Disable WordPress core fetch priority

disable-wordpress-fetch-priority.php

function disable_fetchpriority_high( $loading_attrs ) {
    unset( $loading_attrs['fetchpriority'] );
    return $loading_attrs;
}
add_filter(
    'wp_get_loading_optimization_attributes',
    'disable_fetchpriority_high'
);

I have put the code at the end of functions.php but seems this code is not working. Do you have any idea why it is not working?

@Hasan101101 Would probably have to take a look at your site. I can confirm the snippet works OK. We are using this on all of our sites. And I regularly use it on client's sites. Are you sure you don't have something else adding fetch? Products like Elementor now have an experimental feature that adds fetch (it also typically places it in on the wrong image), so I would make sure it's WordPress core. Happy to take a look if you want. Just send us a message here: https://perfmatters.io/contact/

@brianleejackson thanks for your quick response.

yes, the code is working after disabling the fetchpriority feature from the Elementor.

Actually, I was forced to remove the fetchpriority feature because the fetchpriority was getting applied on the wrong image. I couldn't find any reason. Do you know how to fix this issue? or do you have any resources?

@Hasan101101 You might be able to use this snippet. You can control the size of the image that WordPress core fetch is getting applied to.

add_filter( 'wp_min_priority_img_pixels', function( $size ) { return 1000000; } );

FYI, we have WordPress core fetch disabled on all of our sites. The way it was implanted into WordPress core is not great. That's also why we added fetch into our plugin. https://perfmatters.io/docs/fetch-priority/ This way you can target anything you want. Although I usually recommend using a preload over fetch. But it depends on the site.
