Posting the value of a textarea with jquery

Answer 1

You might want to check out PHP htmlentities and htmlspecialcharacters.

Answer 2

Note: You are using jQuery.post() and setting your data as a $_GET parameters. It should be called like;

$.post("/php/getFile.php", { action: "write", file: file, newcfg: newcfg },
   function(data){
     alert("Data Loaded: " + data);
   });

You can keep your line breaks with a function like this:

function splitter($content) {
$content = str_replace(chr(10),'<br/>',$content);
$content = str_replace("<br/><br/><br/><br/>","<br/><br/>",$content);
return $content;
}

Which you run like:

$newcfg = splitter($newcfg);

And typoknig is right abouit special chars
