Help me please. On the server detects an error. Here she is:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in z:\home\synape\www\testreg.php on line 27 Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in z:\home\synape\www\testreg.php on line 45 Извините, введённый вами логин или пароль неверный."

Here is half the code:

 include ("bd.php"); $ip=getenv("HTTP_X_FORWARDED_FOR"); if (empty($ip) || $ip=='unknown') { $ip=getenv("REMOTE_ADDR"); } mysql_query ("DELETE FROM oshibka WHERE UNIX_TIMESTAMP() - UNIX_TIMESTAMP(date) > 900"); $result = mysql_query("SELECT col FROM oshibka WHERE ip='$ip'",$db); $myrow = mysql_fetch_array($result); if ($myrow['col'] > 2) { exit ("Вы набрали логин или пароль неверно 3 раза. Подождите 15 минут до следующей попытки."); } $password = md5($password); $password = strrev($password); $password = $password."b3p6f"; $result = mysql_query("SELECT * FROM users WHERE login='$login' AND password='$password'",$db); $myrow = mysql_fetch_array($result); if (empty($myrow['id'])) { $select = mysql_query ("SELECT ip FROM oshibka WHERE ip='$ip'"); $tmp = mysql_fetch_row ($select); if ($ip == $tmp[0]) { $result52 = mysql_query("SELECT col FROM oshibka WHERE ip='$ip'",$db); $myrow52 = mysql_fetch_array($result52); $col = $myrow52[0] + 1; mysql_query ("UPDATE oshibka SET col=$col,date=NOW() WHERE ip='$ip'"); }

And the error in the code is here:

$myrow= mysql_fetch_array($result); and $tmp= mysql_fetch_row($select);

    Show the connection to the database. - Deonis

the $ db variable is not valid, most likely due to the fact that there was no connection to the database.

  • and what to do - Anton
  • check the connection to the database, and mysql_query () uses two parameters, the first line of the query, the second $ db, but not just the string, which can also cause this error. - FLK
  • @FLK, since when it’s impossible not to pass the query pointer? - Oleg Arkhipov
  • mysql_query ("DELETE FROM oshibka WHERE UNIX_TIMESTAMP () - UNIX_TIMESTAMP (date)> 900"); this is anton
  • @ anthon In the mysql database you created a table called oshibka? - LordySL

This script is taken from here . The script from this lesson has a lot of errors, but it will still work correctly if you bring it to mind. The author of the lesson made a huge mistake, without specifying in paragraph No. 4 what the table will be called. As follows from the code below the table name: oshibka. Perhaps this is the mistake. When you installed the server, did you really enter this particular data or are they taken from the example localhost, "user", "1234"?

    Kick in them there is the design of the code indenting, tear out the eye is called. Now I understand where people learn to make code. - ReinRaus
  • no, what you see in the code is my data, but the DB is called not oshibka, mysq is ant
