manipulating $_POST??

[mosizlak]

Hi all -
I'm having fits trying to manipulate the values passed from an html form via "post". I thought I'd be able to do something like this:

$myvar = $_POST[0];
print $myvar;

or like this:

$myvar = $_POST[0][0];
print $myvar;

or like this:

$myvar = $_POST[$fldname];
print $myvar;

But these aren't working. What does work is this:

$myvar = $_POST['fieldname'];
print $myvar;

. . . but this doesn't help me since the receiving script will have different fieldnames every time a form is submitted.

So my questions are:

1) can php evaluate $_POST's values by index number or by inserting a variable?

2) if not then how do you access $_POST's values?

If anyone knows of a good resource out there (i.e. online tutorials) would you let me know?

Thanks in advance.

$myvar = $_POST[$fldname];
print $myvar;

will work, but $fldname has to be defined, like
$fldname = 'FirstName';

You can't use integer indeces for the $_POST, because everything is stored associatively. You could use a foreach loop to iterate through each field, regardless of the name.

thanks Diego! you're good people.

I finally got the $_POST[$fldname] syntax to work with your help.

Now I won't be fired!
