How to store values of the index in an array? - php

Question

I have an array that looks like this
Array ( [0] => test1 [1] => test4 [2] => test2 )
I got this value from my database using Codeigniter built-in function
And whenever I try to insert this value back in my database, it's inserting the index instead of the value itself
The error I'm getting is
As you can see, instead of storing test1, test4, test2 in the fields under username, it is storing the index which are 0, 1, 2.
How to fix this please?

Answer 1

why you use $data['users'] in controller. Where $users contains index value. You try this
//CONTROLLER
$data = $this->admin_model->getUsers($last_id); //last id is the latest id.
//VIEW
foreach ($data as $row) {
$user[] = $row->username;
}

Answer 2

Boy these are too many comments for a small problem.
First of all #blakcat7, I hope you won't mind If I suggest a little change in your DB Schema. Use indexes and proper normalization it always helps. I have simulated your case on my machine.
It is your user table, I have added an ID with in this table.
Its your project table, just changed some field names, you can use your own
This is your table to create your join, Although you could have used user_id or posted_by field in projects table which could solve your problem too
Now Where i see it, you have users in your database table, you also have added projects but now you want to assign or associate that project with the user.
Make it simple just create a view where you can see both projects and users
Rendered by the Controller function
public function assignProject()
{
$data['projects']=$this->admin_model->getAll('projects');
$data['users']=$this->admin_model->getAll('user');
if($_POST)
{
$this->admin_model->assignUser($_POST);
$data['success']='User Assigned';
$this->load->view('assignProjects',$data);
}
else
{
$this->load->view('assignProjects',$data);
}
}
The view rendered by following markup
<form action="" method="post">
<div class="form-group">
<label>Project</label>
<select name="project" class="form-control">
<?php for($i=0;$i<count($projects);$i++){?>
<option value="<?php echo $projects[$i]['id']?>"><?php echo $projects[$i]['title']?></option>
<?php }?>
</select>
</div>
<div class="form-group">
<label>Users</label>
<select name="user" class="form-control">
<?php for($i=0;$i<count($users);$i++){?>
<option value="<?php echo $users[$i]['id']?>"><?php echo $users[$i]['username']?></option>
<?php }?>
</select>
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary">Assing User</button>
</div>
</form>
Just hit Assign User and the following function in the Model will save it in the project-user table
public function assignUser($data)
{
$record=array(
'user_id'=>$data['user'],
'project_id'=>$data['project'],
);
$this->db->insert('user_projects',$record);
}
Remember, always use an Index (ID) field in your tables, would make your DB iteration life simpler

OKAY EVERYONE, THANKS Y'ALL FOR YOUR HELP. IT REALLY MEANS SO MUCH TO ME. AFTER LIKE 2 DAYS OF STRUGGLE I FINALLY FIXED MY PROBLEM. ^_^
Special thanks to Michael K for helping me point out the problem and Malik Mudassar for giving me the idea how to do it.
Controller
public function add_recommended() {
$lid = $this->admin_model->getID();
foreach ($lid as $id) {
$last_id = $id['projectID'];
}
$data['users'] = $this->admin_model->getUsers($last_id);
$this->load->view('admin/projects/rec-employee', $data);
if ($_POST) {
$users = $this->input->post('recommended');
foreach ($users as $user):
$data = array(
'projectID' => $last_id,
'userID' => $user
);
$id = $this->admin_model->insertRecEmp($data);
endforeach;
$this->session->set_flashdata('msg', '<div class="alert alert-success" role="alert">Success! New Project has been added.</div>');
redirect('admin/add_project');
}
}
Model
public function getUsers($id) {
$this->db->select('*');
$this->db->from('users_skills e');
$this->db->join('projects_skills p', 'e.skillsID = p.skillsID');
$this->db->join('users u', 'u.userID = e.userID');
$this->db->where('p.projectID', $id);
$this->db->group_by('e.userID');
$this->db->order_by('e.percentage', 'desc');
$query = $this->db->get();
if ($query->num_rows() > 0) {
foreach ($query->result() as $row) {
$result[] = $row;
}
return $result;
}
return false;
}
public function getID() {
$this->db->select_max('projectID');
$this->db->from('projects');
$query = $this->db->get();
$result = $query->result_array();
return $result;
}
public function insertRecEmp() {
$this->db->insert('projects_users', $data);
}
View
<form action="add_recommended" method="post">
<select name="recommended[]" class="chosen-select" multiple title='Select Skills' multiple style="width: 100%;">
<?php for ($i = 0; $i < count($users); $i++) { ?>
<option value="<?php echo $users[$i]->userID ?>"><?php echo $users[$i]->username ?></option>
<?php } ?>
</select>
</form>
I completely changed my database and my PHP function for multi select
