Use array from plugin in template as conditional

[tbworld]

Here is some conditional usage that you may want to ponder. Of course all of this can and maybe should be done in PHP, but sometimes this is more fun. I discovered quite a few interesting things when enhancing the template system.

One of the things I modified in the template system is a 'break' for the 'each' conditional. I am pointing this out, because in the crazy example below the routine continues to iterate the array and we may have already found our resultant.

 Iterates an array for basically no reason, and if a value was found in the array
 the create a new variable inside the template for altering a dynamic response. (tbworld method)

<vb:each from="show" key="show_key" value="show_value">
    <vb:comment>
      <!-- Just to show usage -->
      key:   {vb:var show_key}  <br>
      value: {vb:var show_value}<br>
    </vb:comment>

    <!-- Check for existance of key in $show -->
    <vb:if condition="array_key_exists('member', $show)  AND  (!isset($newvar))">
        <div>Array Key Exists!</div>

        <!-- create or set a value to a variable --> 
        <vb:if condition="$newvar='Yes we created a new variable $newvar!'"></vb:if>
    </vb:if>  
</vb:each>

<!-- Display the new variable we just created -->
<dl>
   <dd>Did we create a new variable?</dd>
   <dt>{vb:raw newvar}</dt>
</dl>

<!-- --------------------------------------------------------------- -->

<!-- Key exists if not NULL -->
<vb:if condition="isset($show['member'])">--isset test --<br /></vb:if>  

<!-- Expansion on the above examples, Use with caution! -->

<!-- Create a new Array -->
<vb:if condition="$new_array = array('member', 'fruit', 'fish')" ></vb:if>

<!-- Create a new Key field variable  -->
<vb:if condition="$new_test_key='member'"></vb:if>

<!-- Create a variable resultant --> 
<vb:if condition="$resultant=in_array($new_array[$new_test_key], $show, false)" >Test Key exist in $show array<br /></vb:if>

Have fun.
