mainupating a variable in template before using in vb each

Sample code:

HTML Code:

<vb:if condition="$first_item = X($myvar)">

        <!-- do something -->

</vb:if>

<vb:each from="myvar" key="k" value="v">

        <!-- do something -->

</vb:each>

I tried array_shift(), each() methods in place of X. Doing so causes this error.

Code:

Warning: Invalid argument supplied for foreach() in [path]/includes/functions.php on line 3555

Anyone have any idea how to workaround this?

PS: I'm aware of the counter workaround in vb:each but that doesn't go well with how I wanna write the template.
The only workaround I can now think of array_shift the value in the actual php code (rather than in template) before registering the variable to the template which is something I wanna avoid.

btw, you'll need to add this plug in to use these functions:
hook: template_safe_functions
code: $safe_functions[] = 'each';

I tried it using array_shift and it seems to work.

Code:

$myvar = array('First', 'Second', 'Third');



$templater = vB_Template::create('test_template');

$templater->register('myvar', $myvar);

print_output($templater->render());

Code:

<vb:if condition="$first_item = array_shift($myvar)">

    First: {vb:raw first_item}<BR/>

</vb:if>

<vb:each from="myvar" key="k" value="v">

    Loop: {vb:raw k} {vb:raw v}<BR/>

</vb:each>

although I think you lose the original array keys when doing it that way.

I couldn't see how you could get to fetch_error_array() with $errors not an array unless maybe you have a plugin that changes $errors (maybe using hook template_compile?) or maybe a custom tag.

I think it has to do with my array being multi-level :/
