Re: [PHP-DB] mysql_error function

The strange thing is, that it works fine if You use just one connection. In this case, mysql_error() function can takes error message from the mysql_connect() function... However, if you don't supply a resource idintifier it will asume the last opened link, hence your problem on the second connection failure. When using more than one link, you should specify the link resource for mysql_error(), which is difficult for the mysql_connect() function, obviously. I'm not sure if using the returned FALSE value would work, as I've never had a problem with additional connections. YES, this is the problem. Since $dblink2 = mysql_connect() is getting false (so no resource object), so $dblink is not correct parameter for mysql_error() function and it works same way as there is no parameter. OK, so mysql_error is not usable for me in this case. Is in PHP any other way how to get error-message from connect function? Isn't in PHP any other function, that can be used similiar? All of this is clearly decribed on the manual page. Niel -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

To the best of my knowledge, there is no work around for this situation. Even the 'Improved' MySQL Extension suffers this same limitation, so no improvement there. You can of course still determine failure, but not directly the cause. The only ways I can think of to begin identifying the error would be to look up supplied username/password with the MySQL permissions db to verify their authenticity, or to close the first connection and retry the second after so it is the only connection.

Re: [PHP-DB] mysql_error function
Hi The error message for second connection request is not given back to the PHP. Or as I suppose, mysql_error takes last error message from last used ESTABLISHED connection (it means from $link1) and since in this connection was everything ok, it puts empty string as a result of mysql_error function. This is incorrect. mysql_error() retreives the error message from the last mysql function (excluding itself or mysql_errno) executed, not the last connection.
