无法在Codeigniter中更新数据库查询

Question

I have to fetch the record from the form of an array. following is an array result.

Array(
    [price] => Array
    (
        [0] => 210
    )

    [code] => Array
    (
        [0] => SER-1001
    )
)
Array
(
    [price] => Array
    (
        [1] => 80
    )

    [code] => Array
    (
        [1] => XYZ-121
    )
)

Now I am confused, how to update that records in product table where a code is eg SER-1001 in the database then the price should be updated 210 .

Same way as I do rest of matching code records.

Answer 1

foreach ($arr as $key => $value) {
  $data = array(  
    'price'=> $value['price'];
  );  
  $this->db->where('code', $value['code']);  
  $this->db->update(‘database-table-name’,$data);   
}

try this, here you are looping through the array and updating the data one by one.

Answer 2

    $array = [
     [
        'price' => [ '0' => 210],
        'code' =>['0' => 'SER-1001']
    ],
    [
        'price' => ['1' => 80],
        'code' =>['1' => 'XYZ-121']
    ]
];

With reference to the above output array. You can write the code something like this.

$counter = 0;
foreach($array as $data)
{
    if(isset($data['code'][$counter]))
    {
        $code = $data['code'][$counter];

        $data = [
            'price' => $data['price'][$counter];
        ];

        $this->db->where($column, $code);

        $this->db->update('database-table-name',$data);  
    }

    $counter++;
}
