hook for admin addonmodule

[jimlongo]

I'm trying to write a hook that will either display a success message or a form depending on some php logic.

So far I have a hook, that in real simple terms is like this

add_hook('AdminAreaPage', 1, function ($vars){
	$extraVariables = [];
	$are_we_connected = true;  // sparing you our custom code, but this could be false
	if ($are_we_connected) {
		$extraVariables['isConnected'] = true;
	}else{
		$extraVariables['isConnected'] = false;
	}
    return $extraVariables;
});

Then in the template file I have 

{if $isConnected}
show the success message
{else}
show the form
{/if}

Seems to me this should display the success message, but it continues to show the form.

 

If I do something like this the page displays the correct message,

{if 1==1}
show the success message
{else}
the form
{/if}

so I'm assuming i'm not using the $extraVariables[] properly.

 

Any hints would be appreciated, TIA.
