Retrieve form data for class object

[Techron]

Too simple? I hate to ask. I need to retrieve form data from an html form for a class / class object. What is easiest method to do this??

Variables posted via a form will be found either within the $_POST or $_GET arrays depending on your forms method.

You can just return them like normal, can't you?

 

try this:

 

test-class.php:

<?php

class Test
{
function printVars() {
	foreach ($_GET as $key => $val) {
		print 'GET: [' . $key . '] ' . $val . '<br />';
	}
	foreach ($_POST as $key => $val) {
		print 'POST: [' . $key . '] ' . $val . '<br />';
	}
}
}

?>

 

 

test.php?some=vars&to=print:

<?php

include 'test-class.php';

$test = new Test();
$test->printVars();

?>

That code will produce errors. If there are no post values and only url params you will get a foreach error on the foreach($_POST) as not array will exist. Same other way around.

 

As Thorpe said if your form uses a POST method the values will be contained in the $_POST array and in the $_GET array if using the GET method.

To display the array after form submission use print_r();

 

// display submitted input
// using POST method
print_r($_POST);

 

You can then access the data as you would a normal array.

ahh okay, testing at work with errors disabled, didn't think about that. Well to be hoenst wasn't really supposed to be anything more than a simple demonstration that you can still access $_GET and $_POST in the same way..
