Question

I am facing "Notice: Undefined offset 5584" systom.log error for below code :

<?php $s_qty = 0; ?>

<tr id="item<?php echo $item->getId(); ?>">

<?php
$session_flag = 0;
if (isset($_SESSION['bluedartItemsQty'])) {
    $qtyArr = $_SESSION['bluedartItemsQty'];

    $s_qty = abs($qtyArr[$item->getId()]); // Error in this line 
    $session_flag = 1;
    $sess_qty += $s_qty;
}
?>
<input type="hidden" value="<?php if($s_qty > 0) { echo $s_qty; } else { echo $_qty; }  ?>" />

I added below code in begining , but it did't worked for me.

if( !isset($s_qty)) $s_qty = '' ;

Answer 1

Maybe add a check at the given line ...

$session_flag = 0;
if (isset($_SESSION['bluedartItemsQty'])) {
    $qtyArr = $_SESSION['bluedartItemsQty'];

    if (isset($qtyArr[$item->getId()])) { # added
        $s_qty = abs($qtyArr[$item->getId()]); // Error in this line 
        $session_flag = 1;
        $sess_qty += $s_qty;
    }
}
