[英]Login form with JQuery ajax and php
The Goal: 目标:
Step 1: A form opens in a JQuery Dialog. 第1步:在JQuery对话框中打开一个表单。 User Enters the username and Password, Clicks on Login.
用户输入用户名和密码,点击登录。 Step 2: Ajax Sends the data to a server side script , in my case loginproc.php.
第2步: Ajax将数据发送到服务器端脚本,在我的例子中是loginproc.php。
Step 3: Validate the login using loginproc. 第3步:使用loginproc验证登录。 If the login is successful the user is redireted to a page.
如果登录成功,则用户将重定向到页面。
Step 4: Else a message is send back to the dialog and it is appended in the dialog itself along with a shake effect. 步骤4:否则将消息发送回对话框,并将其附加在对话框本身以及抖动效果中。
As of now step one and three works fine if I use '$("#admin-form").sumbit();' 截至目前,如果我使用'$(“#admin-form”),第一步和第三步工作正常.sumbit();' just before closing the dialog.
就在关闭对话框之前。 I am not sure as to how can I set the invalid login text in the diolog.
我不知道如何在diolog中设置无效的登录文本。
Code: 码:
$(function() {
var name = $("#name"),
password = $("#password"),
allFields = $([]).add(name).add(password),
tips = $(".validateTips");
function updateTips(t) {
tips
.text(t)
.addClass("ui-state-highlight");
setTimeout(function() {
tips.removeClass("ui-state-highlight", 1500);
}, 500);
}
function checkLength(o, n, min, max) {
if (o.val().length > max || o.val().length < min) {
o.addClass("ui-state-error");
updateTips("Length of " + n + " must be between " +
min + " and " + max + ".");
return false;
} else {
return true;
}
}
function checkRegexp(o, regexp, n) {
if (!(regexp.test(o.val()))) {
o.addClass("ui-state-error");
updateTips(n);
return false;
} else {
return true;
}
}
$("#login-form").dialog({
autoOpen: false,
/* height: 300, */
width: 450,
show: {
effect: "explode",
duration: 1000
},
hide: {
effect: "explode",
duration: 1000
},
modal: true,
buttons: {
"Login": function() {
var bValid = true;
allFields.removeClass("ui-state-error");
bValid = bValid && checkLength(name, "username", 3, 16);
bValid = bValid && checkLength(password, "password", 5, 32);
bValid = bValid && checkRegexp(name, /^[a-z]([0-9a-z_])+$/i, "Username may consist of a-z, 0-9, underscores, begin with a letter.");
bValid = bValid && checkRegexp(password, /^([0-9a-zA-Z_])+$/, "Password field only allow : a-z 0-9");
if (bValid) {
$("#admin_login").submit();
$(this).dialog("close");
}
},
Cancel: function() {
$(this).dialog("close");
}
},
close: function() {
allFields.val("").removeClass("ui-state-error");
}
});
// Link to open the dialog
$("#admin-link").click(function(event) {
$("#login-form").dialog("open");
event.preventDefault();
});
});
This is the section of the code in which I need to make some changes. 这是我需要进行一些更改的代码部分。
if (bValid) {
$("#admin_login").submit();
$(this).dialog("close");
}
Kindly help me figure this out 请帮我解决这个问题
UPDATE: The Form: 更新:表格:
<form method="post" action="class/loginproc.php" id="admin_login">
<fieldset>
<label for="name">Username</label>
<input type="text" name="user" id="name" class="text ui-widget-content ui-corner-all" />
<label for="password">Password</label>
<input type="password" name="pass" id="password" value="" class="text ui-widget-content ui-corner-all" />
</fieldset>
</form>
Loginproc.php Loginproc.php
<?php
require_once 'utils.php';
if (is_null($_POST['user']) || is_null($_POST['pass'])) {
utils::redirect_url("../index.php");
} else {
$utils = new utils();
$username = $_POST['user'];
$password = $_POST['pass'];
$type = 'admin';
$response = $utils->validate_user($username, $password, $type);
if ($response == true) {
return true;
/*
$utils->login_redirect($type); */
} else {
return false;
/* $_SESSION['valid'] = false;
utils::redirect_url("../index.php"); */
}
}
?>
The Jquery: Jquery:
if (bValid) {
var data = $('#admin_login').serialize();
$.ajax({
url: "class/loginproc.php",
type: "post",
data: data,
dataType: "json",
success: function(data) {
if (data.success) {
window.location = "../admin.php";
}
else {
alert('Invalid Login');
}
}
});
$(this).dialog("close");
}

我不得不改变他提供的解决方案以获得适当的结果。 Thus I am posting it here for future reference.
因此,我将其发布在此处以供将来参考。

你把方法和操作放在表单中,我认为如果使用Ajax应该省略它,因为如果不省略,数据将不会异步发送。
