Switchee regex for numbers

Question

Trying to get switchee to work with a regex check against a URL segment.

For example following URL check if segment 2 is numeric:

/property/123

Using:

{exp:switchee variable = "{segment_2}"}
    {case value="#[0-9]+#"}
        IS A NUMBER
    {/case}
{/exp:switchee} 

However this isn't working. Any thoughts/suggestions?

Cheers

Answer 1

You just need to set the parse parameter to inward if you want to discard the content of the unmatched cases before parsing them or you are using a module or plugin tag as a parameter.

The RegEx you're using, /[0-9]+/, will match strings containing a number, not being one.

Please, try:

{exp:switchee variable="{segment_2}" parse="inward"}
    {case value="#^\d+$#"}
        IS A NUMBER
    {/case}
    {case default="yes"}
        NOT A NUMBER
    {/case}
{/exp:switchee}

^\d+$ will match just numbers.

Add parse="inward" to switchee:

{exp:switchee variable="{segment_2}" parse="inward"}
    {case value="#[0-9]+#"}
        IS A NUMBER
    {/case}
    {case default="yes"}
        NOT A NUMBER
    {/case}
{/exp:switchee}
