Question

尝试为我的客户构建此页面以添加新产品带表格的页面 - 1）上传图像 2）添加价格和名称数据

由于某种原因，它不起作用。点击提交按钮后，没有任何反应，它在saveimage.php页面上停留

<form action="saveimage.php" enctype="multipart/form-data" method="post">

<input name="name" type="text">שם:</br>

<input name="price" type="text">מחיר:</br>
 
<input name="category" value="<?php $category ?>" type="hidden">
 
<input name="uploadedimage" type="file">

<input name="new_product" type="submit" value="Upload Image">
 
</form>

PHP页面

 <?php
include("../../dbconn.php");

    function GetImageExtension($imagetype)
   	 {
       if(empty($imagetype)) return false;
       switch($imagetype)

Answer 1

几乎没有变化。

1）更改

<input name="category" value="<?php $category ?>" type="hidden">

到

<input name="category" value="<?php echo $category; ?>" type="hidden">

2）更改（删除列名称周围的单引号'）

$query_upload="INSERT into products ('product_name','product_price','product_pic','category') VALUES ('".$product_name."', '".$product_price."', '".$image_name."', '".$category."')";

要

$query_upload = "INSERT into products (product_name,product_price,product_pic,category) VALUES ('$product_name', '$product_price', '$image_name','$category')";

3）在header("Location: upload_image_food.php?cname=$category&Message=Success");内添加move_uploaded_file，因为当它成功时，需要使用某些消息转到所需位置。这就是它显示空白的原因。

}else{

   exit("Error While uploading image on the server");
} 
else{

   header('Location: upload_image_food.php?cname='.$category.');
    }
} 
?>;

到

}else{

         exit("Error While uploading image on the server");
    }
}
else{
    header("Location: upload_image_food.php?cname=$category");
}
?>
