从表到<select> - > <option>的值

How I can insert values from database to <select> -> <option> in HTML?

Example:
I have table with ID_class and name of class. And I would like to user can choose <option> with value name of class.

<select>
   <option>VALUE FROM TABLE</option>
   ...
</select>

I work with PDO and jQuery.

It's not obvious where you're getting stuck, but here are some snippets to help out.

First of all, your select needs a name and options need a value, so that the selected value can be accessed on the server side.

<select name='chooser'>
  <option value='name-1'>...</option>
  <option value='name-2'>...</option>
</select>

On the server side, your query should look something like this using PDO:

$insertData = $con->prepare('
    INSERT INTO your_table
    VALUES(
        DEFAULT,
        :name,
    )
');
// the value of $_POST['chooser'] here is the value of the selected option (e.g. "name-2")
$insertData->bindValue('name', $_POST['chooser'], PDO::PARAM_STR);
$insertData->execute();
