RE: [PHP] Silly table and php question.
Well, I guess what you can do is embed the PHP within the table cell and
call an if statement. Like this...
table
tr
td
// if the user is online, then display the online image
?php
If ($user = online) {
?
img src=online.gif
// else if the user is offline, display the offline image
?php
}
elseif ($user = offline) {
?
img src=offline.gif
// This is just some error checking
?php
} else {
echo $some_error;
?
?php
}
?
/td
/tr
/table
Try that, it's simple and short, and it works within the table cell you
would specify. Of course, you may have to alter the code and the code
structure a bit to fit your scheme. If you're new to PHP then stripping away
the comments I placed for you might help to make the code look more clear to
you. Good luck...

Subject: [PHP] Silly table and php question.
Hi all.
I know this is a silly question but i dont know how to do it so thats why i
am asking.
Be gentle towards me. Im just a stupid swede! ;-)
statement:
I have a table cell in my upper right corner.
I have a small php script which checks wheter my user is online or not. If
the user is i want to update that cell
with an gif that i made that says online.
How do i update just that cell? Is there a special function in PHP to do
that?
I know the question is silly but bare with me.

RE: [PHP] stripping white space?
I guess this is just one of those things where everyone's opinions runs in different directions, yet everyone is entitled to their own. I myself try to respect the standard because of the browser war years which made everyone uncomfortable. Now most browsers are trying to merge into a single standard (thank god). I believe the future to be XML, and I also don't think HTML will ever go away. However, I do believe that HTML will be treated more strict (hence the emergence of XHTML which is based on HTML 4.0 and XML). My suggestion to everyone is to continue using standards and try not to go astray from them, else we know the headaches us developers can face in the future.

Yeah, I know that XML requires it. And I also know that it is not a good code practice, but it perfectly works for HTML pages. Browsers compatible with the style sheets have no problems with this code (there's no connection), and if there's any XML to work on the HTML will be rewritten anyway, so there's really no reason to worry about it. Just the size gets lower and typing (escaping in PHP) is easier. I think it IS a good practice if you only practicing HTML to be outputted by PHP.

RE: [PHP] Removing quotes (was stripping white space?)
My thoughts exactly Comrade --Navid Yar -Original Message- From: Kurt Lieber [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 10, 2001 9:27 AM To: Maxim Maletsky; [EMAIL PROTECTED] Subject: [PHP] Removing quotes (was stripping white space?) Will IE 6 support this non-standard coding style? What about mozilla 1.0? Opera? Konqueror? I think the point is that standards give you a pre-defined style guide that everyone can code to and know that their applications will (or at least should) work across multiple platforms. While removing quotes will work today, it may not tomorrow or the next day. However, by adhering to standards, you have a much better chance of your code not breaking as new browsers get released. An ancillary point is the size savings that you likely get on a single page is 30-40 *bytes*. So you're saving a whopping.01 second of download time. (ok, maybe a bit more, but you get the point) As someone else pointed out, this is a holy war type of thing, so not everyone will agree. However, the points above are why I adhere to coding standards as much as possible. --kurt - Original Message - From: Maxim Maletsky [EMAIL PROTECTED] To: 'Mark Charette' [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Monday, July 09, 2001 11:18 PM Subject: RE: [PHP] stripping white space?

RE: [PHP] how to hide dbconnect file if its in publisheddirectory?
Hmmm, I was wondering about security of PHP also. Does anyone know the general issues of security within PHP documents?
