如何将多张图片添加到数据库中

Question

我正在尝试为横幅图像添加多个图像，而为画廊图像添加多个图像，但是当我尝试添加图像时，它给了我错误：

数组到字符串对话。

我想将一张图片添加到同一张表中，将其他图片添加到不同的表中，这样当我将记录显示到我的视图中时，我可以轻松地制作一张横幅图片。

如果有人在这方面帮助我，我将非常感激。 所以这是我的看法。

 <div class="col-lg-12">
     <label for="main image">Upload Main Image: </label><br>
     <input type="file" name="image_file">
 </div><br><br><br>
                                       
 <div class="col-lg-12">
     <label for="Image name">Upload Mutiple Images:</label><br>
     <input type="file" required name="image_name[]" multiple/><br>
 </div>
