Prepopulate multiple columns list field with gform_pre_render

  1. Hi.
    I am trying to prepopulate a multiple columns list field with gform_pre_render. It's causing me some grief, cause I can add value to the $field['defaultvalue'], but only the first column is filled. The rest of the columns I cannot prepopulate.

    I am using this plugin: http://wordpress.org/extend/plugins/gravity-forms-update-post/, but the plugin does not fill out list field with multiple columns and I am just trying to fix the plugin, so I can use it and send the result to the author.

  2. Hi again.

    Is it not possible to prepopulate a list field with gform_pre_render filter hook?
    I simply want to fill the fields in this list field:

    Or is it so simple, that I am just staring blind at it? :-)

  3. I'm not sure how to do it exactly, but can you try a couple things? How about dumping the $form or $entry after filling in a multiple-column list field like that, so you can get an idea of how to reference those particular fields/columns? Sometimes that's all it takes to figure out the proper syntax or 'trick' to it. If that does not help, I will try it myself or ping the developers to see if they have any insight.

    Also, take a look at this post from developer David Smith describing how the data is stored:

  4. Hi Chris.
    Thanks for getting back to me on this. :-)

    Yes, I have studied the $form/$entry dumb on this and I can't get it right.
    Here is part of the dump for this field:
    https://www.box.com/shared/b3ab15c81c754e62ddb8
    I have tried to add data to the "defaultvalue", but this doesn't help.

    Any clue?

  6. I can fill the first input field in the list field, when I convert the string to an array. Here you can see two ways I have manipulated the string and added it to the $field[defaultvalue].

    I just can't seem to fill out all three input fields.

    Hi Vayu
    what modifications did You make to get the first fields populated?

    I modified the plugin to but can't display any values in the fields.

  8. Hi.

    It was difficult task, but I think I managed to solve it. It may not be pretty and most likely it can be done better but here it is. I had to modified file gravityforms-update--post.php, which I usually don't do. This was at about line 239.
    http://pastie.org/4379397

    Furthermore, I added this bit of code to about line 170.

    elseif ($field['type'] == 'post_custom_field' && isset($meta[$field['postCustomFieldName']]) && $field_type == 'list')
            {
              $field = $this->gform_populate_element($field, $field_type, $meta[$field['postCustomFieldName']]);
            }

    I haven't explained the code, as I don't really have the time, but I hope this makes sense. :-)

    Hi,
    I had similar code like You in line 170, after adding the "list" case in the switch statement - I still have no data in the form fields.

    Here is a array for the $result array

    http://pastie.org/4379717

    but still no data in the form fields

    Hi Vayu,
    I would be very grateful if You could post the result of the

    print_r( $field[ 'defaultValue' ] );

    for the list type field?

    Thanks!

  11. This is for a list field with multiple columns:

    [defaultValue] => Array (
                [0] => Array(
                        [Column 1] => 111
                        [Column 2] => 222
                        [Column 3] => 333
                    )
                [1] => Array (
                        [Column 1] => 444
                        [Column 2] => 555
                        [Column 3] => 666
                    )
            )

    This is for a list field without multiple columns:

    [defaultValue] => Array(
                [0] => 777
                [1] => 888
                [2] => 999
           )

    I have found an issue though. For some reason it is not possible to delete entire rows, by clicking on a minus button and then update.

    Thank You!,
    I get the exact same array structure for the $form['defaultValue'] but the list fields remained empty and the thing was I had left the checkbox "Allow field to be populated dynamically" checked.

    After I unchecked it I get the fields populated, but now I have the problem with duplicating fields when updating the post.

    Here is the code I used

    Thanks again!

    I eliminated the doubling by extending this piece of code in the gform_post_data() function

    http://pastie.org/4382382

    this way if it is a list type field it deletes all the custom meta associated with this field and adds new entries.
