Conditional Items Based on Permissions

v1.1+

The add method and all convenience methods (link, html, action,...) have an equivalent method with an IfCan suffix. When used, the item will only be added if the currently logged in user has a certain permission.

Menu::new()
    ->link('/', 'Home')
    ->linkIfCan('view-posts', '/posts', 'Posts');
<!-- User isn't logged in or can't view posts -->
<ul>
    <li><a href="/">Home</a></li>
</ul>
<!-- User is logged in and can view posts -->
<ul>
    <li><a href="/">Home</a></li>
    <li><a href="/posts">Posts</a></li>
</ul>

If your permission check requires parameters, you can provide an array for the permission. The permission's name should be the first element, and parameters should fill up the rest.

Menu::new()
    ->link('PostController@show', 'View post')
    ->linkIfCan(['edit-post', $post], 'PostController@edit', 'Edit post');
<!-- User isn't logged in or can't edit the post -->
<ul>
    <li><a href="/posts/1">View post</a></li>
</ul>
<!-- User is logged in and can edit the post -->
<ul>
    <li><a href="/posts/1">View post</a></li>
    <li><a href="/posts/1/edit">Edit post</a></li>
</ul>
