Question

我一直在为面料创建一个不同位置的小地图。我的目标是确保我可以将1,2,3和4（人）拖到一个位置（例如生产负责人）并将DIV的位置保存到MySQL数据库中。我想要一张全球地图，因此访问此页面的每个人都会看到相同的内容。

我为已经在数据库中的每个人（1,2,3和4）创建了不同的DIV。

我现在被困住了......有人能帮助我吗？

数据库连接并显示数据库中的人员：

function choosePerson() {
$servername = "";
$username = "";
$password = "";
$dbname = "";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT id, name, image, position FROM Persons";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
    // output data of each row
    while($row = mysqli_fetch_assoc($result)) {
        echo '<div class="boxPersons posLeft" id="'. $row['id'] .'">'. $row['id'] .'</div>';
    }
} else {
    echo "0 results";
}
}

Answer 1

// Move the box into the corresponding id.
// When you load your boxPersons have each 
// person an id column that matches what position they will be in.
$(".boxPersons").each(function(e){
  var target = $(this).attr("data-id");
  $("#"+target).append($(this));
});

$(".boxPersons").draggable({
  revert: 'invalid',
  containment: '.box',
  cursor: 'move'
});

$(".openSpots, .box-persons").droppable({
  accept: ".boxPersons",
  drop: function(event, ui) {
    var droppable = $(this);
    var draggable = ui.draggable;
    // Move draggable into droppable
    draggable.appendTo(droppable);
    draggable.css({
      top: '0px',
      left: '0px'
    });
  }
});

.box-content {
  display: flex;
}

.toPlan {
  width: 10%;

.overviewPlanning {
  flex: 1;
}

.box-persons {
