I need to be able to add to my $questions array, but there is no dynamics in the code, so when I add something I have to create a if sentence and a new input field for each question to store the data (the teacher demands storing in hidden type). Does anyone know a good tip of how I can get it more efficient?
<?php
date_default_timezone_set('Europe/Oslo');
$questions = array(
array(
'text' => 'Whats your name?',
'type' => 'text',
'name' => 'svar1'
),
array(
'text' => 'Do you live in Oslo?',
'type' => 'checkbox',
'name' => 'checkbox'
),
array(
'text' => 'How old are you?',
'type' => 'text',
'name' => 'svar3'
),
array(
'text' => 'Do you have friends?',
'type' => 'text',
'name' => 'svar4'
),
array(
'text' => 'Do you like going to the movies?',
'type' => 'text',
'name' => 'svar5'
)
);
$step = isset($_POST['step']) ? $_POST['step'] : 0;
if (isset($_POST['prev'])) {
$step --;
}
if (isset($_POST['svar1'])) {
$step++;
}
echo "<p><a href='/webutvikling/oblig2.php?reset=true'>Start på nytt</a></p>\n";
?>
