PHP post method passing

[dagoat10]

I am trying to pass a variable to a php form but it is not passing through. The lines are the following:

echo "<form action='create_table_test2.php', method='post'>";
while($NumCols > 0)
{
    echo "<input type='text' name='Col$ColNum' />
    $ColNum++;
    $NumCols--;
    echo "<br>";
}
echo $NumCols2;
echo "<input type='hidden' name='Cols' value=$NumCols2 />";
echo "<br>";
echo "<input type='submit' name='Change' value='Change Table' />";
echo "</form>";

then i am trying to retrive it like this:

print $_POST["$Col$ColNum"];

or this

print $_POST['Col$ColNum'];

is it not possible to do this?

Neither one of those would work directly. The first one would need the value of the $Col variable to be the 'Col' string. So it matches the name of your fields.

And the second one simply doesn't expand the variables when between single quotes. Perhaps what you want to do is:

$_POST[[red]"[/red][blue]Col[/blue][green]$ColNum[/green][red]"[/red]]

Alternatively:

$_POST[[red]"[/red][blue]Col[/blue][red]"[/red] . [green]$ColNum[/green]]

Provided $ColNum is set to a number that exists in your input loop.
