"then the page gets reloaded and clears all the javascript error messages
and does the PHP validation."
That is because the form is getting submitted... make sure you js code
prevents form submit if errors are found....

Does the js function return false on the errors to block the submission?

Good Day,
I need help in in validating a form.
The for is valdated be a javascript frist then if
all the fields are filled in its valaded be PHP.
The Form starts with:
<form name="myForm" action="<?php echo $_SERVER
['PHP_SELF'];?>" method="post" onsubmit='return formValidator()' >
The “formValidator()” goes to a javascript and does display the
missing information in this case BUT then the page gets reloaded and
clears all the javascript error messages and does the PHP validation.
The PHP only runs if the fields are set by testing using ‘isset”.
Without puting on numeric lines of go can you suggest things I must
have overlooked. Silly request but there must be something I’m overl
ooking. I have simular code on other programs but this one is cas
uing me trouble.
Thanks every so much..

The "formValidator()" goes to a javascript and does display the
missing information in this case BUT then the page gets reloaded and
clears all the javascript error messages and does the PHP validation.
The PHP only runs if the fields are set by testing using 'isset".
Without puting on numeric lines of go can you suggest things I must
have overlooked. Silly request but there must be something I'm
overlooking. I have simular code on other programs but this one
is casuing me trouble.
Thanks every so much..
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.
Cheers,

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

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.
