Hey people

I'm totally new to ajax/xajax, and not all that hot on php either... sorry 'bout that  Embarrassed

I've had a long hard look at the tutorial to make the safe contact form (http://www.finalwebsites.com/tutorials/php_ajax_contact_form.php Visit through proxy), but I can't work out where I need put all the different bits of code. The tute suggests to put the form and function 'before all the html code' - but if I put it in my page, anyone viewing the source will be able to see the passwords for the mail server.

Could someone please give me a clue here?

Many thanks

Hi,

are your sure that php is working well?

only output is parsed by the browser, can you post some code?

Shortly after posting I realised I had to save my file as contact.php, not contact.html (duh), which has solved the issue of people viewing the source.
However, there seems to be an issue with the following code:


$form = '<form id="cform">
            <div>
              <label for="name">Name</label>
              <input name="name" type="text" id="naam" value="" size="25" />
            </div>
            <div>
              <label for="email">E-mail</label>
              <input name="email" type="text" id="email" value="" size="25" />
            </div>
            <div>
              <label for="msg">Message</label>
              <textarea name="msg" id="msg" cols="45" rows="5"></textarea>
            </div>
            <div style="border-top:1px solid #CCCCCC;padding-top:5px;">
              <label for="subbtn" style="text-align:right;"> --&gt; </label>
              <input type="button" id="subbtn" value="Submit" onclick="xajax_myFunction(xajax.getFormValues('cform'));" />
            </div>
          </form>';


When I run the page through a browser, it doesn't like the following line:


<input type="button" id="subbtn" value="Submit" onclick="xajax_myFunction(xajax.getFormValues('cform'));" />


At this point the browser tells me it happened across an unexpected T_STRING. I changed ('cform') to ("cform") which fixed that error, but now the form doesn't do anything...

you need to escape the single quotes (not replacing them with double quotes)

Thanks very much, that's fixed it.. until it hits the next bug that is!

Now I get a popup message telling me that the XML Response received from the server is invalid - and it goes on to display the entire contents of my <html></html> tags.

Problem is that I can't see the entire message, because it's too long - it goes past the bottom of my screen and I can't move it up enough to see the end!

The email gets sent, but the form doesn't disappear.

I'm trying to fiddle with it a bit to see if I can hooky it back together, I think it's something to do with the following code:

$objResponse->addAssign('contact_result', 'innerHTML', $data);
return $objResponse;

Do I need to define 'innerHTML' somewhere?

use the debug option from Xajax:

$xajax->bDebug = true;

OK, I set debug=true, and the debug told me that the response was too long.
So I seriously trimmed the HTML code to try and make it short enough to appear on the browser message, and it had advised me that it 'cannot modify header information'
Headers already sent by my .php page, but a new header is requested by xajax.inc.php
I'm guessing I can modify this somewhere?

one more question. I change this first peace of script from php to perl, i mean i just change <?php to <script type=.... etc. you see, in this tutorial at
http://www.finalwebsites.com/tutorials/php_ajax_contact_form.php Visit through proxy
they dont explain which code is for js and which for php, so i just trying different ways. So, when i change to javascript, at least my page start work a bit.

Now i have next trouble. I've got fatal error with this line:
<?php $xajax->printJavascript('xajax/'); ?>
i read article at xajax tutorial and normaly this line is like that:
"6. Between your tags, tell xajax to generate the necessary JavaScript:
<?php $xajax->printJavascript(); ?>"

is this some link to xajax library? Why they use ('xajax/') instead of (). If this is link then i have to change some other things...

finaly .. i just thinking, maybe i have to just put simple mail form and forget about xajax..

you don't need to learn so much about php to use this tutorial but you need to know some basics

Hi Guys, that is my first post I hope I can find some help.
I have many difficulties running this ajax form here is my code:

<?
require_once('phpmailer/class.phpmailer.php');
require ('xajax/xajax_core/xajax.inc.php');

$form = '<form id="cform">
            <div>
              <label for="name">Name</label>
              <input name="name" type="text" id="naam" value="" size="25" />
            </div>
            <div>
              <label for="email">E-mail</label>
              <input name="email" type="text" id="email" value="" size="25" />
            </div>
            <div>
              <label for="msg">Message</label>
              <textarea name="msg" id="msg" cols="45" rows="5"></textarea>
            </div>
            <div style="border-top:1px solid #CCCCCC;padding-top:5px;">
              <label for="subbtn" style="text-align:right;"> --&gt; </label>
              <input type="button" id="subbtn" value="Submit" onclick="xajax_myFunction(xajax.getFormValues(\'cform\'));" />
            </div>
          </form>';

function myFunction($get) {
    global $form, $error;
    $error = '';
    $objResponse = new xajaxResponse();
    $show_form = true;
    if (!empty($get['email']) && !empty($get['msg']) && !empty($get['name'])) {
        if (preg_match("/^[\w-]+(\.[\w-]+)*@([0-9a-z][0-9a-z-]*[0-9a-z]\.)+([a-z]{2,4})$/i", trim($get['email']))) {
            $email = preg_replace("/\r\n/", "", $get['email']);
            $from = preg_replace("/\r\n/", "", $get['name']);
            $mail = new PHPMailer();
            $mail->IsSMTP();
            $mail->Host = "smtp.yourserver.com";
            $mail->SMTPAuth = true;
            $mail->Username = "postmaster@yourserver.com";
            $mail->Password = "password";
            $mail->From = "postmaster@yourserver.com";
            $mail->FromName = "Webmaster";
            $mail->AddAddress("admin@yourserver.com");
            $mail->AddReplyTo($email, $from);
            $mail->Subject = "contact form using Xajax and phpmailer";
            $mail->Body = $get['msg'];
            if ($mail->Send()) {
                $error = "The form is submitted and the mail is send.";
                $show_form = false;
            } else {
                $error = "There was a problem while sending the mail, please try again";
            }
        } else {
            $error = "The entered e-mail address is not valid.";
        }
    } else {
        $error = "At least one of the fields is empty...";
    }
    $data = (!$show_form) ? '<p class="contactMsg">'.$error.'</p>' : '<p class="contactMsg">'.$error.'</p>'.$form;
    $objResponse->addAssign('contact_result', 'innerHTML', $data);
    return $objResponse;
}



          ?>

But is doesnt work, here is the error message

Fatal error: Call to a member function on a non-object in /home/xxx/public_html/fmail.php on line 71


This line caused a problem for me

<?php $xajax->printJavascript('xajax/'); ?>

Any idea what is wrong

         <?php
      $xajax = new xajax();
      $xajax->registerFunction('myFunction');
      $xajax->processRequests();

      ?>
