To fetch value of particular textbox - php

Question

Here, I am using session to store multiple textbox value.
But when I am going to fetch from session, I am getting the same value for all textbox which is in session.
My code:
if ($order_list) {
$i = $start +1;
foreach ($order_list as $row)
{
?>
<input type="text" name="<?php echo $row['id']; ?>" class="txt" autocomplete="off" id="txtid_<?php echo $row['id']; ?>" value="<?php if(isset($_SESSION['txtval'])) { echo $_SESSION['txtval'];} ?>">
<?php } ?>
In javascript:
$(document).on('blur','.txt',function(){
var myVar = $(this).val();
//alert(myVar);
$.ajax({
type: "GET",
url: "view_orders_checked_array.php",
data: {account: myVar, task: 'alltxt'},
async: false
});
});
In view_orders_checked_array.php :
$task = $_GET['task'];
if($task == "alltxt")
{
$_SESSION['txtval'] = $account;
}
Here, I am not getting the value of particular textbox. I am getting the value which I have last inserted.
Where I am going wrong?

Answer 1

Check below working code, if you just pass the id with your txtval and create session for each id key and value . Now when you print session array you will get all key values in session array. Please ask if difficult to understand.
Javascript
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<?php
session_start();
$_SESSION['txtval'] = '';
$order_list[0] = array('id'=>'1');
$order_list[1] = array('id'=>'2');
$order_list[2] = array('id'=>'3');
$order_list[3] = array('id'=>'4');
$start = '';
if ($order_list) {
$i = $start + 1;
foreach ($order_list as $row) {
?>
<input type="text" name="<?php echo $row['id']; ?>" class="txt" autocomplete="off"
id="txtid_<?php echo $row['id']; ?>" value="<?php if (isset($_SESSION['txtval'])) {
echo $_SESSION['txtval'];
} ?>">
<?php }
}?>
<script type="text/javascript">
$(document).on('blur','.txt',function(){
var myVar = $(this).val();
var myVarid = this.id;
$.ajax({
type: "GET",
url: "view_orders_checked_array.php",
data: {account: myVar, task: 'alltxt', id: myVarid },
async: false,
success:function(data){
console.log(data);
}
});
});
</script>
PHP file view_orders_checked_array.php
<?php
session_start();
$task = $_GET['task'];
if ($task == "alltxt") {
$_SESSION['txtval'][$_REQUEST['id']] = $_REQUEST['account'];
}
echo '<pre>';print_r($_SESSION['txtval'] );echo '</pre>';
die('Call');

Answer 2

you have to maintain array in session also so that you can do with the help of ids
var id=your loop id;
data: {account: myVar, task: 'alltxt',id:id },
and in your view_orders_checked_array page
$task = $_GET['task'];
$id=$_GET['id'];
if($task == "alltxt")
{
$_SESSION['txtval'][$id] = $account;
}
and in your code
<input type="text" name="<?php echo $row['id']; ?>" class="txt" autocomplete="off" id="txtid_<?php echo $row['id']; ?>" value="<?php if(isset($_SESSION['txtval'])) { echo $_SESSION['txtval'][$row['id']];} ?>">
i suggest you to use POST method for passing values

Answer 3

Problem is that you are putting the same value in all text fields
$_SESSION['txtval']
in your loop is always the same.
Edit
And also I think you getting same last inserted value because instead to store all text fields in array $_SESSION['txtval']['another_id_key'] you storing it in $_SESSION['txtval'] which is only one value
