如何通过PHP开发SuiteCRM的客户服务功能

<?php
  if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // 获取表单提交的数据
    $customerName = $_POST['customer_name'];
    $description = $_POST['description'];
    $priority = $_POST['priority'];

    // 创建新的客户服务记录
    $service = new Service();
    $service->name = $customerName;
    $service->description = $description;
    $service->priority = $priority;
    $service->save();
  }
?>

<form method="POST" action="">
  <input type="text" name="customer_name" placeholder="客户名称">
  <textarea name="description" placeholder="问题描述"></textarea>
  <select name="priority">
    <option value="Low">低优先级</option>
    <option value="Medium">中优先级</option>
    <option value="High">高优先级</option>
  </select>
  <button type="submit">提交</button>
</form>

<?php
  // 获取服务ID
  $serviceId = $_GET['id'];

  // 获取指定服务的详细信息
  $service = Service::retrieve($serviceId);

  // 处理表单提交
  if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // 获取表单提交的数据
    $description = $_POST['description'];
    $priority = $_POST['priority'];

    // 更新客户服务记录
    $service->description = $description;
    $service->priority = $priority;
    $service->save();
  }
?>

<form method="POST" action="">
  <textarea name="description"><?php echo $service->description; ?></textarea>
  <select name="priority">
    <option value="Low" <?php if ($service->priority === 'Low') echo 'selected'; ?>>低优先级</option>
    <option value="Medium" <?php if ($service->priority === 'Medium') echo 'selected'; ?>>中优先级</option>
    <option value="High" <?php if ($service->priority === 'High') echo 'selected'; ?>>高优先级</option>
  </select>
  <button type="submit">保存</button>
</form>

<?php
  // 获取服务ID和联系人ID
  $serviceId = $_GET['service_id'];
  $contactId = $_GET['contact_id'];

  // 创建服务和联系人的关联
  $service = Service::retrieve($serviceId);
  $service->contacts->add($contactId);

  // 获取服务关联的联系人列表
  $contacts = $service->contacts->get();
?>
