So i have a bit of code that draws in the featured image from a post and makes it the background image for that individual post, but the issue is its just repeating same image across all posts instead of each post being its own image:
add_action( 'wp_head', 'set_featured_background', 99);
function set_featured_background() {
if ( has_post_thumbnail() ) {
$featured_img_url = get_the_post_thumbnail_url(get_the_ID(),'full');
?>
<style>
.has-post-thumbnail {
background-image: url('<?php echo $featured_img_url ?>');
background-size: 100% 100%;
}
</style>
<?php
}
}And ive tried a few different variations but it always jsut finds the most recent posts image and uses that across all posts. Do i need to be trying to put in a check to make sure it does the same thing every unique post. For example: If this post has a unique ID find its thumbnail image and apply as a style. Or is it because im trying to add it to the css class has-post-thumbnail which is applied to all posts? [that have a thumbnail]
As a note i am using Genesis grid by Bill Erickson, but it doesnt make a difference if its on or off.

Also note, you could use the wp_add_inline_style function built into WordPress for the CSS.
Based on my testing, the code you posted works, however, you can add a conditional like this :
if ( ! has_post_thumbnail() OR ! is_singular( 'post' ) ) return;
And remove one of the closing curly brackets.
Or code it like this :
if ( has_post_thumbnail() && is_singular( 'post' ) ) { return;Note : For every opening bracket, you need a closing one.
This assumes you only want to use the featured image on single posts.
Then you'll need to code the output for wp_add_inline_style. Step 2 on this tutorial will get you started.
Sorry, the 2nd line is wrong, i forgot to remove
return;Should be:
if ( has_post_thumbnail() && is_singular( 'post' ) ) {
Once again, very much appreciate the response. i will have to look into inline styling. Is there then no way of doing this without doing that then? [inline styling]
Your code will work, however there's generally more than one way to write the code.
