Question

So I am trying to store user likes from facebook in database

$likes_json=json_encode($user->likes->data);
echo($likes_json);
$query = "INSERT INTO users VALUES (' ','".$likes_json."', NOW())";
$mysqli->query($query);

“echo” prints out the expected string (of length 56000 characters)

[{"name":"The Next Web","category":"Website","id":"106976563522"....

But nothing is being stored in Database. When I change $likes_json='some other string'; it works fines(it gets inserted in the database)

Coloumn for likes is of type “mediumtext“

Answer 1

You need to escape $likes_json using mysql_real_escape_string

Your query ends up looking like this

INSERT INTO users VALUES (' ','[{"name":"The Next Web","category":"Website","id":"106976563522"}]', NOW())

See why that wouldn’t work? What if the data contains a ‘ ?
