复选框中的PHP数组

Question

Is it possible to populate a PHP array from selected checkboxes?

The application of this is that I am building a form for registering dance students and I want them to be able to select which classes they want to register for and then submit them to a database via an array.

Also important information is that the array is inside of a PHP class.

Yes it is possible. You'd have to rename your inputs to:

<input type="checkbox" name="courses[]" value="1">
<input type="checkbox" name="courses[]" value="2">

Adding the brackets would automatically create an array on the server side given by $_POST['courses'] for example.

And to get the selected boxes:

foreach($_POST['courses'] as $course) {
    // do stuff
}
