so I know by using these headers at the top:
<cfcontent type="application/msword; cht=utf-8">
<cfheader name="Content-Type" value="application/msword">
<cfheader name="Content-Disposition" value="attachment;
filename=Staff-List.doc">
the site opens in a word document, but I want to have the site open normally and then if I click a button, for example "donwload as word" then it downloads, but I can't find anywhere the syntax to do even something similar, how could I do it?
This is what I've tried so far
<cfif isDefined("url.submit_docs")>
<cfcontent type="application/msword; cht=utf-8">
<cfheader name="Content-Type" value="application/msword">
<cfheader name="Content-Disposition" value="attachment;
filename=Staff-List.doc"></cfif>
I have the information withing a form, and when I click the "download as word" button which name is "submit_docs" I get a browser error indicating it cannot locate the file.
The form looks something like this:
<form >
<div id="MainWrapper" >
<cfoutput>
my info
</cfoutput>
<input type= 'submit' value= 'Download as MS word' name="submit_docs">
</form>
This might be silly, but based on your code this line:
<cfif isDefined("url.submit_docs")>
Should be referencing a FORM element as in:
<cfif isDefined("FORM.submit_docs")>
Your submit button is inside a form correct?
There is also a "file" attribute to the tag... so you can do this:
<cfcontent type="application/msword; cht=utf-8" file="filename=Staff-List.doc">
I usually add headers as well, but I'm not sure they are needed.

I am severely new to ColdFusion... I have searched for help on this statement and have found a bunch of material, but still don't understand what is going on. All of the parts of this statement make sense, but when I put them all together, it's confusing... the ColdFusion 8: IsDefined("URL.variable) and is not"" thread is the closest, but I still don't understand. This is the 1st statement in the index.cfm file of my application. It's not throwing an error, I just want to understand how it works. Thank you.
I have yet to be able to successfully post code here, so here is a link to a text version of the index.cfm.
Edit:
The code below should be the relevant sections related to URL.openFile
<cfif isdefined("URL.openFile")>
<cfquery name="getFile" datasource="xxxxxxxx">
SELECT filename, filename2, filecontent, filesize
FROM Help_FooterInfo
WHERE Help_id=5 and Section='Registration'
</cfquery>
<cfset sproot=#getDirectoryFromPath(getTemplatePath())#>
<cfset newDest = #sproot#&"temp\">
<cfoutput query="getFile">
<cfheader name="Content-Disposition" value="attachment; filename=#getfile.FileName2#">
<cfcontent type="application/msword" variable="#getfile.filecontent#">
</cfoutput>
</cfif>
...
<cfquery name="getRegistration" datasource="xxxxxxxx">
select * from help_footerinfo where help_id=5
</cfquery>
....
<cfoutput>#getRegistration.Content#</cfoutput><br>
<a href="<cfif #getRegistration.filename2# neq "">index.cfm?openfile=Yes</cfif>" target="_blank">
<u><cfoutput>#getRegistration.FileName#</cfoutput></u>
</a>
The error message I am receiving (see comment below): ORA-00942: table or view does not exist (ColdFusion application)
This:
<cfif IsDefined("URL.variable") and URL.variable is not "" >
means, "If url.variable actually exists and is not an empty string".
A better alternative for isDefined("URL.variable") is StructKeyExists(url,"variable").
Other alternatives for is not "" include len(trim(url.variable)) gt 0, and isNumeric(url.variable).
I know how to upload an image file to a server and show the image file to a page.
But what if I want a preview on a confirmation page?
I can probably generate a temp file that isn't saved in the database but is a file in a physical location, but what if I decided to hit the "no" button. How would this temp file be deleted?
The code below shrinks the image and shows it on the page. But it also creates an image within the directory, that will stay there after I hit OK or NO. The NO is button, while the OK naturally is a submit.
<!--- Make Temp Image as Preview --->
<cfset mediapath = expandpath('../images/about')>
<cfif structKeyExists(form,"image") and len(form.image)>
<cffile action="upload"
filefield="image"
destination="#MediaPath#"
nameconflict="makeunique">
<cfimage name="uploadedImage"
source="#MediaPath#/#file.serverFile#" >
<cfset imagesize = 320>
<cfif uploadedImage.width gt uploadedImage.height>
<cfset percentage = (imagesize / uploadedImage.width)>
<cfelse>
<cfset percentage = (imagesize / uploadedImage.height)>
</cfif>
<cfset newWidth = round(uploadedImage.width * percentage)>
<cfset newHeight = round(uploadedImage.height * percentage)>
<!--- Show Image --->
<cfoutput>
<img src="../images/about/#file.serverFile#" style="height:#newHeight#; width:#newWidth#;">
I assume I may have to do URL Passing or do some sort of CFScript. On the Return buttons Onclick event.
Here is my approach take it for what you will.
Ok this is probably more than you need but this should get you somewhere on this image delete problem thing.
Here is your code. But I broke it into two pages. Of course I cannot see what else is going on this page and your form handling stuff so we will start with what you are giving us.
<cfset mediapath = expandpath('../images/about')>
nice use of structKeyExists() :)
<cfif structKeyExists(form,"image") and len(form.image)>
Here I would pause and suggest you limit
your uploads to just .gif, .jpeg, .jpg, .png
(your main image types) to prevent uploading any
and everyfile type. I added an accept parameter below.
<cffile action="upload"
filefield="image"
destination="#MediaPath#"
nameconflict="makeunique"
accept="image/*">
<cfimage name="uploadedImage"
source="#MediaPath#/#file.serverFile#" >
Ok the file is uploaded lets seperate concerns
At this point I would ask them if they want to preview the file. If they click 'preview' take them to a preview.cfm page.
Then you have a file name you need to pass if you have nothing else (like an ID or some primary key).
So I pulled this handy-dandy script out of the Adobe Coldfusion docs on their website and I am going to use this to turn your filename into 'something else' ;)
<cfscript>
theKey="123abc";
theKey=generateSecretKey("AES")
superDuperSecretSoDontTell=encrypt(file.serverFile, theKey, "AES", "hex");
</cfscript>
Let's send this piggy!
and off you go to the preview page...
<cfoutput>
(pointing up) This is pageA.cfm
(pointing down) This is pageB.cfm
Now I have the rest of your code below and lets pull your file based on the pass through querystring variable/value pairs.
<cfscript>
IWannaKnowTheSecret=decrypt(url.fileName, url.theKey, "AES", "hex");
</cfscript>
Here I would pause and suggest you limit
your uploads to just .gif, .jpeg, .jpg, .png
(your main image types) to prevent uploading any
and everyfile type. I added an accept parameter below.
<cffile action="read" file="#MediaPath##IWannaKnowTheSecret#" variable="uploadedImage">
<cfset imagesize = 320>
Interesting handle here. So you are taking the
larger of the two values and using that
to percentage down the size. Neat.
<cfif uploadedImage.width GT uploadedImage.height>
<cfset percentage = (imagesize / uploadedImage.width)>
<cfelse>
<cfset percentage = (imagesize / uploadedImage.height)>
</cfif>
<cfset newWidth = round(uploadedImage.width * percentage)>
<cfset newHeight = round(uploadedImage.height * percentage)>
Then do a form like this:
<form action="" method="post" enctype="multipart/form-data">
Your current Image:
<cfoutput>
Name: #uploadedImage#<br>
<img src="../images/about/#uploadedImage#" style="height:#newHeight#; width:#newWidth#;">
</cfoutput>
Do you want to remove this?<br>
<input type="checkbox"
name="removeImage"
value="1" />: Remove the logo image</cfif><br />
Wnat to replace your image?<br>
<input type="file" name="replacementImage"> (
<input type="hidden"
name="uploadedImage"
value="<cfoutput>#uploadedImage#</cfoutput>">
<input type="submit" value="submit" name="submit"
</form>
Cancel and go back
If they continue and want to fix the image or replace it. Submit then you can use something like this.
Then we delete...
And if the replacementImage file filed is populated then we add that file.
And there you have it...
You are seperating some concerns.
You are giving improved options.
You are allowing a change or no change.
You are giving them an out to go back to where ever you want.
Edit: Here is proof for the encoding and decoding stuff (if you wanted to play with it:
<cfscript>
theKey="123abc";
theKey=generateSecretKey("AES");
superDuperSecretSoDontTell=encrypt("monkeytoots", theKey, "AES", "hex");
</cfscript>
<cfoutput>Let's send this piggy!</cfoutput>
<cfif isdefined("url.fileName") and isdefined("url.theKey")>
<cfscript>
IWannaKnowTheSecret=decrypt(url.fileName, url.theKey, "AES", "hex");
</cfscript>
<cfoutput>
#IWannaKnowTheSecret#
</cfoutput>
</cfif>
This answer is in response to Adam Cameron's comment. It illustrates some potentially unexpected results that can occur with two submit buttons. Start with this code.
<cfdump var="#form#">
<form action="abc.cfm" method="post">
<input type="text" name="text1" />
<input type="submit" name="submit1" value="no" />
<input type="submit" name="submit2" value="yes" />
</form>
The default behaviour of most, if not all browsers is that there are occasions whereby a form will be submitted when the user presses the enter key. What would you expect to see with this form if you had your curser in the text box and pressed Enter? Try it and see if you were right.
I am working with a very old login system that my company used before on a website that used frames.
Before, when someone tried a wrong user/pass combination the frame would load a simple cfinclude file with the login form and an error message on top of it.
Now I am using a form in a popup window that calls the application.cfc but instead of getting the error message back on my popup window the page load the cfinclude file from the application component to a new page.
So I need a few things to happen for this application. First, I need the initial popup window to stay up and the page should not submit if the combination of user/pass is wrong, and finally I need the error message to appear somewhere on the popup.
If anyone did something like this before I would really appreciate your feedback.
This is a partial of my code:
Login Form:
<!--- loginErrMsg display - to tell why login is denied --->
<cfif isdefined("loginErrMsg")><span style="color:red">#loginErrMsg#</span><br /></cfif>
<form name="LoginForm" id="LoginForm" action="<cfif test is false>https://secure.example.com</cfif>#loginFormAction#" method="post" target="_top">
</cfoutput>
<input type="hidden" name="loginPost" value="true">
<p>
Login below to take advantage of the great services we offer:
</p>
E-mail:<input name="j_username" class="loginform" type="text" size="30" maxlength="50" id="j_username">
Password: <input name="j_password" type="password" size="30" maxlength="16" class="loginform">
<br />
<input type="submit" name="btn" value="Submit" class="bluebuttonnormal">
</form>
Application.cfc Code:
<cflogin applicationtoken="swmadmin">
<cfif NOT IsDefined("cflogin")>
<cfinclude template="login.cfm">
<cfabort>
<cfelse>
<cfquery name="userlookup" datasource="#ds#">
SELECT clientadminID, roles, isFaxOnly, acctEnabled FROM clientadmin
WHERE
username=<cfqueryparam value="#cflogin.name#" CFSQLTYPE="CF_SQL_VARCHAR" maxlength="50">

</cfquery>
<cfif userlookup.recordcount eq 0>
<cfset loginErrMsg = "Invalid login.">
<cfinclude template="login.cfm">
<cfabort>
</cflogin>
I am working with a very old login system that my company used before
on a website that used frames.
If this is a new website, don't use it. Login forms are a dime a dozen and can be done in your sleep. Start fresh and do it right.
So I need a few things to happen for this application. First, I need
the initial popup window to stay up and the page should not submit if
the combination of user/pass is wrong, and finally I need the error
message to appear somewhere on the popup.
You're going to want to use an AJAX solution here, either write your own or use a good library like jQuery. Once you check the login values you can use jQuery or simple javascript to unhide or update the innerHTML of an empty element to display your error message.
<cflogin ...>

CFLogin makes me sad. Another one of ColdFusion's tags meant to simplify something commonly done that doesn't really help much and sacrifices flexibility. You can get far more control over your application without it. instead of CFLogin, try something like this pseudo code
<cfcomponent>
<cffunction name = "onRequest" ...>
<cfargument name="targetPage" type="String" required = "true" />
<cfif !structKeyExists(session, "roles") and !findNoCase("loginHandler.cfm",cgi.script_name)>
<!--- notice I prevent the redirect on the form handler, otherwise the ajax will get redirected to the login.cfm page --->
<cfinclude template = "login.cfm">
<cfelse>
<cfinclude template = "#arguments.targetPage#">
</cfif>
</cffunction>
</cfcomponent>
Your login.cfm would then contain your form but your button would fire something like jQuery.post() to "loginHandler.cfm", then depending on the result of the login, your callback function may use jQuery.html() to display the error or window.location.replace / window.location.href if the login was successful. Of course, in the event of a successful login, your ColdFusion page would have to create their session variables and do whatever else you want it to do before sending the result back to your AJAX call.
cffile is giving a head ache now.
My cfm is like this -
`
<cfif session.ismac and session.browsermake eq "firefox">
<cfset size = "55">
</cfif>
<cfset onChange = "document.frmMain.submit1.disabled = true;setdisplayname(this,this.form.dummy);">
<cfif displayname EQ "">
<cfset size = "document.frmMain.submit1.disabled = true;setdisplayname(this,this.form.displayname);">
</cfif>
<cfinput type="file" name="File#thisUploader#" id="File#thisUploader#" size="#size#" onKeyPress="return false;" onchange="#onChange#">
`
and in my cfc the code is like this -
<cffile accept="image/*" action="upload" destination="#application.artworkfilepath#\bulkuploads\#session.loginname#\#form.category#\" filefield="form.File#thisUploader#" nameconflict="makeunique">
and if I dump - <cfoutput>
You uploaded #cffile.ClientFileName#.#cffile.ClientFileExt#
successfully to #cffile.ServerDirectory#.
</cfoutput>
<cfabort>
I get corrct things and no error.
But when i look into the folder there is nothing.
Anyidea? I have added the dump of cffile now. What do you make out of it?
cfform code is like this <cfform id="frmMain" name="frmMain" action="process_multi.cfm" enctype="multipart/form-data" target="_self" method="post">
do a fileExists() directly after the statement and let us know what that says...
you don't have a directorywatcher on the directory do you?
Your cffile nameconfict attribute is set to makeunique, which tells ColdFusion to rename the file to something new when it arrives at the server--if the file already exists.
However, you are using cffile.ClientFileName and cffile.ClientFileExt to refer to the file file--which maps to the unchanged file name as it was received during upload.
Change your code references to cffile.ServerFileName and cffile.ServerFileExt for the final renamed result.

How best to use the cffile to output the file ?
Also when i look at the DB, i am getting the file name as
"C:\ColdFusion8\runtime\servers\coldfusion\SERVER-INF\temp\wwwroot-tmp\qeq344.tmp"
How to correct it?
Is there any better way.

That is a temporary file name assigned to newly uploaded files. On your action page, you need to use cffile action="upload" ... to move that temporary file to the desired location. That will populate a structure called CFFILE with details about the uploaded file, such as CFFILE.serverFile and CFFILE.serverDirectory. (Or use the "result" attribute to output the details to whatever structure name you choose.)

the file ?
You cannot display binary files (like *.doc) with cfoutput. To display/download such files in a browser use cfcontent
