Re: [jgen] Joomla 2.5 custom form field type problem

[Olivier Nolbert]

Hi,

If your 'City' field correctly displays the select list with 1 option, I think your custom field class is correctly set.

What you could check is if your field name is correct in the form html code and if it's the same name in the DB table.

I am developing Joomla component, and i need custom form field type (Joomla 2.5) in admin area, but i have problem... It just won't work. Here is what i done so far:

File: /administrator/components/com_mycomponent/models/forms/history.xml

<form>

<fields addfieldpath="/administrator/components/com_mycomponent/models/fields">

<field

name="id"

type="hidden"

default="0"

required="true"

readonly="true"/>

<field

id="someid"

name="someid"

type="City"

label="City"

description="Choose City"

required="true" />

</fields>

</form>

File: /administrator/components/com_mycomponent/models/fields/history.php

<?php

defined('_JEXEC') or die('Restricted access');

jimport('joomla.form.formfield');

class JFormFieldCity extends JFormField {

protected $type = 'City';

// getLabel() left out

public function getInput() {

return '<select id="'.$this->id.'" name="'.$this->name.'"> <option value="1">City 1</option> </select>';

}

}

And that is all i have changed. I use this tutorial: http://docs.joomla.org/Creating_a_custom_form_field_type (it is for Joomla 1.6, and i cant find anything "fresh"). Can someone tell me if i need more code somewhere or is something wrong with this code? (this code outputs just input field, and when i change value and save it, i can see that it is not saved in database).

Hi Oliver,

Thanks for your reply. In the meantime i found other, much simpler solution: http://docs.joomla.org/SQL_form_field_type

I wanted to call select box options from database anyway, so this is great solution for my needs.

Rename history.php to city.php that should do the trick.

Glad I could help. 

A debugger is extremely helpful! Silly errors like that will drive you bananas!
