While/foreach不从数据库中获取值

我试图从数据库中获取一些值,但while/foreach不起作用。

<?php
$type_id = $article->type_id;
$sql = " SELECT * FROM `interior_image_testing` WHERE `type_id` = '$type_id' ";
//echo $sql;
//$result = mysqli_query($con,$sql);
if ($result = mysqli_query($con, $sql)) {


    //echo $result;
    $obj = mysqli_fetch_array($result);


    foreach ($obj as $objs):
        ?>

        <div class="col-lg-4 col-md-4 col-sm-4 col-6 workimg">
            <img src="assets/img/<?php echo $objs['image_path']; ?> " width="100%"> <!-- needs to be changed -->
        </div> 


        <?php
    endforeach;
}
?> 

问题是,我无法从数据库中获取值。 interior_testing 我有桌子 type_id , name location profile_pic interior_image_testing 我有桌子 id , image_path .

在页面上,图像未被提取。
