Hi,

I’m receiving tons of errors such as this:

A PHP Error was encountered

Severity: Warning

Message: Wrong parameter count for array_unique()

Filename: relationship_parser/Tree_builder.php

Line Number: 135

A PHP Error was encountered

Severity: Notice

Message: Undefined offset: 329

Filename: relationship_parser/Parser.php

Line Number: 52

A PHP Error was encountered

Severity: Notice

Message: Undefined offset: 337

Filename: relationship_parser/Parser.php

Line Number: 52

I’m running EE 2.7
PHP Version 5.2.6-1+lenny16

My template looks like this:

{exp:channel:entries channel="independent_faq_page"}
           
       {parents sort="desc" orderby="title" }
       <h4><a href="#">{parents:title}</a></h4>
<p>       <div class="accordionpanel"><br />
       {parents:faq_answer}<br />
       </div><br />
       {/parents}          <br />
      <br />
      {/exp:channel:entries}

Strangely, this works fine on my local environment. I have the exact same files, the exact same database, but the difference is I’m running Mamp with PHP Version 5.2.17. I have tried changing the PHP version to 5.3.14 and 5.4.4 and things work ok there too.

I can only imagine there is some bug with php version 5.2.6?

I have edited the file expressionengine/libraries/relationship_parser/Tree_Builder.php below line 497 to echo out the entry ids like so:

$field_id = $leaf['L'.$i.'_field'];
    $entry_id = (int) $leaf['L'.$i.'_id'];
    $parent_id = (int) $leaf['L'.$i.'_parent'];
    echo $entry_id; // <!-- Echo out entry ids

I then visit the same page on both staging/local.

On my staging environment the result is:

329,337,330,338,331,339,332,340,333,341,334,342,327,335,328,336,

On my local environment the result is:

327,335,328,336,329,337,330,338,331,339,332,340,333,341,334,342,

So clearly there is some disparity between the entry ids being returned on staging vs local, hence the offset errors.

I have been doing some research and someone else has found a bug with array_unique() on one version of PHP, and there was a fix. But that doesn’t work for my version it seems. Here is that solution:

Any ideas please??

I am experiencing the same problem—tried the other fix, and it did not work for me either.

The Error:

A PHP Error was encountered

Severity: Warning

Message: Wrong parameter count for array_merge()

Filename: relationship_parser/Tree_builder.php

Line Number: 133

My template code:

{exp:channel:entries channel="department" dynamic="no"}
  <h3><a name="{entry_id}" class="none">{title}</a></h3>
<p>  {career_dept}<br />
    {career_dept:parents field="career_dept"}<br />
      {if parents:no_results}NOTHING FOUND{/if}<br />
      </p><h4>{title}</h4>
<p>      {job_description}<br />
   {/career_dept:parents}<br />
  {/career_dept}  <br />
{/exp:channel:entries}

PHP Version 5.2.14

It looks like that code only supports PHP 5.2.9 and above as there is a new parameter to do with sorting in that version for array_merge - http://php.net/manual/en/function.array-unique.php

My guess with the difference with the entry_ids between staging/local is because local is working as it should but staging isn’t sorting because it’s an earlier PHP version but still working because it’s only a php warning rather than a fatal error.

You could try upgrading to EE 2.7.1 or upgrading PHP to the latest verison on staging.
