I have function to fetch the products from ci_products table
the code is as follows
function get_product_selections($product_ids = array())
{
$this->db->select('*');
$this->db->from('ci_products');
$this->db->where_in('product_id', $product_ids);
$products = $this->db->get();
return $products;
}
now I want to fetch from where user_id is current user_id
I have tried few things but not working
what I have tried`
function get_product_selections($product_ids = array())
{
$this->db->select('*');
$this->db->from('ci_products');
$this->db->where_in('product_id', $product_ids);
$this->db->where('user_id',$this->session->userdata('user_id'));
$products = $this->db->get();
return $products;
}
$data = $this->db->get_where('product_ids',$product_ids);
$this->db->where_in('product_ids',$data);
$this->db->where('user_id',$this->session->userdata('user_id'));
$query = $this->db->get();
return $query->result_array();
Try this one :
In your first code:
function get_product_selections($product_ids)
{
$this->db->select('*');
$this->db->from('ci_products');
$this->db->where('product_id', $product_ids);
$products = $this->db->get();
return $products->result_array();
}
what do you mean when you put array() in the parameter? you want to retrieve an array() of products?
function get_product_selections()
{
$this->db->select('*');
$this->db->from('ci_products');
$this->db->where('user_id',$this->session->userdata('user_id')); // the user who is currently login
$products = $this->db->get();
return $products->result_array(); // return the results
}

public function cmplFirstRdDetails($userMobileNo) {
$this->db->from('records');
$this->db->like('player1', '{"PhoneNumber":"$userMobileNo"}');
$query = $this->db->get();
return $query->result();
}
This code is not working for me.
I want to create a join database. in the 'relation' table will show 'disease' which can add many 'symptoms'. How should I do it?
Here is my database:
disease : id_disease, name, details
symptoms : id_symptoms, name, details
relation : id_relation, id_disease, id_symptoms
and here is my model
function get_allrelation() {
$this->db->select('*');
$this->db->from('relation');
$this->db->join('disease','disease.id_disease = relastion.id_disease','left');
$this->db->join('symptoms','symptoms.id_symptoms= relation.id_symptoms','left');
$query = $this->db->get();
return $query->result();
}
}
Please help me.
You had a typo: instead of relation you had relastion.id_disease.
Code below should work
function get_allrelation() {
$this->db->select('*');
$this->db->from('relation');
$this->db->join('disease','disease.id_disease = relation.id_disease','left');
$this->db->join('symptoms','symptoms.id_symptoms= relation.id_symptoms','left');
$query = $this->db->get();
return $query->result();
}
The controller below is a example only in the select $this->db->select('relation.*, disease.*, symptoms.*');
Oon the controller you can pass the data to the view the create a foreach loop in the view.
<?php
class Somecontroller extends CI_Controller {
public function index() {
$data['allrelation'] = $this->allrelation();
$this->load->view('example', $data);
}
function get_allrelation() {
$this->db->select('relation.*, disease.*, symptoms.*');
$this->db->from('relation');
$this->db->join('disease','disease.id_disease = relastion.id_disease','left');
$this->db->join('symptoms','symptoms.id_symptoms = relation.id_symptoms','left');
$query = $this->db->get();
if ($query->num_rows() > 0) {
return $query->result();
}
return false
}
}
I have this function in model
function select($table,$match,$or){
$this->db->select('*');
$this->db->from($table);
$this->db->where($match)->or_where($or);
$query = $this->db->get();
$query_result = $query->result();
return $query_result;
}
and in controller
$post = array("class"=>"XI","section"=>"A","stream"=>"Medical");
$data = $this->main_model->select("class_subjects",array("class"=>$post['class'],"section"=>"all","stream"=>$post['stream']),$post);
print_r($data);
I am not getting any error but this is printing whole data of table. how can i match class='XI' and stream='Medical' and (section='A' or section='all')
Try this
function select($table,$match,$or)
{
$query = $this->db
->select("*")
->from($table)
->group_start()
->where($match)
->group_end()
->group_start()
->or_where($or)
->group_end()
->get();
$strSql = $this->db->last_query();
return $query->result();
}
if that won't work - print out the $strSql Variable and post the Query here.
I'm having a little trouble in retrieving data in multiple tables using codeigniter.
This is the code i'm using to retrieve data in my model which is working well.
function retrieve_experience($alumni_id)
{
$this->db->select('*');
$this->db->from('experience');
$this->db->where('alumni_id',$alumni_id);
$query = $this->db->get();
return $query;
}
function retrieve_education($alumni_id)
{
$this->db->select('*');
$this->db->from('education');
$this->db->where('alumni_id',$alumni_id);
$query = $this->db->get();
return $query;
}
Now i tried using a simplified code but fails to display the data. here is the code in my model
function retrieve_all_data($alumni_id)
{
$this->db->select('*');
$this->db->from('experience');
$this->db->join('education','education.alumni_id=experience.alumni_id');
$this->db->where('experience.alumni_id',$alumni_id);
$query=$this->db->get();
return $query->result_array();
}
In my controller, i used this code to retrieving data in my model
function display()
{
$alumni_id = $this->session->userdata('alumni_id');
$data['all_data'] = $this->Alumni_model->retrieve_all_data($alumni_id);
$data['main_content'] = 'alumni_home';
$this->load->view('includes/template', $data);
}
and for the display i used this code
foreach($all_data as $results)
{
/** data from experience table **/
$results['company_name'];
$results['company_address'];
/** data from education table **/
$results['school_name'];
$results['field_of_study'];
}
I cant display anything at all. Please help
Try the below code,
I believe you'll want something like this:
function retrieve_all_data($alumni_id)
{
$this->db->select("e.*,edu.*");
$this->db->from("experience e");
$this->db->join("education edu", "edu.alumni_id = e.alumni_id",'left');
$this->db->where('e.alumni_id',$alumni_id);
$this->db->group_by('e.exp_id');
$query = $this->db->get();
return $query->result_array();
}
Hope below mentioned function should return data that you expected.
function retrieve_all_data($alumni_id)
{
$this->db->select('*');
$this->db->from('experience ex');
$this->db->join('education ed','ed.alumni_id=ex.alumni_id');
$this->db->where('ex.alumni_id',$alumni_id);
$query=$this->db->get();
return $query->result_array();
}
this my
model
public function get_news($NewsId= FALSE)
{
if ($NewsId === FALSE)
{
$this->db->select('*');
$this->db->from('news');
$this->db->where('Status' , 1);
$this->db->where('Language' , 2);
return $query->result_array();
$config['per_page']; $this->uri->segment(3);
}
$query = $this->db->get_where('news', array('NewsId' => $NewsId));
return $query->row_array();
controller
public function single($NewsId)
{
$data['news_item'] = $this->news_model->get_news($NewsId);
if (empty($data['news_item']))
{
show_404();
}
$data['NewsId'] = $data['news_item']['NewsId'];
$this->load->view('news/single', $data);
}
view
<?php echo $news_item['TittleNews'];?>
i have other view that foreach all my news table and i want create read more the i have created on up my code it works fine
want to make read more with NewsId and one other column it mean first check the NewsId and then other colum and then show me on my view which is singly
you can use a model method like this:
function getBy($data){
foreach($data as $key=>$value){
$this->db->where($key,$value);
}
$query = $this->db->get('users_table');
return $query->row(); //or $query->result(); as you want
}
so then you call it with
$this->model->getBy(
array(
'username'=>'Mark',
'id'=>'90',
'email'=>'asd#asd.com'
);
);
obviously you can then extend the model method as much as you can
