工作,我一直在使用這個類:PHP MySQL數據庫類不插入
<?
class DbConnector {
var $theQuery;
var $link;
function DbConnector() {
$host = 'localhost';
$db = 'my_db';
$user = 'root';
$pass = 'password';
// connect to the db
$this->link = mysql_connect($host, $user, $pass);
mysql_select_db($db);
register_shutdown_function(array(&$this, 'close'));
}
function find($query) {
$ret = mysql_query($query, $this->link);
if (mysql_num_rows($ret) == 0)
return array();
$retArray = array();
while ($row = mysql_fetch_array($ret))
$retArray[] = $row;
return $retArray;
}
function insert($query) {
$ret = mysql_query($query, $this->link);
if (mysql_affected_rows() < 1)
return false;
return true;
}
function query($query) {
$this->theQuery = $query;
return mysql_query($query, $this->link);
}
// get some results
function fetchArray($result) {
return mysql_fetch_array($result);
}
function close() {
mysql_close($this->link);
}
function exists($query) {
$ret = mysql_query($query, $this->link);
if (mysql_num_rows($ret) == 0)
return false;
}
function last_id($query) {
return mysql_insert_id($query);
}
}
?>
其中我使用了大量的查詢和它的正常工作,但我想用這個來插入查詢:
global $db;
$query = $db->insert("INSERT INTO `submissions` (
`id` ,
`quote` ,
`filename` ,
`date_added` ,
`uploaded_ip`
)
VALUES (
NULL , '{$quote}', '{$filename}', NOW(), '{$_SERVER['REMOTE_ADDR']}')
");
而且它給我這個錯誤:
Not Found
The requested URL /horh_new/id/<br /><b>Fatal error</b>: Call to a member function insert() on a non-object in <b>/Applications/MAMP/htdocs/horh_new/addit.php</b> on line <b>52</b><br /> was not found on this server.
雖然當我不使用上面這個類,並用此代替:
$con = mysql_connect("localhost","root","password");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
mysql_query("INSERT INTO `submissions` (
`id` ,
`quote` ,
`filename` ,
`date_added` ,
`uploaded_ip`
)
VALUES (
NULL , '{$quote}', '{$filename}', NOW(), '{$_SERVER['REMOTE_ADDR']}')
");
echo mysql_insert_id();
mysql_close($con);
它工作正常。任何人都可以告訴我我班有什麼問題嗎?我真的很感激它。
那麼從那個錯誤我會說$ db不是你所期望的。轉儲出來,你看到了什麼? – martynthewolf 2011-05-23 08:39:37
您的$ db變量在您遇到該錯誤的位置未被實例化。 – Repox 2011-05-23 08:40:17
