Hi.

I try to find out how to create a new extrafield-type. In my example i need an extrafield which do an sql-query and give me the result as a dropdown, similar to the JoomlaCore-Fields: docs.joomla.org/J3.x:Adding_custom_fields/Sql_Field

Does anybody know which files I have to change (or create new)?

Thanx

Or - where can I change the output of "$extraField->element"?

I just need the pure value without the generated input-field/HTML-Tag.

Thanx for the answere.

I solved it with a dirty workaround like this to output just the value (from field id 55) without the generated input-field/HTML-Tag.

$LabelName = explode("<input type=\"text\" name=\"K2ExtraField_55\" id=\"K2ExtraField_55\" value=\"", $custom_field->LabelName->element);
$LabelName = explode("\"", $LabelName[1]);
$LabelName = $LabelName[0];

With this I could create a db-output for a custom dropdown (with the previous valueselected)

<option value="<?=$singleOrganisation[1]?>"<? if ($singleOrganisation[1] == $LabelName) { echo " selected=\"selected\""; } ?>><?=$singleOrganisation[1]?></option><? } ?>
