在WordPress中添加文本和变量wp_nav_menu $ menu_class

Question

I am generating a menu in WordPress using wp_nav_menu() function and I want to add both text and variable into the 'menu_class' property.

Now this is how I do it:

 `'menu_class'      => 'text' . $variable,`

However no class is shown when I use this method (no error/warnings as well).

I want to know how to add the text "text" and the variable "$variable" into 'menu_class' property?

Thanks

Answer 1

here's the documentation for wp_nav_menu() . It says for menu_class...

the class that is applied to the ul element which encloses the menu items. Multiple classes can be separated with spaces. Formerly known as $wrap_class

so try adding a space?

'menu_class'      => 'text' . ' ' . $variable,

or just

'menu_class'      => 'text ' . $variable,

this is apparenlty a good tutorial: IMPROVE YOUR WORDPRESS NAVIGATION MENU OUTPUT

This SO post deals with code that deals with two menu classes: php code optimization for wordpress nav menu . Are you sure that your variable has a value? I work with PHP all the time and that's definitely how you do string concatenation.
