Re: WP Plugin – Array

[Bob]

You can use the in_array() function for that. Here’s an example:

$post_id = 1;

$posts_for_plugin = array(1,324,34);



if ( in_array($post_id, $posts_for_plugin) ) {

echo "Yep, it's in the array";

}

else	{

echo "Sorry, not in array";

}



?>

The in_array function has 2 parameters here (you can also set a third). The first parameter is the string you’re looking for in the array, which is $post_id here. The second parameter is the array in which the first parameter has to be found, here that is $posts_for_plugin. The second parameter ofcourse has to be an array.
