CKEditor是在很多开发过程中都会用到的一个富文本编辑器，那么如何在CI框架中使用它呢？这里介绍了在CI下使用CKEditor的方法，版本比较低，是在CI 1.7.3下使用fckeditor 2.6.6。供大家参考。
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 );
?>
