Re: [PHP] Empty form

[Steven Walker]

Ben,

I've been dealing with this problem recently. The solution I found works 
great in my case... the data processing page is the same as the form 
page.

When the page is loaded it tests for post data. If no data is available 
(ie !isset($name)), then the form will be displayed. When the user 
submits the form, it actually submits it to the same page ($PHP_SELF). 
This way, no matter how many times the user makes mistakes, your page 
will faithfully redisplay the form until they get it right. You can even 
build in special formatting, such as highlighting missing or incorrect 
fields.

When the post data is verified, the page can display the next page by 
using an include() or header() redirect, and bypass the form.

I hope this helps.

Re: [PHP] Empty form

Using header() to return will clear the entire form where all you want is
the person to fill in missing data.  Yes?

I'd use something like:

if(!isset($name) die("Use the Browser's Back Button, fill in your name and
hit the \"Submit\" Button");

if(!isset($address) die("Use the Browser's Back Button, fill in your address
and hit the \"Submit\" Button");
etc.

This way, the user fills in only the missing data.
Hope this helps.
Hugh

[PHP] Empty form

[Ben Clumeck]

I am trying to have my form redirect back to my form, if the 'name' field is
not filled in or the submit button is not pushed.  Can someone tell me what
my problem is with the script below that I have in my header:



Thanks,

[PHP] Empty form variables when uploading, Help please???

[Sandra Rascheli]

Hi everybody,

I hope someone is able to help me with this, I've been having this problem for  a 
couple of months now and I have not been able to find a solution. I have a form to 
upload a file which submits to itself, and has two submit buttons, one called 
"eliminarfoto" (deletephoto) and "salvar" (savephoto), but for some weird and 
unexplainable reason (it only happens to some users, not all of them) when they hit 
any of these two submit buttons, the form returns empty variables.

This is part of my script, has anybody had a similar problem before??? Any help would 
be greatly appreciated.

$foo = strlen($foo) ? "'$foo'" : 'NULL';
.

.
$query = "insert into bar (foo,...) values($foo,...)";

[PHP] empty form field => pgsql NULL gracefully how?

[Britton]

Having nice simple things like

INSERT INTO testtab2
VALUES ( upper('$symbol'), '$two_liner', '$href',
 '$full_desc', '$submitter_name',
 '$submitter_email', CURRENT_TIMESTAMP )

I hate to muck them up with a bunch of tests for empty vars, which then
need to be replaced with NULL and have the single quotes ommited, etc. if
there is some more graceful way?
