[SOLVED] Extra fields - default value as placeholder was created by George Nasis
Hallo there!
is there any way the default value(optional) of an extra field to be displayed as a placeholder???
Of course not in the k2 item.php where the item is displayed but when a user fills a form with the extra fields
Thank you very much!

Hi. No, unfortunately you cannot do this without hacking K2.

The fie that renders the extra fields is administrator/components/com_k2/models/extrafield.php. Look out for the function named "renderExtraField".

Where the line you insert this placeholder="'.$extraField->name.'"?

The file path is administrator>components> com_k2>models> extrafield.php
For the text area field type, find this line:
$output = '<textarea name="K2ExtraField_'.$extraField->id.'" id="K2ExtraField_'.$extraField->id.'" rows="'.$active[2].'" cols="'.$active[3].'" '.$attributes.'>'.htmlspecialchars($active[0], ENT_QUOTES, 'UTF-8').'</textarea>';
Insert this line BEFORE it:
$attributes .= ' placeholder="'. $extraField->name .'"';
So the final code will be like this:
$attributes .= ' placeholder="'. $extraField->name .'"';
$output = '<textarea name="K2ExtraField_'.$extraField->id.'" id="K2ExtraField_'.$extraField->id.'" rows="'.$active[2].'" cols="'.$active[3].'" '.$attributes.'>'.htmlspecialchars($active[0], ENT_QUOTES, 'UTF-8').'</textarea>';

As mentioned in the other post you made, this will be properly added in K2 v2.11 with separate placeholder field to add whatever you want as field indicator.
