Hi,
I use a similar for each routine when I use the extra fields - far more useful than the default list of extra fields!
I found that moving the for each code inside the "if this item params get itemExtrafields - endif" and then moving this to the top of the template over ride file stopped this error for me - I moved it near the top as I use extra fields for sub titles galleries, plugins etc all the way through my templates!
Heres the code I use (on k2.5 - k2.6, J1.5-J2.5) it allocates just the values to a variable which can then be echo'd wherever you need in the template - can be extended to include extrafield title/name if required:

<?php if($this->item->params->get('itemExtraFields') && count($this->item->extra_fields)): ?>

<?php foreach ($this->item->extra_fields as $key=>$extraField):

switch($extraField->id) {
case 1:
$ResearchTitle = $extraField->value;
break;
case 2:
$ResearchBlock1 = $extraField->value;
break;
case 3:
$CourseVenueTitle = $extraField->value;
break;
case 4:
$CourseMapLinkText = $extraField->value;
break;
case 5:
$CoursePrice = $extraField->value;
break;
case 6:
$CourseVenueDetails = $extraField->value;
break;

}
endforeach;
?>

<?php endif; ?>


<?php if(!empty($ResearchTitle)): ?>

<span class="ResearchTitle"><?php echo $ResearchTitle; ?></span>
<?php endif;?>


Hope this makes sense/helps!

I like where you went with this... can you explain the "cases" a little more? Do they represent the different extra fields?

BTW, still getting an error.. it just DOES NOT like the foreach... sigh.. I even tried it right in the default template to make sure it wasn't something else in my code.. :S

Isn't there a way just to pull out the references to each without a for each? Seems a little redundant to have to create an array when the fields already exist..

Is there a way I can get a list of the db call/fields that K2 uses? Is there a command I would use in the code to list them? Sorry.. I am a bit weak with PHP :(

I have been researching this issue all afternoon... I have to go live with the site by May 4th and I don't have the ability currently to separate the extra fields.... so any advice would be highly appreciated.

I created this code to check that the array exists:
