Coldfusion 2016 how to include template when using cfscript mail()? - coldfusion

A simple example of what I'm trying to accomplish using tag based code:
<cfmail
to="someone#x.com"
from="someone#y.com"
subject="howdy"
type="html">
<cfinclude template="path/to/emailtemplates/sometemplate.htm"/>
</cfmail>
I've tried all manner of solutions using cfscript and am at a roadblock. I thought this might do it, but alas no.
savecontent variable="mailBody" {
include "path/to/emailtemplates/sometemplate.htm";
};
mail = new mail();
mail.setTo( "someone#x.com" );
mail.setFrom( "someone#y.com" );
mail.setSubject( "howdy!" );
mail.setType( "HTML" );
mail.setBody( mailBody );
mail.send();
We're not sending multi-part e-mails - just HTML. Is there a way to do this in script?

The issue is that, in cfinlcude you will not be able to include an HTML file. Looks like you are going to need the help of FileRead() function instead of include.
mailBody=FileRead('absolute/path/to/emailtemplates/sometemplate.htm' [, charsetIfNeeded]);
For FileRead to work you should provide an absolute path to an on-disk or in-memory text file on the server.

Not sure if this answers the initial question but fyi in coldfusion 10 I used to be able to tell CF to process other files than cfm. In your application use this line:
<cfset THIS.compileextforinclude = "htm" />

coldfusion 10 cfinclude gives site cannot be reached error

I have a action page that redirects to a page based on condition.
I thought of Including that page insted of redirection.
So i used cfinclude function to include this file.
But including that file doesn't work.
But when i open that page in browser it is working fine without error.
For Ex.
http://domain.com/page2.cfm?cutomerID=10
is working fine.
IN http://domain.com/page1.cfm
I am including below code.
<cfset url.customerID = 10>
<cfinclude template="page2.cfm">
Even i tried to add only HTML content which i get in page source for "http://domain.com/page2.cfm?cutomerID=10"
It is still not working including a coldfusion page with just html text without any coldfusion code.
Strange thing is When i tried to remove some text from this html content it works for some time but when i reload it stops and give the below error again.
I am not sure if cfinclude has to do anything page length or some other factors.
Screenshot for error is attached below.

If you are asking for a link you can have it as:
<cfoutput>
<cfset href="domain.com/page2.cfm?customerID=#customerid#&etc=#etc#" />
</cfoutput>
For your question you can use this:
<cfset custID = 10/>
<cfinclude template="page2.cfm">
In page2.cfm:
<cfif isDefined(url.customerID) || isDefined(custID)>
<!--- your etc code here --->
</cfif>
Note: If you don't want to use url.customerID you can simply delete the occurance

Parsing og: tags with ColdFusion regex

If one wants to extract/match Open Graph (og:) tags from html, using regex (and ColdFusion 9+), how would one go about doing it?
And the tricky bit is that is has to cover both possible variations of tag formation as in the following examples:
<meta property="og:type" content="website" />
<meta content="website" property="og:type"/>
So far all I got is this:
<cfset tags = ReMatch('(og:)(.*?)>',html_content)>
It does match both of the links, however only the first type has the content bit returned with it. And content is something that I require.
Just to make it absolutely clear, the desired output should be an array with all of the OG tags (they could be 'type,image,author,description etc.). That means it should be flexible and not based on the og:type example alone.
Of course if it's possible, the ideal output would be a struct with the first column being the name of tag, and the second containing the value (content). But that can be achieved with the post processing and is not as important as extracting the tags themselves.
Cheers,
Simon
So you want an array like ['og:author','og:type', 'og:image'...]?
Try using a regex like og:([\w]+)
That should give you a start. You will have duplicates if you have two of the same og:foo meta tags.
You can look at JSoup also to help parse the HTML for you. It makes it a lot easier.
There are a few good blog posts on using it in CFML
jQuery-like parsing in Java
Parsing, Traversing, And Mutating HTML With ColdFusion And jSoup
Ok, so after the suggestion from #abbottmw (thank you very much!), here's the solution:
Download Jsoup jar file from here: http://jsoup.org/download
Then initiate it like this:
<cfhttp url="...." result="oghtml" > /*to get your html content*/
<cfscript>
paths = expandPath("/lib/jsoup.jar"); //or wherever you decide to place the file
loaderObj =createObject("component","javaloader.JavaLoader").init([expandPath('/lib/jsoup.jar')]);
jsoup = loaderObj.create("org.jsoup.Jsoup");
doc = jsoup.parse(oghtml);
tags = doc.select("meta[property*=og:]");
</cfscript>
<cfloop index="e" array="#tags#">
<cfoutput>
#e.attr("property")# | #e.attr("content")#<br />
</cfoutput>
</cfloop>
And that is it. The complete list of og tags is in the [tags] array.
Of course it's not the regex solutions, which was originally requested, but hey, it works!

Replace url in all hrefs inside body tags

I am using cfhttp to get a website . I want to replace all the links inside the body tags. Importantly I don't want to mess up the stylesheets etc in the head.
I want to do the following:
In the external web page body we may find a link:
External Link
I want to replace it with the following:
External Link
Its easy enough using Replace() but then I also replace all the linked stylesheets etc. I just want to edit the href's of clickable links.
I've modified an HTML document's DOM to add tracking parameters to links in outbound email messages using the jsoup library. (jsoup is an open source Java HTML Parser and can be download at http://jsoup.org/.) You'll note that it uses jQuery-like select methods, but all manipulations are performed on the server-side (I've also used it for removing ads from CFHTTTP-fetched HTML.)
Here's a quick sample of working ColdFusion code that will do exactly what you want on the server-side:
<CFSET TheHTML = CFHTTP.FileContent>
<CFSET jsoup = CreateObject("java", "org.jsoup.Jsoup")>
<CFSET TempHTML = jsoup.parse(TheHTML)>
<CFLOOP ARRAY="#TempHTML.select('a')#" INDEX="ThisLink">
<CFSET TheLink = thisLink.attr("href").toString()>
<CFSET TheHTML = replace(TheHTML, TheLink, "http://mywebsite.com/?u=" & URLEncodedFormat(TheLink))>
</CFLOOP>

cf10 unable to add text to HTML Head

I am getting the following error on a page we are loading:
coldfusion.runtime.CfErrorWrapper
Unable to add text to HTML HEAD tag.
[empty string]
caused by
Template
Unable to add text to HTML HEAD tag.
ColdFusion was unable to add the text you specified to the output stream. This is probably because you have already used a CFFLUSH tag in your template or buffered output is turned off.
I've done a sweep of all the files that are included in our application and cannot find anything that uses CFFlush.
output is set to 'no' on all cfcs and components. I also tried adding cfsetting showdebugoutput = no in a file. That didn't help.
I turned request debugging on in cfadmin and that didn't help.
The HTML Head works fine in other parts of our app, it just seems to be on this one page.
The only thing really different about this page is that it is a particularly long page.
If it's a particularly long page, then CF may be flushing the buffer on its own. If you check in the CFAdmin, on the settings page, there is a setting for Maximum Output Buffer size. I believe the default is 1024 KB. If your page is over 1 meg of content, then CF may flush the buffer before your <cfhtmlhead /> tag runs. Try increasing the buffer size, or changing the placement of the <cfhtmlhead /> tag to see if that corrects the issue.
I've run into the same problem recently but the behavior wasn't predictable. I believe that Dan Short's answer is correct. I created some test pages to see if I could reproduce the problem. Each time TestTemplate.cfm is included, CFHTMLHEAD writes a simple JavaScript alert to the head tag. Once the buffer is reached, and the page is automatically flushed, any subsequent CFHTMLHEAD tag use will result in an error, specifically, the error in the original post. As Dan indicates, you can work your way around this issue by changing the maximum output buffer size.
file: index.cfm

<cfset SampleScript = "<script src='sample.js'></script>">
cfset Count = 0>

l = j * k;
writeOutput(l);

alert('Boo!');
server.log showed another error that I was submitting too many fields with a POST request. I had to increase this limit on the Settings page.
To fix this, login to Coldfusion Admin, go to Memory Variables, and uncheck 'Disable updating Coldfusion internal cookies using Coldfusion tags/functions.' Save your settings and restart your website.

White Space / Coldfusion

What would be the correct way to stop the white space that ColdFusion outputs?
I know there is cfcontent and cfsetting enableCFoutputOnly. What is the correct way to do that?
In addition to <cfsilent>, <cfsetting enablecfoutputonly="yes"> and <cfprocessingdirective suppressWhiteSpace = "true"> is <cfcontent reset="true" />. You can delete whitespaces at the beginning of your document with it.
HTML5 document would then start like this:
<cfcontent type="text/html; charset=utf-8" reset="true" /><!doctype html>
XML document:
<cfcontent reset="yes" type="text/xml; charset=utf-8" /><CFOUTPUT>#VariableHoldingXmlDocAsString#</CFOUTPUT>
This way you won't get the "Content is not allowed in prolog"-error for XML docs.
If you are getting unwanted whitespaces from a function use the output-attribute to suppress any output and return your result as string - for example:
<cffunction name="getMyName" access="public" returntype="string" output="no">
<cfreturn "Seybsen" />
</cffunction>
You can modify the ColdFusion output by getting access to the ColdFusion Outpout Buffer. James Brown recently demo'd this at our user group meeting (Central Florida Web Developers User Group).
<cfscript>
out = getPageContext().getOut().getString();
newOutput = REreplace(out, 'regex', '', 'all');
</cfscript>
A great place to do this would be in Application.cfc onRequestEnd(). Your result could be a single line of HTML which is then sent to the browser. Work with your web server to GZip and you'll cut bandwidth a great deal.
In terms of tags, there is cfsilent
In the administrator there is a setting to 'Enable whitespace management'
Futher reading on cfsilent and cfcontent reset.
If neither <cfsilent> nor <cfsetting enablecfoutputonly="yes"> can satisfy you, then you are probably over-engineering this issue.
When you are asking solely out of aesthetic reasons, my recommendation is: Ignore the whitespace, it does not do any harm.
Alternatively, You can ensure your entire page is stored within a variable and all this processing is done within cfsilent tags. e.g.
<cfsilent>
<!-- some coldfusion -->
<cfsavecontent variable="pageContent">
<html>
<!-- some content -->
</html>
</cfsavecontent>
<!-- reformat pageContent if required -->
</cfsilent><cfoutput>#pageContent#</cfoutput>
Finally, you can perform any additional processing after you've generated the pagecontent but before you output it e.g. a regular expression to remove additional whitespace or some code tidying.
Here's a tip if you use CFC.
If you're not expecting your method to generate any output, use output="false" in <cffunction> and <cfcomponent> (not needed only if you're using CF9 script style). This will eliminate a lot of unwanted whitespaces.
If you have access to the server and want to implement it on every page request search for and install trimflt.jar. It's a Java servlet filter that will remove all whitespace and line breaks before sending it off. Drop the jar in the /WEB-INF/lib dir of CF and edit the web.xml file to add the filter. Its configurable as well to remove comments, exclude files or extensions, and preserve specific strings. Been running it for a few years without a problem. A set it and forget it solution.
I've found that even using every possible way to eliminate whitespace, your code may still have some unwanted spaces or line breaks. If you're still experiencing this you may need to sacrifice well formatted code for desired output.
for example, instead of:
<cfprocessingdirective suppressWhiteSpace = "true">
<cfquery ...>
...
...
...
</cfquery>
<cfoutput>
Welcome to the site #query.userName#
</cfoutput>
</cfprocessingdirective>
You may need to code:
<cfprocessingdirective suppressWhiteSpace = "true"><cfquery ...>
...
...
...
</cfquery><cfoutput>Welcome to the site #query.UserName#</cfoutput></cfprocessingdirective>
This isn't CF adding whitespace, but you adding whitespace when formatting your CF.
