Question

<?php

$sessionTotal = 10;

        for($initial = 1; $initial <= $sessionTotal ; $initial++){
            echo '<input type="text" name="menuItems" size="20" /><br /><br/>';
        }

    //I have a if statement here checking if the submit button isset, yada yada, after I press the submit button, it returns this error -> Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\yada\yada-yada.php on line 43

    foreach($_POST['menuItems'] as $value)
    {
    echo $value;
    }

?>

It will echo $value after it is submitted. I have a if statement checking if the submit button isset, yada yada, after I press the submit button, it returns this error -> Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\yada\yada-yada.php on line 43

Answer 1

$_POST['menuItems'] is not an array, foreach only accepts arrays and certain objects.

If you make it

<?php

$sessionTotal = 10;

        for($initial = 1; $initial <= $sessionTotal ; $initial++){
            echo '<input type="text" name="menuItems[]" size="20" /><br /><br/>';
        }

    //I have a if statement here checking if the submit button isset, yada yada, after I press the submit button, it returns this error -> Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\yada\yada-yada.php on line 43

    if ( is_array( $_POST['menuItems'] ) ) 
    foreach($_POST['menuItems'] as $value)
    {
    echo $value;
    }

?>

It should work.
