	public function ajax_page(){		//header('Content-Type:text/html;charset=gbk');		error_reporting(E_ALL);		$page = $this->input->post('pg');		$where = $this->input->post('action');		$array = explode('_',$where);		$condition['group_id'] = $array[0];		$condition['status'] = $array[1];		$condition['username'] = @iconv( "UTF-8","GBK", $array[2]);echo $condition['username'];		$condition['display'] = 15;		$condition['page'] = ($page-1) * 15;		$num = $this->member_model->Selcount($condition);        $url = base_url()."/index.php/admin/member_list/";		$this->page->select = $where;        $this->page_model->page($num,"15",$page,$url);        $data['page'] = $this->page->pagenav;		$data['user'] = $this->member_model->Selmember($condition);        $this->load->language('admin/member');        $data['lang'] = $this->lang->line('HtmlLanguages');  	 	//print_r($data['user']);//exit;   		$this->load->view('admin/member_list_ajax', $data);	}

<script type="text/javascript"> $(function(){    $('#begin_date').datepicker({dateFormat: 'yy-mm-dd'});    $('#end_date').datepicker({dateFormat: 'yy-mm-dd'});});function checkdata(){	if((!$('#begin_date').val()&&$('#end_date').val())||($('#begin_date').val()&&!$('#end_date').val())){		alert('<?=$lang['date_error']?>');		return false;	}}function php300(page,where){	var ajax_url = "/admin/ajax_page/";    where = encodeURIComponent(where);	$.ajax({		type: "POST",		url: ajax_url,		data:{ 			action: where,			pg: page		},		success: function(msg){			//alert(msg);			$("#ajax").html(msg);		},//$("#pager").html(msg);		error:function(){ 			$("#ajax").html("请求失败"); 		}    });   }</script>

回复讨论(解决方案)

ajax提交的：where = encodeURIComponent(where);
然后php：  $condition['username'] = @iconv( "UTF-8","GBK", $array[2]);
在线等待，求解决！

接收的参数用urldecode解码试试

你的客户端用的是 jquery 吧？
jq 的 ajax 是不需要自己做 url 编码的
既然你已经有 where = encodeURIComponent(where); 了
那么就需要自己再做一次 url 解码
$condition['username'] = iconv( "UTF-8","GBK",  uredecode($array[2]));

解决了！
用iconv 有时候失效了！ 用以下代码：


$a=urldecode("%E5%90%89%E6%9E%97");
$a=mb_convert_encoding($a, 'GB2312', 'UTF-8'); 
echo $a;
