andrew_biggart Posted October 5, 2010 Share Posted October 5, 2010 I am trying to add some simple validation to my form. I only wanter users to be able to enter 11 numbers into the number field or else it will say 11 digit numbers only. A validation to only allow users to input numbers anything else and it brings up an error. and finally i want to check the email string to make sure it has an @ and a (.) . How would i go about adding these validation techniques to this code? <?php if ($_SERVER['REQUEST_METHOD']=="POST"){ // Recipent Email $to="[email protected]"; $subject="Reply to Peppermint Invitation"; $title = $_POST['title']; $name = stripslashes($_POST['name']); $add1 = stripslashes($_POST['add1']); $add2 = stripslashes($_POST['add2']); $add3 = stripslashes($_POST['add3']); $add4 = stripslashes($_POST['add4']); $postcode = stripslashes($_POST['postcode']); $number = stripslashes($_POST['number']); $email = stripslashes($_POST['email']); $time = $_POST['time']; $from = ($_POST['name']) . "<".stripslashes($_POST['email']).">"; $subject = ($_POST['name']) . "<".stripslashes($_POST['email']).">"; // Email Message $message = "Name : $title $name. Address : $add1, $add2, $add3, $add4, $postcode. Phone Number : $number. Email : $email. Appointment Time : $time"; // Validation Begins // Add Erros To Array $errors = array(); // Check Form if (!$_POST['title']) $errors[] = "Title Required"; if (!$_POST['name']) $errors[] = "Name Required"; if (!$_POST['add1']) $errors[] = "Address Required"; if (!$_POST['add4']) $errors[] = "City Required"; if (!$_POST['postcode']) $errors[] = "Postcode Required"; if (!$_POST['number']) $errors[] = "Number Required"; if(!$_POST['number'] == 11) $errors[] = "Full Number Required"; if (!$_POST['email']) $errors[] = "Email Required"; if (!$_POST['time']) $errors[] = "Time Required"; // Display Errors if (count($errors)>0) { echo"<h1 class='fail'>"; foreach($errors as $err) echo "$err.\n"; echo"</h1>"; echo " <form method='post' action='#'> <table cellpadding='0' cellspacing='0' border='0'> <tr> <td class='form_results' colspan='2'> </td> </tr> <tr> <td class='form_left' valign='top'> <table width='200' border='0' cellspacing='0' cellpadding='0'> <tr> <td class='title_left' valign='top'>Title</td> </tr> <tr> <td class='sname_left' valign='top'>Name</td> </tr> <tr> <td class='add_left' valign='top'>Address</td> </tr> <tr> <td class='post_left' valign='top'>Postcode</td> </tr> <tr> <td class='number_left' valign='top'>Phone Number</td> </tr> <tr> <td class='email_left' valign='top'>Email Address</td> </tr> <tr> <td class='time_left' valign='top'>Appointment Time</td> </tr> </table> </td> <td class='form_right' valign='top'> <table width='300' border='0' cellspacing='0' cellpadding='0'> <tr> <td class='right_spacer'> <select name='title' class='select'> <option>Mr</option> <option>Mrs</option> <option>Ms</option> <option>Miss</option> </select> </td> </tr> <tr> <td class='right_spacer'><input type='text' name='name' class='field' value='$name' /></td> </tr> <tr> <td class='right_spacer'><input type='text' name='add1' class='field' value='$add1' /></td> </tr> <tr> <td class='right_spacer'><input type='text' name='add2' class='field' value='$add2' /></td> </tr> <tr> <td class='right_spacer'><input type='text' name='add3' class='field' value='$add3' /></td> </tr> <tr> <td class='right_spacer'><input type='text' name='add4' class='field' value='$add4' /></td> </tr> <tr> <td class='right_spacer'><input type='text' name='postcode' class='field' value='$postcode' /></td> </tr> <tr> <td class='right_spacer'><input type='text' name='number' class='field' value='$number' /></td> </tr> <tr> <td class='right_spacer'><input type='text' name='email' class='field' value='$email' /></td> </tr> <tr> <td class='right_spacer'> <select name='time' class='select'> <option>5.30 pm</option> <option>6.30 pm</option> <option>7.30 pm</option> </select> </td> </tr> </table> </td> </tr> <tr> <td class='form_buttom' colspan='2'> <input name='submit' type='submit' value='Submit' class='submit_button' /> </td> </tr> </table> </form> "; } else { // Build message headers $headers = "From: $from\r\n" .

BlueSkyIS Posted October 5, 2010 Share Posted October 5, 2010 this function will return a string stripped of all but numbers. then you can count the numbers: function allNumbers($input_str) { // FASTER?return preg_replace("/[\D]/","",$input_str);} for finding a specific character in a string, check out stristr(), or preg_match() for more power Link to comment https://forums.phpfreaks.com/topic/215212-simple-form-validation/#findComment-1119296 Share on other sites More sharing options...
