Forms within functions

Anon

Can anyone tell me how to get a form to work within a function. If I use the code below outside of a function everything works just fine. However if I attempt to modularize the code and put it within a function, which I need to do, it doesn't work? Ideas.....?

<?PHP

store();

//******** FUNCTIONS

function store()

{

echo("<form enctype=\"multipart/form-data\" action='$PHP_SELF' method=\"post\">");

for($i=1;$i<=4;$i++)

{

    echo("<br><input type=radio name='item' value='This is item number $i'>Item #$i");

}

echo("<br><br><input type=submit name=submit value='Make your selection'>");

if(($HTTP_POST_VARS[ "submit"]))

{

    echo("$item");

}

echo("</form>");

}

Searching helps, so does reading manuals.

Functions have their own variable-scope.
That means, any variables declared outside the function is not accessible inside the function.

Either pass the $HTTP_POST_VARS etc through the function parameters, or import them using the global() function.

You can also, insted of using the global() function, insert this line at the start of the function:

global $HTTP_POST_VARS;

Then it should work

That is what I meant... it's not really a function, but all it's missing are the parentheses..

I tried doing a search and looking in the manual before posting and I did not find anything helpfull. I tried passing the $HTTP_POST_VARS through the function and as a global and it doesn't work. I have even tried passing $PHP_SELF along with $HTTP_POST_VARS. Is there anything else I am missing?

                Thanks

<?PHP

store($HTTP_POST_VARS, $PHP_SELF);

//******** FUNCTIONS

function store($HTTP_POST_VARS, $PHP_SELF)

{

echo("<form enctype=\"multipart/form-data\" action='$PHP_SELF' method=\"post\">");

for($i=1;$i<=4;$i++)

{

    echo("<br><input type=radio name='item' value='This is item number $i'>Item #$i");

}

echo("<br><br><input type=submit name=submit value='Make your selection'>");

if(($HTTP_POST_VARS[ "submit"]))

{

    echo("$item");

}

echo("</form>");

}

try adding $item to the list of paramaters being passed.
