I want to get the category and the order variables from a HTML code and use
them in the SELECT query. I want something like this: SELECT * FROM nepal ORDER BY $category $order
.
HTML code:
<!DOCTYPE html>
<html>`asdasdasdasd`
<head>
</head>
<body>
<form action="interpret.php" method="get">
Categorie
<select name="categorie">
<option value="DECEDATI">Decedati</option>
<option value="RANITI">Raniti</option>
<option value="DISPARUTI">Disparuti</option>
<option value="CLADIRI_DISTRUSE">Cladiri distruse</option>
<option value="DURATA">Durata</option>

<option value="ADANCIME">Adancime</option>
<option value="PAGUBE">Pagube</option>

<option value="ASC">Crescator</option>
<option value="DESC">Descrescator</option>
</select>
<input type="submit"></input>
</form>
</body>
</html>
PHP code:
<?php
$conn = oci_connect('student', 'STUDENT', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
// Prepare the statement
$stid = oci_parse($conn, 'SELECT * FROM nepal ORDER BY $_GET['categorie'] $_GET['ordine'] ');
if (!$stid) {
$e = oci_error($conn);
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
// Perform the logic of the query
$r = oci_execute($stid);
if (!$r) {
$e = oci_error($stid);
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
// Fetch the results of the query
print "<table border='1'>\n";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
print "<tr>\n";
foreach ($row as $item) {
print " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>\n";
}
print "</tr>\n";
}
print "</table>\n";
oci_free_statement($stid);
oci_close($conn);
?>
