I have login page which take username and password from user after user will be login. I am getting response for successfully login. but I can not redirect to index.php.
I am getting console message that User successfully login, But then page is not redirect on other page.
My JS file is like this.
$(document).ready(function() {
//alert('ss');
$("#login-form").submit(function(e){
e.preventDefault();
var username = $("#email").val();
var password = $("#password").val();
var isValid = true;
var re = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if(!re.test($("#email").val())){
isValid = false;
$("#message").html("Please enter valid email.");
}
if($('#remember').is(':checked')){
$.cookie('adminCookie', $("#loginUser").val(), { expires: 7 });
}
else{
if($.cookie('adminCookie') == null) {
$.removeCookie("adminCookie");
}
}
if(password == ""){
isValid = false;
$("#message").html("Please enter password.");
}
if(isValid){
$.ajax({
type : "POST",
url : "process/login.php?rand="+Math.random(),
data : {
username : $("#email").val(),
password : $("#password").val(),
}
}).
done(function(response){
//alert(response);
var JSONArray = $.parseJSON(rawJSON);
console.log(response);
if(jsonObj.success=="1"){
window.location("index.php");
}else{
$("#userDiv").addClass("form-group has-error");
$("#passDiv").addClass("form-group has-error");
$("#passWarning").css("display","");
$("#passWarning").html("Invalid User Name or Password");
$.when($('#passWarning').fadeOut(5000)).done(function() {
$("#userDiv").attr('class', 'form-group');
$("#passDiv").attr('class', 'form-group');
});
}
}).fail(function(){
}).always(function() {
});
}
});
});
my PHP file is looks like this.
<?php
include "../connection.php";
extract($_POST);
$data = array();
$resArr = array();
if (isset($_POST['username']) && isset($_POST['password'])) {
$check_user = mysqli_query($conn, "select * from cut_users where email like '$username' and password like '$password' and user_role like 'A'");
if ($check_user) {
if (mysqli_num_rows($check_user) > 0) {
$message = "Login successfully.";
$success = 1;
while ($row = mysqli_fetch_array($check_user)) {
if ($row['is_active'] == "0") {
$message = "Your account is blocked. Please contact admin.";
$success = 0;
}
$data["id"] = $row['cut_users_id'];
$data["name"] = $row['name'];
$data["emailID"] = $row['email'];
$data["device"] = $row['device_type'];
$data["is_reset"] = $row['is_reset'];
$_SESSION['userID'] = $row['cut_users_id'];

$_SESSION['emailID'] = $row['email'];
}
$resArr = array("success" => $success, "data" => $data, "message" => $message);
} else {
$resArr = array("success" => 0, "data" => array(), "message" => "Email or password invalid.");
}
} else {
$resArr = array("success" => 0, "data" => array(), "message" => "Something went wrong!!!" . mysqli_error($conn));
}
} else {
$resArr = array("success" => 0, "data" => array(), "message" => "Parameter Missing");
}
header('Content-Type: application/json');
echo str_replace("\/", "/", json_encode($resArr, JSON_UNESCAPED_UNICODE));

1) Why you are using variable jsonObj instead of response ?
2) Modify your if statement like this
if(response.success==1){
window.location.href="index.php";
}
window.location is not a function it is an object. Please change href property in window.location object to redirect to new url.
window.location.href = "./index.php";
Simple redirect to specific file
if(jsonObj.success==1)
{
window.location.href = "http://www.example.com/index.php";
}

So basically I have to work on this loan calculator loancalc.000webhostapp.com
I have looked at other pages on this site "how to submit form without page reload?" but this isn't completely relevant to what i'm working on. So far i've added this into the jquery part of the page...
jQuery('qis-register').on('submit', 'input', function(){
event.preventDefault();
var name = $("input#yourname").val();
var email = $("input#youremail").val();
if (name == ""){
$("input#yourname").focus;
return false;
}
else{
}
if (email == ""){
$("input#youremail").focus;
return false;
}
});
But i'm told there is also two other scripts that I need to work with, I'm not really too experienced with php so not sure what's going on, the two php scripts I have to work with are called quick-interest-slider.php and register.php,

Do I have to edit any of the php and I also don't know what I have to write considering the php.
You can use what is called Ajax to submit the data to the server via POST.
Create a button and give it a class of qis-register, then give each of your input fields a class that matches it's name. Then just add that field to the data object that I have following the format within it.
jQuery(document).on('click', '.qis-register', function(){
var name = $("input#yourname").val();
var email = $("input#youremail").val();
if (name == ""){
$("input#yourname").focus;
}
else if (email == ""){
$("input#youremail").focus;
}
else{
jQuery.ajax({
type: "POST",
url: "your_php_here.php",
data: {
name:name,
email:email,
qissubmit:$(".qissubmit").val(),
qisapply:$(".qisapply").val(),
part2submit:$(".part2submit").val(),
},
done: function(msg){
console.log(msg);
}
});
}
});
For login i'm passing mail id and password from javascript file and i've checked through console.log that the values are printed. But when i echo both values in php only password is showed not the mail. But i can't find any error.Here i'm pasting the php file.
<?php
require_once('DBconnection.php');
ini_set('display_errors', 1);
ini_set('log_errors', 1);
$datamail = $_GET["mailID"];
$datapass = $_GET["psw"];
//$datamail = isset($_GET["mailID"]) ? $_GET["mailID"] : '';
echo $datamail;
echo $datapass;
$login_query = "SELECT * FROM student_table where mail_id = '$datamail' AND password='$datapass'";
//echo $login_query;
$login_res = $db->query($login_query);
if( $login_res->num_rows == 1 ){
//if( $login_res == true ){
echo "success";
}
else {
//echo $login_res;
echo mysqli_error($db);
exit;
}
$db->close();
?>
Javascrit file Here
function globalLogin() {

You missed an equal sign '=' in your javascript at your mailid parameter.
I am using following jQuery/Ajax method to validate a form. I am passing json data to the php file called add.php. Now If add.php page find any error its showing error message otherwise it's showing success message.
Now, In ajax success method I want to show bootstrap success message class if there is no error otherwise a error message class.
To this line :
$('#form_result').append('<p class="alert alert-danger">'+value+'</p>');
Now I can't determine how to check if the result is success.
Jquery/Ajax Code :
<script type="text/javascript">
$(document).ready(function() {
$("#add_zone").submit(function(e) {
e.preventDefault();
$.ajax({
url : 'add',
data : $(this).serialize(),
dataType : 'json',
type : 'POST',
beforeSend : function () {
$("#submit_button").val("Wait...");
},
success : function ( result ) {
$("#submit_button").val("Add New Zone");
$('#form_result').html('');
$.each( result, function( key, value ) {
if(key !== 'error') {
$('#form_result').append('<p class="alert alert-danger">'+value+'</p>');
}
});
},
});
});
});
</script>
add.php page
if(isset($_POST['form_name']) && $_POST['form_name'] == "zone") {
if(verifyForm('zone', 'add')) {
$msg = array();
$msg['error'] = false;
$zone_name = validate_data($_POST['zone_name']);
$remark = validate_data($_POST['remark']);
$errors = array();
$check = mysqli_query($conn, "SELECT zone_name FROM zone WHERE uid ='$uid' AND zone_name = '$zone_name' ");
$num_check = mysqli_num_rows($check);
if(isset($zone_name, $remark)) {
if(empty($zone_name)) {
$msg[] = 'Zone name required';
$msg['error'] = true;
} elseif($num_check > 0 ) {
$msg[] = 'Zone name already exists, choose another name';
$msg['error'] = true;
}
if(!empty($errors)) {
$msg[] = '<div class="alert alert-danger">';
$msg[] = '<strong>OPPS! Correct the following error(s):</strong><br/>';
foreach($errors as $er) {
$msg[] = $er.'.<br/>';
$msg['error'] = true;
}
$msg[] = '</div>';
}
if(empty($errors) && $msg['error'] === false) {
$insert = mysqli_query($conn, "INSERT INTO zone (zone_name, uid, remark) VALUES('$zone_name', '$uid', '$remark') ");
if($insert) {
$msg[] = 'New zone added.';
} else {
$msg[] = "Can't add new zone.";
$msg['error'] = true;
}
}
}
echo json_encode($msg);
}

I have been trying check email availibity using ajax and jquery script as follows,
my controller:
$get_result = $this->user->check_email_availablity();
if($get_result == FALSE ) {
$validate['message'] = '<p>Email is not available.</p>';
} else {
$validate['message'] = '<p>Email is available.</p>';
}
$this->load->view('user/signup', $validate);
my model:
function check_email_availablity() {
$email = $this->input->post('u_email');
$query = $this->db->query('SELECT u_email FROM tbl_users where u_email = "'.$email.'"');
if($query->num_rows() === 1) {
return FALSE;
} else {
return TRUE;
}
}
my js:
$(document).ready(function() {
/// make loader hidden in start
$('#Loading').hide();
$('#email').blur(function(){
var a = $("#email").val();
var filter = /^[a-zA-Z0-9]+[a-zA-Z0-9_.-]+[a-zA-Z0-9_-]+#[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$/;
// check if email is valid
if(filter.test(a)){
// show loader
$('#Loading').show();
$.post("<?php echo base_url()?>main/signup", {
email: $('#email').val()
},
function(response){
//#emailInfo is a span which will show you message
$('#Loading').hide();
setTimeout("finishAjax('Loading', '"+escape(response)+"')", 400);
});
return false;
}
});
function finishAjax(id, response){
$('#'+id).html(unescape(response));
$('#'+id).fadeIn();
}
});
my view:
<?php echo form_input('u_email', set_value('u_email'), 'class="form-control" id="email"'); ?>
<span id="Loading"><?php echo $message; ?></span>
My problem is model always returns TRUE and shows 'email is available' message, how do I check the email availability live
In your model change the if condition in query row:
function check_email_availablity() {
$email = $this->input->post('u_email');
$query = $this->db->query('SELECT u_email FROM tbl_users where u_email = "'.$email.'"');
if($query->num_rows() > 0) {
return FALSE;
} else {
return TRUE;
}
}
And in your controller:
$get_result = $this->user->check_email_availablity();
if(!$get_result) //if email already exist in your database
{
$validate['message'] = '<p>Email is not available.</p>';
} else {
$validate['message'] = '<p>Email is available.</p>';
}
$this->load->view('user/signup', $validate);
I created an android application using Phonegap. I made an account in 000webhost and I've added my PHP files on the server. In the phpMyAdmin, I've created my database.
Right, now I tried to connect my project with the online database and insert or check some data in it.
PROBLEM:
When I run the application in my mobile phone i get this alert from the success: ... part of code in ajax :
There is no such username.
(my PHP had in comments all the echo, except the: echo json_encode)
When I added this line (var_dump($_POST);) right after i am getting the $usernamefrom ajax in the PHP and run my app, I saw this alert: array(1){ [\"username\"]=> string(2) \"hi"\" }
When I added these lines: if (empty($username)) { echo '...' } , after I run my app, I saw that in the alert inside the error: ... part of the ajax, it is printed the echo that is inside this if. So, the $username is empty for sure.
This is my JavaScript file: (I get correctly for sure all the values from html so Focus on the two Ajax parts of code)

This is my PHP file in which I check if the username already exists (Username = Primary Key):
<?php
header('Content-type: application/json');
header('Access-Control-Allow-Origin: *');
//require_once('../database_config.php');
$server = "my***.000webhost.com";
$database = "a1****37_guideme";
$username = "a1****37_guideme";
$password = "*****";
$con = mysql_connect($server, $username, $password);
// if($con) { //echo "Connected to database!"; }
// else { //echo "Could not connect!"; }
mysql_select_db($database, $con);
$topost = file_get_contents('php://input');
$thedata = json_decode($topost, true);
$username = $thedata['username'];
//var_dump($_POST);
//if (empty($username)) {
// echo 'The username is either 0, empty, or not set at all';
//}
$sql = "SELECT COUNT(*) as Count FROM `user` WHERE `username`='$username'";
$result= mysql_query($sql, $con);
$rows = mysql_fetch_array($result);
$count = $rows['Count'];
if (!$result) {
die('Error: ' . mysql_error());
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
else {
if ($count == 0) {
echo json_encode(array('status' => 'success','message'=> 'There is no such username'));
//$response_array['status'] = 'success';
//echo json_encode($response_array);
}
else
{
echo json_encode(array('status' => 'error','message'=> 'The username already exists'));
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
}
mysql_close($con);
?>
And this is the PHP file in which I tried to insert the new entry in my database ( my credentials are for sure correct):
<?php
header('Content-type: application/json');
header('Access-Control-Allow-Origin: *');
//require_once('database_config.php');
$server = "mys****.000webhost.com";
$database = "a***37_guideme";
$username = "a***37_guideme";
$password = "******";
$con = mysql_connect($server, $username, $password);
// if($con) { //echo "Connected to database!"; }
// else { //echo "Could not connect!"; }
mysql_select_db($database, $con);
$topost = file_get_contents('php://input');
$thedata = json_decode($topost, true);
$username = $thedata['username'];
$password = $thedata['password'];
$email = $thedata['email'];
$gender = $thedata['gender'];
$age = $thedata['age'];
$about_you = $thedata['about_you'];
$sql = "INSERT INTO user (username, password, email, gender, age, about_you) ";
$sql .= "VALUES ('$username', '$password', '$email', '$gender', '$age', '$about_you')";
if (!mysql_query($sql, $con)) {
die('Error: ' . mysql_error());
// $response_array['status'] = 'error';
// echo json_encode($response_array);
}
else {
echo json_encode(array('status' => 'success','message'=> 'No problem'));
// $response_array['status'] = 'success';
// echo json_encode($response_array);
}
mysql_close($con);
?>
My problem solved by changing the way I get the data in my PHP to -> $user = $_POST['username']; instead of the way with Json (json_decode e.t.c.).
