上传默认图像未被替换 [英] Upload default image not being replaced

问题描述

i有上传功能，如果个人资料图片没有上传，我想设置默认图片



以下代码显示默认图片，但当我上传图片时，默认图片停留在那里并没有取代它吗？



我尝试过：

i have an upload feature and i wanted to set a default image if profile picture not uploaded

below code shows default image but when i upload the picture the default image stays there and doesnt replace it?

What I have tried:

$stmt = $conn->query("SELECT ProfilePicture FROM Profile WHERE UserID='$id'");
while($image =$stmt->fetch(PDO::FETCH_ASSOC)) {

echo "<img src=imgs/default.jpg width='150' height='150'/>";	
} else {
echo "<img src=uploads/".$image['Picture']."' width='150' height='150'/>"; 
}

推荐答案

id'）;
while（
