<?php
if (isset($table1))
{
        print $table1;
}
if (isset($table2))
{
        print $table2;
}
?>

this is my whole code.
hope there is fix for this , i have looked all posts but no similar problem.

Answer 1

$_POST values are only available on the page immediately following form submission.

An easy way to keep user input through multiple pages is to pass it as hidden form fields.

So you would add a hidden form field to your ‘dets’ forms:

<input type="hidden" name="menucompare" value="'. $menucompare.'" />

Also, you’ll have to get rid of the ‘else’ on line 37

else if (isset($_POST["data"]))

to

if (isset($_POST["data"]))

Try this
