EnglishConditional displays in WHMCS allow you to show or hide content based on certain conditions being met. This is particularly useful for customizing the user experience based on specific criteria. Here's how you can implement conditional displays:
1. Using IF Statements in Smarty Templates:
WHMCS uses the Smarty template engine, which supports conditional statements. You can use {if}, {else}, and {/if} to conditionally display content.
For example, you might use this to show different content to clients based on their membership level:
{if $clients_group eq 'Platinum'}
Welcome Platinum Member!
{else}
Welcome Standard Member!
{/if}
2. Using Conditional Statements in PHP Hooks:
You can create custom PHP hooks in WHMCS to add conditional logic. This requires some programming knowledge.
add_hook('ClientAreaHomepage', 1, function($vars) {
if ($vars['clientsdetails']['groupid'] == 1) {
return array("content" => "<p>Welcome Standard Member!</p>");
} else {
return array("content" => "<p>Welcome Platinum Member!</p>");
}
});
3. Using WHMCS's Built-in Conditional Functions:
WHMCS provides several built-in functions to perform conditional checks:
is_null($variable): Checks if a variable is null.is_array($variable): Checks if a variable is an array.is_string($variable): Checks if a variable is a string.is_numeric($variable): Checks if a variable is numeric.is_int($variable): Checks if a variable is an integer.
4. Conditional Display in Custom Addons or Modules:
If you're creating a custom addon or module, you can implement conditional logic within your PHP code. This allows you to control what content or functionality is displayed based on specific conditions.
5. Conditional Display in Templates:
You can also use conditional logic in your custom template files to control the display of elements based on certain conditions.
Remember to always test your conditional displays thoroughly to ensure they work as expected. Improperly implemented conditional logic can lead to unexpected behavior or errors.
