Hi everybody!
I'm building a small ajax app which consists of only 3 php files.
index.php which contains all the app and has a couple of
links. When a
link is clicked an Ajax request is sent to the server (using
prototype)
to the
url central.php with only one parameter 'id'. Depending on that
parameter, central.php should look for the appropiate
content, in this
case link1.php.
Then I return a JSON object with the "things" that should be
updated on
index.php
So this is the pseudo-code:
index.php
<html>...
<body>
<a href="" onclick="[send the Ajax request using prototype
with the id =
1]>Link #1</a>
<div id="theUpdatableDIV"></div>
</body>
central.php
<html>...
<body>
<?php
[read the id parameter]
switch(id){
case 1: //which is the only case for now!!
//build the JSON object
$output = array("title" => "Link #1 Title!",
"content"=>file_get_contents("link1.php"));//here I read the
last file
which has the content to be updated asynchronously
return [the JSON object based on $output];
break;
}
?>
</body>
link1.php
<div>Welcome to the content of link #1 which was updated using <a
href=" ajax.org <http://ajax.org>">ajax</a></div>
the JSON object is formed ok, now, my problem is that
link1.php outputs
like this:
<div>Welcome to the content of link #1 which was updated
using <a
href="ajax.org <http://ajax.org>">ajax<\/a><\/div>
So at the moment I update the <div id="theUpdatableDIV">
element on
index.php, I get no "real" content, but a string with the
strange slashes.
I've tried:
stripslashes, ereg_replace, str_replace and strtr to
eliminate the
wierd slashes.
Can anybody tell how to do it right?
how are you building the json object?
i recommend
json_encode(utf8_encode($dataToEncode));
if youre using php5. if youre using php4, try this:
http://mike.teczno.com/JSON/JSON.phps
also, you might want to check out firebug for firefox. it will
let you
easily analyze the interaction between the client and server.
also, to verify that the json object youre generating is infact ok;
run it through here:

Hi Nathan,
I'm using php5, and I'm building the JSON object just like that,
with the json_encode.
The problem with using utf_encode apart from the original is that
I get the \n\r for each line in the file read.
Any suggestions?
Thanx
are you running windows?
im guessing those are newline characters in windows format that arent
getting interpreted correctly on the
client side. you might try stripping out the newline characters prior
to encoding the data.
$jsonOut = json_encode(utf8_encode(str_replace("\r\n", '',
$stringToEncode)));
also, what are you trying to encode? if you are encoding arrays or
objects (php that is) you will have to
utf8_encode all the elements of those complex datums prior to handing
them to json_encode() for
the final output.

Hi again Nathan,
well I actually did that before, using the str_replace to eliminate al
the windows \r\n, but the big problem isn't that
the HTML code is being escaped too.
I get something like <div>this is the content<\/div>
it seems like the '/' is being escaped, but I need it as HTML.
