I have issue with my code recently: Below is my test code I have 2 file php: index.php & shop.php - Select 'shopid' (example: shop01) from index.php and send as POST method to shop.php - In shop.php : i check if has shopid from post request -> set shopid to $_SESSION['shopid'] - Now i back to index.php and select new shop (shop02) - in tab shop01 i press refresh button => shopid now is shop02
How to handle shopid for each tab browser i opened when i reload. Example: Tab1 is shop01, Tab2 is shop02, when reload Tab01 shop01 will not change.
Index.php :
<?php
session_start();
$shop = array('shop1','shop2','shop3','shop4');
?>
<html>
<body>
<div id='my-header'>
<!-- Header content goes here -->
</div>
<div id="my-content">
<form method="POST" action="shop.php" target="_blank">
<select name="shopid">
<?php
foreach($shop as $value){
echo '<option value="'.$value.'">'.$value.'</option>';
}
?>
</select>
<input type="submit" name="send">
</form>
</div>
</body>
</html>
Shop.php:
<?php
session_start();
if(isset($_POST['shopid'])){
$_SESSION['shopid'] = $_POST['shopid'];
}
$shopid = $_SESSION['shopid'] ?: 'no shop select';
?>
<!DOCTYPE html>
<html>
<head>
<title>TEST SHOP ID</title>
</head>
<body>
<?php echo $shopid; ?>
</body>
</html>
