php - Laravel 验证来自 HTML 表单数组的多个图像输入

Question

我有以下 HTML 格式的字段，

<div class="col-md-6"><input type="file" name="images[]"></div>
<div class="col-md-6"><input type="file" name="images[]"></div>
<div class="col-md-6"><input type="file" name="images[]"></div>
<div class="col-md-6"><input type="file" name="images[]"></div>
<div class="col-md-6"><input type="file" name="images[]"></div>
<div class="col-md-6"><input type="file" name="images[]"></div>

当我提交表单时，我会在 PHP 中获得 images[] 数组。我正在使用 Laravel 框架进行表单验证。我一直在使用验证器和规则。但我想将所需和最大大小的规则应用于上述数组中的每个图像。谢谢。

这是我的图像验证的示例代码：

// Handle upload(s) with input name "files[]" (array) or "files" (single file upload)

if (Input::hasFile('files')) {
    $all_uploads = Input::file('files');

    // Make sure it really is an array
    if (!is_array($all_uploads)) {
        $all_uploads = array($all_uploads);
    }

    $error_messages = array();

    // Loop through all uploaded files
    foreach ($all_uploads as $upload) {
        // Ignore array member if it's not an UploadedFile object, just to be extra safe
        if (!is_a($upload, 'Symfony\Component\HttpFoundation\File\UploadedFile')) {
        continue;
        }

         $validator = Validator::make(
            array('file' => $upload),
            array('file' => 'required|mimes:jpeg,png|image|max:1000')
         );

        if ($validator->passes()) {
            // Do something
        } else {
            // Collect error messages
            $error_messages[] = 'File "' . $upload->getClientOriginalName() . '":' . $validator->messages()->first('file');
        }
     }

    // Redirect, return JSON, whatever...
    return $error_messages;
} else {
    // No files have been uploaded
}
