Include Exclude vs Show Hide vs Conditional Logic We have 3 extensions that can help you control the visibility of a meta box for a certain post/page: MB Include Exclude MB Show Hide MB Conditional Logic That might be confusing as you do not know which extension is the right choice for you. So the main difference between them is the following: MB Include Exclude hides meta boxes by PHP, meaning: Meta boxes are removed completely from the editing screen, no HTML markup is outputted at all Since meta boxes are removed completely, there are no inputs at all and thus, there are no meta values are saved at all There is no way to show the meta boxes again unless reloading the page Both MB Conditional Logic and Show Hide hide meta boxes by Javascript, meaning: The HTML of meta boxes are outputted, inputs are only hidden and the meta values are submitted when saving post and are saved in the database You can show them without reloading the page The MB Conditional Logic differs from Show Hide: it has more advanced options which allows you to show/hide not only meta boxes but also fields and specific HTML elements. The Show/Hide extension can show/hide only meta boxes. Besides, the number of conditions in Conditional Logic are more than Show/Hide extension (greater, less than, not equal, etc.).
