Remove Onclick from Donwload link(href),

and call that function in to php function function File_Downloads($file, $name, $mime_type='') { //Your send mail function echo '<script> function sendMail(str) { //your content } </script>'; } function File_Downloads($file, $name, $mime_type='') { //Your send mail function echo '<script> function sendMail(str) { //your content } </script>'; }
