herghost Posted August 2, 2008 Share Posted August 2, 2008 How do I validate certain boxes in a form? Is it possible without java? I have to pages, the 1st being the HTML for the form: <form method="POST" action="mailer.php"> <p> </p> <table width="66%" border="0" align="center"> <tr> <td width="31%">Name:</td> <td width="23%"> </td> <td width="46%"><input type="text" name="name" size="19"></td> </tr> <tr> <td>Email Address:</td> <td> </td> <td><input type="text" name="email" size="19"></td> </tr> <tr> <td>Your Message </td> <td> </td> <td><textarea rows="9" name="message" cols="30"></textarea></td> </tr> <tr> <td>Join Mailing List?</td> <td> </td> <td><input type="checkbox" name="check[]" value="join_yes">Yes</td> </tr><tr> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><div align="center"> <input name="submit" type="image" value="Submit" src="images/send.jpg"> </div></td> <td><div align="center"> <input class="reset_button" type="reset" value="" /> </div></td> <td> </td> </tr> </table> <p><br> <br> </p> <p><br> <br> <br> <br> </p> </form></p> </form> and the second is the send function php file: <?php if(isset($_POST['submit'])) { $to = "[email protected]"; $subject = "Contact Form"; $name_field = $_POST['name']; $email_field = $_POST['email']; $message = $_POST['message']; foreach($_POST['check'] as $value) { $check_msg .= "Checked: $value\n"; } $body = "From: $name_field\n E-Mail: $email_field\n Message:\n $message\n $check_msg"; echo "Thankyou for your message, you will now be returned "; mail($to, $subject, $body); } else { echo "blarg!"; } ?> How would I validate that all boxes have been filled (apart from the checkbox) and the email address is in the correct format?

PHPTOM Posted August 3, 2008 Share Posted August 3, 2008 You didn't say if you were using PHP 5 or not. But this is a PHP file email validator in it. <?php if(isset($_POST['submit'])) { $to = "[email protected]"; $subject = "Contact Form"; $name_field = $_POST['name']; $email_field = $_POST['email']; $message = $_POST['message']; if(!$name_field || !$email_field || !$message){ echo "You missed a field!"; }elseif(!filter_var($email_field, FILTER_VALIDATE_EMAIL)) { echo "Invalid email!"; }else{ foreach($_POST['check'] as $value) { $check_msg .= "Checked: $value\n"; } $body = "From: $name_field\n E-Mail: $email_field\n Message:\n $message\n $check_msg"; mail($to, $subject, $body); echo "Thankyou for your message, you will now be returned "; } }else{ echo "You didn't press the submit button"; } ?> Link to comment https://forums.phpfreaks.com/topic/117839-solved-simple-form-validation/#findComment-606579 Share on other sites More sharing options...
