Hi, I'm trying to add a confirmation screen to a "Contact Us" Quickform.

I have built a "Contact Us" forum using Quickform which works perfectly - kudos to the developers Smile

I am now struggling to figure out the best way to add a confirmation screen which pretty-prints the information that the user submitted on the previous screen and gives the user two options:

[Go Back] to the original screen to re-edit the form using the information that they have just submitted

or

[OK] to send the message.

So far I've experimented with creating a second quickform object and using that to display the submitted information and the [Go Back] and [OK] buttons, but am running into problems revalidating their input which I've used as the default values for the form.

I am using a PHP Session to pass the submitted information back and forth between these two forms via the exportValues() method.

I've had a look at the QF Controller, but that breaks the "embedability" of the QuickForm in a page as QFC uses header: to set which page the form is on Neutral

I would have recommended QFC, too. Can you please elaborate about the problems you see? In general, this should work.

Having two normal QF forms would also work, as you're already keeping the data in the session. On the second "page", you could freeze all fields before you display the form.

I am using a Dreamweaver Template to build/manage the website design and structure, so I was hoping to be able to embed the Form into the body of page without having to mess around with defining a header and footer within QFC.

OK. It sounds like I'm on the right track with this approach, as I can embed this in a Dreamweaver Templated page.

Thanks.

I'm still unsure about what problems you see here. QFC is just an extension to QF. Outputting a QFC form should be as easy as a QF form.

I get this error

Quote:
Warning: Cannot modify header information - headers already sent by (output started at F:\Eclipse Workspace\MSG Forms\qfc-test.php:135) in C:\xampp\php\PEAR\HTML\QuickForm\Action\Jump.php on line 60


with this code - it is the QFC wizard.php example with some HTML wrapped around wizard->run()

QFC appears to be issuing a redirect via the header location: paramater, which breaks the way that I want to embed the QFC in my webpage.

I built a form manager for my business using HTML_Quickform that included a confirmation screen (preview the form submission) and did not use QFC or multiple quickform objects.

I extended the HTML_Quickfrom class with my own form_manager class and overwrote the process() function to test for what kind of form submission had just occurred.

Code:

function process ($validate = true) {
      # form submission
        if ((! $validate) || $this->validate()) {
               
                # Edit user input - go back to original form with fields filled in
                if ($_POST['confirmedit'] == "Edit") {                                     
                        $this->display();
                       
                # Show user input - confirm that the user entered what they meant to enter
                } elseif ($_POST['submit']) {                       
                        $this->addConfirmMsg("Please click \"Confirm\" to complete the submission. To make changes, click \"Edit.\"");                               
                        $this->removeElement('submit');
                        $buttons[] = &HTML_QuickForm::createElement('submit', null, 'Confirm', array("style"=>"width: 85px;"));
                        $buttons[] = &HTML_QuickForm::createElement('submit', null, 'Edit', array("style"=>"width: 85px;"));
                        $this->addGroup($buttons, 'confirmedit', null, '&nbsp;');
                        $this->displayPreview();
                       
                # Submission confirmed  - write to DB (,send emails), show status msg         
                } elseif ($_POST['confirmedit'] == "Confirm") {
                        //Submission confirmed. Write to DB or send emails etc
                        // ...
                }
        }
}

        # Function:  previewSubmission()
        # Displays user input for confirmation (user input saved in hidden fields)
        function displayPreview() {
                $this->freeze();
                $this->display();
        }

Hi beowulf2128

thanks for the sample code. I'll have a look at that and see if I can get it working on my form - I'd given up on the confirmation screen Embarassed

Yippeee! I got it working Smile

Didn't need to overload HTML_Quickform process function, I just adapted your example code slightly and added it to the section of code that calls the QuickForm output (rendering).

Code:


##
## put your code to create QuickForm Elements, Rules & Filters here
##

if ($form->validate()) {

   # Edit user input - go back to original form with fields filled in
    if ($_POST['confirmedit'] == "Edit") {
     $form->accept($renderer);
     echo $renderer->toHtml();
   
    } elseif ($_POST['submit']) {                       
          // show the user the confirmation screen, with the option to go back and edit their information
                           
        $form->removeElement('submit');
         
        $buttons[] = &HTML_QuickForm::createElement('submit', null, 'Confirm', array("style"=>"width: 85px;"));
        $buttons[] = &HTML_QuickForm::createElement('submit', null, 'Edit', array("style"=>"width: 85px;"));
        $form->addGroup($buttons, 'confirmedit', null, '&nbsp;');
         
        $form->freeze();
        $form->accept($renderer);
     echo $renderer->toHtml();
         
     # Submission confirmed  - write to DB (,send emails), show status msg         
    } elseif ($_POST['confirmedit'] == "Confirm") {

       // Submission confirmed. Write to DB or send emails etc
       $form->process("msg_sendmail", true);

    }

} else {

   $form->accept($renderer);
   echo $renderer->toHtml();

}


Many thanks for making the effort to register and share your code!

* I am using the DHTMLRulesTableless version of QuickForm, so the following PHP code is used to produce the QuickForm HTML & Clientside Javascript Code

Code:

$form->accept($renderer);
echo $renderer->toHtml();
