php - 保存在下拉列表的数据库值中

Question

我正在制作一个下拉列表，我希望当用户选择一个值时，保存到数据库。

这是我的代码:

$query = mysql_query("SELECT name FROM store_locator_bundes");
echo '<select name="bundesland-dropdown">';
while ($row = mysql_fetch_array($query)) {
    echo '<option value="'.$row['name'].'">'.$row['name'].'</option>';
}
echo '</select>';

还有条件

if($_POST[$criteria['submit']['name']]) {
    // here I am lost, I have to insert the values of the dropdown to store_locator and the field bundes_id
}

感谢您的帮助；)

Answer 1

你想要

$_POST['bundesland-dropdown']; // You want the <select> not the <options>'s name

然后插入:

if (isset($_POST['bundesland-dropdown'])){
    //mysqli/PDO/whatever database method of insertion you want here
}
