Answer 2

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

$i = 0;
foreach ($_POST as $val) {
    $name = $_POST['name'][$i];
    $age = $_POST['age'][$i];

    mysql_query("INSERT INTO users (name, age) VALUES ('$name', '$age')");
    $i++;
  } 
}

This will solve your problem !

$education_institute_array = $_POST['education_institute'];
        $education_qualification_array = $_POST['education_qualification'];
        $education_start_date_array = $_POST['education_start_date'];
        $education_end_date_array = $_POST['education_end_date'];
        $education_note_array = $_POST['education_note'];
        for ($i = 0; $i < count($education_institute_array); $i++) {
            $education_institute = mysql_real_escape_string($education_institute_array[$i]);
            $education_qualification = mysql_real_escape_string($education_qualification_array[$i]);
            $education_start_date = mysql_real_escape_string($education_start_date_array[$i]);
            $education_end_date = mysql_real_escape_string($education_end_date_array[$i]);
            $education_note = mysql_real_escape_string($education_note_array[$i]);
            $sql_education_insert = "INSERT INTO `education` (`user_id`, `education_institute`, `education_qualification`, `education_start_date`, `education_end_date`, `education_note`) VALUES ('$user_id', '$education_institute', '$education_qualification', '$education_start_date', '$education_end_date', '$education_note')";
            $sql_result_education = mysql_query($sql_education_insert);
        }

Answer 4

A little bit easier code which works for me well.

if (isset($_POST['submit'])) {
     $i = 0;
     for ((array) $_POST as $val) {
       $sql = "INSERT INTO users (name, age) VALUES (
                   '{$_POST["name"][$i]}','{$_POST["age"][$i]}'
               );
       mysql_query($sql);
       echo (!mysql_affetced_rows()) ? "Query Wrong" : "Query Okay";
       $i++;
     } 
    }

Answer 5

You are doing a foreach on $_POST rather than on the name/age arrays. You should be doing foreach on name or age array like this:

if (
   !empty($_POST['name']) && !empty($_POST['age']) &&
   is_array($_POST['name']) && is_array($_POST['age']) &&
   count($_POST['name']) === count($_POST['age'])
) {
    $name_array = $_POST['name'];
    $age_array = $_POST['age'];
    for ($i = 0; $i < count($name_array); $i++) {

        $name = mysql_real_escape_string($name_array[$i]);
        $age = mysql_real_escape_string($age_array[$i]);

        mysql_query("INSERT INTO users (name, age) VALUES ('$name', '$age')");
    } 
}

I would also note that you are currently susceptible to SQL injection so I added the step of escaping your strings for name/age.

I would also highly suggest simply making a single bulk insert into the DB instead of an insert of each record individually (I will leave that up to you to implement). This approach is almost always preferable from a performance standpoint.

Finally, you REALLY should not be using mysql_* functions as they are deprecated. Consider changing to mysqli or PDO.

Answer 6

foreach($_POST['firstname'] as $key=>$value) {
    $firstname = $_POST['firstname'][$key];
    $lastname = $_POST['tipo'][$key];
    echo "Parte: $lastname";
    echo "<br>"; 
    echo "Tipo: $firstname";
    echo "<br>";
}
