PHP使用jQuery .post()提交带有多个提交按钮的表单 [英] PHP submitting a form with multiple submit buttons using jQuery .post()
问题描述
我有以下HTML代码:
I have the following HTML code:
<form method="post" action="the_file.php" id="the-form">
<input type="text" name="the_input" value="<?php if ( isset( $_POST['the_input'] ) echo $_POST['the_input]; ?>">
<button type="submit" name="eat_something" value="TRUE">Eating</button>
<button type="submit" name="eat_something" value="FALSE">Don't Eat</button>
</form>
<textarea id="result"></textarea>
此JS后面紧随其后:
$('#the-form').bind('submit', submitForm);
function submitForm(evt) {
jQuery.post(
$(this).attr('action'),
$(this).serialize(),
function(data) {
$('#result').empty().append(data).slideDown();
});
evt.preventDefault();
}
我还有一个PHP脚本，可以从提交时的输入中接收$ _POST值，并运行条件以测试单击了哪个提交按钮.
I also have a PHP script that receives the $_POST value from the input on submit and runs a conditions to test which submit button was clicked.
赞:
$input = $_POST['the_input'];
$eating = $_POST['eat_something'];
if ( $eating == 'TRUE' ) {
// Do some eating...
} else {
// Don't you dare...
}
如果我不使用jQuery.post()函数，则会发布按钮的提交值.但是，由于某种原因，我无法使用jQuery.post()函数将按钮值传递给PHP $ _POST.如果我不使用jQuery.post()，则输出不会附加到textarea上，而是以文本格式附加在单独的页面上，例如文档.我也尝试过在按钮$('button[type=submit]').bind('submit', submitForm);上调用Submit函数，但这也不能解决我的问题.
If I don't use the jQuery.post() function the submit values from the button are posted. However, for some reason, I can't manage to pass the button value to PHP $_POST with the jQuery.post() function. If I don't use jQuery.post() the output doesn't get appended to the textarea but rather in a text format on a separate page, like a document. I've also tried calling the submit function on the button $('button[type=submit]').bind('submit', submitForm); but this doesn't solve my problem either.
预先感谢您的帮助.
推荐答案
您忘记了the_name输入中的符号引号和).
You forget signle quote and ) in the_name input.
<input type="text" name="the_input" value="<?php if (isset($_POST['the_input'])) { echo $_POST['the_input'] ; } ?>">
要获取按下表单按钮的值，您需要手动添加该值以进行序列化.
and for getting form button pressed value you need to append it value manually to serialize.
$form.serialize() + "&submit="+ $('button').attr("value")
示例
<script type="text/javascript">
$(function()
{
$('button[type="submit"]').on('click',function(e)
{
e.preventDefault();
var submit_value = $(this).val();
jQuery.post
(
$(this).attr('action'),
$(this).serialize()+ "&submit="+ submit_value,
function(data)
{
$('#result').empty().append(data).slideDown();
}
);
});
});
</script>

if(isset($_POST['the_input']))
{
$input = $_POST['the_input'];
$eating = $_POST['eat_something'];
