致命错误：无法在Wordpress网站的写入上下文中使用函数返回值

Question

  

致命错误：在第61行的/public_html/wp-content/plugins/radiantthemes-addons/custom-menu/class-radiantthemes-style-menu.php的写上下文中不能使用函数返回值

'description' => empty( rt_get_menu() ) ? esc_html__( 'Custom menus not found. Please visit <b>Appearance > Menus</b> page to create new menu.', 'radiantthemes-addons' ) : esc_html__( 'Select menu to display.', 'radiantthemes-addons' ),

Answer 1

这可以通过在变量中采用这样的值来解决

$description = empty( rt_get_menu() ) ? esc_html__( 'Custom menus not found. Please visit <b>Appearance > Menus</b> page to create new menu.', 'radiantthemes-addons' ) : esc_html__( 'Select menu to display.', 'radiantthemes-addons' );

并像这样使用它

'description' => $description,

Answer 2

首先，您必须将rt_get_menu()函数返回值存储在类似$rt_get_menu = rt_get_menu();的变量中 只需将您的行代码替换为-

'description' => empty( $rt_get_menu ) ? esc_html__( 'Custom menus not found. Please visit <b>Appearance > Menus</b> page to create new menu.', 'radiantthemes-addons' ) : esc_html__( 'Select menu to display.', 'radiantthemes-addons' ),
