i trying make app tracks location , upload database been working on project time on right track know do correct problem can 1 please help...how should set database app record username , lat , long , save database , retrieve can use google maps please me this...

is sql wrong

your execute line should be:

$q->execute(array($x, $y));

isn't ? input parameter should in form of array, supplied 2 parameters, 1 array, other 1 variable.

also, sql incorrect. should be:

update locations set x=?, y=? username = 'asd'
