问题
I'm trying to set up a codeigniter web app I just recently finished on a server. I wrote it locally on my own computer. However when I try to login I get these two errors.
A PHP Error was encountered
Severity: Warning
Message: mysql_real_escape_string() [function.mysql-real-escape-string]: Access denied for user 'ODBC'@'localhost' (using password: NO)
Filename: mysql/mysql_driver.php
Line Number: 319
A PHP Error was encountered
Severity: Warning
Message: mysql_real_escape_string() [function.mysql-real-escape-string]: A link to the server could not be established
Filename: mysql/mysql_driver.php
Line Number: 319
Anyone know what the problem is?
回答1:
First make sure you are connect to your db
you can modify the settings in application/config/database.php
for codeigniter you should use
$this->db->escape()
Details and samples can be found here http://ellislab.com/codeigniter/user-guide/database/queries.html

I finally found what was causing the problem. It was this line in the database config folder:
$db['mydb']['autoinit'] = FALSE;
When I changed it to :
$db['mydb']['autoinit'] = TRUE;
It worked! Thanks guys for all your advice, wouldn't have done it without you!

The answer is simple: mysql_real_escape_string() (the hint is in the name) escapes a string based on the receiving character set used by the DB connection. In order to use this, you first need to be connected to a MySQL server!
Auto-load the DB class and have it auto-connect. It'll solve your problem.
