Hi there,

I am passing following in html:
<a href=phpFilepath?action=tagClicked&uploadId=2 rel = 'tag' >associatedText</a>

now on clicking on associatedText I am getting uploadId in php and from that I am fetching server Path that is stored in database.

suppose my server path = "ftp://userName:Password@ftp.example.com/TempUpload/Doc/Case Studies for Uploading.doc"

this is giving me not readable result of the file.

Can you please tell me how can I open the file in readable manner??

So is the problem that you cannot read the file from the FTP server?

No I got the file in the same browser with not readable fonts that are like square, circle etc. But I want the same file in open another browser with the same formating that has been in the file located at the server.

If i understand correctly you want them to be able to, say, have the "save file" dialog pop up. If so you want:

header(<code><span class="string">'Content-Disposition: attachment; filename="[FILE NAME]"');</span></code>

<span class="string"></span>

No dear,

I want just the file from the server that is only readable. the user can not save it directly.
suppose there is a ".doc" file and the user click on it's link then he should read the content of that file from the window itself.

Then you are going to need the "Content-type: [content type]" header. You can get the value when it is first uploaded:

$fileType = $_FILES['NAME']['type'];

//This is an example of using this value.

str_replace("\n", "", $fileType); //Security
str_replace("\r", "", $fileType); //Security

header("Content-type: {$fileType}"); //Send Header

echo $File; //Echo the file down.

Hi,
Actually what I am doing is:
1> The user will upload a file to the server
2> I am storing that file information like, server path with file name and extension, associated text(show to the user by clicking on which it will show the file on that path that is stored for that text)
3> Now the another user wants to open that uploaded file so he will search by associated text and will get some link with them.
4> Now when he will click on some associated text, the path for that text will be there and the file should display over there or in another window to that user.

upto 3rd point is working properly but 4th point is not.
Hope you can get better idea from this what I want to do.

I am waiting for your reply. Smile | :)

Wit, now i think i know what the problem is: is it that you don't know how to get the file for the user?

Have you any idea how can I get the file from server and show it to the user as per its format???

Bradml6-Mar-07 18:34

6-Mar-07 18:34

Ok do you mean just send it to them as if they have requested it from the server normally or do you mean in a way that the browser will save it to disk?

I want that dialogbox that will ask the user to save or open the file he is asking for.

The dialogbox that is appears for normally we are downloading some attachment from the mail which asking to open file temporary or want to save it.

The code I gave you before (Content-disposition) will do that for you.

Its give me an error "Warning: Cannot modify header information - headers already sent" on following line,

header("Content-type: {$fileType}");

do you have any alternative??

Bradml6-Mar-07 19:50

Ok this error is because you have not started the document with the <?php tag.

Although this is a common mistake it is made by many people.

Make sure there is no blank space in the file before the php tag and make sure that you don't echo or print anything to the browser before the header function executes.

Well I have used only one php file for the whole application So php tags are there as per they should.

I just use cases for doing different things.

I wrote :
<a href=phpFilepath.php?action=tagClicked&uploadId=2 target='_blank' rel = 'tag' > associatedText</a>

And there is no echo after the linked text is clicked.

OK two problems that jump out at me from the scripts you sent is that you have a character before the first tag in the library and also you have a blank line at the end of it. Because of this it will send all headers down before you can modify them.

Ok I have been reading the function where you get data from the database. One thing that really strikes me is that you don't validate the data before you pass it to the database. This is incredibly important because otherwise people can execute any SQL commands they want (including stealing other people's files).

Please go to http://www.phpsec.org[^] to learn more.

I have now emailed you an updated copy of the script which should fix the problem you have but will not fix the security problem.
