Re: [PHP] appending to a file using ftp functions
Giulio wrote: Hi, I'm developing an application that uploads file to a server using http. the app calls a php on the server sending all the data just like a web form post.

Wanna do that to avoid possible problems with php temporary files max size. No problem on the client side ( is sends the form with some info and the firts chunk, waits for server response and then repost a form with succesive chunk of file, and so on ), and also on the php side should be quite easy to store a file with the first post, and keep on adding to it the subsequent chunks of file posted, at least using the filesystem functions. My problem is that I'm using, to make the system as general as possible, and make it work even on servers where php doesn't have write privileges, ftp functions instead of filesystem functions, and using ftp it seems that it's not possible to append to a file. I also thinked to use the fopen function with an ftp address, but reading the docs it says that fseek function ( to position the pointer at eof to go on appending ) may not work if the file is opened using ftp or http. Suggestion about this issue? ftp_put() has startpos parameter. I think you need to turn FTP_AUTOSEEK off, because you have only partial file. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] appending to XML file before closing tag
rantmode Hey - if you read my post a little more carefully you would see that I was bemoaning the effective passing of *SGML*. I was on a nostaligia trip. I am well aware that SGML is a bit of a complicated beheamoth, but it you have a decent SGML parser ( such as Omnimark or SP) you could do some really funky things. XML is a very cut down version of SGML that requires much simpler tools to process, but every now and again that simplicity will come back to bite you and make your life more difficult. This was one case of that. Most of the time I am quite happy to put up with the verbosity. /rantmode At 23:24 26/06/2002, Erik Price wrote: On Tuesday, June 25, 2002, at 08:42 PM, Brian White wrote: I was actually thinking about this the other day - every now and again I find my self yearning for SGML, where you could have just declared the wrapping element end tag omissable, and then you would never have to worry about it - basically the end of the file would imply the existence of the end tag (sigh ) Yes, but that makes parsing very difficult -- if you're expecting to find a closing tag, it should be there.

If you know for a fact that the ending tag for each file is consistent and always that same tag, here's an idea. Determine or specify the length of the ending tag (in other words /html would be a length of 7 [characters]). Now move your file pointer to (file's total characters - length) so that it is immediately before the ending tag. Append your data, then manually append the ending tag. If you will deal with varying ending tags, then you'll have to come up with a creative method for capturing them and storing them, then dynamically determining their length and do the same thing, then append the ending tag (whatever it may be). I would use regexes to do this part. Erik Erik Price Web Developer Temp Media Lab, H.H.

Ok this is an unusual problem, at least to a newbie like myself... I am
trying to develop a user form to select an image from a directory by

to be
able to do something which I am not entirely clear on where to start...
1- I need to have the selection append the file path to the selected
file...
i.e. http://localhost/images/file_name.jpg, so far it only puts
file_name.jpg into the database table.
If you already know that the file will always be in the same directory,
you could just prepend the string http://localhost/images/; to the
query result in your query --
SELECT CONCAT('http://localhost/images/', tablename.image_name) AS
image_name FROM tablename
Or, if each file may have a different path, check out the dirname()
function -- http://www.php.net/manual/en/function.dirname.php
I think that you will have to add http://virtualhost; in any case, as
this is a component of a URI and not a part of the file's path (and will
not be automatically generated by dirname() or any other function that I
know of).

So putting it into an UPDATE statement it would be something like this
right?

No, like this:
The table is named test_table
The column you want to add this to is named test_column
You are taking the data that test_column contains, and prepending
http://localhost/images; to the beginning of that data:
UPDATE test_table SET test_column = CONCAT('http://localhost/images',
test_table.test_column)
Warning: This command will change every single row in your table so that
'http://localhost/images' will be prepended before whatever data is
already in that row. You probably want to make ABSOLUTELY SURE that
this is what you want (are you sure you don't want a trailing slash in
that CONCAT function?). If you want to just test this out, or don't
want to apply this change to EVERY row, you can add a WHERE clause to
choose certain rows to update.
Keep in mind that test_column must be able to accommodate the new string
(so you might need to make it a bigger VARCHAR or something).
Good luck,
