How do I show or hide an item depending on the result of two different factors, such as field values in a single select/query?

Show the div if either query.field1 OR query.field2 has a value

Note, in my case I've got a table of racing fixtures and for each row in the table I want to link to a results page for but only if a results pdf or a report pdf is available for that particular racing fixture.

My code so far for the repeating row is below, but it's not working at the moment:

<tr dmx-repeat:repeatfixtures="">
<span dmx-show="fixturedate2"> - {{fixturedate2}}</span></td>
<td><a href="" title="Dowload Entry form for Round {{fixtureround}}" dmx-show="entryform" dmx-bind:href="./datafiles/fixturefiles/{{entryform}}">download now</a><span dmx-hide="entryform">not available</span></td>

<!-- the table cell below - I'm trying to show if either of two query fields has a result -->

<td><a href="" title="view results/reports for Round {{fixtureround}}" dmx-show="reportfile OR resultfile" dmx-bind:href="series_fixture_results.php?fixtureid={{fixtureid}}&seriesid={{seriesid}}">view results/reports</a><span dmx-hide="reportfile OR resultfile" >not available yet</span></td>


thanks in advance

Could somebody get in touch with me about this?

I'm behind in my project schedule. I really need to know how to do this for my client.

Hi Bruce,

You can enter as condition any javascript expression (or use the data formatter to generate one)
So logical operators are && for AND and || for OR

In your case you can write: query.field1 || query.field2

dmx-show="reportfile || resultfile"

or compare with some value:
dmx-show="reportfile == 'somevalue' || resultfile == 'other'"

Thanks George

I've got the data formatter but it doesn't say anywhere how to generate the javascript for this. Can you link me to a guide for it?

In the mean time I've just edited the source code so, replacing 'OR' with '||' to read dmx-show="reportfile || resultfile" and that's got it working on the page, thanks for that

Hi again

Did you get my earlier question about data formatter?
How do I use it to generate the javascript to do this again?
