I'm trying to ensure that all assets are the same size, no matter what resolution they are uploaded in. I'm stuck finding outdated info on the matter, I think.

I've gotten to the following snippet

if( get_the_post_thumbnail_url()){
    $image = wp_get_image_editor(get_the_post_thumbnail_url());
    if ( !is_wp_error( $image )){
        $image->resize( 300, 300, true );
        $image->save("image.jpg");
    }
}

Which seems to work, but I have no idea how I get the resized URL (or insert it properly). As I want to add it to my page. Something like

echo '<img src=" . $image.url() . ">";

Is what I'm thinking of. Am I going about this wrong, or how should I continue from here?

Thanks!

Why don't you use this add_image_size( 'custom-thumbnail', 300, 300, true ); in funtions.php

and call it <img src="<?php echo get_the_post_thumbnail_url('custom-thumbnail'); ?>"> in your page?

  • I tried added those two lines you mentioned. One in function.php and the other in my template. Nothing appears from that

  • I figured it out. Good tip with add_image_size that's definitely the way to go, thanks!

Maybe providing ID may help.

if( get_the_post_thumbnail_url()){
    $image = wp_get_image_editor(get_the_post_thumbnail_url(get_the_ID()));
    if ( !is_wp_error( $image )){
        $image->resize( 300, 300, true );
        $image->save("image.jpg");
    }
}

  • The issue is I don't know how to write the image to the page, it works just fine without an ID
