php - Multiple checkbox database insert with mysql prepare -

-

i have checkboxes generated code:

while($row = $result->fetch_assoc()) {     echo "<input type='checkbox' name='branch[]' value='".$row['id']."'> ".$row['name']."<br>"; }

and need insert value of every checkbox in mysql database. code have inserts every checkbox $member_id, $branch inserted 0. doing wrong?

$sql = "select id members email='$email'"; $result = mysqli_query($mysqli,$sql); $row = mysqli_fetch_array($result,mysqli_assoc); $member_id = $row["id"]; $checked_arr = $_post['branch']; $branch_count = count($checked_arr); ($i = 0; $i < $branch_count; $i++) {     if ($insert_stmt_branch = $mysqli->prepare("insert members_branch (member, branch) values (?, ?)")){              $insert_stmt_branch->bind_param('ss', $member_id, $branch);          if (! $insert_stmt_branch->execute()) {             echo "error: branch insert";         }     } }

at start of loop, forgot add:

$branch = $checked_arr[$i];

also, don't have verify query looking email address returns value. if no account found, $member_id value blank.
