How do you get it to pop up the "where do you want to save the file box" dialogue box? How can I save this file on my local box. Or, is it possible to directly read the content of file without saving it in my local box through coldfusion using cfftp or cfhttp? Using cfhttp, you can submit the form variables to the URL, and get back the data.
From there, you could save it, manipulate it in memory, or whatever. If you need to push the content to the client from CF, you can use cfheader and cfcontent to do so. Run it by hand once to see if it is really an excel file or an HMTL file with an "xls" extension, which is a common trick. If it is HTML, then it is gonna be a pain to read.
Then you can use cfspreadsheet CF9 to read the excel binary. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

For example, to tell ColdFusion to return the page using Japanese EUC character encoding, use the type attribute, as follows:.
If a file delete operation is unsuccessful, ColdFusion throws an error. Do not use this tag after the cfflush tag on a page, it has no effect or ColdFusion throws an error.
The following tag can force most browsers to display a dialog box that asks users whether they want to save the contents of the file specified by the cfcontent tag using the filename specified by the filename value. If the user selects to open the file, most browsers open the file in the related application, not the browser window. Some file types, such as PDF documents, do not use executable code and can display directly in most browsers.
To request the browser to display the file directly, use a cfheader tag similar to the following:. You can use any value for the filename part of the filename attribute, but the ext part must be the standard Windows extension for the file type. For file types that might contain executable code, such as Microsoft Excel documents, most browsers always ask before opening the document.
For these file types, the inline content disposition specification requests the browser to display the file directly if the user selects to open the file. For more information on character encodings, see the following web pages:. This list uses Java internal names, not the IANA character encoding names that you use in the SetEncoding charset parameter and other ColdFusion attributes and parameters.
For a complete list of media types used on the Internet, see www. When using cfabort, cflocation, or cfcontent tags, the OnAbort method is invoked instead on OnRequestEnd.

For example, use the following code to assign read permissions for everyone:. After a file upload is completed, you can retrieve status information using file upload status variables.
This status information includes data about the file, such as its name and the directory where it was saved. You can access file upload status variables using dot notation, using either file. Although you can use either the File or cffile prefix for file upload status variables, cffile is preferred; for example, cffile. The File prefix is retained for backward compatibility. Note: File status variables are read only.
They are set to the results of the most recent cffile operation. If two cffile tags execute, the results of the first are overwritten by the subsequent cffile operation. The following table describes the file upload status variables that are available after an upload:. Initial name that ColdFusion uses when attempting to save a file; for example, myfile.
Full name of the source file on the client system with the filename extension; for example, myfile. Size of the file that was overwritten in the file upload operation.
Empty if no file was overwritten. With the cffile tag, you can create application pages to manage files on your web server. You can use the tag to move files from one directory to another, rename files, copy a file, or delete a file.
The examples in the following table show static values for many of the attributes. However, the value of all or part of any attribute in a cffile tag can be a dynamic parameter. Note: Ensure that you include the trailing slash when you specify the destination directory. Otherwise, ColdFusion treats the last element in the path as a filename.
This rule only applies to copy actions. In addition to managing files on the server, you can use the cffile tag to read, create, and modify text files. As a result, you can do the following things:. You can use the cffile tag to read an existing text file. The file is read into a local variable that you can use anywhere in the application page. For example, you could read a text file and then insert its contents into a database, or you could read a text file and then use one of the string replacement functions to modify the contents.
You can use the cffile tag to write a text file based on dynamic content. For example, you could create static HTML files or log actions in a text file. Note: The form does not work until you write an action page for it see the next procedure.
Name Form. You can use the cffile tag to append additional text to the end of a text file; for example, when you create log files. Change the value for the action attribute from write to appendso that the file appears as follows:. Legal Notices Online Privacy Policy. Using cffile Search. You can use the cffile tag to work with files on the server in several ways: Upload files from a client to the web server using an HTML form Move, rename, copy, or delete files on the server Read, write, or append to text files on the server You use the action attribute to specify any of the following file actions: upload, move, rename, copy, delete, read, readBinary, write, and append.
The required attributes depend on the action specified. Uploading files File uploading requires that you create two files: An HTML form to specify file upload information An action page containing the file upload code The following procedures describe how to create these files.
