Remove element by value from array

Permalink
Hello everyone,

I want to remove an element by value from the $blockTypes array.

The block_area_add_new.php is containing this code:

if (count($blockTypes) > 0) { 
      foreach($blockTypes as $bt) { 
         $btIcon = $ci->getBlockTypeIconURL($bt);
         ?>   
         <li class="ccm-block-type ccm-block-type-available">
            <a onclick="ccmBlockTypeResetKeys()" dialog-on-destroy="ccmBlockTypeMapKeys()" class="dialog-launch ccm-block-type-inner" dialog-on-close="ccm_blockWindowAfterClose()" dialog-modal="false" dialog-width="<?php echo $bt->getBlockTypeInterfaceWidth()?>" dialog-height="<?php echo $bt->getBlockTypeInterfaceHeight()?>" style="background-image: url(<?php echo $btIcon?>)" dialog-title="<?php echo t('Add')?> <?php echo $bt->getBlockTypeName()?>" href="<?php echo REL_DIR_FILES_TOOLS_REQUIRED?>/add_block_popup.php?cID=<?php echo $c->getCollectionID()?>&btID=<?php echo $bt->getBlockTypeID()?>&arHandle=<?php echo urlencode($a->getAreaHandle())?>"><?php echo $bt->getBlockTypeName()?></a>
            <div class="ccm-block-type-description"  id="ccm-bt-help<?php echo $bt->getBlockTypeID()?>"><?php echo $bt->getBlockTypeDescription()?></div>
         </li>


This code is handling all the addons in the "Add Block" list.

I want to remove the element with the value where $bt->getBlockTypeName() is "HTML" from the $blockTypes array.
Is that possible ?

So far I have been trying doing this by using this function:
unset($blockTypes["1"]);


But this function removes elements by array index. This is a problem because if I add a new addon, this function might remove the wrong addon.

Solution:

A filter. :)

foreach($bt as $key => $value) {
        if ($value == 'Content' || $value == 'HTML')  {
