PHP - How To Create Notifications
HI all, I am building a php application and i am wanting to use notifications. At the moment i am just wanting to understand the methodology behind this. I dont necessarily have a use case for these notifications yet but i am going to base it off of the following: A user submits something to the database, another user gets a notifications that this has happened. I see the notifications being something appearing in the header bar (saying "you have a notification"...) I know that i will need to use ajax for this and JS/JQ but i am not really sure where to start with this. I have done some research and have come up a little blank. My main question at the moment is how does the submission of data to the database trigger the notification? As always and help here is appreciated. Kind Regards Adam Similar TutorialsI am going to use this script http://www.gayadesign.com/diy/snotify-easy-notifications-in-jquery/ but I wanted to know how exactly would I make it work like facebook does? What steps would I take to show the other user the notification rather than showing me, the sender it? Hello everyone, I am working on a form that is similar to a shopping cart system and I am thinking of creating a button that submits the checked value and saves them to a $_SESSION variable. And also a link that links to a cart.html that takes the values of a $_SESSION variable. I am have trouble figuring what tag/attribute should I use in order to achieve that.
Right now my code attached below submits the checked values to cart.html directly. However I want my submit button to save the checked box to a $_SESSION variable and STAY on the same page. And then I will implement a <a> to link to the cart.php.
I researched a little bit about this subject and I know it's somewhat related to ajax/jquery. I just wanted to know more about it from you guys. I appreciate your attention for reading the post and Thanks!
Below is the form that I currently have:
<form name= "finalForm" method="POST" action="cart.php"> <input type="Submit" name="finalSelected"/> <?php foreach($FinalName as $key => $item) {?> <tr> <td><input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" /> <?php echo "$FinalID[$key] & $item";?> </td> </tr> <?php } ;?>Below is the code for cart.php <?php require ('connect_db.php'); if(isset($_POST['finalSelected'])) { if(!empty($_POST['fSelected'])) { $chosen = $_POST['fSelected']; foreach ($chosen as $item) echo "aID selected: $item </br>"; $delimit = implode(", ", $chosen); print_r($delimit); } } if(isset($delimit)) { $cartSQL = "SELECT * from article where aID in ($delimit)"; $cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc)); while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH)) { $aTitle[] = $row[ 'name' ]; } } ?> <table> <?php if(isset($delimit)) { $c=0; foreach($aTitle as $item) {?> <tr> <td> <?php echo $aTitle[$c]; $c++;?> </td> </tr> <?php }}?> </table> hi, I'm currently trying to resize and create pictures and .jpg/jpeg & .gif works perfectly but .png just creates an empty 0bit image, why?! Code: [Select] $ = imagecreatefrompng(); imagecopyresampled(); imagepng(); I'm doing something like that and it - as said - works great with .jpg and gif but at png it just fucks up. :/ Hii i want to create an api of the short url site ( http://torrentz.0fees.net ).

I'm using a php $_POST variable as the name of a file that I want to create. fopen() , according to my understanding open the file if it exists or creates it if it doesn't. $Ref = $_POST['Ref']; I using each reference element of $Ref as the name of a file in a certain directory. So if $Ref[$i] exists as a file name in a certain directory, append to the file, if it doesn't create the file in that directory and write to it. Do I use the file path of the file within fopen()? fopen(./References/$Ref,a) or fopen(./References/$Ref,w)? Hey Everyone, I need to have the ability to create PDF/X1A documents.

Thank you, ayok Please i have questions on how to create a file system server. were you clients could upload files and download their files in the future. Is this professional to store the files in database When creating a PHP document we use echo ''; to wrap HTML into PHP, so why does it seem to me that people always say to create a form using PHP you must break it up by using HTML to show the form itself? Is there a way to create the form, and do all that is required using PHP and wrapping PHP around HTML to make it work? I can't imagine its impossible.
