I'm creating a plugin that is using the
add_menu_page function to create a page for my plugin options. This means that the url for my plugins main options page is like this
Now, in my plugin options page there is a standard form with a drop down menu that lets people choose what data they want to display.
<form> <select name="data-to-get"> <option value="1">Foo</option> <option value="2">Bar</option> </select> <input type="submit" value="get-data"> </form>
Currently, when you select an option and click the button you are taken to this url:
This ends up loading a new page which is just blank. What I want to happen is this:
I know that WordPress has a built in function
add_query_arg so I need to do something like this:
add_query_arg( 'data-to-get', '1', 'http://localhost:8888/LFB/wp-admin/admin.php?page=lfb-player-stats' );
However, where I'm stuck is that I don't know how to hook this in. It needs to be inserted after the select value has been chosen and when the get request from the form is sent.
