I have a problem with IE7. It has a tendency to cache output
produced by PHP. It occurs in a few ways:
* I make a minor change to a php program, but you can't see it in
IE7, but can in FF. CTRL-Refresh does not make it work.
* I modify data using a form in IE7. When I click on a link to
return to the form the old data is still there, but if I hit
CTRL-Refresh the new values are there.
I have set up some caching to try to fix the second issue, but
I'm not sure if I've chosen the right header lines:
$now = time ();
$prety_lmtime = gmdate ('D, d M Y H:i:s', $now). ' GMT';
$prety_emtime = gmdate ('D, d M Y H:i:s', $now + $interval). '
GMT';
// Backwards Compatibility
header (Last Modified: $prety_lmtime);
header (Expires: $prety_emtime);
// HTTP/1.1 Support
header (Cache-Control: private, max-age=$interval,s-maxage=0);
I got this code from a book. I don't want to prevent caching
completely because I want to be able to go back to the form when
there is an error in validation of fields before entering it into
the db. But I do want to be able to see the new data after it is
entered in the db.

Sounds like you need attach the data somehow when hitting that
return link. Maybe an array
$newData = array();//fill this array with the new values
On your form page, set up a
if(isset($newData)){
//fill form fields
}
I did notice that on your header, you did not have no-cache.
header (Cache-Control: private, no-cache, max-age=$interval,s-
maxage=0);
Actually, I should have looked at which caching code I was using
for the second problem. This is the code:
header (Expires: 0);
header (pragma: no-cache);
// HTTP/1.1 Support
header (Cache-Control: no-cache,no-store,max-
age=0,s-maxage=0, must-revalidate);
About storing the values, I really would rather the browser keep
track of form input if I can. It could get confusing trying to
store temporary information, especially since the form is being
used to modify a client profile as well as create a new password
for the first time in the application (not my choice - I'd rather
do passwords first and then allow them to modify info).
Charlene
Are you using sessions? I would store it in a session variable. That
shouldn't make things too confusing.
Also, I would make sure the form page header has the no-cache in it,
since that is the page you dont want caching.
Or call on that form page with the time attached to the end of the
link url like what what suggested by Bastien.
This will make sure that page doesn't cache. Then set up your session
variables to store the form results.
Then use the isset condition on the form page to apply the new values
if they are present.

I am searching for a way to show the user similar records from the mysql
database. A functionality like this could also be of interest to you.
Does anybody know if this is there is a standard functionality to do
this, or a good way on retrieving this with the help of PHP?
There is the LIKE clause in the SELECT statement, or, better still,
MySQL's full text searching capabilities.
Teus.

I have some code that makes suggestions on items that one might be interested
in based on what they are buying or did buy in the past using PHP.
Is this what your interested in?
Hi David,
I did manage to create a function that provides datasets that are
similar

Hi David, I did manage to create a function that provides datasets that are similar based on the title. My page is a site similar to craigslist, so I don't know if your code would make sense. It would be interesting though to show items that have been visited by other people after the viewed a particular classified. Could your code be adapted to serve that?

[PHP] PHP GD - Create a flag
Hi, i've just started using GD libraries. My purpose is to create something like a flag. So that i have a 600*600 px background image, and a 1*1 px image for each colour I need. Ok now let's say i want to colour a third of the background image. I can use this code: imagecopymerge($base, $img1, 0, 0, 0, 0, 200, 600, 85); It will simply make red first 200 px (on x axys) of the bg image. And this work. Now the problem is: how can i add another colour on pixels from 201 (201 right? not 200?) to 400? Thankyou -- -- AnotherNetFellow Email: anothernetfel...@gmail.com
[PHP] dynamically generating and retrieving page data using flat files
Hello, I've got a project that i have to reference information stored on one page from another. This page I won't be visiting first, and at the moment i'd prefer to use flat php files, but should that prove to hard i'll transition to a mysql database. I'm looking for simplicity and maintainability. I've got a page of individuals, their names, positions, and a brief summary of them. On the main page I want to put their names and positions in an ordered list, pulling that information from the second page. The idea is whenever the second page is updated the main page will automatically update. Suggestions welcome. Thanks. Dave. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Just a wild stab, but maybe hidden form fields and javascript pr php?
