将2个不同的数组值插入数据库不起作用

Question

I'm trying to insert 2 values from arrays into a database. There's nothing wrong with the connection, the fields where $fullArr and $thumbArr get inserted are longtexts, and when I try to insert 1 array value it works fine ($fullArr or $thumbArr). As soon as both arrays get used in the query it stops working.

The values in the arrays are data-urls.

private function submitPhoto() {

global $database;

$projectid = $_POST['projectid'];
$fullArr = $_POST['fullArr'];
$thumbArr = $_POST['thumbArr'];

$count = 0;

foreach($thumbArr as $key) {

// Insert Thumb

$database->query("INSERT INTO `photo` (photoid, projectid, dataurlfull, dataurlthumb) VALUES('', '" . $projectid . "', '" . $fullArr[$count] . "', '" . $key . "')");

$count++;
}
}

Answer 1

Try changing the query:

$database->query("INSERT INTO `photos` (photoid, projectid, dataurlfull, dataurlthumb) VALUES('', '$projectid', '$fullArr[$count]', '$key')");
