Solusvm instructions in welcome emails and line breaks

[dimitrifrom31]

Hi,

 

With whmcs v5/6 I was using {$service_custom_field_instructions|nl2br} to include linebreaks for the solusvm custom field "instructions" as else it was writing everything on the same line.

Now with v7 the welcome email is not sending with the following error:

 

Smarty Error: Syntax error in template "mailMessage:mailMessage:plaintext" on line 26 "{$service_custom_field_instructions|nl2br}" modifier 'nl2br' not allowed by security setting

 

How can this be worked around as without linebreaks the instructions are quite not readable.

 

Thank you

Hello dimitrifrom31,

 

Thank you for your post on the community forums.

 

WHMCS 7.0 introduces support for Smarty Security Policies. The default policies are to allow all PHP functionality in system templates but only a restricted predefined list of functions and modifiers in email templates.

 

The nl2br function should be on the acceptable list however you may need to modify your own policy please refer to this support note for more assistance on updating your policy.

I had no custom list set so I have no idea why I cannot use it. I tried to make a policy as follows but I still got the error:

// Smarty custom email based template policy:
$smarty_security_policy = array(
   'mail' => array(
       'php_functions' => array(
           'nl2br',
       ),
   ),

Hi,

The code to add your your configuration.php file would be:

 

// Smarty custom email based template policy:
$smarty_security_policy = array(
   'mail' => array(
       'php_functions' => array(
           'nl2br',
       ),
   ),
);

);

 

That's what I just tried again but it does not work:

Email message rendered empty - please check the email message Smarty markup syntax
