[PHP] Unable to send variables to MySQL table
Hi folks... a bit of a newbie question I'm afraid...
I've written this script shown below. It gets its variables from a form, and
then it (supposedly!) writes these values into a MySQL table ('invoices').
The script executes with no errors, but when I check the table, the table is
still empty. I can manually insert the data directly into the table, and when I
echo the variables in the script, the values are displayed whe I run it, but
for reasons unknown, the values are not written to the table.
Any ideas? The code is below.
Many thanks.

On the surface it looks fine, so I would echo out your query and then
paste it into MySQL (phpmyamin, SQLyog, etc) and check it works!
Or you could capture the result of the query and check for an error.
If there isn't one, it's probably a table design issue.
Cheers,
Rich

Re: [PHP] Unable to send variables to MySQL table
print $add_to_db;
should print out the entire insert line and you can just double check
that your values are full, otherwise like Jay said I would check and
make sure the user you have in your connect string can write to the
db.

RE: [PHP] Unable to send variables to MySQL table
snippity snip Any ideas? The code is below. snip snip mysql_query($add_to_db); Hi Stewart. Your query is failing for some reason (as others here have mentioned). I would change the above line to read: mysql_query($add_to_db) or die(mysql_error().br$add_to_db); This will make the script die, and will print the mysql error and the SQL statement that caused it.

Re: [PHP] Unable to send variables to MySQL table
snip print $add_to_db; /snip Thanks for all your replies! I didn't expect to get one so quick, so thanks! After I did the above, I pasted the output into MySQL. Guess what? It didn't work! I was only sending values for $item1_desc and $item1_cost. Because I was not sending values for the other columns, I was getting an error message saying the data was truncated for the empty variables. Now I need to figure out how to send empty values... would NULL do the job? Thanks again! Stewart -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Unable to send variables to MySQL table
I code all my apps to look for an empty variable and dump and empty set into it. That way when I code the rest of the information into the database, the files are cleaner and I don't have to worry about users and bad sets. $var = ''; Robert - Original Message - From: Stewart Priest [EMAIL PROTECTED] Date: Wednesday, November 9, 2005 2:43 pm Subject: Re: [PHP] Unable to send variables to MySQL table snip print $add_to_db; /snip Thanks for all your replies!
