You can create a filter using the “wp_get_attachment_image_attributes” hook. Place this in your functions.php file. function filter_image_title($attr, $attachment = null){ //Find your $photographer with $attachment->ID $attr[‘title’] .= ‘ (‘ . __(‘Photographed by’, ‘foobar’) . ‘ ‘ . $photographer . ‘)’; return $attr; } add_filter(‘wp_get_attachment_image_attributes’, ‘filter_image_title’, 10, 2);
Add an array and choose one for the value. add_action(‘draft_post’, ‘add_custom_field’); function add_custom_field($post_ID) { global $wpdb; if(!wp_is_post_revision($post_ID)) { $colors = array(‘white’, ‘green’, ‘blue’); add_post_meta($post_ID, ‘random_color’, $colors[array_rand($colors, 1)], true); } }
Here is a related question that should answer yours. Basicly you want to use the pre_comment_on_post hook function custom_validate_comment() { //validate for brief and rating if( empty( $_POST[‘brief’]) || empty( $_POST[‘rating’]) ) wp_die( __(‘Error: you must fill in both the rating and the brief’) ); //make comment not required if(empy($_POST[‘comment’]){$_POST[‘comment’] == “empty_comment”;} } add_action(‘pre_comment_on_post’, ‘custom_validate_comment’); … Read more
Based on this Answer by t31os. Here, all meta boxes are being set to invisible, so simply remove from the array the ones that are meant to be visible. add_action(‘user_register’, ‘wpse_58645_set_user_metaboxes’); function wpse_58645_set_user_metaboxes( $user_id ) { update_user_meta( $user_id, ‘metaboxhidden_post’, array( ‘authordiv’, ‘categorydiv’, ‘commentstatusdiv’, ‘formatdiv’, ‘postcustom’, ‘postexcerpt’, ‘postimagediv’, ‘slugdiv’, ‘tagsdiv-post_tag’, ‘trackbacksdiv’, ) ); } For registered … Read more
Based on this comment: @ChipBennett, it’s the site’s front page, i.e. the home page. (Side note: in WordPress the home page is not the Site Front Page, but rather the Blog Posts Index. is_home() returns true on the blog posts index, and not necessarily on the site front page.

FIRST BACKUP!!!!! NEXT, BE SURE THE BACKUP IS RIGHT Now, you can use this code in PHPMyAdmin UPDATE wp_postmeta SET meta_value = REPLACE(meta_value, ‘preview’, ‘edit’) WHERE meta_key = ‘dp_video_code’ Make sure that’s the correct name of the custom field, you can check it in the wp_postmeta table.
You are abusing pre_get_posts badly with that code. With pre_get_posts the point is to alter the main query. By doing that you reduce the number of necessary queries and save some processing time, plus keep the WordPress globals— $wp_query, for example– neat for any other code that might need them. What you are doing is … Read more
You don’t have a ON for your LEFT JOIN, I guess the WHERE statement you use has to be the ON statement. You should use this query instead: $querystr = ” DELETE FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON $wpdb->postmeta.post_id = $wpdb->posts.ID WHERE $wpdb->postmeta.meta_key = ‘randomID’ AND $wpdb->postmeta.meta_value=”$randomID””; Reference here: http://dev.mysql.com/doc/refman/5.0/en/join.html
Yes! Yes you can! You can use this code to retrieve a stored option: $value = get_post_meta($post->ID,’customfieldname’,true); // where true means only return 1 custom field by this name You can use this code to save a stored option: update_post_meta($post->ID,’customfieldname’,$valuetobestored); The above code will need to be inside the post loop, though you can supply … Read more
