Posted: Wed Oct 14, 2015 7:23 pm Post subject: MIME header generator function. |
|
|
The plugin will generate a(n almost) correct "Name: value" MIME headers for things like EML or MHT files. Basically any MIME-appropriate container.
It has some shortcuts, and if someone fancy, I would gladly accept the patches to fill in the blanks.
Example usage:
Code: | $smarty->assign('header', array(
'from' => array('name' => 'Me', 'email' => 'me@example.com'),
'to' => array('name' => 'You', 'email' => 'you@example.com'),
'subject' => 'Last sunday of october.'
));
{foreach $header as $name => $value}{mime_header name=$name value=$value}
{/foreach} |
Parameters:
name(string) - header name
value(string or array*) - header value
wrap(number, optional) - wrap length (default is an iconv comple-time default)
*If 'name' refers to one of the known address headers (To, From, Sender, Cc etc.), 'value' can be an array of 'name'-'email' pairs as well, indicating recipient names and addresses, which it will try to correctly stitch together into appropriate address string.
The plugin (iconv is required, mbstring [should be] optional):
Code: | <?php
/** Smarty function plugin
*/
function smarty_function_mime_header($params, Smarty_Internal_Template $template)
{
$_name = mb_convert_case($params['name'], MB_CASE_TITLE);
$_value = $params['value'];
$_pref = array(
'input-charset' => is_callable('mb_internal_encoding')
? mb_internal_encoding()
: 'UTF-8',
'output-charset' => is_callable('mb_internal_encoding')
? mb_internal_encoding()
: 'UTF-8'
);
isset($params['wrap']) ? $_pref['line-length'] = $params['wrap'] : false ;
switch($_name)
{
case 'From':
case 'Sender':
case 'To':
case 'Cc':
case 'Bcc':
case 'Resent-From':
case 'Resent-Sender':
case 'Resent-To':
case 'Resent-Cc':
case 'Resent-Bcc':
if(!is_array($_value))
{
throw new Exception('Compound address strings support not implemented yet.');
}
if(!isset($_value['email']))
{
throw new Exception('Address not defined or multi-recipient header is requested (not yet implemented).');
}
$_aname = isset($_value['name']) ? mb_encode_mimeheader($_value['name']) . ' ' : '';
if(is_array($_value['email']))
{
$_address = '';
foreach($_value['email'] as $v)
$_address .= (empty($_address) ? '' : ', ') . "<$v>";
$_address = mb_encode_mimeheader($_address);
}
else
{
$_address = "<{$_value['email']}>";
}
return "$_name: {$_aname}{$_address}";
default:
return iconv_mime_encode($_name, $params['value'], $_pref);
}
} |
