editing a text file using a form

fumanshu

Wierd indentationans are occuring when I read a text file into the text area of a form. I'm attempting to write a CMS for a site WITHOUT using a db. Although I have access to a DB, I really want to crack this without resorting to the usual method - I do think it's a bit of an overkill using up server resources if only simple page editing is required.

My code in the form looks like this:

$fp = fopen("/text/text_1.txt","r");

while (!feof($fp))
{
$text_1 = fgets($fp,100);
echo $text_1; ?>

}

fclose($fp);

?>
</textarea>

When outputed in browser, test text looks similar to:

==============================

	hello. this is a test

==============================

even though if I view the actual text file directly in the browser, it looks fine.

Has anyone seen this problem before?

BTW, my php script to write to the text file is:

$fp = fopen("/text/text_1.txt","w");

flock($fp,2);

$text_1 = trim($text_1);

fwrite($fp, $text_1);

flock($fp,3);

echo "text updated";

try to eliminate blanks and line breaks within the <textarea> tags which do not pertain to the text that is to be displayed.

the textarea part should be no more than this:

and you'll get rid of a lot of unwanted spaces.

Thanks for that, it seems to have cleared up the spaces issue - however I'm now getting a new text area box for each line. I know that's because it's looping and re-creating the text box for each line it reads - but what is the best way of reading a text file into a Form. Is this kind of method not recommended?

My new code looks like this:

$fp = fopen("/text/text_1.txt","r");

while (!feof($fp))
{
$text_1 = fgets($fp,100);

<?
}

	fclose($fp);

Try doing it this way maybe

<?
if (file_exists("/text/text_1.txt")){
$filesize = filesize("/text/text_1.txt");
$file = fopen("/text/text_1.txt", 'r');
$text = fread($file,$filesize);
fclose($file);
?>
<textarea name="text_1" cols="43" rows="10"><? echo $text; ?></textarea>
<?
}else{
echo("error");
}
?>

That even gets you a handy error checking routine added in.

Or if you need to read line by line (like you are searching each line for something you can do it like this:

<?
if (file_exists("/text/text_1.txt")){
$text_1 = "";
while (!feof($fp))
{
$text_1 .= fgets($fp,100);
}
fclose($fp);
?>

Basically all I did was change:

$text_1 = fgets($fp,100);

$text_1 .= fgets($fp,100);

The .= opperator will append the new info to the end of the string. I also move the html outside of the while loops so that you don't get multiple textarea's.

cool - thanks very much, that seems to have solved it....
