How to fetch the GET/POST elements in a form without knowing the name of the controls inside the form

Question

I had the list of items. When the user clicks a item, a div is generated with a textbox <input type="text" name="(DYNAMICALLY ASSIGNED VALUE)" />

So user can select multiple items. For each item a textbox is generated dynamically inside the form. When the user clicks the submit button, i want to fetch the GET/POSTED elements. How can we achieve that?. plz help. Any help will be appreciated.

Answer 1

You can use a for-each loop:

foreach ($_GET as $get_key => $get_value)

Answer 2

You could use a foreach loop on $_POST like Matthew suggested or you could set the names of the inputs as an array

for example

<input type="text" name="foo[]">

foreach ($_POST['foo'] as $key => $value) {
    ...
}

The data would look like something like this

[foo] => Array
     (
         [0] => ...
         [1] => ...
         [2] => ...
         [3] => ...
     )
