Return only single record on codeigniter

Question

How can I return only 1 record on this statement?

public function edititem($id){
   $this->db->select('*');
   $query = $this->db->get('tblitem');
   $this->db->where('item_id',$id);

   foreach ($query->result() as $row){
        echo $row->item_id.'</br>';
        echo $row->item_name.'</br>';
        echo $row->item_description.'</br>';
        echo $row->item_price.'</br>';
   }
}

It gives me all the records instead

Answer 1

For fetching single row form table use ->row()

function edititem($id) {
    $this->db->select('item_id,item_name, item_description,item_price');
    $this->db->where('item_id', $id);
    $this->db->limit(1);// only apply if you have more than same id in your table othre wise comment this line
    $query = $this->db->get('tblitem');
    $row = $query->row();

    echo $row->item_id . '</br>';
    echo $row->item_name . '</br>';
    echo $row->item_description . '</br>';
    echo $row->item_price . '</br>';
}

Answer 2

Use $this->db->limit(1); to get 1 record only.

Answer 3

Use these

Method 01 - $this->db->get()

$query = $this->db->get('tblitem' ,1 , 0); # Set Limit

Method 02 - $this->db->limit() in CI

$this->db->limit(1);

Method 03 - Result Rows in CI

$row = $query->first_row('array');
$row = $query->last_row('array');
$row = $query->next_row('array');
$row = $query->previous_row('array');

These will only produce one set of data. and in your foreach loop it will always return one

Answer 4

Use limit , so sql will return you the only first row found, but not the whole set of rows. The CI's manual is explicit about getting results.

here're two one-liner solutions, through the get() :

// ... other query conditions
$this->db->limit(1)->get('tblitem')->row()->your_key;

// or with the short syntax for defining limit, through the get:
$this->db->get('tblitem', 1, 0)->row()->your_key;

if you need to reference several values later on, assign result of row() to variable, to re-use later.

$row = $this->db->limit(1)->get('tblitem')->row();

Answer 5

Use this:

$this->db->get()->custom_row_object(0, 'Your_Model');

The code above is mentioned by the codeigniter user guide. The best about this is no need to loop foreach where you can get very specific row value.
