Create custom field type?

[sim085]

Hello, I am trying to create my own custom field type. On google I can find many example how to add existing custom field types which come with Joomla however I am more interested in creating my own type.

So far I have tried to build my own custom field type by looking at the fields that come with Joomla. However I am getting stuck in the part where I come to display the component in the backend when setting the value of the field from an article. I can see that the code makes reference to "FieldsPlugin" however I cannot understand how this is being setup.

Using the colour picker field as an example, from the article page trying to edit this field shows a colour picker. When I check the code of the colour picker (/plugins/fields/color/color.php) I can see that "PlgFieldsColor" extends "FieldsPlugin". This is also the base class of PlgFieldsText however I can't understand what these two are doing differently so that for one it shows the colour picker while for the other it doesn't.

Does anyone know of a simple tutorial to create your own custom field type?

do you mean you wish to create a Field Group?

I created a custom group. Goto Users then Field Groups. Create the group you want then you can create the fields for that group in Users/Fields.

No not a field group but my own custom field type. For example imagine I want a date of birth picker. At the moment the field that would come close to this is the "Calendar" field. However imagine I do not want a Calendar. I want three drop downs with one drop down for day, another for month and another for year, one next to each other.

I know I can create a field group named "Date of Birth" with three drop downs but what I really want is one field with three drops downs. How would I go about and develop that?

In other words develop a new field (type) which when added this would show in the backend article field tab I would have a field with label set to "Date of Birth" (as defined by user when creating the field) and the field input part would be made of three drop downs as explained above.

Please note this is just an example; I am not looking for this plugin but rather trying to understand how I can develop such a plugin.

you could probably clone the FieldPlugin and just write what you need to do in their.
