使用 imageUrl 不显示图像，一切似乎都正确.PHP

Question

这是我的控制器中的功能

 public function singleEdit($propertyId){

  $property = $this->propertyModel->getPropertyById($propertyId);
  $image = $this->propertyModel->getImageByPropertyId($propertyId);
  $data = [
    'property' => $property,
    'image' => $image
  ];
  $this->view('adminPages/singleEdit', $data);
}

这是我模型中的函数

    public function getImageByPropertyId($propertyId){
    $this->db->query('SELECT imageId, imageName, imageUrl, propertyId, imageRank FROM images WHERE                                          propertyId = :propertyId');
    $this->db->bind(':propertyId', $propertyId);
    $results = $this->db->resultSet();
    return $results;
}

这是我的观点

如果我尝试通过在图像标签中输入 src 来显示图像；例如，它可以工作

<img src="<?php echo URLROOT . "/images/properties/188118_1596663122.jpg"; ?>">

一旦我尝试使用 imageUrl 显示图像将不会显示。 如果我在图像标签外显示 imageUrl，它会显示出来，但在图像标签内，则不会显示任何图像。

Answer 1

您在 imageUrl 中存储了什么？ 如果您使用 img 标签存储信息，那么您可以简单地通过 echo imageUrl 显示 或检查 imageUrl 实际存储的图像的完整路径，图像名称后跟扩展，然后标签将显示图像，否则提供保存图像的完整路径，如 img src="path/imagename.extension" 将显示图像
