I have a query that I use to get my data from two tables. How can I use the codeigniter active records "Join" instead of my query
public function get_categories($parent_id = 0) {
$query = $this->db->query("SELECT * FROM " . $this->db->dbprefix . "category c LEFT JOIN " . $this->db->dbprefix . "category_description cd ON (c.category_id = cd.category_id) WHERE c.status=1 and c.parent_id = '" . (int)$parent_id . "' order by sort_order");
return $query->result_array();
}
Question: What would be the best to convert it to codeigniter active records "Join" function.
Try this
$this->db->select('*');
$this->db->from($this->db->dbprefix.'category c');
$this->db->join($this->db->dbprefix.'category_description cd', 'c.category_id = cd.category_id');
$this->db->where('c.status',1);
$this->db->where('c.parent_id',$parent_id);
$this->db->order_by("sort_order", "asc");
$query = $this->db->get();
return $query->result_array();
$this->db->select('*');
$this->db->from($this->db->dbprefix.'category c');
$this->db->join($this->db->dbprefix.'category_description cd', 'c.category_id = cd.category_id');
$this->db->where(array('c.status' => 1 ,'c.parent_id' => $parent_id));
$this->db->order_by("sort_order", "asc");
$query = $this->db->get()->result_array();
print_r($query);

Im working on product filtering using AJAX. Is there any possible way to produce same output as picture shown below using query builder?
I have tried union but it’s not working.
I hope this example gives idea , Try this one
use multiple if statement and get data into DB using joins .
function datatables($request) {
$data = $this->leftJoin('blog_category', 'blog_category.blog_category_uuid', '=', 'blog_detail.blog_category_uuid')
->where('blog_detail.blog_detail_is_deleted', 'NO');
if ($request->search['value'] != null && $request->search['value'] != '') {
$keyword = $request->search['value'];
$data = $data->where(function($query) use ($keyword) {
// $query->orWhere('activity_type.activity_type_name', 'LIKE', '%' . $keyword . '%');
$query->orWhere('blog_detail.blog_detail_title', 'LIKE', '%' . $keyword . '%');
});
}
if (isset($request->order[0]['dir'])) {
$data = $data->orderBy('blog_detail.blog_detail_id', $request->order[0]['dir']);
} else {
$data = $data->orderBy('blog_detail.blog_detail_created_date');
}
$datacount = $data->count();
$dataArray = $data->select('blog_detail.*', 'blog_category.blog_category_name' , DB::raw('DATE_FORMAT(blog_detail.blog_detail_created_date,"%Y-%m-%d") as blog_detail_date'));
if ($request->length == -1) {
$dataArray = $dataArray->get();
} else {
$dataArray = $dataArray->skip($request->start)->take($request->length)->get();
}
return [$datacount, $dataArray];
}
In laravel you can create a model for product say Product. Then the query will be like
$products = Product::where('product_status', '1');
if ($request->input('minimum_price') && $request->input('maximum_prize')) {
$products = $products->whereBetween('product_prize', array($request->input('minimum_price'), $request->input('maximum_prize')));
}
if ($request->input('brand')){
$brand_filter = implode("','", $request->input('brand'));
$products = $products->whereIn('product_brand', $brand_filter);
}
$products = $products->get();
after the execution $products contains the products after query.
How to use Below query in Codeigniter
SELECT * FROM (post) JOIN user ON user.user_id=post.user_id JOIN friend ON (friend.user_id=post.user_id AND friend.friendship_id=1) OR (friend.user_id=1 ANDfriend.friendship_id=post.user_id) WHERE post.type = 'friend' ORDER BY postid desc
You can use this.
$this->db->query(your query);
like this code.
$sql = "SELECT * FROM table WHERE user_id = 1";
$this->db->query($sql);
try this
$query = $this->db
->select('*')
->from('post')
->join('user', 'user.user_id = post.user_id')
->join('friend', 'friend.user_id = (post.user_id AND friend.friendship_id=1) OR (friend.user_id = 1 AND friend.friendship_id = post.user_id)')
->where('post.type', 'friend')
->order_by('postid','DESC')
->get();
$arrResult = $query->result();
So this code is a combination of 3 table joined, now i want to filter the query where only the request that a user can have is his/her own request and not from other user.. the problem is in where clause i have duplicated.
$this->db->order_by('loanrequest.ApplicationNo', 'DESC');
$query = $this->db->get('loanrequest','loanapplication','user');
$this->db->join('loanapplication','loanrequest.ApplicationNo = loanapplication.ApplicationNo');
$this->db->join('user', 'user.userId = loanapplication.userId');
$this->db->where('loanapplication.userId', $this->session->userdata('userId'));
$this->db->where('loanapplication.ApplicationNo', 'loanrequest.ApplicationNo');
return $query->result_array();
I can not get what you have done in your join query but Here is how I do join in my CodeIgniter model.
You don't need to put this in where condition:
$this->db->where('loanapplication.ApplicationNo', 'loanrequest.ApplicationNo');
Because you have already done that in the join query.
$query = $this->db->select('*')
->from('loanapplication')
->join('loanrequest', 'loanrequest.ApplicationNo = loanapplication.ApplicationNo', 'left')
->join('user', 'user.userId = loanapplication.userId', 'left')
->where_in('loanapplication.userId',$this->session->userdata('userId'))
->order_by('loanrequest.ApplicationNo', 'DESC')
->get();
return $query->result_array();
I will recommend you should use $this->db->last_query() because it gives you a better idea about your query.
$query = $this->db->select('*')
->from('loanapplication')
->join('loanrequest', 'loanrequest.ApplicationNo = loanapplication.ApplicationNo', 'left')
->join('user', 'user.userId = loanapplication.userId', 'left')
->where_in('loanapplication.userId',$this->session->userdata('userId'))
->order_by('loanrequest.ApplicationNo', 'DESC');
$result = $query->get();
echo $this->db->last_query();exit; //use this to print your query so that you can get the actual issue
if ($result->num_rows() > 0) {
return $result->result_array();
} else
return '';
I am using codeigniter 3.1.0 and I am trying to get the total SUM of two columns from different tables
If my user_id = 1 it should return the total sum of 421 but returns 431 It is adding the votes from other users on my reply table
Question Using Active Record How can I make sure the SUM is getting the correct amount for the users id.
Model Function
public function thread_reputation($user_id) {
$this->db->select('SUM(reply.votes + thread.votes) AS reputation');
$this->db->from('thread', 'left');
$this->db->join('reply', 'reply.user_id = thread.user_id', 'left');
$this->db->where('thread.user_id', $user_id);
$this->db->where('reply.user_id', $user_id);
$query = $this->db->get();
if ($query->num_rows() > 0) {
return $query->row();
} else {
return 0;
}
}
Controller section where i echo it
$thread_reputation = $this->thread_analytics_model->thread_reputation('1');
echo $thread_reputation->reputation;
Thread Table
Reply Table
Change your query with this
$query = $this->db->query("SELECT SUM(A.votes) as reputation from
(
SELECT reply.votes FROM reply where reply.user_id = $user_id
UNION ALL
SELECT thread.votes FROM thread where thread.user_id = $user_id
)AS A");
Tested and properly working
Check Screenshot:-
Query using ACTIVE REOCRD
$this->db->select("SUM(A.votes) as reputation");
$this->db->from("(
SELECT reply.votes FROM reply where reply.user_id = $user_id
UNION ALL
SELECT thread.votes FROM thread where thread.user_id = $user_id) AS A");
$query = $this->db->get();
Another Solution using $this->db->get_compiled_select();
public function reputation($user_id) {
$this->db->select('thread.votes');
$this->db->from('thread');
$this->db->where('thread.user_id =' . $user_id);
$thread_query = $this->db->get_compiled_select();
$this->db->select('reply.votes');
$this->db->from('reply');
$this->db->where('reply.user_id ='. $user_id);
$reply_query = $this->db->get_compiled_select();
$query = $this->db->query("SELECT SUM(total.votes) as reputation from ($reply_query UNION ALL $thread_query) as total");
if ($query->num_rows() > 0) {
return $query->row();
} else {
return 0;
}
}
When you will use left join, it will return matched column & all other unmatched column from left table. Use inner join & check your result.
Hello i have this join, but i wanna join another tabel named "users" and i want the "profil_billed" row, how can i do that
i mean "WHERE forum_traad.brugernavn = users.profil_billed" something like that
function posts($id)
{
$this->db->select('*,forum_traad.indhold as traad_indhold,
forum_kommentare.indhold as kommentare_indhold,
forum_traad.brugernavn as traad_brugernavn,
forum_traad.id as traad_id
');
$this->db->from('forum_traad');
$this->db->join('forum_kommentare', 'forum_kommentare.fk_forum_traad', 'forum_traad.id');
$this->db->where('forum_traad.id', $id);
$query = $this->db->get();
if($query->num_rows > 0)
{
return $query->row();
} else {
return false;
}
}
You can write your query as below -
$this->db->select('*,forum_traad.indhold as traad_indhold,
forum_kommentare.indhold as kommentare_indhold,
forum_traad.brugernavn as traad_brugernavn,
forum_traad.id as traad_id, users.profil_billed as billed
');
$this->db->from('forum_traad');
$this->db->join('forum_kommentare', 'forum_kommentare.fk_forum_traad = forum_traad.id');
$this->db->join('users', 'forum_traad.brugernavn = users.profil_billed');
$this->db->where('forum_traad.id', $id);
$query = $this->db->get();
