如何让WordPress支持上传SVG格式图片并显示在媒体库中

// 只允许管理员上传SVG图片
if (current_user_can( 'manage_options' )) {
add_filter('upload_mimes', function ($mimes) {
$mimes['svg'] = 'image/svg+xml';
return $mimes;
});
}

// 媒体库列表模式显示SVG图片
add_action('admin_head', function () {
echo "<style>table.media .column-title .media-icon img[src*='.svg']{width: 100%;height: auto;}.components-responsive-wrapper__content[src*='.svg'] {position: relative;}</style>";
});

// 媒体库网格模式显示SVG图片
function zm_display_svg_media($response, $attachment, $meta){
if($response['type'] === 'image' && $response['subtype'] === 'svg+xml' && class_exists('SimpleXMLElement')){
try {
$path = get_attached_file($attachment->ID);
if(@file_exists($path)){
$svg                = new SimpleXMLElement(@file_get_contents($path));
$src                = $response['url'];
$width              = (int) $svg['width'];
$height             = (int) $svg['height'];
$response['image']  = compact( 'src', 'width', 'height' );
$response['thumb']  = compact( 'src', 'width', 'height' );
 
$response['sizes']['full'] = array(
'height'        => $height,
'width'         => $width,
'url'           => $src,
'orientation'   => $height > $width ? 'portrait' : 'landscape',
);
}
}
catch(Exception $e){}
}
return $response;
}
add_filter('wp_prepare_attachment_for_js', 'zm_display_svg_media', 10, 3);

// 媒体库网格模式显示SVG图片
function zm_svg_metadata($data, $post_id) {
$data = array(
'sizes' => array(
'large' => array(
'file' => pathinfo(wp_get_attachment_url($post_id), PATHINFO_BASENAME)
)
)
);
return $data;
}
add_filter('wp_get_attachment_metadata', 'zm_svg_metadata', 10, 2);
