Question

我正在尝试使用php将一些记录添加到数据库中。我使用jquery ajax post请求传递数据。这是我的PHP代码将记录发布到数据库

<?php
session_start();
include_once 'db.php';
$data=$_POST['data'];

$data = json_decode(stripslashes($_POST['data']),true);

foreach($data as $d){

    $lname=$d['last'];

    $fname=$d['first'];

    $email=$d['email'];

    $classid=$_SESSION['classid'];

    $records = $databaseConnection->prepare('INSERT INTO  `Students` (LastName,FirstName,Email,classid,profile,confirmation)

    VALUES (:LastName,:FirstName,:Email,:classid,:profile,:confirmation)');

    //$records->bindParam(':LastName',$lname);

    //$records->bindParam(':FirstName',$fname);

    //$records->bindParam(':Email',$email);

    //$url=addcslashes('studentimg/dimg.png',"/");
$urs='test';
    //$records->bindParam(':profile',$url);

    //$records->bindParam(':classid',$classid);

    $confirmation=randomCode();

    //$records->bindParam(':confirmation',$confirmation);

    $link="www.example.com/studentpwdchange?code=$confirmation";
    echo $link;
    $records->debugDumpParams();
    $headers = "From: webmaster@example.com" . "\r\n" .
        "CC: somebodyelse@example.com";
    mail($email,"You have been added to my class","Hello You have been added to my class. Go to $link",$headers);

        $params = array(
        ':LastName' => $lname,
        ':FirstName' => $fname,
        ':Email' => $email,
        ':profile' => $link,
        ':classid' => $classid,
        ':confirmation' => $confirmation
    );
var_dump($params);
   $records->execute($params);

}



echo 'success';



function randomCode() {

    $alphabet = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890';

    $pass = array(); //remember to declare $pass as an array

    $alphaLength = strlen($alphabet) - 1; //put the length -1 in cache

    for ($i = 0; $i < 8; $i++) {

        $n = rand(0, $alphaLength);

        $pass[] = $alphabet[$n];

    }

    return implode($pass); //turn the array into a string

}

我使用jquery以下列方式传递数据

$("#stsubmit").on('click',function(){
    var data=[];
    var first=$("#first_name").val();
    var last=$("#last_name").val();
    var email=$("#email").val();
    var std={"first":first,"last":last,"email":email};
    data.push(std);
    for(i=2;i<=counter;i++)
    {
        var fn=$("#first_name"+i).val();
        var ln=$("#last_name"+i).val();
        var em=$("#email"+i).val();
        var s={"first":fn,"last":ln,"email":em};
        data.push(s);
    }
    var jsonString = JSON.stringify(data);
    $.ajax({
        url: 'tryaddstudent.php',
        data: {'data':jsonString},
        type: 'POST',
        error: function() {
            console.log('Error');
        },
        success: function(msg) {
            console.log(msg);
            //window.location.href = "standings";
        }
    });
});

我尝试了很多方法，并在stackoverflow中咨询了man的其他答案。什么都没有帮助。在控制台中，我收到以下类型的消息

[Object]
jquery.min.js:4 POST http://example.com/UML2/production/tryaddstudent.php 500 (Internal Server Error)send @ jquery.min.js:4ajax @ jquery.min.js:4(anonymous function) @ addStudents:270dispatch @ jquery.min.js:3r.handle @ jquery.min.js:3

}

addStudents:281 Internal Server Error

任何人都可以帮我解决一下。我不知道发生了什么

我的PHP脚本在XAMPP本地服务器中运行良好但在BlueHost服务器中丢失500错误
