ThinkPHP5.0 模型更新操作
1、在取出數據後,更改字段內容後更新數據
$user = User::get(1); $user->name = ‘thinkphp‘; $user->email = ‘[email protected]‘; $user->save();
2、直接帶更新條件來更新數據
$user = new User; // save方法第二個參數為更新條件 $user->save([ ‘name‘ => ‘thinkphp‘, ‘email‘ => [email protected] ],[‘id‘ => 1]);
3、過濾非數據表字段的數據
$user = new User(); // 過濾post數組中的非數據表字段數據 $user->allowField(true)->save($_POST,[‘id‘ => 1]);
4、通過外部提交賦值給模型,並且希望指定某些字段寫入
$user = new User(); // post數組中只有name和email字段會寫入 $user->allowField([‘name‘,‘email‘])->save($_POST, [‘id‘ => 1]);
5、saveAll方法批量更新數據
$user = new User;$list = [ [‘id‘=>1, ‘name‘=>‘thinkphp‘, ‘email‘=>[email protected]], [‘id‘=>2, ‘name‘=>‘onethink‘, ‘email‘=>[email protected]] ]; $user->saveAll($list);
7、通過遍歷批量更新數據
$user = new User; $list = [ [‘id‘=>1, ‘name‘=>‘thinkphp‘, ‘email‘=>[email protected]
8、通過數據庫類更新數據(兩種形式)
$user = new User; $user->where(‘id‘, 1) ->update([‘name‘ => ‘thinkphp‘]); $user = new User; $user->update([‘id‘ => 1, ‘name‘ => ‘thinkphp‘]);
9、靜態方法直接更新數據(兩種形式)
//第一種形式 User::where(‘id‘, 1) ->update([‘name‘ => ‘thinkphp‘]); //第二種形式 User::update([‘id‘ => 1, ‘name‘ => ‘thinkphp‘]);
10、閉包函數使用更復雜的更新條件
$user = new User; $user->save([‘name‘ => ‘thinkphp‘],function($query){ // 更新status值為1 並且id大於10的數據 $query->where(‘status‘, 1)->where(‘id‘, ‘>‘, 10); });
11、自動識別主鍵更新
// 實例化模型 $user = new User; // 顯式指定更新數據操作 $user->isUpdate(true)->save([‘id‘ => 1, ‘name‘ => ‘thinkphp‘]);
