I have been trying to use this code to create a modal popup that welcomes user in the WordPress dashboard when one logins with the following snippet at the functions.php or a plugin but it doesn't seem to load anything / even the thickbox.
Hope someone helps. Thanks.
add_action('admin_init', 'open_modal');
function open_modal(){
$id = get_current_user_id();
$user = get_userdata($id);
if(in_array('administrator', $user->roles)){
?>
<script>
function call_to_open_modal(){
//your code goes here...
}
call_to_open_modal();
</script>
<?php } }
Are you getting any errors in console? Try to echo your javascript inside the function :
add_action('admin_init', 'open_modal');
function open_modal(){
$id = get_current_user_id();
$user = get_userdata($id);
if(in_array('administrator', $user->roles)){
echo
"<script>
function call_to_open_modal(){
//your code goes here...
}
call_to_open_modal();
</script>";
} }

I m trying to redirect pages according to PHP session status, so that, if session start () redirect to page1 else page 2
but seems like i kinda didn't done well with coding.
code goes as:
<script>
if (session_start();) {
window.location = 'page1.php';
}
else {
window.location = 'page2.php';
}
</script>
Any Help is Appreciated..
I think u want something like this:
<script>
<?php
session_start();
if($_SESSION['login'] == true) {
$_SESSION['login'] = false;
echo "window.location = 'page1.php';";
} else {
$_SESSION['login'] = true;
echo "window.location = 'page2.php';";
}
?>
</script>
First of all, session_start is a php-related function, and you are using it inside javascript.
You should prepend and append to every PHP code you want to use both these symbols:
<?php # Start
?> # End
Second Point: If you need to redirect someone to some page, use header("location") in PHP.
So your result code should be:
<?php
if(session_start()){
header("location: page1.php");
}
else{
header("location: page2.php");
}
?>
Btw.. I don't understand why you are using a "session_start" as a condition.
// create a php file first
index.php
// include js on all pages
// create a javascript file
func.js
<script type="text/javascript">
// lets create a function
function newtab(page)
{
if(page != "")
{
window.open(page,"_self","location=yes");
}
}
</script>
<?php
// no harm, we can still add javascript here
// we assume this is index.php
// start a session here
session_start();
// you need to create a switch
if(!isset($_SESSION['switch']))
{
echo '<script>newtab("page1.php")</script>';
}
else
{
echo '<script>newtab("page2.php")</script>';
}
// you can play with the switches
?>
hope this helps
Just do it with PHP:
if(session_start()){
header("Location:page1.php"); die();
} else {
header("Location:page1.php"); die();
}
I am using Googles reCaptcha API for form validation.
I have opted to have the submit button show once the validation has been complete by using a little bit of JS.
<?php
if(isset($_POST['Login'])){
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = '6LerNA0UAAAAAEReb9rS5JXjtvNSYlMjKiocUv_O';
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
if(isset($data->success) AND $data->success==true){
//show submit button
echo '<script type=\"text/javascript\">
function myFunction() {
document.getElementById("logDiv").style.visibility="visible";
}
</script>';
}
else{ // stay hidden
'<script type=\"text/javascript\">
function myFunction() {
document.getElementById("logDiv").style.visibility="hidden";
}
</script>';
}
}
?>
<div id='logDiv' style='visibility:hidden')
<?php
echo $form->add('Login',array('type' => 'submit'));
?>
</div>
Currently, the solution isn't working; when the Captcha is validated the div remains hidden.
Is this a result of a syntax error or have a made a logical error?
What is the bug in my code?
Are there any more robust solutions?
Why not simply use a php condition to show the div? I think your JS isn´t working because you never call myFunction().
Try something like this but it will become complex over time and amount of code:
if(isset($data->success) AND $data->success==true){
$showButton = true;
}
......
if($showButton) { ?>
<div id='logDiv' style='visibility:hidden'
<?php echo $form->add('Login',array('type' => 'submit'));
?> </div> <?php }
......
Or a simple Solution:
if(is_bool($data -> success) && $data -> success){
echo '<div id="logDiv">'.$form->add('Login',array('type' => 'submit')).'</div>';
}
Echo the HTML Elements only if validition was successful otherwise simply dont ouput any HTML for the Div.
Hope this Helps.
I've written a simple login script that connects to a db, and now I want to insert a paragraph with jQuery in my #loginbox which says 'Login failed' when
if (!$row = mysqli_fetch_assoc($result))
is true.
My thought was:
[function.js]
function loginfailed() {
$('#loginbox').html("<p>Login failed.</p>");
}
[login.php]
<head>
<script type="text/javascript" src="functions.js"></script>
</head>
<?php
include '../config.php';
include 'dbh.php';
session_start();
$uid = $_POST['uid'];
$pw = $_POST['pw'];
$sql = "SELECT * FROM user WHERE uid='$uid' AND pw='$pw'";
$result = mysqli_query($conn, $sql);
if (!$row = mysqli_fetch_assoc($result))
{
header('Location: ../index.php');
echo '<script> loginfailed(); </script>';
}
else
{
header('Location: ../index.php');
}
?>
But it doesn't work.
DON'T EVER STORE PASSWORDS IN PLAIN TEXT!!
Regarding your question.
The header function redirects to index.php and does not execute the echo. One solution can be to add a $_GET parameter and after the redirect check if it exists and echo the message or append it with JS.
if (!$row = mysqli_fetch_assoc($result))
{
header('Location: ../index.php?status=fail');
}
In the index.php file at the bottom (if you want to use JS/jQuery to show message)
<script>
var status = "<?php echo (!empty($_GET['status']) && $_GET['status'] === 'fail') ? 0 : 1; ?>";
if(!status) loginfailed();
</script>
Thanks guys, but i've found my own solution with the help of Allkin.
My header now redirects to
header('Location: ../index.php?status=fail');
and my #loginbox checks if status is set and then executes my loginfailed() function.
if(isset($_GET['status'])) {
echo '<script> loginfailed(); </script>';
}
Nothing easy like that!
Thanks for your help everyone.
I want to append a PHP function that shows the user his/her IP within an inputs' placeholder. I've never seen anything like this been done before so I'd like to just see if it's possible or not.
My thoughts right now is to do something along these lines:
$('input').attr(placeholder,function(){
$('input').append('<?php $variable ?>');
});
then run the PHP code through here some how. If someone can shed some light on this I would be very grateful!
try this:
$('#inputID').attr("placeholder","<?php echo $variable; ?>");
And if you want to append to all inputs:
$(":input").attr("placeholder","<?php echo $variable; ?>");
should do the work
If you want to do it in PHP you can make a function to retrieve the IP of the user then echo the script in your page:
<?PHP
function getUserIP()
{
$client = #$_SERVER['HTTP_CLIENT_IP'];
$forward = #$_SERVER['HTTP_X_FORWARDED_FOR'];
$remote = $_SERVER['REMOTE_ADDR'];
if(filter_var($client, FILTER_VALIDATE_IP))
{
$ip = $client;
}
elseif(filter_var($forward, FILTER_VALIDATE_IP))
{
$ip = $forward;
}
else
{
$ip = $remote;
}
return $ip;
}
echo "<script type='text/javascript'>
$('input').attr(placeholder,function(){
$('input').append('".getUserIP()."');
});
</script>";
?>
I know this question is very common, I have search alot, and after alot of hard work, I am asking here.
I simply want to show an alert box and redirect it to a page.
The code below is redirecting me, but not showing me the alert box.
Please, let me know my mistake.
<?php
require_once('connection.php');
if(isset($_POST['person'])){ $name = $_POST['person']; }
if(isset($_POST['pwd'])){ $password = $_POST['pwd']; }
if(isset($_POST['position'])){ $pos = $_POST['position']; }
if(empty($name) or empty($password))
{
echo "<SCRIPT type='text/javascript'>
alert('Places should not be empty! Press Ok and try again!');
window.location.replace(\"addmember.php\");
</SCRIPT>";
}
else
{
//$query=mysqli_query($con,"insert into members (username, password,position) values ('$name','$password','$pos')");
echo "<SCRIPT type='text/javascript'>
alert('Added!');
window.location.replace(\"addmember.php\");
</SCRIPT>";
}
?>
I personally make this function to show an alert box and redirect it to a page.
function do_alert($msg,$link=NULL)
{
echo '<script type="text/javascript">
alert("' . $msg . '");
</script>';
if(!empty($link)) {
echo '<script type="text/javascript">
window.location="'.$link.'";
</script>';
}
}
Use this function both alert and redirect to a page use this
do_alert("Message","URL");
do_alert("Here this is your alert","addmember.php");
do_alert("Only your alert");
If the function 2nd parameter URL is empty then it'll only do alert.
try to change
window.location.replace(\"addmember.php\");
to
window.location='addmember.php';
