Hi all,
I am having problems with a connection to a mysql database.
I am using
----
function con()
{
mysql_connect("localhost","user","pass") or die(mysql_error());
mysql_select_db("tava") or die(mysql_error());
}
----
Now, when I call the _function_ (!)
----
con() or die("no con");
----
I get the "no con" output.
When I call the mysql_connect and mysql_select directly before executing a
query, I get some DB output. But that won't work when I am using the
function...
Any ideas would be greatly appreciated.
Cheers!
Chris

I think you need to return something from the function, like true if the
connection/select worked, false if not.

I think you need to return something from the function, like true if the
connection/select worked, false if not.

You are correct.
function foo() {
// does something
}
var_dump(foo()); // returns NULL
why? because you don't explicitly return anything. If you did, that'd be
the return value. So if you did:
function bar() {
// does something
return true;
}
var_dump(bar()); // return true
Now, your script assumes a return-value:
baz() or somethingElse();
is an expression. This basically says:
if(!baz()) {
somethingElse();
}
Now, return (implicitly) null will result in (trough lazy comparison) a
false value (*null == false*, null !== false), which then triggers your
die() condition. Returning a meaningful value will get rid of that.
Other than that, choose 1 of 2 techniques:
1. error out inside the function itself (like you do now)
OR
2. error out based on the return-value of the function (like you do now
ASWELL)
don't combine 1 and 2, stick with either, but not both.
function con()
{
mysql_connect("localhost","user","pass") or die(mysql_error());
mysql_select_db("tava") or die(mysql_error());
}
con();
works. The following would work too:
function con()
{
$r = mysql_connect("localhost","user","pass");
if(!$r) {
return false;
}
$r2 = mysql_select_db("tava");
if(!$r2) {
return false;
}
return true;
}
con() or die('no conn');
would also work correctly. So, stick with either, don't mix em.

It's a bit of a long shot but are you using variables in the function
which might be out of scope?

Hi mate,
no, I am using no variables in the other function. The function goes like
con() or die("no con");
$query = "SELECT ********";
and so on
and I always get "no con"...
Cheers!

You did restart the server after making the changes?

Hi all,
Some months ago i worked with XML. And i remember that i was able to create xml
files quite easily. Now i don`t have the book i used by the time. I made many
searches in google and i don't find something interesting. So i'm wondering if
somebody can give a good link with examples. If i remeber well, i can create
axml file without writing the hole file to a string before writing the string
to the file.
Thanks a lot

Hi,
How are u doing these days?Yesterday I found a web of a large trading
company from china,which is an agent of all the well-known digital product
factories,and facing to both wholesalers,retailsalers,and personal customer
all over the world. They export all kinds of digital products and offer most
competitive and reasonable price and high quality goods for our clients,so i
think we you make a big profit if we do business with them.And they promise
they will provide the best after-sales-service.In my opinion we can make a
trial order to test that. Look forward to your early reply!
