Re: [PHP] Form validation issue
Does the js function return false on the errors to block the submission? Bastien Sent from my iPod On Dec 20, 2009, at 9:43 PM, "Ernie Kemp" wrote: Good Day, I need help in in validating a form.

Re: [PHP] SQL Queries
You should be able to do this from within the query. Try the following query: DELETE users.* FROM users LEFT JOIN notes USING(user_id) WHERE notes.note_id IS NULL Take care, Floyd On Dec 20, 2009, at 4:30 PM, דניאל דנון wrote: > Hey, Lets assume I got a table named "users". > It contains id & name. > > I have another table called "notes" - which contains id, user_id, contents > > > I want to delete all users from table "users" that don't have notes (SELECT > ...

Both at home and at work there are caching DNS on the LAN. So a DNS request may come back with a valid IP address when the WAN connection is down. I still won't be able to connect to the remote site.

Ernie: Client-side javascript can help populate fields and correct any problems a user might have, but once the form is submitted to the server, then the data is sent and evaluated server-side, hence validation. However, if the server-side evaluation fails and the page is refreshed, then all the previous values are lost -- UNLESS -- you keep them in a cookie, database, or session. I suggest using a session.
