Update txt file with PHP

[gilgimech]

What I'm tying to do is update a txt file using php.

 

the form:

<?php 
$file=fopen("news.txt","r") or die("Cannot open"); 
fclose($file); 
?> 

<form action="../includes/news_update.php" method="post">
<textarea rows="25" cols="40" name="content">
<?php echo $file ?>
</textarea><br>
<input type="submit" value="Submit"> 
</form>

 

update_news.php:

<?php
$content = $_POST["content"]; 
$file=fopen("news.txt","w") or die("Cannot open");
fwrite($content); 
fclose($file);  
?>

 

what I want to happen is the text from the file to populate the form field.

 

Edit the field then post it to the file.

 

I can't seem to get any of it to work.

Your problem is that fopen does not return the content of the file, so $file won't contain what you're expecting. Instead to you need to use fread. If you want to get the full content of the file you can do something like this:

 

<?php 
$fp = fopen("news.txt","r") or die("Cannot open");
$file = fread($fp, filesize('news.txt'));
fclose($fp); 
?>

 

The problem with your updating is that for fwrite you need to pass the resource returned by fopen ($file, in your case).

 

<?php
$content = $_POST["content"]; 
$file=fopen("news.txt","w") or die("Cannot open");
fwrite($file, $content); 
fclose($file);  
?>

I tried what you suggested now I get the error

 

Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/netgame2/public_html/pages/site_news.php on line 3

Well then that means your news.txt file contains nothing. To fix this before reading from the make sure there's actually something to read, like so:

 

<?php
if(($filesize = filesize('news.txt')) > 0)
{
    $fp = fopen("news.txt","r") or die("Cannot open");
    $file = fread($fp, $filesize);
    fclose($fp);
}
?>

My file size is 1.287k and there is something in it.

 

I replaced the code and the error is gone but nothing there is nothing in the textfeild.

 

The news section here uses the same txt file.

Do you have the path correct?

Yep it's in the same dir as the form
