整理文檔,搜刮出一個php 實現收藏功能的示例代碼,稍微整理精簡一下做下分享.PHP應用
HTML:PHP應用
<a class = "x" id="{$photo.id}" uid="{$Think.session.uid}" status = "{$collect_pic}" href = "void(0);">
<if condition = "$collect_num gt 0">
<span>取消收藏</span>
<else/><span>收藏</span></if></a>
Js:PHP應用
//點擊收藏,實現已收藏
$('.x').on('click',function(){
var Oa=$(this);
var id=Oa.attr('id');//獲取圖片id屬性
var uid = Oa.attr('uid');//獲取用戶id
var status = Oa.attr('status'); //獲取收藏狀態 1收藏,0取消收藏
$.post('url',{id:id,uid:uid,status:status},function(msg){
if(msg.status==1){
Oa.find("span").text('取消收藏');
Oa.attr('status','1');
}else{
Oa.find("span").text('收藏');
Oa.attr('status','0');
}
},'json')
})
PHP:PHP應用
//判斷用戶是否已收藏該圖片
$data['uid'] = $_SESSION['uid'];
$data['pid'] = $pid;
$collect_pic = M('collect')->where($data)->getfield('status');
$this->collect_num = $collect_num;
$this->collect_pic = $collect_pic;
//收藏成功
public function cang(){
$data['pid'] = isset($_POST['id'])?intval(trim($_POST['id'])):0;
$data['uid'] = $_SESSION['uid'];
//默認o收藏 1取消收藏
$status = isset($_POST['status'])?intval(trim($_POST['status'])):0;
$db = M('collect');
if($status == 0){
//數據組裝,忽略
if(M('collect')->data($collect)->add()){
$msg['info'] = "ok";
$msg['status'] = 1;
$this->ajaxreturn($msg);
exit;
}else{
$msg['info'] = 'fail';
$msg['status'] = 1;
$this->ajaxreturn($msg);
}
}else{
//取消收藏
if($db->where($data)->delete()){
$msg['info'] = "ok";
$msg['status'] = 0;
$this->ajaxreturn($msg);
exit;
}else{
$msg['info'] = 'fail';
$msg['status'] = 0;
$this->ajaxreturn($msg);
}
}
思路：基本沒什么難度,注意細節即可.PHP應用
