Dreamweaver php form validation and redirect

Nov 28th, 2007

I post this solution to a form validation and redirect as an addition to a comment page written with dreamweaver. Unfortunately Dreamweaver does not provide server-side validation for php. You're expected to purchase an extension.
My problem
I have a comments page with a comment form. I wanted the comment input to a database if ok but if a user tried to input code or a link, I wanted to redirect them back to the form page without their comment input to the database. I also needed to work out where in the Dreamweaver written code to place my validation and redirect.

Here it is, I hope it helps somebody else.
 
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
 
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "comments"))
 {
 
 $comment = htmlentities($_POST['comment']);
 
function check_field1($comment)
{
if (preg_match("/&lt;/", $comment))
{
return TRUE;
}
}
$error=0; 
if(check_field1($comment))
{
 
  $error++;
   $insertGoTo = "comments.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $insertGoTo)); // $error=$error+1;
}
 
if($error == 0)
   $insertSQL = sprintf("INSERT INTO comments (comment, `day`, `month`, `year`) VALUES (%s, %s, %s, %s)",
                       GetSQLValueString($_POST['comment'], "text"),
                       GetSQLValueString($_POST['day'], "int"),
                       GetSQLValueString($_POST['month'], "text"),
                       GetSQLValueString($_POST['year'], "int"));
 
  mysql_select_db($database_connection, $connection);
  $Result1 = mysql_query($insertSQL, $connection) or die(mysql_error());
 
  $insertGoTo = "comments.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $insertGoTo));
  }

hi
Is this echoing out properly, or do you just need help with the javascript validation ?

Hi Designer,
I'm not actually asking for help here, I've posted this as a solution to the problem I posed here and in other posts. The above code works successfully. I could extend it with error messages and reproduction of the original comment to be edited but I decided to put a warning on the comments page not to post links or code, or the comment would be deleted.

Re javascript, I already have js client-side validation with error messages. Thank you anyway for your interest in this thread.

I am not sure if I am having a simoilar problem or it just sounds smilir to a new bie. I have acreated a form, www.lifespringnaz.com/form/lifegroup.html
I have redirected it to a "thank you " at www.lifespringnaz.com/form/confirm.html. Yet, I do not get the confirmation page and I can't figure it out. Also, In Explorer, when i hit th e the submit button I get a message "am I sure I want to send this from my email address"? and it changes the subject line. Is this something that can be eliminated? Thanks!

What is the problem actually ? Because the OP wasn't asking for any help !

I am not sure if you are replying to my post or another.
There are two problems:
Problem 1:
I have created a form, you can view it at: www.lifespringnaz.com/form/lifegroup.html
I want to redirected it to a "thank you " at www.lifespringnaz.com/form/confirm.html.
What code would I use here? And where do I put it?

Problem 2:
When filling out the form in Explorer, after I hit the the submit button I get a message "am I sure I want to send this from my email address"? ...it brings up the person’s email application and creates a message then you hit send. Is that going to work with everyone’s email apps? What if they just used web-based email?
I would like to eliminate those extra boxes, is there a way to have it generate that email il message internally without having the additional step of launching the email application.
Most forms I submit online like that don’t have the additional step/s after hitting submit. Lastly when the information is forwarded to me (the recipient), it seems to change the “subject” from Lifespring Report Form to “emailing . . “ So I want to eliminate the extra steps here and the changing of the subject line.

Thanks, Judi

By using a header function. Your page should be a php page and not html. I mean, www.lifespringnaz.com/form/lifegroup.html should be www.lifespringnaz.com/form/lifegroup.php to use the php functions. Or you can configure apache so that it parses html files using a php parser(which is lil complicated for time being). After doing whatever you wanna do with the posted form values, use this. header("location: www.lifespringnaz.com/form/confirm.html"); This will redirect the user to "Thank you" page.

This has something to do with the way you have written your script. You are probably having a javascript alert to confirm the sending of email. I don't know about person's email application. We need to look at the code to know what you are talking about.

You can use the mail function provided by php. AFAIK, php doesn't change any subject line! Again, you should show us your script to understand the problem.
