hi,
I am using the below code and want a simple print on submit event, but it is not giving any result.
Please have a look and suggest.

<?php
if(isset($_POST['submit'])){
$slno=$_POST['slno'];
echo "hello"." ".$slno;// this is to print.
}
?>

<body bgcolor="#FF0000">
<form id="registration" name="registration"  method="post" action="<?php echo $_SERVER['PHP_SELF']?>">
<?php
require_once("proconfig.php");
$query_for_result=mysqli_query($con,"SELECT * FROM album ORDER BY id ASC");
$num=mysqli_num_rows($query_for_result);
mysqli_close($con);

?>
<table >

  </tr>
</table>
         </form>

Hi rkrathor,

Your submit button is actually named save not submit, which is why your IF check isn’t working.

I prefer to use this method to check for post requests, as it’s not dependent on any specific var being submitted:


if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // …
}

PS. When posting code samples, if you wrap them in

 tags they're easier to read (especially for longer snippets).

It solved by
if(isset($_POST[‘save’])){
$slno=$_POST[‘slno’];
echo “hello”." ".$slno;// this is to print.

}
