Category menu?

Hey Greg,

That's certainly closer, but I need to edit the ul tag created for the children, by applying the parents #ID and the class.  Would it be some additional 'ulAttributesCallback' but only applied if it has a parent?

<ul id="sidenavigation">
  <li><a data-toggle="collapse" href="#child" aria-expanded="false" aria-controls="child">Link</a>
    <ul id="child" class="collapse">
      <li><a href="">Child</a>
      <li><a href="">Child</a>
      <li><a href="">Child</a>
    </ul>
  </li>
  <li><a href="">Link</a></li>
  <li><a href="">Link</a></li>
</ul>

Hey Tim,

I think something like this will work:

<?php 
  // load STUCTURE
  list($categories, $selectedCategory) = getCategories(array(
    'tableName'              => 'structure',
    'categoryFormat'         => 'twolevel',
    'rootCategoryNum'        => '1',
    'ulAttributesCallback'   => 'customMenuUlAttr', // ADVANCED: custom function to return ul attributes, eg: myUlAttr($category);
    //'liAttributesCallback' => 'customMenuLiAttr', // ADVANCED: custom function to return li attributes, eg: myLiAttr($category);
  ));

  function customMenuUlAttr($category) {
    global $GLOBALS;

    return ($category['_hasParent'] && $category['depth'] == '1')? " id=\"child{$GLOBALS['PARENT_NUM']}\" class=\"collapse\"" : "" ;
  }


  //WE NO LONGER NEED THIS, SO I'VE COMMENTED IT OUT
  /*
  function customMenuLiAttr($category) {
  return ($category['_hasChild'] && $category['depth'] == '0')? 'data-toggle="collapse" href="#child"': "" ;
  }*/

?>
<div>
  <ul id="sidenavigation">
    <?php foreach ($categories as $categoryRecord): ?>
      <?php echo $categoryRecord['_listItemStart'] ?>

      <!-- if we're dealing with 
      <?php if ($categoryRecord['_hasChild']): ?>
        <?php $GLOBALS['PARENT_NUM'] = $categoryRecord['num']; ?>
        <a><?php echo $categoryRecord['name'] ?></a>
      <?php else: ?>
      
        <a href="#child<?php echo @$GLOBALS['PARENT_NUM']; ?>"><?php echo $categoryRecord['name'] ?></a>
      <?php endif ?>

      <?php echo $categoryRecord['_listItemEnd'] ?>
    <?php endforeach; ?>
  </ul>
</div>

So if an item has a child, we set the num value to a global called $GLOBALS['PARENT_NUM']. We can then detect the value in any function we use. 

I've then modified the UL tag function so that it will have the relevant parent num added to the child tag, by adding the parent num value where required.

Cheers,

Greg

Thanks Greg - but I'm getting an error: Notice: Undefined index: PARENT_NUM in /home/mcmahonclarkecom/public_html/structure.php on line 31 which relates to 

return ($category['_hasParent'] && $category['depth'] == '1')? " id=\"child{$GLOBALS['PARENT_NUM']}\" class=\"collapse\"" : "" ;

Hey Tim,

I'm not sure what's causing this, please could you fill out a second level support request:

Then I can add some debugging code to work out what the issue could be. 

Thanks!

Greg

Hey Tim,

Here is the final code to make a menu using bootstrap collapse (http://getbootstrap.com/javascript/#collapse) :-


// load STUCTURE
list($categories, $selectedCategory) = getCategories(array(
  'tableName'            => 'structure',
  'categoryFormat'       => 'twolevel',
  'rootCategoryNum'      => '1',
  'ulAttributesCallback' => 'customMenuUlAttr', // ADVANCED: custom function to return ul attributes, eg: myUlAttr($category);
  //'liAttributesCallback' => 'customMenuLiAttr', // ADVANCED: custom function to return li attributes, eg: myLiAttr($category);
));


  function customMenuUlAttr($category) {
    global $GLOBALS;

    return ($category['_hasParent'] && $category['depth'] == '1')? " id=\"child{$category['parentNum']}\" class=\"collapse\"" : "" ;
  }




So first we add the parent id and class to the UL tag  if we're dealing with a child item on the second level.

      <ul id="sidenavigation">
        <?php foreach ($categories as $categoryRecord): ?>
          <?php echo $categoryRecord['_listItemStart'] ?>

          <?php if ($categoryRecord['_hasChild']): ?>
            <a aria-expanded="false" data-toggle="collapse" href="#child<?php echo @$categoryRecord['num']; ?>" ><?php echo $categoryRecord['name'] ?></a>
          <?php else: ?>
          
            <a href="<?php echo $categoryRecord['_link']; ?>" ><?php echo $categoryRecord['name'] ?></a>
          <?php endif ?>

          <?php echo $categoryRecord['_listItemEnd'] ?>
        <?php endforeach; ?>
      </ul>

The above code checks if we're dealing with a parent item that has a child, and if it does adds the appropriate classes to make the link a menu collapse type.

Thanks,

Greg 

Great!  Thanks for the effort Greg!
