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

Hi Girish,

In the example you have given, which equates to a Get, the variables will
indeed overwrite each other with only the last value surviving, as stated by
lorento.

You can however create an array by suffixing the variable name (in the HTML
form) this
<input name='inp[0]' type='hidden' value='first value'>
<input name='inp[1]' type='hidden' value='second value'>
<input name='inp[2]' type='hidden' value='third value'>

once this is received by your PHP script the values may be retrieved :

$myArray = $_REQUEST('ip'); // note no subscripts required

$myArray['0'] will contain 'first value', $myArray['1'] the second value,
and so on

BTW Register globals should be OFF on any production machine so there is
little point in having it on in a development machine.
