Question

Really simple I just think it’s me.

this is file 1.php

if(ctype_digit($_GET['id']))
{
    $item_id = "Hello";
}
else
{
    //Something
}

this is file 2.php

function item_show(){

        $item_query = "SELECT title FROM tbl_items WHERE id='" . mysql_real_escape_string($item_id) . "' ";

}

Now my question is how do I get the value of $item_id from 1.php inside the function in 2.php ?

To add file 1.php and file 2.php are both included in index.php

Answer 1

Is there anything stopping you just passing it as a function argument like this?

item_show($item_id);

or (the very hacky and not recommended):

function item_show(){
        global $item_id;
        $item_query = "SELECT title FROM tbl_items WHERE id='" . mysql_real_escape_string($item_id) . "' ";

}
