php 中如何记住用户名和密码呢?

前台页面:

 前台html代码如下:

                        

                              
                              用户名:
							  
                                
                                                              
                              
                        
                         
              
密码:                            
                                 
                              
                          
                          
                            

                                
                                 
                                记住密码
                                
                                
                                 
                                自动登录
                                
                            
                            
                         
                            
                           

                              

                                
 验证码:
                                
 
                                
                                

                                
                            
                             
                           
                         
                        

 

提交之后,在后台进行如下处理

接收前台提交的参数:

	$user=trim($_POST["user"]);
        $old_password=trim($_POST["password"]);

 如果记住用户名,则保存用户到cookie中:

 $cookie_timeout=time()+3600*24*365;
            if(!empty($_POST["remember_pass"]))
            {
                setcookie("username", $user,$cookie_timeout );
                setcookie("password", $old_password, $cookie_timeout);
                setcookie("remember_pass", true, $cookie_timeout);
//                echo "记住我";
            }else{
//                echo "不记住";
                setcookie("username", null, $cookie_timeout);
                setcookie("password", null, $cookie_timeout);
                setcookie("remember_pass", null, $cookie_timeout);
            }
            if(!empty($_POST["auto_login"]))
            {
                setcookie("auto_login", true, $cookie_timeout);
            }else{
                setcookie("auto_login", null, $cookie_timeout);
            }

 

下次登录时,先从cookie获取用户和密码:

 //获取cookie
            var username="";
            var password="";
            var remember_pass="";
            var auto_login="";
            if(com.whuang.hsj.isHasValue(remember_pass) && remember_pass==1){//是否记住密码
                if(com.whuang.hsj.isHasValue(username)){//cookie中的用户名不为空
                    var usernameObj=com.whuang.hsj.$$one('user');
                    usernameObj.value=username;
                }
                if(com.whuang.hsj.isHasValue(password)){//cookie中的密码不为空
                    var passwordObj=com.whuang.hsj.$$one('password');
                    passwordObj.value=password;
                }
                $('div input[name=remember_pass]').attr("checked",'true');
            }else{
                $('div input[name=remember_pass]').attr("checked",null);
            }
            if(com.whuang.hsj.isHasValue(auto_login) && auto_login==1){//是否自动登录
                $('div input[name=remember_pass]').attr("checked",'true');
                $('div input[name=auto_login]').attr("checked",'true');
//                document.forms[0].submit();
                timingLogin=setTimeout(function(){document.forms[0].submit();},2000);//1秒钟之后自动登录
            }

 依赖的js方法:

 var dealAutoSubmit=function(this22){
            var isChecked=com.whuang.hsj.isCheckcheckbox(this22);
            // console.log(isChecked);
            if(isChecked){
                if(!com.whuang.hsj.isCheckcheckbox("remember_pass")){
                    com.whuang.hsj.setCheckedCheckboxOne("remember_pass");
                }

            }
        }
/******************************
 * select the single checkbox
 */
com.whuang.hsj.setCheckedCheckboxOne = function(checkbox2233) {
	if (typeof checkbox2233 == 'string') {
		checkbox2233 = com.whuang.hsj.$$one(checkbox2233);
		if(checkbox2233==null ||checkbox2233==undefined){
			checkbox2233=com.whuang.hsj.$$id(checkbox2233);
		}
	}
	checkbox2233.checked = true;
};

/***
 * if is radio ,please use com.whuang.hsj.$$arr
 * @param name22
 * @returns
 */
com.whuang.hsj.$$one = function(name22) {
	if (com.whuang.hsj.isHasValue(name22)) {
		var names222=document.getElementsByName(name22);
		//alert("names222:"+names222);
		//alert("typeof:"+(typeof names222 ));
		var className=Object.prototype.toString.call(names222);
		var boolean_isArray;
		var ieHtmlCollection='[object HTMLCollection]';
		if(isIEtest)//if browser is IE
		{
                 boolean_isArray=( className=== '[object Object]') ||(className=== ieHtmlCollection) ||names222 instanceof Array ;
		}else
		{
                 boolean_isArray=( className=== '[object Array]') ||(className=== '[object NodeList]'  )||(className==ieHtmlCollection)||names222 instanceof Array||names222 instanceof NodeList;
		}
		if(names222){
             if(boolean_isArray){
                     return names222[0];
             }else{
                     return names222;//why add [0] ??
			}
		}else{
			return "";
		}
	} else {
		return "";
	}
};

 

说明:

com.whuang.hsj.isHasValue 是js方法,用于判断是否有值

 

php中判断是否是移动端访问网页

是否是手机

function is_mobile()
{
	$user_agent = $_SERVER['HTTP_USER_AGENT'];
	$mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte");
	$is_mobile = false;
	foreach ($mobile_agents as $device) {
		if (stristr($user_agent, $device)) {
			$is_mobile = true;
			break;
		}
	}
	return $is_mobile;
}
