I am saving my images directly in the database (Yes I have read about that and know it's better to save the path to the image). The problem is selecting the image field which is a blob returns NULLto my JSON. I have alot read quite a few stackoverflow links of the same query but still not a clear explanation/ answer received has been able to help me. I have encoded using base_64 but when doing so nothing is showed on the webpage.
Would appreciate if I could be pointed in the correct direction.
This is part of my code:
header("Content-Type:application/json");
//select query
$rows = array();
while($r = mysqli_fetch_assoc($sth)) {
$rows[] = $r;
}
if (!empty($rows))
{
$encode = array("StudentsList" => $rows);
//$json_response=json_encode($encode);
$json_response=base64_encode($encode);
echo $json_response;
echo json_last_error(); //Returns 0
}
