Wordpress get_posts() function into Wordpress at Ionut Staicu

Wordpress get_posts() function

30 Jun

Today i spent some time trying to figure how to get existing (and also used) tags from wordpress and using in admin panel as a combo box, for my brand new theme Wordnewz.

The return of get_tags() function was some kind of array but, because of my skills (not) in PHP i spend WAY too much time to go figure what to do. The initial result of get_tags() function is:

Array
(
    [0] => stdClass Object
        (
            [term_id] => 28
            [name] => Featured
            [slug] => featured
            [term_group] => 0
            [term_taxonomy_id] => 29
            [taxonomy] => post_tag
            [description] =>
            [parent] => 0
            [count] => 6
        )
)

And i only needed [name] and [slug]. Ofcourse, like a smart guy that i am, i pointed my browser on wordpress codex where i found… NOTHING. Nothing about this function… Great. Let’s try various stuff and google it for any ideas. And i found a PHP function get_object_vars for easy conversion. After this, all was GREAT. I use it like this:

$allTags = get_tags();
foreach($allTags as $thisTags) {
		$thisTag = get_object_vars($thisTags);
		echo '<option value="'.$thisTag['slug'].'">'.$thisTag['name'].'</option>\n';
}

And it WORKS like a charm. I posted this thing because i didn’t found too much references for stdClass Object or get_tags() Wordpress function.

the reason for not finding anything about stdClass is that PHP doesn’t give an error when a class is used but not loaded, PHP uses a “STanDard Class” to deal with this kind of situations

what does this mean from a front-end development point of view? well, if you need to access/use a method (ex. function test() {}) of a class which you thought was loaded, you will receive an error because the standard class does not have the test() method

hope this helps you a bit
