How to fetch specific extra field selected val was created by ATHANASIOS ILIOPOULOS

I am trying to make some customizations in my:

administrator\components\com_k2\views\item\tmpl\default.php

file and to print somewhere item's extra field selected values.

In file's code i can see that i can get extra field name and element like:

<?php if (count($this->extraFields)): ?>
    <?php foreach($this->extraFields as $extraField): ?>
        <?php echo $extraField->name; ?>
        <?php echo $extraField->element; ?>
    <?php endforeach; ?>
<?php endif; ?>

however "$extraField->value" does not seem to work. It

I have also tried to access item's extra field values by using:

$extrafields = array();
foreach($item->extra_fields as $item)
{
   $extrafields[$item->id] = $item->value;
}

But "$item->extra_fields" does not seem to work at administrator item.php template of K2.

Any suggestions?

Hello there,

The syntax in the administrator template is a bit different.

$this->row->extra_fields;

is being used.

Depending on the PHP version some str_replace might be needed in order to use json_decode.

Use this snippet as a starting point.

		<?php if($this->row->id): ?>
			<?php $extra_fields = str_replace('&quot;', '"', $this->row->extra_fields); ?>
			<?php var_dump(json_decode($extra_fields)); ?>
		<?php endif; ?>

Hi Krikor,

thanks for your response, it helped! Resolved it like:

<?php if($this->row->id): ?>
    <?php $extra_fields = str_replace('&quot;', '"', $this->row->extra_fields); ?>
     <?php $extrafields1 = json_decode($extra_fields) ?>
     <?php $sample_type = $extrafields1[5]; ?>
<?php endif; ?>

and then accessing each extra field value like:

$sample_type->value

thanks!
