Php 多类型后积垢

我想用php创建具有多个部分和数据类型的表单。例如： 输入文本（名称、标题、说明等） 输入图像（标题\图像） 输入多个图像（滑块）

重点是我想用php在一个页面中创建大量数据，包括上传文件。 在post方法中，我尝试使用标准逻辑，使用if-else逻辑逐个上传图像，使用大量if-else逻辑和不同的名称，并将其插入数据库的每个字段（一字段数据库中的一个字段）huft

对于编辑，我手动尝试，与post方法相同，对每个字段使用if-else。例如：

if($_FILES['imghead']['size']!=0){
 // run upload method
}
if($_FILES['slider1']['size']!=0){
 // run upload method
}
if($_FILES['slider2']['size']!=0){
 // run upload method
}
if($_FILES['slider3']['size']!=0){
 // run upload method
}
// etc

但问题是，我认为我的方法不是很好，它不是很有效，我必须写很多代码，并用if-else逻辑逐一检查它们

我的问题: 你知道如何将我的逻辑优化为真正简单的代码吗？特别是积垢

我尝试过grocerycrud，但我需要更多功能，如多图像上传

有一种方法可以使用grocerycrud实现多图像上传，在控制器中，您需要为所需的每个上载字段指定一个不同的名称方法，然后只需将main方法复制粘贴到credge_CRUD.php文件中，并将名称更改为您指定的名称

控制器代码：

$crud->set_field_upload('file1','assets/uploads');
$crud->set_another_field_upload('file2','assets/uploads');

这是您需要复制的代码，（路径：htdocs\app\u name\application\libraries\groundry\u CRUD.php）

只需将其粘贴到下面，并使用控制器中指定的相同名称更改函数名：

public function set_another_field_upload($field_name, $upload_dir = '')
{
    $upload_dir = !empty($upload_dir) && substr($upload_dir,-1,1) == '/'
                    ? substr($upload_dir,0,-1)
                    : $upload_dir;
    $upload_dir = !empty($upload_dir) ? $upload_dir : 'assets/uploads/files';

    /** Check if the upload Url folder exists. If not then throw an exception **/
    if (!is_dir(FCPATH.$upload_dir)) {
        throw new Exception("It seems that the folder \"".FCPATH.$upload_dir."\" for the field name
                \"".$field_name."\" doesn't exists. Please create the folder and try again.");
    }

    $this->upload_fields[$field_name] = (object) array(
            'field_name' => $field_name,
            'upload_path' => $upload_dir,
            'encrypted_field_name' => $this->_unique_field_name($field_name));
    return $this;
}

实际上，您可以在表单中使用slider[]而不是slider1,2,3，然后可以使用foreach（$_FILES['slider']作为$fileInfo）{…}

public function set_field_upload($field_name, $upload_dir = '')
{
    $upload_dir = !empty($upload_dir) && substr($upload_dir,-1,1) == '/'
                    ? substr($upload_dir,0,-1)
                    : $upload_dir;
    $upload_dir = !empty($upload_dir) ? $upload_dir : 'assets/uploads/files';

    /** Check if the upload Url folder exists. If not then throw an exception **/
    if (!is_dir(FCPATH.$upload_dir)) {
        throw new Exception("It seems that the folder \"".FCPATH.$upload_dir."\" for the field name
                \"".$field_name."\" doesn't exists. Please create the folder and try again.");
    }

    $this->upload_fields[$field_name] = (object) array(
            'field_name' => $field_name,
            'upload_path' => $upload_dir,
            'encrypted_field_name' => $this->_unique_field_name($field_name));
    return $this;
}

public function set_another_field_upload($field_name, $upload_dir = '')
{
    $upload_dir = !empty($upload_dir) && substr($upload_dir,-1,1) == '/'
                    ? substr($upload_dir,0,-1)
                    : $upload_dir;
    $upload_dir = !empty($upload_dir) ? $upload_dir : 'assets/uploads/files';

    /** Check if the upload Url folder exists. If not then throw an exception **/
    if (!is_dir(FCPATH.$upload_dir)) {
        throw new Exception("It seems that the folder \"".FCPATH.$upload_dir."\" for the field name
                \"".$field_name."\" doesn't exists. Please create the folder and try again.");
    }

    $this->upload_fields[$field_name] = (object) array(
            'field_name' => $field_name,
            'upload_path' => $upload_dir,
            'encrypted_field_name' => $this->_unique_field_name($field_name));
    return $this;
}
