Hi folks,
i have a problem with a value that it is not passed as POST variable from a
php page to another.
this is the error i have encountered :
*Notice*: Undefined index: idschema in *....\SubmitSchema.php* on line *22*
Follow the code of the main page :
-----------------------
<?php
$c = oci_connect("system", "oramanager", "//localhost/XE");
if (!$c) {
$m = oci_error();
echo $m['message'], "\n";
exit;
}
else {
print "Connesso!";
}
$s = oci_parse($c, 'select username from dba_users');
oci_execute($s);
print '<center>';
print '<h2>Seleziona lo schema desiderato</h2>';
print '<form name="SelezioneSchema" action="SubmitSchema.php" method=get>';
print '<br>';
print '<select name="selezioneSchema" id="idschema">';
while ($row = oci_fetch_array($s, OCI_NUM+OCI_RETURN_NULLS)) {
foreach ($row as $item)
print '<option value="opzione1">'.htmlentities($item).'</option>';
}
print '</select>';
print '<input type=submit value="Invia">';
print '</form>';
//print 'Valore id_schema'.$idschema;
oci_free_statement($s);
oci_close($c);
?>
-------------------------
and this is the code of the SubmitSchema php page:
---------------------------------------------
<?php
if ( isset($_POST['idschema']) ) {
echo "setted";}
else
{
echo "not setted";
}
$query = $_POST['idschema'];
print $query;
?>
-------------------------------
I cannot retrieve the value being selected by the user with the dropdown
list, do you have any idea or workarounds?Thankyou!
regards
Matt
