Subform \ repeating rows from other tables was created by Neil

It would be a nice feature to be able to use subforms in your main form from other tables when entering \ veiwing data as in the attached image.

As a simple example lets say you have a main table of authors and another table of books. From the Authors form you would add as many books as necessary as additional rows.

Hello Neil

We know this is a very difficult and tedious task, but it's a very specific and hard to develop feature that I am not sure we could add to the Component Creator. Maybe if it get more votes we can give it a second thought.

Best regards,

Andrés.

Would be a great feature... most things have 1 to many relationship... I think that there is massive scope for 2 things that this triggers...

1) a drag and drop View Creator.
2) a configuration option so that all ADMIN and all SITE functions/classes are completely separate and not using some Admin function in the Site...

Being a developer, I understand why this request would be difficult to fulfill. There just isn't a 'boilerplate' that works for all of these situations, and a working knowledge of how your data is interconnected is a must.

However, I think a bit of information goes a long way. The basic way this works is that the data is grabbed from the database in the MODEL and stored in an ARRAY. The VIEW then displays the data using a 'FOR EACH' loop to move through the ARRAY. So to get 'sub-data' for an item the easiest way is to write the data to a 'sub-array' using another 'FOR EACH' loop.

Here's some of my code from a model that lists Board Meeting 'Committees', and the Members that are assigned to them. Board Members, Committee, and Committee Assignments each have their own table;

MODEL;

public function getItems()
    {
        $items = parent::getItems();
      
         //Retrieve the committee member assignments, assign to array.
            foreach ($items as $item){ 
               $db2 = $this->getDbo();
               $query2 = $db2->getQuery(true);
               $query2->select($db2->quoteName(array('a.member_id', 'a.title', 'b.fname', 'b.lname', 'b.image')));
               $query2->from($db2->quoteName('#__boardmgmt_commassign', 'a'));
               $query2->join('INNER', $db2->quoteName('#__boardmgmt_members', 'b') . ' ON (' . $db2->quoteName('a.member_id') . ' = ' . $db2->quoteName('b.id') . ')');
               $query2->where($db2->quoteName('a.comm_id').' = '.$item->id. ' AND '. $db2->quoteName('a.state').' = 1'. ' AND '. $db2->quoteName('b.state').' = 1');
               $query2->order($db2->quoteName('a.ordering') . ' ASC');
               $db2->setQuery($query2);
               $item->members = $db2->loadObjectList();
            }
        return $items;
    }

VIEW;

// no direct access
defined('_JEXEC') or die;
$document = JFactory::getDocument();
$document->addStyleSheet(JURI::base(). "components/com_boardmgmt/assets/css/views.css");
?>
    <?php foreach ($this->items as $item) : ?>       
        <div class="comm_box">
            <h2 class="comm_title"><?php echo $this->escape($item->title_en); ?></h2>
            <?php echo $item->desc_en; ?>         
            <div>
            <?php foreach ($item->members as $member) : ?>
               <div class="comm_member">
               <?php if ($member->image != ''): ?>
               <img src="<?php echo JRoute::_(JUri::base() . 'administrator' . DIRECTORY_SEPARATOR .'components' . DIRECTORY_SEPARATOR . 'com_boardmgmt' . DIRECTORY_SEPARATOR . 'bmimages' .DIRECTORY_SEPARATOR . $member->image, false);?>">
               <?php endif; ?>
               <a href="<?php echo JRoute::_('index.php?option=com_boardmgmt&view=detail&id='.(int) $member->member_id); ?>"> <?php echo $member->fname . ' ' . $member->lname; ?></a><br />
               <?php echo $member->title; ?>
               </div>
            <?php endforeach; ?>
            </div>
      </div>   
    <?php endforeach; ?>

Hi Nick!

Thanks for those snippets, let's see if it covers the need our guys have. We can still think about how to implement it seeing it's getting a bit popular.
