PHP',cache: false,data: 'id=1',dataType: 'json',error: function(){
alert('出错了!');
},success: function(json){
if(json){
$.each(json,function(index,array){
var str = "
"+array['mood_val']+""+array['mood_name']+"
";
$("#mood ul").append(str);
});
}
}
});
返回就添加到网页里,然后就点击表情逻辑,也ajax到后台
0){
face.prev().css("height",data+"px");
face.parent().find("span").html(val);
face.find("img").addClass("selected");
}else{
alert(data);
}
});
});
这样整个前台就完成了工作
首先要导入sql.PHP数据库文件
PHP;">
include_once("
sql.
PHP");
这个文件处理的是整个功能的核心,处理数据库,cookies...
1.处理获取投票人数代码
PHP;">
$mname = explode(',',$moodname);//心情说明
$num = count($mname);
$mpic = explode(',$moodpic);//心情图标
$id = (int)$_GET['id'];
$query =
MysqL_query("select * from mood where id=$id");
$rs =
MysqL_fetch_array($query);
if($rs){
$total = $rs['mood0']+$rs['mood1']+$rs['mood2']+$rs['mood3']+$rs['mood4'];
for($i=0;$i<$num;$i++){
$field = 'mood'.$i;
$m_val = intval($rs[$field]);
$height = 0; //柱图高度
if($total && $m_val){
$height=round(($m_val/$total)*$moodpicheight); //计算高度
}
$arr[] = array(
'mid' => $i,'mood_name' => $mname[$i],'mood_pic' => $mpic[$i],'mood_val' => $m_val,'height' => $height
);
}
echo json_encode($arr);
} else {
for($i=0;$i<$num;$i++){
$arr[] = array(
'mid' => $i,'mood_val' => 0,'height' => 0
);
}
echo json_encode($arr);
}
2.处理投票功能
PHP;">
$id = (int)$_POST['id'];
$mid = (int)$_POST['moodid'];
if($mid<0 || !$id){
echo "
错误";
exit;
}
$havemood = chk_mood($id);
if($havemood==1){
echo "您已表达过了";exit;
}
$field = 'mood'.$mid;
//查询是否有这个id
$result = MysqL_query("select 1 from mood where id='{$id}'");
$row = MysqL_fetch_array($result);
if(is_array($row)){
$query = MysqL_query("update mood set ".$field."=".$field."+1 where id=".$id);
if($query){
setcookie("mood".$id,$mid.$id,time()+3600);
$query2 = MysqL_query("select from mood where id=$id");
$rs = MysqL_fetch_array($query2);
$total = $rs['mood0']+$rs['mood1']+$rs['mood2']+$rs['mood3']+$rs['mood4'];
$height = round(($rs[$field]/$total)$moodpicheight);
echo $height;
}else{
echo -1;
}
} else {
MysqL_query("INSERT INTO mood(id,mood0,mood1,mood2,mood3,mood4)VALUES ('{$id}','0','0')");
$query = MysqL_query("update mood set ".$field."=".$field."+1 where id=".$id);
setcookie("mood".$id,time()+3600);
echo $moodpicheight;
}
这个文件很简单,基本都是在处理数据库,逻辑也不是很复杂。可以自己下来细心看。
一个通用的数据库信息储存文件,数据库的ip、帐号、密码、数据库名等等
PHP;">
$host="localhost";
$db_user="root";
$db_pass="";
$db_name="demo";
$timezone="Asia/Shanghai";
$link=MysqL_connect($host,$db_user,$db_pass);
MysqL_select_db($db_name,$link);
MysqL_query("SET names UTF8");
header("Content-Type: text/html; charset=utf-8");
到目前所有的核心代码都也贴出,大神就跳过,如果有需要就下载来看一看
对了,还有一个数据库,行吧DDL也贴出来
sql;">
CREATE TABLE `mood` (
`id` tinyint(5) NOT NULL,`mood0` int(9) unsigned NOT NULL,`mood1` int(9) unsigned NOT NULL,`mood2` int(9) unsigned NOT NULL,`mood3` int(9) unsigned NOT NULL,`mood4` int(9) unsigned NOT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
