Hook to adjust country list?

[akust0m]

Hi there,

I'd like to only allow one country option instead of all of the country options available in 'includes/countries.php'.

I'd prefer a way to adjust this that will survive WHMCS updates. Is there a way to adjust the $countries array via a hook? Which hook point would I need to attach it to?

Thanks!

if you're using v7 or later then that file is no longer used...

the above method should do that.

I daresay you could if you had to, but the above method would be simpler.

Thanks @brian! 

Would be good if there was a way to specify the one country I want to allow instead disabling all-1. Oh well

instinctively, I think the safer method (e.g don't give WHMCS a reason to go wrong lol) would be to remove them as per above... but I can see that would be time-consuming, so if you really want to hardcode the countries array just to be one (or more) countries, then you could use the following hook...

<?php

/**
* Only Allow Specific Countries During Cart Ordering / Registration
* @author brian!
*/
 
function cart_only_allow_specific_countries($vars)
{
	$allowed = ['United Kingdom'];
	
	if ($vars['templatefile']=='viewcart'){
		$countries = $vars['countries'];
	}
	elseif ($vars['templatefile']=='clientregister'){
		$countries = $vars['clientcountries'];
	}
		foreach ($countries as $k => $country) {
			if (!in_array($country,$allowed)) {
				unset($countries[$k]);
			}
		} 
	if ($vars['templatefile']=='viewcart'){
		return array("countries" => $countries);
	}
	elseif ($vars['templatefile']=='clientregister'){
		return array("clientcountries" => $countries);
	}	
}
add_hook("ClientAreaPage", 1, "cart_only_allow_specific_countries");

so the above will code the checkout / registration pages to remove countries other than "United Kingdom"...

I suppose you could pull the allowed country from your localisation -> default country value instead of declaring it in the hook, but with no idea what you want to use this for, I just declared it as an array in the hook...

also, you might need to expand it for the clientregister page, but that is just a HTML string variable not an array (unlike the other two pages), so you could just code the string in the hook and return it... the complicating factor would be if the client current stored country value was different from the "allowed" country value and then that get more complicated - you could check in the hook for that (it's a basic if statement), but there's no point in coding that unless it becomes necessary.
