POST variables

[jjjamie]

Is there an easier way to get post data into ordinary variables (or an array) without having to write something like...

if (isset($POST['accountnum']))
accountnum = $POST['accountnum'];
else
accountnum = "";

(or)

isset($POST['accountnum']) ? accountnum = $POST['accountnum'] : accountnum = "";

Just in case anyone mentions it, I don't want to use the 'register globals' directive because of the security element. I need a way to easily dump the post vars into normal vars or if that's not possible, dump them into an array.

Thanks for any help in advance :-)

extract ($_POST);

*there is no point in dumping $_POST into an array, it is already and array.

[crusty_php]

if (!empty($GET)) {
extract($GET);
} else if (!empty($HTTP_GET_VARS)) {
extract($HTTP_GET_VARS);
}

if (!empty($POST)) {
extract($POST);
} else if (!empty($HTTP_POST_VARS)) {
extract($HTTP_POST_VARS);
}

That's from PHPMyAdmin (to give proper credit)

afaik, register globals must be off for extract() to even have any signifigance, ie:

extract($GET);
extract($POST);

if ($button)
{
//
}

page.php?button=1 is still going to trigger, regardless if it's your 'form' value

I would recommend just doing this:

extract($GET);
extract($POST);

if ($_POST['button'])
{
// It's safe to use $name now
}

Or even foreach()'n, but, I guess it's up to you.

register_globals essentially runs the extract function accross EGPCS arrays. Bear in mind that empty form text inputs will register as empty varibles but unchecked checkboxes and radio buttons will not register at all, so you cannot simply do:
if ($checkbox) { // do something}
you must do:
if (isset ($checkbox)) { // do something}

*result vary depending on your error reporting settings

It's okay because all my field are text fields 🙂 Thanks for all your help. I believe you have all answered my question really well 🙂
