I have a PHP script that queries a DB to get a list of image names. Then it
processes each name and generate thumbnails and what not. What I want to do
is have a page called (through the browser) which updates as the PHP process
in the background is working. So when you first pull up the page it will
say 'There are x images to process' and then dynamically update the page
with a progress status. In its crudest form it should say something like
'Processing 1 of 5 images .' When that image is done, it should update the
page with 2 of 5 . etc., etc. Ideally without refreshing the page each
time.
Is this where I need to figure out Ajax and incorporate it with PHP?

The only way to do it with PHP alone would be to control the output
buffering and I've found that to be inconsistant in quality and
predictability with different browsers even web servers. I'm sure
there's an art to getting that all working well with various technologies
that are involved in the script -> client caching and processing, but why
mess with iffy when you can use a proven technology like AJAX.
Get familiar with jQuery (or one of the other big JS libraries, but jQuery
is my choice hands-down) and you'll probably find it's pretty easy.

Hrm, been looking at it for a while now and I can feel a headache coming up.
I think I need to have one PHP script that does the processing, and another
that the user pulls up in their browser. That one "pings" the processor
every so often to get updated data. Yes?
Am I way off here?

Slightly. PHP code runs on the server, so in the browser, it won't
"ping" the server.
Yes, you should have a PHP script on the server to do the processing,
(call it, say, "process.php") and one which paints the basic screen for
the browser (call it "page.php" or somesuch). But the connection between
these should be AJAX code in the page.php script. That will most likely
be Javascript in the page.php script which will "ping" the process.php
script for whatever contents you want.
The Javascript to do this is beyond the scope of this list (it's a PHP
list, after all). The "process" script doesn't have to be PHP. It could
be any language you prefer, as long as you can get it to return JSON or
XML to page.php, so that the Javascript in the page.php script can
interpret it.

Exactly.

Ash,
Nice call. .htaccess was not being processed at all which led me to a
cname configuration error for the sub domain.
Thanks!.

I have several virtual hosts on a dedicated server.
In a IFmodule mod_php5c container in an httpd.conf include file I have
the following to create a unique include path for each virtual host:
IfModule mod_php5.c>
php_value include_path ".:/home/virtual/site#/path/to/include"
php_admin_flag safe_mode off
</IfModule>
For one of the virtual hosts I've set up a dev site in a subdomain at
dev.site#.com for development.
In the root directory of this development site I have an .htacces file
to create another unique include_path solely for this development subdomain.
php_value include_path ".:/home/virtual/site#/path/to/dev/includes"
Also in the httpd.conf I have
<Directory /home/virtual/site#/path/to/dev/root/>
Allow from all
AllowOverride All
Order allow,deny
</Directory>
The configuration is CentOS 5.3, Apache/2.2.3, PHP 5.1.6
I recently upgraded the OS from FC6 and the PHP version and I have not
been able to get the include_path to change for this dev.subdomain.
Even after restarting apache it PHPinfo tells me it is reading the
server php.ini and the virtual host include path for the httpd.conf but
it is ignoring the .htaccess file.
I've even tried putting the php.ini with specific settings in the
/home/virtual/site#/root directory to no avail.
Any ideas how to make this work or even a better set up?
Thanks in advance.
Are you able to determine if you can set any attributes with the
.htaccess file? Is it possible the .htaccess isn't being processed at all?
I'm not sure why the virtual server settings are being ignored in the
httpd.conf file though. Have you checked any other .conf files in that
directory to see that they are not being set there? As far as I can
remember, the .conf files in that directory are executed in
alphabetical order, so a different file might be overriding your settings?
Thanks,
Ash

Hello List,
I am new here, and I am hoping this will be a quick and easy for
someone to help me with.
I am trying to create an upload form that lets a user upload a
product photo to the server.
In the process of this upload, I want to take the file they are
uploading and create two images to put on the server.
Both are specific sizes. A large image and a thumbnail.
I then want to throw away the file they uploaded.
My question is what is the proper way to do the uploading/resizing/
destroying?
I have been toying with imagecopyresize, but it never works.
I think I just have parameters out of order or something.
Also, I would like to put a copyright on the side.
I have been able to use imagestringup to do that,
but it covers the image I'm placing it on with
a transparent background and deletes the image.
How do you duplicate an image with transparency?
Or keep the transparency an image already has?
Most grateful for any help, pointers, tuts.
Best,
Karl DeSaulniers

Put it in the header:
header("Cache-Control: no-cache, must-revalidate");
Remember headers must be the first output you do, read more here.

Thanks Nadim. I think I got my script to work finally, but if it
proves to be a no-go.
I will definately take a look. Thanks for sharing.

Hello Chris,
Here's a link: http://pages.intnet.mu/nadim/php/image.upload.txt
The code is minimal. Things I would like to add:
- resize transparent gifs
- resize animated gifs
Time doesn't permit me, unfortunately :-(
