[FX.php List] Keeping Carriage Returns in Textarea submissions

[Steve Winter]

Hi Jonathan and Kevin, 

I think Kevin, that function will work fine for half of Jonathan's
requirements, the 'post the data back on the web page' (though wouldn't 

	echo '<p>'.nl2br($theData).'</p>';

have just the same result...?)

However for the other half of the requirements, if you use that function in
a textarea to allow editing Jonathan, then it's going to display <p>, <br />
and </p> tags within that textarea, then store those back in the db, then
end up in something of a mess next time it gets displayed...

For your text area you should just be able to use echo the data straight
into the text area and the newline characters stored in FMP will be rendered
out giving the correct display in the text field...

Cheers
Steve

Hi Johnathan,

Try this out:

// function to replace line breaks in FM output with <br /> or <p> elements

function formatDesc($input)
{
$br = chr(10); // single line feed character (LF)
$p = "<br />\n<br />\n";
$badChars = array($p, "& ");
$goodChars = array("</p>\n\t\t<p>", "&amp; ");
$text = str_replace($br, "<br />\n", $input); // replace LF with <br />

$description = str_replace($badChars, $goodChars, $text);
echo "<p>" . $description . "</p>\n";
}

Modify it as you need to!
