Laravel Nav Active state

Laravel Active is rewritten with a absolutely new API and  released with the new major version. This document explains the new API and gives some examples about its usage.

Installation

This version is compatible with the Laravel 5 only. Require it as one of your application dependencies via Composer:

composer require hieu-le/active

Add its service provider to your providers array in the config/app.php

HieuLe\Active\ActiveServiceProvider::class,

If you want to use an alias, register that alias inside the aliases array in the config/app.php

'Active' => HieuLe\Active\Facades\Active::class,

Get the active class based on a condition

Usage:

• Use the alias: Active::getClassIf($condition, $activeClass = 'active', $inactiveClass = '')
• Use the application container: app('active')->getClassIf($condition, $activeClass = 'active', $inactiveClass = '')
• Use the helper function: active_class($condition, $activeClass = 'active', $inactiveClass = '')

Explanation: if the $condition is true, the value of $activeClass is returned, otherwise the value of $inactiveClass is returned. The package comes with several methods to help you create conditions easier. You will get the class as a string as the result of these API.

active_class(true); // 'active'
active_class(false); // ''
active_class(if_uri([$currentUri]), 'selected'); // 'selected'
active_class(if_uri_pattern([$pattern1, $pattern2]), 'active', 'other'); // 'other'

Check the current URI

All of checking methods return boolean result (true or false). You can use the result in the condition of active_class or write your own expression.

Check the whole URI

Usage:

• Use the alias: Active::checkUri(array $uris)
• Use the application container: app('active')->checkUri(array $uris)
• Use the helper function: if_uri(array $uris)

Explanation: you give an array of URI, the package will return true if the current URI is in your array. Remember that an URI does not begin with the slash (/) except the root.

Check the URI with some patterns

Usage:

• Use the alias: Active::checkUriPattern(array $patterns)
• Use the application container: app('active')->checkUriPattern(array $patterns)
• Use the helper function: if_uri_pattern(array $patterns)

Explanation: you give an array of patterns, the package will return true if the current URI matches one of the given pattern. Asterisks may be used in the patterns to indicate wildcards.

Check the query string

Usage:

• Use the alias: Active::checkQuery($key, $value)
• Use the application container: app('active')->checkQuery($key, $value)
• Use the helper function: if_query($key, $value)

Explanation: the package will return true if one of the following condition is true:

• The current query string contains a parameter named $key with any value and the value of $value is false.
• The current query string does not contain a parameter named $key and the value of $value is null.
• The current query string contains a parameter named $key whose value is a string equals to $value.
• The current query string contains a parameter named $key whose value is an array that contain the $value.

// the current query string is ?x=1&y[0]=a&y[1]=b

if_query('x', null); // true
if_query('x', 1); // true
if_query('x', 2); // false
if_query('y', 'a'); // true
if_query('y', 'c'); // false
if_query('z', null); // false

Check the current route

Check the exact route name

Usage:

• Use the alias: Active::checkRoute(array $routes)
• Use the application container: app('active')->checkRoute(array $routes)
• Use the helper function: if_route(array $routes)

Explanation: you give an array of route names, the package will return true if the name of the current route (which can be null) is in your array.

Check the route name with some patterns

Usage:

• Use the alias: Active::checkRoutePattern(array $patterns)
• Use the application container: app('active')->checkRoutePattern(array $patterns)
• Use the helper function: if_route_pattern(array $patterns)

Explanation: you give an array of patterns, the package will return true if the name of the current route (which can be null) matches one of the given pattern. Asterisks may be used in the patterns to indicate wildcards.

Check the route parameter value

Usage:

• Use the alias: Active::checkRouteParam($key, $value)
