Block Layout Anomolies

<xar:set>

• variables should not contain hyphens, probably gets confused with a minu sign in the php.
• content between the <xar:set> and </xar:set> is plain ol' php
• to set an array <xar:set name="arr">array( 'key1'=>$value1, 'key2'=>$value2 )
• to modify an existing array <xar:set name="asdf">1; arr['key1']=$value3;</xar:set>

 Array key

• if BL rejects an array reference, remove the single quotes around the key value, such as <xar:image-resize src="$img_file[fileId]"

Embedding php

These are hacks for embedding php in the template. Note, this is not advised or 'supported', and I do it probably alot more often than I should. But sometimes practical implementation now trumps style and future maintenance (I'll pay dearly for this later, I know). Either of the following will work:

• <xar:set name="asdf">1; [normal php code here]</xar:set>
• <xar:if condition="[normal php code here]"></xar:if>
