 Posted: Wed Apr 16, 2008 8:53 pm Post subject: Database wrapper class problem |
 |
|
Hi,
I'm using Smarty in conjunction with MDB2. I'm creating a db wrapper class for MDB2, which connects to a db and then is supposed to display an error message if it can't connect.
To test the class I passed a fictitious database name via the dsn, which should have produced an error message, but it's not producing one.
Here's the class:
Code:
| Code: | class Db_conn {
var $dsn;
var $db_conn;
function set_dsn($dsn){
$this->dsn = $dsn;
}
function connect(){
$this->db_conn = &MDB2::factory($this->dsn);
if(PEAR::isError($this->db_conn)){
echo ($this->db_conn->getMessage().' - '.$this->db_conn->getUserinfo());
}
}
} |
This is how the object is used:
Code:
| Code: | $db_conn = new Db_conn();
$db_conn->set_dsn($dsn);
$db_conn->connect(); |
However, when I use the following code outside of the class, the error message appears correctly (informing me that the database doesn't exist):
Code:
| Code: | $mdb2 = &MDB2::factory($dsn);
if (PEAR::isError($mdb2)) {
echo ($mdb2->getMessage().' - '.$mdb2->getUserinfo());
} |
Can anyone see why this error isn't appearing when I place it within my wrapper class / instanciated object? e.g. something to do with error catching?
Many thanks |

No worries, don't lose any sleep, sorted it.
The answer was staring me in the face:
the var $db_conn was the same name as the class name, which is fine on Linux, but Windows got a little confused, altogether now, ahhhhhh poor little Windows.
Learn something new every day, just a shame it took 3 hours to find out. |
