私はPHPスクリプトを持っていて、それをajaxで呼びたいと思っています。 "Error：email = my_email & password = myPassword"というajaxからエラーが出ました。ここで AjaxコールからPHPエラーを返す
はここでPHPスクリプト<?php
session_start(); //starts a session in order to be-able to save session variables and to read them
require "db_config.php"; //Allows us to use the database connection from db_config.php in this file
if ($_SERVER["request_method"] == "post"){ //checks if the form was submitted
$email = $_POST["email"]; //fetching the email address which was inserted in the login.html form
$password = $_POST["password"]; //fetching the password which was inserted in the login.html form
/*
querying the database, to check whether there is a result with the email and password entered by the user
*/
$checkForUser = mysqli_query($db_connection, "SELECT * FROM `tbl_users` WHERE email = '$email' and Password = '$password' LIMIT 1");
/*
checking if the query resulted in one row, if there is a row
it means there is a user with this email and password, which means these are the correct creadentials
*/
$rows = mysqli_num_rows($db_connection, $checkForUser);
if ($rows == 1){
//this means: correct credentials
//the next few lines fetch the information from the result
while($row = mysqli_fetch_assoc($checkForUser)){
$_SESSION["user_id"] = $row["userId"]; //creates a session variable containing the users id
$_SESSION["users_name"] = $row["firstName"]. " ".$row["lastName"]; //creates a session variable containing the users name
}
echo "You are now logged in: ". $_SESSION["users_name"];
}else{
//this means: incorrect credentials
echo "Incorrect Username or password"; //prints out error message
}
}
?>
であるmain.jsここ
$(document).ready(function() {
$('#loginForm').submit(function() {
var data = $(this).serialize();
$.ajax({
url: "../php/login.php",
type: "POST",
data: data,
success: function(data) {
$('*').html(data);
},
error: function() {
alert('ERROR: ' + data);
}
});
return false;
});
});

おかげで役に立つかもしれlogin.htmlページです:)
データに何が入っているのかというエラーがあるようです。あなたのURLは正しいですか？ –
@BubbleHackerどのURLですか？ –
