problem with 'edit this page' script

[JamesGecko]

I have this simple 'edit this page' script that won't work. I don't know why. I have tested the first two modules of code and they seem to work without any problem.


<?php
print "<h2>Edit this page</h2><p>";
//load up the text
$fp = fopen("./pinboard.txt", "r");
$content = fread($fp, filesize('./pinboard.txt'));
fclose($fp);
print "<pre>$content</pre><p>";
if (isset($_POST[content])) {
//write back the text
$fp = fopen("./pinboard.txt","w");
fwrite($fp, $_POST[content]);
fclose($fp);
}
//get a text box up for input
<form action=$_SERVER['PHP_SELF'] method=POST>
print "<textarea rows=5 cols=20 name=content wrap=physical>Text</textarea><br>";
<input type=submit>
</form>
?>

oops >_>

<?php
print "<h2>Edit this page</h2><p>";
//load up the text
$fp = fopen("./pinboard.txt", "r");
$content = fread($fp, filesize('./pinboard.txt'));
fclose($fp);
print "<pre>$content</pre><p>";
if (isset($_POST['content'])) {
//write back the text
$fp = fopen("./pinboard.txt","w");
fwrite($fp, $_POST['content']);
fclose($fp);
}
//get a text box up for input
<form action=$_SERVER['PHP_SELF'] method=POST>
print "<textarea rows=5 cols=20 name=content wrap=physical>$_POST['content'];</textarea><br>";
<input type=submit>
</form>
?>

okay, lets have a look at your code here:

<form action=$_SERVER['PHP_SELF'] method=POST>
print "<textarea rows=5 cols=20 name=content wrap=physical>$_POST['content'];</textarea><br>";
<input type=submit>
</form>

Why do you have the semicolon after the post variable?
The semicolon emplies that it is at the end of something which is to be executed.

if (something) {
do(something);
}

You have two ways of echoing a variable inside a form:

<form action=$_SERVER['PHP_SELF'] method=POST>
echo "<textarea rows=\"5\" cols=\"20\" name=\"content\" id=\"content\" wrap=\"physical\">{$_POST['content']}</textarea><br />";
<input type=submit>
</form>

Or:

<form action=$_SERVER['PHP_SELF'] method=POST>
<textarea rows="5" cols="20" name="content" id="content" wrap="physical"><?=$_POST['content']?></textarea><br />
<input type=submit>
</form>

ps. I might have given you some typo's here, since it's early in the morning.

<form action=$_SERVER['PHP_SELF'] method=POST>
<textarea rows="5" cols="20" name="content" id="content" wrap="physical"><?=$_POST['content']?></textarea><br />
<input type=submit>
</form>

Wouldn't that have to be

<form action=[red]<?=[/red]$_SERVER['PHP_SELF'][red]?>[/red] method=POST>
<textarea rows="5" cols="20" name="content" id="content" wrap="physical"><?=$_POST['content']?></textarea><br />
<input type=submit>
</form>

Also, you should put quotes around your html attributes.

ah, I didnt see that he had the PHP_SELF there.

you can cheat that one, by just putting ?foo in the action, so it will submit to self.
