finally found the problem... wrong names for string and this is what now
verifies correctly....
if (strlen($_POST["titleIN"]) == 0 ) {
$obligatoryFieldNotPresent = 1;
}
elseif (strlen($_POST["first_nameIN"]) == 0 ) {
$obligatoryFieldNotPresent = 1;
}
elseif (strlen($_POST["publisherIN"]) == 0 ) {
$obligatoryFieldNotPresent = 1;
}
elseif (strlen($_POST["copyrightIN"]) == "" ) {
$obligatoryFieldNotPresent = 1;
}
elseif (strlen($_POST["ISBNIN"]) == 0 ) {
$obligatoryFieldNotPresent = 1;
}
elseif (strlen($_POST["languageIN"]) == 0 ) {
$obligatoryFieldNotPresent = 1;
}
elseif (!empty($_POST['categoriesIN'])) {
$obligatoryFieldNotPresent = 0;
I'd suggest something slightly different.
$errors = array();
if (empty($_POST['title'])) {
$errors[] = 'title';
}
if (empty($_POST['first_nameIN'])) {
$errors[] = 'first_nameIN';
}
...
# If we found any errors, show a message!
if (!empty($errors)) {
echo "You forgot to fill in these fields:<br/>";
echo implode(',', $errors) . "<br/>";
}
So your user knows what they missed.
