If you send both, it works fine.

Plain
Strong HTML

So, if you’re sending plain only, don’t put it in a cfmailpart. Probably shouldn’t have been in the first place, but, issue now solved.

* {
direction: rtl;
unicode-bidi: bidi-override;
}

a,abbr,acronym,address,applet,area,b,base,basefont,bdo,big,blockquote,body,br,
button,caption,center,cite,code,col,colgroup,,dd,del,dfn,dir,div,dl,dt,em,fieldset,
font,form,frame,frameset,h1,h2,h3,h4,h5,h6,head,hr,html,i,iframe,img,input,ins,
isinde,kbd,label,legend,li,link,map,menu,meta,noframes,noscript,object,ol,
optgroup,option,p,param,pre,q,s,samp,script,select,small,span,strike,strong,
style,sub,sup,table,tbody,td,textarea,tfoot,th,thead,title,tr,tt,u,ul,var

Anyway, they’ve just released version 1 and also a slightly more feature filled “Pro” version.

One alternative, and don’t get me wrong it’s not better because it’s still text however it will make it a bit harder for bots to spam you, is to ask a question and have the user give the answer.

In this example I’ll ask the question:

<blockquote>What is two added with four? Please enter the answer as a number.</blockquote>

Below is a very basic ColdFusion page with that example.

<!--- store the numbers as words in a list, could also been and array --->
<cfset numberWords = "one,two,three,four,five,six,seven,eight,nine,ten">
<!--- get two numbers --->
<cfset n1 = randrange(1,10)>
<cfset n2 = randrange(1,10)>
<!--- calculate the total --->
<cfset nt = n1 + n2>
<!--- hash that value so it can't be seen in the source --->
<cfset nh = hash(nt)>
<cfoutput>
What is #listGetAt(numberWords,n1)# added to #listGetAt(numberWords,n2)#?
</cfoutput>
<form name="frm" method="post" action="captcha.cfm">
<!--- store the hash value in the form --->
<input type="hidden" name="hashvalue" value="<cfoutput>#nh#</cfoutput>">
<input type="text" name="answer">
<input type="submit">
</form>
<!--- hash the user's answer and compare to the passed hashed value --->
<cfif isDefined("form.answer")>
<cfif hash(form.answer) neq form.hashvalue>
<p>Nope</p>
<cfelse>
<p>Yay!</p>
</cfif>
</cfif>

Hopefully that might help someone!

The form bit is pretty standard.

<div class="form-row">
<div class="field-label"><label for="field1">Username</label>:</div>
<div class="field-widget"><input name="field1" id="field1" class="text required validate-username" title="Enter yourusername." /></div>
</div>

The Javascript bit included on this page in an external JS file.

Validation.addAllThese([
['validate-username','Sorry, that username is already taken.',function(v,elm) {
if(elm._ajaxValidating && elm._hasAjaxValidateResult) {
elm._ajaxValidating = false;
elm._hasAjaxValidateResult = false;
return elm._ajaxValidateResult;
}
var sendRequest = function() {
new Ajax.Request('/path/to/check/file?username='+v+'&r='+Math.random(),{
onSuccess : function(response) {
elm._ajaxValidateResult = eval(response.responseText);
elm._hasAjaxValidateResult = true;
Validation.test('validate-username',elm);
}
});
elm._ajaxValidating = true;
return true;
}
return elm._ajaxValidating || Validation.get('IsEmpty').test(v) || sendRequest();
}]
]);

The Javascript bit in the page.

<script language="javascript" type="text/javascript">
var valid_register = new Validation('register', {immediate:true,stopOnFirst:true,onSubmit:false});
</script>

The form is submitted with an Event.observe on the submit button I have as well.

And so concludes my first geekish post for a while, it feels strangely good!

The CSS file in question is quite large, a couple of hundred lines or so, in amungst it was a simple class:

#text p, { padding: 0; margin: 0; color: #ffffff; }

The issue was that the first paragraph tag in the text div had extra padding on the top whereas in IE it wasn’t there. The comma should be an obvious spot but within the larger file I’d overlooked it. Ah well… back to the CSS grindstone!

Quite an easy task, cfhttp the file, loop over it, insert to the database. Well, this was made even easier by me discovering the entirely not new XPath (or here). Another quick google found a tutorial and after a quick play using xmlParse() and xmlSearch() in Coldfusion 7 my feed was filtered and inserted for reuse. It’s been around for a while, but, if you’re using CF7 and working with XML and haven’t seen XPath I suggest you take a look.

Quite nice as well as I actually learned something today!
