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

<?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

<?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 );
?>
