simple comment form/guest book

[jacko310592]

the follwoing code is the very bsic stage of a comment form/guest book, but im stuck at the moment as i cannot get the file im saving the data to to stop rewriting over the data which is already stored on it.

 

<form method="POST" action="">
<input type="text" name="name" value=""><br/>
<input type="text" name="email" value=""><br/>
<textarea name="message" rows="5" cols="20"></textarea><br/>
<input type="submit">
</form>



<?php
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

$txtFile = "comments.txt";
chmod("comments.txt", 0777);
$txtFile = fopen($txtFile, 'w');
$stringData = "{$name}<br/> {$email}<br/> {$message}";
fwrite($txtFile, $stringData);
fclose($txtFile);
?>

 

i found on a site that "chmod("comments.txt", 0777);" is supposed to let php edit the file without over-writing it, but it is just over-writing it, can anyone think why this is happening?

 

thanks guys

its your opening modifier,

 

you are using $txtFile = fopen($txtFile, 'w');

 

notice the w?

 

fopen() @php.net

'r' Open for reading only; place the file pointer at the beginning of the file.

'r+' Open for reading and writing; place the file pointer at the beginning of the file.

'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

'a' Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.

'a+' Open for reading and writing; place the file pointer at the end of the file. If the file does not exist, attempt to create it.

'x' Create and open for writing only; place the file pointer at the beginning of the file. If the file already exists, the fopen() call will fail by returning FALSE and generating an error of level E_WARNING. If the file does not exist, attempt to create it. This is equivalent to specifying O_EXCL|O_CREAT flags for the underlying open(2) system call.

'x+' Create and open for reading and writing; place the file pointer at the beginning of the file. If the file already exists, the fopen() call will fail by returning FALSE and generating an error of level E_WARNING. If the file does not exist, attempt to create it.

hmm gotta remember to do the "Quote from:THE PHP.NET MANUAL" more often

oh, i cant believe i missed that XD

i guess 'a+' is the best to go with then
