to do with users in this case
function userEdit( $row, $option, $submitvalue, &$params )
I've never come across this syntax for an argument, how is it used? what will it change?
also what does this do
require_once ( $mainframe->getPath( 'front_html' ) );
thanks

In your first question, are you asking how to pass an argument to a function? Or something else?
As for the second question.
require_once ( $mainframe->getPath( 'front_html' ) );
Is saying that this file, is trying to include another file, which is the nave of the component.html.php. front_html is basically an internal variable constant referring to the components .html.php file, which is used normally to do the actual html presentation.

That helps me a lot as I couldnt see any includes for the components constructed with html.php files and .php files, that must be the line.
For the first part the bit I dont get is the "&" just before the argument$params, does this concatenate the current $params with new $params ?
thanks

A '&' in php is actually used to pass a variable as a reference, so &$params means pass the memory location of $params, instead of making a copy of $params for that function. It is intended to cut down on unnecessary memory usage, and to make your program faster. However, it is optional. It would be ok to pass $params as the argument, however, if you do any changes to the $params variable inside your function, you will have to return $params upon completion, and update it outside of the function. So, in most cases, it is easier and faster to pass it as a reference using the & operator. Of course, there are instances when this is not ideal, and it is better to pass a copy of %params instead of having the function use a global $params.
Hope that helps.

Im getting the following error when trying to use the above instead of just including (in this case) "display.html.php";
Code: Select all
Fatal error: Call to a member function getPath() on a non-object in C:\Uniform3_1_1s\www\landedAt\components\com_journal\journal.php on line 113
the object doesnt exist, ive tried the line global $mainframe which doesnt work.
thanks for any help

Your component is named com_journal so the display.html.php has to renamed to journal.html.php

But it is a separate template from journal.html.php. I want to have many templates for this component. Does this mean that I just should use
require(display.html.php);
is there anything wrong with that cause this works.
thanks

Ian (or anyone else),
Is there a fairly straight forward way, or some class already defined in Joomla that I can use to dump my $_POST vars into an array and use sessions to pass them along in the component?
that way I don't have to rely passing everything along via the URL?

The getPath directly by using with front_html, class etc is limit to only this files, for other you need to use require.
