How to read value in combobox when editing data with codeigniter - php

Question

I can't show the data that I want to edit from my table. The combobox and the table don't show data when I edit the data categories, sub-categories, and manufacturers. I want to be able to see the data from my table after editing.
Controller form
public function data_items_edit($id)
{
$this->load->model('additem_m');
$model3 = $this->additem_m;
$data['table'] = $model3->get_where2($id)[0];
//$data['table'] = $model3->get();
$this->load->model('category_m');
$model = $this->category_m;
$data['category'] = $model->get();
$this->load->model('subcategory_m');
$model1 = $this->subcategory_m;
$data['sub'] = $model1->get();
$this->load->model('manufactures_m');
$model2 = $this->manufactures_m;
$data['manu'] = $model2->get();
//print_r($data['table']);
$this->load->view('items/edit_items_v', $data);
}
Data table controller
public function index()
{
if($this->session->has_userdata('isLogin')){
$this->load->model('additem_m');
$model = $this->additem_m;
$data['table'] = $model->get('items.*, item_categories.name as ic,
item_categories_sub.name as ics, item_manufactures.name as im',
[
['table'=>'item_categories','condition'=>'item_categories.id =
items.item_category_id'],
['table'=>'item_categories_sub','condition'=>'item_categories_sub.id
= items.item_category_sub_id'],
['table'=>'item_manufactures','condition'=>'item_manufactures.id =
items.item_manufacturer_id'],
]);
//print_r($data['table']);
$this->load->view('items/items_v', $data);
}else{
redirect('login');
}
}

Answer 1

You have to add selected attribute to the options.
$category == $category->id ? "selected" : ""
Something like this
<?php
foreach($category as $category){
echo '<option value="'.$category->id.'" '. $category == $category->id ? "selected" : "" .'>'.$category->name.'</option>';
^ ^
}
?>
