Creating Form Session Variables

M_RT

I am trying to create a routine where the $_Post values from my form are posted into a list of session variables.

I am aware that this can be done manually by doing the following:

session_start(); 

$_SESSION['value'] = $_POST['value'];
$_SESSION['value2'] = $_POST['value2'];
$_SESSION['value3'] = $_POST['value3'];

But as my form has a varying number of fields that change depending on previous selections made, I need to create a loop that will automatically generate and register my $_Post values in the session?

Can anyone help with this?

You might do the following...

Presumption: your fields are named something like name1, name2, name3 etc.

You could do is form a loop like this:

$i=0;
$max_number = 10;//maximum fields that can be passed through a form
while($i<$max_number){
     $i++;
     $fn = "name".$i;
     if(isset($_POST[$fn])){//if post exists create a sesion variable
          $_SESSION[$fn] = $_POST[$fn];
     }
}

Try this

session_start(); // Start sessions
$i = 1; $max = 10; // Set min and max number of values
while ($i < $max) {
$_SESSION['value'.$i] = $_POST['value'.$i];
$i++;
}

Unfortunately it's not as easy as that..... :bemused:

I am creating the form field from database reference that can't be changed!!

I have been playing with this routine that displays all of the form names and values:

foreach ($_POST as $key=>$val) { 
echo $key . ' = ' . $val . '<br />';   

}

I wonder if this can be addapted??

foreach($_POST as $key => $val)
{
	$_SESSION[$key] = $val;
}
