I agree on leveraging your position to guide this thing. Here you've added
the requirement of being able to revisit the data in a year.
Why not simply have them fill out the form, put it in the database and then
use another page with queries to draw the data into a similar template and
change it as needed? Simple forms should handle this just fine, and you can
require passwords to the data.
As far as filling it out online, let them pull up the form, fill it out and
reconnect, then press submit.
Wouldn't this cover what you want?

This is exactly what I'm looking to do; but my problem remains: I don't
know what the best solution is.
The problem is clear: the users actually need an electronic copy of the
data they submit; they must revisit certain issues annually, and would
need to access the data they submitted the previous year; either for
review purposes, or to make the new submission a speedy matter of simply
changing the details that are different from last year.
It's much like a normal office scenario: each person works on Word docs
that need to be shared with others, yet needs to be editable and must be
saved etc, BUT the difference here is that the data of all the
collective sources must be entered into a central db. So the "non
technical" solution would be for the users to do the forms in "word",
then fax it to the central office, where you have a temp type the data
into the db... we can't have that now...
Any ideas?
PS, I don't think cookies are going to do this. Remember, the user needs
to be able to access and re-submit the form at any stage.

There are different issues here
If they want to save a half-completed form, you *could* save that data
server side in either a table, temporary table, or file, and have them
log-in to continue using it. I have done this many times. You could also
save the data client-side with cookies, but there's no guarantee that
cookies will work on a specific client.
If they want back-up/proof of doing it, then they can print the browser
screen as they fill it in, AND, you can give them a confirmation page which
prints all the form values back to the browser as a printable HTML page
which they can either print or save as TEXT or HTML.
Writing something that works offline for completion online later sounds like
you're trying to make the web do something it wasn't designed for. The only
solution I can think of is client-side javascript saving the form
information as a browser cookie, but there's no way I'd bother, because it
would require the user to have both javascript and cookies enabled, and I
think there's also issues with the issuing domain of the cookie.

You can create a form inside a PDF document, and it can POST the completed
data to a URL. So they could complete the form offline, print it, whatever,
then connect, and hit submit. It would open a browser window with a URL
like http://yourdomain.com/parseThePDFForm.php and then you would have your
submitted data.
Whilst not as a elegant, they COULD fill in an excel file, and upload it via
a browser.
Same with word.
I'm not sure if wither excel or word has any method of POSTing data.
With all these client-side options, there's zero hope of getting them to
correct missing fields though :)
Decide if this is something you want to achieve on the web, or offline. If
on the web, keep it basic, with perhaps a save to server option and a
printable thankyou/proof page. If offline, I think PDF forms are the best
of a bad bunch.

You could use the mail() function to automatically send an email to your
user. In the email could be an html page with the same form they'd filled
out plus some hidden input fields which would tell you that they are
updating their stored information. With this, your user gets confirmation
of what was submitted, a way to edit their initial input and a record which
they can keep on their own computer.
Hope this helps,
Hugh

I writting a php program for a small insurance company and they want to receive
uploaded digital photos.
Should I store the photos in a mysql database or in a directory on the hard drive?
If you have experience with this any advice would be appreciated.

I prefer storing them in the filesystem, and using the MySQL database to
keep track of WHERE they are (link). There of course are SOME problems with
that... mainly because the two are not joined at the hip... someone could
accidently trash the file, or the MYSQL record, without deleting the other.
Storing the image directly in MySQL has never appealed to me, because you
have to do a little more work to get the image out (sending headers, having
an image script, etc), and mainly because the size of the DB increases
dramatically... which makes backing up more difficult/time consuming.
Each to their own though :)

I have the following headers in download.php which forces a download dialog box to be
opened when a user clicks on a desired file:
header("Content-type: application/octet");
header("Content-Length: $filelength"); header("Content-Disposition: attachment;
filename=".basename($fname).";");
This works fine with IE, but Mozilla adds a '.php' extension to the filename if i
choose the save option, and asks me to choose which application to use if I want to
open the file. The files are binary.
Do I need to change the content-type header? If so, to what? If not, what do I do?
Thanks, Dara

No, that doesn't change anything with Mozilla, and as for IE the file is automatically
displayed in the browser. I actually want the Dialog Box to appear. I think Mozilla
doesn't know what to do with 'application/octet.'

The correct Content-type is "application/octet-stream". Should work with that.

hi ...
im having a little problem with mysql_query("insert into members
('$company', '$name1', '$name2', '$address1', '$address2', ''$ac1', '$ext2',
'$num1', '$ac2', '$ext2', '$num2', '$city', '$state', '$zip', '$desc',
'$flags')");
for some reason those variables are empty by the time they get into the
table...
im running mysql 3.2.3.x, php 4 used as module in apache, windows me and
apache 1.3.4xxxx the variables come from a form and then posted to a
comfirmation page where all the contents of the variables are printed in a
table before user would click the continue link at the bottum of the
page... after that the link would call a file called addtolist.php which
would add the var list to a table and return either an error message or a
success message.. i havent yet found how to have a php script load a new web
page other than include() or require() and dont know if that is making my
problem or just what it is... i will include the test file called
addtolist.php below...:
<?php
mysql_db_query("wata", "insert into members VALUES('$company', '$name1',
'$name2', '$address1', '$address2', '$city', '$state', '$zip', '$ac1',
'$ext1', '$num1', '$ac2', '$ext2', '$num2', '$desc', '$flags')");
echo "\n";
echo mysql_error();
echo <<<ENDOF_BLOCK
$post['name1']
your entry was added!!!!
go back to the main menu by clicking <a href="main.htm">here</a>.

tnx for the help

Are these variables received by handling a form submit? You should use the
$_REQUEST array if you have register_globals off:
mysql_query("insert into members
('{$_REQUEST['company']}', '{$_REQUEST['name1']}', '{$_REQUEST['name2']}',
'{$_REQUEST['address1']}', '{$_REQUEST['address2']}', '{$_REQUEST['ac1']}',
'{$_REQUEST['ext2']}', '{$_REQUEST['num1']}', '{$_REQUEST['ac2']}',
'{$_REQUEST['ext2']}', '{$_REQUEST['num2']}', '{$_REQUEST['city']}',
'{$_REQUEST['state']}', '{$_REQUEST['zip']}', '{$_REQUEST['desc']}',
'{$_REQUEST['flags']}')");
Two other 'littles' I see:
- your original statement comes with two single quotes before "$ac1", this
will break the query if it's not a message typo here.
- the "ext2" value is inserted twice
- I personally prefer to explicitly name the columns on any insert, even if
I populate all columns. If by chance your table structure will change
(using ALTER TABLE) your insert statement will break.

the right option?

The way to do it is to programmatically output the <SELECT> element.
Store the options in an array, then step through the array building up the
<SELECT> and <OPTION> tags inserting "selected" where appropriate.

Hey!
I believe there was question like this, but I was wondering if someone
could point me with useful information about passing variables to
<iframe>.
Is there some tutorials about that? Or some help files about that, ways
to do it.
Thanks!

To point out the obvious, you can pass variables to any URL by using GET:
<iframe src="page.php?var1=foo&var2=bah"></iframe>
iframes can be targeted with links just like a regular frame, using
target="frameName"
Other options would be to have variables stored in sessions, in cookies, or
via POST variables (I think).
But (to the best of my knowledge), since PHP is server-side, these pretty
much all rely on reading/acting on the variables whilst the page is being
processed and sent by the server.
I get the feeling you perhaps want to have an existing page in an existing
iframe react in relation to things happening elsewhere... correct?
I don't think it REALLY can, since once the frame's content is server-side,
it has nothing to do with PHP. You basically need to force the frame's
contents to refresh, perhaps with new variables passed in with either GET,
POST, sessions or Cookies.
Javascript can read cookies, but I don't think this is your answer at all.
You need to be more specific about what you want to achieve.

Greetings,
I'm working on a system to track homework and assignments for
teachers/students. I'm in high school, and I decided I was sick of writing
down the homework for the day, so I'm building a site that will allow
teachers to post assignments/homework for each of their classes. Students
can then go online and view it, but I digress.
I'm working on the part of the site to parse your session for student id,
check the students table for your class listing(named period1, period2,
period3, etc), and then check the classes table based on the id numbers in
your students.period1(etc) fields. I've created a function for parsing the
assignments table against your session id and such, and pulling up the
posted assignments. However this is where I hit a brick wall.
I need to pass the class_id argument to the function. I.e. class_id 1234 to
pull up all the matching assignments on class 1234. I don't know how to pass
it dynamically though, based upon the settings in your
students.user.period1.
I was thinking along the lines of using a for statement, with a nested
switch. Here's what I've rather conjured up thusfar, which I can't get to
work.
:::::::::::::::::::::::::::::CODE:::::::::::::::::::::::::::::
for($i = 0;$i < 7;$i++) {
switch ($i) {
case 0:
$class_info = mysql_query("SELECT * FROM classes WHERE $id =
".$classes_array[period0]);
$class_info_array = mysql_fetch_array($classes);
$class_id = $class_info_array[id];
display_class_assign($class_id)
:::::::::::::::::::::::::::::CODE:::::::::::::::::::::::::::::
The cases are all the same, except period0 is replaced with period1,
period2, etc. up to case 7 which is periodpaws. Classes_array refers to
this:
:::::::::::::::::::::::::::::CODE:::::::::::::::::::::::::::::
$classes = mysql_query("SELECT period1, period2, period3, period4, period5,
period6, periodpaws, period0 FROM students WHERE id = $id");
$classes_array = mysql_fetch_array($classes);
:::::::::::::::::::::::::::::CODE:::::::::::::::::::::::::::::
I can post the code for the function if I need to, but I don't think that's
where the problem lies. The way I've set it up it works fine if i do
display_class_assigns(1234) and it pulls up the fields, displays, etc
perfectly.
Thanks for your time,
Blaine von Roeder
PS: I'm sort of new to the entire PHP scene(learning as I go) so if there
are any tweaks or optimizations I can use(such as not using that unwieldy
switch with lots of nearly identical code), please let me know.

I can't figure out how to tell which button was pressed by a user when i'm
using a "button" instead of a standard "submit" form element.
This works:
<input type="submit" name="parent" value="foo">
$parent will equal "foo"
This doesn't work:
<button type="submit" name="parent" value="foo"><img
src="icon.gif"></button>
$parent will equal "<img src="icon.gif"> NOT "foo"
How do I get the value of "foo" to be returned in $parent and still use a
graphical icon instead of a standard submit button?
thanks,

The W3.org site is down at the moment, so I can't confirm this, but I'm
pretty sure...
<input type="submit" name="parent" value="foo" src="icon.gif" />
... is correct, but I've never done it :)
I think the page you want to look at is:
http://www.w3.org/TR/html401/interact/forms.html#edef-INPUT

This will only print "equal" and not "more equal".

Is there a simple way for me to programmatically know if an error has
occurred during my script? (besides from writing a custom error handler?)
I want to be able to know at the end of my script if any errors where
thrown and then show a simple message. I know that if the error is fatal
my script won't run to completion but that is ok as a fatal error in
this case should be fatal.
Is there some function like get_last_error()?
Thanks,
Jc
