Replacing a placeholder term with a session variable value in taxonomy filter
I have in my themes some code which will set a session variable. For the sake of example, it's a geolocation routine which will set to either USA, UK or ROW, resulting in:
$_SESSION['region'] = 'USA';
and I have a custom taxonomy of 'regionok' which any or all of the same terms are set.
I wish to use the session variable value as the taxonomy term to filter on.
The cleanest solution I can imagine would be to have a filter hook in my functions.php which would replace the placeholder term 'auto-region' with the session value before each query is executed. That way I can use widget plugins without having to hack them - I would just use the placeholder term in configuration. However, I don't know what the relevant hook would be.
(Other use cases would be session variables for family filter, referrer, etc. The geolocation example is entirely incidental.) | If you want to apply this term filter to all queries on the site, then you'll want to use the 'parse_query' action. This action will accept the WP_Query instance as a parameter, which will allow you to add a term filter based on the $_SESSION variable. | stackexchange-wordpress | {

current_page_item and custom post type?
I have a page on my site that lists all posts for my custom post type 'Literature'.
However when I click on one of the posts, the highlighted active menu item changes to 'Blog'.
How do I assign these posts to the menu item 'Literature'?

Google map iframe into wordpress theme
I have embedded a Google Map iframe in my theme and I'm trying to center a Google Map location in the middle of the map. All works fine except that my location is always shown to the upper left corner not the center

The pop up is made using javascript to center it. Happy for all suggestions, tips or answers :) | I googled some more and found out that the problem was that the `<div>` element containing the iframe was `display:none;` in my css.

Is it possible to associate different kinds of custom post types one to the other?
I might be thinking too hard about this problem and i'm thinking the solution might be easier than we're i'm heading.
Here's what i'm trying to accomplish: there a winery website built on wp and uses custom post types for "Wines" -> every wine has it's own description, picture, etc (cabarnet 2005, cabarnet 2006 etc...). Now, most wines have won medals - some of them even won up to 8 medals. i want to showcase all medal relevant to a specific wine in his specific page AND i want to have another page that showcases all medals, chronologically.
I figured i might be able to accomplish this by creating a custom post type "medal" and to somehow associate the medal to the wine that won it. but can i associate the 'medal' object in a many to one relation to the 'wine' object? how can i do that?
Any Ideas? | You can have a look at this plugin: Custom Post Types Relationships (CPTR). It lets you create relationships between posts, pages and custom posts types.

Developing mobile version of WordPress site
I would like to build a mobile version of my WordPress site. To avoid the problems and costs with developing for native platforms, I'd like to go for an HTML/CSS/jQuery approach that would be accessible from the Webkit browsers. The main site is already developed in WordPress, and content can be directly taken from the CMS.
I'd like the mobile version to be available from a specific URL such as www.mysite.com/mobile or mobile.mysite.com
How can I set this new URL to point to this version of the site? And how will this new URL change as I browse through the mobile site? And how can I load this URL by default when a user accesses the site from a mobile device?
Am I right to think that I can then develop this as I would make a normal theme for WordPress, with no other worry about this being meant for mobile devices rather than desktop? | Have a look at the WordPress Mobile Pack plugin.

Hook to get image filename when it is uploaded
I want to get the full local filename of an uploaded image so that I can copy it to a new directory and process it with my own image processing scripts. Which hooks/actions should I look into to achieve this?
Thanks | The `handle_upload` hook is called after wp_handle_upload is run, and it sends in a named array consisting of 'file', 'url' & 'type'. You could possibly use code like this to utilise it, depending on what you need to achieve:
function process_images($results) {
if( $results['type'] === 'image/jpeg' ) { // or /png or /tif / /whatever
$filename = $results[ 'file' ];
$url = $results[ 'url' ];
// manipulate the image
}
}
add_action('wp_handle_upload', 'process_images');
Edit: If you need the attachment ID as well, it might be better hooking in at a higher level, such as add / edit attachment:
add_action('add_attachment', 'process_images');
add_action('edit_attachment', 'process_images');
in which case the variable sent in is the attachment_id, from which you can derive the rest using something like:

How to prevent plugins from sniffing/stealing other plugins' options?
Many plugins require configuration with sensitive data such as API keys, passwords, etc. When implementing these plugins, this sensitive data is stored using functions such as `update_option()` and `get_option()`.
It would be trivial to write a trojan plugin that provides a useful function but also performs a variety of `get_option()` calls on known-sensitive options. Even if this isn't possible, a manual SQL query can reveal this sensitive data.
Is there any way to avoid this inherently insecure model? | Actually, there's not too much you can do.
If an intruder has direct access to your site - where they can run `get_option()` or perform direct SQL queries - then you've already run into a problem. The safest bet here is to exercise your best judgement when installing new plugins.
In other words, the best plan of action is **_prevention_**. Don't install plugins you don't recognize or written by developers you don't trust.
While you _could_ use encryption to protect the data, remember that WordPress itself still needs access. So if WP can read the data, then anyone who can run `get_option()` can also read the data. | stackexchange-wordpress | {

Get attachments by user
Is there a way to get attachments by user? I need a way to display all the images uploaded by a specific user. (I probably need the attachment IDs so that I can use `wp_get_attachment_url` to display them.) | Use a custom query for this.
$user_id = 1;
$the_query = new WP_Query( array( 'post_type' => 'attachment', 'post_status' => 'inherit', 'author' => $user_id) );
if ( $the_query->have_posts() ) while ( $the_query->have_posts() ) : $the_query->the_post();
the_title();
endwhile;

Reset positions of metaboxes in admin

How to prepend text to the_content, but after img/shortcode

Administrator: -create a place of interest \- add,delete,edit details such as place name, address, location with google map,rating(users can vote a place),latitude, longitude -add reviews for place on interest
Users: -allow users to register -contribute to site by adding a place of interest with all its details(will then be approved by the administator) -add reviews to a place of interest -up vote or downvote a place of interest | ## Short Answer
Yes. Theoretically any site can be built on top of Wordpress.
## Long Answer
You are going to need a lot of modifications to the standard Wordpress theme. But not to fret I have assembled a list of some of the things that you would need to do to get your feet wet.
1. Add _Custom Post Type_ for Places (Guide | Plugin)
2. Add _Custom Meta Boxes_ for address, latitude, longitude, etc. (Guide w/PHP Class)
3. Assign _Roles_ to users that will allow them to post. I suggest the Contributor role. If you need more control over permissions you can use the Members plugin
4. Add a WP-PostRatings plugin
5. Allow comments on posts to be used as reviews

How to get comments by post ID?
I have this custom post query to list all the posts within a specific category. For example I have this:
$args = array('cat' => 'home','post_type' => 'post'));
$post_obj = new WP_Query($args);
while($post_obj->have_posts() ) : $post_obj->the_post();
// do stuff here
endwhile;
So for this page I would like to show the list of posts but also the accompanying comments. I am only showing maximum 2 comments for each post.
Is there a built in function to do this? | You can use `get_comments`. Function Reference/get comments
$args = array('cat' => 'home','post_type' => 'post'));
$post_obj = new WP_Query($args);
while($post_obj->have_posts() ) : $post_obj->the_post();
//display comments
$comments = get_comments(array(
'post_id' => $post->ID,
'number' => '2' ));
foreach($comments as $comment) {
//format comments

What are the standard admin CSS id/class tags?
Is there a list of WordPress CSS id/classes that I can use to build plugin option screens that look and feel more like a normal WordPress option page? I have found some through serendipity but it would have been nice to have a list.
An example is this class: button-primary That makes a button look like this: !buttom-primary | We're working on updating < to have more of this information and reflect the style updates from 3.2.
Other than that, I've seen a plugin (that I currently cannot locate) that shows a demo page of sorts that displays the various CSS selectors and what they look like, but I believe it was outdated. Other than that, your best option for now may be to just fire up Firebug/Web Inspector and take a look at wp-admin/css/wp-admin.dev.css. | stackexchange-wordpress | {

Disable image resizing on specific upload fields
I am using the Options Framework Theme from devinsays, but am having a "small" problem with the Image Upload functionality. Basically, I need to disable resizing on a specific upload-field, but keep it on all others.
I do realize that this functionality is not specifically dependent on this framework, but I haven't been able to find any resource on how to achieve this on a case by case basis for specific Theme Options, so I'm hoping someone here could help.
Any input would be appreciated! | WordPress will always create the additional images for "thumbnail", "medium" and "large" sizes. The options panel doesn't add an additional size- it just resizes the one you've selected using CSS.

Advanced Permalinks plugin breaks RSS
The plugin Advanced Permalinks breaks the RSS feed since Wordpress version 3.1. The developer has stopped working on the plugin, and I haven't seen any solution for it.

Does anyone know of a way to either generate a feed differently, or of a similar plugin which could replace it? | Fixed this now, answering for anyone googling.

Wordpress ignoring specified template for front page. Why?
I'm using the Roots theme which with custom css.
I'm using the page "Home" as the front page the page "Blog" as the blog page (in WP reading settings)

handling login/logout redirects

Can't Access Sessions or Variables through pages
So I'm trying to use a session to move a variable through pages. For some reason I literally cannot access anything from index.php to archive. I declare my session at the very top of my header.php like:
<?php
if(!isset($_SESSION))
{
$_SESSION['catID'] = 3;
}
?>
Then I move to the archive.php which pulls in the header via `<?php get_header() ?>` and my session is suddenly gone. I try to echo it out and get nothing. Same thing happens with normal variables - like it's out of scope.
Anybody else have a similar problem or a solution? | In WordPress you need to start the session with
`if ( !session_id() ) { session_start(); }`

How can I redirect mobile users to diff url, but also allow them to come back to full site
this is pretty straight forward: How do I redirect mobile users to /mobile, but still allow them to click a "Full site" button and see the full site without being redirected again back to the mobile site?
I have played with a bunch of the plugins that say they do this, but none seem to handle the second step. They redirect to the /mobile . but if a user wants to go to the full site, it tries then redirects back to mobile.
I am running WP3.0.1 | function mobile_redirect() {
if (isset($_COOKIE["redirected"]) && $_COOKIE["redirected"])
return;
global $is_iphone;
if( isset($is_iphone) && $is_iphone ) {
wp_redirect( '/mobile/' );
setcookie("redirected", true);
exit;
}
}
add_action('init', 'mobile_redirect');
This code redirects every mobile visitor to /mobile/ and then sets a cookie that the user is redirected. If the cookie is set, then the redirect doesn't take place. So if the user again goes to your site it won't redirect to the mobile url.
You can also set the cookie if there is a variable in the url, like /?v=desktop, then if that url is visited it sets the cookie and doesn't redirect anymore.

UPDATE
Use of builtin $is_iphone variable; Thx to Kaiser.

How to order images in a post in Wordpress 3.3?
In wordpress 3.2 when uploading images to a post, I would get a Gallery that is linked to the post. That is, I could see in the media uploader of the post a tab that contains only the images of this post, and there would be a place to mark the order of the images I wanted for the post.
In wordpress 3.3 I can only see the media library of all the images I have ever uploaded, and I cannot order them in any way.
Is there a way to order the images related to a post? Have I somehow managed to upload the images incorrectly so that they are not attached to a post?
Any help would be appreciated. | As far as I know, media management didn't change from WP 3.2 to 3.3 (except for replacing the uploader itself with PLuploader). It has _always_ been possible to upload images directly to the media manager (by uploading via Dashboard -> Media Library ), in which case such uploaded images would not be attached to any particular post.
To test that things are working properly, go to the edit post screen for a post that you know already has attached images, and verify that the media manager still displays the menu order field for the image gallery. Then, create a new post, upload some images, and again verify that the media manager still displays the menu order field. | stackexchange-wordpress | {

What is the "proper" way to generate a javascript variable depending on a custom field value?

<script type='text/javascript'>

printf('<script type=\'text/javascript\'>
var FG_DONATE_BUTTON_PARAMS = {
attribution: \'honor\',
attribution_name: \'' . $nameAttribute .'\'
} </script>');
But I have two problems. One, the value of the $nameAttribute doesn't get passed through, and secondly, it's ugly :) I think I can manage the value problem, but I'm unsure what would be the "proper" way to output this. | You may wish to look at this question. In that question, the admin-ajax url is passed through, but it can be any variable (or array of variables), like for instance `$nameAttribute`.
For instance, you would call
wp_localize_script('my_js_file_handle','my_js_object',array('attribute'=>$nameAttribute))`
then in your js file, the variable would be accessible from my_js_object.attribute.

Pagination on 2nd loop
OK, I am creating a business listing site that is using a custom taxonomy for the listing "type". I need to display two loops on the taxonomy archive page, one for "sponsored" listings and one for regular ones.

FWIW, I've been testing the code layout here: < and it's working a bit better, in that I get the total number of "pages" it should have. But it still gives me a 404 after page 5. | The issue is that before your custom queries load, WordPress runs the main taxonomy query (all results in that tax term, 10 per page). On page 6, the main query is trying to load posts 51-60, and since they don't exist the page 404's before you have a chance to load your custom query.
Customize the main query using the pre_get_posts hook so that the second loop you're doing is the main query. Add this to functions.php: <
Then for your second loop, just do:
`if( have_posts() ): while( have_posts() ): the_post();`

Need to add class="lightbox" for every single post image
I got a theme that has lightbox built in, but only for galleries and featured images, not single images.
It just needs to have class="lightbox" added to the images source. I'd like a simple function that will include this automatically.
Not sure why the author left this out. | One way you can accomplish it is this way:
_functions.php_
add_action( 'wp_enqueue_scripts', 'your_lightbox_callback' );
function your_lightbox_callback(){
if( is_single() /* or whatever here */ ) {
wp_register_script( 'your-lightbox', get_bloginfo( 'template_url' ) . '/lightbox-class.js' );
wp_enqueue_script( 'your-lightbox' );
}
}
_lightbox-class.js_
var $j = jQuery.noConflict();
$j( document ).ready( function() {
$j( '#whereveryourpostsare img' ).addClass( 'lightbox' );
} );

how to handle forms in multiple pages?
I have a simple contact form that I set up to display on multiple pages using a shortcode and a widget but since I need to form to post back on the same were it's displayed I'm not sure how to accomplish this.
I was thinking about writing a function and plug it to the `wp_head` hook but I'm not sure if it's correct, is there a better way to do this?
Thanks in advance. | Kind of - I would suggest using `init`. This would probably be the best way of doing it since you can process the form as described below. `wp_head` would work though. Also, you should make sure you are making necessary checks with 'nonces'.
I suggest the `init` hook as you can employ something similar to 'post-redirect-get' (see here). This can help against resubmission of data when users click refresh. The usual way of doing this is to submit the url of the page along with the form, submit to a processing page, which when it's finished then redirects the user back to the original page (or a confirmation page).
Of course you don't need a separate 'processing page'. An action hooked onto `init` can check a form is submitted, check the nonces, process the form and then redirect back to the page. | stackexchange-wordpress | {

Use [shortcode="value"] instead of [shortcode att="value"]?
With shortcodes that have only one attribute, it would be much easier from a content-editing perspective to use, for example, `[icon="myicon"]` instead of `[icon whichicon="myicon"]`.
Is this possible in Wordpress? Is it problematic? | I thought this was a rather good question, so I tinkered with it a little. It seems as though the catch to using the direct method (`[icon='myicon']`) vs using an attribute is that with the direct method, you cannot use spaces as it will split to separate attributes, even if you use quotation marks, and the quotation marks and equals sign are considered part of the value. For example: a `print_r( $atts )` on `[dev_dump returns `Array ( [0] => )`, whereas a `print_r( $atts )` on `[dev_dump='my icon']` returns `Array ( [0] => ='my [1] => icon' )`. That said, however, `[dev_dump foo='bar' does give you `Array ( [foo] => bar [0] => )`, so as long as there is only ONE unlabeled value, you should be pretty safe to use that method, as you can just use $atts[0]. Be careful with setting up defaults, as I can see that becoming tricky and buggy relatively quickly.

Hook/Filter before and after comments
I'm writing a plugin that needs to display a custom link immediately near the comments. I have the option in the plugin admin to display before or after.

the_content
-- ?? custom link before ?? --
comments_array
-- ?? custom link after ?? --
comment_form | `do_action( 'comment_form_before' );` is called on line 1553 of /wp-includes/comment-template.php, right before the output of the comment form, that should handle that one for you. I'll update this if I can find the hook before the comments.

How can I display the parts of custom posts?

<?php
while ( $loop->have_posts() ) : $loop->the_post();
the_title();
echo '<div class="entry-content">';
the_content();
echo '</div>';
endwhile;

Load Next WordPress Posts With AJAX?
I found an amazing plugin that loads the next posts with Ajax.
<
However it doesn't work with custom post types.
The code looks fairly simple. Any idea how to edit the code to use custom post types?
Thanks | In principal, you could use this with _any_ archive page. All it's doing is fetching the next page of results and displaying the data.
The reason it won't work with CPTs is because of the way the PHP script is queued - with an `!is_singular()` filter.
The core of the plugin is in the JavaScript. Namely, this section:
$('.pbd-alp-placeholder-' + pageNum).load(nextLink + ' .post',
function() {
You are loading into a placeholder element the HTML contents of the "next posts" page. jQuery will fetch the page, select just the part that has a class of "post" (the `+ ' .post'` part).
You aren't doing any custom queries or lookups, just using a link WordPress generates for you by default (`next_posts()` creates a link to the next page of results).
So to make this work with CPTs you'll need to do two things:
1. Make sure the script is triggered for your custom post type archive page.
2. Make sure your CPT supports archives and pagination | stackexchange-wordpress | {

To get random posts, you can just do a `get_posts()` query with your `orderby` set to `rand` and everything else set as normal, voilà , random posts.
Same deal for most recent posts, `get_posts()`, set your `order_by` to `post_date` and your order to `DESC`...which is actually the default behavior for `get_posts()`.

2. how to "merge" DB information. | This is more a git question than a WordPress one IMHO, but what you need to do is write a bash script and associate with a git hook that does what you want. | stackexchange-wordpress | {

How do I set the default "feature image" size?
I know I can set up post, pages, and custom post types to use featured images in wordpress by enabling theme support:
add_theme_support( 'post-thumbnails');
Or enabling theme support for a specific set of post types:
add_theme_support( 'post-thumbnails', array('post','page'));
I also know that I can add an "image size" like this:
add_image_size( 'media_library', 333, 230, true );
But how do you control which image size of the "feature image" actually displays on the edit screen of Wordpress? For example in TwentyEleven I have uploaded a square photo and it shows up as a rectangle in the featured image box on the edit screen:
Picture 1.png
How do you pick which image size shows up there? | I believe that is what the `set_post_thumbnail_size` function is for.
> Set the default Post Thumbnail dimensions. To register additional image sizes for Post Thumbnails use: add_image_size().

In a loop of custom post type, display first custom taxonomy term
I would like to display just the first term from a custom post type custom taxonomy.
Inside my loop I've been displaying all the terms using:
<?php echo get_the_term_list( $post->ID, 'traits', 'Physical Traits:', ''); ?>
but I would like to only display the first term.
Thanks! | A little bit more involved but:
<?php
function get_single_term($post_id, $taxonomy)
{
$terms = wp_get_object_terms($post_id, $taxonomy);
if(!is_wp_error($terms))
{
return '<a href="'.get_term_link($terms[0]->slug, $taxonomy).'">'.$terms[0]->name.'</a>';
}
}
//example
echo get_single_term(5, 'category'); | stackexchange-wordpress | {

Modify output of custom loop using WP_query
I have a custom loop from a custom post type and I want to NOT display posts with the category 'slider'.
I'm using this to set up the query:
$args = array( 'post_type' => 'hotwives', 'posts_per_page' => -1);
$loop = new WP_Query( $args );
while ($loop->have_posts() ) : $loop->the_post();
I was going to use this in the $args variable:
'category' => 'slider'
But not sure how to make that NOT display the posts from category 'slider'.
And, incidentally, when I use that in the $args variable it still shows every post, not just the 'slider' posts. So, seems I'm not on the right track regardless.
Thanks! | $args = array(
'posts_per_page' => -1,
'post_type' => 'hotwives',
'post_status' => 'publish',
'tax_query' => array(
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => 'slider',
'operator' => 'NOT IN'
)
)
);
Use that as the args for your `WP_Query` and you should get posts that aren't in the category taxonomy. It also has the advantage of being expansible to more than one exclude, etc. If you're using a custom taxonomy, change `'taxonomy'`'s value to the name of that taxonomy.

Using categories on navigation bar instead of pages
Check this URL www.linuxstall.com. The top navigation bar has one page (about us). I want the categories there, not pages. How can I do that? | Assuming you're dealing with a recent version of Wordpress it should be pretty straightforward.
* In your Wordpress admin panel, select Appearance->Menus.
* Create a new menu. In the current wordpress there's a little plus sign at the top, enter a new menu name, and then click create menu.
* On the bottom left there should be a little widget titled Categories that has your categories. Drag categories from there to your new menu.
* Save the menu.
* In the upper left there's a Theme Locations widget that allows you to select a menu. | stackexchange-wordpress | {

Loop through child images of a parent for a Nivo Slider
I want to use a Nivo slider to cycle through the children of a parent page one by one, how can I do that?
I have the following piece of code that grabs **ALL** the children of a parent page and displays them:
<?php $pages = get_pages(array('child_of' => $post->ID));
foreach($pages as $post)
{
setup_postdata($post);
$fields = get_fields(); ?>
<?php echo $fields->title; ?>
<?php } wp_reset_query(); ?>
Is there a way to show 1 child image and upon clicking the next arrow on the Nivo it shows the next child image? | To get attached (i.e. child) images of a post, try using `get_children()`. e.g.:
<?php
$child_image_args = array(
'post_mime_type' => 'image',
'post_parent' => $postID,
'post_type' => 'attachment'
);
$child_images = get_children( $child_image_args );
?>
Which returns an associative array of child images. Then, just loop through them, e.g. using `wp_get_attachment_image()`, to output. e.g.:
<div id="nivoslider">
<?php
foreach ( $child_images as $child_image ) {
wp_get_attachment_image( $child_image->ID );
}
?>
</div>
Nivo Slider integration is mostly out of scope for WPSE, but if you want to advance manually, change the `manualAdvance` setting to `manual` in your `#nivoslider` jQuery instantiation. | stackexchange-wordpress | {

Photography Based Design - Multiple Images Per Post
I'm thinking of using WordPress for my new website.
It's a photography based website and the client will be uploading groups of photographs primarily. They'll want to give it a title and upload up to 20 photographs.
Is this possible through WordPress?
To get rid of content in the form of text and instead, opt to upload a series of Photographs?
I'm capable in WordPress, but I've not modified it much beyond vanilla previously, has anyone been able to achieve something similar? | There are many themes that focus on photography. Here are some examples:
* Gallery Theme
!Gallery Theme
* Fotofolio
!Fotofolio
... and many others - just search for photo or photography or portfolio themes. Good luck! | stackexchange-wordpress | {

Export SQL query based on post type
I'm looking to export only wp_posts where post_type = post.
Is that possible? | In your WordPress Dashboard, if you go to `Tools > Export`, you can select your custom post type and export only posts in that post type.
It gives you the option between All Content, Posts, Pages, and your custom post types following those three options.
As for SQL, well are you looking to export the data from something like phpMyAdmin? You could use this:
SELECT *
FROM `wp_posts`
WHERE `post_type` = "post type name here"
Hope this helps.
Also, as kaiser pointed out in a comment, you may need to deactivate all plugins and switch to the default theme. | stackexchange-wordpress | {
