I'm having a strange problem when retrieving JSON formatted text. I use jQuery post
to send some data (also JSON formatted) to the server (running PHP) which works fine. Then, when I request the same data from the server using jQuery get
, the callback method never executes. This only occurs when the data is JSON formatted and the data contains a line break. When I don't use JSON formatting it works fine. What baffles me is that there are no problems with uploading the data.
Uploading code: (works)
$.post("ajax/contents_ajax.php", { 'title': caption, 'text': frameText().getContent(), 'image_id': img }, //Callback
Download code: (doesn't work with line breaks)
$.get("ajax/contents_ajax.php", { 'get_item': id }, function (data){ //Never gets executed if data contains line breaks } ,'json');
The whole problem stems from the fact that the TinyMCE rich text editor seems to insist on inserting line breaks everywhere, even though I enabled the option
remove_linebreaks : true
I do prefer to have line breaks, but not if they break my code. Can anyone tell me what the problem is here, and perhaps how I can encode the linebreaks on the server with PHP?
While the suggestions to replace '\n'
with ''
did not work, it was close to the right solution. This code removed the offending characters:
function parse($text){ $parsedText = str_replace(chr(10), "", $text); return str_replace(chr(13), "", $parsedText); }
JSON does not allow real line-breaks. You need to replace all the line breaks with \n .
In JSON object make sure that you are having a sentence where you need to print in different lines. Now in-order to print the statements in different lines we need to use '\\n' (backward slash). As we now know the technique to print in newlines, now just add '\\n' wherever you want.
JSON Syntax RulesData is in name/value pairs. Data is separated by commas. Curly braces hold objects. Square brackets hold arrays.

If you would like to keep the line breaks, you might try:
function parse($text) { // Damn pesky carriage returns... $text = str_replace("\r\n", "\n", $text); $text = str_replace("\r", "\n", $text); // JSON requires new line characters be escaped $text = str_replace("\n", "\\n", $text); return $text; }
