I have problem with the ajax file. The ajax file does not work with the php form. when I run the code it displays an error file_get_content error, file name empty.
The php code is working properly. but the ajax file cannot transfer the file field value. So the file cannot attach with mail.
it shows the error: file name empty
plz help me to pass the file field value through the ajax file.
