How to pass multiple array of Id in where condition codeigniter? - php

I want to pass multiple id in where condition how to do it?
A query fetches org_id from database.
now I want to pass that in my where condition, so how to do it?
I tried foreach loop:
Below is my code:
$devices = $this->activation_m->get_activated_devices();
$org_id = array(); // create org_id array
foreach ($devices as $row)
{
$org_id[]= $row['org_id']; // assign ids into array
//$companys =$this->data['devices'] = $this->activation_m->get_company($org_id); // don't call again and again
}
//Now $org_id is array
$companys =$this->data['devices'] = $this->activation_m->get_company($org_id);
echo $this->db->last_query();
Model Code
public function get_activated_devices()
{
$this->db->select('*');
$this->db->join('sitekey','sitekey.site_key = activation.site_key');
$this->db->from('activation');
$query =$this->db->get();
$result = $query->result_array();
return $result;
}
public function get_company($org_id)
{
$this->db->select('*');
$this->db->join('sitekey','sitekey.org_id = company.id');
$this->db->join('activation','sitekey.site_key = activation.site_key');
$this->db->where('company.id IN',(implode(',',$org_id))); // see the change here
$this->db->from('company');
$query =$this->db->get();
$result = $query->result_array();
return $result;
}
now currently my query passes only one org_id , I want to pass all the org_id I get from my first query.

You can use where_in from active-records codeigniter
as
$devices = $this->activation_m->get_activated_devices();
$org_id = array();
foreach ($devices as $row)
{
$org_id[] = $row['org_id'];
}
$companys =$this->data['devices'] = $this->activation_m->get_company($org_id);
if( $companys->num_rows() > 0 )
{
echo "<pre>";
print_r( $companys->result());
echo "</pre>";
}
And for Model
public function get_company($org_ids = array())
{
$this->db->select('*');
$this->db->join('sitekey','sitekey.org_id = company.id');
$this->db->join('activation','sitekey.site_key = activation.site_key');
$this->db->where_in('company.id', $org_ids ); //this is condition
$this->db->from('company');
return $this->db->get();
}

You can use codeigniter's $this->db->or_where() for the purpose. Just traverse the array of organization id's and apply or_where conditions.
$this->db->select('*');
$this->db->join('sitekey','sitekey.org_id = company.id');
$this->db->join('activation','sitekey.site_key = activation.site_key');
foreach($org_id as $org)
{ // where $org is the instance of one object of active record
$this->db->or_where('company.id',$org);
}
$this->db->from('company');
$query =$this->db->get();
$result = $query->result_array();
return $result;
Another way to do this is to make a custom query by traversing the array like this and appending where clauses in string.

How do I build this array to output?

I have the following function which fetches some data from a MySQL table:
function readQuestion ($quizType, $questionId) {
$data = array();
$query = $this->dbConnection->query("SELECT * FROM $quizType WHERE id = $questionId");
foreach ($query as $row) {
var_dump($row);
};
echo $data
}
How can I push all the returned data into an array, where each member is indexed by a number?
Do I need to use echo or return at the end? They seem to have the same effect.
EDIT: Is this the correct way of returning results of the query? I am passing it to the front-end.
$questionData = $controller->readQuestion($quizType, $questionId);
return $questionData;
In general your function must looks like:
function readQuestion ($quizType, $questionId) {
$data = array();
$query = $this->dbConnection->query("SELECT * FROM $quizType WHERE id = $questionId");
return $query;
}
But, you have to look what is inside $query variable. If it is array - just return this array, if not - maybe it is some iterator, hence you have to check it and try to find method like toArray or something like that... Otherwise, you have to do something like:
$data = [];
foreach ($query as $row) {
$data[] = $row;
};
return $data;
Now you can use this function like:
var_dump(readQuestion($quizType, $questionId));
Take a look up here on how to secure your data.
Anyway, as I said in the comment you cannot use echo on an Array. And you can't do anything with the output of var_dump.
Change var_dump($row); for $data[] = $row;
and change echo $data; for return $data;
function readQuestion ($quizType, $questionId) {
$data = array();
$query = $this->dbConnection->query("SELECT * FROM $quizType WHERE id = $questionId");
foreach ($query as $row) {
$data=$row;
};
return $result;
}

Navigate an array from controller in Codeigniter

Good I'm starting with php and codeigniter, I have the following problem I'm running an array from my model, which is the result of a query, how can I read one by one my records in the controller?
function getCustomers() {
$sql = "SELECT * FROM customers";
$query = $this->db->query($sql);
if ($query->num_rows() > 0) {
$i = 0;
foreach($query->result() as $row) {
$img[$i]['id'] = $row->id;
$img[$i]['name'] = $row->name;
$img[$i]['Location'] = $row->Location;
$img[$i]['telephone'] = $row->telephone;
$i++;
}
return $img;
}
}
You can return array to the controller by loading the model into the controller like this.
$this->load->model('yourmodel');
$array = $this->yourmodel->yourmodelsmethod();
First you have to return this array to your controller like
$this->load->model('yourmodel');
$array['test'] = $this->yourmodel->yourmodelsmethod();
foreach($test as $key=>$value)
{
echo $value;
}
By doing this you can easily print your data from model in controller

Return the highest value from model to view

I want to know how to compare these 2 outputs http://prntscr.com/bx7ay9 and return the highest value in the array ?
MY MODEL CODES
$this->db->select('additional');
$this->db->from('order_detail');
$this->db->where('order_id',$id);
$query = $this->db->get();
foreach ($query->result() as $row)
{
$return[] = $row->additional;
}
return $return;
Just use select_max in query to get highest value and use row() to fetch single row without using foreach loop as
$this->db->select_max('additional AS max_value');
$this->db->from('order_detail');
$this->db->where('order_id', $id);
$query = $this->db->get();
$ret = $query->row();
return $ret->max_value;
$this->db->select('additional');
$this->db->from('order_detail');
$this->db->where('order_id',$id);
$query = $this->db->get();
foreach ($query->result() as $row)
{
$return[] = max($row->additional);
}
return $return;
Just used select_max of Codeigniter Query Bulder Class.
Model,
public function get_max ($id){
$this->db->select_max('additional');
$this->db->where('order_id',$id);
$query = $this->db->get('order_detail');
return $query->row();
}
In Controller,
$max = $this->Model->get_max($id);
echo $max['additional']; // Display and see the value.
If you want to get the max number then use select_max(),
$this->db->select_max('additional');
$this->db->from('order_detail');
$this->db->where('order_id',$id);
$query = $this->db->get();
if($query->num_rows()){// check if data is not empty
return $query->row()->additional;
}
return false;// you can return false here
And if you want to get the result array for another use then, you can use max() with $this->db->select('additional'); with your code to get the max number in array.

Can i get a part of an variable?

Is it possible to get an part of a variable and run this to a where loop.
function rapport_detail_kosten($idKlant){
$this->db->from('Project');
$this->db->join('Kosten', 'Kosten.idProject = Project.idProject');
if ($idKlant > 0){
$this->db->where('idKlant', $idKlant);}
$query = $this->db->get();
$project = array();
foreach($query->result() as $row){
$project[] = $row->idProject;
}
$hoi = implode(",", $project);
print_r($hoi);
$this->db->select_sum('Prijs');
$this->db->from('Kosten');
$this->db->where('Kosten.idProject',$hoi);
$query = $this->db->get();
if($query->num_rows()>0){
return $query->result();
}
else{
return false;
}
}
the $hoi has the value: 14,79,9,85,85,85,85,91,6
these are all id's but i would like to run this where statement only when the id is in this variable. So i would like to run id=6 but for example not id=7
You can use method where_in of codeigniter that search a value inside an array, in this case you can use directly $project, you don't need $hoi
try this:
$sum = 0;
$this->db->select_sum('Prijs');
$this->db->from('Kosten');
$this->db->where_in('Kosten.idProject',$project);
$query = $this->db->get();
foreach ($query->result() as $row){
$sum = $row->Prijs;
}
return($sum);

What is wrong with this PHP code?

I have two database tables, one for allowances and one for deductions. I want to calculate net salaries.
I'm using CodeIgniter. Here's my current code:
function get_allowances($eid)
{
$this->db->from('allowances');
$this->db->where('eid',$eid);
$query = $this->db->get();
if($query->num_rows()==1)
{
return $query->row();
}
else
{
//Get empty base parent object, as $item_id is NOT an item
$salary_obj=new stdClass();
//Get all the fields from items table
$fields = $this->db->list_fields('allowances');
foreach ($fields as $field)
{
$salary_obj->$field='';
}
return $salary_obj;
}
}
function get_deductions($eid)
{
$this->db->from('deductions');
$this->db->where('eid',$eid);
$query = $this->db->get();
if($query->num_rows()==1)
{
return $query->row();
}
else
{
//Get empty base parent object, as $item_id is NOT an item
$salary_obj=new stdClass();
//Get all the fields from items table
$fields = $this->db->list_fields('deductions');
foreach ($fields as $field)
{
$salary_obj->$field='';
}
return $salary_obj;
}
}
and in controller,
function net_salary($eid)
{
$allownces[] = $this->Salary->get_allowances($eid);
$deductions[] = $this->Salary->get_deductions($eid);
return $net_salary = array_sum($allownces) - array_sum($deductions);
}
My net_salary() function gives me a result of 0. What am I doing wrong, and how can I fix it?
Your models with plural names are only going to return a single object.
so what you are ending up with is...
Array
(
[0] => allowance_object
)
and
Array
(
[0] => deduction_object
)
While we really need the schema of your database try this (and make same edits for deductions)...
function get_allowances($eid)
{
$this->db->from('allowances');
$this->db->where('eid',$eid);
$query = $this->db->get();
if($query->num_rows()==1)
{
return $query->row_array(); //<--- return an Array
}
else
{
// make an array instead of object
$salary_obj = array();
//Get all the fields from items table
$fields = $this->db->list_fields('allowances');
foreach ($fields as $field)
{
$salary_array[$field] = 0; //<---- add array keys and set to integer 0 instead of empty string.
}
return $salary_array;
}
}
then in your net_salary function
function net_salary($eid)
{
$allownce = $this->Salary->get_allowances($eid);
$deduction = $this->Salary->get_deductions($eid);
return array_sum($allownce) - array_sum($deduction);
}
Try something like this:
function get_values($eid, $table_name)
{
$this->db->where('eid',$eid);
$query = $this->db->get($table_name);
$salary_obj = $query->result();
$values = array();
foreach($salary_obj as $row){
$values[] = $row->value_column_name;
}
return $values;
}
where value_column_name is the name of the table column (filedname) where the desired value stands.
call in controller:
function net_salary($eid)
{
$allownces = $this->Salary->get_values($eid, 'allowances');
$deductions = $this->Salary->get_values($eid, 'deductions');
return $net_salary = array_sum($allownces) - array_sum($deductions);
}
