#8640 closed enhancement (wontfix)

2 new functions for Plugin API.

With my plugins, i use often the same action for differents Hooks.

The code is:

add_action('save_post', 'example');
add_action('publish_post', 'example');
add_action('post_syndicated_item', 'example');

Why not to create add_actions() and add_filters() ?

The result will be:

add_actions( array('save_post', 'publish_post', 'post_syndicated_item'), 'example' );

Props functions:

function add_filters($tags, $function_to_add, $priority = 10, $accepted_args = 1) {
	if ( is_array($tags) ) {
		foreach ( (array) $tags as $tag ) {
			add_filter($tag, $function_to_add, $priority, $accepted_args);
		return true;
	} else {
		return add_filter($tags, $function_to_add, $priority, $accepted_args);

function add_actions($tags, $function_to_add, $priority = 10, $accepted_args = 1) {
	return add_filters($tags, $function_to_add, $priority, $accepted_args);

same as 8640.diff, except that the filters actually get used in the default-filters.php file.

Looks handy.

Or add_filter() and add_action() could be modified to accept an array as the first argument to achieve the same thing.

#3 @DD32

There's been something before about multiple actions being passed, IIRC it was thought that modifying the existing functions to accept an array would add a overhead which wasnt really needed when you could mearly have a new function for it.

#4 @johnbillion

Ah good point DD32.

Well, I suppose it really depends, if the overhead doesn't make sense to that function.

I forget what other function it was that wanted to be added to the add_filter and add_action, but it didn't make sense at the time.

Add overhead the majority of people are not going to use will lower the limit of actions and filters that can be run before the total equals more than a second in itself.

Adding an if statement might not seem like much, but the CPU still has to make an decision on whether or not it should choose the branch that goes into the if statement or the one that ignores it. If it chooses wrong, then it has to start over.

However, making multiple function calls might be more than the overhead of the single if statement.

New functions / features usually aren't added to a minor release.

Testing and upgrading code to use new format.

#8 @ShaneF

  • Keywords commit added; dev-feedback removed

Updated orginal patch file to include the same thing for filters 'the_comment' to process many function call backs. Can not add the priority unless someone wants to take a stab at it.

Optimized current default-filters.php file to start this off.

Just need someone to confirm that this is all good! :)

#10 @jbsil

If we're going to go down this road, why not allow the function parameter to be an array of function names as well?

I.E. Change

foreach ( $filters as $filter ) { 
     add_filter($filter, 'strip_tags'); 
     add_filter($filter, 'trim'); 
     add_filter($filter, 'wp_filter_kses'); 
     add_filter($filter, 'wp_specialchars', 30); 


add_filters($filers, array('strip_tags', 'trim', 'wp_filter_kses', 'wp_specialchars'), array(null,null,null,30));

or at least

add_filters($filters, array('strip_tags', 'trim', 'wp_filter_kses'));
add_filters($filters, 'wp_specialchars', 30);

or ideally

add_filters($filters, array('strip_tags', 'trim', 'wp_filter_kses', array('wp_specialchars', 30)));

  • Milestone changed from 2.8 to 2.9

A little late for this. Will consider it early in 2.9 cycle. Shane, your 8650.2.diff patch won't work... you're not calling the new function properly. You're still passing $filter when you've removed the foreach loop.

#12 @ShaneF

D'oh! Oh well. :P

I don't think it's correct to try to something like:

add_filters($filters, array('strip_tags', 'trim', 'wp_filter_kses'));

each function can have its own priority and number of arguments, and this renders the whole idea more or less pointless. and that is not to mention the clunky looking syntax with classes (especially when they're mixed up):

add_filters($filters, array(array('foo', 'bar'), array(&$bar, 'foo'), 'foobar'));

the correct approach, I think, is the first patch, 9640.diff, which is still good against 11300.

add_filters($filters_array, $single_callback, $priority, $num_args);

#17 @Denis-de-Bernardy

itching to close as wontfix myself, as I don't find this very useful.

so please patch in 2.8, or close this. this is one of those "well, why not?" tickets that can wait for years if not committed straight away.

thank you. :-)

A subset of this ticket, for add_filter() and add_action() to accept an array of hooks, has been again proposed in #14280, this time with benchmarks.

Note: See TracTickets for help on using tickets.
