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’
Quote from this topic about this
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.
