If Menu – Visibility control for Menus Plugin

One of the most popular uses of the plugin is to show the “Register/Login” menu for non-logged-in users, and “Your account” for logged-in users.

To enable this for “Register/Login” menu, follow these steps:
1. Go to WordPress Admin on your website -> Appearance -> Menus
2. Expand the menu item for “Register” or “Login” page
3. Enable the option “Enable visibility rules”
4. Choose the rule “Hide if user logged in”

For showing the “Your account page”, follow these steps:
1. Go to WordPress Admin on your website -> Appearance -> Menus
2. Expand the menu item for “Your account page” page
3. Enable the option “Enable visibility rules”
4. Choose the rule “Show if user logged in”

Multiple visibility rules can be used at once, like so:

For showing a menu item only for admins on desktop:
1. Go to WordPress Admin on your website -> Appearance -> Menus
2. Expand the menu item you want
3. Enable the option “Enable visibility rules”
4. Choose the rule “Show if user is Administrator”
5. Click the “+” button at the end of the visibility rule, and change to “AND”
6. On the newly added row, choose “Hide if device is mobile”

For showing a menu item for Admins or users with an active subscription:
1. Go to WordPress Admin on your website -> Appearance -> Menus
2. Expand the menu item you want
3. Enable the option “Enable visibility rules”
4. Choose the rule “Show if user is Administrator”
5. Click the “+” button at the end of the visibility rule, and change to “OR”
6. On the newly added row, choose “Show if Has active subscription __”

To remove an extra visibility rule:
1. Go to WordPress Admin on your website -> Appearance -> Menus
2. Expand the menu item with multiple visibility rules
3. Click on the “AND” / “OR” buttons at end of visibility option
4. Change to “+”

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.

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

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; } 

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.
