review data before submiting

I have a form that allows users to exchange a product. Before submitting I would like to give them the option to review and confirm their exchange before submitting the form. How do I do that?

I'm guessing it's something like. create form. Form then submits to new form using "redirect" and " Pass Field Data Via Query String" This page then has a submit button.
…but that's just a theory. I have no idea how to get that to work.

Hi David,

Thanks for your solution. Its exactly what im looking for. A bit more elaboration on this would be helpful. The example in the gfrom_pre_render article uses an example of creating a form field on the go. However I am trying to populate a field that already exists, in particular a HTML content field, so what would be the format for that? Any hints or direction on this would be appreciated.

Thanks

question

So if the <?php
add_filter("gform_pre_render", "pre_render_function");
?> is added to the function .php file then what is the next step? What is the value to add to the "insert variables " section ? or am i completely off lol? instruction please for the retard ( me ) lol

let me mess with it today the 91 what is that ? the body of the post? don't know your field ids?

Hi umarglobal,

Looks like you're pretty close with that snippet you shared. One of the issues is your trying to save the loop syntax as part of the string:

[php]
$field['content'] .= foreach($form['fields'] as &$field) {;

What you want to do is something like this:

[php]
$field['content'] = '<p>Please view your details and confirm your quotation by submitting the form</p>';
$field['content'] .= '<ul>';

foreach($form['fields'] as &$field) {

    $field['content'] .= '<li>';

    if($field['id']!=91) {
        $field['content'] .= $field['label'];
    }

    $field['content'] .= '</li>';

}

$field['content'] .= '</ul>';

This just updates the syntax code so that you aren't assigning to the content string. It should now loop through all the fields and add the labels to the string. I also added in the functionality so that it will pull the value of the field from the submitted data ($_POST). That is what this bit does:

[php]
rgpost('input_' . $field['id'])

Bare in mind, this only works for simple fields. When you start getting into complex fields (aka, fields with more than one input) you'll need to add logic to get all of the POST values for that field.

Let me know how you progress from here. :)

Ok here is what im getting out of all this for my form i am getting an error on this line endif;
this should work? do i need to fix anything? and what do i put in the html variables? anything? or just put this in the funcions.php file and test?

Dose this look right please look over? lol im new but code looked like admins this should be complete script if not please school me.......

<?php add_filter('gform_pre_render_1','populate_html'); //only populating html for form id 1 - 

  function populate_html($form){

	 foreach($form["fields"] as &$field) {
		 if($field['id'] == 15):

	  $field['content'] = '<p>Please view your details and confirm your quotation by submitting the form</p>';
   $field['content'] .= '
<ul>';

  foreach($form['fields'] as &$field) {

    $field['content'] .= '
<li>';

    if($field['id']!=15) {
        $field['content'] .= $field['label'];
    }

    $field['content'] .= '</li>
';

}

  $field['content'] .= '</ul>
'

			       endif;
                }

                return $form;

        }

?>

its there the 2nd save im testing now and the form diapiers when i past into the /themes/functions.php

Scott use the code im using as that works fine, as in no errors. Just change the form and field id's as your own. The only thing which is not working is that it actually does not return the form field values!!

ok just past that between <?php?> ?? form values? meaning that its not returning the post preview ?

any luck? still no good for me i just cant get it to populate the html id 15 with the post values.

nah no dice,

Im looking to hire someone to get this solution done. The only way forward :)

Thank you for the examples but it's amazing that GF doesn't have this functionality out of box.

ah Got it!!!!!!!!!! thank you GF Support they are the best!!!!!!!!! so its all good firing on all 8 bringing back all form fields but the photos anyone have any other suggestions on the photos??

Hi

Yes so all figured out! The photo fileld are not included in the preview any idas or example's?

Dana,

Your a star * .. thanks for this.

we did test and could not get the images to show in the preview with the new example by the way.

scott, you may have to try to source out the url for the location of the image. Dont know where that is saved tho, may have to dig into the plugins core files to have a look as I have been unable to locate that in the docs.

On a further note one thing that is very important in the review section, is to not show entries that are hidden as a result of failing the conditional logic of prior fields. I have managed to not include fields that are empty but there has be a if rule which checks if a field meets its conditional logic rule and if not then it should not appear in the review section at the end.

Any help on this?

Any Luck? With bringing back the photos not the photos file name in the preview?

Any luck?

I just ran some more tests and if I use this function "Address" fields dont get submitted and are blank, does that make any sense?

I would also like to know we could hide the admin only fields using Dana's code on this page - http://www.gravityhelp.com/documentation/page/Gform_pre_render.
Also, multi select fields are only returning ‘Array’. How can I get the values out of the array?
Any ideas?

Thanks
