使用ajax、php和javascript在验证通过后插入数据库

这是my signUp.php我不知道这里有什么错误，它阻止我的表单值被插入数据库

<?php
$errors = array();
$data = array();


// validate the variables ======================================================
// if any of these variables don't exist, add an error to our $errors array

您知道AJAX代码中的这一点吗：url:'signUpValidation.php'，
既然你的文件是signUp.php

这需要很多代码，但是您调用signUp.php之后需要一次_（'insert_user.php'）；在它中，然后在insert_user中，您再次使用$_POST[“全名”]，即使您已经在signUp.php中验证了它。insert_user.php不应该只在数据库中进行查询吗

您正在检查insert_user.php中是否有（isset（$_POST['submit']）。您应该在signUp.php中检查它

如果不是类的话，我至少会在函数中组织代码：functionConnectToDB、FInsertUser

signUp.php：

require_once('functions.php');

if(isset($_POST['submit'])) {
    validations you have
}

if (empty($errors)) {
    fill $data array with $full_Name etc. cause you didn't do it!
    insertUser($data);
}

functions.php：

function connectDB() {
    ...
}
function insertUser($data) {
    connectDB();
    insert DB query
    ...
}

可能的值应该用单引号括起来，比如这个值（“$username”，“$password”）；在insertUser.phpWARNING中：使用错误抑制

操作符可以掩盖代码中的问题，并使调试问题变得更加复杂。这是最后的手段，只能在特殊情况下使用。可能是值应该用单引号括起来，比如这个值（“$username”，“$password”）；在insertUser.phpWARNING中：使用错误抑制
