Done with 4A
Interesting to see arrays passed between pages in a similar way as normal variables. I would have thought that the following would be correct:
OR
but NO, it should be:
Seems a bit strange.

Language: PHP$choice = $_POST[';choice[]';]; // Not correct!
OR

but NO, it should be:
Language: PHP$choice = $_POST[';choice';]; // This works!
Seems a bit strange.

Done.
I replaced the code for the selection boxes with php.
<?php
$bookcats = array('Fiction', 'Non-Fiction', 'Theatre', 'Computing', 'Science'
;
sort($bookcats); //optional - sorts the categories alphabetically
foreach ($bookcats as $b) {
echo '<input name="choice[]" type="checkbox" value="'.$b.'">'.$b.'<br>';
}
?>
This allows you to ad/remove book categories easily.

Please help. This is my code for thankyou.php:
<?php
$title = "Thank-you";
include("header.php";
echo "Thanks for responding to this survey $firstname $lastname.";
echo "<br><br>";
echo "<b>These are your favorite book categories:</b>";
echo "<br><br>";
foreach ($choice as $catergory){
echo "$category <br>\n";
}
include("footer.php";
?>
I get the follwing error:
Warning: Invalid argument supplied for foreach() in C:\Program Files\xampp\htdocs\StudentPHP\thankyou.php on line 9

foreach ($choice as $catergory){

Well, the answer lies in the 1st message here above. You are to first catch the variables on the thankyou page, as explained in messages 1 and 6 and in the previous topics. You did not....!
Therefore, since you did not catch them, the argument is invalid since $choice does not exist.
I also notice a typo in the foreach statement. Now I'm not posting the complete code here, since then you won't be learning
