[RESOLVED] loop through $_Post variables?

[npd1164]

Assuming one did NOT know what form fields (either qty or their names) were going to be passed, is it possible to somehow loop through them?

for (i = 0; i<= count($_POST);i++) {
//do something;
}

or

foreach ($_POST) {
//do something;
}

I know neither of the above is correct - but is there a proper syntax to achieve something like this?

You could use a foreach ($_POST as $key => $value), I believe.

[npd1164]

$y = 0;
foreach ($_POST as $key => $value){
echo $key. ": " .$value . "<br>";
$y++;
}
echo "Total Fields Posted: " . $y. "<br>";

No problem. For future reference, you may want to use the boards [ php ] tags around your code for better readability. Also, don't forget to mark this resolved. 😉
