Question

Coldfusion tags within query output

I have a simple query to a SQL database that returns a record set. Within the record set is a field that contains HTML and CFML. When I display the content it reads the CF tags literally. Is there any way to get the CF tags to be processed when it is returned in the query output? See example below.


------------------ CODE ON PAGE -------------------------------
<CFQUERY name="getdata" datasource="DSN">
select ID, HTMLFIELD
from TABLENAME
where ID = '1'
</CFQUERY>

<CFOUTPUT QUERY="getdata">
#getdata.HTMLFIELD#
</CFOUTPUT>


-----------------------VALUE OF "HTMLFIELD" VARIABLE--------------------------------
<CFSET todaysdate = #DateFormat(Now(), "mm/dd/yyyy")#>
<p>Today is #variables.todaysdate#</p>


------------------------WHAT IS DISPLAYED IN THE BROWSER----------------
Today is #variables.todaysdate#


-----------------------WHAT should BE DISPLAYED IN THE BROWSER------------

Pete is right, very risky.

I've done a similar feature for a site I wrote that allowed users to edit pages on the fly, only I pre-selected functions that could be used and created wrappers for them. Then the users would insert something like $now()$ in the WYSIWYG. Then when the page was requested I would pass the data containing HTML and psuedo-CFML through parse routine which would render the end results in a controlled manner.

I would really recommend this route as you will have much more controll over the types of scripts that can be run. It is also easy to make buttons that insert the code for them.

Before I tell you how to do this, keep in mind that It is not recommended to allow users to execute CFML. They could delete databases, files, steal info. So if you are going to allow this you need to REALLY REALLY TRUST your users. It is a risky thing to do.

The way you can execute the code would be to write the code to a temporary file, and then use CFINCLUDE to include the file. Then delete the temp file once you are done with it.

But again, make sure you understand the risks before you implement this.
