PHP不处理表格 [英] PHP doesn't process the form

问题描述

我在这里有一个小问题.
我有一个带有jQuery的表单，该表单在提交表单时禁用了提交输入.
问题是:单击输入提交时，我使用PHP处理数据.但是显然该按钮首先被禁用，然后PHP无法执行该处理.我需要找到一种方法来防止这种情况，请看一下代码片段:

I'm having a little problem here.
I have a form with a jQuery that disables the submit input when the form is submited.
The problem is: I use PHP to process the data when the input submit is clicked. But apparently the button is being disabled first, then PHP can not perform the processing. I need to find a way to prevent this, take a look in the code snippets:

<form class='send' action='{$_SERVER['PHP_SELF']}' method='post'>
    <!--Form data-->
    <input type='submit' name='finish' value='Send'/>
</form>

要禁用的jQuery函数:

jQuery function to disable:

$('.send').on('submit', function()
{
    $(this).find('input[type="submit"]').prop("disabled", true);
});

然后处理PHP代码:

if(isset($_POST['finish']))
{
    //Do things
}

正如我所说，PHP不处理表单，因为JS禁用了该按钮以防止多次提交.禁用按钮之前如何处理PHP?谢谢！

As I said, the PHP don't process the form because JS disabled the button to prevent multiple submitions. How to process PHP before disable the button? Thanks!

推荐答案

由于您禁用了提交按钮，因此它不会被发送到$_POST变量中的服务器上，因此您的代码无法正常工作说.

Since you are disabling the submit button it will not get send over to to server in the $_POST variable so your code doesn't work, as you have said.

要做的另一种方法是创建隐藏的HTML输入

Another way to do what you are looking for is to create a hidden HTML input

<input type="hidden" name="form">

然后，当您检查表单是否已发送时，您将使用

Then when you check if the form is send, you will use

if(isset($_POST['form']))
{
    //Do things
}
