我想为在我的 WordPress 的不同页面上传的文件设置不同的规则，这可能吗？

到目前为止，我结束了这个，我认为这是正确的，但由于某种原因它仍然无法正常工作，如果您有时间调查并留下反馈，请。谢谢。

function up_filter( ) {
$current_url =  (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
$accURL = 'http://localhost/account/settings';
echo '<p>This is inserted at the bottom</p>';

 



if ($current_url == $accURL){ 
    
    add_filter('wp_handle_upload_prefilter','mdu_validate_image_size');
    function mdu_validate_image_size( $file ) {

    // Calculate the image size in KB
    $image_size = $file['size']/1024;
    // File size limit in KB
    $limit = 1000;

    $image = getimagesize($file['tmp_name']);
    $maximum = array(
        'width' => '120',
        'height' => '120'
    );
    $image_width = $image[0];
    $image_height = $image[1];

    $too_big = "File file size is too big. It needs to be smaller than  $limit KB. Please save photos as jpg no larger than {$maximum['width']} by {$maximum['height']} pixels.";

    $too_large = "File dimensions are too large. Maximum size is {$maximum['width']} by {$maximum['height']} pixels. Uploaded image is $image_width by $image_height pixels.";
    // Check if it's an image
    $is_image = strpos($file['type'], 'image/gif');


    if ( ( $image_size > $limit ) && ($is_image !== false) ) {
        //add in the field 'error' of the $file array the message
        $file['error'] = $too_big; 
        return $file;
    }
    elseif ( $image_width > $maximum['width'] || $image_height > $maximum['height'] ) {
        //add in the field 'error' of the $file array the message
        $file['error'] = $too_large; 
        return $file;
    }
    else
        return $file; 

}

    echo '<p>asdasd</p>';
} 
} 
add_action( 'wp', 'up_filter');
