Invalid MIME or extension 4. File already exists. The name of the variable in which the file upload errors will be stored. Errors will be populated in the specified variable name when continueOnError is true.
After the file upload is completed, this tag creates an array of structures that contains upload failure information for each upload failure. After a file upload is completed, you can get status information using file upload parameters. To refer to parameters, use either the cffile prefix or, if you specified an alternate name in the result attribute, the name you specified there.
For example, if you did not specify a name in the result attribute, access the fileExisted parameter as cffile. If you set the result attribute to myResult, however, access fileExisted as myResult. Status parameters can be used anywhere that other ColdFusion parameters can be used.
The result attribute allows functions or CFCs that get called from multiple pages at the same time to avoid overwriting the results of one call with another. The file prefix is deprecated, in favor of the cffile prefix. Do not use the file prefix in new applications. This variable includes the file length plus the length of any other request content. File status parameters are read-only. They are set to the results of the most recent cffile operation.
If two cffile tags execute, the results of the second overwrite the first, unless you have specified a different result variable in the result attribute. For information on scope variables, see Evaluating the results of a file upload below.
Note: This example performs no error checking and does not incorporate any security measures. Before deploying an application that performs file uploads, ensure that you incorporate both error handling and security. For more information, see Securing Applications and Handling Errors.
When you save a file to the server, a file with the same name could exist. To resolve this problem, assign one of these values to the nameConflict attribute of the cffile tag:.
For some applications, you could want to restrict the type of file that is uploaded, for example, to not accept graphic files in a document library. You use the accept attribute to restrict the type of file that you allow in an upload. When an accept qualifier is present, the uploaded file MIME content type must match the criteria specified or an error occurs.
The accept attribute takes a comma-separated list of MIME data names, optionally with wildcards. The browser determines the file MIME type. Other browsers and earlier versions might ignore these associations.
You can restrict the file types, as demonstrated in the following examples. The following cffile tag saves an image file only if it is in the GIF format:. In Windows, you specify file attributes using attributes attribute of the cffile tag.
In UNIX, you specify file or directory permissions using the mode attribute of the cffile or cfdirectory tag. In UNIX, you can individually set permissions on files and directories for each of three types of users' owner, group, and other.
You use a number for each user type. This number is the sum of the numbers for the individual permissions allowed. Values for the mode attribute correspond to octal values for the UNIX chmod command:. You enter permissions values in the mode attribute for each type of user: owner, group, and other in that order. 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. I have a webform where users upload a. TXT file that gets saved to the server.
I have tried using a whole load of combinations - with and without the sign- but it simply doesn't work. Do any of you guys know what I am missing? I could have sworn I tried that one I am reading a. TXT file and parsing out the data that is tab-delimited. Is there a way for me to just looping from the 2nd row of data? The first row of data is the column headers which of course I am not concerned about because they are always the same in every file.
Can you just ignore the first line within your loop? I did end up writing a loop to ignore the first line. Since I did not want to modify the original data files, I think skipping the first line will work for now. Can anyone suggest me using other than cffile tag to write a file.
Because in server they restricted me to access these tags for security reason. Kindly advice me. I have a big text file which is K with over K records. It seems that ColdFusion refuse to read the file into a variable becasue the size. I am using the variable as a temp file, then parse into fields. Not successful. Is the page breaking on the file read? Or the subsequent parsing into fields? It should be able to read the file in, no problem - string data doesn't take up too much RAM.
String manipulation, however, depending on how you are doing it, might be the culprit. I am sorry, I am not sure what you are asking? Are you trying to read an uploaded file without saving it to the server's file system? It's a shame that you can use the "delimiter" attribute when cfloop-ing over a file. We were having timeout issues reading in a very large file, and it doesn't use the new line as the delimiter.
I ended up chopping the file into smaller files when I created it, and just read in each small file. You could use that or whatever you need to specify your desired delimiter. Thanks for the reply. Yep, I tried cffile read but the file is about mb, so I crash the JVM with an out-of-memory exception. I was hoping that with cfloop file I could use a that as a file pointer and not have to read the entire file into memory.
I have a local file that the user is browsing to and selecting that I wanted to parse and save in DB. I have something like this:. I think you can get the binary data from the form post I think you start to add a lot of complexity in parsing the form delimiters if you want to handle this manually. Once you upload the file, it gets saved, regardless, to the temp directory.
I believe, if you want, you can get the TMP file path from the form field itself, if you just want to read the file in that way?
If you have the full path to a file, you should be able to strip off the actual file name using getFileFromPath :. That was the idea. The getFileFromPath returns a " I'm not sure how to extract the actual file name when the user upload the file from their local machine. That's odd. Typically, you only see. I am not sure what process you have in place that is creating tmp files. Once it gets saved on the server, however, I don't think there's any way to get the original file name - you might have to augment whatever process saves the file in the first place.
If "main. With the CF9 admin setting "Cache Template In Request" you may get old results, because as you say, the content of the file is parsed.
First, I would just point out that that behavior you're seeing when "Cache Template In Request" is enabled is really to be expected.
Indeed, it's the very point of the new in 9 option: to tell CF NOT to check if a referenced file has changed after checking it the first time it's used within a request. Second, just to be technically accurate, it's not about the file being "parsed", though. It's just about CF looking to see if the update date of the file has changed.
With this new setting, it does it only once. Third, as for the "trusted cache", while you call it "worse", that's just really another dimension to this same issue.
So the new feature in 9 is kind of a compromise solution: it allows CF to pick up a change to a file between different requests, but it stops CF checking for the file update WITHIN a single request. I wouldn't see either of these as bad things, just different, and things that we do want to understand.
And it's great when they come up in blogs like this, or in mailing lists, as a chance to bring them to people's attention again, so thanks for bringing them up. And yes, as you say, the bottom line is that it is indeed one more reason one should not use CFINCLUDE to read in files, when there are many other options, and they aren't susceptible to these issues as you note. Viewed times. Using CF9, I want to write output to a csv file for user download.
Thanks in advance for the assistance. Improve this question. GaryV58 GaryV58 1 1 1 bronze badge. The data rpt. You should probably avoid encoding rpt. Thanks Alex, the encoded data was indeed legacy data stored in the database.
After cleaning up the data, the export is working as expected. Add a comment. Active Oldest Votes.
