《PHP學(xué)習(xí)：php 實(shí)現(xiàn)收藏功能的示例代碼》要點(diǎn)：
本文介紹了PHP學(xué)習(xí)：php 實(shí)現(xiàn)收藏功能的示例代碼，希望對(duì)您有用。如果有疑問(wèn)，可以聯(lián)系我們。
整理文檔,搜刮出一個(gè)php 實(shí)現(xiàn)收藏功能的示例代碼,稍微整理精簡(jiǎn)一下做下分享.PHP應(yīng)用
HTML:PHP應(yīng)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(yīng)用
//點(diǎn)擊收藏,實(shí)現(xiàn)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(tài) 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(yīng)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(rèn)o收藏 1取消收藏
$status = isset($_POST['status'])?intval(trim($_POST['status'])):0;
$db = M('collect');
if($status == 0){
//數(shù)據(jù)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(méi)什么難度,注意細(xì)節(jié)即可.PHP應(yīng)用
以上就是本文的全部?jī)?nèi)容,希望對(duì)大家的學(xué)習(xí)有所幫助,也希望大家多多支持腳本之家.PHP應(yīng)用
