How to get an id of the user in Codeigniter? - php

Question

This is actually very easy but yet I am confused how to do this:
I have Reseller that can request X-number of users to admin. So that value gets saved to database. Now when admin logs in he can see the requests of resellers. Like this :
Now Admin Can either approve or reject the request. If He approves the request the code creates users in users table mapped to that reseller. The mapping is done with a unique field called Key Now Creating users works perfectly but my problem is :
When I click on Approve it creates users but for only for the reseller wit id = 1. I want to create something like when I click on first record it creates users for 1st reseller and when on 2nd same as above[This is as per the image].
This is my view:
<?php if(count($users)): foreach($users as $user): ?>
<tr class="odd gradeX">
<td><?php echo $user->id; ?></td>
<td><?php echo $user->user_requested; ?></td>
<td><?php echo $user->key; ?></td>
<td><?php echo $user->date_requested; ?></td>
<td>Yes&nbsp<i class="glyphicon glyphicon-ok"></i></td>
<td>No&nbsp<?php echo'<i class="glyphicon glyphicon-trash"></i>';?></td>
<td><?php echo $user->status; ?></td>&nbsp</td>
</tr>
<?php endforeach; ?>
<?php else: ?>
<tr>
<td colspan="3">There are no new Requests.</td>
</tr>
<?php endif; ?>
The Controller
public function create_user()
{
$this->load->model('more_m');
$id= $this->session->userdata('id');
$rajan =$this->more_m->get(array('user_requested',$id));
$request=$rajan->user_requested;
$this->load->model('reseller_m');
$query=$this->db->select('key');
$query=$this->db->get('reseller');
if($query->num_rows() > 0)
{
$row = $query->row_array();
$key= $row['key'];
}
for($i=1; $i<=$request;$i++)
{
$userdata=array('key'=>$key);
$this->db->insert('users',$userdata);
}
$this->load->model('more_m');
$id = $this->session->userdata('id');
$this->db->set('status', "'approved'",FALSE);
$this->db->where('id',$id);
$this->db->update('user_request');
redirect('admin/new_user');
}
My mistake is in controller where I define $id. As when admin logs in his id would be fetched I don't know how to fetch the id of the reseller as per the record.

Answer 1

Its so simple with Codeigniter
What you have to do is pass the ID with the URL (You are wrong Use base_url()as well with the pointing controller)
ex <td><a href="<?php echo base_url()?>reseller/create_user/<?php echo $user->key; ?>"
so now your URL looks like (assume id is equal to 2)
http://localhost/<path to project>/reseller/create_user/2
so in Controller
function create_user($id)//So this know incoming Value to this
{
//then in here
echo $id; //this will show 2
//Continue rest of your code with $id
}

If you wanna do it in php way,You can pass key in your url and get key in your controller using $this->uri->segment(n)
<?php if(count($users)): foreach($users as $user): ?>
<tr class="odd gradeX">
<td><?php echo $user->id; ?></td>
<td><?php echo $user->user_requested; ?></td>
<td><?php echo $user->key; ?></td>
<td><?php echo $user->date_requested; ?></td>
<td>Yes&nbsp<i class="glyphicon glyphicon-ok"></i></td>
<td>No&nbsp<?php echo'<i class="glyphicon glyphicon-trash"></i>';?></td>
<td><?php echo $user->status; ?></td>&nbsp</td>
</tr>
<?php endforeach; ?>
<?php else: ?>
<tr>
<td colspan="3">There are no new Requests.</td>
</tr>
<?php endif; ?>
If you want jquery+php than use ajax.
add value attr. to button pass your key.
<button id="some_id" value="YOURKEY">Click Me</button
This is your script to update :
<script>
$('body').on('click',"#some_id", function(){
var key =$(this).attr("value");
//Now you got ur key you can use ajax to update and change location of page on success
});
</script>
