Make Custom template

You can make custom template and load it from anywhere (Theme, Plugin). First look at our default simple template.

It's located at \pdf-invoices-and-packing-slips\templates\simple.

Simple template code

Under simple folder, you'll see two folders (invoice & packing). It's fine to make template for only invoice OR packing-slips.

Example folder structure for invoice template:

\custom-template-name\invoice

Inside invoice folder, You must have one required file called template.php

Then you need to register custom template :

// For "invoice"
add_filter('pips_packing_templates', 'register_invoice_templates');

function register_invoice_templates($invoice_templates) {
   $invoice_templates['custom-template-name'] = __('Custom Template', 'text-domain');

   return $invoice_templates;
}


// For "packing-slips"
add_filter('pips_packing_templates', 'register_packing_templates');

function register_packing_templates($packing_templates) {
   $packing_templates['custom-template-name'] = __('Custom Template', 'text-domain');

   return $packing_templates;
}

Locate your custom template :


// For "invoice"
add_filter('pips_invoice_template_locate', 'update_invoice_template_path', 10, 2);

function update_invoice_template_path($path, $invoice_template) {
   if ($invoice_template === "custom-template-name") {
      return dirname(__FILE__) . '/templates/' . $invoice_template . '/invoice';
   }

   return $path;
}


// For "Packing-slips"
add_filter('pips_packing_template_locate', 'update_packing_template_path', 10, 2);

function update_packing_template_path($path, $packing_template) {
   if ($packing_template === "custom-template-name") {
      return dirname(__FILE__) . '/templates/' . $packing_template . '/packing';
   }

   return $path;
}

Now go on Template settings, You'll seen custom template as option.
