Prevent inserting to database If total value is equal to 0,-CodePudding

When adding scores for students, I would like those with a total score of 0 not to be inserted into the database at all.

Controller:

  public function entrymarks()
 {
 $this->form_validation->set_error_delimiters('', '');
 $this->form_validation->set_rules('exam_group_class_batch_exam_subject_id', 'Subject', 'required|trim|xss_clean');

 if ($this->form_validation->run() == false) {
 $data = array(
 'exam_group_class_batch_exam_subject_id' => form_error('exam_group_class_batch_exam_subject_id'),
 );
 $array = array('status' => 0, 'error' => $data);
 echo json_encode($array);
 } else {

 $exam_group_student_id = $this->input->post('exam_group_student_id');

 $insert_array = array();
 $update_array = array();
 if (!empty($exam_group_student_id)) {
 foreach ($exam_group_student_id as $exam_group_student_key => $exam_group_student_value) {
 $attendance_post = $this->input->post('exam_group_student_attendance_' . $exam_group_student_value);
 if (isset($attendance_post)) {
 $attendance = $this->input->post('exam_group_student_attendance_' . $exam_group_student_value);
 } else {
 $attendance = "present";
 }


 $array = array(
 'exam_group_class_batch_exam_subject_id' => $this->input->post('exam_group_class_batch_exam_subject_id'),
 'exam_group_class_batch_exam_student_id' => $exam_group_student_value,
 'attendence' => $attendance,
 'get_ca1' => $this->input->post('exam_group_student_ca1_' . $exam_group_student_value),
 'get_ca2' => $this->input->post('exam_group_student_ca2_' . $exam_group_student_value),
 'get_ca3' => $this->input->post('exam_group_student_ca3_' . $exam_group_student_value),
 'get_ca4' => $this->input->post('exam_group_student_ca4_' . $exam_group_student_value),
 'get_exam' => $this->input->post('exam_group_student_exam_' . $exam_group_student_value),
 'note' => $this->input->post('exam_group_student_note_' . $exam_group_student_value),
 
 );
 $insert_array[] = $array;
 }
 }

 if ( intval($array['get_ca1']  $array['get_ca2'] $array['get_ca3'] $array['get_ca4'] $array['get_exam'] ) > 0 ) {
 $this->examgroupstudent_model->add_result($insert_array);
 }

 }
 $array = array('status' => '1', 'error' => '', 'message' => $this->lang->line('success_message'));
 echo json_encode($array);
 }
 }

I will like to first get the sum total of get_ca1 get_ca2 get_ca3 get_ca4 get_exam
then if it is 0, don't insert.

Please how do I do this?

CodePudding user response：

I don't think you can access the array value on the fly without any workaround, and you've placed the insert outside the foreach.

It would be best if you spent more time on these.

Code Indexing
Use proper IDE. Not like notepad.
Debug all and every line for errors.

Do like this.

Since you're not using batch insert, you can do it one by one.

$cal1 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
$cal2 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
$cal3 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
$cal4 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
$exam = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);

$total = $cal1   $cal2   $cal3   $cal4   $exam;

$array = array(
    'exam_group_class_batch_exam_subject_id' => $this->input->post('exam_group_class_batch_exam_subject_id'),
    'exam_group_class_batch_exam_student_id' => $exam_group_student_value,
    'attendence' => $attendance,
    'get_ca1' => $cal1,
    'get_ca2' => $cal2,
    'get_ca3' => $cal3,
    'get_ca4' => $cal4,
    'get_exam' => $exam,
    'note' => $this->input->post('exam_group_student_note_' . $exam_group_student_value)
);

if ($total > 0) {
    $this->examgroupstudent_model->add_result($array);
}

So final code will be

public function entrymarks()
{
    $this->form_validation->set_error_delimiters('', '');
    $this->form_validation->set_rules('exam_group_class_batch_exam_subject_id', 'Subject', 'required|trim|xss_clean');

    if ($this->form_validation->run() == false) {
        $data = array(
            'exam_group_class_batch_exam_subject_id' => form_error('exam_group_class_batch_exam_subject_id'),
        );
        $array = array('status' => 0, 'error' => $data);
        echo json_encode($array);
    } else {

        $exam_group_student_id = $this->input->post('exam_group_student_id');

        $insert_array = array();
        $update_array = array();
        if (!empty($exam_group_student_id)) {
            foreach ($exam_group_student_id as $exam_group_student_key => $exam_group_student_value) {
                $attendance_post = $this->input->post('exam_group_student_attendance_' . $exam_group_student_value);
                if (isset($attendance_post)) {
                    $attendance = $this->input->post('exam_group_student_attendance_' . $exam_group_student_value);
                } else {
                    $attendance = "present";
                }

                $cal1 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
                $cal2 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
                $cal3 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
                $cal4 = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);
                $exam = $this->input->post('exam_group_student_ca1_' . $exam_group_student_value);

                $total = $cal1   $cal2   $cal3   $cal4   $exam;

                $array = array(
                    'exam_group_class_batch_exam_subject_id' => $this->input->post('exam_group_class_batch_exam_subject_id'),
                    'exam_group_class_batch_exam_student_id' => $exam_group_student_value,
                    'attendence' => $attendance,
                    'get_ca1' => $cal1,
                    'get_ca2' => $cal2,
                    'get_ca3' => $cal3,
                    'get_ca4' => $cal4,
                    'get_exam' => $exam,
                    'note' => $this->input->post('exam_group_student_note_' . $exam_group_student_value)
                );

                if ($total > 0) {
                    $this->examgroupstudent_model->add_result($array);
                }
            }
        }
    }

    $array = array('status' => '1', 'error' => '', 'message' => $this->lang->line('success_message'));
    echo json_encode($array);
