Have you tried using the ‘the_content’ filter? Something like this should probably do the Job , note that i have not had the time to test this . function my_prettyadd($content) { global $post; $pattern = “/(<a(?![^>]*?rel=[‘\”]prettyPhoto.*)[^>]*?href=[‘\”][^’\”]+?\.(?:bmp|gif|jpg|jpeg|png)[‘\”][^\>]*)>/i”; $replacement=”$1 rel=”prettyPhoto[“.$post->ID.’]”>’; $content = preg_replace($pattern, $replacement, $content); return $content; } add_filter(“the_content”,”my_prettyadd”); simple regex that will add a rel to … Read more

WordPress URL rewrite problem

My recommendation is to register a custom post type. You can call it products, and then all posts placed under Products will get the http://domain.com/products/some-product rewrite. Once it’s its own post type, you can specify a custom template for it, single-product.php, and you can add any custom fields, classes, etc. from there.

Problem with shortcodes in external file

Shortcodes and Tags At first, please keep in mind that your understanding of tags is actually a shortcode.

Save something to global var in add_filter

I ran a test and the following works: global $testMe; $testMe = 0; function my_acf_update_value( $value, $post_id, $field ) { global $testMe; $testMe = $value; return $value; } add_filter(‘acf/update_value/key=field_5308e5e79784b’, ‘my_acf_update_value’, 10, 3); // Test: Apply the filter apply_filters(‘acf/update_value/key=field_5308e5e79784b’,’a’,’b’,’c’); // end Test echo $testMe; // prints ‘a’ So, in principle, your code is functional. There are … Read more

Activate short codes for all post queries?

There is a way to apply that to all post content. function sc_all_content_wpse_137734($posts) { foreach ($posts as &$p) { $p->post_content = do_shortcode($p->post_content); } return $posts; } add_filter(‘the_posts’,’sc_all_content_wpse_137734′); I would suggest that this is a very, very good way to break things. Plugins and themes will not expect shortcodes to be rendered that early, and the … Read more

Custom registration field to SQL database

I have created new colums in a SQL table ‘wp_users’. Those fields are “giodo”, “handel” and “regulamin”. Don’t add columns to Core tables. There is no guarantee that these won’t be destroyed or corrupted on next update. What you should be using is user meta, and in fact that appears to be what you are … Read more

Is it possible to include the add_filter() function within a shortcode function

It should be possible but you will have to be aware of timing issues. Your shortcode will have to execute before whatever hook you are hooking into. That is, you can’t hook into wp_enqueue_scripts or wp_head but you should be able to hook into later hooks like wp_footer. I suspect that timing is the problem.

Admin filter/error if post title is too long

The key thing I think you’re missing is understanding that WordPress doesn’t use a linear path for saving posts. Because posts are autosaved you’ll want to handle this in a way that defines it according to it’s publish status rather than it’s save state. Basically, instead of trying to truncate or adjust the title, do … Read more

Can’t get content of all (19) posts – Incomplete Chunked Encoding

Ok I eventually discovered it was due to some shortcodes in a couple of the documentation articles. I escaped them with double square braces [[example]] and everything works as it should now.

Hide H1 Title using the_title filter

Depending on the way your theme uses the_title, hooking into the the_title filter may or may not hide the title h1. What theme are you using? The the_title filter passes two arguments: the title (string) and the post ID. Therefore, treating the title as an array (it looks like you’re assuming $title is an array … Read more
