conditional css classes in fc template was created by nico65

Hi,
first of all thanks a lot for this great Component! (The best CCK I see so far)

I just play around with your template system (very easy to understand even for a non php expert like me) but how can I ask if a Field is empty or not?

I try to explain:
I have two fields in the item description template
MainImageLeft and text
Now I want to append a css class if the MainImageLeft field is empty (just to adjust the width of the text field)

I tried it like this:

Code:

<!-- BOF description -->
	<div class="description">
		<?php foreach ($this->item->positions['description'] as $field) : ?>
			<?php if ($field->label) : ?>
		<div class="desc-title"><?php echo $field->label; ?></div>
			<?php endif; ?>
		<div class="desc-content <?php echo $field->name; ?><?php if (!empty($item->name['MainImageLeft'])) : echo 'width50'; endif; ?>"><?php echo $field->display; ?></div>
		<?php endforeach; ?>
	</div>
<!-- EOF description -->

or with

Code:

if ($this->params->get('MainImageLeft') != '') : echo 'width50'; endif;

But I guess guessing takes me no further. So I would be thankfull for any tip.

Nico

Hi,
You can know it quite easily doing this :

Code:

if ($this->fields['MainImageLeft']->display) {
 do this....
}

In fact $this->item->positions is just a shortcut easier to manage for designers. It avoids them doing complex loops on the field object.
If you wish to know the complete field object structure put this in your template. This will help you a lot understanding what's inside.

Code:

<?php
echo '<pre>';
print_r($this->fields['MainImageLeft']);
echo '</pre>';
?>

Cheers,
Emmanuel.

Hi,
thanks a lot that works fine.
although just in the item template not in the category_item template.

But I will be patient and wait for the update of the template tutorial.

Hi,
It's exactly the same principle except the field object is associated to each item.
The code would be in this case for blog view

Code:

if ($this->items[$i]->fields['MainImageLeft']->display) {
do this....
}

and for the table view

Code:

if ($this->item->fields['MainImageLeft']->display) {
do this....
}

Cheers,
Emmanuel.

(Now when I see this, it looks quite logical, but when i tried to figure it out by myself I only got errors.
...I have to lern more php
