I have a template I’m working on that needs to conditionally display a link around text depending on when it is.

Basically, I want to do this:

{if {date format="%W-23"} < week_number} link code {if:else} just text {/if}

Essentially, there’s a value in the entry called week_number, and because this particular template is for a mid-year set of data, I want to check the week number against the week of year (%W) minus 23.  So week 1 for the data is equal to week 24 of the year.

I get an error:

Parse error: syntax error, unexpected T_STRING in /web/abgclass.com/newsite/kingsarms/expressionengine/libraries/Functions.php(640) : eval()‘d code on line 36

I can’t find any documentation discussing date math. 

Thanks in advance.

You can’t add an arithmetic expression to the format of a date variable.  Furthermore, I don’t believe EE conditionals support arithmetic expressions.

You could add a bit of PHP to your template to accomplish this, or get a plugin, such as MX Calculator.  But, you’ll need to find a plugin that works within a conditional.
