解析多部分表单数据 [英] Parsing multipart form data
问题描述
我正在尝试将HTML POST版本的表单放在一起，该表单具有两个字段-文件上载和文本字段.由于表单具有用于文件上传的类型multipart/form-data，因此我无法通过普通的PHP $ _POST变量获取文本字段.那么如何使用PHP获取表单中的文本字段?
I'm trying to put together a HTML POST-ed form that has two fields--a file upload, and a text field. Since the form has a type multipart/form-data for the file upload, I can't get at the text field through the normal PHP $_POST variable. So how can I get at the text field in the form with PHP?
根据要求，下面是一些代码，基本上直接取自安德鲁:
As per requested, here's some code, basically taken directly from Andrew:
<html>
<body>
<form action="test2.php" method="post" enctype="multipart/form-data">
Name: <input type="text" name="imageName" />
Image: <input type="file" name="image" />
<input type="submit" value="submit" />
</form>
</body>
</html>
<?php
echo $_POST['imageName'];
echo "<pre>";
echo var_dump($_FILES['image']);
echo "</pre>";
?>
这是整个测试文件.如果删除该enctype，则可以获取POST版本的数据，但是当然不能获取该文件.使用enctype作为multipart/form-data时，我可以获取文件，但是从POST版本获得的数据中什么也没有.
That's the entire test file. If I remove the enctype, I can get the POST-ed data, but not the file of course. With the enctype as multipart/form-data, I can get the file, but nothing from the POST-ed data.
以下是带有enctype的输出:
Here's the output with the enctype:
array(5) {
["name"]=>
string(34) "testing.png"
["type"]=>
string(0) ""
["tmp_name"]=>
string(0) ""
["error"]=>
int(1)
["size"]=>
int(0)
}
没有:
testing
NULL
两次都输入相同的数字.
Same exact input both times.
推荐答案
文件上传通过 $_POST (假设您的HTML表单具有其method属性设置为"post").
File uploads come through $_FILES. Everything else comes through $_POST (assuming of course your HTML form had its method attribute set to "post").
