browser detection

[dreamingdigital]

Can Miva do web browser detection? It would be helpful. If not, would Toolkit be able to access something that could?

Re: browser detection

That requires client side scripting, ie javascript.

Re: browser detection

PHP can. example:

$navigator_user_agent = (isset($_SERVER['HTTP_USER_AGENT'])) ? strtolower($_SERVER['HTTP_USER_AGENT']) : '';
$safari = (stristr($navigator_user_agent, "safari")>-1) ? 1 : 0;
$ns6 = (stristr($navigator_user_agent, "netscape6")>-1) ? 1 : 0;
$ie5 = (stristr($navigator_user_agent, "msie")>-1) ? 1 : 0;
$mac = (stristr($navigator_user_agent, "mac")>-1) ? 1 : 0;
$windows = (stristr($navigator_user_agent, "windows")>-1) ? 1 : 0;
$ns7 = ((stristr($navigator_user_agent, "gecko")>-1)  &&  (!$safari)) ? 1 : 0;
$ns4 = ((stristr($navigator_user_agent, "mozilla/4")>-1) && (!$ie5)) ? 1 : 0; 

So why can't Miva?

I wonder if it's possible to call a PHP script using toolkit and have the PHP script it return the $_SERVER['HTTP_USER_AGENT'] variable string then use Miva if/else with more toolkit to assign variables

Re: browser detection

there is a server variable 's.http_user_agent' that reports the same information. Shouldn't you be able to use IF 'xxxx' CIN s.http_user_agent' ? (Use it in mivascript often).

Re: browser detection

I've never seen s.http_user_agent in any Latu storehelper vars before. I'll give it a whirl tomorrow. I'm feeling doubtful though because it's in mivascript but I've never seen the SMT version.

Re: browser detection

I tried this out recently, but it didn't work for me. (perhaps I was doing something wrong)

However, it seemed to work fine using Bill's WCW Toolkit V5 to pull the variable out and copy it into an accessible global variable called g.useragent :

<mvt:item name="toolkit" param="vassign|useragent|s.http_user_agent" />
&mvt:global:useragent;

Re: browser detection

try:

&mvt:s:http_user_agent; 
<mvt:if expr="'mozilla' CIN s.http_user_agent">
Hey, its Mozilla
</mvt:if>

the first line SHOWS the user agent, you need to use the other form when testing the contents of the variable

That's really odd... The first line doesn't seem to show anything for me.
But the testing of the variable appears to work fine.

I couldn't get it to print the variable when I first tried, too -that's what made me think that the variable was not available via Storemorph. Hence, I tried it with the Toolkit.

Is it just me, or does the

&mvt:s:http_user_agent;

not display anything for anyone else?

Re: browser detection

Awesome. I love Toolkit. :)

This is what I have so far - it's not the greatest but it's simple. I'm sure somebody can make a rock awesome geeked out version.

PS: I can confirm that &mvt:s:http_user_agent; renders nothing but can be used in an if statement if necessary: <mvt:if expr=" 'windows' CIN s.http_user_agent "> So I'm using the toolkit version since I use a LOT of toolkit everywhere else.

Re: browser detection

What about
<mvt:item name="toolkit" param="vassign|agent|http_user_agent" />
&mvte:global:agent;

Re: browser detection

This is way cool because now I can load up different javascript source files depending on what the customer is using. This is giong to save bandwidth and load times. Woohoo!
