Scrolling News for OsCommerce

[kenle]

Hi all,

 

I would like to have a scrolling news at the middle column, not on the right or the left of Oscommerce. It should be like the newsdesk module but be able to scrolling. And when the user put the mouse over it, it should stop. You can look at this website and see what I mean: http://www.flying-hobby.com/

 

Does this module already exists somewhere or can I somehow modify some existing scrolling news on the side and make it to the middle column?

 

Thanks

I know that there is a port of oscommerce called osc2nuke which includes the CMS PHPNuke and this has scrolling news modules and other features which may be of use to you.

Is this what you are looking for?

Notice the scroll box on the bottom.

 

If so, I can guide you on how to create this.

 

STEP 1: Create a table or box to place the scroller into.

 

STEP 2: Copy the following coding and paste it into your box

 

        <!-- start scroller -->
<script language="JavaScript1.2">

//Specify the marquee's width (in pixels)
var marqueewidth="320px"
//Specify the marquee's height
var marqueeheight="100px"
//Specify the marquee's marquee speed (larger is faster 1-10)
var marqueespeed=1
//Pause marquee onMousever (0=no. 1=yes)?
var pauseit=1

//marquee content
var marqueecontent='<?php echo your new query><b><a href=newspage.php?nid=$nid>$title</a></b><br><br>$newsteaser<br><br><hr><?php>'

marqueespeed=(document.all)? marqueespeed : Math.max(1, marqueespeed-1) //slow speed down by 1 for NS
var copyspeed=marqueespeed
var pausespeed=(pauseit==0)? copyspeed: 0
var iedom=document.all||document.getElementById
var actualheight=''
var cross_marquee, ns_marquee

function populate(){
if (iedom){
cross_marquee=document.getElementById? document.getElementById("iemarquee") : document.all.iemarquee
cross_marquee.style.top=parseInt(marqueeheight)+8+"px"
cross_marquee.innerHTML=marqueecontent
actualheight=cross_marquee.offsetHeight
}
else if (document.layers){
ns_marquee=document.ns_marquee.document.ns_marquee2
ns_marquee.top=parseInt(marqueeheight)+8
ns_marquee.document.write(marqueecontent)
ns_marquee.document.close()
actualheight=ns_marquee.document.height
}
lefttime=setInterval("scrollmarquee()",20)
}
window.onload=populate

function scrollmarquee(){

if (iedom){
if (parseInt(cross_marquee.style.top)>(actualheight*(-1)+8))
cross_marquee.style.top=parseInt(cross_marquee.style.top)-copyspeed+"px"
else
cross_marquee.style.top=parseInt(marqueeheight)+8+"px"
}
else if (document.layers){
if (ns_marquee.top>(actualheight*(-1)+8))
ns_marquee.top-=copyspeed
else
ns_marquee.top=parseInt(marqueeheight)+8
}
}

if (iedom||document.layers){
with (document){
if (iedom){
write('<div style="position:relative;width:'+marqueewidth+';height:'+marqueeheight+';overflow:hidden" onMouseover="copyspeed=pausespeed" onMouseout="copyspeed=marqueespeed">')
write('<div id="iemarquee" style="position:absolute;left:0px;top:0px;width:100%;">')
write('</div></div>')
}
else if (document.layers){
write('<ilayer width='+marqueewidth+' height='+marqueeheight+' name="ns_marquee">')
write('<layer name="ns_marquee2" width='+marqueewidth+' height='+marqueeheight+' left=0 top=0 onMouseover="copyspeed=pausespeed" onMouseout="copyspeed=marqueespeed"></layer>')
write('</ilayer>')
}
}
}
</script>
<!-- end scroller -->

 

STEP 3: In the above code you will look for this:

 

//marquee content
var marqueecontent='<?php echo your new query><b><a href=newspage.php?nid=$nid>$title</a></b><br><br>$newsteaser<br><br><hr><?php>'

 

And need to adjust the following items:

 

1. Add your new query string above where it says <!-- start scroller -->

2. Alter the above code and variables to match the items in the database.

3. Loop the string above so all news ends up between

 

var marqueecontent ''

 

NOTE: This is the one bug I found in this script above. If you have articles which use line breaks like this:

 

"my news article 1, paragraph 1.

 

my news article 1, paragraph 2. "

 

It will toss an error since the browser would see this:

 

var marqueecontent 'my news article 1, paragraph 1. 

my news article 1, paragraph 2.'

 

and consider that an unclosed script.

 

So you will have to do some legwork and find the equal php statement to automatically filter out any line breaks in your news. Make sense?

 

I know you may have been expecting an existing contribution for this, but with a little work this will work perfectly. I will eventually put this together as a contribution, but this is what I can offer for now.
