Custom HTML title based on URL parameter

Another approach that may be a bit more opaque to your users is to look at the referrer_url. This is a server-level variable that, while not 100% reliable, is generally a good indicator of where someone was when they clicked your link. It would not work if someone copied the link and sent it to … Read more

Handle multiple parameters in filter

The problem is that you use apply_filters incorrectly. This function takes at least two parameters: $tag (string) (Required) The name of the filter hook $value (mixed) (Required) The value on which the filters hooked to $tag are applied on. So the first param should be the name of the hook and as second param you … Read more

unique post in “$args” of wp_query display more than one post

I am pretty sure that the Category parameters cannot be combined with p. In the documentation it says: “Show posts associated with certain categories.” and none of the examples combine a category with a single post like you are trying to do. Instead I think you need to use a taxonomy query as such: $args … Read more

Add a class with body_class to a specific url with parameter

You’re overcomplicating it a bit. ?um_action=edit is a query string, and its values are available in the $_GET superglobal. To check if it exists, and has a specific value, you just need to do this: function leweb_add_body_class_um_edit_profile( $classes ) { if ( isset( $_GET[‘um_action’] ) && ‘edit’ === $_GET[‘um_action’] ) { $classes[] = ‘leweb-um-profile-edit’; } … Read more

Can I pass parameters to the add_shortcode() function?

You can use a closure for that together with the use keyword. Simple example: $dynamic_value = 4; add_shortcode( ‘shortcodename’, function( $attributes, $content, $shortcode_name ) use $dynamic_value { return $dynamic_value; } ); See also Passing a parameter to filter and action functions.

Passing values through url for checkbox fields with same name to get?

This really needs more context in what apple and banana are referring to and what you’re trying to accomplish and how you’ve already tried to accomplish it… You could do a custom query and set the parameters in terms based on whatever was selected in the multiple choice. This is assuming that A. fruit is … Read more

Where is this function’s callback getting its arguments from?

If you have a look at function do_meta_boxes() in wp-admin/includes/template.php then you’ll see this line close to the end of the function: call_user_func($box[‘callback’], $object, $box); That calls the callback function and provides the two arguments. The $box argument holds all the information about the metabox, like ID, title, callback function. In wp-admin/edit-form-advanced.php, which displays your … Read more

why do I have to use required parametres?

You don’t have to specify number of arguments, in which case it will default to one. Essentially this argument gives you control on how many arguments hook will pass to function, which matters in few too many situations to come up with generic explanation. In a nutshell if hook can pass N arguments, your options … Read more

How to parse a custom url (within WP site) and obtain params passed to that URL

First, you register your query vars param1 and param2: function wpse_101951_query_vars( $qv ) { $qv[] = ‘param1’; $qv[] = ‘param2’; return $qv; } add_filter( ‘query_vars’, ‘wpse_101951_query_vars’ ); To use this information, you can pretty much hook into any action or filter after parse_query. That’s the first action available after the query vars are set, so … Read more
