I have a function that works perfectly (from within a script). But when I
make it a class (object) and call it from an external file, I get the
following error:
Warning: Missing argument 1 for display_records() in
http://www.friendshipcenter.com/Objects/display_records.inc on line 5
Warning: Missing argument 2 for display_records() in
http://www.friendshipcenter.com/Objects/display_records.inc on line 5
After the warnings, it executes the function without passing values to the
variables (i.e., it doesn't work), and then it executes the function a
second time perfectly (with the appropriate variables).
Line 5 is this:
function display_records($row, $record_count)
It displays the first error message for $row, and the second error message
for $record_count.
I call the function with this:
$my_records = new Display_Records;
$my_records -> display_records($row, $record_count);
The full scripts are below.
What I tried that didn't help was declaring the variables in the class with:
class Display_Records {
var $row;
var $record_count;
I also tried setting defaults for the variables (er, attributes) with this
(it didn't help):
$my_records = new Display_Records;
$my_records -> row = $row;
$my_records -> record_count = 1;
$my_records -> display_records($my_records -> row, $my_records ->
record_count);
This is my first try at OOP. The code is for a personal ad website
(FriendshipCenter.com). Here's the full class script, followed by the
script I use to call the function.
