How do you add a custom option to user data?

To add a field to the profile/user edit page you need to use the edit_user_profile hook and show_user_profile hook so: add_action( ‘show_user_profile’, ‘my_extra_user_fields’ ); add_action( ‘edit_user_profile’, ‘my_extra_user_fields’ ); function my_extra_user_fields( $user ) { ?> <h3>User avatar</h3> <table class=”form-table”> <tr> <th><label for=”user_avatar”>User avatar</label></th> <td> <input id=”user_avatar” name=”user_avatar” type=”text” value=” <?php $user_avatar = get_the_author_meta( ‘user_avatar’, $user->ID ); … Read more

Querying custom post type with 2 custom fields (date-range)

Here is the code I ended up with that works. I should have mentioned that the query was inside the loop, because when I showed it to Damian Taggart of Mindshare Studios, he noticed that he said I should be using WP_Query instead of query_posts. Thanks to Milo and others for attempting to help me … Read more

Creating Photo Gallery System with Custom Post Type

Yes, Custom Fields is a good answer for that. To make things easier there’s a couple of plugins that can automate the process and create a nice interface for that. One is Advanced Custom Fields, but its Repeatable Field is a premium add-on, so I’ll show how to do it with another one. Custom Content … Read more

Storing meta fields multiple times OR once with multi dimensional array?

I figured I’ll leave the meta values saving on multiple fields in the db, because I’ve been doing allot of pre_get_post query filtering. Some of the features in there are for searching/filtering on post meta data and would it start making things very difficult if I was to start saving values into doubly serialized values. … Read more

Search ONLY by meta key / meta values

You could do two things: A) replace the search with a SQL query that only searches the postmeta table (faster as there’s no JOIN involved – you can get the post via it’s ID later on, when displaying the results). B) Split the string right after WHERE 1=1 and drop the later part. You can … Read more

Arrange custom fields with drag and drop?

In this example of repeatable custom fields, we can see that the following jQuery is needed: $(‘#repeatable-fieldset-one tbody’).sortable({ opacity: 0.6, revert: true, cursor: ‘move’, handle: ‘.sort’ }); And the HTML it controls is (simplified): <table id=”repeatable-fieldset-one” width=”100%”> <thead> <tr> <th width=”2%”></th> <th width=”30%”>Name</th> <th width=”60%”>URL</th> <th width=”2%”></th> </tr> </thead> <tbody> <?php if ( $repeatable_fields ) … Read more

Remove old custom field after import

As far as I know the custom key-value pairs are kept in the wp_postmeta table. You can simply examine (and delete) them in the database directly. SELECT * FROM wp_postmeta WHERE meta_key LIKE ‘%you_old_key_name%’ The ACF configuration of the fields is another story, but you say that you don’t even have the field in the … Read more

Custom field when adding new site to multisite networked WordPress

Sorry, bad news. If you look in the code-base of WP 3.9 for the responsible PHP file (which is site-new.php) you’ll unfortunately see that this is all hardcoded, like a lot of stuff in wp-admin, which IMHO totally sucks. 🙁 The only thing you can do is to build your own page for site creation … Read more

meta_query where value is equal to given value

You’re almost there — you just need to add the comparison to your meta query: $args = array( ‘post_type’ => ‘product’, ‘meta_query’ => array( array( ‘key’ => ‘artist’, ‘value’ => $artistID, ‘compare’ => ‘=’ ) ) ); https://codex.wordpress.org/Class_Reference/WP_Meta_Query Remember to filter $artistID before accepting it in your query!

Filtering a WP Query result

I solved my problem re-reading ACF’s custom fields documentation. Instead of meta_query, I should’ve used meta_key. The correct argument for a custom field is: // args $args = array( ‘numberposts’ => -1, ‘post_type’ => ‘event’, ‘meta_key’ => ‘location’, ‘meta_value’ => ‘Melbourne’ );
