question about the new function: pluggable_ui

Siguo · 2009-12-23 03:35:09

I’m learning the 4.2.0 code these days and found the new function pluggable_ui in txplib_misc.php:

function pluggable_ui($event, $element, $default=’‘)
{
………
}

It has three args.

but in txp_article.php, I find many use of this function like below:

echo pluggable_ui(‘article_ui’, ‘extend_col_1’, ‘’, $rs);

my question is:

why is there fourth arg? the function definition only use three args…..

many thanks for your help.

o, I found this in the func definition:

// string my_called_func(string $event, string $step, string $default_markup[, mixed $context_data…])

maybe someone wants a fourth arg, but drop it at last.

so the fourth arg in txp_article.php DO NOTHING.

I’m right?

The $rs is the context data that gets passed into the callback. Your callback would look like

function my_plugglable_ui_callback($event, $step, $default, $context_data='') {
// do stuff
}

in the article tab it’s the article information (sort of). The updated hak_tinymce uses pluggable_ui alot if you want to check it out. bitbucket link
