First, please make sure you understand the difference between the_excerpt and the_content. You are asking about the_excerpt but I suspect that you might actually mean the_content. That said… You can filter the the_excerpt function with a filter of the same name. add_filter( ‘the_excerpt’, function ($excerpt) { return substr($excerpt,0,strpos($excerpt,’.’)+1); } );
You can approach this by first using a database query to count the number of pages that are already using the template: $query = “SELECT COUNT(*) as total FROM prefix_posts as p JOIN prefix_postmeta as m ON p.ID = m.post_id WHERE p.’post_type’ = ‘page’ AND p.’post_status’ = ‘publish’ AND m.’meta_key’ = ‘_wp_page_template’ AND m.’meta_value’ = … Read more
I took the example code from the WordPress user_has_cap filter codex page and modified it. Add this code to your theme functions.php: function restrict_editing_old_posts( $allcaps, $cap, $args ) { // Bail out if we’re not asking to edit or delete a post … if( ( ‘edit_post’ != $args[0] && ‘delete_post’ != $args[0] ) // … … Read more
I think the answer is in the source. $username = wp_strip_all_tags( $username ); $username = remove_accents( $username ); // Kill octets $username = preg_replace( ‘|%([a-fA-F0-9][a-fA-F0-9])|’, ”, $username ); $username = preg_replace( ‘/&.+?;/’, ”, $username ); // Kill entities // If strict, reduce to ASCII for max portability. if ( $strict ) $username = preg_replace( ‘|[^a-z0-9 … Read more
Some of your user pictures are 30K characters long when encoded. Have you heard of URL length limit? See What is the maximum length of a URL?. Also I believe there are some limits were put by browser manufacturers in spite of HTML 4-5 specifications does not put any limits on attribute value length (AFAIK).
We had a similar problem where we needed to give access to partners and “membership” or “subscription” plugins seemed to offer what we needed. The problem we had was that the plugins we found were all for-pay, not free or freemium. Understanding this, the MagicMembers and aMember Pro plugins both had functions that could prevent … Read more
You can use my plugin Posts Creation Limits which has a per user, per role, per post type, per post status limiting system and combined with its post_creation_limits_custom_checks action hook and check if the user has created a post that day already – if so: show the the “limit reached message”. For example: add_action( ‘post_creation_limits_custom_checks’, … Read more
I always have the same problem with post excerpt, post content. There’re various hooks and functions for this purpose, like @kaiser pointed out. But sometimes they don’t do exactly what I want. Here’s my solution, I write my own function that take the post content, and truncate it into specified number of words: function wpse69204_excerpt( … Read more
I’m not really sure which is the real problem with code you posted, however I cant understand why use 2 functions when one is enough… add_filter( ‘wp_handle_upload_prefilter’, ‘limit_uploads_for_user_roles’ ); function limit_uploads_for_user_roles( $file ) { $user = wp_get_current_user(); // add the role you want to limit in the array $limit_roles = array(‘contributor’); $filtered = apply_filters( ‘limit_uploads_for_roles’, … Read more
As you can see in the WordPress Option Reference, there’s an option called users_can_register. You can – per default – set it in your (network-)sites settings. 1 => Yes 0 => No As usual: There’s a filter to intercept that from a plugin. “option_{$option_name}” So you can simply attach a callback to this filter and … Read more
