Basic:

What's inside

Problem:

Marking an active item is a common essential part in any UI, providing a visual indication of the state of an item. This is commonly used in PHP like:, _(*5)

$current_page = 'contact'; 

<li class="<?= $current_page == 'home' ? 'active' : '' ?>"><a href="#home">Home</a></li>
<li class="<?= $current_page == 'about' ? 'active' : '' ?>"><a href="#about">About</a></li>
<li class="<?= $current_page == 'contact' ? 'active' : '' ?>"><a href="#contact">Contact</a></li>

Repeating this code in different parts of your application where you need to mark the active state, will make the code harder to read, harder to maintain., _(*6)

Some solutions out there have the downsides: 1- Framework-Specific Package. 2- Completely based on the URL Route. 3- Only one item can be marked as active., _(*7)

Solution:

The package will load the methods set_active, get_active and is_active, set_active will set a given settings to a static variable inside the Mohannadnaj\Active class, this settings answer the questions: what is the active item? what should it return if the check is passed? or should it return boolean? and what is the key you want to attach all this settings to?, _(*8)

The above example can be translated to:      , _(*9)

set_active('navbar', 'about');

<li class="<?= is_active('navbar', 'home'); ?>"><a href="#home">Home</a></li>
<li class="<?= is_active('navbar', 'about'); ?>"><a href="#about">About</a></li>
<li class="<?= is_active('navbar', 'contact'); ?>"><a href="#contact">Contact</a></li>

the set_active method will consider the first argument set_active('navbar' , ...) as a setter for the active element we want to catch later, that is 'about'., _(*10)

Requirements:

• PHP >=5.3

Development:

• Check out the tests/ActiveStateTest.php Test Case to see different examples of using the helper methods., _(*11)

• Consider keeping it compatible with older PHP versions (>=5.3), personally, I used PHPCompatibility to do the checks for me., _(*12)

• TODO: Better documentation. Better consistant syntax (accept and return types) for using the methods., _(*13)
