Wordpress custom styles in menu page
I have added a menu page to my plugin. In the wp codex is described that I can use a seperate .php file for the content of the menu.
function register_custom_menu_page() {
add_menu_page('custom menu title', 'custom menu', 'add_users', 'myplugin/myplugin-index.php', '', plugins_url('myplugin/images/icon.png'), 6);
}
myplugin-index.php
<?php
echo "Admin Page Test";
?>
Now I want to use custom styles (.css) in the myplugin-index.php. How can this be achieved?
BR,
mybecks | You could use
<!doctype html>
<head>
<style type="text/css">
#toplevel_page_custom_menu_title{
display:none !important;
}
.update-nag{
height:auto !important;
}
</style>
</head>
<body>
<div class="update-nag">
<?php
echo "Admin Page Test";
?>
</div>
</body>
</html>
You can enqueue this way
function prefix_add_my_stylesheet() {
wp_register_style( 'prefix-style', plugins_url('style.css', __FILE__) );
wp_enqueue_style( 'prefix-style' );
}
add_action( 'admin_enqueue_scripts', 'prefix_add_my_stylesheet' );

Plugin to send messages to members/lists but not full-blown newsletters
I'm looking for a plugin that would allow the owner of a school to send student members short email messages. We don't need a full-blown newsletter feature but it does need to be able to have multiple lists (kids classes, adult classes, etc). Users don't need to talk to each other, just get a message that, for instance, the 10am class is cancelled, etc. Something like mailchimp seems like overkill and too much work for the client. Ideas?

Force User Login
Surprised I haven't found this Q.
I want to force users to login to the site before accessing any of the content.
I have this function:
function av_force_user_login() {
global $post;
global $pagenow;
if ( in_array( $GLOBALS['pagenow'], array( 'wp-login.php', 'wp-register.php' ) ) ) {
return;
}else{
auth_redirect();
}
}
add_action( 'get_header', 'av_force_user_login' );
This doesn't seem to work though and after I try and login I get redirected back to the login page.
One caveats to watch out for (in my case): I'm using BuddyPress' registration system which doesn't apply to the login page but it would apply to the `wp-login.php?action=register` page which redirects to Buddypress' template for registration.
Nevertheless, is there anything wrong with the above code that would cause a redirect back to the login page? | Very Basic Script. This should work.
add_action('template_redirect', 'redirect_to_login');
function redirect_to_login(){
if(!is_user_logged_in()){

How to implement a secondary menu?

* Starting depth and maximum level to display + flat display.
* Display all menu items starting with the selected one.
* Display only direct path to current element or only children of selected item (option to include the parent item).
* Custom class for a widget block.

Get current post featured image ID
Is it possible to retreive the current post (inside the loop) featured image ID?

?>

How to control who can view certain pages in BuddyPress?
I would like to control who can see a page in BuddyPress and restrict anyone else from accessing it.

// Show page
<?php } else { ?>
// "You are not allowed to view this page" message

1. To be able to **control who can see the page** , not just any logged in user.
2. I also need to **control which pages this applies to** , not just any page.
I am new to BuddyPress so I don't know **which functions and variables to use** here.
I imagine something like this could be done in the template files, or maybe in the _bp-custom.php_ file. **Or is there a better solution to this?** | > I am new to BuddyPress so I don't know which functions and variables to use here.
Read the codex - for example: <
You could create a function in your theme- functions.php or in bp-custom.php and call it from template files and pass it parameters like allowed_users, etc.
Or you code hard-code something like this into specific template files.
global $bp;
$allowed_users_array = (1,4,5,7);
if (in_array($bp->loggedin_user->id, $allowed_users_array)) {
// Show page
} else {
// "You are not allowed to view this page" message
// or load a custom error page using locate_template( array( 'some.php' ), true );
// or redirect somewhere by using bp_core_redirect( );

Which is better: 301 Redirect in my .htaccess file or a plugin like Redirection?

Are there any performance benefits (i.e. site loading) o using a plugin like Redirection or should I just stick to hardcoded 301 Redirects? | The `.htaccess` catches requests before WordPress is even started. That’s _much_ faster than any plugin.
For a handful of redirects I wouldn’t install a plugin. You need that only in cases when the server cannot know the new address, for example if you rename permalinks (slugs) automatically (you shouldn’t ;)). | stackexchange-wordpress | {

Attachment Image using wrong src?
I've had some issues recently with this code below to display the featured image of a page:
add_theme_support( 'post-thumbnails' );
add_image_size("homepageFeatured", 250, 250, false);
wp_attachment_image(get_post_thumbnail_id($post->ID), 'homepageFeatured'); //in the loop

Any ideas on why this is occurring?

One post carries 30 postmeta values, is this too much?
I have some data saved as post meta, occasionally some plugins may save an extra piece. Now I installed bbpress, it saves at least 10 pieces of post meta. Adding them together, there are nearly 35 pieces of post meta per post. I think WordPress can handle much more if without bbpress.
**With bbpress forum, the number of posts will increase dramatically, multiply by the number of post meta, it will be a huge post meta table**. Will it be a problem? | No, to be honest 35 is nothing. You should not see any problems scaling this into the hundreds/thousands if optimized right, it does depend on many factors.
Where is the post meta being used, are you sure it's all being used?
Are you using a lot of unique keys? You can check this by doing `get_post_custom_keys`, the lower the better.
Are you outputting all post meta in one shot using `get_post_custom` instead of getting each field via `get_post_meta` ?

A question about .htaccess
I'm redeveloping a site for a client.
Their current site is written in .asp. I've rebuilt in WordPress as they need a CMS.
We're repointing the DNS to our hosting environment.
My question is - I need to set up an .htaccess file (I think this is the best way) to redirect all the old URLs to their new equivalent. Some of the URL structures have changed so it's not just a case of changing .asp > .php. Soo... where should I upload the .htaccess file - does this need to go in the root directory OR does it need to go in my wp-theme folder?
Thanks | You can just add the .htaccess to the root of the website however be cautious as WordPress will have added it's own if you have changed the link slug structure within the WordPress admin.
In the htaccess file you should use 301 re-direction's like so:
redirect 301 /oldpage.asp
If it is a big site then you will not want to re-direct all pages although it could be worth while. I normally just do a Google site: search and re-direct the most important pages and any with first or second page listings. | stackexchange-wordpress | {

WP_Query vs get_posts
I have read a **number** of **questions** on SE regarding these but I still can't figure the exact difference wrt usage. Would it be true to say that I would probably use WP_Query for the majority of secondary loops and only use get_posts if I need the results returned in an array, or to put it another way is the main difference between the two the array vs object return, or is there some other major factor I should be aware of? | ### The difference between get_posts & WP_Query
You can view `get_posts()` as a slimmed down `WP_Query`. In fact looking at the source:
//... prepares query array $r
$get_posts = new WP_Query;
return $get_posts->query($r);
`get_posts()` use `WP_Query`, but only returns an array of posts - nothing more. Furthermore it sets:
$r['no_found_rows'] = true;
Normally (by default with `WP_Query` object) - WordPress queries how many posts there are in total - even if you are only after the first 10. It does this so it can perform pagination. So `get_posts()` is actually (slightly) quicker (it also ignores sticky posts).
### Which to use...
If you only need an array of posts, and don't _need_ the query object -use `get_posts()`. Otherwise, if you do need the access to the query object methods, or pagination, or sticky posts at the top, you should use `WP_Query`. | stackexchange-wordpress | {

wp_reset_postdata();
wp_reset_query(); | There's no need to use them both.
You should only use `wp_reset_query()`, if you modified query with `query_posts()` (which you should avoid). This function also call `wp_reset_postdata()` \- <
So it's better to use `wp_reset_postdata()` after running separate query. | stackexchange-wordpress | {

Get the number of rows from $wpdb->get_results not working

$nr = $myquery->num_rows;

Important: using $wpdb->get_results like this:
* Do I need to prepare the query (i read it in the codex)?

WordPress Attachments vs Post Meta
Apologies if this is not a _question_ and belongs more in discussion, but In dealing with image attachments for a portfolio site, what is the benefit to having images be "attached" to a post versus saving the image IDs as an array in a post_meta field? | The WordPress "gallery" functionality partly depends on the attachment of the media to the post via the `post_parent` column.
> Specifying IDs in your shortcode allows you to include images in your gallery that aren't necessarily "attached" to your post — that is to say, not uploaded from within your post or page. This flexibility allows you to create and embed any number of galleries containing any number of images!
>
> Note: If you choose to just use the "barebones" version of the [gallery] shortcode in your post or page, only images that are "attached" to that post or page will be displayed.
>
> <
You can see in the source that shortcode uses `get_children`, which has quite a comment block in the source, and again you can see that `post_parent` is a key factor.
There are probably other ways to answer the questions but that is the first that comes to my mind. | stackexchange-wordpress | {

How to properly print a 404 error without redirecton? (i.e. keeping the current URL)
There are some pages on my BuddyPress install that I would like to hide by printing a 404 error.
With the help of the following question: Redirect Restricted Page to 404 I came up with this code:
global $wp_query;
$wp_query->set_404();
status_header( 404 );
get_template_part( 404 );
exit();
Most of the page is hidden nicely and a 404 error is printed, however what has been printed before this code remains (including the header title of the page I want hidden).
Unfortunately I can't move this code higher up, before anything gets printed.
So is there a way to **clear everything that has been printed before** and then **print a fresh 404 error** but with **keeping the current URL**? (So no redirection to the 404.php page.) | You should be using a filter outside of your template for this:

status_header( 404 );
$template = locate_template( '404.php' );

Query for recent images across multiple posts
I'm a bit fresh to wordpress theme development (and PHP in general), and I'm curious if there is a way to query XX number of recent images, likely spanning across multiple posts. Basically I want to create a widget that shows a 3x3 set of the most recent images used in posts.
Any thoughts on how one would accomplish this? | You can use `get_posts` or create a new `WP_Query` using the following args (or something similar).
<?php
$args = array(
'post_type' => 'attachment', // attachment post type
'post_status' => 'inherit', // all attachments have this post status
'post_mime_type' => 'image', // make sure you get images only
'posts_per_page' => 5 // however many images you want
);
When looping through the images, you can use `wp_get_attachment_image` or `wp_get_attachment_image_src` to grab the image HTML or image URL respectively.
<?php
$attachments = get_posts($args); // args from above
foreach($attachments as $a)
{
// replace `thumbnail` with an appropriate image size
echo wp_get_attachment_image($a->ID, 'thumbnail');

Second tier sidebar navigation

link2-2
link2-3
link3

'depth' => 0,
'child_of' => $first_parent->ID,
'title_li' => __($first_parent->post_title),
'sort_column' => 'menu_order',
); ?>
<nav class="sidebar">
<ul>
<?php wp_list_pages( $args ); ?>
</ul>
</nav> | For now I have decided to use a CSS solution. I realized with the code above I do actually have classes I can work with. For example if you had this navigation in a you could use something like this.
nav.sidebar li li li {
display: none;
}
nav.sidebar li li.current_page_item > ul > li, nav.sidebar li li.current_page_ancestor > ul > li {

confusion with add_filter
I am trying to customize the default WordPress search field. So I thought I could add a filter to remove the function and then add in a new function with the fields the way I want them. So I tried this

function if_restrict_categories($categories) {

if (is_admin() && $onPostPage && !current_user_can('level_10')) {
$size = count($categories);
for ($i = 0; $i < $size; $i++) {
if($categories[$i]->parent != $a && $categories[$i]->term_id != $a){
unset($categories[$i]);
}
}
}
return $categories;
}
add_filter('get_terms', 'if_restrict_categories');
And where `get_cat_if_user()` is a custom function where I get the category I've assigned to my user.

Form that sends data to an admin panel and can export it
Is there a way to have a form submit data to a admin control panel where the data is stored and can be rectified there? Could it also be able to export the data as excel for example? | there are 2 very popular form plugins
1. Gravity Forms \- extremely customisable and saves all data to your database (Commercial)
2. Contact Form 7 \- also saves everything to your database and easy to use (Free)
Both send the data to the Admin panel so you can review inside WordPress.
I know that Gravity Forms has an option to EXPORT the form entries as a CSV file.
**Review Form Submissions without logging in**
Both can send email notifications to your email address so you can see what has been submitted without logging into WordPress.

Multiple sub directories for theme template pages
I apologize if this questions has already been answered, I have a feeling I'm just not using the right terminology for my search.
I'm in the process of building a base theme for my employer. One of the things we want to do with this new theme is have the option to switch from a standard template to one that's been Zurbified. The way I'd prefer to handle this is by having an admin panel checkbox.
Within the theme itself we want to have 2 separate folders that contain the actual theme template files (Ex: `theme_folder/normal/page.php || theme_folder/zurb/page.php`).
How would I go about properly processing this? Is there a hook/filter that allows you to specify which sub folder to use in the specific situation? From what I read its possible to have the sub directories house the template page files,

if(is_404()) {
get_header(`error`); //loads header-error.php
} else {
get_header(); //loads header.php
}
In your case, you want to load a completely different template, Now the only action hook I can imagine is - `template_redirect`, Which can be used to tell wordpress to load a different template as per conditions.
**Example -**
function wpse62337_zurbified() {
if ( CONDITION ) {
include (TEMPLATEPATH . '/zurb/page.php');
exit;

Categories: A Greenhorn Question on Strategy (Not Code)
Im having an issue in my category set-up logic
Let's say I sell new/used (including Vintage) Drums/Drum Parts wherein a user can search by new, used or by individual part. So let's say they choose to search by individual part on Cymbals. The search results page should then display a listing of Cymbals should also be grouped by new/used? Right?

## New
* Drum Sets
* Cymbals
* Toms
## Used
* Drum Sets
* Cymbals
* Toms

Plugin: Events Manager - Search by start date only
EDITED MY QUESTION TO MAKE IT WAY MORE CONCISE

Events manager settings page -> Pages tab -> Event/List Archives

Generate page title tag from the content of H1
Is there any way of generating the title tag of a page from the content of an H1 tag on my wordpress page?

Running a function only once when a taxonomy term is changed
Probably quite a simple problem.. I have a custom post type with taxonomy terms. I wish to run a function from my functions.php whenever the admin ticks a specific term box.
My original thought was to use add_action along with a "save_post" action so when the post is saved, it would loop through my terms and if the desired one is selected, it would run the function.
This is all good, except each time the admin updates the post it would run the function. The function is sends an email to a user, and I onyl want this email sent out ONCE.

How to add and remove a page
I'm creating a plugin that will need to add a new WP page upon activation and then I want it to remove that same page upon uninstallation. Do I have to manually store that page id in the DB somewhere or is there a native WP option to remember that automatically?
My code so far:
register_activation_hook(__FILE__, 'create_page');
register_uninstall_hook(__FILE__, 'remove_page');
function create_page() {
global $user_ID;
$page['post_type'] = 'page';
$page['post_content'] = 'Page content will go here.';
$page['post_parent'] = 0;
$page['post_author'] = $user_ID;
$page['post_status'] = 'publish';
$page['post_title'] = 'Page Title';
$pageid = wp_insert_post ($page);
if ($pageid == 0) {
echo "Something went wrong. Could not successfully add a new page.";
}
} | Why do you need to create a page?
Its possible that before plugin deactivation, the page no longer exists, so your deletion function will need to check for if it exists
But yes you will need to store the ID somewhere. Best option is to just update_option('icreatedapage', $pageid);
if ($pageid == 0) {
echo "Something went wrong. Could not successfully add a new page.";
} else {
update_option('somename_relatedtoyour_plugin_name', $pageid);
}

WordPress and Git: How does Git interact with your IDE?
Everyone has been telling me I should use Git. What I don't understand is how git interacts with your IDE. Say i'm developing on Dreamweaver, and I switch branches, my IDE isn't going to reflect that so how do I get the two aligned? Plugins? = more complicated than simple FTP sync ...
Or am I missing something? | I don't know Dreamweaver at all, but it certainly has the ability to know when an underlying file has changed, yes? Suppose you open an html file in Dreamweaver. Suppose you open it also in vim or TextWrangler; were you to save it in vim or TextWrangler, would it throw an alert to reload the file in Dreamweaver?
If so, that's all changing branches will do.

Remove the Yoast SEO Post Metabox

I've tried putting a `remove_meta_box` call in on admin_init, trying to remove the action on $wpseo_metabox but to no avail.

WordPress SEO adds meta boxes on `add_meta_boxes` action with default priority - 10, which run after `admin_init`, so that won't remove them. Instead you need to hook into `add_meta_boxes`, but with lower priority - 11, 12, etc.

What filter or action hook to use in order to load some code before the template begins printing in BuddyPress?

Divs appearing everywhere in post content
Whenever somebody writes a post on our site, the Paly Voice ( there are automatically a lot of `<div>` elements created. This is bad for layout, since we have a style that applies to divs that we don't want to apply to story styles.
Is there a way to remove the automatic div insertion? If not, can I add a function hook to parse the post and remove them before saving to the DB?
Edit: Example here: < | You first should find out where the divs are coming from, since that's not normal behavior. Could be from a plugin or - as Damien said - copy-pasting a text from Word.
To remove the divs you can do a simple
str_replace(array('<div>', '</div>'), '', $content)
either before storing the text in the database (by hooking on `save_post`), or before displaying it on the site (by adding a filter on `the_content`).
EDIT: I was wrong, you don't hook on `save_post`, but instead you filter on `wp_insert_post_data`. This function below should work:
function remove_divs($data) {
$filteredContent = str_replace(array('<div>', '</div>'), '', $data['post_content']);
$data['post_content'] = $filteredContent;
return $data;

How to include a plugin's php file to another plugin functions file

With the second include you're trying to include an URL which is disabled by the server for security reasons.
However, why do you need to include the function of plugin B? If plugin B is present that means it's probably activated, which in turn means you can use the function directly from plugin A without needing to include the file specifically. | stackexchange-wordpress | {

Problem with caching, W3TC
Am using W3TC from a long time but from past few weeks am stuck, as I can't see my edits working. It was all fine in past but from a week my edits in style.css reflects back in like an hour after.

For example, if you are including it in the header.php file:

Of course that will keep it from being cached... ever. So you might want to turn it off and on. You could add a variable to activate it or you could tie it to wp_debug:
<link rel="stylesheet" href="<?php echo get_stylesheet_uri(); ?><?php if ( defined('WP_DEBUG') && ! WP_DEBUG ) echo '?v='. time(); ?>" />
Or just comment it out when you are done:
<link rel="stylesheet" href="<?php echo get_stylesheet_uri(); ?><?php #echo '?v='. time(); ?>" />

conditional tags- how to use with shortcodes
I have a salon website with a gallery page wherein the user must first select a stylist prior to viewing their individual gallery.
I planned on using NextGen to house the images in stylist specific galleries, and using the NextGen shortcodes(ex: `[nggallery id=1]`) to determine which gallery gets shown on the specific page.
After doing a bit of research, I think WP's conditional tags (I'm thinking `is_page( # )`) might be the best route to take for this, I'm just not sure how to integrate the conditional tags to specify/define the page and the NextGen shortcodes.
Any tips, help, advice, etc. is greatly appreciated. | I am not sure to understand your question, but you have to read more wordpress/nextgen documentation.
What you need to do exactly? Can you be more specific?
I think, that if you create a set of pages (for each stylist) and use the respective shortcode of the gallery in the content, this will work fine.
ex: in the page REBECCA HAEHNLE (page_id=29) use `[nggallery id=ref_stylist_galery]`
On the mother page (gallery), use the album shortcode (create an album with all the stylists galleries in order you want) `[album id=ref_album_id template=extend]`
I think it will do the trick :)
In other words, you can do something like this in your **page.php** template:
if( is_page(ID_OF_SPECIFIC_PAGE) ) {
// make your stuff here
echo do_shortcode('[nggallery id='.$my_id.']');

Is it possible to control content on different pages by checkboxing wich content is shown where on a wordpress theme page?
i have created a sidebar in my wordpress site.
i want this sidebar to be displayed on each of my pages and subpages in their respective admin editors.
i want the sidebar to contain a list of specific posts with checkboxes to select them independantly or together.
each checked post must then be displayed on my site where i call the sidebar.
is this possible? can anybody direct me towards a plugin that can accomplish this? | You can use the WordPress Settings API to do what you're looking for.
You can follow this - WordPress Settings API Tutorial _( www.ottopress.com )_ to setup an options page, and depending upon the options saved in database you can show different content.
**Example -**
<?php
// get the stored value in variable - foo
$foo = get_option('option_name');
if ( $foo == 1 ) {
echo 'check box in CHECKED';
} else {
echo 'check box in NOT CHECKED';
}
### Update -
Yup there's Options Framework plugin plugin which can be used for this purpose.
> The Options Framework Plugin makes it easy to include an options panel in any WordPress theme. It was built so developers can concentrate on making the actual theme rather than spending time creating an options panel from scratch. It's free to use in both commercial and personal projects, just like WordPress itself.

Script for initializing JQuery Masonry for Wordpress
What is the different between this ( and ( for JQuery Masonry.
Why does the first one work and the second one doesn't.
In both cases I used wp_enqueue_script to add the script.
Thanks! | This executes, when the DOM has been constructed, before all content has been loaded
$(document).ready(function(){ ... });
$(function(){...}); // short form
This executes, when all content has been loaded
$(window).load(function(){ ... });
This executes immediately, when it is first encountered by the browser
(function(){ ... })();
The latter is known as a self-executing anonymous function, which is very handy, but not here, because no content or not the right content may have been loaded when it self-executes. | stackexchange-wordpress | {

How to allow empty title for attachments?
* When adding an image attachment to a post, the Title field is always filled automatically with the file name.
* For some images I change this into something more meaningful, for other images I want this field to be empty (in my theme I'm displaying this title field as a caption below each image, but not all images should have this caption).
* However, if I clear the Title field, it shows again the file name upon save - with the message " **Empty Title filled from filename.** "
* Any ideas how to change this behaviour, or suggestions for a workaround? I could use the Alt field or Caption field, but I prefer using the Title field - so my client can already fill in the titles by changing the filenames before upload. | Without a post title, Attachments become significantly harder to use as they no longer have a title that can be clicked on.
If you're processing attachments and generating html manually I recommend using another piece of attachment meta, or just filling in appropriate titles, after all an image is a picture of something, let that something be its name, there's nothing stopping duplicates either.
If you really must remove the title, go to the html tab and manually remove it from the tag. Else put in a placeholder character such as '-'.
Ofnote, attachments are posts too, and that means they have post meta. **You could add a checkbox to the edit attachment page** , allowing you to toggle on and off wether the attachments title is displayed or not. | stackexchange-wordpress | {

How to automatically create a custom field when a post is published?

global $wpdb;
if(!wp_is_post_revision($post_ID)) {

}
}

Function to show only first instance of shortcode
I need to add a function to my theme to remove additional instances of a shortcode in a post.
First off I wonder if i'm approaching this wrong, but I have a theme that is drastically reformats the way a post is laid out. In the post we look for media and shortcode and then display them at the top of the page, basically stripping it from the content and placing it before the title.
The conditional statement checks for the existence of a featured image or a gallery shortcode, then prints it. The problem i'm running into is that the gallery is printed again in the the_content(). What i'd like to do is create a function to strip the shortcode after it's been printed the first time.
I'm aware of this hook remove_shortcode() but this will remove all instances of that shortcode where I only want to remove it after the first has been printed. | Add a static variable to the shortcode handler to check if the shortcode has been called already.
## Sample code
add_shortcode( 'wpse62826', 'wpse_62826_shortcode' );
function wpse_62826_shortcode()
{
static $done = FALSE;
// Nothing to do.
if ( $done )
{
return;
}
if ( is_singular() )
{
$done = TRUE;
}
return '<b>I run once on singular views!</b>';

Is there a way to insert multiple images into a post at the same time without using a gallery?
I'm trying to find a way to add multiple images to a blog post in wordpress at the same time. I want to be able to write text above and blow the images, just like a normal blog post. It takes a lot of time to add each image one at a time (especially if there are like 50 or so images in a post.)
I can do a gallery, but that doesn't allow you to write content above and below.

wp_nav_menu show 1 item only

How to use custom post type APIs, but use a different db table
We currently have a plugin that creates a new WP table, but it recreates the wheel when it comes to managing/updating data. It would be a good candidate for custom post types, but we don't want to pollute the `wp_posts` table.
**Use case:** We're creating a specific job board for a company that lists 100s of jobs, and we want to keep the tables clean for other php scripts outside of WP that will also be accessing the same data. Input and management would be handled by the standard WordPress APIs.
**Question:** I want to use WP's custom post type functionality, but use a different db table. Thoughts? Directions? Is it possible to simply tell WordPress to switch tables for a certain query?
**Related:** Difficult to read and understand, and not entirely the same: Use Custom Database with Custom Post Type | I don't think you can do this. Maybe you could use a whole new database, but it seems unlikely you could add a new table for managing a custom post type. For one thing, a custom post type is stored in the wp_posts table, but some of the data for it gets stored in the wp_postmeta table (especially any post meta fields). And if you have a taxonomy with it, that uses 3 different tables. And if your plugin needs to store any options those would be in another table.
I wouldn't worry about polluting the wp tables, it is how they are made to work. Part of its power is the extendability that is built in and easy to use.
You could maybe provide a way to remove your post type and all of its posts if you wanted to be able to completely remove it. | stackexchange-wordpress | {

Advice for a Newbie Wordpress Web Designer/ Themes?
I am digging into a freelance career and I would like to know what the best advice is out there when it comes to buying themes for clients?
What is the best practice? Themeforest? Bundles? What should be my criteria when choosing themes to develop and offer to clients? | Firstly, if you have to re-sell themes then you need to be sure that the licence permits it and that you are being open with the client, no buying a theme for $20, claiming it is your own and charging the client $1000.
You should learn how themes work and look towards developing your own to become a web designer, simply re-selling themes makes you a middle man, not a web designer.
An honest approach to this is by selling your services as technical assistance, you have your client pick a theme or you choose one based on their requirements and do the installation and set-up for them, alternatively learn how WordPress themes work and offer your services as a web designer to re-brand and modify the purchased template.
As for template sites, I like Theme Forest however there are loads of them out there however I cannot stress enough, make sure you are not breaking licence or market place usage terms or you could find yourself in trouble. | stackexchange-wordpress | {

Adding a querystring to an image URL when clicking 'insert into post'?
I have written a plugin which does some fancy stuff with GD lib when you upload an image.
Everything is working fine, however I need to get the image title and add it to the image URL (and file name of the image) when the user clicks 'insert into post', but can't find any references which could help me. | You need to use the filter `image_send_to_editor`.
add_filter('image_send_to_editor', 'wpse_62869_img_wrapper', 20, 8);
function wpse_62869_img_wrapper( $html, $id, $caption, $title, $align, $url, $size, $alt )
{
return $html;
}
These are the values of a test insert and you can use them to build your own `$html` response.
html | <a href=" src=" alt="Alt text for the image" title="escritorio" width="224" height="300" class="aligncenter size-medium wp-image-9" /></a>

Delete custom fields when deleting posts

WP_Query not looking at child category
Hi all I have a loop that shows a post on a single page and puts the first category name in the variable $cat:
$cat = $category[0]->cat_name;?>
Now after the post I have a link to show related posts based on this category:
$catPosts1 = new WP_Query(array('category_name'=> $cat, 'orderby' => 'rand', 'posts_per_page' => 1));
while ($catPosts1->have_posts()) : $catPosts1->the_post();
The problem I'm having if a Child Category is selected for the first post I.e. Under the category Phones the child category Accessories is chosen nothing is appearing in the related link area. Is there a way of making Wordpress use this child category? Thanks | You'll have to get the child or parent categories yourself and pass all the IDs as an array via the `category__in` argument of WP_Query.

Can I have two submit buttons in one form?
I want to provide 2 buttons in one form. User click either button can submit the form but do different jobs-- one button is to import checked files, another button is to create fiels. Will this confuse Wordpress? | If you're placing a button in a meta box, it is included within the FORM tags for a post. A simple answer is no, you shouldn't place a submit button in the post form. However, nstead of using a normal `input[type=submit]`, use the following:
<button type='button' name='button-name' id='button-id'>Button Text</button>'
A click won't process as a submit action, it will just click. You obviously will need to bind the click event to however you're importing your file list. If you're not using AJAX, you should. Check out this article on how to use AJAX in WordPress.
Having a submit button within the form will post to post.php and certainly will have unwanted effects, namely losing any changed data within the post form. | stackexchange-wordpress | {
