I am taking user input sending it to server using jQuery ajax...after inserting user values in database I am sending response back to client as JSON string as following
echo '{"success":"true","data":"'.nl2br($a).'","type":"text"}';
as user input can contain new line, I am using nl2br so that all new line characters are converted to <br> and also know that JSON doesnt support multi line, thats why I am using nl2br....but parsing is failing at client side
pls tell me what the reason and how can I solve it?
parsing code var obj = jQuery.parseJSON(data);
echo json_encode(array("success"=>"true","data"=>$a,"type"=>"text")
Use the php function json_encode rather then trying to set the encoding yourself. You'll save yourself a lot of trouble that way. http://php.net/manual/en/function.json-encode.php
nl2br() does not replace the line breaks, only inserts <br>
before them.
As such, \\n
is being returned and therefore creating invalid JSON.
You should use json_encode()
when creating JSON strings. For simplicity, you could simply use it on data
:
echo '{"success":"true","data":' . json_encode(nl2br($a)) . ',"type":"text"}';
You should be using json_encode, wich will generate a JSON string that contains \\r\\n
for line breaks. Then you will have to replace each \\r\\n
occurences by <br>
tags.
echo str_replace('\r\n','<br>', json_encode(array("success"=>"true","data"=>$a,"type"=>"text")));
