receiving newline inside a json object - php

Question

i am trying to bring a set of texts from a PostgreSQL database (field type is text) with ajax into my webpage. The problem i encouter is the newline, it works great when there is no newlines into the text in database, but when i use new lines in the text inside database, the json doesnt give me the data it stored.
function selectCalendarEvents(user_id, event_datestart, event_datestop, callback) {
var request;
if(window.XMLHttpRequest)
request = new XMLHttpRequest();
else
request = new ActiveXObject("Microsoft.XMLHTTP");
request.onreadystatechange = function() {
if (request.readyState == 4 && request.status == 200) {
if(request.responseText.substr(0, 6) == "error ")
alert(errorName[request.responseText.substr(6)]);
else {
jsonCalendarEvents = $.parseJSON(request.responseText);
selectEvents(user_id, event_datestart, event_datestop, callback);
}
}
}
request.open("GET", "php/calendar.php?action=selectCalendarEvents&user_id=" + user_id + "&event_datestart=" + event_datestart + "&event_datestop=" + event_datestop, true);
request.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");
request.send();
}
this is my javascript function which requests the data set
if($action == "selectCalendarEvents") {
$user_id = $_GET["user_id"];
$event_datestart = "'" . $_GET["event_datestart"] . "'";
$event_datestop = "'" . $_GET["event_datestop"] . "'";
require_once("connect.php");
$query = "SELECT event_id, event_name, event_datestart, event_datestop, event_timestart, event_timestop, calendar_events.calendar_group, calendar_color, event_info FROM calendar_events LEFT JOIN calendar_calendars ON calendar_events.calendar_group = calendar_calendars.calendar_group WHERE user_id = " . $user_id . " AND calendar_show = true AND event_datestart <= ". $event_datestop . " AND event_datestop >= " . $event_datestart;
$result = pg_query($connect, $query);
if(!$result)
die("error 1"); // query error
$comma = '';
$json = '{"events":[';
while ($row = pg_fetch_row($result)) {
$json .= $comma . '{';
$json .= '"event_id":"' . $row[0] . '",';
$json .= '"event_name":"' . $row[1] . '",';
$json .= '"event_datestart":"' . $row[2] . '",';
$json .= '"event_datestop":"' . $row[3] . '",';
$json .= '"event_timestart":"' . $row[4] . '",';
$json .= '"event_timestop":"' . $row[5] . '",';
$json .= '"calendar_group":"' . $row[6] . '",';
$json .= '"calendar_color":"' . $row[7] . '",';
$json .= '"event_info":"' . $row[8] . '"';
$json .= '}';
$comma = ',';
}
$json .= ']}';
echo $json;
}
this is my php which returns the dataset. If row[8] aka event_info stores text with newlines in it .. when i try to populate my calendar with the events, it seems the json doesnt store any data in it or smt like that.

Answer 1

I found out that i should replace \r\n with <br/> and it will work. im using like this replace(/\r\n/g, "<br/>") when i give the response string to json
jsonCalendarEvents = $.parseJSON(request.responseText.replace(/\r\n/g, "<br/>"));
