How to insert an array in database in Codeigniter? - php

Question

I have a problem in inserting array in the database in Codeigniter, I tried following way but it gives an error "Message: Illegal string offset 'year'", "Message: Illegal string offset 'month'" and so on..., I really confused about how to solve this, please help.
this is the form:
<form action="<?php echo base_url();?>hr/Home/store_attendance" method="post"
id="student_attendance_entry">
<input type="hidden" name="year" value="<?php echo $year; ?>" />
<input type="hidden" name="month" value="<?php echo $month; ?>" />
<?php foreach($staffs as $staff): ?>
<table class="table table-striped table-bordered table-hover attendance_entry"
style="border:initial;border: 1px solid #ddd;" id="sample_editable_2">
<thead>
<tr>
<th style="width: 50px !important;">شماره</th>
<th align="center" style="width:auto%">آی دی</th>
<th align="center" style="width:15%">نام</th>
<th align="center" style="width:15%;"> ولد</th>
<th align="center" style="width:auto">حاضر</th>
<th align="center" style="width:auto">غیر حاضر</th>
<th align="center" style="width:auto">توضیحات</th>
</tr>
</thead>
<tbody>
<?php $a=1; foreach($staffs as $st):?>
<tr>
<td align="center" style="font-size: 11px"><?php echo $a;?></td>
<td align="center" style="font-size: 11px"><?php echo $st['s_id'];?></td>
<td align="center"><?php echo $st['dari_name'];?></td>
<td align="center"><?php echo $st['dari_fName'];?></td>
<td>
<input type="number" min="0" class="form-control" name="total_present_day[]"
value="<?php if($st['total_present']==null){echo '';}else{ echo $st['total_present'];}?>"
data="<?php echo $a;?>">
<input type="hidden" name="salary_type[]" id="salary_type" value="<?php echo $st['salary_type']?>">
</td>
<td>
<input type="number" min="0" class="form-control" name="total_absent_day[]"
value="<?php if($st['absent']==null){echo '';}else{ echo $st['absent'];}?>"
data="<?php echo $a;?>">
<input type="hidden" class="form-control" name="staff_id[]" value="<?php echo $st['s_id'];?>">
</td>
<td>
<textarea min="0" class="form-control" name="memo[]"
colspan='3' rowspan="1"
data="<?php echo $a;?>"><?php if($st['memo']==null){echo '';}else{ echo $st['memo'];}?></textarea>
</td>
</tr>
<?php $a++;endforeach;?>
</tbody>
</table>
<?php endforeach; ?>
<br>
<div class="form-actions right">
<a href="<?php echo base_url();?>student/school/attendance" class="btn default" data-dismiss="modal"><i
class="fa fa-close"></i> بستن</a>
<input type="submit" name="save" class="btn blue" value="ذخیره" />
</div>
this is the controller:
public function store_attendance()
{
$data=array(
'year' => $this->input->post('year'),
'month' => $this->input->post('month'),
'staff_id' => $this->input->post('staff_id'),
'total_present_day' => $this->input->post('total_present_day'),
'total_absent_day'=>$this->input->post('total_absent_day'),
'salary_type'=>$this->input->post('salary_type'),
'memo'=>$this->input->post('memo')
);
$this->dd($data);
// $this->dd($class);
$insert_att = $this->stuff_model->add_staff_attendance($data);
// var_dump($insert_att);
if($insert_att)
{
echo redirect(base_url().'hr/register_employee_attendance');
}
}
this is the model:
public function add_staff_attendance($data)
{
$this->db->trans_begin();
foreach ($data['total_present_day'] as $key => $value) {
{
$dataToSave = array(
'year' => $value['year'],
'month' => $value['month'],
'type_id'=>$value['salary_type'][$key],
'total_present' => $value['total_present_day'][$key],
'absent'=>$value['total_absent_day'][$key],
'memo'=>$value['memo'][$key],
'staf_id' => $value['staff_id'][$key]
);
$this->db->insert('staff_attendance', $dataToSave);
}
if ($this->db->trans_status() === false) {
$this->db->trans_rollback();
return false;
} else {
$this->db->trans_commit();
return true;
}
}
}
I called $this->dd($data) in controller and this is the output:
array (
'Total' => 7,
)
array (
'year' => '1400',
'month' => '2',
'staff_id' =>
array (
0 => '3',
),
'total_present_day' =>
array (
0 => '26',
),
'total_absent_day' =>
array (
0 => '0',
),
'salary_type' => '1',
'memo' =>
array (
0 => 'dds',
),
)
And this is the result of echo '<pre>'; print_r($data); echo '</pre>'; In model:
Array
(
[year] => 1400
[month] => 1
[staff_id] => Array
(
[0] => 3
[1] => 1
)
[total_present_day] => Array
(
[0] => 26
[1] => 20
)
[total_absent_day] => Array
(
[0] => 0
[1] => 6
)
[salary_type] => Array
(
[0] => 1
[1] => 1
)
[memo] => Array
(
[0] => asfd
[1] => saef
)
)
Array
(
[year] => 1400
[month] => 1
[staff_id] => Array
(
[0] => 3
[1] => 1
)
[total_present_day] => Array
(
[0] => 26
[1] => 20
)
[total_absent_day] => Array
(
[0] => 0
[1] => 6
)
[salary_type] => Array
(
[0] => 1
[1] => 1
)
[memo] => Array
(
[0] => asfd
[1] => saef
)
)

Your submitted data is structured in a logical, minimalistic, yet irregular fashion. By reconfiguring the name attributes of the form fields in your view, you can largely reduce the lines of processing code in the controller and the model.
Move the hidden fields inside your foeach() loop and declare dynamic indexes. Effectively the named fields would resemble this:
<?php foreach($staffs as $index => $staff) { ?>
<input type="hidden" name="attendance[<?php echo $index; ?>]['year']">
<input type="hidden" name="attendance[<?php echo $index; ?>]['month']">
<input type="number" name="attendance[<?php echo $index; ?>]['total_present']">
<input type="hidden" name="attendance[<?php echo $index; ?>]['type_id']">
<input type="number" name="attendance[<?php echo $index; ?>]['absent']">
<input type="hidden" name="attendance[<?php echo $index; ?>]['staf_id']">
<textarea name="attendance[<?php echo $index; ?>]['memo']"></textarea>
<?php } ?>
The controller needs a validation/sanitization process and some restucturing before blindly passing data to the model. I will not go into the validation/sanitization, but you should iterate the data, and deny it from being saved if ANY of the values are inappropriate.
Controller:
public function store_attendance(): void
{
// Definitely validate and sanitize the rows of data before passing to model.
// This shortcut is for demonstrating how to batch insert
if ($this->stuff_model->add_staff_attendance($this->input->post('attendance'))) {
redirect(base_url() . 'hr/home/register_employee_attendance');
} else {
// reload view and explain what went wrong
}
}
Model:
public function add_staff_attendance(array $data): bool
{
return $this->db->insert_batch('staff_attendance', $data);
}
None of this answer was tested.
To leave the hidden fields outside of the loop, you will need to assemble the rows' values into the correct structure before sending to the model for batch_insertion.
$presentDays = $this->input->post('total_present_day');
if ($presentDay) {
$rows = [];
foreach ($presentDays as $i => $presentDay) {
$rows[] = [
'year' => $this->input->post('year'),
'month' => $this->input->post('month'),
'staf_id' => $this->input->post('staff_id')[$i],
'total_present' => $this->input->post('total_present_day')[$i],
'absent' => $this->input->post('total_absent_day')[$i],
'type_id' => $this->input->post('salary_type')[$i],
'memo' => $this->input->post('memo')[$i]
];
}
if ($this->stuff_model->add_staff_attendance($rows)) {
redirect(base_url() . 'hr/home/register_employee_attendance');
} else {
// reload view and explain what went wrong
}
}

public function add_staff_attendance($data)
{
$this->db->trans_begin();
foreach ($data['total_present_day'] as $key => $value) {
{
$dataToSave = array(
'year' => $data['year'], // this seems to be same for all
'month' => $data['month'], // this seems to be same for all
'type_id' => $value['salary_type'][$key], // please change name='salary_type[]' in your form
'total_present' => $value['total_present_day'][$key], // seems to be an array
'absent' => $value['total_absent_day'][$key], // seems to be an array
'memo' => $value['memo'][$key], // seems to be an array
'staf_id' => $value['staff_id'][$key] // seems to be an array
);
$this->db->insert('staff_attendance', $dataToSave);
}
if ($this->db->trans_status() === false) {
$this->db->trans_rollback();
return false;
} else {
$this->db->trans_commit();
return true;
}
}
}

I solved my problem by changing some codes in the controller and model.
controller:
public function store_attendance()
{
$data = array();
$insert_att = 0;
$tst = $this->input->post('total_present_day');
for ($i=0; $i < count($tst); $i++) {
$data = array(
'year' => $this->input->post('year'),
'month' => $this->input->post('month'),
'staf_id' => $this->input->post('staff_id')[$i],
'total_present' => $this->input->post('total_present_day')[$i],
'absent'=>$this->input->post('total_absent_day')[$i],
'type_id'=>$this->input->post('salary_type')[$i],
'memo'=>$this->input->post('memo')[$i],
);
// var_dump($data);
$this->get_public_data->saveData('staff_attendance', $data);
}
echo redirect(base_url().'hr/home/rgisterAttendance');
}
Model:
public function add_staff_attendance($data)
{
$this->db->insert('staff_attendance', $data);
}

Answer 4

it seems that the error is in the controller, you must go through the array while it is saving.
public function store_attendance()
{
$data=array(
'year' => $this->input->post('year'),
'month' => $this->input->post('month'),
'staff_id' => $this->input->post('staff_id'),
'total_present_day' => $this->input->post('total_present_day'),
'total_absent_day'=>$this->input->post('total_absent_day'),
'salary_type'=>$this->input->post('salary_type'),
'memo'=>$this->input->post('memo')
);
foreach($data as $d):
$insert_att = $this->stuff_model->add_staff_attendance($d);
if($insert_att)
{
echo redirect(base_url().'hr/register_employee_attendance');
}
else
{
echo redirect(base_url().'hr/register_employee_attendance');
}
endforeach;
}
You should try something like it
