Displaying path to thumbnail generates PHP error

I am using the following code to display auto-generated thumbnail images:
```
{products-image}{path}_thumb/{filename}.{extension}{/products-image}
```
It is generating the following PHP errors:

A PHP Error was encountered
Severity: Warning

Message: array_merge() [function.array-merge]: Argument #1 is not an array

Filename: libraries/Functions.php

Line Number: 2585

A PHP Error was encountered
Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /codeigniter/system/core/Exceptions.php:170)

Filename: core/Common.php

Line Number: 405

Any help is appreciated.

So I figured out that it generates the error if an entry has no image. No error gets generated if all entries have images.

But that makes no sense because when there is no image, it displays nothing since I have the code wrapped in an if statement like so:
```
{if products-image}
    
        <a href="/{segment_1}/{segment_2}/&lt?php">; ?>/{url_title}"]_            {products-image}{path}_thumb/{filename}.{extension}{/products-image}_        </a>
    
{/if}
```
Any ideas why this may be happening?

Hi mediapimp,

I am sorry to hear you are running into this problem.

Are you sure that the logic does fail?

Would you mind showing me the entire template code?

Thanks,

The logic does work as the code block does not get written if there is no image.

Here is the full template code:

<body class="twocolumn">

<div id="outer">

 {embed="includes/header"}

 {embed="includes/banner" subtitle="Looking out for you with a full range of CCTV products, an exceptional warranty and more features for the money."}

 <div id="main">

  <div class="nav" id="leftnav">
   
   {exp:cat_menu:render 
    base_url="/products" 
    max_depth="3" 
    channel="products"
    category_group="1" 
    nest_categories_in_url="yes" 
    include_entries="yes"
    entries_order_by="entry_date"
    entries_sort="desc"
   }
   
  </div><!-- /#leftnav -->

  <div class="article" id="content">

   <?php $cat = CategoryHelper::instance()->get_category_for_url_title('{segment_3}'); ?>
   <?php $parent_cat = CategoryHelper::instance()->get_category_for_url_title('{segment_2}'); ?>
      
    <h2><?php echo $cat['cat_name'] ?></h2>
<p>   <br />
    <?php if (isset($cat['cat_description']) && !empty($cat['cat_description'])): ?><br />
     <?php echo $cat['cat_description'] ?><br />
    <?php endif; ?><br />
   <br />
   <br />
    {exp:channel:entries<br />
     channel="products"<br />
     disable="category_fields|member_data|pagination|trackbacks"<br />
     dynamic="off"<br />
     category="{embed:category_id}"<br />
     status="open|featured"<br />
    }</p>

<p>    <div class="productitem {switch="floatleft|floatright"}"></p>

<p>    </p><h6><?php echo $cat['cat_name'] ?></h6>
<p>     <h3 class="h4"><a href="/{segment_1}/{segment_2}/&lt?php">; ?>/{url_title}" class="noline"]{title}</a></h3><br />
     {if products-image}<br />
     <br />
      <a href="/{segment_1}/{segment_2}/&lt?php">; ?>/{url_title}"]_       {products-image}{path}_thumb/{filename}.{extension}{/products-image}_      </a><br />
     <br />
     {/if}<br />
     <br />
      <?php echo substr(strip_tags('{products-subtitle}'), 0, 120) . '...'; ?></p>

<p>      <a href="/{segment_1}/{segment_2}/&lt?php">; ?>/{url_title}" class="arrowlink"]Product Details</a><br />
    </div><!-- /.productitem --></p>

<p>    {/exp:channel:entries}<br />
     <br />
   <a href="#">back to top</a><br />
   <br />
  </div><!-- /#content --></p>

<p>  <div class="aside" id="sidebar"><br />
  </div><!-- /#sidebar --></p>

<p> </div><!-- /#main --></p>

<p></div><!-- /#outer -->

The error does not get generated if I replace

{products-image}{path}_thumb/{filename}.{extension}{/products-image}

with

{products-image}

Hey MediaPimp,

What version of ExpressionEngine are you currently running?

I wonder if this is as simple as a missing “s”.

Can you try
```
{products-image}{path}_thumbs/{filename}.{extension}{/products-image}
```
Thanks,
Shane

I’m running the latest version & build of EE.

The folder “_thumb” is not the auto-generated thumbs folder that I believe you are referring to. It is a custom folder created from the Image Manipulations in the File Manager prefs. I made the short name “thumb” so it created the folder “_thumb”.

Hi mediapimp,

I thought that was too easy.

Are you using and Add-Ons that deal with images?

For that matter, would you mind listing for me the Add-Ons that you have installed?

Please let me know.

Cheers,

I was not using any image add-ons, but since I could not get this to work without the error I had to move forward using imgSizer.

The site has to go live tomorrow and I couldn’t waste any more time on this.

The add-ons installed prior to using imgSizer are as follows:

Freeform
NSM Better Meta
Mountee
BW Required Category
Custom System Messages
Low Alphabet
Low Seg2Cat
GWcode Categories
Sherlock

I also just noticed that the File module is uninstalled. Would this need to be installed to use this functionality? I didn’t think it did.

Thanks.

Hello mediapimp,

That is really odd. File module would not need to be installed and I am really perplexed as to why this was not working. I am really sorry I could not get this one solved quickly for you. I feel bad.

If imgSizer is working for you, that’s awesome.

Is there anything else I can attempt to help you with?

Thank you,

Please don’t feel bad. These things happen.

I do appreciate your help, and although I’d love to know why it’s not working, I just had to move on.

Thanks again!
