 Tedd, what about having it reset if you then go back and select the
 original option without submitting, i.e. you originally selected and
 submitted on A, then selected B, then selected A again?


 That's a good idea.

 Now I just have to figure out how to make it all-encompassing enough
 to handle one, or more, selection-control and compare current values
 with the values that were previously selected.

 Oh, the holes we dig for ourselves.  :-)

 Cheers,

 tedd

What about an onChange javascript function that checks all the boxes
that need input.  Call it whenever any of the inputs change and in the
onSubmit for the form, check it again.

I currently use onClick for the select control and that works wellenough. It's not the trigger that's the issue.

If I decide to do that, then I have to loop through all the tag ID's,get the current values, and check them against what was presented.This just requires some thinking and I'm about all thought-out forthe moment -- the end of another 12 hour day.


Thanks for your input.

Cheers,

tedd

--- Begin Message --- Hey guys sorry to interrupt but, the problem is rather obvious if you tryand put the <img src='captcha.php' /> - which is the captcha image it self -anywhere in the script you are effectively overwriting the sessionvariable - since you are initializing the form file session in the verybeginning of the form file, and then calling the captcha file which overwrites the session file, but that does not automatically update in the formfile so there you get the old value. If you make the check if the text iscorrect after the submit of the form, it should be correct. I hope I havemade myself clear enough.

Configure your browser to prompt you for cookies.

That will make sure you are doing the session bit the way you think
you are.

Then add some error_log statements when you set or read the secret word.

You'll soon figure out exactly how/why your session has the OLD secret
word in it.

At least I hope it is simple...
I am trying to get an HTML menu link to set a variable's value. Forexample, when a user clicks the "Home" button on my page it would cause$page = "home"; or clicking the "About Us" button will set $page="about_us";etc.
I think this should be fairly simple but being completely new to php I justcannot seem to get it right.
Any help would be greatly appreciate.

Thank you in advance.
Christopher,
Rather then criticizing you, I would like to point you in the direction that you describe in yourresponses to the others that are.
So, it sounds to me like you do not want to reload/change pages just to change the content of thecurrent page.
With PHP alone you cannot load new content without reloading the entire page, or involving one ofthe other methods listed below.
I would say that you have two avenues to get this done.

The first using a meld of AJAX & PHP
http://nodstrum.com/2007/02/27/ajaxcontentload/
http://www.dhtmlgoodies.com/scripts/ajax-dynamic-articles/ajax-dynamic-articles.html
http://www.dhtmlgoodies.com/scripts/ajax-dynamic-content/ajax-dynamic-content.html

The second is with Javascript and/or CSS

Hope these help.

You may or may not find this worth reading:
http://richardlynch.blogspot.com/2007/07/php-in-html.html

Bottom line is that what you are trying to do can't be done in PHP.

You'll have to resort to Javascript and DIV tags with display: none;
switching to display: block;

This is absolutely not true.   You can make the button call a PHP script
with AJAX and just update the textbox.

--- Begin Message --- Dunno if it's a best practice, but I store all the translations in thedb for easy manipulation and extraction to a file for others totranslate. That obviously involves both import and export utilities.
At work we to the translation in real time thru a render page thatcombined the data for the form as well as the labels and buttons.Personally I disagree with this approach and feel that caching out thepage to either HTML or XML is quicker and cleaner. But that's just me.
A number of pup apps take the approach of storing the labeltranslations in variables inside language folders ( phpmyadmin hasthis ). That is also not a bad approach but is slightly slower and Ican't help but feeling that serving up a static page created by codeis a better solution. It will be heavier on the management side, butmy experience is that this mgmt activity drops off quickly after thefirst week or two of that form being in production.

The issues arise once I start looking at PHP and Javascript code. Iuse
JS for client side input (pre-)validation and increased usability, and
error messages and such will obviously need to be language-sensitive.
The same goes for the PHP code.

With PHP, I've got gettext() for this sort of job, with javascript and
some DHTML, I don't seem to have many options.

One of my key concerns is - for the translation, I need to be able to
wrap everything up and ship it off to a translator, perhaps via elance
or similar.

Does anyone have any best practice suggestions or comments in general?

I can't help with the bits you are asking about, but I can give this
advice:

Don't rely solely on the Apache/browser content-negotiation, please.

This one time...

I was in Paris.

I was at an Internet Cafe.

I couldn't change browser settings.

Some sites that I knew were available in English showed me only
French, and no way to change it.

Despite my using a computer with a French keyboard, my French language
skills remained somewhere around the "Bonjour. Parlez-vous Englias?"
level.

Don't worry, the site already has a user-override option.

PHP/MySQL and the various functionality such as @var are all
per-connection expressly so that you CAN do this type of stuff.

I'd be pretty shocked if you had any problems.

This extension does not have to be installed. If your server is running
php5, then this extension is installed

I don't know about the PHP mysql_query(), but the MySQL C API works fine
with multiple queries, it just has to be specifically enabled - the
default is one query per call. 
However, it looks like the multiple query option is not supported by
PHP: 

http://php.net/manual/en/mysqli.real-connect.php

"For security reasons the MULTI_STATEMENT flag is not supported in PHP.
If you want to execute multiple queries use the mysqli_multi_query()
function."

Hi Ashley,
yes this is the right answer. The "Problem" is not a PHP Question buta programming question. To be clear: i think, the "Problem" can yousolve, if you get two or tree books or tutorials about the programminglanguage. You should *try* to solve the problem self and then to posta question in a list or forum. I think this is the "normal" way.
To the code i think this is very bad php code. You will get more XXSand other exploits with this code. Please tell me what is your siteand i show you

Carlos:
Whoa dude -- this list IS for people to ask questions and from what theOP asked it WAS a php question.
I totally agree with Ashley and your response is not common for this list.
As to the OP's code being "bad" or whatever, he is asking for help. Ifyou want to show him where his code is "bad", then be my guest -- but totell him to go buy a book and come back to this list after he has readsit is not something you can dictate -- you have no control over this list.
I suggest -- if you want to help, then do so. If not, then you go read abook.
