$sidemenus = mysql_fetch_object($results);
?>on View Page:

<?php echo $sidemenu->mname."<br />";?>
<?php endforeach; ?>Error is:
Notice: Trying to get property of non-object in C:\wamp\www\phone\pages\init.php on line 22
Can you fix it? I don’t have any idea what happened.
解决如下：
Check the manual for mysql_fetch_object(). It returns an object, not an array of objects.
I’m guessing you want something like this
$results = mysql_query("SELECT * FROM sidemenu WHERE `menu_id`='".$menu."' ORDER BY `id` ASC LIMIT 1", $con);$sidemenus = array();
while ($sidemenu = mysql_fetch_object($results)) {
$sidemenus[] = $sidemenu;
}Might I suggest you have a look at PDO. PDOStatement::fetchAll(PDO::FETCH_OBJ) does what you assumed mysql_fetch_object() to do
