Merging arrays in a template

[unixman]

Quick templating question. In the template markup below, I create a new array called "testArr", and attempt to populate it by calling array_merge. The first debug statement shows a properly initiatlized array with 0 elements in it. The second debug statement shows that "fields" is populated during each iteration of the loop. But for some reason, the debug statement at the end shows a NULL value for the final array. Any ideas? Thanks in advance!

    {vb:set testArr, {vb:php array}}
    {vb:debugvardump testArr}

    <vb:each from="userInfo.customFields" key="category" value="fields">
        {vb:debugvardump fields}
        <vb:each from="fields" key="name" value="field">
          <vb:if condition="$category != 'default'" >
              {vb:set testArr, {vb:php array_merge, testArr, field}}
          </vb:if>
        </vb:if>
    </vb:each>

    {vb:debugvardump testArr}

Also, the docs mention that you can use "array()" with "vb: php". I had to remove the parentheses to get it to work at all. FYI!

Cheers.

The inner <vb:each> loop has wrong closing tag <vb:if>. I don't know if that's just a typo in your post.

You're using array merge but $field variable is not an array, right? If it was, then the code should have been:

{vb:set testArr, {vb:php array_merge, {vb:raw testArr}, {vb:raw field}}}

Either way, you don't need array_merge. You could simply do this to push $field to the $testArr array.

{vb:set testArr[], {vb:raw field}}

Also make sure that your if-condition for checking $category evaluates to true.

Thanks for the response! Yes, that vb: if is actually an else. Was a typo in the post. Will try your suggestions - thanks!

yep - array_push did the trick!
