Display Hook Function on viewinvoice.tpl

[Waranugraha]

Hello,

I have create hook on quotepdf.tpl

this is the code :

 

function landingflash_invoice_hook($vars) {

return array(
'pagetitle' => $vars['pagetitle'] . '<br><div style="font-size:12px;">'
landingflash_generate_code( $vars['invoiceid']).'</div>',
);
}
add_hook(ClientAreaPageViewInvoice", 1, "landinfglash_invoice_hook");

function landingflash_generate_code($invoice){

$secret_key = 'lfgapura';
$secret_iv = '123456';

$encrypt_method = 'AES-256-CBC';
$key = hash('sha256', '$secret_key');
$iv = substr( hash('sha256' , $secret_iv), 8, 16);

return base64_encode( openssl_encrypt($invoice, $encrypt_method, $key, 0, $iv));
}

And then i want to display it under invoice ID on viewInvoice.tpl  and it should displayed like this : http://prntscr.com/138455n

Do you know how to display the function result?

Thank you

you have three issues...

1. you mention quotepdf.tpl, but I assume you're really talking about invoicepdf.tpl, e.g invoices and not quotes.
2. you cannot use hooks with either of the pdf templates - you would need to edit the relevant template directly.
3. if you wanted the hook to work on the HTML invoice, then the following should work...

   <?php
   
   add_hook('ClientAreaPageViewInvoice', 1, function($vars) {
   	
   	$secret_key = 'lfgapura';
   	$secret_iv = '123456';
   	$encrypt_method = 'AES-256-CBC';
   	$key = hash('sha256', $secret_key);
   	$iv = substr( hash('sha256' , $secret_iv), 8, 16);
   	$hash = base64_encode(openssl_encrypt($invoice, $encrypt_method, $key, 0, $iv));
   	$pagetitle = $vars['pagetitle'] . '<br><div style="font-size:12px;">'. $hash . '</div>';
   	return array("pagetitle" => $pagetitle);
   });

   ... but to repeat, no hook would work on the PDF invoices, but you can use PHP when editing those templates.
