How do I save a text file?

Hi all

I want to save the contents of a textarea within my webform as a text file .txt
on my webserver. In addition, I want to save it with the same file name as the
next autoincrement number in my sql table.(e.g. If I have 15 records in my table
then the next autoincrement number will be 16 when I add a new record and I want
the text file to be saved as 16.txt)

sadly this is far as I have got cos im not sure how to do either of the above.

<?php
$textfilecontents=$_POST['text'];
?>

Any help greatly appreciated

Regards
Dynamo

Hi Dynamo,

Wouldn't it be easier for you to store that text in the database itself?

That aside.

This is how to do that:
1) Get the next autoincrement.
(I have no clue about the excact syntax because you din't mention the
database.)

For now I take that you find that number and store it in $ai, ok?

2) Create a new file with the right name ($ai.txt).
to do this:
- go to www.php.net
- look for the function fopen. (And when you are there, you can find all I
write here too, better, with more examples)

resource fopen ( string filename, string mode [, bool use_include_path [,
resource zcontext]])

So:
$filename = $ai.".txt";
$dir = "/home/dynamo/myfiles/"; // adjust to where you want to save
$fullpath = $dir.$filename;
$handle = fopen ($fullpath, "w+");

// now write
fwrite($handle, $_POST["text"]);

// and be a nice and close:
fclose($handle);


It is all on www.php.net
This is a good startingpoint:

Please note that I didn't implement any errorhandling.
But you should.

If you're actually putting it into the table, you can get the ID by
calling mysql_insert_id() after inserting it into the table.

So something like this should work:

function insert_and_write($data) {
if (mysql_query("INSERT INTO `table` (fieldname) VALUES ('$data')",
$link)) {
$filename = mysql_insert_id().".txt";
$fp = fopen($filename, 'w');
fwrite($fp, $data);
fclose($fp);
return true;
}
return false
}

This will also prevent it from trying to write to the file if the INSERT
query fails. I haven't tested this, but I'm pretty sure mysql_query()
returns false if the query fails for some reason.
