I may be being dim here, as I often am with jscript
, but surely if the following code goes into jscript management and is made available for all pages it's being linked to in the head? Therefore, on phpbb3 you just need to put in the jscript management?
- Code:
//Style Sheet Switcher version 1.1 Oct 10th, 2006
//Author: Dynamic Drive: http://www.dynamicdrive.com
//Usage terms: http://www.dynamicdrive.com/notice.htm
var manual_or_random="manual" //"manual" or "random"
var randomsetting="3 days" //"eachtime", "sessiononly", or "x days (replace x with desired integer)". Only applicable if mode is random.
//////No need to edit beyond here//////////////
function getCookie(Name) {
var re=new RegExp(Name+"=[^;]+", "i"); //construct RE to search for target name/value pair
if (document·cookie.match(re)) //if cookie found
return document·cookie.match(re)[0].split("=")[1] //return its value
return null
}
function setCookie(name, value, days) {
var expireDate = new Date()
//set "expstring" to either future or past date, to set or delete cookie, respectively
var expstring=(typeof days!="undefined")? expireDate.setDate(expireDate.getDate()+parseInt(days)) : expireDate.setDate(expireDate.getDate()-5)
document·cookie = name+"="+value+"; expires="+expireDate.toGMTString()+"; path=/";
}
function deleteCookie(name){
setCookie(name, "moot")
}
function setStylesheet(title, randomize){ //Main stylesheet switcher function. Second parameter if defined causes a random alternate stylesheet (including none) to be enabled
var i, cacheobj, altsheets=[""]
for(i=0; (cacheobj=document.getElementsByTagName("link")[i]); i++) {
if(cacheobj.getAttribute("rel").toLowerCase()=="alternate stylesheet" && cacheobj.getAttribute("title")) { //if this is an alternate stylesheet with title
cacheobj.disabled = true
altsheets.push(cacheobj) //store reference to alt stylesheets inside array
if(cacheobj.getAttribute("title") == title) //enable alternate stylesheet with title that matches parameter
cacheobj.disabled = false //enable chosen style sheet
}
}
if (typeof randomize!="undefined"){ //if second paramter is defined, randomly enable an alt style sheet (includes non)
var randomnumber=Math.floor(Math.random()*altsheets.length)
altsheets[randomnumber].disabled=false
}
return (typeof randomize!="undefined" && altsheets[randomnumber]!="")? altsheets[randomnumber].getAttribute("title") : "" //if in "random" mode, return "title" of randomly enabled alt stylesheet
}
function chooseStyle(styletitle, days){ //Interface function to switch style sheets plus save "title" attr of selected stylesheet to cookie
if (document.getElementById){
setStylesheet(styletitle)
setCookie("mysheet", styletitle, days)
}
}
function indicateSelected(element){ //Optional function that shows which style sheet is currently selected within group of radio buttons or select menu
if (selectedtitle!=null && (element.type==undefined || element.type=="select-one")){ //if element is a radio button or select menu
var element=(element.type=="select-one") ? element.options : element
for (var i=0; i<element.length; i++){
if (element[i].value==selectedtitle){ //if match found between form element value and cookie value
if (element[i].tagName=="OPTION") //if this is a select menu
element[i].selected=true
else //else if it's a radio button
element[i].checked=true
break
}
}
}
}
if (manual_or_random=="manual"){ //IF MANUAL MODE
var selectedtitle=getCookie("mysheet")
if (document.getElementById && selectedtitle!=null) //load user chosen style sheet from cookie if there is one stored
setStylesheet(selectedtitle)
}
else if (manual_or_random=="random"){ //IF AUTO RANDOM MODE
if (randomsetting=="eachtime")
setStylesheet("", "random")
else if (randomsetting=="sessiononly"){ //if "sessiononly" setting
if (getCookie("mysheet_s")==null) //if "mysheet_s" session cookie is empty
document·cookie="mysheet_s="+setStylesheet("", "random")+"; path=/" //activate random alt stylesheet while remembering its "title" value
else
setStylesheet(getCookie("mysheet_s")) //just activate random alt stylesheet stored in cookie
}
else if (randomsetting.search(/^[1-9]+ days/i)!=-1){ //if "x days" setting
if (getCookie("mysheet_r")==null || parseInt(getCookie("mysheet_r_days"))!=parseInt(randomsetting)){ //if "mysheet_r" cookie is empty or admin has changed number of days to persist in "x days" variable
setCookie("mysheet_r", setStylesheet("", "random"), parseInt(randomsetting)) //activate random alt stylesheet while remembering its "title" value
setCookie("mysheet_r_days", randomsetting, parseInt(randomsetting)) //Also remember the number of days to persist per the "x days" variable
}
else
setStylesheet(getCookie("mysheet_r")) //just activate random alt stylesheet stored in cookie
}
}
The links for the alternate CSS need to go somewhere, so why can't they go in the homepage message? The div that get's activated can be over-ridden with an inline style.
- Code:
<link rel="alternate stylesheet" type="text/css" media="screen" title="theme1" href="CSS1" />
<link rel="alternate stylesheet" type="text/css" media="screen" title="theme2" href="CSS2" />
<link rel="alternate stylesheet" type="text/css" media="screen" title="theme3" href="CSS3 />
The form itself is down to personal preference where it goes, but it should be able to go straight in a widget, or the homepage message, or a footer, with a little tweaking a drop down menu in the navbar, with a little more jscript, it could be added to the linklist/replace the linklist/replace the search that lives under the navbar.
- Code:
<form id="switchform">
<!-- Theme 1 -->
<input type="radio" name="choice" value="theme1" onClick="chooseStyle(this.value, 60)">Theme 1 Name
<!-- Theme 2 -->
<input type="radio" name="choice" value="theme2" onClick="chooseStyle(this.value, 60)">Theme 2 Name
<!-- Theme 3 -->
<input type="radio" name="choice" value="theme3" onClick="chooseStyle(this.value, 60)">Theme 3 Name
</form>
My preference would be a widget, but only because of ease of styling the form (instead of radials, you could have pictures and things
)
I'm probably missing something very obvious, though.
