Question

我有一个数据库表WysTeacherattendance -table字段是（id t_adate t_amonth t_ayear t_attendance）

id  t_adate t_amonth t_ayear t_attendance   

1    15       07     2015       1   
2    15       07      2015      1   
3    15       07      2015      1

10   15       07      2015      1

我有10名教师，iam输入所有考勤人数为1，插入数据库t_attendance为1，所有10行。

当我输入提交按钮值进入数据库并重定向到另一个页面时，在检查所有t_attendance是否为1之前。

第一个条件

如果全部1转到主页。

id  t_adate t_amonth t_ayear t_attendance   

1    15       07     2015       1   
2    15       07      2015      1   
3    15       07      2015      1       
4    15       07      2015      0           
5    15       07      2015      1       
6    15       07      2015      1       
7    15       07      2015      0           
8    15       07      2015      1       
9    15       07      2015      1       
10   15       07      2015      1

第二个条件

如果任何t_attendance值为0，请转到考勤页面。

如何检查这两个条件。

告诉我们它的控制器代码

foreach ($teachers as $teacher){
                        $teacheratt = new WysTeacherattendance();
                        $teacheratt->t_auserid = $teacher->user_id;
                        $teacheratt->t_adate=$date_exploded[0];
                        $teacheratt->t_amonth=$date_exploded[1];
                        $teacheratt->t_ayear=$date_exploded[2];
                        $teacheratt->t_attendance=Input::get($teacher->user_id);
                        $teacheratt ->save();
                    } 
                    if($users = DB::table('wys_teacherattendances')
                           ->where('t_adate',$date_exploded[0])
                          ->whereIn('t_attendance', array(1))->get())
                     {return Redirect::route('GetTeachersearchAttendence')
                        ->with('success',' teacher exist');  
                     }
                     if($users = DB::table('wys_teacherattendances')
                           ->where('t_adate',$date_exploded[0])
                          ->where('t_attendance', '=',0)->get())
                     {return Redirect::route('AddTeacherabsentReason',$date_exploded[0])
                       ->with('success',' teacher exist');  
                    }         
                }`

but only work this condition `if($users = DB::table('wys_teacherattendances')
                           ->where('t_adate',$date_exploded[0])
                          ->whereIn('t_attendance', array(1))->get())
                     {return Redirect::route('GetTeachersearchAttendence')
                        ->with('success',' teacher exist');  
                     }

如何解决？

Answer 1

试试这个

if($users == DB::table('wys_teacherattendances')
    ->where('t_adate',$date_exploded[0])
    ->whereIn('t_attendance', array(1))->get())
{return Redirect::route('GetTeachersearchAttendence')
    ->with('success',' teacher exist');  
}

对于比较结果，您必须使用==，而不是=（=赋值，不检查值）

我认为你必须改变所有＆＃34; =＆＃34;您输入了＆＃34; ==＆＃34;

我只是提出这个想法您可以查看该教师的人数

$teacher_number = "SELECT COUNT(teacher) from teacher"

您可以查看出席人数

$attendance = "SELECT COUNT(attendance) from attendance where 
attendance = 1 and date = yourdate"

if $teacher_number == $attendance
    redirect home.page
else if $teacher_number > $attendance
    redirect attendance.page
