How to get form id?

  1. Hi,
    I'm trying to create a function which will add a field to the user metadata table on form submission. I'd like that field to contain an array of all the fields/responses in the submitted form.

    I tried using the gform_post_submission action hook and setting $form_contents = $entry['field_id'] as described on this page: http://www.gravityhelp.com/documentation/page/Entry_Object

    But no go. Any ideas on how to get this working? I suspect I'm trying to get the form/field contents in the wrong way. Here's my current function:

    add_action("gform_post_submission", "set_additional_user_fields");
    function set_additional_user_fields($user_id) {
        $form_contents = $entry['field_id'];
        add_user_meta($user_id, 'form_info', $form_contents);
    }

    Thanks for your help!

  2. Hi Michelle,

    Should the entry data be added to the user submitting the form or a specific user? The gform_post_submission hook passes the $entry variable (documentation here). If the submitting user is logged in at the time of the submission their user ID will be included in the $entry in the created_by property. Here is a start:

  3. Thanks David!! That works great for getting a specific field value from the form.

    Do you know, is there any way to retrieve all the field name/value pairs in an array? I thought field_id would do the trick based on this from the entry_object page:

    FIELD_ID
    (string) The value for all submitted fields can be retrieved by using the Field Id as the key to the $entry array.

    But maybe not? Thanks again,

    Michelle

  4. Hi Michelle,

    The FIELD_ID is actually not a property of the entry object. It is listed to imply that using the field ID you can get the submitted value of the desired field (ie $entry[10]). Here is a some code that will retrieve the submitted values from the entry and aggregate them into an array (titled $submitted_info in the snippet). You can combine this code with the previously provided code.

  5. You rock!! Thank you!

    Unfortunately I had to hack a bit of the core code to get everything working just the way I needed it to, but good news is, I think I now have a way to link my saved form to a logged-in user's profile (so the user can come back and edit the form / resubmit later). In any case this is working for me. :-)

    Here's what I had to do to achieve it:

    UPDATE - see this post for a revised solution:
    http://www.gravityhelp.com/forums/topic/saving-a-form#post-32318

    1. In your form, go into each field's Advanced tab and click "Allow Field to be Populated Dynamically. Enter a parameter name - it can be anything, but should be unique.
    2. Change line 909 of forms_model.php to read:
      return apply_filters("gform_field_value_$name", apply_filters("gform_field_value", $value, $name));
    3. Add the following to your theme's functions.php file:
      // RETRIEVE PARAMETER_NAME FOR FIELDS AND ADD TO WP_USERMETA
      add_action('gform_post_submission', 'save_entry_values', 10, 2);
      function save_entry_values($entry, $form){
          $userid = $entry['created_by']; // retrieve user ID
          $submitted_info = array();
      
          foreach($form['fields'] as $field) {
      
              $value = RGFormsModel::get_lead_field_value($entry, $field);
      
              if($value) {
                  $submitted_info[] = array($field['inputName'] => $value); // retrieves parameter_names values
                  update_user_meta($userid, $field['inputName'], $value); // stores parameter_name values in wp_usermeta table
              }
          }
      }
      
      // RUN REVISED GFORM_FIELD_VALUE_YOUR_PARAMETER FILTER
      add_filter('gform_field_value', 'populate_user_meta', 10, 2);
      function populate_user_meta($value, $name){
          global $user_ID;
          $field_user_meta = get_the_author_meta($name, $user_ID);
          return $field_user_meta;
      }
    4. Now when logged-in users fill out a form, they should be able to return to that same form later and have all their previous answers pre-populated.

    The way the filter is rewritten should allow users to use both the gform_field_value filter and the original gform_field_value_your_parameter filter - the latter will overwrite the former.

    Let me know if you can think of a better way to do this - any of it - and/or if there's a way I can move that rewritten filter into my local functions.php file. I hate to edit the core code, just couldn't see a way around it in this instance.

    Thanks again for your help!
