在数据库的新行中插入几个不同的值数组

Question

I want insert in the row from database, array of values as that each of they put in new row from database.

I not want insert all values in a row from database with use of serialize(json_encode or etc).

For example:(in this example, i want three times insert data(value), because i have 3 value different) Update 4:

this my value:

<input name="name[0][]" value="11">
<input name="passport_number[0][]" value="11">


<input name="name[1][]" value="22">
<input name="passport_number[1][]" value="22">

i do it, but it not worked:

$name_input = $this->input->post('name');
$passport_number_input        = $this->input->post('passport_number');
//$term_passport_input = $this->input->post('term_passport');
//$date_of_birth_input       = $this->input->post('date_of_birth');
//$age_input        = $this->input->post('age');
//$national_number_input = $this->input->post('national_number');
//$mobile_input       = $this->input->post('mobile');
//$address_input        = $this->input->post('address');

$data = array();
foreach ($name_input as $idx => $name) {
    $data[] = array(
        'name' => $name_input[0]
        'passport_number' => $passport_number_input[0],
        //'term_passport' => $term_passport_input[$idx],
        //'date_of_birth' => $date_of_birth_input[$idx],
        //'age' => $age_input[$idx],
        //'national_number' => $national_number_input[$idx],
        //'mobile' => $mobile_input[$idx],
        //'address' => $address_input[$idx],
    );
};
var_dump($name_input);
$this->db->insert_batch('customer_info', $data);

This is output '$name_input' with var_dump:

array(2) {
    [0] = > array(1) {
        [0] = > string(2)"11"
    }[1] = > array(1) {
        [0] = > string(2)"22"
    }
}

I get this error:

A PHP Error was encountered

Answer 1

Update 3: Per updated question (update 4)
Looking at the var_dump of $name_input following code should work:

$name_input = $this->input->post('name');
$passport_number_input = $this->input->post('passport_number');

$data = array();
foreach ($name_input as $idx => $name) {
    $data[] = array(
        'name' => $name_input[$idx][0],
        'passport_number' => $passport_number_input[$idx][0]
    );
};
$this->db->insert_batch('customer_info', $data);

It is further needed to access the [0] element as the POST input is passes as an array of arrays

Update 2: Seeing the problem is because the POST returns the data as a further array following code MIGHT work. I would need var_dump of POST inputs ($hi_input..) to give the exact code.

$hi_input    = $this->input->post('hi');
$hello_input = $this->input->post('hello');
$how_input   = $this->input->post('how');

$data = array();
foreach ($hi_input as $idx => $name) {
    $data[] = array(
        'hi' => $hi_input[$idx][0],
        'hello' => $hello_input[$idx][0],
        'how' => $how_input[$idx][0]
    );
};
$this->db->insert_batch('table', $data);

The following code should work as I have tested it (I do not have CodeIgniter Installed). It does not use CodeIgniter to get post data.

$hi_input    = $_POST['hi'];
$hello_input = $_POST['hello'];
$how_input   = $_POST['how'];

$data = array();
foreach ($hi_input as $idx => $name) {
    $data[] = array(
        'hi' => $hi_input[$idx][0],
        'hello' => $hello_input[$idx][0],
        'how' => $how_input[$idx][0]
    );
}; 
$this->db->insert_batch('table', $data);

Update :
You can also do this using $this->db->insert_batch();, like this :

$hi_input    = $this->input->post('hi');
$hello_input = $this->input->post('hello');
$how_input   = $this->input->post('how');

$data = array();
foreach ($hi_input as $idx => $name) {
    $data[] = array(
        'hi' => $hi_input[$idx],
        'hello' => $hello_input[$idx],
        'how' => $how_input[$idx]
    );
};
$this->db->insert_batch('table', $data);

Old answer
The CodeIgniter documentation on insert - http://codeigniter.com/user_guide/database/active_record.html#insert
states that the $data parameter is an associative array with column names as keys and data to insert as values.

So you need to call it once for each row. Thus
Try this:

$hi_input    = $this->input->post('hi');
$hello_input = $this->input->post('hello');
$how_input   = $this->input->post('how');

foreach ($hi_input as $idx => $name) {
    $data = array(
        'hi' => $hi_input[$idx],
        'hello' => $hello_input[$idx],
        'how' => $how_input[$idx]
    );
    $this->db->insert('table', $data);
};
