can I do something like that? to pass arguments to my function? I already studied add_action doc but did not figure out how to do it. What the exact syntax to pass two arguments would look like. In particular how to pass text & integer arguments.
function recent_post_by_author($author,$number_of_posts) {
some commands;
}
add_action('thesis_hook_before_post','recent_post_by_author',10,'author,2')
UPDATE
it seems to me that it is done somehow through do_action but how? :-)
Yes, you can (but the documentation for it is horrible).
See here: http://frumph.net/wordpress/understanding-do_action-and-add_action/
I've wrote wordpress plugin long time ago, but I went to Wordpress Codex and I think that's possible: http://codex.wordpress.org/Function_Reference/add_action
<?php add_action( $tag, $function_to_add, $priority, $accepted_args ); ?>
I think you should pass them as an array. Look under examples "take arguments".
Bye
Basically the do_action is placed where the action should be executed, and it needs a name plus your custom parameters.
When you come to call the function using add_action, pass the name of your do_action() as your first argument, and the function name as the second. So something like:
function recent_post_by_author($author,$number_of_posts) {
some commands;
}
add_action('get_the_data','recent_post_by_author',10,'author,2');
// this is where it's executed
do_action('get_the_data',$author,$number_of_posts);
Should hopefully work.
