我正在登录,我希望 ajax 将每个键击发布到查询中。当登录名与数据库(mySQL)中的登录名匹配时,我希望将密码返回到父页面。这就是现在的全部。我过去曾使用 ajax 将 php 发布到数据库,但从未返回变量。我也不知道我是否传递了表单信息,谢谢!
index.php 脚本:
$(function(){
$("#inputEmail").keyup(function() {
var UsernameInput = $(this).val();
$.ajax({
type: "POST",
url: "PullUserDb.php",
data: { 'UsernameInput':UsernameInput },
dataType: "text",
success: function(data)
{
$('.body').html(data);
}
});
});
});
index.php HTML:
<div class = "HeaderLogin">
<form class="LoginForm">
<div class="control-group">
<div class="controls">
<input style = "height: 30px" type="text" id="inputEmail" placeholder="Email">
</div>
</div>
<div class="control-group">
<div class="controls">
<input style = "height: 30px" type="password" id="inputPassword" placeholder="Password">
</div>
</div>
<div class="control-group">
<div class="controls">
<button style = "width: 200px" type = "button" class="SubmitLogin">Sign in</button>
</div>
</div>
</form>
</div>
拉用户数据库.php:
<?php
//Connect to the server
$db_server = mysql_connect('localhost','root','');
if(!$db_server) die("Unable to connect to MySQL: " . mysql_error());
?>
<?php
//Connect to the database
mysql_select_db('databases')
or die("Unable to select database: " . mysql_error());
?>
<?php
$Input_Username = $_POST['UsernameInput'];
//Pull columns and store them into variables
$query_users = "Select *
FROM users
WHERE Username = '".$Input_Username."'";
$result_users = mysql_query($query_users);
if (!$result_users) die ("Database access failed: " . mysql_error());
while($row_user_fetch = mysql_fetch_array($result_users))
{
$Username = $row_users_fetch['Username'];
$Password = $row_users_fetch['Password'];
$Email = $row_users_fetch['Email'];
echo $Email;
}
?>
