Create a php page with to display an html form using the post method and submitting to the same page
Include the following fields:
album id (text)
artist name (text)
album name (text)
price (text)
media type (radio buttons)
| Value | Label |
| 1 | MPEG audio file |
| 2 | Protected AAC audio file |
| 3 | Protected MPEG-4 video file |
| 4 | Purchased AAC audio file |
| 5 | AAC audio file |
playlist (checkboxes- create at least 5 playlist names of your choice)
genre (drop down list)
| Value | Label |
| 1 | Rock |
| 2 | Jazz |
| 3 | Metal |
| 4 | Alternative and Punk |
| 5 | Jazz |
| 6 | Blues |
| 7 | Latin |
| 8 | Reggae |
| 9 | Pop |
| 10 | Soundtrack |
tracks
submit
Check to see if the form has been submitted. If not, just display the form.
If the form has been submitted, validate the form as follows:
album id: required
artist: required
album name: required
price: required, numeric
media type: required
playlist: at least 1 required
genre: required
tracks: required, numeric, minimum 1, maximum 50.
If the data is valid, transfer to a second php page and pass the album id, artist name and album name
The second page should display the message: album-id album-name by artist added (i.e. BT101 Help! by The Beatles added).
If the data is not valid, redisplay the form with the user entered values and appropriate error messages.
I wrote the answer, but is not correct .my problems are:
( You did not add the validation for tracks to be numeric and between 1 and 50, -5 points. The mediatypes are not sticky because you need to put the word checked inside the tag (before the closing >) not as part of the text. -5 points. Same for the genre (drop down list), you need to put selected inside the option tag. -5 points. When the data is valid you should transfer to another page using header("Location:...) with the values in the querystring to display the album id, name and artist. -10 points. )
if (isset($_POST['submit'])) {
$valid = true;
$albumid = htmlspecialchars($_POST['albumid']);
if (empty($albumid)) {
echo "
Please enter your Album Id.
";$valid = false;
}
$artistname = htmlspecialchars($_POST['artistname']);
if (empty($artistname)) {
echo "
Please enter your artist name.
";$valid = false;
}
$albumname = htmlspecialchars($_POST['albumname']);
if (empty($albumname)) {
echo "
Please enter your album name
";$valid = false;
}
$price = htmlspecialchars($_POST['price']);
if (!is_numeric($price)) {
echo "
Price must be numeric
";$valid = false;
}
if (isset($_POST['mediatypes'])) {
$mediatypes = $_POST['mediatypes'];
} else {
echo "
Please select a Media type.
";$valid = false;
$mediatypes[0]="";
}
$genre = $_POST['genre'];
if ($genre=="") {
echo "
Please select a genre.
";$valid = false;
}
$tracks = $_POST['tracks'];
if (empty($tracks)) {
echo "
Please enter your tracks.
";if(strlen($_POST['tracks'])< 1 )
echo "
$valid = false;
}
if ($valid) {
echo "
You entered the following information.
";echo " Album id: $albumid";
echo " Artist name: $artistname";
echo " Album name: $albumname";
echo " Price: $price";
echo " Mediatype : $mediatypes[0]";
echo " genre: $genre";
echo " Tracks: $tracks";
}
if ($valid) {
header("Location: form.php?albumid=$albumid&artistname=$artistname&albumname=$$albumname&price=$price&mediatype=$mediatype&genre=$genre&tracks=$tracks");
exit();
}
} else {
$albumid="";

$albumname="";
$price="";
$mediatypes[0]="";
