svg icons not showing in the media library in list view

[mmjaeger]

wordpress seems to have an issue when reading/setting the metadata for an svg file - the html for the image show height/width = 1.

the following code fixes it:

<?php
// Fix WordPress 6.9 SVG dimension bug
function fix_svg_dimensions($data, $id) {
    if (get_post_mime_type($id) === 'image/svg+xml' && (!isset($data['width']) || $data['width'] <= 1)) {
        $file = get_attached_file($id);
        if ($svg = @simplexml_load_file($file)) {
            $attrs = $svg->attributes();
            if (isset($attrs->viewBox)) {
                $viewBox = preg_split('/[\s,]+/', (string)$attrs->viewBox);
                $data['width'] = (int)$viewBox[2];
                $data['height'] = (int)$viewBox[3];
            }
        }
    }
    return $data;
}
add_filter('wp_generate_attachment_metadata', 'fix_svg_dimensions', 10, 2);}}}

This was also reported 11 years ago: #26256.

Official SVG uploads support is being tracked in #24251.

Hi and welcome to WordPress Core Trac!

The one-pixel dimensions in media list view was re-reported in #37632, and the discussion about possibly editing that view should continue there.
