an approach:
$search = $_POST['author'];
if (!empty($_POST['author'])) {
$sql="SELECT (the relevant field names) FROM journal WHERE author LIKE
'%$search%' ORDER BY idart";
// and your mysql and output stuff here
}
else {
echo "<p>Please give the name of a possible author</p>";
}
BTW you might want to save yourself some grief down the road by reading up
about sql injection and filtering the post accordingly.
also you should use single quotes around col tags $_POST['author'] so php
doesn't try to interpret them as constants initially.
