    Php Sessions

    D3158 replied to D3158's topic in PHP Coding Help

    Thanks. WIll try it. Also, I don't need to call $_SESSIONS in my submitted-contact.php to make it work also? :\ EDIT: Even though I added session_start(), to my submitted-contact.php file at the very top, it doesn't work. I know it's a lot of code but I'd really appreciate it if you (Langstra) can read the entire thing and provide me with pointers and/or solution on why it doesn't work. It's so bothering me. :|

    Basically I've a Contact Form where a user fills in Name, Email Address and Comments and then there is aSubmit button. If I just hit "Submit" without filling in anything or wrong information, it takes me to this page,send_form_email.php. This page has all the validators in it. I want it to sort of (I say sort of because I still need to check whether they input everything correctly) bypass this page and go to "submitted-contact.php" page (it's going to this page but its not showing the following as specified in the 2) where it displays one of the 2 things: 1) Login Success 2) Try Again! Right now, there's nothing showing. :| send_form_email.php has this at the very top and it calls header location to the page, submitted-contact.php SEND_FORM_EMAIL CODE [/b] [b]<?php session_start(); $_SESSION['error']=true; $_SESSION['error']=false; ?> <?php if(isset($_POST['email'])) { // EDIT THE 2 LINES BELOW AS REQUIRED $email_to = "blah@hotmail.com"; $email_subject = "Your email subject line here"; function died($error) { // your error code can go here echo $error; die(); } // validation expected data exists if(!isset($_POST['first_name']) || !isset($_POST['email']) || !isset($_POST['comments'])) { died(''); } $first_name = $_POST['first_name']; // required $email_from = $_POST['email']; // required $comments = $_POST['comments']; // required $error_message = ""; $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/'; if(!preg_match($email_exp,$email_from)) { $error_message .= 'The Email Address you entered does not appear to be valid.<br />'; } $string_exp = "/^[A-Za-z .'-]+$/"; if(!preg_match($string_exp,$first_name)) { $error_message .= 'The First Name you entered does not appear to be valid.<br />'; } if(strlen($comments) < 2) { $error_message .= 'The Comments you entered do not appear to be valid.<br />'; } if(strlen($error_message) > 0) { died($error_message); } $email_message = "Form details below.\n\n"; function clean_string($string) { $bad = array("content-type","bcc:","to:","cc:","href"); return str_replace($bad,"",$string); } $email_message .= "First Name: ".clean_string($first_name)."\n"; $email_message .= "Email: ".clean_string($email_from)."\n"; $email_message .= "Comments: ".clean_string($comments)."\n"; // create email headers $headers = 'From: '.$email_from."\r\n". 'Reply-To: '.$email_from."\r\n" . 'X-Mailer: PHP/' . phpversion(); $sendit= @mail($email_to, $email_subject, $email_message, $headers); if($sendit){ header('Location:submitted-contact.php'); }else{echo "Email failed to send";} } ?> SUBMITTED-CONTACT.PHP CODE <!DOCTYPE html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"><style type="text/css"></style> <title>CKK Internet Marketing</title> <link href="style.css" rel="stylesheet" type="text/css" media="all"> <link rel="stylesheet" type="text/css" href="http://fonts.googleapis.com/css?family=Lato"> <link rel="shortcut icon" href="images/favicon.ico" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <script src="js/jquery.sticky.js"></script> <script src="js/jquery.cycle.all.js"></script> <script src="js/jquery.smoothscroll.js"></script> <script> $(document).ready(function(){ $(".navigation").sticky({topSpacing:0}); }); </script> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-27381915-2']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

I have been trying to figure this out for the past couple of days! :| Thanks guys D3158

Select your option: Radio button: Add Radio button: Modify Radio button: Delete Line No. to Delete/Modify = dropdown (doesnt have any values to it... I am assuming it's because the content within the table isn't shown which is indicated by line number 1 to 10 or something.. BUT it has this mean thing: <br> <b>Notice</b>: Undefined variable: arrayContent in <b>/home/..../..../..../public_html/..../Lab6/classes.php</b> on line <b>89</b><br/>) Content to Add/Modify = Hrs [Dropdown from 1:00-24:00] Mins[Dropdown from 1:00-59:00] Day [Dropdown from 1-31] Month[Dropdown from 1-12] Year [Whatever year user wants to input] E-mail[Whatever email user wants to input] Message[Whatever message user wants to input] SUBMIT RESET Thanks!
