I am working with the "secure" version of contact form script 12.1 described in "Chapter 12 - Security Methods" (pg. 365) but would like to modify this so that rather than simply printing a thank you message, the user is redirected to a thank you page. I have tried replacing the given script: // Minimal form validation: if (!empty($scrubbed['email'])) { // Create the body: $body = "Name: {$scrubbed['name']}\n\nComments: {$scrubbed['comments']}"; $body = wordwrap($body, 70); // Send the email: mail('XXX@XXX', 'Contact Form Submission', $body, "From: {$scrubbed['email']}"); // Print a message: echo '<p><em>Thank you for contacting me. I will reply some day.</em></p>'; // Clear $_POST (so that the form's not sticky): $_POST = array(); } else { echo '<p style="font-weight: bold; color: #C00">Please enter a valid email address.</p>'; } with modified: // Minimal form validation: if (!empty($scrubbed['email'])) { // Create the body: $body = "Name: {$scrubbed['name']}\n\nComments: {$scrubbed['comments']}"; $body = wordwrap($body, 70); // Send the email: mail('XXX@XXX', 'Contact Form Submission', $body, "From: {$scrubbed['email']}"); // Redirect to thank you page: header("Location: thankyou.htm"); exit(); // Clear $_POST (so that the form's not sticky): $_POST = array(); } else { echo '<p style="font-weight: bold; color: #C00">Please enter a valid email address.</p>'; } ..but get the error: Warning: Cannot modify header information - headers already sent by (output started at /websites..... Reading about this, it seems nothing can be sent to the browser before header is used. But however I try to move things around, I cannot get this to work. Could you advise how/where this redirect should be used within this script? Thank you.

Hi. I'm using xampp 1.8.0 with Windows 7 SP1, 32 bit OS, and coding HTML5 and CSS3. I'm just learning PHP, and I created a contact form for a dentist's Website, so that patients can request appointments. An email should go to the dentist and display the information that the user entered. (I only coded the 'name' and 'description' to be in the email so far, since this is just a test.) I'm using Javascript to check if the patient filled out the form properly, so I didn't use some of the code shown on pg. 332 of the book. There is an error on the first line: Parse error: syntax error, unexpected 'POST' (T_STRING), expecting ']'. Can someone tell me what's wrong? Thanks. <?php if ($_SERVER['REQUEST_METHOD] == 'POST' { body = "Name: ($POST['name']}\n\nComments: {$_POST['description']}"; $body = wordwrap($body, 70); mail('mail@yahoo.com', 'Contact Form Submission', $body, "From: {$_POST['email']}"); echo 'Thank you for your request. A member of our staff will be contacting you shortly.'; $_POST = array(); } ?> <div id="form"> <div id="contain"> <form action="EmailConf.php" method="post"> <table class="form_demo"> <tr> <td> <label>Name</label> </td> <td> <input class="input_full" type="text" id="name" name="name" required="required" /> </td> </tr> <tr> <td><label for="email"> Email </label> </td> <td> <input class="input_full" type="email" id="email" name="email" required="required" /> </td> </tr> <tr> <td> <label for="tel"> Phone </label> </td> <td> <input class="input_full" type="tel" id="tel" name="tel" required="required" /> </td> </tr> <tr> <td><label for="priority_normal"> Priority </label> </td> <td> <input type="radio" name="priority" id="priority_urgent" value="Urgent"> <label for="priority_urgent"> Urgent </label> <input type="radio" name="priority" id="priority_normal" value="Normal" checked="checked"> <label for="priority_normal"> Normal </label> </td> </tr> <tr> <td> <label for="date">Enter a date:</label> </td> <td> <input class="input_xlarge" type="text" id="date" name="date" required="required" /> <script> (function($){ var pickerOpts = { minDate: new Date(), maxDate: "+3m,", showButtonPanel: true, showOn: "button", buttonImage: "images/cal.png", }; $("#date").datepicker(pickerOpts); })(jQuery); </script> </td></tr> <tr><td>Enter a time: </td> <td><input id="time1" name="s2Time1" /> <script type="text/javascript"> $('#time1').ptTimeSelect({ popupImage: 'Select Time' }); </script> </td> </tr> <tr> <td> <label for="description"> Reason for<br /> appointment </label> </td> <td> <textarea id="description" name="description" rows="3" required="required"></textarea> </td> </tr> </table> <hr /> <p class="clearfix"> <input type="submit" value="Submit" class="float_left" /> <input type="reset" value="Reset" class="float_right"> </p> </form>
