I want to do inner join between estate table and estatetype table. I make a edit page but I want to show customer information by cusId. I can draw data from estate table. But estateType in estate table. I hold estateType names in estatetype table. When I call estateType from estate table, just showing number(1,2,3) But I want to show their names from estatetype table. How I can do it?
I want to show customer estate information by Id from estatetype table. But I cannot do this.
Controller:
$viewData = new stdClass();
$this->load->model('join_model');
$viewData->estateList = $this->join_model->estatetypes();
$viewData->customers = $this->db->where("cusId", $cusId)->get("customer")->row();
$viewData->property = $this->db->where("cusId", $cusId)->get("estate")->row();
$viewData->estype = $this->db->get("estatetype")->result();
$viewData->heating = $this->db->get("heating")->result();
$viewData->cities = $this->db->get("city")->result();
$this->load->view('property_edit',$viewData);
Model:
<?php
class Join_model extends CI_Model {
public function __construct()
{
parent::__construct();
}
public function estatetypes()
{
$this->db->select('estate.CusId,estate.estateType,estatetype.estateTypeId,estatetype.estateTypeAr,estatetype.estateTypeEng');
$this->db->from('estate');
$this->db->join('estatetype', 'estate.estateType = estatetype.estateTypeEng');
$results = $this->db->get()->row();
return $results;
//return $this->db->get_where('users', array('userId' => $id), 1);
}
}
I want to show when I add estateType from estate table in view, show estataTypeEn from estateType. For this, I did the inner join but when I add this to view and controller. There is nothing. How do I do this?
View:
<!-- Basic select -->
<div class="form-group">
<label class="control-label col-lg-3">Estate Type <span class="text-danger">*</span></label>
<div class="col-lg-9">
<select name="estateType" class="form-control">
<option value="<?php echo $property->estateType; ?>" readonly><?php echo $estateList->estateType; ?></option>
<?php
foreach($estype as $etype){ ?>
<option value="<?php echo $etype->estateTypeId; ?>"><?php echo $etype->estateTypeEng; ?></option>
<?php }?>
</select>
</div>
</div>

You don't need to use Join you can create a custom_helper.php
A CodeIgniter helper is a PHP file with multiple functions. It is not a class
Create a file and put the following code into it.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
if ( ! function_exists('get_name'))
{
function get_name($id,$value)
{
$CI=& get_instance();
$number_data = $CI->db->get_where('estatetype', array('estateTypeId' => $id))->num_rows();
if($number_data > 0){
$data = $CI->db->get_where('estatetype', array('estateTypeId' => $id))->row()->$value;
}
else{
$data = translate('Not_Found');
}
return $data;
}
}
Save this to application/helpers/ .
Load this in your controller
$this->load->helper('custom_helper');
If you use this helper in a lot of locations you can have it load automatically by adding it to the autoload configuration file i.e. <your-web-app>\application\config\autoload.php.
$autoload['helper'] = array('custom_helper');
And in your view, you can call this function like this.
<select name="estateType" class="form-control">
<?php
$estype = $this->db->get("estate")->result_array();
foreach($estype as $row){ ?>
<option value="<?php echo $row['estateType']; ?>"><?php echo get_name($row['estateType'],'estateTypeNameEn'); ?></option>
<?php }?>
</select>
if you want to get other table or other columns from a table you can change the function like this.
function get_name($table,$field,$equal,$value)
{
$CI=& get_instance();
$number_data = $CI->db->get_where($table, array($field => $equal))->num_rows();
if($number_data > 0){
$data = $CI->db->get_where($table, array($field => $equal))->row()->$value;
}
else{
$data = translate('Not_Found');
}
return $data;
}
and in view you can add this.
<select name="estateType" class="form-control">
<?php
$estype = $this->db->get("estate")->result_array();
foreach($estype as $row){ ?>
<option value="<?php echo $row['estateType']; ?>"><?php echo get_name('estatetype','estateTypeId',$row['estateType'],'estateTypeNameEn'); ?></option>
<?php }?>
</select>
