Re: Retrieving the multiple values set by a form

Hi Everyone,

I am passing a form to a php script for further processing.


I am able to retrieve the last value set for that given form variable
using
$variable=$_REQUEST['form_variable'];


My question is, what is the Php way of retrieving all the values passed
for the same form variable?

For example, if the php script is called with a syntax like


http://xxxx/get_variables.php?form_variable=value1&form_variable=value2&form
_variable=variable


, how do I iterate through all the values that form_variable has been
set to?

Thanks and regards,
Girish


if register_globals is ON then the variables are already set by php (which,
BTW, can cause all kinds of unexpected grief when html tag names end up as
php vars).

You can test the results by doing this:
<?php
if (!empty($_GET)) { # can't use !empty($_REQUEST) as it always has
something
echo "before foreach a=".$a.",b=".$b.",c=".$c."<br />"; // if
register_globals is on these are already set

# if register_globals is OFF this will set all request vars
foreach ($_REQUEST as $key => $value){
$$key = $value;
}
echo "after foreach a=".$a.",b=".$b.",c=".$c."<br />";
}
else {

echo <<<FORM
<form method="get" action="{$_SERVER['PHP_SELF']}">
<input type="text" name="a" />
<input type="text" name="b" />
<input type="text" name="c" />
<input type="submit" />
</form>
FORM;
}
?>


but be aware that $_REQUEST has extra stuff in it.
