Rather complicated PHP project for novice

Sep 7th, 2008

I am building a confidentiality form which I would like to submit to a printable page and to two or three email addresses (one being the email address of the person who filled the form out). This means that the language that is above the form needs to be printed out as well. I would also like to put the names into a database so that each time the person logs in that they are not greeted by this form.

Can someone help me or at least direct me to what I should be looking for?

Thanks in advance!

Great,

Create a database table for users with a field for if they've gone through the confidentiality page.
http://dev.mysql.com/doc/

Use sessions and or cookies so logged in users can skip the page.

And use PHP mail function to send your email.

If you have specific questions I will try and help with them.

Cheers

Hi Langsor,

Thanks so much for helping me. I took a look at this link and it is great information. But I guess my main question is that I would like to know if I can send an email to the address that is filled out in the form. I have been searching and searching for info on this for a few days now, but so far I have gotten no where. I understand that there is a way to authenticate an e-mail address that is filled into a form, but I still have not found any code which puts the e-mail address into my code so that I can send that person a copy of the form.

Is there a way I can do that? Or do I have to figure out a different way to get the form to the client?

Hi,

Getting the email address to the mail function is pretty easy if the user enters their email with the form information.

main_form.html

<form action="form_script.php" method="POST">
  <label>Name: <input type="text" name="name" /></label>
  <label>Email: <input type="text" name="email" /></label>
  <label>... some other form values ...</label>
  <input type="submit" value="Submit This Form" />
</form>
<form action="form_script.php" method="POST">
  <label>Name: <input type="text" name="name" /></label>
  <label>Email: <input type="text" name="email" /></label>
  <label>... some other form values ...</label>
  <input type="submit" value="Submit This Form" />

    This is my summary of the form with submitted values from the form embedded into it.

ENDFORM;
 
$recipient1 = "$name <$email>" // client copy
$recipient2 = "Admin <admin@my_domain.com>";

$headers .= "Reply-To: $recipient2"."\r\n";
$headers .= "X-Mailer: PHP-Mailer";
 
mail( "$recipient1,$recipient2,$recipient3", $subject, $form, $headers );

$recipient1 = "$name <$email>" // client copy
$recipient2 = "Admin <admin@my_domain.com>";
$recipient3 = "Me <me@my_domain.com>";

$subject = "The cool form you just filled out";

$headers = "To: $recipient1"."\r\n"; // send Addressed-To copy to client
$headers .= "From: $recipient2"."\r\n";
//$headers .= "Cc: Carbon-Copy <copied@some_site.com>"."\r\n";
$headers .= "Bcc: $recipient2, $recipient3"."\r\n"; // send Hidden copy to self and ???
$headers .= "Reply-To: $recipient2"."\r\n";
$headers .= "X-Mailer: PHP-Mailer";

mail( "$recipient1,$recipient2,$recipient3", $subject, $form, $headers );

?>

In the above example I did NOT test it and I suspect there are some errors in the way I set up the Bcc and mail( "$recipient1,$recipient2,$recipient3", ... lines, since I don't know if putting all addresses in the mail( "..." portion will hide the addresses in the Bcc portion ??? So you will want to test all this thoroughly.

Otherwise, I hope this gives you an idea of one way you might handle the form and email for your project -- there are, of course, always more than one way to skin a goose ;-)

Cheers

Hi Langsor,

Your example has worked wonderfully. Now, would you be able to help me make a few fields required? I have tried several different ways, all with varying issues in them that did not make them work the right way.
Thanks very much!

Glad it worked.

The fun thing about making fields required is that you probably want to check them on the client (web browser) before submitting the form -- it's easier for the visitor to change fields before it's submitted -- and this requires JavaScript; but you also want to check them on the server (PHP side) since you can't rely on JavaScript since it can be disabled or circumvented too easily. But then again, most people don't do this.

In JavaScript you walk through the form fields and test the ones that are required. If they don't pass the test, you alert the visitor in some manner.

In PHP you do the same thing, and then re-publish the form with the failed fields highlighted in some manner, while keeping the other fields filled in from the first submission.

There are, of course, multiple ways to accomplish all of the above tasks. Here is one simplified way you might do this with both JavaScript and PHP ... it could be built up to be more comprehensive and use better checking tests, but as an example ...

 php Syntax (Toggle Plain Text) 
<?php
if ( $_REQUEST['submit'] ) { // don't test just on page load, form was submitted
  $required = array( 'name','email' ); // required fields array
  $errors = array(); // error output array
  foreach ( $required as $field ) { // test for all required fields
    if ( !$_REQUEST[$field] ) { // if not found
      // I'm skipping the lame email test here ... it's not worth not doing it right and I don't have time
      $errors[] = strtoupper( $field ); // push to output
    }
  }
  if ( count( $errors ) ) { // if errors ...
    $warning = '<br /><strong>There was an error with the form submission.</strong><br />Please complete these fields: ';
    $warning .= implode( ', ', $errors );
  }
}

Due to the line-wraps it's difficult to understand this example ... I would copy the plain-text (Toggle Plain Text link above) and paste the above code into a code-editor with line numbers and syntax highlighting ...

Hope it helps :-)
