Value hidden field based on user group

Hi,

Is it possible to make a hidden field in the form. Based on the user group of the logged in user the content must be changed.

For example Usergroup A has access to category 1,2 and 3.
Usergroup B has access to category 3 and so on.

The value of the hidden field should be 1,2 and 3 for usergroup A. The value of the hidden field should be 3 for usergroup 3.

I have no idea how and if this is possible at all. I hope someone can help me.

Hi Liggie,

You can do this using Custom Code - the code to get a user's groups (two versions) has been posted in this thread.

Note that in Joomla! 3 a user can belong to several groups so your PHP will need to handle that.

I think I managed to load the requiered user information. This is a screencopy of my form: Data Array

Array
(
    [option] => com_chronoforms5
    [chronoform] => zoekformuliertest
    [Itemid] => 0
    [0] => Array
        (
            [user_id] => 593
            [group_id] => 2
        )

    [1] => Array
        (
            [user_id] => 593
            [group_id] => 16
        )

    [2] => Array
        (
            [user_id] => 593
            [group_id] => 21
        )

)

But now I'm completely stuck. I would like to use the group_id to determine if a checkbox (or dropdown value) has to be checked or not. So for example checkbox A has to be checked automically if user belongs to group_id 21. Could you please give me a hint how to accomplish this?

I need the values in group_id (multiple values possible). I know that I first have to have it in an array, but what is the next step now. For example how can I show these values in my form or use it in a hidden field?

Hi Liggie,

Hmmmm . . . I've not tried this before but I think it should work. In the Form On Load event after the Custom Code to get the groups you can set appropriate values in the $form->data array and they ChronoForms will set the corresponding selections/checkboxes. I can't work out quite what format you've got the Group data in - the array doesn't seem to have a name :-(

Assuming that you have an array like this instead:

 groups => Array (
   [0] => Array
        (
            [user_id] => 593
            [group_id] => 2
        )

    [1] => Array
        (
            [user_id] => 593
            [group_id] => 16
        )

    [2] => Array
        (
            [user_id] => 593
            [group_id] => 21
       )
   )
)

The you can convert this to a simpler format:

$group_array = array();
foreach ( $form->data['groups'] as $v ) {
  $group_array[] = $v['group_id'];
}

Then set the values like this:

if ( in_array('21', $group_array) ) {
  $form->data['select_name'] = 'xxx';
}
?>

Bob

Hi thanks for your reply! Maybe very stupid but how do I give a name to the array? I use dbloader to retrieve the group_id for the logged in user. I see no fields in the dbloader where I can give it a name.

Hi Liggie,

I assume that this is the DB Multi Record Loader action? If so then please try adding a Model ID e.g. groups

Bob

No I use single db record loader with the following condition:

<?php
$user = JFactory::getUser();
return array("user_id" => $user->get("id"));?>

I turned Model Id on, now I get this result, is the correct?

Array
(
    [option] => com_chronoforms5
    [chronoform] => zoekformuliertest
    [Itemid] => 0
    [user_id] => 166
    [groep] => Array
        (
            [0] => Array
                (
                    [user_id] => 166
                    [group_id] => 7
                )

            [1] => Array
                (
                    [user_id] => 166
                    [group_id] => 8
                )

        )

Hi Liggie,

That looks good. Which version of ChronoForms are you using? The forum info under the post says CFv4 but the code looks more like CFv5?

Bob

I started with v4, but switched to v5. Thanks for helping, I'm going to try the code you suggested and will let you know if it works.

I tried this code, but is does not seem to do anything.

$group_array = array();
foreach ( $form->data['groups'] as $v ) {
  $group_array[] = $v['group_id'];
}

This is the result:

Data Array

Array
(
    [option] => com_chronoforms5
    [chronoform] => zoekformuliertest
    [Itemid] => 0
    [user_id] => 166

        (
            [0] => Array
                (
                    [user_id] => 166
                    [group_id] => 7
                )

            [1] => Array
                (
                    [user_id] => 166
                    [group_id] => 8
                )

        )

)

Hi Liggie,

The first half of the code doesn't do anything useful on its own, you need to add the second part as well - but amended to do what you need it to do.

Bob

It works for one value, but not if I add a second one. Is it possible to select multiple checkboxes based on the values in groups?

<?  $group_array = array();
    foreach ( $form->data['groups'] as $v ) {
      $group_array[] = $v['group_id'];
    }

    if ( in_array('7', $group_array) ) {
      $form->data['Repertorium'] = '0';
    }

  if ( in_array('8', $group_array) ) {
      $form->data['Repertorium'] = '1';
    }

    ?>

Hi Bob,

You're the best! It works. Thanks for your support. I could not have figured this out by myself or maybe in a year or so 😉 .
