Answer 1

使用这样的方法：

$sql = "Insert into staff(client_name,address) VALUES ('$client_name $address','$address')";

Answer 2

Simply concatenate your $_POST['name'] with $_POST['address'] in $client_name before inserting to database. Like this :

     $client_name = $_POST['name'] .' '. $_POST['address'];
     $address = $_POST['address'];
     $sql = "Insert into staff(client_name,address) VALUES ('$client_name','$address')";
     $this->db->query($sql);

Answer 3

 $client_name = $_POST['name'];
 $address = $_POST['address'];
 $name = $client_name .' '. $address;
 $sql = "Insert into staff(client_name,address) VALUES ('$name','$address')";
 $this->db->query($sql);

Answer 4

try this

$name = $_POST['name'];
$address = $_POST['address'];
$client_name = $name.' | '.$address;
$sql = "Insert into staff(client_name,address) VALUES   ('$client_name','$address')";
$this->db->query($sql);

Use json_encode to encode the content and then store it in database field and when you retrieve the value then use json_decode

$form_data_json = json_encode( $_POST );
// store $form_data_json in database.

// When you want to get stored data, just fetch it from db. let it be stored in $fetch 
$original_post_array = json_decode( $fetch, true );
