Post Title to featured Image ALT

Question

i saw a interesting post on Stackoverflow where someone showed a code to to use the post title als alt tag for the featured post. So i tried to use the code for myself and change it a bit because mine differs a bit.

Original Code

$title=get_the_title(); the_post_thumbnail( array(150, 150),array( 'alt' =>$title) );

I changed it to

<?php $title=get_the_title(); the_post_thumbnail( array($size),array( 'alt' =>$title) ); ?>

The problem is that $size is not working correctly anymore it came out with 150px x 150px. (My original code is <?php the_post_thumbnail( $size ); ?> )

I hope that someone could tell me what is wrong with it =o

Answer 1

If $size is already an array in your original code as it looks to be, then the argument passed will become array(array(150,150)) instead of just array(150,150) and fail, so you can just do:

<?php $title=get_the_title(); the_post_thumbnail( $size, array( 'alt' =>$title) ); ?>
