In my Javascript I am assembling and array like so:
cachePHP = "'lat':'" + (Number(upDataItems[2])).toFixed(5)+"'";
cachePHP = cachePHP + ",'lon':'" + (Number(upDataItems[3])).toFixed(5)+"'";
cachePHP = cachePHP + ",'msec':'" + (parseInt(upDataItems[7])-parseInt(tz))+"'";
cachePHP = cachePHP + ",'spd':'" + (Number(upDataItems[0])).toFixed(1)+"'";
cachePHP = cachePHP + ",'hdg':'" + (Number(upDataItems[1])).toFixed(1)+"'";
dataCacheNew.push("{"+cachePHP+"}");
I add a varying amount of data to the array, could be 10 items, could be 100...I then shove this over to a PHP file. The PHP file is called from the Javascript like so:
"my.php?che="+JSON.stringify(dataCacheNew);
In the PHP, How can I grab the data so I can 'parse' it and post it to my database?
UPDATE 03/13: I still can't get this to work. Updated per suggestions below, and still...no workie!
My Javascript (jQuery):
var jsonData = new Array();
jsonData.push({
lat: Number(56.34).toFixed(2),
lon: Number(12.56).toFixed(2),
msec: Number(123456799000).toFixed(2),
spd: Number(4.2).toFixed(2),
hdg: Number(1.4).toFixed(2)
});
jsonData.push({
lat: Number(12.34).toFixed(2),
lon: Number(34.56).toFixed(2),
msec: Number(123456789000).toFixed(2),
spd: Number(1.2).toFixed(2),
hdg: Number(3.4).toFixed(2)
});
$.ajax({
url: 'insertCache.php',
type: 'POST',
data: "che="+JSON.stringify(jsonData),
dataType: 'json',
contentType: "application/json",
success: function(result) {
alert(result);
}
});
My PHP:
$cache = $_POST['che'];
writeData($cache,"insertCache.txt");
$cacheDecode = json_decode($cache);
writeData($cacheDecode,"insertCacheDecode.txt");
insertCache.txt:
[{\"lat\":\"56.34\",\"lon\":\"12.56\",\"msec\":\"123456799000.00\",\"spd\":\"4.20\",\"hdg\":\"1.40\"},{\"lat\":\"12.34\",\"lon\":\"34.56\",\"msec\":\"123456789000.00\",\"spd\":\"1.20\",\"hdg\":\"3.40\"}]
insertCacheDecode.txt COMPLETELY BLANK
what gives?
