Inserting Data w/ session data into database using Codeigniter - php

Question

Im having trouble in troubleshooting this problem, I want to save the searched data using input function and pass the id of it into the controller but im having a problem about it,
This is my Controller:
function add($id){
$this->point_m->addStudentSection($id);
redirect('admins_view/points/index');
}
This is my Model:
function addStudentSection($id){
$arr['section_id'] = $this->session->userdata('section_id');
$arr['dateadded'] = $this->input->post('dateadded');
$arr['schoolyear'] = $this->input->post('schoolyear');
$arr['semester'] = $this->input->post('semester');
$arr['point'] = $this->input->post('point');
$this->db->where('student_id',$id);
$this->db->insert('section_student',$arr);
}
in case that model above is wrong here's my other model function that i'am also using, also i am using sqlsrv for my database.
function addStudentSection($id){
$arr['section_id'] = $this->session->userdata('section_id');
$arr['dateadded'] = $this->input->post('dateadded');
$arr['schoolyear'] = $this->input->post('schoolyear');
$arr['semester'] = $this->input->post('semester');
$arr['point'] = $this->input->post('point');
$query = $this->db->query("
INSERT INTO [dbo].[section_student]
([student_id]
,[section_id]
,[dateadded]
,[schoolyear]
,[semester]
,[point])
VALUES
('$id'
,'$section_id'
,'$dateadded'
,'$schoolyear'
,'$semester'
,'$point')
");
}
so in this model i want to use also my section_id which is an session
This is my view :
<table class="table">
<tr>
<th>ID Number</th>
<th>Firstname</th>
<th>Middlename</th>
<th>Lastname</th>
<th>Total Points</th>
<th>Action</th>
</tr>
<?php
foreach ($pt as $p) {
?>
<tr>
<!-- echo query with join -->
<td><?php echo $p->idnumber ?></td>
<td><?php echo $p->firstname ?></td>
<td><?php echo $p->middlename ?></td>
<td><?php echo $p->lastname ?></td>
<td><?php echo $p->point ?></td>
<td>
Add
Redeem
</td>
</tr>
<?php
}
?>
</table>
In this table lies all the searched and retrieve datas from my display function as you can see the button to toggle is a modal.
this is my modal:
<!-- Modal -->
<form method="post" action="<?php echo base_url();?>admins/point/add">
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Add Point/s</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<label>Date</label>
<input type="date" name="dateadded" class="form-control">
<label>School year</label>
<select name="schoolyear" class="form-control">
<option value="2018-2019">2018-2019</option>
<option value="2019-2020">2019-2020</option>
</select>
<label>Semester</label>
<select name="semester" class="form-control">
<option value="1st">First Semester</option>
<option value="2nd">Second Semester</option>
<option value="summer">Summer</option>
</select>
<label>Points</label>
<input type="text" name="point" class="form-control">
</div>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Save changes</button>
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</form>
and this is the error response..
this is the error
Hope anyone from the community can help me,.

Answer 1

Because your controller add($id) expected 1 parameter, then in modal view you can't set form action like this:
<form method="post" action="<?php echo base_url();?>admins/point/add">
Change your form action to this:
<form method="post" action="<?php echo base_url();?>admins/point/add/$id">
Change $id with your parameter.
Here the docs.

Answer 2

you should add the id at the end of form action in your view.
or you can remove it from your function in controller and post it as a hidden input
so change your view to
<form method="post" action="<?php echo base_url();?>admins/point/add/$id">
or go to your controller and change it to
function add($id = null){
if($id == null){
$id = $this->input->post('id');
}
}
then ad a new hidden input to your view right before form close tag like this
<?php echo form_hidden('id',$the_id);?>
