how to check these 2 conditions.
iam us its controller code
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');
}
how solve it??

Answer 1

try this
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');
}
for compare result, you must use ==, not = (= assigning value, not checked the value)
I think you must change all "=" you have typed with "=="
I only give the idea
You can check the number of that teacher
$teacher_number = "SELECT COUNT(teacher) from teacher"
You can check the number of that attendance
$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
