Pulling info from a block

Permalink
I need to access some info from an image block located on another page... I don't want to display the whole block, I just need to get the path of the image for some other user.

I know how to get the actual block:
$blocks = $page->getBlocks('Main');

But, I'm not quite sure how to pull specific info that has been set by the user.

Thanks!

Hi joemc,

Andrew answered your question in this week's Totally Random show, around 38:00

Essentially you'd want to get a page object for the other page, then fetch the blocks in the area ( for instance, "Main") then test for / select the particular block by its handle.

This thread might be helpful:

Grabbed this code directly from VortexSurfer's post:

$contentBlocks = array();
$c = new Page::getByPath('/about');
$blocks = $c->getBlocks("main");
foreach($blocks as $b) {
    if ($b->getBlockTypeHandle() == 'content') {
        $contentBlocks[] = $b;
    }
}


Hope this gets you on the right track!

Thanks for the reply. And thanks for including my question in the video!

As for your answer, though, that is the part I already know how to do... what I'm really trying to figure out is how to just pull the image path from the block ( after I've already grabbed the block )... I don't what to just grab the block and display it, as that will actually display the image. I want to grab the path of that image to use for other purposes.

Here's the code for the add/edit I'm using for the block:

<?php  
defined('C5_EXECUTE') or die("Access Denied.");
$al = Loader::helper('concrete/asset_library'); //for image fields
$ps = Loader::helper('form/page_selector', 'designer_content'); //for page link fields
?>
<div class="ccm-block-field-group">
   <h2>Property Image</h2>
   <?php  echo $al->image('field_1_image_fID', 'field_1_image_fID', 'Choose Image', $field_1_image); ?>
   <table border="0" cellspacing="3" cellpadding="0" style="width: 95%;">
      <tr>
         <td align="right" nowrap="nowrap"><label for="field_1_image_altText">Alt Text:</label>&nbsp;</td>
         <td align="left" style="width: 100%;"><?php  echo $form->text('field_1_image_altText', $field_1_image_altText, array('style' => 'width: 100%;')); ?></td>
      </tr>
      <!--
      <tr>

In my controller file, have have these functions:
public function view() {
      $this->set('field_1_image', $this->get_image_object($this->field_1_image_fID, 0, 0));
   }
   public function get_image() {
      $this->set('field_1_image', $this->get_image_object($this->field_1_image_fID, 0, 0));   
      return $field_1_image->src;
   }
   private function get_image_object($fID, $max_width = 0, $max_height = 0) {
      if (empty($fID)) {
         $image = null;
      } else if (empty($max_width) && empty($max_height)) {
         //Show image at full size (do not generate a thumbnail)
         $file = File::getByID($fID);
         $size = @getimagesize($file->getPath());
         $image = new stdClass;

So, I'm thinking I need to access the controller and call the get_image() function ( or something similar )... but, my attempts have failed.

Thanks for the help!

You need to call "getInstance()" on the block, like this:
$blocks = $page->getBlocks('Main'); //NOTE that this doesn't work for blocks inside an Area Layout! (See Page List Teasers helper code for how to do that if needed)
$images = array();
foreach ($blocks as $block) {
   if ($block->btHandle == 'your_block_handle') { //<-- Replace this with your block's handle
      $images[] = $block->getInstance()->get_image();
   }
}
print_r($array);
