Code Igniter- Batch Insert function inserts null fields in database - php

Question

Whenever i try to insert data, the fields of the two of the columns are null. ONLY the auto incremented(of course)MainReqID and the last column had the fields.
Here's my Controller..
public function insert_main($data,$orgs){
$this->db->insert('insert_main',$data);
$getID = $this->db->insert_id();
$ctr=1;
$insertorg = array();
foreach($i=0; $i<count($orgs); $i++){
$insertorg[] = array(
'OrgID'=>$ctr[$i],
'MainID'=>$getID[$i],
'Level'=>'1234'[$i]
);
$ctr++;
}
$this->db->insert_batch('insert_mainreq',$insertorg);
}
here's what it looks like in database...
MainReqID | OrgID | MainID | Level
1 | null | null | 1234
2 | null | null | 1234
3 | null | null | 1234
4 | null | null | 1234
5 | null | null | 1234.. and so on..
i need something like this..
MainReqID | OrgID | MainID | Level
1 | 1 | 3 | 1234
2 | 2 | 3 | 1234
3 | 3 | 3 | 1234
4 | 4 | 3 | 1234
5 | 5 | 3 | 1234.. and so on..

Answer 1

It looks like $getID is not an array but you are adding $getID[i]. This surely will not work. The same with $ctr. This is an integer but you are trying $ctr[i]. The same thing is happening with Level.
public function insert_main($data,$orgs){
$this->db->insert('insert_main',$data);
**$getID** = $this->db->insert_id();
**$ctr=1;**
$insertorg = array();
foreach($i=0; $i<count($orgs); $i++){
$insertorg[] array(
'OrgID'=>**$ctr[$i]**,
'MainID'=>**$getID[$i]**,
'Level'=>**'1234'[$i]**
);
$ctr++;
}
$this->db->insert_batch('insert_mainreq',$insertorg);
}
You could try this, I am not sure what you are trying to do with OrgId and MainID but:
public function insert_main($data,$orgs){
$this->db->insert('insert_main',$data);
$getID = $this->db->insert_id();
$insertorg = array();
foreach($i=0; $i<count($orgs); $i++){
$insertorg[] array(
'OrgID'=> $i,
'MainID'=>$getID,
'Level'=>'1234'
);
}
$this->db->insert_batch('insert_mainreq',$insertorg);
}
Keep in mind that $this->db->insert_id(); will return the id of the last row inserted if there are more than one row.

Try This Code:
public function insert_main($data,$orgs){
$this->db->insert('insert_main',$data);
$getID = $this->db->insert_id();
$insertorg = array();
foreach($i=0; $i<count($orgs); $i++)
{
$insertorg[] = array(
'OrgID'=> $i,
'MainID'=>$getID,
'Level'=>'1234'
);
}
$this->db->insert_batch('insert_mainreq',$insertorg);
}
