Where Is This Error Coming From Please by cbrass(m): 10:14am On Jul 13, 2015
This is the html link <li><a href="#" class="btn btn-info btn-sm" id="edit" data-toggle="modal" data-target="#modal-form" data-owner="<?php echo $op; ?>" data-edit="<?php echo $postID; ?> ">Edit Page</a></li>
This is the Jquery code $(function(){
$("#edit"wink.click(function(e) {
e.preventDefault();
var id = $(this).attr("data-edit"wink;
var usern = $(this).attr("data-owner"wink;
var dataString = 'id=' + id + '&user=' + usern;
$.ajax({
type: "POST",
url: "../config/edit.php",
data : dataString,
cache: false,
success: function(html){
alert(html);
}
});
});
});


<?php
$id = $_POST['id'];
$usern = $_POST['user'];
$sel = "SELECT * FROM page_timeline WHERE timelineID = '$id' AND user ='$usern' ";
$selt = $db->query($sel);
while($row = $selt->fetch_array())
{
echo $row = ['post'];
}

?>

from the php end am getting id,user undefined. of course i know what could have caused that but what i think is the ajax is not passing the values to the php but i dont know how that could have happened. angry

By mere looking, i cant pin point anything specifically but i have my suspicions.
If it were me, i will troubleshoot by first assigning values to the variables directly to id and usern. That is, i will just say var id = "2"; var usern = "3"; then run it again and see what gets posted to php.
If I still get undefined, I will rename the attributes in the <a> element to something like dataowner and dataedit; that is get rid of the dashes.
Another place to look into is the assignment of usern varibale in the datastring. Why not say usern=' + usern and then catch is as $usern = $_POST['usern']; in your php.
Lastly, i noticed your click event is tied to an ID. As you well know, ids are meant to be unique on a page so make sure you dont have another <a id="edit" on that page. If the <li> is returned in a loop, there is definitely more than one of it on the page and that is trouble! To avoid that tie the click event to a class.

I am almost certain one of these will.solve the problem.

Thanks alot for your concern, one thing I noticed it I removed that modal link so it doesn't have to pop up, and I.used alert() to know what's wrong I discovered that the PHP indeed recieved those information from the Ajax and I can see the id and the owner of post but when I switch back to the modal and the window pops up onclick it shows that undefined index thing again. So is that the popup is not waiting for Ajax to send the information before firing?

I dont understand.
Does the click on the linl both launch modal as well as POST the variables all at the same time?

yes

yes
I dont know why you may want to do that but I am not sure it is the right thing to do. If the modal launch is to confirm the click even, you can just implement it in such a way that the click POSTs the variables and the executes your php and if the query is successful, you echo the js that will launch the modal from php.

I thought of this too but the issue I have is the modal only fires when clicked so Which means that method may not work. I didn't write the modal script I saw it some where.if I can get one that fires on page load that your method will work

Again I dont fully understand the context but assuming you are just aiming to load the the details returned from your page_timeline table into that modal box heres how I will do it.
1. Launch the modals and
2. Load a page with the attributes as query strings into it (i named the page db-stuff.php).

I made my own modal here as you can see.

main-page.php

<html>
<head>
<style>
#shade
{
position:fixed; 
top:0; 
bottom:0; 
left:0; 
right:0; 
z-index:100; 
background:#000; 
opacity:0.5; 
display:none;
}
#modal-container
{ 
position:fixed; 
top:0; 
bottom:0; 
left:0; 
right:0; 
z-index:101; 
background:none; 
display:none;
}
.modal
{ 
background:#fff; 
border:1px solid #000; 
width: 40%;
height: 35%; 
margin: auto;
position: absolute;
top: 0; 
left: 0; 
bottom: 0; 
right: 0;
}
</style>
</head>
<body>
<div id="shade"></div>
<div id="modal-container"></div>

<li><a href="#" class="btn btn-info btn-sm" id="edit" data-toggle="modal" data-target="#modal-form" data-owner="<?php echo $op; ?>" data-edit="<?php echo $postID; ?> ">Edit Page</a></li> 


<script>
$(document).ready(function() {
$(document).on("click", "#edit", function(e) {
var id = $(this).attr("data-edit"wink;
var user = $(this).attr("data-owner"wink;
$("#shade"wink.fadeIn();
$("#modal-container"wink.fadeIn();
$("#modal-container"wink.load("db-stuff.php?id="+id+"&user="+user);
return false;
});
});
</script>
</body>
</html>


db-stuff.php

<?php
$id = $_POST['id'];
$usern = $_POST['user'];
$sel = "SELECT * FROM page_timeline WHERE timelineID = '$id' AND user ='$usern' ";
$selt = $db->query($sel);
echo '<div class="modal">';
while($row = $selt->fetch_array())
{
echo $row['post'];
}
echo '</div>';
?>

Yea, tested it ok.
Hope you added your jquery library and removed all the nairaland injected "wink"

Heres the fiddle : http://jsfiddle.net/fa6rosps

I commented out the .load(db-stuff.php) part and loaded the modal directly into the page with .html() since I cant load external file there

Thanks alot bro, I impletmented your example and some stuffs to it and it worked but I have another issue here. The edit link only picks one post-id ( posts and their ids are looped through the db and echoed on the page with the edit link right beside them) I have almost 10 posts Soviet should have 10 ids, I can't understand why the edit link only is picking one id in the loop
Re: Where Is This Error Coming From Please by cbrass(m): 10:17pm On Jul 20, 2015
Don't worry bro, have fixed it. Thanks a billion times

Glad you did it. I was going to tell you not to get rid of IDs on a loop but I believe you figured it out on your own.
