[RESOLVED] What am i doing wrong here? Text document Help...

mbrown174

Hello,
I'm trying to create a small comments page for my website, the comments would be stored to a text document. So far I have them storing but each entry overwrites the other one. I know that by putting in a /n I could place eack comment on a new line, trouble is I'm not sure where to put it!

My Code So Far...
Comments.php
<?php
$myFile = "texts/comments.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, 710);
fclose($fh);

echo $theData;
?>
</p>
</div>
<p><strong>Post Comments Here </strong></p>
<FORM method="POST" action="process.php">
<p>
<textarea name="text" cols="50" rows="10"></textarea>
</p>
<p>
<INPUT type="submit" name="submit" value="submit"></p>
</FORM>
The above code is for my form and opening the text file for viewing...

Process.php
<?
$fn = "texts/comments.txt";
$content = stripslashes($_POST['text']);
$fp = fopen($fn,"w") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
echo "<meta http-equiv=\"refresh\" content=\"0; url=comments.php\" />\n";
?>
Above is the code that should store new entries in the text document...

Thanks in advance for any help!

Well... almost... it's actually \n.

Well, do you see where the $content variable is being set? You'll probably want to append a string after the stripslashes() command 😉

Also, you'll be adding a literal line break here if you use \n - so you won't actually see it on a new line in your browser. You'll have to use the HTML entity <br> (or the XHTML entity <br/> :p) there. You might want to add a linebreak after the entity as well, just so the file isn't all clumped on one line.

I dont mean to be spoon fed. But how would I set it out?

<?
$fn = "texts/comments.txt";
$content = stripslashes($_POST['text']"\n");
$fp = fopen($fn,"w") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
echo "<meta http-equiv=\"refresh\" content=\"0; url=comments.php\" />\n";
?>
I should probably research strings a bit more. Thanks for the help so far!

Use this instead

$fp = fopen($fn,"a") or die ("Error opening file in write mode!");

bradgrafelman

Ah yes, that's one mistake I didn't catch - the mode on your fopen() call. 'w' will open and truncate the file, meaning whatever you write is effectively overwriting the old data. 'a' is the append mode, which just adds data onto the end of the file.

As to your syntax, what you're wanting to do is concatenation - putting two separate strings together. See this man page for how it's done: [man]language.operators.string[/man]. Basically, you just use a period between each piece.

Also, I see you're trying to write just \n. You did read the part of my post that explained how that will not go to a new line in a browser (well, unless you use <pre> or some similar CSS style), right?

Houdini

This will work (at least each new entry is seperated with a line break in the browser).

$fn = "../texts/comments.txt";
$content = nl2br(stripslashes($_POST['text'])."\n");
$fp = fopen($fn,"a") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
echo "<meta http-equiv=\"refresh\" content=\"0; url=comments.php\" />\n";
?>

Have fun with it. It is now a simple kind of chat or shout box.

Hey, is there any way we can get a link to this and see it in action?

Sure I'll put one in later, I have to see if I can create a sort of filter to stop cursing now - I've seen someone ask this on the forums before, so it shouldnt be to difficult. Thanks again.

Hello again, I have a basic curse filter working. Trouble is I can only get it to filter one curse word.

The Code that works for filtering one curse word...
<?
$fn = "texts/comments.txt";
$content = nl2br(stripslashes($_POST['text'])."\n"."<hr>");
$oldWords = "shit";
$newWords = "s**t";
$content = str_replace ($oldWords , $newWords , $content);
$fp = fopen($fn,"a") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
echo "<meta http-equiv=\"refresh\" content=\"0; url=comments.php\" />\n";
?>

The Code that doesnt work for filtering multiple curses...
<?
$fn = "texts/comments.txt";
$content = nl2br(stripslashes($_POST['text'])."\n"."<hr>");
$oldWords = array( "[shit]","[fuck]");
$newWords = array( "[st]","[fk]");
$content = str_replace array($oldWords , $newWords , $content);
$fp = fopen($fn,"a") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
echo "<meta http-equiv=\"refresh\" content=\"0; url=comments.php\" />\n";
?>

my PHP knowledge is still very basic but I tried using an array for storing multiple curses. exactly what have i done wrong?

cahva

What the heck is this? 🙂

$content = str_replace array($oldWords , $newWords , $content);

Remove that "array" and it will work. To be more clear:

$content = str_replace($oldWords , $newWords , $content);

Also take off those [ and ] signs from those arrays. It would only replace the word if its written [shit] or [fuck]

Many Thanks

For anyone who needs it, the complete code for my very basic Comments page...
<?
$fn = "texts/comments.txt";
$content = nl2br(stripslashes($_POST['text'])."\n"."<hr>");
$oldWords = array( "shit","fuck","dick","bitch","bastard","cunt","piss","</script>");
$newWords = array( "st","fk","dk","bh","b**d","ct","p**s","No Javascript Allowed");
$content = str_replace ($oldWords , $newWords , $content);
$fp = fopen($fn,"a") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
echo "<meta http-equiv=\"refresh\" content=\"0; url=comments.php\" />\n";
?>
