如何在Fuel CMS区块中访问传递的变量？技术咨询

Hey there, let's get your Fuel CMS block variables working. I see you're trying to pass custom variables to a block but can't access them—here are the most likely fixes:

1. Access Passed Variables Directly (No fuel_var() Needed) #

When you pass variables via the vars array in {fuel_block()}, those are available as local Smarty variables in your block template. You don't need to use fuel_var() here—that function is for global, page-level, or config variables, not the ones you explicitly pass to the block.

For example, in your nt_project_card template, replace references like {fuel_var('img')} with {$img} (if you add 'img' => 'path/to/image.jpg' to your vars array), and use your passed variables like this:

<img class="card-img-top" src="{$img}" alt="Project Image">
<div class="card-body">
  <h5 class="card-title">{$project_title}</h5>
  <p class="card-text">{$project_desc}</p>
  <a href="{$project_link}" class="btn btn-primary">View Project</a>
</div>

2. Fix Syntax in Your fuel_block Call #

Looking at your code snippet, you're using => which is HTML-encoded. In your actual template, you need to use the plain Smarty arrow =>—otherwise, Smarty won't parse the array correctly and your variables won't be passed:

{fuel_block(array( 
  'view' => 'nt_project_card', 
  'vars' => array( 
    'project_title' => 'Test Project', 
    'project_desc' => 'Some details about project', 
    'project_link' => 'projects/project1' 
  )
))}

3. Confirm Your Block View is in the Right Place #

Make sure nt_project_card.tpl (or .php if using PHP views) lives in the correct directory. Fuel looks for block views in:

• fuel/app/views/blocks/ (for custom blocks you create)
• fuel/modules/fuel/views/blocks/ (for core Fuel blocks)

If your block is in a subfolder, adjust the view path accordingly, e.g., 'view' => 'blocks/cards/nt_project_card'.

4. Debug by Printing All Variables #

If you're still stuck, add this line to your block template to see every variable available in its scope. This will tell you if your variables are even being passed:

<pre>{$|@print_r}</pre>

If you don't see project_title, project_desc, etc., in the output, go back and double-check the fuel_block syntax and view path—those are the most common culprits here.
