我有以下表格:
<form method="post" action="index.PHP"> product name: <input type="text" name="product_name" value="<?PHP echo $product_name;?>"/> <br /> <br /> product details <textarea rows = "6" cols = "30" name="product_details" > <?PHP echo $product_details;?></textarea> <br /> <br /> product price <input type="text" name = "product_price" value="<?PHP echo $product_price;?>"/> <br /> <br /> CN: <input type="text" name = "product_cn" value="<?PHP echo $product_cn;?>"/> <br /> <br /> image <input type="file" name="fileField" /> <br /> <br /> <input type="submit" name="submit" value="register product" /> </form>
我的问题是,每当我尝试使用此代码处理图像时:
move_uploaded_file($_FILES['fileField']['tmp_name'],"../product_images/$newname");
我收到以下错误:
Notice: Undefined index: fileField
这是为什么?
提前致谢!
解决方法
您必须在表单中添加enctype =’multipart / form-data’

When you make a POST request,you have to encode the data that forms the body of the request in some way.
HTML forms provide two methods of encoding. The default is application/x-www-form-urlencoded,which is more or less the same as a query string on the end of the URL. The other,multipart/form-data,is a more complicated encoding but one which allows entire files to be included in the data.
