thinkphp基础编程入门知识汇总

1、配置项目

在conf目录下面的config.php是配置文件，可以用来配置数据库信息。

return array(
//'配置项'=>'配置值'
'DB_TYPE'=>'mysql',
'DB_HOST'=>'localhost',
'DB_NAME'=>'haqiu',
'DB_USER'=>'root',
'DB_PWD'=>'',
'DB_PREFIX'=>'blog_',
//'DEFAULT_THEME'=>'default',

);
?>

2、模板定义
 
 

3、模型定义

class loginModel extends Model{
protected $_validate = array(
 array('username','checkname','用户名不能为空！',0,'callback',1),
 array('username','','该账号已存在！',0,'unique',1),
 array('password','checkpwd','密码至少六位！',0,'callback'),
 array('repassword','password','确认密码不正确！',1,'confirm'),
 array('email','checkemail','邮箱格式不正确！',0,'callback'),
 );

public function checkname(){
 $name =$_POST["username"];
 if ($name==null){
  returnfalse;
 }
 else {
  returntrue;
 }
}

public function checkpwd(){
 $pwdlen =strlen($_POST["password"]);
 if($pwdlen<6){
  returnfalse;
 }
 else {
  returntrue;
 }
}

public function checkemail(){
 $email = $_POST["email"];
 $a =substr_count($email,'@');
 
 if ($a==1){
  returntrue;
 }
 else {
  returnfalse;
 }
}

protected $_auto = array(
 array('password','md5',1,'function'),
);
  
}
?>

4、逻辑

在项目的LibAction目录下自动生成的IndexAction.class.php文件，这个文件就是控制器，完成Index的模块实现。删除IndexAction类默认生成的Index方法，添加新的方法：

// 本类由系统自动生成，仅供测试用途
class IndexAction extends Action{

public function zhuce(){
 $this->display();
}

public function insertUser(){
 $user=D("login");
 $vo =$user->create();
 if($vo != false){
 $user->add();
 $this->redirect('login');
 }else{
  echo$user->getError();
 }
}
   publicfunction login(){
    $this->display();
   }

public function userlogin(){
  $user=M("login");
  //echo$_POST["username"];
  //
  $vo =$user->create();
  $condition["username"] =$vo['username'];
  //echo$condition["username"];
 //var_dump($vo);
 //exit;
  $usercheck =$user->where($condition)->findAll();
  //var_dump ($usercheck);
 // echo $usercheck[0]["password"];
 //$usercheck =$user->getByName($vo['username']);
 //var_dump ( $usercheck);
  if ($usercheck==null){
   echo"用户名不存在";
  }
  elseif($usercheck[0]["password"]!=md5($vo["password"])){
   echo "密码输入错误！";
   }
   else {
  setcookie('user_id',$usercheck[0]["id"],time()+3600);
  $this->redirect('edit');
   }

}

public function edit(){
 //var_dump($_COOKIE["user_id"]);
 $this->display();
}

public function insertblog(){
$diary=D("diary");
$vo=$diary->create();
if($vo != false){
 $diary->add();
 $this->redirect('show');
 }else{
  echo$diary->getError();
 }
}

   publicfunction show(){
 $diary = D("diary");
 $board = D("board");

   $condition["userID"] = $_COOKIE["user_id"];
      $list =$diary->where($condition)->order('iddesc')->find();
 //setcookie("diaryID",$list[0]["id"],time()+3600);
 $_SESSION["diaryID"]=$list["id"];
 echo"主题：".$list["title"]."    时间：".$list["datetime"].'
';
 echo"内容：".$list["content"].'
';
      echo"***********************************************
";

 //var_dump($_SESSION["diaryID"]);
 $conditionBoard["diaryID"] =$_SESSION["diaryID"];
 $boardlist =$board->where($conditionBoard)->order('iddesc')->findAll();
 foreach ($boardlist as$value){
  echo$value["username"]."    ".$value["creat_time"].'
';
  echo$value["content"].'
';
  echo"____________________________________________
";
 }
 
 $this->display();
}

public function boardinsert(){
 $board = D("board");
 $vo =$board->create();
 if($vo != false){
  $board->add();
  echo"评论成功！";
  $this->redirect('show');
 }
 else{
  echo$diary->getError();
 }
}
}
?>
