Question

Im trying to add a little code to an already made thumbnail plugin.

Basically i want to get the image src of an image and the just print it into the HTML, but everytime i run it, its just echoing ‘Array’

This is what i have so far.

$testing = wp_get_attachment_image_src($post_thumbnail_id);
$html = '<a href="'.$testing.'">';

Any help would be greatly appreciated.

According to the WordPress Documentation for wp_get_attachment_image_src the return value is:

An array containing:
$image[0] => url
$image[1] => width
$image[2] => height

Therefore, this is what you need:

$html = '<a href="'.$testing[0].'">';
