Dynamically populate checkboxes

I'd like to have, based on the URL that the form is embedded on, dynamically populate the checkbox field.

The net effect I want is that if the user arrives on /contact/ it wouldn't check the box for "trouble ticket", but, if they went to /report-an-issue/ it would.

Is there any way to do that?

You rock!

Silly question, where did you put the code? I'm guessing the page template file?

cool.. Thanks!

Hi Mobi,

Can you share a screenshot of how you have your checkbox field setup?

In regards to your other questions:

1 - add_filter() is correct; add_action() will still interpret this as a filter and work appropriately, but it was just a typo in my code.
2 - We are very close to releasing the new documentation which has extensive coverage of all the available Gravity Form hooks (even the GF Add-ons!). Sorry for the wait, but just a little longer now. :)

@webpuzzlemaster:

I was in a very similar situation and solved the problem like this. This code is placed inside index.php

//Give every link an ID (in my case it was post ID as I show all posts on one site) and add it at the end of the url as query string
$addLink = get_page_link(16)."?ref=".$post->ID;
echo "<div class='add'><a href='$addLink'>A link to the form</a></div>";

I then could get the parameter value on the site where the form was placed and use it to prepopulate certain fields with values from the post I was referring to in the link. For example (code inside functions.php):

// populate category
add_filter("gform_field_value_record_link_category", "usr_populate_record_link_category");
function usr_populate_record_link_category(){
  $ref_id = $_GET['ref'];

  if(isset($ref_id)){
    $post = get_the_category($ref_id);
    $category = $post[0]->cat_ID;
    return $category;
  }
}

// populate title
add_filter("gform_field_value_record_link_title", "usr_populate_record_link_title");
function usr_populate_record_link_title(){
  $ref_id = $_GET['ref'];

  if(isset($ref_id)){
    $post = get_post($ref_id);
    $title = $post->post_title;
    return $title;
  }
}

// set parent post
add_filter("gform_post_data", "usr_set_post_parent", 10, 2);
function usr_set_post_parent($post_data, $form){
  $ref_id = $_GET['ref'];

  if($form["id"] == 1){
    $post_data["post_parent"] = "$ref_id";
  }
  return $post_data;
}

Hope this helps.

Hi Kubante,

The method you're using would select that option by default if the value exists; however, to add "new" values or overwrite the existing values in a drop down, take a look at this approach:

http://www.gravityhelp.com/documentation/page/Dynamically_Populating_Drop_Down_Fields

I even tried using new WP_Query. Solved one problem, another one came up! Again, driving me crazy. :)

Now i can filter correctly the languages i want, but unfortunately, only one post is paginated!

http://codex.wordpress.org/Class_Reference/WP_Query

is explaining that

Pagination Parameters

showposts (int) - number of post to show per page. Deprecated as of Version 2.1 in favor of 'posts_per_page'.
posts_per_page (int) - number of post to show per page (available with Version 2.1). Use 'posts_per_page'=>-1 to show all posts. Note if the query is in a feed, wordpress overwrites this parameter with the stored 'posts_per_rss' option. To reimpose the limit, try using the 'post_limits' filter, or filter 'pre_option_posts_per_rss' and return -1

Unfortunately this doesn't work. I am not able to override neither with post_limits nor with pre_option_blabla returned to -1.

I also noticed that the form field is now not anymore editable via the wysiwig Gravity forms section in wp-admin. Which is not a big issue for me, I wouldnt need to edit anything anymore for this field from the wysiwig, if it worked. :)

Any idea?

my retrieval code looks like this at the moment:

$args = array(
	'tax_query' => array(
		array(
			'taxonomy' => 'languages',
			'post_limits' => -1,
			'field' => 'slug',
			'terms' => 'deutsch'
		)
	)
);

$posts = new WP_Query( $args );

As said, correct filtering, but only one post title retrieved.

any help super appreciated.

regards,

kubante
