Help creating my own field type
Development and Programming
I want to create a new field type - a basic textarea with a button, when the user taps the button they get a pop-up allowing them to select from a drop down some text that will be pasted into the textarea.
I have been following the module development documentation here: http://ellislab.com/expressionengine/user-guide/development/modules.html#the-tab-file-tab-module-name-php but quickly get lost on the tab file, control panel and the core module. I’ve had a look around the forums and done a general google search looking for help with how to proceed. Can anyone help to guide me the right direction?
So far I have my update file:
<?php if ( ! defined('APP_VER')) exit('No direct script access allowed');
class Textarea_paster_upd {
var $version = '0.1';
function __construct()
{
$this->EE =& get_instance();
}
function install()
{
$data = array(
'module_name' => 'Textarea_paster' ,
'module_version' => $this->version,
'has_cp_backend' => 'y',
'has_publish_fields' => 'y'
);
$this->EE->db->insert('modules', $data);
/*Optionally add the publish page tab fields to any saved publish layouts. This is ONLY used if the module adds a tab to the publish page and it requires the tabs() function:
$this->EE->load->library('layout');
$this->EE->layout->add_layout_tabs($this->tabs(), 'textarea_paster');*/
}
function update($current = '')
{
if (version_compare($current, '0.1', '='))
{
return FALSE;
}
if (version_compare($current, '0.1', '<'))
{
// Do your update code here
}
return TRUE;
}
function uninstall()
{
// remove row from exp_modules
$this->EE->db->delete('modules', array('module_name' => 'Textarea_paster'));
// drop the exp_wygwam_configs table
$this->EE->load->dbforge();
$this->EE->dbforge->drop_table('wygwam_configs');
return TRUE;
}
}and my language file:
<?php if ( ! defined('APP_VER')) exit('No direct script access allowed');
$lang = array(
// Required for MODULES page
'my_module_module_name' => 'Textarea Paster',
'my_module_module_description' => 'Textarea Paster adds a new fieldtype that enables the pasting of expression engine code into the field',
//----------------------------------------
// Additional Key => Value pairs go here
// END
''=>''
);Thanks for any help
UPDATE
So I am still working at it and feel like I am getting closer, but I am still missing I feel key parts of the puzzle.
MCP:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Textarea_paster_mcp {
function __construct()
{
$this->EE =& get_instance();
}
function index()
{
$this->EE->load->library('javascript');
$this->EE->load->library('table');
$this->EE->load->helper('form');
$this->EE->cp->set_variable('cp_page_title', $this->EE->lang->line('textarea_paster_module_name'));
/* $vars = array();
if (empty($this->settings['htaccess_path']) || empty($this->settings['htaccess_template']))
{
$vars['need_settings'] = $this->EE->lang->line('need_settings');
}
else
{
$vars['need_settings'] = false;
$vars['link'] = "<a >".$this->EE->lang->line('generate')."</a>";
}*/
return $this->EE->load->view('index');
}
}
// END CLASS
/* End of file mcp.textarea_paster.php */
/* Location: ./system/expressionengine/third_party/modules/textarea_paster/mcp.textarea_paster.php */mod:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Textarea_paster
{
public $return_data = "";
public function __construct()
{
$this->EE =& get_instance();
$this->return_data = "Hello World";
}
}and I now have the beginnings of a fieldtype modification:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Textarea_paster_ft extends EE_Fieldtype {
var $info = array(
'name' => 'Textarea paster',
'version' => '0.1'
);
// --------------------------------------------------------------------
function display_field($data)
{
return form_input(array(
'name' => $this->field_name,
'id' => $this->field_id,
'value' => $data
));
}
}
// END textarea_paster_ft class
/* End of file ft.textarea_paster.php */
/* Location: ./system/expressionengine/third_party/textarea_paster/ft.textarea_paster.php */
