yourself in to a single version that may or may not be compatible with WordPress' other requirements.
3. You can use the browser console to test things. Open your page, then hit F12 to launch the console. Type `jQuery` into the console and see whether or not it returns the correct object. | stackexchange-wordpress | {

I have no images in an activated wp theme
With this line everything works fine - (as a **Non-Wordpress** index.php):
<link href="style.css" rel="stylesheet" type="text/css"/>
When I activate the file as a wp theme and replace above line with:
<link href="<?php bloginfo('stylesheet_url');?>" rel="stylesheet" type="text/css"/>
everything is ok, except - there are no images.
For example - a div with an image:
<div id="about">
<img id="thinker01" src="images/thinker01.png" width="120" height="163" />
</div>
**images** folder is inside theme's folder. | > images folder is inside theme's folder.
But relative URLs do not work that way. They are relative to the URL not to the filesystem path. Your problem is here:
`<img id="thinker01" src="images/thinker01.png" width="120" height="163" />`
If you look at the request (via HttpFox or other means) you will see that the browser is looking for the image at ` and not at ` Don't use relative URLs like that. Give it a complete path as you did with your stylesheet. | stackexchange-wordpress | {

alphabetically order role drop-down selection in dashboard

Is there any way to do this? | Almost the same approach _One Trick Pony_ has chosen, but I am using translated names and `uasort()` (to preserve the keys):

* @wp-hook editable_roles
* @param array $roles
* @return array

function t5_sort_editable_roles( $roles )
{
uasort( $roles, 't5_uasort_editable_roles' );
return $roles;
}
/**
* Compare translated role names.
*
* @param array $a First role
* @param array $b Second role
* @return number
*/
function t5_uasort_editable_roles( $a, $b )
{
return strcasecmp(
translate_user_role( $a['name'] ),
translate_user_role( $b['name'] )

How is WP Cron Locking implemented?
WordPress takes measures to ensure that a cron task doesn't run twice when it should run once, e.g. once every hour when an hourly schedule is given, rather than the occasional twice at the scheduled time.

Get 1st parent category id from post
I have this structure for my categories:
Issue 4
- News
- Supporting our troops
- Breaking news
<?php
$category = get_the_category();
$parent = $category[0]->term_id;
?>
This code gets the top level category ID from "Breaking News" which is Issue 4, missing out News its direct parent category.
How could I get the category ID for "News", its direct parent category and not the top level category? | You need to use `get_ancestors()`.
Assuming your post is only in one category, the following code should work (if it's in multiple you'll need to loop through each of the assigned categories to determine the various hierarchies).
$category = get_the_category();
$ancestors = get_ancestors( $category[0]->term_id, 'category' );
$direct_parent_id = $ancestors[0];
If you want to get the entire category hierarchy as an ordered array of IDs (which I like to have available) you'd do:
$category = get_the_category();
$hierarchy = array_reverse( get_ancestors( $category[0]->term_id, 'category' ) );

WP_Query meta compare must include ALL array values
I am allowing users to query posts using a form with checkboxes. I want the posts to be filtered by the checkboxes but instead of showing all posts that include the ANY of the meta values selected I want to show posts that contain all of the selected values. Is this possible? Here is what I currently have using the "IN" operator which just checks if the post contains any single value in the array.
$the_query = new WP_Query(array(
'post_type' => 'listing',
'posts_per_page' => -1,
'post_status' => 'publish',
'category_name' => 'private_rental',
'orderby' => 'rand',
'meta_query' => array(
'key' => 'row_amenities',
'value' => $amenities,
'compare' => 'IN'
)
)); | You can have multiple `meta_query` arguments with the same key and that will produce the results you're seeking. Here's an example:
$meta_query = array_map( create_function( '$a', 'return array("key" => "row_amenities", "value" => $a);' ), $amenities );
$the_query = new WP_Query(array(

'posts_per_page' => -1,
'post_status' => 'publish',
'category_name' => 'private_rental',
'orderby' => 'rand',
'meta_query' => $meta_query

Show posts in category x and y from the 6th most recent post onwards
I'm struggling with the query for this in WordPress to display posts in a category from the 6th most recent onwards.
Basically, I have a top 5 posts section at the top of a category for featured posts (marked as posts in that specific category AND in a Featured category), then in the page content I don't want any of those top 5 featured posts shown in the regular posts loop.

Will adding & modifying default Wordpress table index break future Wordpress update

I'm wondering will adding these indexes break future Wordpress update when they choose to add index to the same column? | Adding a `BTREE` or `HASH` index shouldn't break anything, and I imagine that is what you want. At worst you could end up with multiple indexes, or less than optimal ones, which might negatively effect performance.

How to activate/deactivate menu tab and keep the same id?

If you don't see the option, click screen options in top-right, then check the option for CSS classes. Then you can write all the CSS on this class instead of the ID.
For all other options, you'll go in your theme & use a custom walker for your menu. If the id remains constant, you can add or ignore the particular item from being displayed depending on some condition.

Changing the wp-config.php broke the site
I added the lines `define( 'WP_CONTENT_DIR', $_SERVER['DOCUMENT_ROOT'] .

I immediately removed the above lines from the `wp-config.php` however that did not change anything.
PLEASE HELP | There're some things you should _not_ play around with, until you really know core inside out and one of those things are the Path constants that _can_ be set in your `wp-config.php`.

# define( 'WP_CONTENT_DIR_NAME', 'wp-content' );
# define( 'WP_CONTENT_DIR', ABSPATH.WP_CONTENT_DIR_NAME );
# define( 'WP_CONTENT_URL', WP_SITEURL.WP_CONTENT_DIR_NAME );
There're dozens of things you shouldn't touch in there, but Path constants and the Proxy settings are those that can get broken most easily.

Allow multiple contributors to one post
I have been asked how easy it would be to have multiple contributors being able to submit content that would be brought into one post.
The rub is that they wouldn't be allowed to see the main post or edit the post, this would be reserved for the site admins - their role would be mainly around adding their piece of the post into the mix and that would be it.
I know this isn't standard functionality, but I don't even know where I would begin looking for a plugin - I could roll my own but if this is a solved problem then I would rather utilise that fact. So I guess my main question is _Is this a common power-user feature and what name does it go by?_
This is essentially to replace the current system that involves people emailing in content that gets copied and pasted into the post. | Perhaps you could use scribu's Posts 2 Posts plugin to relate a Custom Post Type called "Drafts" (or something else to avoid possible conflict with naming conventions reserved for Post Status).

wordpress multisite domain mapping redirects to original subdomain
This week I installed Wordpress 3.4.2 (Linux Centos + Apache2) and configured the network option using subdomains.

Why does WP recommend against custom favicon functionality in themes?

> If implemented, favicon functionality is required to be opt-in, and disabled by default.
> If implemented, favicon functionality is required to support user-defined favicon images | Probably because a thing like a favicon is not necessarily tied to the on-page design, but to the branding of a site in general.
In other words: it's not specifically part of the "display" of the site. If a theme does choose to implemented it, an ender user might not want it (opt-in only) or they may want to use their own favicon (user-defined) to fit with their branding. | stackexchange-wordpress | {

How To Export/Import WordPress (MySQL) Database Properly Via Command-Line?
Normally, a MySQL database can be exported and imported using these simple SSH commands:
**Export:**
mysqldump -u USERNAME -p DATABASE_NAME > filename.sql
**Import:**
mysql -u USERNAME -p DATABASE_NAME < filename.sql
But it's not that simple when it comes to WordPress. From what I see, additional parameters need to mentioned, such as `--add-drop-table` for instance.
The WordPress Codex does provide some info, but it looks cluttered and not clear enough.
It would be great if someone who uses command-line can share the proper commands to export and import a WordPress database, with some explanation (of any new parameters used).
Also, are there any reasons why it wouldn't be advisable to use command-line when dealing with database, and instead go with a GUI like phpMyAdmin? | It is that simple for Wordpress too. I use the following to back up my WP sites:
mysqldump -u <user> -p<pass> --quick --extended-insert <db-name> > backup.sql
The mysqldump document gives the details on all the parameters.
`--extended-insert` is quicker when updating a DB from a dump file and makes the dump file smaller.
`--quick` makes the creation of the dump quicker.
You don't really need to use either of those, just makes things a bit quicker and writing an insert for each row just makes me feel happier - your original dump syntax would be just fine.
Don't forget though that there is domain-specific entries in the DB so if you are using this method to backup/restore then you are fine but if you want to move from one.com to two.com then you will need to edit entries in `wp_options` after you restore your dump. | stackexchange-wordpress | {

Is the part "category" fixed to an URL to an archive or post?
I'm asked to set up a WordPress-based site, which is not intended to run as blog mainly but anyway we want to use the common article area sometimes. Now my client resents that the URL to an article or archive includes "/category/". He wants to make use of tags but categories are redundant since he only wants to have an area called "news" which holds all stuff written as common articles. So my question is: Can I set my theme to simply make URLs like this: "example.com/news/an-article-about-something"? | By default, the URL to an article does not include "category". Only URLs to category archives do, so it sounds like something has already been re-configured.
Anyway, to get the string you want, go to wp-admin->Settings->Permalinks and set the permalink structure to "/news/%postname%/". That will put the blog posts at "/news/"
If you also want the blog index at "/news/", create a page named "news" then go to wp-admin->Settings->Reading, click "static page" and set the "posts page" to "news". You will need to set the static front page to some other page or you will get a blog index there too-- same thing in both places.
The same "Permalinks" settings page will let you change the "category" and "tag" strings, which show upin category and tag archive URLs. Look down at the bottom. | stackexchange-wordpress | {

How to direct user to actual 404 page when a check is false in single.php?
Can someone tell me how to direct a user to the main 404 file instead of having to print an error message saying "file not found" in single.php?
For example:
<?php
if (!$myVar) {
// go to 404.php and return an official file not found header
} else {
// show the following HTML
}
?> | You can use the `locate_template()` function to include the 404 template. Remember to do this instead of using `get_header()` or generating any output; otherwise you will have a duplicate.
<?php
if ( ! $myVar ) {
status_header(404);
global $wp_query;
$wp_query->is_404 = true;
locate_template('404');
return;

How to: When a bp Group created, automatically create a wp category

You have to write this in your functions.php file of your theme:
function createCatAfterGroup() {

$group = $wpdb->get_row("SELECT * FROM `wp_bp_groups` ORDER BY date_created DESC");
wp_insert_term($group->name, 'category');

How to get changed post title in my custom plug-in which fires when 'save_post' is called?
I created a custom WordPress plug-in that hooks onto 'save_post" using add_filter(). I need to do something with the post titles and whenever a user changes the title, my plug-in cannot get the new title until the post is updated a second time (without changing the title in the admin a second time).
For example, I have a post named "WordPress Rocks". I change it to "WordPress is Cool", but my plug-in shows the title as being "WordPress Rocks" using get_the_title($post_id) when updating the post. I go back and make a second update to the post, this time without changing the title. This next time, get_the_title($post_id) shows the title is "WordPress is Cool".
How can I grab the updated title (if it's changed) as soon as the post is updated? | The second argument of the `save_post` action contains the post data:
do_action('save_post', $post_ID, $post);
You can also hook `post_updated` which will let you easily compare the before/after data:

Landing Page - Redirect Loop?

<?php
if($_SERVER['REQUEST_URI'] != '.../' || $_SERVER['REQUEST_URI'] != '.../'){
if(!is_user_logged_in()) {
wp_redirect( ' 301 ); exit;
}
}
I recently tried this piece of code and it works if i substitute say "<
However, if I substitute it with mydomain.com/landingpage i get a redirect loop error.
Any ideas?
Thanks! | What's happening is you're sending an unauthenticated visitor to a certain page. The code in that page also picks up that the user is unauthenticated, and sends them to the page that they're already on. Because the page keeps on sending the visitor to the same page, the visitor can't go anywhere. This is called a **redirect loop**.
You're on the right track with the `$_SERVER['REQUEST_URI']` check. However, paths like `../` and `.../` won't work. You need to use the actual URL of the page that you're redirecting to (sans the domain and protocol). Essentially, you need to use this code:
if ( trim( $_SERVER['REQUEST_URI'], '/' ) != 'landingpage' && ! is_user_logged_in() ) {
wp_redirect( home_url( 'landingpage' ), 301 );

Why would admin-ajax.php redirect to the home page for logged out users?
I am using the wp-polls plugin on my website. This plugin relies on using AJAX requests of the form
When I log in, this request works fine: it pulls the poll results from the server, and then displays them on the desired web page.
However, when I log out, this request redirects me to the home page. Thus, instead of the poll results appearing, I get the home page loaded where the poll results are supposed to be.
Why would admin-ajax.php redirect visitors to my Wordpress-powered site who are not logged in to the home page of my website? | It only redirects when accessed directly, as do all files located in `wp-admin/`. AJAX requests should work fine regardless of authentication status.
**Edit:** `wp-admin/admin-ajax.php` should _not_ redirect in any situation. Perhaps a plugin is redirecting all unauthenticated users to the homepage? By default, accessing files inside wp-admin/ when not logged in should redirect to the login page. | stackexchange-wordpress | {

Move from old custom field to new post_thumbnails

How do you use prepare when asking for a list of id's
I'm looking to get a number of records back from the database given a list of numbers and was wondering how I would use $wpdb->prepare to do this (to take advantage of the sanitising vs SQL injection attacks that it gives me).
A wrong way of going about what I'd like to achieve is `$wpdb->query($wpdb->prepare('SELECT * FROM wp_postmeta WHERE post_id IN (' . implode(',', $ids) .')` but this gives the chance of an SQL Injection attack (imagine one of the ids having the value "0); DROP TABLE wp_posts;").
NOTE: I'm not trying to select data from wp_postmeta, I'm just using it as example. | `$wpdb->prepare()` use the same syntax for formatting like php's `printf()`. SSo you will need something like `... WHERE post_id IN (%d,%d,%d) ...`
This will fit for three ids. But what if we got more or less than three ids? We will use the php tools to create the needed formatting string (assuming `$ids` is an array with the ids):
Count the IDs
count( $ids )
Create a string with a '%d,' for every ID in $ids
str_repeat( '%d,', count( $ids ) )
Now we have a string like `%d,%d,%d,`. There is one comma to much at the end. Let's remove it
$ids_format_string = rtrim( str_repeat( '%d,', count( $ids ) ), ',' );
And use this in this way `'... WHERE post_id IN (' . $ids_format_string . ') ...'` | stackexchange-wordpress | {

jQuery inluclude still seems ncessary for script to work within post
I have a jQuery script that works fine within a WordPress post as long as I include a reference to the jQuery libarary within the post.
`<script src="
From what I have read this is not the proper way to reference jQuery as it is already included within WordPress (using v3.4.2).
If I remove the inline reference the script fails and the console says that "$" is undefined. I also tried replacing "$" with "jQuery" according to articles that talk about NoConflict mode in jQuery.
My jQuery script can be viewed here in jsFiddle. | In order to use $ inside your script (You only need to change the wrapper of your script), use the following wrapper.
jQuery(document).ready(function($) {
// $() will work as an alias for jQuery() inside of this function
});

Royalty-Free Sliders used in theme development

How to modify/ customise NextGen Gallery's templates?
I would like to customise the "Image browser" template in particular. I'm trying to make clicking on an image redirects to the next image in a gallery, just like how Facebook image browser works.
(This is not a cosmetic change with CSS - CSS change is not what I mean by customising the tempaltes)
I can always edit `/wp-content/plugins/nextgen-gallery/view/imagebrowser.php` but it's a hack and it's not upgradable when next version of NextGen Gallery is out.

Shortcode output appears before post body
> **Possible Duplicate:**
> short code output too early
How can I insert my plugin code via shortcode inside post body in exact position?
The problem is that wp engine inserts the plugin code **BEFORE** post body all the time. Can it be fixed?
For example: I have some `[shortcode option="value"]`, that generates some text with image inside div container. When I put it inside the post **AFTER** the text, wp outputs this code:
`<div> here is my plugin code </div> <p> here is the text of the post </p>`
… and so it gets in the top of the post.
Where is my fault? | I have had this problem before: shortcodes shouldn't **display** any content (using `print` or `echo`), instead `return` the content to be outputted.
If it's too much trouble converting all of your output statements, or you need to use a function that will always display the output, you can use **output buffering**. A buffer will 'catch' any `echo`'d or `print`'d content and allow you to write it to a variable.
function my_awesome_shortcode( $atts, $content = null ) {
// begin output buffering
ob_start();
// output some text
echo 'foo' . "bar\n";
$greeting = 'Hello';
printf( '%s, %s!', $greeting, 'World' );
// end output buffering, grab the buffer contents, and empty the buffer
return ob_get_clean();
}
add_shortcode( 'awesome', 'my_awesome_shortcode' );

Count singular post views automatically
I'm trying to add some function to each loop called in the themes. What I'm doing is I add a function to count post view from here post views without plugin, to use the function I need to add this line `<?php setPostViews(get_the_ID()); ?>` to `single.php`, `page.php`, etc.
I want to know whether I can use some hook to automatically add the `<?php setPostViews(get_the_ID()); ?>` line without hard code it for each `single.php`, `page.php` files. | You could hook into `template_redirect` and execute a helper function:
add_action( 'template_redirect', 'wpse_75558_count' );
function wpse_75558_count()
{
if ( is_singular() )
setPostViews( get_the_ID() );
}
To **display** the post views, you have to use a later hook. I would recommend `the_content`:
add_filter( 'the_content', 'wpse_75558_show_count' );
function wpse_75558_show_count( $content )
{
$count = getPostViews( get_the_ID() );
if ( ! is_numeric( $count ) )
$count = ''; // prevent errors showing to visitors
else
$count = "<p class='view-count'>Views: $count</p>";
return $content . $count;

How to use same email for multiple users

I should figure out some other solution for that. I know that I could use something like adding +sometext to every email, so it will show different to Wordpress. Do you have some other solution, that can be done here? | You can use `wpmu_validate_user_signup` filter to remove the error and then define `WP_IMPORTING` just to skip the `email_exist()` check in `wp_insert_user()` function:

Redirect user on second visit on page

Then I want that page not be available on same user for the second time, if the will try, I want them to be redirected. Is this possible?, should I use plugin? Thanks. :) | As mentioned in a comment above the cookie solution will not totally do the trick. If it's ok that they can revisited the welcome page from a different browser or if they delete cookies. This is fine.
If not I would use the database. I think easiest would be to regard the time the user was registered.
Like if the user registered within the last 60 minutes offer the welcome page. If not forward somewhere else.
This solution does not require you to alter the database and does not have the drawbacks of the cookie. If you want to offer a limited time offer for newly registered this might be a good way. You can even combine this with the cookie. That way you make sure the visitor can only see it once on his first device. And if he logs in on his second device more than 60 minutes later he will not see it either. | stackexchange-wordpress | {

When do I need to use esc_attr when using WordPress internal functions
When I am putting a WordPress value inside the attribute tag, for example, the following method does not need `esc_attr`
e.g.
// JS code
alert('<?php echo get_bloginfo('name');?>');
the following method does need `esc_attr`
// JS code
alert('<?php echo esc_attr($post->post_title);?>');
What is the convention used? | You can look at the Codex.
> Encodes < > & " ' (less than, greater than, ampersand, double quote, single quote). Will never double encode entities.
Given that, arguably, both of those strings need sanitization. Imagine a site name like `>> "My" Website's Great Title <<"`
Also, since you are using this in Javascript, you should probably be using `esc_js` instead.
The convention is, "understand how markup works, and how malicious hackers work, and act accordingly." That is how you know how to use these functions. Also, **Trust No One**.

Practical Solutions to HTML5 Video on WordPress
I was directed here from Stack Overflow --
We work with clients who have WordPress sites and one thing we keep struggling with is implementing HTML5 video across all browsers and devices in the WordPress environment. We've tried multiple plugins (JW Player, MediaElement, Sublime Video). It seems like each one has its own bugs, and are difficult to implement video play-lists on (Not to mention having a good UI for the client to manage/add videos themselves).
What is a solid, reliable solution to HTML5 video on WordPress? Something that can support up to 4 file types at once (.mp4, .webm, ogg, flash) and possible have a playlist functionality.
Should I ditch the plugin solution entirely and write the code myself? | In an old project, I ended up writing my own. And working with WordPress library to feed the players (audio and video), so there's no foreign UI and a template builds the player with the proper attachment info.
The audio player was implemented with JPlayer.
> ### The jQuery HTML5 Audio / Video Library
>
> jPlayer is the completely free and open source (GPL/MIT) media library written in JavaScript. A jQuery plugin, jPlayer allows you to rapidly weave cross platform audio and video into your web pages. jPlayer's comprehensive API allows you to create innovative media solutions while support and encouragement is provided by jPlayer's active and growing community.
If my memory serves me well, I think I had to use another library to the video due to some playlist issues.
And that was done with this premium player: HTML5 Video Player with Playlist. They have a WordPress plugin version, but I needed something very customized, so built my plugin with the Html5 code. | stackexchange-wordpress | {

{
global $pagenow;

the_excerpt() or get_the_excerpt with shortcode escape
I have few posts which have a dropcap shortcode wrapped around the first character like so:
[dropcap]T[/dropcap]his is a dropcap.
The replacement for this shortcode yields:
<span class="dropcap">T</span>his is a dropcap.
However, when I call the_excerpt() or get_the_excerpt() on these posts, its returning:
"his is a dropcap".
I need it to return "This is a dropcap" as if no shortcode exists. | You can make WordPress execute your shortcode in the excerpt by hooking into `get_the_excerpt` filter and overwriting the default `wp_trim_excerpt` function, which is responsible of stripping the shortcode tags from the excerpt as pointed by Chip:
add_filter('get_the_excerpt', 'do_my_shortcode_in_excerpt');
function do_my_shortcode_in_excerpt($excerpt) {
return do_shortcode(wp_trim_words(get_the_content(), 55));
}
This is applied to both `the_excerpt()` and `get_the_excerpt()` outputs. If you want to apply it only for `the_excerpt()` output, hook to `the_excerpt` filter:
add_filter('the_excerpt', 'do_my_shortcode_in_excerpt');
function do_my_shortcode_in_excerpt($excerpt) {
return do_shortcode(wp_trim_words(get_the_content(), 55));

A static text string, such as `<p>Hello world!</p>`, is wrapped in an appropriate translation function, such as `<p><?php _e( 'Hello World!', 'themify' ); ?></p>`, to make it available for translation.

The field's name is first_name, but adding `<input type="text" name="first_name" id="first_name" value="<?php echo $_POST['first_name']; ?>" required="required" placeholder="<?php _e('First Name'); ?>" />` doesn't work for some reason. The form submits fine, but the profile doesn't get the "First Name" field filled in in the back end.
I'm editing this plugin to tweak the register form: < | I found an excellent, free plugin that gets the job done.

Very easy to use, adds fields to both the register and the profile pages. | stackexchange-wordpress | {

how can I do something on new user registration?
When I register a new user to my blog, I always receive an email. The code in simple terms should look like this.
on_new_user_registration(){
//send email to admin
//I want to do something else.
}
I would like to do more than receiving an email. Can someone point me to the right code.
I have tried using the `wp_insert_user()` function in wordpress but that creates the user inside the editor.
thanks a lot. | You want to use the `user_register` hook, probably. Then use the Filesystem API to make the folder.

Why does abstracting html from plugin code result in loss of access to wordpress functions?
When defining the callback that produces the HTML content for an admin settings page, I'd like to abstract the HTML into a separate file, but the HTML uses some wordpress functions, specifically current_user_can and screen_icon. These are claimed to be undefined when called through the included file but work fine inline.
function admin_menu_page_content() {
if ( !current_user_can( 'manage_options' ) ) {
wp_die( __( 'You do not have sufficient permissions to access this page.' ) );
}
?>
<div class="wrap">
<?php include(plugins_url('plugin_name/forms/admin_form.php')) ?>
</div>
<?php
} | Use `plugin_dir_path()` to include executable files. `plugins_url()` returns the web address, that’s not what you need.

querying posts by custom taxonomy terms right from a querystring based URL
The following URL seems to work for cats and tags only.
`yoursite.com?cat=2&tag=bread1+bread2`

is there an equivalent to something like the following?
`yoursite.com?taxonomy=food&tag=bread1+bread2` | This should work :
yoursite.com/taxonomyname/bread1,bread2

making users able to add their own products wp e-commerce

The problem is that I want to allow all users to post their products on the website.
Right now, only the admin can add products.

get_the_post_thumbnail wordpress 3.5
For some reason the following isn't loaded anymore in wordpress 3.5. Does anyone know how to fix the `get_the_post_thumbnail()` ?
I'm using the follow code:
echo "<div class='meta_apps'>";
echo "<a href='"; the_permalink(); echo "'>";
echo "<div class=\"meta-icon\">".get_the_post_thumbnail($post->post_id, 'thumbnail', $attr)."</div>";
echo "<div class=\"meta-title\">".$post->post_title."</div>";
echo "</a>";
echo "</div>"; | I could be mistaken, but I don't think `$post->post_id` works to retrieve the post's ID. I believe you want `$post->ID`. So that was probably your issue to begin with, though without seeing your `$attr` array, it's hard to say. Here's a reference for `$post`'s properties. In this case, `get_the_post_thumbnail` is the more appropriate function.
In your answer you posted for yourself, you're using `the_post_thumbnail` incorrectly. First off, you don't need to echo it; `the_post_thumbnail` will output the thumbnail. Side note: Any function in `WordPress` that starts with `the_` is almost always going to output something automatically. Second, You don't need to pass it `$post->ID` (again, using the wrong property). Third, the first property of `the_post_thumbnail` is the size, e.g. "thumbnail". | stackexchange-wordpress | {

wp_list_pages: only show subpages on the parent page?

— Gallery
— Subpage 1
— Subpage 2
— Kitchen
— Disclaimer
How am I going to do this with the `wp_list_pages()` function? | This would probably be better achieved using CSS. First, you hide all .children:
.page_item .children {
display: none;
}

Create second custom 404 page for selected post type
I created a new custom post type called `event`, which works fine.
I also created a custom `404` page template, which is shown if a event/page/post is not found.
But now the hard part, i want to create a custom 404 page for event post type. So this 404 page is only shown if a event is not found. But the default 404 page should still work with posts or pages.
Thanks | Two options:
1. Use conditional code inside of `404.php`, to output different content/markup for the post-type
2. Intercept the template at `template_redirect`, and include a separate template file for a 404 for the post-type.
Personally, I'd go with option 1, as it is easier and more intuitive. | stackexchange-wordpress | {

How to delete all post and attachments of a user when I delete it?
When I delete a user, WordPress can just delete the post or page of this user, not his custom post and his attachments.
An idea for a special hook?
add_action( 'delete_user', 'my_delete_user');
function my_delete_user($user_id) {
$user = get_user_by('id', $user_id);
$the_query = new WP_Query( $args );
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
wp_delete_post( $post->ID, false );
// HOW TO DELETE ATTACHMENTS ?
}
}
} | The hook you choose is appropriate, and here is how to use it to delete all posts of all types (posts, pages, links, attachments, etc) of the deleted user:
add_action('delete_user', 'my_delete_user');
function my_delete_user($user_id) {
$args = array (
'numberposts' => -1,
'post_type' => 'any',
'author' => $user_id
);
// get all posts by this user: posts, pages, attachments, etc..
$user_posts = get_posts($args);
if (empty($user_posts)) return;
// delete all the user posts
foreach ($user_posts as $user_post) {
wp_delete_post($user_post->ID, true);
}
}
If you only want to delete user attachments, change the `post_type` arguments from `any` to `attachment` and use `wp_delete_attachment($attachment_id)` instead of `wp_delete_post()`. | stackexchange-wordpress | {

permalink results to "page not found"

WP native tag suggest metabox. How does it process tag id?
As you know, there is a metabox that suggests tags as you type to input box. Is anyone knows how this function gets the tag's ID (term_id) which is selected? I have looked at some of the core files but it seems only the tag name is retrieved and the ajax response returns only the name, no sign of id.
But it's just impossible as the tag is updated **by the tag's ID but not it's name** upon submitting or updating the post
The core files i've looked at:
wp-admin/includes/meta-boxes.php
wp-admin/js/post.dev.js
wp-admin/admin-ajax.php
wp-includes/post.php
wp-includes/js/jquery/suggest.dev.js
wp-includes/taxonomy.php | It just passes the tag names to wp_update_post(), which eventually calls wp_set_post_tags(), which eventually converts the names to `term_id`s, using term_exists(). | stackexchange-wordpress | {

How to implement styling of div in the front end using plugin admin meta box settings?
I have a plugin meta box (in the Wordpress admin) with the following fields and values:
Name of the div class selector= featured_content
Font family= Verdana
Font color= #000
They are stored in the Wordpress post meta table.
In the Wordpress front end, one of the content template has this div:
<div class="featured_content">
The quick brown fox jumps over the lazy dog.
</div>
How would I communicate with the Wordpress front end from my Wordpress meta box settings for that div? So that when the page is loaded containing the div class selector name of "featured_content", proper styling would be implemented based on the backend meta box settings.
I am thinking of running a JS code to scan all id and class selectors then query via AJAX to retrieve the settings and implement them, but I'm not sure if this is the best way.
Thank you for any tips. | The answer is really simple, I never thought at first. You will simply create a custom CSS function inside your plugin and then use PHP to output the meta values and hook that to wp head. | stackexchange-wordpress | {

How to make remove display none to this div container in post meta box?
I am adding meta box via add_meta_box hook but it is not showing in the admin panel, I double check the source code and it seems hidden because of this line:
<div class="postbox-container" id="postbox-container-2" style="display: none;">

#postbox-container-2 {display:block;}
b.) Using jQuery like:
$('#postbox-container-2').css('style','');
OR
$('#postbox-container-2').show();
OR
$('#postbox-container-2').css('display','block');
OR
$('#postbox-container-2').removeAttr()('display');
How to make that div appear? Thank you for any tips. | This did the trick, in jQuery:
//get page title
var edit_title_page=$("html head title").text();
//Confirm if this is right Edit page
if (edit_title_page.indexOf("Edit Form") >= 0) {
$('#postbox-container-2').removeClass("postbox-container");
$('#postbox-container-2').css('width','100%');
$('#postbox-container-2').css('float','left');
$('#mymetaboxID').show();
}
It will first check for edit page title, if it's on the right page, remove the post-box container containing the display none, then apply a new css styling.

Finding URI in Child Theme
Which is best way to find URI in child Theme.
<?php echo get_template_directory_uri(); ?>
<?php bloginfo('template_directory'); ?>
Below given code works but it has "stylesheet" in it, sounds like its a hake to find URI. Is this the only solution ?
<?php echo get_stylesheet_directory_uri(); ?>
<?php bloginfo('stylesheet_directory'); ?> | Yes, `stylesheet` is for child themes, `template` for parent themes. Andrew Nacin has explained that recently on wp-hackers:
> child themes were originally just `style.css` and `functions.php`. That's why "template" refers to the parent theme and "stylesheet" refers to the child theme. | stackexchange-wordpress | {

bloginfo('stylesheet_directory') vs. get_stylesheet_directory_uri() and include('file.php') vs. get_template_part()
In my custom theme I'm using `<img src="<?php bloginfo('stylesheet_directory'); ?>/images/logo.jpg"/>` to load my custom logo.
I'm using a custom sidebar for `front-page.php` and that's why I used `<?php include('sidebar-front.php') ?>` to get it.
But when I'm using the 'theme-check' plugin it's suggesting to change the following:
* `bloginfo('stylesheet_directory')` to `get_stylesheet_directory_uri()`
* `include()` to `get_template_part()`
So, I did the following:
* `<img src="<?php get_stylesheet_directory_uri(); ?>/images/logo.jpg"/>`, and
* `<?php get_template_part('sidebar-front.php') ?>`
But both failed here. The logo doesn't load and the sidebar isn't too. I used `<?php get_sidebar('front'); ?>` and it's working fine.
I just want to speculate what the problem with those suggestions? It's WP 3.4.2 here. | `get_stylesheet_directory_uri()` returns a value, it doesn’t print anything. So you have to use:
echo get_stylesheet_directory_uri();
`get_template_part()` is just a wrapper for `locate_template()`. But the latter has one advantage: It returns the path of the file it has found. Try the following:
$path = locate_template( 'sidebar-front.php', TRUE );
