The below snippet is provided as-is as an example, but support for custom code is not something we can provide.
You are running the Client Portal, but want to find a way to modify the Dashboard message, perhaps give it a bit of personalisation like Hi, Mike welcome to your dashboard.
The below plugin example will do that via the dashboard content filter.
<?php
/*
Plugin Name: Jetpack CRM Portal Filter Plugin
Plugin URI: https://jetpackcrm.com
Description: Jetpack CRM is the simplest CRM for WordPress. Customise the Dashboard welcome message with this plugin.
Version: 1.0
Author: Jetpack CRM
Author URI: https://jetpackcrm.com
Text Domain: zero-bs-crm
*/
add_filter('zbs_portal_dashboard_content', 'zeroBS_custom_portal_dashboard_filter');
function zeroBS_custom_portal_dashboard_filter($dashboard){
$uid = get_current_user_id();
$uinfo = get_userdata( $uid );
$cID = zeroBS_getCustomerIDWithEmail($uinfo->user_email);
if($cID > 0){
//again if we have a contact returned, get the meta
$customer_meta = zeroBS_getCustomerMeta($cID);
$dashboard = "<p>";
$dashboard .= "Hello " . $customer_meta['fname'] . ", welcome to your Dashboard";
$dashboard .= "</p>";
return $dashboard;
}
return $dashboard;
}
?>
The above will check whether the core is active, and then only modify the dashboard if we have a contact ID linked to the logged in WP user.
