Prev: A stupid question about classes
Next: How do I use date_diff in my code (both codes are included, mine and the example function) I need process.php
From: Nick Balestra on 2 May 2010 10:41 I am trying to understand how the joomla framework works, i see an heavy usage of " :: " in its code, here an example: function edit () { JRequest::setVar('view, 'single'); $this ->display(); } from my really basic php understanding in the function edit i call a function setVar() and i pass the paramter 'view' and 'single' in it then the output ($this) is passed to the display() function. My question is what does :: means? an more precisely referring to the example: JRequest::setVar('view, 'single'); how do you read it and how do you manage it? Cheers, Nick
From: Nick Balestra on 2 May 2010 10:48 I think si related to class and methods, JRequest Class have a method called setVar, right? if this is correct sorry for posting the question, i just haven't started yet classes and methods...;-) On May 2, 2010, at 4:41 PM, Nick Balestra wrote: > I am trying to understand how the joomla framework works, i see an heavy usage of " :: " in its code, here an example: > > function edit () > { > JRequest::setVar('view, 'single'); > $this ->display(); > } > > > from my really basic php understanding in the function edit i call a function setVar() and i pass the paramter 'view' and 'single' in it then the output ($this) is passed to the display() function. > > My question is what does :: means? an more precisely referring to the example: JRequest::setVar('view, 'single'); how do you read it and how do you manage it? > > Cheers, Nick
