I don’t think it’s the WordPress 4.8.1 release doing that: but, do you have Advanced Custom Fields Installed? If you do, their release 5.6.0 hides the default WordPress custom fields meta box by default. remove_wp_meta_box We added in a new setting in v5.5.13 allowing the default WP custom field metabox to be removed. Although simple, … Read more
Thanks for your code. I’ve investigated this issue further (this is not an integer formatting problem). The only solution I came up with for number fields is to monkey patch more WP JS. Here is entire code with modifications which supports any input type: add_action(‘print_media_templates’, function(){ ?> <script type=”text/html” id=”tmpl-custom-gallery-setting”> <h3>Custom Settings</h3> <label class=”setting”> <span><?php … Read more
Both usermeta.meta_value and postmeta.meta_value are stored as LONGTEXT. Here’s how the MySQL docs describe the size of a LONGTEXT data type: “A TEXT column with a maximum length of 4,294,967,295 or 4GB (232 – 1) characters. The effective maximum length is less if the value contains multi-byte characters. The effective maximum length of LONGTEXT columns … Read more
The easiest way is to add Javascript validation via the jQuery Validate plugin. Here’s the most basic walkthrough: Near your add_meta_box call, enqueue the jQuery Validate plugin as well as a JS file for your simple script: add_action(‘admin_enqueue_scripts’, ‘add_my_js’); function add_my_js(){ wp_enqueue_script(‘my_validate’, ‘path/to/jquery.validate.min.js’, array(‘jquery’)); wp_enqueue_script(‘my_script_js’, ‘path/to/my_script.js’); } Then in my_script.js include the following: jQuery().ready(function() { … Read more
From the codex for custom fields: The PostMeta information is stored in a new table, $wpdb->postmeta. This table has four fields: ‘meta_id’ – A unique id for each entry. ‘post_id’ – The ID of the post for this metadata. ‘meta_key’ – The name of the ‘key’. ‘meta_value’ – The value associated with the key. This … Read more
After adding our custom column, we are ready to expand our Post Quick Edit menu using the quick_edit_custom_box action hook. Note – The quick_edit_custom_box action hook will not fire unless there are custom columns present. That is why we started by adding a custom column. add_action(‘quick_edit_custom_box’, ‘shiba_add_quick_edit’, 10, 2); function shiba_add_quick_edit($column_name, $post_type) { if ($column_name … Read more
Thank you everyone for your help! In the end the query below got me the results I desired – which was to show and sort the posts by a custom field of “publication_date” first – sorting by the date, and if there were multiple of the same date (say, 4 marked June 2013), it would … Read more
Store errors in your class or as a global, possibly in a transient or meta, and display them in admin notices on POST requests. WP does not feature any flash message handler.
I see many people prefer to use pre_get_posts hook instead of query_posts Yay! So pre_get_posts filters a WP_Query object which means anything you could do via query_posts() you can do via $query->set() and $query->get(). In particular we can make use of the meta_query attribute (see Codex): $meta_query = array( array( ‘key’=>’featured’, ‘value’=>’yes’, ‘compare’=>’!=’, ), ); … Read more
I have been searching for hours for a solution to this problem. Array merging is not the way to go, especially when the queries are complex and you must be able to add to meta queries in the future. The solution which is simplistically beautiful is to change ‘s’ to one which allows both searching … Read more
