Php newsletter error

[Yuki H.]

I have a bit of a problem with my newsletter
here is the error I get:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/happy/public_html/newsletter/subscribe.php on line 64

Can somebody tell me my errors?

[barnamos]

I would guess it may be that you are running a query on newsletter but your database is called user_newsletter. :)

add or die(mysql_error()); onto all of your mysql_query($q) lines and see if that doesn't tell you whats up.

[Yuki H.]

That helped a bit, thank you.
But I still have errors and since I am new at php I do not know how to
correct them. (is there a such thing as a php validator?)

In sindex where it says:
$rs = "select from subscriber blah blah"
$rsCheck=mysql_query($rsQcheck);
make it say
$rsCheck=mysql_query($rsQcheck) or die (mysql_error());
and same for any mysql_query($whatever).
Its looking like your querys are returning any results. That can be because the dbs don't exist, or the syntax is bunged up or maybe permissions. Because I can't see your database structure I can't tell which. the mysql_error will tell you what the problem is.

on nindex put the same mysql_error on the insert block too. I don't use extract but once the other errors are cleaned up it should work. If not I'll rewrite that block for you to not use extract.

Its also possible you need to do the insert part of this script once to get some records in there.

Don't worry about the header errors, once the script runs clean they will probably go away.

[Yuki H.]

>......<
I think this script does not like me...

I do not know any alternative ways instead of the extract function because I am not so good with php.
But thank you for the help so far...
