CI框架中集成CKEditor编辑器的教程

1、将fckeditor目录置入CI_PATH/system/plugins/

2、在CI_PATH/system/application/config/config.php中加入：

$config['fckeditor_basepath'] = "/system/plugins/fckeditor/";
$config['fckeditor_toolbarset_default'] = 'Default';

3、创建helper，在/system/application/helpers新建form_helper.php

代码如下:
<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
include_once( BASEPATH . '/helpers/form_helper'.EXT);
function form_fckeditor($data = '', $value = '', $extra = '')
{
     $CI =& get_instance();
    $fckeditor_basepath = $CI->config->item('fckeditor_basepath');
     require_once( $_SERVER["DOCUMENT_ROOT"] . $fckeditor_basepath. 'fckeditor.php' );
    $instanceName = ( is_array($data) && isset($data['name'])   ) ? $data['name'] : $data;
    $fckeditor = new FCKeditor($instanceName);
     if( $fckeditor->IsCompatible() )
    {
         $fckeditor->Value = html_entity_decode($value);
        $fckeditor->BasePath = $fckeditor_basepath;
         if( $fckeditor_toolbarset = $CI->config->item('fckeditor_toolbarset_default'))
                $fckeditor->ToolbarSet = $fckeditor_toolbarset;
         if( is_array($data) )
        {
            if( isset($data['value']) )
                $fckeditor->Value = html_entity_decode($data['value']);
             if( isset($data['basepath']) )
                $fckeditor->BasePath = $data['basepath'];
             if( isset($data['toolbarset']) )
                $fckeditor->ToolbarSet = $data['toolbarset'];
             if( isset($data['width']) )
                $fckeditor->Width = $data['width'];
             if( isset($data['height']) )
                $fckeditor->Height = $data['height'];
        }
        return $fckeditor->CreateHtml();
    }
    else
    {
        return form_textarea( $data, $value, $extra );
    }
}
?>

4、在项目中使用fckeditor

代码如下:
<?php
$this->load->helper('form_helper');
$data = array(
    'name'        => 'newsContent',
    'id'          => 'newsContent',
    //'toolbarset'  => 'Advanced',
    'basepath'    => $this->config->item('fckeditor_basepath'),
    'width'       => '80%',
    'height'      => '200'
);
echo form_fckeditor( $data );
?>
