Save data passed to a PHP script via AJAX to a database

Question

I have an array:

var arr = [{"title": "lorem", "desc": "ipsum"}, ...];

that I try to save to a database via AJAX:

$.post("sample.php", {arr: arr}, function(data) { ... });

with the following code:

$data = $_POST['arr']
$values = array();

foreach($data as $value)
{
    $values[] = '('. $value['title'] .', '. $value['desc'] .')';
}

$sql = "INSERT INTO locations (title, desc)
        VALUES " . implode( ',', $values );

It gives me the following error:

Invalid argument supplied for foreach()

I am not really a PHP dev, so I don't understant what goes wrong. Any ideas?

Answer 1

You should perform the insert for each value
and you should check for the post content

if isset($_POST['arr']) {


  foreach($data as $value)
  {
       $sql = "INSERT INTO locations (title, desc)
          VALUES ( " . $value['title'] . ", " .$value['desc']  . " );"

      // then exec you insert query  -- depending by the db drivvers you are using 


  }
}
