我是wordpress的新手，我想要一个自定义表单，所以我创建了这个表单，用户可以从前端输入数据。但是当我提交此表单时，如果成功，则在<?php
/*
Template Name: Complain
*/
get_header();
?>
<?php
if($_POST['submit']) {
global $wpdb;
$complain_name = $_POST['complain_name'];
if($wpdb->insert(
'wp_complain',
array(
'name'=>$complain_name
)
)==false) {
echo 'Database insertion failed';
}
else {
echo 'Database insertion successful';
}
}
else {
?>
<form action="" method="POST" role="form" class="form-horizontal">
Name <input type="text" id="complain_name" class="form-control" name="complain_name" required="required" autocomplete="off"/>
<input class="btn btn-block" id="submit" type="submit" value="Submit" name="submit">
<div id="feedback"></div>
</form>
<script>
$(document).ready(function(e){
$("form").on('submit',(function(e) {
e.preventDefault();
//heresome other functions for validation
formData =new FormData(this)
$.ajax({
url:'<?php echo content_url(); ?>/themes/abc/complain-detail.php',
type: "POST",
data: formData ,
contentType: false,
cache: false,
processData:false,
success: function(data)
{
$('#feedback').html(data)
},
error: function(data)
{
$('#feedback').html(data)
}
});
}
));
})
</script>
<?php
}
get_footer();
?>
内，整个页面再次显示。因为我得到了所有＆＃34;数据＆＃34;在ajax成功或错误功能。我怎样才能获得echo中的数据？
#include "stdafx.h"
#include <iostream>
using namespace std;
int main()
{
cin;
return 0;
}

使用die("....");代替a.get_allocator() == b.get_allocator()将停止您的PHP代码，因此您的HTML将无法显示。
echo "....";答案 1 :(得分：-1)
const form = document.querySelector(".form-horizontal");
const ajax = new XMLHttpRequest();
form.addEventListener("submit",function(e){
e.preventDefault();
let data = new ForData();
data.append("complain_name",document.querySelector(".form-control").value);
ajax.open("POST",'<?php echo content_url(); ?>/themes/abc/complain-detail.php');
ajax.send(data);
if (this.readyState == 4 && this.status == 200){
document.querySelector(".feedback").textContent = "Thanks for your feedback.";
}else{
document.querySelector(".feedback").textContent = "Sorry,something when wrong,please try again later.";
}
}); <form action="" method="POST" role="form" class="form-horizontal">
Name <input type="text" id="complain_name" class="form-control" name="complain_name" required="required" autocomplete="off"/>
<input class="btn btn-block" id="submit" type="submit" value="Submit" name="submit">
<div id="feedback"></div>
</form>
