Display extra fields in BT-Content-Slider (module) was created by Justin Thomas
I have posted the following on the BT-Content-Slider forum as well. However I feel the piece I am missing is more to do with K2 and me not understanding how to call the field into the module.
I have used the following code in the category_item.php file with success, but when taken to this 3rd party module then it does not work.
So, where am I going wrong? I have looked at a lot of forum entries "nearly" describing this, but no answer. I really hope somebody has succeeded at something like this and can help me.

<?php if($this->item->params->get('catItemExtraFields') && count($this->item->extra_fields)): ?>
<!-- Item extra fields -->
<div class="catItemExtraFields">
<?php $custom = $this->item->extra_fields; ?>
<ul>
<li>
<span style="font-family: 'Trebuchet MS', Arial, Helvetica, sans-serif;font-weight: normal;font-size:11px;"><?php echo ($custom[0]->type=='date')?JHTML::_('date', $custom[0]->value, JText::_('K2_DATE_FORMAT_LC')):$custom[0]->value; ?> from <?php echo $custom[1]->value; ?></span>
</li>
</ul> <div class="clr"></div>

Hey Justin -- I'm getting down and dirty with the extra fields myself in learning K2 (the extra fields are the exact usage scenario I'm investigating K2 for!)
Very simple question... can you verify that for this item, Extra Field [0] and Extra Field [1] both exist as items (and that [0] is a date type)?
As I'm troubleshooting this, I've found that a quick hack-and-slash way to see what I'm doing wrong is to iterate through all the extra fields and only process ones based on the text value of the field name ($myfields->name).

@justin try echo $custom[1]->value
@adam [0] is the first element of the array or first extra field and [1] is the second element of the array or the second extra field

Thank you for your reply. Both Extra Field [0] and Extra Field [1] exist and [0] is a date type. I don't think there is any issue with the call but there is something else missing. I have used this call in the category_item.php file and it has worked fine, but when I move it into the BT-Content-Slider module being called using
it doesn't work. There must be something in the headers in category_item that I am not including in my header for the default.php file for BT-Content-Slider.

William, thank you for your reply. As you will note in my original post I am using
In the body of default.php so I have the call you suggest (and a more defined call for the date with custom[0]. This call works perfectly in category_item.php but does not work in BT-Content-Slider when loaded in a
call. There is no option in the BT-Content-Slider to request the extra fields, so is there something I can put into the default.php header that will request this data so that I can call it in the <body>?
Thanks again.

OK, I got it working the way I wanted it to.
I wanted to replace intro / full text with an extrafield that I called 'Accroche' . This extrafield has an ID of 132 (useful to know the ID that will be used in code below).
We will be editing 2 files :
/modules/mod_bt_contentslider/classes/content.php
and
/modules/mod_bt_contentslider/classes/k2.php
First thing to do is get the extrafield info from database :
in /modules/mod_bt_contentslider/classes/content.php (around line 77) I added a.extra_fields, as follows
Save file & close
Now lets get to /modules/mod_bt_contentslider/classes/k2.php (around line 234),
Replace this original code
With this code that I've commented to make things understandable for noobs like me ;)
As you can see, I've commented out the intro texts as I don't want them. You can modify that if you want both introtext AND extrafield.
Hope this helps.
Cheers !
