I'm trying to write a simple weblog script, but I've encountered a
perplexing problem. I'm sure I'm overlooking something simple.
I'm trying to take <textarea> form input, parse it, and wrap it in <p> tags.
The problem is removing extra carriage returns. I'm sure there's a problem
with the "if ($sentence != ' ')", but I don't know what the right
conditional statement is. No matter what I put in there, it keeps
processing any extra blank lines and putting an extra pair of "<p></p>" tags
in. Granted, this doesn't effect the way the page is displayed. For
correctness sake, I'd rather not have them in there.
Here's the simple page I threw together to illustrate the problem:
<html>
<body>
<?php
if ($submit) {
$funk = explode("\n", $paragraph);
foreach ($funk as $key => $sentence) {
if ($sentence != ' ')) {
$funk[$key] = "<p>" . $sentence . "</p>\n";
echo $funk[$key];
}
}
} else {
?>
<p><form method="post" action="<?php echo $PHP_SELF?>">
Text:<textarea name="paragraph" rows="10" cols="40"></textarea><br>
<input type="submit" name="submit" value="Mangle This">
</form></p>
<?php
}
?>
</body>
</html>
Thanks in advance,
Chris
