在联系表格中上传表格，上传表格提交会不断提交整个表格 [英] upload form within a contact form, the upload form submit keeps submitting the whole form

问题描述

在php联系表单中有一个上传和提交按钮，但是在单击提交以进行文件上传时，此提交按钮将提交整个表单，主提交按钮也将提交整个表单。因此，用户无法上传文件。我如何确定文件提交没有提交整个表单？

推荐答案

这不起作用，因为您的代码当前包含一个表格包含在另一表格中。

This doesn't work because your code currently contains a form enclosed into another form. This is not allowed to nest forms.

您当前的代码：

<form action="contactform.php" method="post"> 
...
<form action="upload_ac.php" method="post" enctype="multipart/form-data" name="form1" id="form1">
...
</form>
...
</form>

尝试以下代码：

<form action="contactform.php" method="post" enctype="multipart/form-data" name="form1" id="form1">
Here you must add all the fields of the two previous forms.
</form>

您还必须将PHP代码从 upload_ac.php 到 contactform.php 。

You must also move the PHP code from upload_ac.php to contactform.php.

提交此新表单时，它将：

When you submit this new form, it will:

• 上传所选文件


• 填充 $ _ POST 字段的值

• upload the file you selected
• populate $_POST with the values of the fields
