I have a jquery function.
I also have a variable, $id_number.
If the value in variable exists:
I want the jquery function to load. This is a modal that should pop up on page start.
<? if(isset($id_number))
{ ?>
jQuery(document).ready(function(
<? }
else
{ ?>
jQuery(function($){
<? } ?>
// code
});
why is my function not loading on page start? What am i doing wrong?
This should work
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<? if(isset($id_number))
{ ?><script>
alert('dummy');
</script>
<? }
else
{ ?>
<script>
alert('data');
</script>
<? } ?>

I am trying to print some code from PHP after clicking button in JavaScript, however the code is not running and I can't see any errors.
<script type="text/javascript src="https://code.jquery.com/jquery-
3.4.1.min.js" >
$( document ).ready(function() {
<?php echo '$("button[data-id='. $transport[0]['request']['vehicleType']
. ']" ).click();'; ?>
});
</script>
...
<script type="text/JavaScript src=" https:="" code.jquery.com="" jquery
3.4.1.min.js"="">
$( document ).ready(function() {
$("button[data-id=seated]" ).click();});
</script>
Running the code in console works just fine and the button is clicked,however echoing from php the code is present without errors but not executed and the button is not clicked.
the code is not working even like this
php
<script src="https://code.jquery.com/jquery-3.4.1.min.js" > </script>
<script type="text/javascript">
$( document ).ready(function() {
<?php echo '$("button[data-id='. $transport[0]['request']['vehicleType'] . ']" ).click();'; ?>
});
</script>
js output
<script src="https://code.jquery.com/jquery-3.4.1.min.js"> </script>
<script type="text/javascript">
$( document ).ready(function() {
$("button[data-id=seated]" ).click();});
</script>
those missing quotes and slashes came from formatting my question, im new to the forum so i wasn't sure how to format the code.
<script src="https://code.jquery.com/jquery-3.4.1.min.js" > </script>
<script type="text/javascript">
$( document ).ready(function() {
setTimeout(function(){ <?php echo '$("button[data-id='. $transport[0]['request']['vehicleType'] . ']" )[0].click()' ?> }, 100)
setTimeout(function(){ <?php echo '$("input[value='. $transport[0]['request']['vehicleSpecification'] . ']")[0].click();'; ?> }, 100)
});
</script>
A small time out and ref to element 0 was enough to make it work
I have php code and jQuery/javascript. I want to make visitor counter using jQuery and php code.
Here is the php code :
<?php
$handle = fopen("counter.txt", "r");
if(!$handle){
echo "could not open the file" ;
} else {
$counter = (int ) fread($handle,20);
fclose ($handle);
$counter++;
//echo $counter;
$handle = fopen("counter.txt", "w" );
fwrite($handle,$counter) ;
fclose ($handle) ;
}
?>
and this is jQuery/javascript code :
<html>
<head>
<title>jQuery Hello World</title>
<script type="text/javascript" src="js/jquery-1.11.3.min.js"></script>
<script type="text/javascript" src="js/jquery.counter.js"></script>
<link href="js/jquery.counter-analog.css" rel="stylesheet">
</head>
<body>
<span id="custom"></span>
<script>
$('#custom').addClass('counter-analog').counter({
//direction: 'up',
interval: '1',
format: '99999'
//stop: '2012'
});
</script>
</body>
</html>
How can I combine the jQuery/javascript code into php code? This is my first time for using jQuery, and I still don't understand to use jQuery. So I need your help. :D Thank you.
This is the result:
I want to add "50" into the jQuery "00000", so the result is "00050"
You simply need to echo the counter value in the span element.
So assuming your PHP code is at the top of the file, it should look like this.
<?php
$handle = fopen("counter.txt", "r");
if(!$handle){
echo "could not open the file" ;
} else {
$counter = (int ) fread($handle,20);
fclose ($handle);
$counter++;
//echo $counter;
$handle = fopen("counter.txt", "w" );
fwrite($handle,$counter) ;
fclose ($handle) ;
}
?>

I would like to display a popup message when user is logged out, so I use
echo "<script>alert(\"You are logged out\");</script>";
But it doesn't work.
Below is my coding. Is there any logic problem in my coding?
<?php
session_start();
if(isset($_SESSION['Username']) == "admin")
{
?>
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<style type="text/css">
#import "../CSS/Style.css";
#import "../CSS/Admin.css";
</style>
<title>Admin Home Page</title>
</head>
<body>
<div class="body"></div>
<?php
if(isset($_GET['id']) == "logout")
{
session_destroy();
echo "<script>alert(\"You are logged out\");</script>";
header("Location: ..\Main.php");
}
else
{
?>
<div class="menu">
Manage Staff
</div>
<div class="menu2">
Manage Account
</div>
<div class="logout">
Logout
</div>
<?php
}
}
else
{
?>
<center>
<p style="font-size:50px; font-weight:bold">Access Denied</p>
<p style="font-size:18px">Your request for this page has been denied because of access control</p>
</center>
<?php
}
?>
</body>
</html>
The session will be destroyed and will also redirect to Main.php, just the alert() will not come out.
You're doing an echo and then writing a relocate header. If you did your relocate in the javascript (after the user clicked the alert), it would probably work the way you expect it to.
echo "<script>alert('You are logged out'); window.location.href='..\Main.php';</script>";
Also, the way that you use isset will cause problems because isset returns true or false (it checks if a value is present), rather than returning the value.
So instead of
if(isset($_SESSION['Username']) == "admin")
You need to do:
if(isset($_SESSION['Username']) && $_SESSION['Username'] == "admin")
header("Location: ..\Main.php"); tells the browser to go to another page before it even shows the page... if you want the user to see the alert, try this:
session_destroy();
echo "<script>";
echo "alert('You are logged out');";
echo "window.location = '../Main.php';"; // redirect with javascript, after page loads
echo "</script>";
use this it will solve your problem!! first change your code from
if(isset($_SESSION['Username']) == "admin")
{
to
if(!empty($_SESSION['Username']) && ($_SESSION['Username']=="admin")){
and than use following code
if(!empty($_GET['id']) && ($_GET['id']=="logout"))
{
session_destroy();?>
<script>
alert("You are logged out");
window.location.href='..\Main.php';
</script>
<?php }?>
Try,
This must work,
And remove php header, replace with the following code.
echo "<script>alert('You are logged out');
location.href='..\Main.php';
</script>";
I have a button that allows authentication from twitter, everything works properly, but the only issue is that i wish to open the login-twitter.php page on a different tab, i tried using window.open in place of header but it didn't work. can anyone tell how it can be done
<?php
ob_start();
session_start();
if (isset($_SESSION['id'])) {
header("location: u_tasks.php");
}
if (array_key_exists("login", $_GET))
{
$oauth_provider = $_GET['oauth_provider'];
if ($oauth_provider == 'twitter')
{
header("Location: login-twitter.php");
}
}
?>
<!DOCTYPE html>
<html lang="en">
<head></head>
<body>
<?
echo "<div class='col-md-9'>";
echo "<a href='?login&oauth_provider=twitter'><button style='background-color:#1dcaff; border-color:#1dcaff; color:white; height:30px; border-radius:10px;'>Go To Twitter</button></a>";
echo "</div>";
?>
</body>
</html>
i think it is helpful to you.
<button style='background-color:#1dcaff; border-color:#1dcaff; color:white; height:30px; border-radius:10px;'>Go To Twitter</button>
using header("Location:..."); can only do redirects. As far as I know, you'll have to do some amount of javascript or html to achieve your goal. Another problem is that browsers like to block automatically opened popups because 99% of the time automatic popups are used only by spammers. However, I'll show you a way to attempt to do this anyways:
<?php
$usingTwitter=0;
ob_start();
session_start();
if (isset($_SESSION['id'])) {
header("location: u_tasks.php");
}
if (array_key_exists("login", $_GET))
{
$oauth_provider = $_GET['oauth_provider'];
if ($oauth_provider == 'twitter')
{
$usingTwitter=1;
}
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<script>
<?php
if($usingTwitter){
echo "window.open('login-twitter.php');";
}
?>
<script>
</head>
<body>
<?
echo "<div class='col-md-9'>";
echo "<a href='?login&oauth_provider=twitter'><button style='background-color:#1dcaff; border-color:#1dcaff; color:white; height:30px; border-radius:10px;'>Go To Twitter</button></a>";
echo "</div>";
?>
</body>
</html>
Make sure you turn off popup blocking in your browser for this to work though!
I have two .php files. The first one ajax_testing.php looks like this:
<!DOCTYPE html>
<html>
<?php
$index_local=1;
$_SESSION['global_index'] = $index_local;
?>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
</head>
<body>
<div id="main">Who is batman? click count=<?echo $_SESSION['global_index'] ?>
<button id="detailed">LINK</button>
</div>
</body>
<script type="text/javascript" language="javascript">
$(document).ready(function() { /// Wait till page is loaded
$("button").click(function(){
<?php
$_SESSION['global_index']+=1;
?>
$('#main').load('property-detailed.php?global_index='
+ <?php echo $_SESSION['global_index']; ?>
+ ' #main', function() {});
});
}); //// End of Wait till page is loaded
</script>
</html>
Document number two is called property-detailed.php and looks like this:
<!DOCTYPE html>
<html>
<?php
$_SESSION['global_index'] = $_GET['global_index'];
?>
<head>
<script></script>
</head>
<body>
<div id="main">Who is batman? click count=<?php echo $_SESSION['global_index']; ?>
<button id="detailed">LINK</button>
</div>
</body>
<script type="text/javascript" language="javascript">
$(document).ready(function() { /// Wait til page is loaded
$("button").click(function(){
<?php
$_SESSION['global_index']+=1;
?>
$('#main').load('property-detailed.php?global_index='
+ <?echo $_SESSION['global_index'] ?>
+ ' #main', function() {});
});
}); //// End of Wait till page is loaded
</script>
</html>
I load the first page, and it has a variable, $global_index, that is set to 1 and a button with an ajax command to reload the div with the new information found on the second page.
My goal is to have the variable $global_index carry over and increment each time I press the button. Is this possible with only ajax being implemented? If so, is there a way to make it happen with only the first page? Otherwise would it just be easier to have my database keep track of this number and increment that?
In your ajax_testing.php:
<?php session_start(); ?>
<script type="text/javascript" src="jquery.js"></script>
<?php
$_SESSION['counter'] = 1;
$count = $_SESSION['counter'];
?>
<div id="main">Batman<?php echo $count; ?></div>
<button id="detailed">Link</button>
<script type="text/javascript">
$(document).ready(function(){
$(document).on('click','#detailed',function(){
var count = "<?php echo $count; ?>",
dataString = "counter=" + count;
$.ajax({
type: "POST",
url: "property-detaild.php",
data:dataString,
success:function(data){
$('#main').html(data);
console.log(data);
}
});
})
});
</script>
And in your property-detailed.php:
<?php
session_start();
$_SESSION['counter'] = $_SESSION['counter']+1;
echo $_SESSION['counter'];
?>
