Converting From PHP

[jdyerjdyer]

I'm converting a site from PHP to ColdFusion and need to find a compatible feature as __LINE__ magic variable in php to report the line number currently executing for logging purposes.

Here is a solution I finally found after searching for three days.
It's hidden on the
[url]http://livedocs.macromedia.com/coldfusion/6.1/htmldocs/errors31.htm#wp1131396[/url]
Exception information in catch blocks. I'm not sure if I have the right
number index, but it shouldn't be off by more than one or two. Haven't had a
chance to test yet, but pretty sure this works.

<!--- Get line number of error. --->
<cftry>
<cfthrow type = "get_line_number">
<cfcatch type = "get_line_number">
<cfset err_tag = #CFCATCH.TAGCONTEXT[3]#>
<cfset err_line = #err_tag["LINE"]#>
<cfset err_page = #err_tag["TEMPLATE"]#>
</cfcatch>
</cftry>
<!--- End Get line number of error. --->

The example works except for one thing. The number must be 1 for some reason,
and this always returns the line containing the throw tag. The documentation
says the structure should contain information on all open tags, but in all my
tests, it only allows for the number 1. At least this works good enough for my
problem, if not a little lengthy, but at least it works. If anyone knows how
to get the information from the other opened tags, (i.e. the cfif tag
immediately containing this code, please enlighten me.

I am happy you found an answer. You will find some things to me lengthier than
in php, but many things to be alot simpler than in php. The key is to get the
job done.

Goodluck with whatever you're doing.

the line number is where you told cf there was that specific type of error
w/cfthrow. you could use "Any" to trap all errors or specific cfcatch blocks
w/their own logic if you wanted more granular control. and this info is not
what i would call "hidden".
