Conditional Confirmations

Last updated | Written by

This snippet is deprecated.

Gravity Forms v1.7 provides some really awesome support for conditional confirmations right out of the box. Consider this snippet deprecated.

This snippet provides the ability to specify conditional confirmations in Gravity Forms. Want to redirect users to a different page based on a value they select on the form? Or just show them a different confirmation message? This functionality will be available in Gravity Forms relatively soon, but for those of you who need this now, here is a nice an easy solution!

This snippet does not support ajax-enabled forms. Read this comment for more details.

/**
* Conditional Confirmations (with Merge Tag Support)
* http://gravitywiz.com/2012/08/18/conditional-confirmations/
*
* Provides the ability to register conditional confirmations. To register a new conditional confirmation
* use the GWConditionalConfirmations::add_conditional_confirmation() function.
*
* GWConditionalConfirmations::add_conditional_confirmation($form_id, $field_id, $operator, $value, $confirmation);
*
* @param mixed $form_id The ID of the form for which you would like to register a conditional confirmation.
* @param mixed $field_id The field ID of the field for which you would like to base the confirmation condition.
* @param mixed $operator The operator which will be used to compare the submitted field value against the specified value
* passed in the $value parameter. Accepted values are "is", "isnot", "greater_than", "less_than", "contains", "starts_with", "ends_with"
* @param mixed $value
* @param mixed $confirmation Accepted values are:
* array('redirect' => 'http:://yoururl.com')
* array('page' => 12)
* 'Plain text confirmation!'
* @param $do_init Defaults to true. Will automatically run the init which will trigger the conditional functionality when the
* form is submitted. If you would like to init on your own, you can pass false here and call the GWConditionalConfirmation::init()
* function anytime before the gform_confirmation hook is called.

How do I install this snippet?

Just copy and paste this snippet to your theme’s functions.php file.

Do I need to configure this snippet to work with my form?

Yes. First of all, you’ll want to remove the examples from the bottom of the snippet that you do not need. Next, you’ll want to either modify one of the examples to suit your needs or you can create your own.

GWConditionalConfirmations::add_conditional_confirmation($form_id, $field_id, $operator, $value, $confirmation);

  • The $form_id parameter should be the ID of the form for which you would like to register a conditional confirmation.
  • The $field_id parameter should be the ID of the field for which you would like to base the confirmation condition.
  • The $operator parameter should be the operator which will be used to compare the submitted field value against the specified value passed in the $value parameter. Accepted values are "is", "isnot", "greater_than", "less_than", "contains", "starts_with", “ends_with".
  • The $value parameter is the value to which submitted field value will be compared to.
  • The $confirmation parameter should be the type and corresponding value of that confirmation type. Acceptable values are:
    • array('redirect' => 'http:://yoururl.com')
    • array('page' => 12)
    • 'Plain text confirmation!'

Make sure you take another look at the examples too:

<?php
// example for form ID 7 where the confirmation will redirect the user to http://google.com if the value of field ID 3 is less than 10
GWConditionalConfirmations::add_conditional_confirmation(7, 3, 'less_than', 10, array('redirect' => 'http://google.com'));
// example for form ID 5 where a text confirmation will be displayed if field ID 2 is equal to "Virginia"
GWConditionalConfirmations::add_conditional_confirmation(5, 2, 'is', 'Virginia', 'Confirmed! You are from Virginia!');
// example for form ID 11 where the confirmation will redirect to the WordPress page ID 12 if the value of field ID 4 is greater than 500
GWConditionalConfirmations::add_conditional_confirmation(11, 4, 'greater_than', 500, array('page' => 12));

Summary

If you come across any bugs, let me know in the comments. Hope this proves to be a good stop gap solution until this functionality makes it into the core. :)

    Hi David, excellent work here man! I am in a similar situation as Joseph from above. I am needing the condition to be a number range rather than just 1 comparison. Have you made any progress on this addition to the snippet? This would help me so much right now.

    • David Smith says

      Hi Aaron, this snippet is deprecated. Gravity Forms 1.7 provides support for conditional confirmation right out of the box. :)

  2. Twanneman says

    One more question. I’m using a dropdown menu with values. What would the format of the merge tag be if I want the value of the merge tag? {Name :3:value} ?

    • David Smith says

      Hi Twannerman, sure thing:

      GWConditionalConfirmations::add_conditional_confirmation(7, 3, 'less_than', 10, array('redirect' => 'http://yoururl.com/?first_name={Name (First):3}'));

      If you want to make sure you get the merge tag right, just go to your form confirmation and under the “Redirect” tab, enable the “Pass Field Data Via Query String”. This will reveal a drop down of merge tags available for your query string.

  5. Craig Meiring says

    Hi, excuse my ignorance but where to I put the GWConditionalConfirmations::add_conditional_confirmation(7, 3, ‘less_than’, 10, array(‘redirect’ => ‘http://google.com’));?

    in the functions.php file or in the form somewhere?

    thanks

    • Ryan says

      Worked like a charm David.

      The “with Merge Tag Support” in your snippet and the comment above made me think the snippet in your post had been updated. Thanks for the clarification. I can confirm that the modified version worked for me with merge tags. Thanks!

    • David Smith says

      Hi Ryan, you’re correct and there was some sort of fail on my end. The snippet is supposed to have support for merge tags by default. I’ve updated the primary snippet with the merge tag support version. Thanks for pointing that out. :)

  9. Joseph says

    Hi David…

    could this be done for the animation we worked on?

    // example for form ID 5 where a text confirmation will be displayed if field ID 2 is equal to “Virginia” GWConditionalConfirmations::add_conditional_confirmation(5, 2, ‘is’, ‘Virginia’, ‘Confirmed! You are from Virginia!’);

    • David Smith says

      Hi Joseph,

      This won’t really work for the chart animation you have set up as this was configured as a page template due to all the special scripts/files required for that functionality. If you’d like to customize this, send me an email with some details and I can advise.

  10. Allan Schmidt says

    Can I send one user to Paypal and a thank you page afterwards and show another user a text message instead of sending them to Paypal with the conditional confirmations?

  11. Easton Ellsworth says

    David, a huge thanks for posting this solution. I was able to grab this snippet and use it for a client this past week. They’ve got a Gravity Forms form that doubles as a user registration form and an application to view private documents. Depending on the user’s input, the form redirects them to a page 1 (access denied) or a page 2 (access granted).

    • David Smith says

      The conditional shortcode would work well if you’d just like to display different versions of a text confirmation. However, if you want one condition to redirect the user to a URL, one condition to show them a text confirmation, or multiple different redirect URLs, the shortcode wouldn’t allow you to accomplish that.

  13. Jon says

    I have been trying to get this to work but no matter what I try instead of redirecting on the conditional statement it instead loads the second page (header included) below the form?  Any ideas.

    • David Smith says

      This snippet does not work with ajax-enabled forms. I’m not eager to invest too much effort into this script as conditional confirmations will be available natively in Gravity Forms 1.7; however, if enough people need this now I can see about adding support for ajax-enabled form.

  15. Joseph says

    How would I add more than one conditional logic

    like

    Less than 40

    &

    Greater than 30

     

    Am i being a Dumb Ass

    • David Smith says

      Hi Joseph, This snippet does not support multiple conditions. It wouldn’t be much work to add support. If this is something that would provide a lot of benefit to you, I can add it to the queue for this snippet. :)
