PHP从Ajax请求取消链接图像不起作用

Question

I have created a script to allow to delete images from its uploaded folder and database. This script processing through AJAX request. My problem is, image is deleting from db but NOT in folder.

This is my Coding to delete images from folder -

if ($numrows == 1) {
    $stmt->bind_result($image_id, $member_id, $image);

    // define constant for upload folder
    define('UPLOAD_DIR', "images/slider/"); 

    while ($stmt->fetch()) {
        //echo UPLOAD_DIR."$member_id/$image";
        $imagePath = UPLOAD_DIR."$member_id/$image";
        echo $imagePath;

        if(file_exists($imagePath)) {
            unlink($imagePath); 
        } elseif(is_dir($image)) {
            rmdir($image); 
        }
    }               

    // Make the delete query:
    $q = 'DELETE FROM image_info WHERE image_id= ? LIMIT 1'; 
    $stmt = $mysqli->prepare($q);
    $stmt->bind_param('i', $imageId);
    $stmt->execute();

    if ($stmt->affected_rows == 1) {
        echo $successAlert;
    }   

    $stmt->close();
    unset($stmt);
}

When I echoing the $imagePath I found path is correct - images/slider/18/18_user_banner_1.jpg

I am trying hard for hours to figure this out. But Still I couldn't have any luck. Hope somebody may help me regarding this. Thank you.

You try insted of define('UPLOAD_DIR', "images/slider/"); give from your DOCUMENT_ROOT path.
ex :

define('UPLOAD_DIR', $_SERVER['DOCUMENT_ROOT']."/images/slider/");
