$_POST vs. 'post'

[shahpound]

Hi,

In a component I created, depending on the system, visitors will get errors from this:

$this->assignRef( 'name', JRequest::getVar( 'name','', 'post', 'string') );

but not from this:

$this->assignRef( 'name', JRequest::getVar( 'name','', $_POST, 'string') );

The error is from PHP:

*Fatal error*: Only variables can be passed by reference in ... [filename]

Any ideas why this happens and what the difference is?

Instead of including the getVar method within the assignRef method, set the variable first and then pass the variable to assignRef(). Such as

Code: Select all

$name = JRequest::getVar( 'name','', 'post', 'string');
$this->assignRef('name', $name);

Thanks for the reply, is there really a difference (other than syntatically of course) betweenthese two methods?

I believe yours is passing the value of the string, the other is passing a reference to the value.

The correct way to do what you are wanting to do is:

Code: Select all

$this->assign( 'name', JRequest::getVar( 'name','', 'post', 'string') );

You cannot assign a value by reference... you may only assign a reference by reference.

JView::assignRef() assigns by reference.
JRequest::getVar() returns a value.

Thanks Louis. Always helps to get it 'from the source'.
