外掛說明

Control what menu items your site’s visitors see, based on visibility rules. Here are a few examples:

Display a menu item only if User is logged in
Hide menu items if Device is mobile
Display menu items for Admins and Editors
Hide Login or Register links for Logged in Users
Display menu items for Users from US or UK
Display menu items only for Customers with active membership
Display menu items for visitors browsing with Language English or Spanish

The plugin is easy to use, each menu item will have a new option “Change menu item visibility” which will enable the selection of visibility rules (example in Screenshots).

常見問題集

If Menu is broken, no visibility rules are available

There’s a known limitation with adding functionality for menu items in WordPress, and conflicts may happen between some plugins and themes.

If there are multiple plugins that extend Menu Items, for example If Menu and a plugin for Menu Icons, only one of them can add the needed functionality and the other one won’t work as expected.

This is an ongoing issue with WordPress which hopefully will be fixed in a future release.

If the “Menus” page is blank or options for visibility rules are not displaying, there is a way to test which plugin/theme causes this conflict.
Please disable other plugins or themes until you find the one that causes the problem, and contact the respective developers.
In the message include the link to WordPress ticket about menu items https://core.trac.wordpress.org/ticket/18584 where they can see detailed info on how to fix the problem.

Changes to menus are not saved

This problem may happen on sites with a large number of menu items.
In most cases, this is not a limitation or problem caused by plugins or WordPress, but by the hosting server.

Your hosting provider or server limits the amount of data that can be sent to WordPress for saving in database.
The setting is named “PHP max_input_vars” and it’s value should be increased, ex: max_input_vars = 200 to max_input_vars = 500.
Contact your hosting provider or make the change yourself if you have access. More details can be found here https://core.trac.wordpress.org/ticket/14134

How can I add a custom visibility rule for menu items?

New rules can be added by any other plugin or theme.

Example of adding a new custom rule for displaying/hiding a menu item when current page is a custom-post-type.

// theme's functions.php or plugin file
add_filter('if_menu_conditions', 'my_new_menu_conditions');

function my_new_menu_conditions($conditions) {
  $conditions[] = array(
    'id'        =>  'single-my-custom-post-type',                       // unique ID for the rule
    'name'      =>  __('Single my-custom-post-type', 'i18n-domain'),    // name of the rule
    'condition' =>  function($item) {                                   // callback - must return Boolean
      return is_singular('my-custom-post-type');
    }
  );

  return $conditions;
}

Where can I find conditional functions?

WordPress provides a lot of functions which can be used to create custom rules for almost any combination that a theme/plugin developer can think of.

Simple and easy to use.

Terrible coding, would NOT recommend

Stef 2021 年 1 月 14 日

Not going to do it. This thing needs a better design. You can't even read half the rules

godsdead 2021 年 1 月 13 日

The IP databases ARE FREE, this plugin is using free IP databases to do an IF statement an on Ip and CHARGE you a subscription. Scummy.

mateusvitor 2021 年 1 月 11 日

Does what it says, simple and straightforward. No complaints or problems from this plugin. It'd be cool if we could instead of hiding, making a menu item disabled. Or even better, allow it to have a tooltip or modal message.

Gotta love it when a plugin is super simple and easy to setup and use! This one definitely fits that bill.
