Hint in some fields for user registration.
 

QT helped me to add hints in user registration forms. Here is the link: http://www.computer-expert.bg/register.php

Here is the install instruction:

As described on the page provided, to implement the hint code you need to add the code below the 'Step 1' section to the 'head' section of the pages, and the code provided under the 'Step 2' to the form on the page.
Thus, you need to place the code under 'Step 1' to the <xcart_dir>/skin1/customer/home.tpl template to the 'head' section. Also you need to wrap the code with the Smarty 'literal' tag, for example:

Here is the code:
================================================== ==
{literal}
<style type="text/css">

#hintbox{ /*CSS for pop up hint box */
position:absolute;
top: 0;
background-color: lightyellow;
width: 150px; /*Default width of hint.*/
padding: 3px;
border:1px solid black;
font:normal 11px Verdana;
line-height:18px;
z-index:100;
border-right: 3px solid black;
border-bottom: 3px solid black;
visibility: hidden;
}

.hintanchor{ /*CSS for link that shows hint onmouseover*/
font-weight: bold;
color: navy;
margin: 3px 8px;
}

</style>

<script type="text/javascript">

var horizontal_offset="9px" //horizontal offset of hint box from anchor link

/////No further editting needed

var vertical_offset="0" //horizontal offset of hint box from anchor link. No need to change.
var ie=document.all
var ns6=document.getElementById&&!document.all

function getposOffset(what, offsettype){
var totaloffset=(offsettype=="left")? what.offsetLeft : what.offsetTop;
var parentEl=what.offsetParent;
while (parentEl!=null){
totaloffset=(offsettype=="left")? totaloffset+parentEl.offsetLeft : totaloffset+parentEl.offsetTop;
parentEl=parentEl.offsetParent;
}
return totaloffset;
}

function iecompattest(){
return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}

function clearbrowseredge(obj, whichedge){
var edgeoffset=(whichedge=="rightedge")? parseInt(horizontal_offset)*-1 : parseInt(vertical_offset)*-1
if (whichedge=="rightedge"){
var windowedge=ie && !window.opera? iecompattest().scrollLeft+iecompattest().clientWid th-30 : window.pageXOffset+window.innerWidth-40
dropmenuobj.contentmeasure=dropmenuobj.offsetWidth
if (windowedge-dropmenuobj.x < dropmenuobj.contentmeasure)
edgeoffset=dropmenuobj.contentmeasure+obj.offsetWi dth+parseInt(horizontal_offset)
}
else{
var windowedge=ie && !window.opera? iecompattest().scrollTop+iecompattest().clientHeig ht-15 : window.pageYOffset+window.innerHeight-18
dropmenuobj.contentmeasure=dropmenuobj.offsetHeigh t
if (windowedge-dropmenuobj.y < dropmenuobj.contentmeasure)
edgeoffset=dropmenuobj.contentmeasure-obj.offsetHeight
}
return edgeoffset
}

function showhint(menucontents, obj, e, tipwidth){
if ((ie||ns6) && document.getElementById("hintbox")){
dropmenuobj=document.getElementById("hintbox")
dropmenuobj.innerHTML=menucontents
dropmenuobj.style.left=dropmenuobj.style.top=-500
if (tipwidth!=""){
dropmenuobj.widthobj=dropmenuobj.style
dropmenuobj.widthobj.width=tipwidth
}
dropmenuobj.x=getposOffset(obj, "left")
dropmenuobj.y=getposOffset(obj, "top")
dropmenuobj.style.left=dropmenuobj.x-clearbrowseredge(obj, "rightedge")+obj.offsetWidth+"px"
dropmenuobj.style.top=dropmenuobj.y-clearbrowseredge(obj, "bottomedge")+"px"
dropmenuobj.style.visibility="visible"
obj.onmouseout=hidetip
}
}

function hidetip(e){
dropmenuobj.style.visibility="hidden"
dropmenuobj.style.left="-500px"
}

function createhintbox(){
var divblock=document.createElement("div")
divblock.setAttribute("id", "hintbox")
document.body.appendChild(divblock)
}

if (window.addEventListener)
window.addEventListener("load", createhintbox, false)
else if (window.attachEvent)
window.attachEvent("onload", createhintbox)
else if (document.getElementById)
window.onload=createhintbox

</script>
{/literal}

================================================== ===

The code of the link under the 'Step 2' section should be placed to the <xcart_dir>/skin1/customer/main/register.tpl template and probably also to the following template depending on to what fields you wish to add the hints:

Here is the code:
================================================== ===
<a href="#" class="hintanchor" onMouseover="showhint('Please choose a username. Should consist of alphanumeric characters only.', this, event, '150px')">[?]</a>
================================================== ===

Apply the second code in what part of registration you prefer:

<xcart_dir>/skin1/customer/main/register_personal_info.tpl
<xcart_dir>/skin1/customer/main/register_billing_address.tpl
<xcart_dir>/skin1/customer/main/register_shipping_address.tpl
<xcart_dir>/skin1/customer/main/register_contact_info.tpl
<xcart_dir>/skin1/customer/main/register_additional_info.tpl
<xcart_dir>/skin1/customer/main/register_ccinfo.tpl
<xcart_dir>/skin1/customer/main/register_account.tpl


I hope this is useful to someone.
