Hi again,
thanks for this. With my very limited knowledge of php I came up with this:

Code:

<ul class="hotel-carousel__items list-bare js-hotel-carousel">
<?php
FlexicontentFields::getFieldDisplay($item, "field_slideshow");
$field_id = 36;
$fvals = $item->fieldvalues[$field_id];
$img = $item->fields['field_slideshow']->thumbs_src['large'];
if (!empty($fvals)) foreach ($fvals as $v) {
if ( @unserialize($v)!== false || $v=== 'b:0;' ) $v = unserialize($v);
echo '<li class="hotel-carousel__item"><img src="l_'.$v['originalname'].'" ';
echo 'alt="'.$v['alt'].'" class="hotel-carousel__img"></li>';
}
?>
</ul>

What this code lacks is the full path to each image.

What I also tried is this:

Code:

<ul class="hotel-carousel__items list-bare js-hotel-carousel">
<?php
FlexicontentFields::getFieldDisplay($item, "field_slideshow");
$field_id = 36;
$fvals = $item->fieldvalues[$field_id];
$img = $item->fields['field_slideshow']->thumbs_src['large'];
if (!empty($fvals)) foreach ($fvals as $v) {
if ( @unserialize($v)!== false || $v=== 'b:0;' ) $v = unserialize($v);
foreach ($item->fields['field_slideshow']->thumbs_src['large'] as $img) :
echo '<li class="hotel-carousel__item"><img src="'.$img.'" alt="'.$v['alt'].'" class="hotel-carousel__img"></li>';
endforeach;
}
?>
</ul>

But for each alt attribute I get the entire set of images (instead of 7 images with 7 different alt attributes I get 7 images with the first alt, then 7 with the second alt, etc).

Could you provide some assistance with this? I'm in serious php pain right now...
Thanks,
Agata

Hello

you have 2 arrays and 1 array

-- so try using 1 index e.g. $nn to access both

example (not tested)

Code:

FlexicontentFields::getFieldDisplay($item, "field_slideshow");

$field_id = 36;
$fvals = $item->fieldvalues[$field_id];

$thumbs = $item->fields['field_slideshow']->thumbs_src['large'];

if (!empty($fvals)) for($nn=0; $nn < $fvals.length; $nn++) {
  $v = $fvals[$nn];
  if ( @unserialize($v)!== false || $v=== 'b:0;' ) $v = unserialize($v);
  $thumb = $thumbs[$nn];
  

  echo '<img src="'.$thumb.'" alt='.$v[alt].'"' />';
}

Hi,
I'm trying to do the same within the flexicontent universal content module but I'm not getting the alt atribute, it's as though there was nothing in the $item->fieldvalues. My code is:

Code:

<?php
FlexicontentFields::getFieldDisplay($item, "field_dest_gallery");
$field_id = 72;
$fvals = $item->fieldvalues[$field_id];
$slideshow = $item->fields['field_dest_gallery'];
$thumbs = $slideshow->thumbs_src['large'];
for ($i = 0; $i < count($thumbs); $i++) :
$v = JArrayHelper::getValue($fvals, $i);
if ( @unserialize($v)!== false || $v=== 'b:0;' ) $v = unserialize($v);
?>
<img
     src="<?php echo $thumbs[$i]; ?>"
     alt="<?php echo $v['alt']; ?>"
/>
<?php endfor; ?>

I am getting Notice: Undefined property: stdClass::$fieldvalues

Any help greatly apreciated.

Hello

for universal module the actual content item are in:
...->_row
did you print

so inside the universal module template if the current content object is named "$item"
then use:
$item->_row->fieldvalues
