How to fetch row value in PHP in Model - php

Question

I want to fetch row values of the table whenever I click on that row.
In this I have to display data of the table in row..
Whenever I click on the row I need to return other variables values of that row ..
Like When I am clicking on the subject I need to show Message of respective subject from database.
PHP Code to return row values from database.
This snippet will not run as it is PHP code(just add in the snipppet to good formatting )
In this image, Popup Model is not showing correct subject and message ..
I need this particular subject and message in the popup
<?php
include('../config/conn.php');
$sql = "SELECT * FROM helpdesk where user_id='$user_id'";
$result = $conn->query($sql);
$sr=1;
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$user_id=$row["user_id"];
$pooler_id=$row["pooler_id"];
$date=$row["date"];
$subject=$row["subject"];
$req=$row['req_id'];
$message=$row['message'];
$sql1 = "SELECT * FROM pooler where id='$pooler_id' ";
$result1 = $conn->query($sql1);
if ($result1->num_rows > 0) {
// output data of each row
while($row1 = $result1->fetch_assoc()) {
$username=$row1['user_name'];
$email=$row1['email'];
}
}
echo ' <tr>
<td>'.$sr.'</td>
<td>'.$username.'</td>
<td><a href="#" data-toggle="modal" data-target="#myModal">'.$subject.'</td>
<td>'.$date.'</td>
</tr>';
$sr++;
}
} else {
echo "0 results";
}
?>
Modal POP Code where Sender Name, Subject and Message should be displayed.
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title"> <?php echo $username; ?> <br><br> <?php echo $subject; ?> </h4>
</div>
<div class="modal-body">
<p>
<?php
echo $message;
?>
</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>

Answer 1

In your html code
<td><a href="#" data-toggle="modal" data-target="#myModal" onclick="showData('.$pooler_id.')">'.$subject.'</td>
Please pass your unique id in javascript function.
Modal
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">
<span id="user_name"><?php echo $username; ?></span> <br><br> <span id="subject"><?php echo $subject; ?></span> </h4>
</div>
<div class="modal-body">
<p id="msg">
<?php
echo $message;
?>
</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
Script
<script>
function showData(pooler_id)
{
$.ajax({
type: POST,
url : 'some_file.php',
data: {pooler_id: pooler_id},
success: function(response){
var resp = JSON.parse(response);
$('#user_name').html(resp.user_name);
$('#subject').html(resp.subject);
$('#msg').html(resp.msg);
}
});
}
</script>
In some_file.php
$pooler_id = $_POST['pooler_id'];
//get records of your primary key json_decode it
//get details from database
//this will be result fetched from database
$responseData['user_name'] = $name;
$responseData['subject'] = $subject;
$responseData['msg'] = $msg;
echo json_decode($responseData);

Answer 2

If your issue is not resolved yet and you try to avoid usage of JSON:
You could try to add an individual id (e.g. $sr) to your <div class="modal-content"> id property and <a href="#" data-toggle="modal" data-target="#myModal">'.$subject.' call in view. Got this from http://www.webdesignerdepot.com/2012/10/creating-a-modal-window-with-html5-and-css3/
Maybe this works for you.
Add to your PHP code <a href="#modal-content-'.$sr.'" data-toggle="modal" data-target="#myModal">'.$subject.':
<?php
include('../config/conn.php');
$sql = "SELECT * FROM helpdesk where user_id='$user_id'";
$result = $conn->query($sql);
$sr=1;
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$user_id=$row["user_id"];
$pooler_id=$row["pooler_id"];
$date=$row["date"];
$subject=$row["subject"];
$req=$row['req_id'];
$message=$row['message'];
$sql1 = "SELECT * FROM pooler where id='$pooler_id' ";
$result1 = $conn->query($sql1);
if ($result1->num_rows > 0) {
// output data of each row
while($row1 = $result1->fetch_assoc()) {
$username=$row1['user_name'];
$email=$row1['email']; //note this value is never used
echo ' <tr>
<td>'.$sr.'</td>
<td>'.$username.'</td>
<td>
'.$subject.'
</td>
<td>'.$date.'</td>
</tr>';
$sr++;
}
}
}
} else {
echo "0 results";
}
?>
and to your Modal <div class="modal-content-<?php echo $sr; ?>">:
<!-- Modal content -->
<div class="modal-content-<?php echo $sr; ?>">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">
<span id="user_name"><?php echo $username; ?></span> <br><br> <span id="subject"><?php echo $subject; ?></span> </h4>
</div>
<div class="modal-body">
<p id="msg"><?php echo $message; ?></p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
