Hide empty sections with PHx

Use the following code to switch off parts of your website when no content is available. This comes in handy when those parts of your website have a background color.

[+phx:if=`[*side-content:len*]`:gt=`10`:then=`
    <div id="sideContentWithBgColor">
        [*side-content*]
    </div>
`:else=``+]

Do you know other ways to do this in modx?

the call should be like this:


the :len should be outside the if statement, it works inside but that it needs to pars it double and the else is not needed if else is empty.

@Dimmy
1. Can you post an example with :len outside the if. If you did it was automatically removed.

2. I always leave the else when coding. It's kind of a standard for readability and it's easier to update your code if something needs to be done in the else part

Hi Manu,
I prefer the len method because sometimes users will leave empty bold tags or similar in the rich textareas.

Thx for the commment
