Global varible problem, please help

[Anon]

Hello I wonder if I could seek some advice/help.

I\'m trying to build a function to create the sql query for a form which was built from components I have allow the user to input into a the database.

Once they have clicked on the submit button all the form object then go as varibles to the next page, this is correct and normal, but for my query making function I need to define global varibles for my function, but I just have a list of the varibles which are stored in an array, and I need to define these so I can access the information in the function.

$iq = explode(\"@\", $iq_array); so now the varibles are in $iq[0], $iq[1] but global $iq[1]; doesn\'t do what I want, since this doesn\'t define $version_checked(which is stored in $iq[1]) as a global varible.

Many thanks,

Benny

so you have a method=post form producing post variables, which are to be processed in a function, and you're struggling with getting those variables set global?

at the beginning of the function, do:

global $HTTP_POST_VARS;

then you can access then in the function via $HTTP_POST_VARS['inputname'] or (maybe more interesting given that you don't know their names) loop through them using foreach or list() etc.

I hope I got your point ...

Hi,

it would actually help to see what exactly you are doing, but this is what you generally do to access global arrays:

function myUsefulFunction()
{
global $myArray;

for ($i=0;$i<count($myArray);$i++)
{
echo $myArray[$i];
}
}

Hope this helps,
