Hi there,

I'm getting to grips with custom templating (don't have much php knowledge). So far I have found it quite easy to print the various fields in the template (using yootheme template with UI Kit).

I have run into a snag - which is probably only a basic bit of php but not sure on the correct syntax.

I have a youtube field which is optional, as such I want to only display the following code if the field exists for the particular article (i.e. if they have not added a video it will not be displayed);

<div>
<h3>Video Instructions</h3>
<?php
echo $cck->renderField('recipe_video');
?>
</div>

I assume it would be something with the php isset command but again, no idea on the syntax!

Any help is appreciated!

Thanks in advance
Simon

The part echo $cck->renderField('recipe_video'); will only render if there is content, anyway.
If you want to test the value and not output the divs, maybe you can go with: if (strlen($cck->getValue('recipe_video')) > 0) { field display code block }

That worked a charm as such;

<!-- Start of Video -->
<?php if (strlen($cck->getValue('recipe_video')) > 0) { ?>
<div>
<h3>Video Instructions</h3>
<?php
echo $cck->renderField('recipe_video');
?>
</div>
<?php } ?>
<!-- End of Video -->

Needs a little bit of cleaning up, using the Field name instead of hard coded text etc.

Thanks for your help

Hi,

strlen works with strings only, you can use !empty for all kinds of fields like field x.

<?php if (!empty($cck->get( 'your_field_name' )->value)): ?>

<!-- Your code -->

<?php endif; ?>

Thanks for your input - that makes more sense and looks a bit cleaner too. I'll give that a shot.

Once I'm finished with my template I'll put up a post with a few snippets of code that helped me, hopefully will help some others too.

Thanks again
