如何在 octobercms 中显示来自多个输入文件的图像

Question

我想在多输入文件中显示我上传的图片；输入文件位于以我的显示页面为目标的表单中：

<form method="POST" action="{{ 'etape_4'|page }}" accept-charset="UTF8"  enctype="multipart/form-data">
        <input type="hidden" name="_handler" value="onTest">
                {{form_token()}}
                {{form_sessionkey()}}



 Upload photo: <input  name="photo[]" type="file" id="photo" multiple="multiple"  />



<div class=" col-sm-offset-3 col-sm-9">

 <button type="submit" class="btn btn-default">Suivant</button>


</div>


</form>

这是显示页面：

title = "etape_4"
url = "/etape_4"
is_hidden = 0
==
<?php



function onStart()
{

    $this['file'] = new \System\Models\File;
     $this['file']->fromFile(Input::file('photo'));

}

?>
==
<ul>
{%for image in file%}

<li>

{{image.path}}

<img src="{{image.path}}">
{%endfor%}

</li>
</ul>

当我选择图像并提交页面时，出现此错误：

is_file() expects parameter 1 to be a valid path, array given

那么解决方案是什么？请帮助我！

看来你是uploading multiple files and treating them as single file Object

lets correct onStart method to support multiple files

function onStart()
{
    $files = [];
    $multipleFiles = Input::file('photo');
    foreach($multipleFiles as $singleFile) {
        $fileModel = new \System\Models\File;
        $fileModel->fromFile($singleFile);
        $files[] = $fileModel;
    }
    $this['file'] = $files;
}

Just replace your onStart code with this one it should work.
