Hi there,
I came up with a solution :
I created unique session variables for form data for each page and restricted only a single instance of a page to be opened at any time.
If anybody has a better solution I would like to know.
Thanks

Re: populating a dynamically geneated drop down input box
Hi there i found a potential solution
Just used this line of code that I found on the web.
var inventoryitems = <?php echo '["' . implode('", "', $inventoryitems) . '"]' ?>;
where $inventoryitems is an array - $inventoryitems = array ("value1", "value2", "value3", "value4")

Re: populating a dynamically generated drop down input box
And here is the html for the javascript in the previous posting...
<html>
<body>
<div id="container"></div>
<br>
<div>
<button id="generate">Generate</button>
</div>
</body>
</html>
I thought it would be easy enough but unfortunately not. Any help would be appreciated.

Re: handling session variables when the same page is opened
Hi there, I found some code that was useful - it used a javascript function call to open up a window. The trick that it does is if there is already an instance of that page open, then it opens the page on that page's window. I also made the session variable names different so that coupled with using...

Re: handling session variables when the same page is opened
I found out from the author of the code that it is not dependent on the filename of the page but the domain name of the url so unless i modify it, it wont suit my purposes. i.e. you cant have more than one page rendered from the same website, not the page itself.

Re: handling session variables when the same page is opened
yeah im guessing it is not as easy as just having different filenames for the web pages. what i did to stop overwriting session variables was to use different names for session variables for each page. But this means I still have to stop opening multiple instances of the same page. So i was hoping t...

Re: handling session variables when the same page is opened
Hi, yeah i am looking into code on this url that could do the trick but it isnt working out quite the way i expected. I was under the impression that if the webpage was the same name, it would stop it from opening. But this doesnt appear to be the case. I have tried opening 2 pages of different name...

Re: handling session variables when the same page is opened
Thanks for your reply. so do you think that if there is just one instance of the page allowed to be opened at any time that this will avoid the session variables being overwritten? How would i test for that? Or alternatively as you say we store the data being updated in a temporary table in mysql? B...

menu options dont appear when window is maximised
Hi there, I translated aspx pages into php pages and found that the menu options on the default page do not turn up on some browsers when the window is maximised. It works fine on browsers on my laptop regardless of whether they are normal size or maximised but only works if normal if browsing on ot...
