I'm newbie, I don't know anything about php, mysql; can you help me to write simple php script? I have a html page with forms: name*, email*, msg and a browser upload file. - I want when users submit this form, error will show if they don't enter require field * and check file size, type. - File upload (must be <500kb, allow only *.doc, *.txt, *.pdf type) - If all field ok, they will redir to confilm page. they click send and an email with these info with attach file (if they select) will be send to me@mydomain.com and redir they to thanks page. And users who enter these info will be record to contact system. (log name, email, ip, time gmt+7) Admin must login to view info about them and he can send email to users... Thanks for help. ---- Server IP: 66.163.161.117 Probable Submitter: 125.214.50.146 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.mail.php Edit -- http://master.php.net/note/edit/65553 Del: integrated -- http://master.php.net/note/delete/65553/integrated Del: useless -- http://master.php.net/note/delete/65553/useless Del: bad code -- http://master.php.net/note/delete/65553/bad+code Del: spam -- http://master.php.net/note/delete/65553/spam Del: non-english -- http://master.php.net/note/delete/65553/non-english Del: in docs -- http://master.php.net/note/delete/65553/in+docs Del: other reasons-- http://master.php.net/note/delete/65553 Reject -- http://master.php.net/note/reject/65553 Search -- http://master.php.net/manage/user-notes.php
