Trimming $HTTP_POST_VARS

[Anon]

I'me writing some code to process an HTML form. The first thing I'd like to do is to trim whitespace from all items in $HTTP_POST_VARS. Previously I was doing this variable by variable, ie:

$name = trim($name);
$address = trim($address);

but that's getting rather long winded as I add more and more fields.

Does anyone have any code that just loops through all variables in $HTTP_POST_VARS and trims them and puts them back?

Hi Murray,

Try this:

reset( $HTTP_POST_VARS );
while(list($k,$v)=each($HTTP_POST_VARS)){
$$k = trim($v);
}

This will set them to global and trimmed.

reset( $HTTP_POST_VARS );
while(list($k,$v)=each($HTTP_POST_VARS)){
$HTTP_POST_VARS[$k] = trim($v);
}

This will leave them in the HTTP_POST_VARS array but they will be trimmed - this will not change the global vars.

Bye,

Matt

Excellent! Thanks, Matt, that was exactly what I was looking for.
