get_the_post_thumbnail wordpress 3.5

Question

For some reason the following isn't loaded anymore in wordpress 3.5. Does anyone know how to fix the get_the_post_thumbnail() ?

I'm using the follow code:

echo "<div class='meta_apps'>";
echo "<a href='"; the_permalink(); echo "'>";
echo "<div class=\"meta-icon\">".get_the_post_thumbnail($post->post_id, 'thumbnail', $attr)."</div>";
echo "<div class=\"meta-title\">".$post->post_title."</div>";
echo "</a>";
echo "</div>";

Answer 1

I could be mistaken, but I don't think $post->post_id works to retrieve the post's ID. I believe you want $post->ID. So that was probably your issue to begin with, though without seeing your $attr array, it's hard to say. Here's a reference for $post's properties. In this case, get_the_post_thumbnail is the more appropriate function.

In your answer you posted for yourself, you're using the_post_thumbnail incorrectly. First off, you don't need to echo it; the_post_thumbnail will output the thumbnail. Side note: Any function in WordPress that starts with the_ is almost always going to output something automatically. Second, You don't need to pass it $post->ID (again, using the wrong property). Third, the first property of the_post_thumbnail is the size, e.g. "thumbnail".

Problem solved,

                echo the_post_thumbnail($post->post_id, array('class' => 'meta_icon')); echo "</div>";

Don't use 'get_the_thumbnail' but simply use the_post_thumbnail.
