You can do more with the mail functionfor example, you can set additional email headers to cc ("carbon copy") or bcc ("blind carbon copy," where the recipient doesn't know a copy was also sent to someone else) people. To set such headers, you use the additional_headers parameter in the call to the mail function: mail(string to, string subject, string message [, string additional_headers [, string additional_parameters]]) Note that you use \r\n to separate headers (although some Unix mail transfer agents may work with just a single newline, \n). Example 9-9, phpemailheaders.html, lets the user set "cc" and "bcc" addresses. Example 9-9. Using headers, phpemailheaders.html<HTML> <HEAD><TITLE>Send me some email with headers</TITLE></HEAD> <BODY><CENTER> <H1>Send me some email with headers</H1> <BR> <FORM METHOD=POST ACTION="phpemailheaders.php"> Please enter your message and click Submit: <BR> cc: <INPUT TYPE="TEXT" NAME="cc"> bcc: <INPUT TYPE="TEXT" NAME="bcc"> <BR> <TEXTAREA NAME="message" COLS="50" ROWS="5"></TEXTAREA> <BR> <INPUT TYPE="SUBMIT" VALUE="Submit"> </FORM> </CENTER></BODY> </HTML> You can see what this page looks like in Figure 9-9. Figure 9-9. Sending email with headers.In phpemailheaders.php, Example 9-10, we check the cc and bcc data, and if either exists, we add them to the variable $headers: if(isset($_REQUEST["cc"])){ $headers .= "cc:" . $_REQUEST["cc"] . "\r\n"; } if(isset($_REQUEST["bcc"])){ $headers .= "bcc:" . $_REQUEST["bcc"] . "\r\n"; } After we've set the headers as needed, we use the mail function to send the email, as you see in phpemailheaders.php, Example 9-10. Example 9-10. Sending email with headers, phpemailheaders.php<HTML> <HEAD><TITLE>Sending email</TITLE></HEAD> <BODY> <CENTER> <H1>Sending email</H1> Your email was sent. <BR> <?php $headers = ""; if(isset($_REQUEST["cc"])){ $headers .= "cc:" . $_REQUEST["cc"] . "\r\n"; } if(isset($_REQUEST["bcc"])){ $headers .= "bcc:" . $_REQUEST["bcc"] . "\r\n"; } $result = mail("steve@chooseanisp.com", "Web mail", $_REQUEST["message"], $headers); ?> </CENTER> <BODY> </HTML> This script sends the email to steve@chooseanisp.com, along with the cc and bcc addresses. |
