Hello,
thanks for response, i actually solve my problem by using Wire Mail SMTP Module.
http://modules.processwire.com/modules/wire-mail-smtp/
its same like wireMail() and also have attachment option too, vary easy to use.
Thanks
Thanks every one for helping me. here is what i did to solve my issue just to help some one if he looking for same solution.
my website directory structure is
Home
⌊ site1
⌊ site
⌊ wire
⌊ site2
⌊ site
⌊ site3
⌊ site
if you see i have only one directory of wire in site1 folder. in other two websites site2 and site3 i created a PHP file in root and name it link.php
so i can access this site like http://domain/link.php or http://localhost/site2/link.php
here is my code for link.php
<?php// for localhost , we can also set this according to our web server path also
$target = '/Applications/XAMPP/xamppfiles/htdocs/site1/wire';
$shortcut = 'wire';
symlink($target, $shortcut);
echo readlink($shortcut);
?>
when you run this PHP this will create a link directory to your WIRE directory and website will start working
