Hey, @elliot.
First, thank you for your attention.
Actually, what I did was to copy all the code from the post I’ve added as a reference (http://support.advancedcustomfields.com/forums/topic/how-do-i-get-optgroups-in-the-select-field/) and when I created a Select Field in the Admin Panel, I added the choices like the post. For example:
-Europe
Germany
France
-South America
Brazil
Argentina
The point is that when I am trying to select the choices when I am adding a post, everything works perfectly. All the “-” choices are written as optgroup and the other choices are options, but when I am trying to display this select in my theme home page, i don’t know what kind of code I have to insert to have the same appearance as the admin panel post select.
I know if I needed just to get the choices of a common select element with no optgroup the code below will work fine, but what code should I need to insert to have the optgroup select element displayed correctly?
$field_key_xyz = "field_52e81ce100934";
$field = get_field_object($field_key_xyz);
if( $field )
{
echo '<select name="' . $field['name'] . '" id="' . $field['name'] . '">';
foreach( $field['choices'] as $k => $v )
{
echo '<option value="' . $k . '">' . $v . '</option>';
}
echo '</select>';
}
Can you help me with that?
