PHP to Miva Scrip need some help

[Russ]

OK I have a great little scrip in PHP that lets me do some dynamic things based on peoples user agent, however I am having a bit of trouble figuring how to re-write this PHP using purely Miva Scrip, or how to include it so it executes properly.I recall that getting PHP to run in the HEAD is a bit problematic, but if it can be done that might be easier? I either need to get the PHP to run corectly in the HEAD section of MIVA pages or I need to rewrite it into Miva Script....The basics of the code are:$ua = $_SERVER['HTTP_USER_AGENT'];if ((preg_match('what I am looking for in the user agent', $ua)){ $user = "what I will test for latter to decide what to do";} else if ((preg_match('what I am looking for in the user agent', $ua)){ $user = "something else I will test for latter to decide what to do";} I also make use of the "||" or, "&&" and, and or the "!" not operators in these if else teststhen I runif ($user == "a value I set to test for"){ print "the HTML I want";}else if ($user == "another value I set to test for"){ print "the HTML I want";}any help I can get converting this PHP to MIVA or running this PHP in MIVA is much appreciated. I am basically getting caught up on properly passing the variable between to tests and how to execute preg_match() and $_SERVER['HTTP_USER_AGENT'] in Miva Script, or how to get these PHP instructions to properly execute if included in the HEAD section of a miva page. Either solution would work in this case.Thanks a million in advance.

OK I have a great little scrip in PHP that lets me do some dynamic things based on peoples user agent, however I am having a bit of trouble figuring how to re-write this PHP using purely Miva Scrip, or how to include it so it executes properly.

I recall that getting PHP to run in the HEAD is a bit problematic, but if it can be done that might be easier? I either need to get the PHP to run corectly in the HEAD section of MIVA pages or I need to rewrite it into Miva Script....

The basics of the code are:

$ua = $_SERVER['HTTP_USER_AGENT'];

if ((preg_match('what I am looking for in the user agent', $ua))
{
    $user = "what I will test for latter to decide what to do";
} 

else if ((preg_match('what I am looking for in the user agent', $ua))
{
    $user = "something else I will test for latter to decide what to do";
} 

I also make use of the "||" or, "&&" and, and or the "!" not operators in these if else tests

then I run

if ($user == "a value I set to test for")
{
  print "the HTML I want";
}
else if ($user == "another value I set to test for")
{
  print "the HTML I want";
} 

any help I can get converting this PHP to MIVA or running this PHP in MIVA is much appreciated. I am basically getting caught up on properly passing the variable between to tests and how to execute preg_match() and $_SERVER['HTTP_USER_AGENT'] in Miva Script, or how to get these PHP instructions to properly execute if included in the HEAD section of a miva page.

Re: PHP to Miva Scrip need some help

You could do this easily with actual mivascript

<mvif expr="{ 'WHAT YOU ARE LOOKING FOR IN USER AGENT' IN toupper(s.user_agent) }">
do this
<mvelseif expr="{ 'SOMETHING ELSE YOU ARE LOOKING FOR' IN toupper(s.user_agent) }">
do something else
<mvelse>
do the last thing
</mvif>

Do actually do it in a template, you'd need toolkit or toolbelt (and i don't know the syntax, but the Gist is the same).

Here's a complete list of system variables:

Re: PHP to Miva Scrip need some help

ok so something like:

else if ((preg_match('/iPad/i', $ua)) || (preg_match('/tablet/i', $ua)))
{
    /* This user agent is  on a tablet */
    $user = "result1";
} 

would become:

<mvelseif  expr="{ '/iPad/i' IN toupper(s.user_agent) || '/tablet/i' IN toupper(s.user_agent)  }">
<MvASSIGN NAME="g.User" VALUE="result1">

For my sanity making sure I am following the syntax correctly. Now if posible I would like to just be able to add the code like wise to the template so I guess I need to get familiar with the different syntax needed for toolkit or toolbelt should I contue on that here in this post or start a new one for the toolkit or tool belt side of this. I want to do both as I would like to add this functionality as a module so others can add it to any MIVA store with out the need to understand the functions, but for more advanced uses need to know how to likewise just add the functions directly to the template.

Re: PHP to Miva Scrip need some help

Close: "||" is OR in mivascript.

<mvelseif expr="{ '/iPad/i' IN toupper(s.user_agent) || '/tablet/i' IN toupper(s.user_agent) }">
<MvASSIGN NAME="g.User" VALUE="result1">

To use mivascript, you'd have to create a module (by following the Module API doc and asking tons of questions which are not answered by that do (and of course, get and install the compiler). But yea, can be done.

Another thing you could do is use the PHP to 'redirect' the customer by having that as the default "landing" page, using PHP code to do the detection, then, send them to either "merchant.mv?screen=XXXX&restof=merchant&variables =intheurl

Re: PHP to Miva Scrip need some help

Did MivaScript suddenly start using Regex?

Ya I am noticing a lack of compete documentation but to get the functionality I have with the PHP scrip I need to get this done. Unfortunately simple redirects would not work. As content is dynamic genrated based on user agent. If I did redirects would need to make 50 ver of each page just not practical to manage. I am confused on the whole || Vs OR thing are you saying I should use "OR" instead of ||. I ask because the code you posed is identical to what I wrote as far as I can see.

Re: PHP to Miva Scrip need some help

Yes, the mivascript command for || is OR.
