Eliminating the appearance of a specific custom field in a post

The function, the_meta() allows you to hook to the the_meta_key filter (which currently is not documented in the Codex); this is where it fires off: // wp-includes/post-templates.php @line 744 echo apply_filters(‘the_meta_key’, “<li><span class=”post-meta-key”>$key:</span> $value</li>\n”, $key, $value); http://core.trac.wordpress.org/browser/tags/3.2.1/wp-includes/post-template.php#L735 This filter is applied to each and every meta pair, which means that you can add a filter … Read more

Orderby custom field meta value ASC and then by date DESC

Assuming the rest works, why not order the normal way: function sort_posts_orderby( $orderby ) { $orderby = ‘wp_postmeta.meta_value ASC, wp_posts.post_date DESC’; return $orderby; }

MySQL Query that looks for post with Custom Field, then changes Category

I can’t tell here whether or not you have the WordPress API available to you. (Is this code that is being run from within an instance of WordPress, or is it being run by an external script on the WordPress database, without bootstrapping WordPress itself?) If you have the WordPress API, it is easy to … Read more

Custom fields to taxonomy

You can hook into the edit form field action of that specific taxonomy. If you look in /wp-admin/edit-tag-form.php there are hooks for every taxonomy. Starting at Line 69: if ( ‘category’ == $taxonomy ) do_action(‘edit_category_form_fields’, $tag); elseif ( ‘link_category’ == $taxonomy ) do_action(‘edit_link_category_form_fields’, $tag); else do_action(‘edit_tag_form_fields’, $tag); do_action($taxonomy . ‘_edit_form_fields’, $tag, $taxonomy); So for a … Read more

load custom fields on click

I don’t know if you’ve found an answer on this question yet since it’s from 2011 but I have an idea on how to retrieve the data. What if you created a VERY simple php file that took the post ID as a get variable and displayed the post’s custom fields? It would look something … Read more

Custom Fields Not in Search Results

You can use an custom plugin for your custom fields function fb_custom_search_where($where) { // put the custom fields into an array $customs = array(‘custom_field1’, ‘custom_field2’, ‘custom_field3’); foreach( $customs as $custom ) { $query .= ” OR (“; $query .= “( m.meta_key = ‘$custom’ )”; $query .= ” AND ( m.meta_value LIKE ‘{$n}{$term}{$n}’ )”; $query .= … Read more

Saving Custom Post types and fields to a custom table

If you look at wp_insert_post()‘s source code, you can see that it’s locked to using $wpdb->posts…so you’d really need to modify the core to make it work the way you have outlined (or potentially filter it earlier up in the loop, either way, you’re making a mess). That said, having a large number of posts … Read more

How to query posts with certain custom meta data, and output Post data

Trying using WP_Query() using the meta_query arguments. Something like this: <?php $geotag_post_query_args = array( ‘meta_key’ => ‘latlng_readable’ ); $geotagged_posts = new WP_Query( $geotag_post_query_args ); ?> Now, $geotagged_posts is a query object, that should include all Posts that have the latlng_readable meta field. You can extract the $post data from this object the same as any … Read more

Passing Custom Field Data as Array to be Saved (Resulting Custom Field Array is inconsistent)

Definite solution: Seeing as wp’s core get_post_custom function returns multiple data fields saved as a single key in a random order, I resolved the issue by writing a function to replace it – which has some added flexibility: /*————————————————————— Function: Retrieve post meta field for a post based on ID Usage: [admin/meta_box/downloads.php] = to replace … Read more

Move value from one meta key to another

I hope I understand the question correctly . When you move a post , the meta keys and values associated with it should remain with the post itself, like all post meta (including the attachments , custom-image etc..) – so there should be no problem to keep the values. Normally ,The only thing that SHOULD … Read more
