Unset Isset $_POST - is it possible?

[soma56]

Is it possible to unset a submit button?

 

<?PHP

if(isset($_POST['Submit'])) {

$date = $_POST['date'];

if ($date = '1966-10-03'){

     //Do Something

} else {

     //Possible to unset?
    unset($date);
    unset($_POST['Submit']); 

}


} else { ?>
<form action="" method="post">
<input type="text" name="date" />
<input type="Submit" name="Submit" value="Submit" />
</form>

<?PHP
}
?>

 

What I'm wondering is if it's possible to unset after submitting in the event of condition x. Should this not in turn echo out the form as it has been unset?

I bet it's possible

just do print_r ($_POST);  before and after and look at the output.

It will show the elements in the array $_POST

Just to show you can, test this script:

$_POST['monkeyballs']='lalala';
   print_r($_POST); // outputs:  Array ( [monkeyballs] => lalala )
   unset($_POST['monkeyballs']);
   print_r($_POST); //outputs: Array ( )

no. you check whether it is set when you enter the IF. unsetting it after you enter the IF doesn't make the IF false.

Try this

<?PHP
if(isset($_POST['Submit'])) {

$date = $_POST['date'];

if ($date = '1966-10-03'){

     //Do Something

$submitx=1;
} else {

     //Possible to unset?
    unset($date);
    unset($_POST['Submit']); 

}
}
if($submitx==0){
?>
<form action="" method="post">
<input type="text" name="date" />
<input type="Submit" name="Submit" value="Submit" />
</form>
<?PHP
}
?>

you probably want something more like

 

<?php

if(isset($_POST['date']) && $_POST['date'] == '1966-10-03') {
     //Do Something

} else {
?>
<form action="" method="post">
<input type="text" name="date" />
<input type="Submit" name="Submit" value="Submit" />
</form>

<?php
}
?>
