Utils/TabbedBrowser is a module that provides tabbed interface four our module. 'Tabbed' like in modern internet browsers.


To create instance of the module, like for every module in epesi, we type:

$tabbed_browser = & $this->init_module('Utils/TabbedBrowser');

To display its content:



Inline tabs

Method syntax
$tabbed_browser = & $this->init_module('Utils/TabbedBrowser');
$tabbed_browser->start_tab( <tab name> );
	[tab's content]
$tabbed_browser = & $this->init_module('Utils/TabbedBrowser');
$tabbed_browser->start_tab( 'Tab One' );
	print 'Some data for tab one.';
$tabbed_browser->start_tab( 'Tab Two' );
	print 'Some data for tab two.';
$tabbed_browser->start_tab( 'Tab Three' );
	$i = 12;
	print 'And a variable for tab three: ' . $i;

This code displays three tabs. Their content is determined by what you place between start_tab and end_tab methods.

Callback tabs

Method syntax
$tabbed_browser = & $this->init_module('Utils/TabbedBrowser');
$tabbed_browser->set_tab( <tab name>, <callback function> );
$tabbed_browser = & $this->init_module('Utils/TabbedBrowser');
$tabbed_browser->set_tab( 'Tab One', array($this, 'function_1') );
$tabbed_browser->set_tab( 'Tab Two', array($this, 'function_2') );
$tabbed_browser->set_tab( 'Tab Three', array($this, 'function_3') );
  • First parameter is name for a tab.
  • Second parameter tells, what function should be called, when tab is activated. Structure of second parameter may by a little confusing, so let's detail its structure.
    • First element is class, where the called method is located. In this case, it's the same module, where $tabbed_browser is located.
    • Second element is name of the method to be called. The method has to be present in module named by first element and has to have public access -- otherwise it will not be shown.

The above code will create two tabs ('Tab One' will be show by default). Content of this tab is whatever function function_1 prints. Respectively, 'Tab Two' and 'Tab Three', when activated, display what function_2 and function_3 print.

More functionality

Utils/TabbedBrowser ofer a few methods to simplify its usage. Those include:

  • set_default_tab(<tab number>) -- lets you specify, which tab should be displayd by default.
  • switch_tab(<tab number>) -- switches dislayd tabs from within php file.
Note: When you use this method, remember to add [tabbed browser instance]->tag() method in each tab.
