我正在尝试使用php将视频或图片上传到我的服务器。但是我不断收到错误，文件名似乎为空，我不明白为什么，代码不断执行显示错误的脚本，并且没有任何东西上传到我的文件夹
这是我的代码：
<div class="container" id="step2-video" style="display:none; margin-top:100px" >
<div class="row">
<div class="col-lg-4 col-md-offset-4">
<form id="video_uploader" action="ad_creator.php" method="post" enctype="multipart/form-data">
<div id="btn-upload-video">
<span class="file-wrapper btn ad-choice">
<input type="file" id="video-file-upload" name="video-file-upload" accept="video/mp4"/>
<span class="button">Choose a video</span>
</span>
</div>
<div id="video-preview" style="display:none" >
<span class="file-wrapper btn ad-choice">
<?php
?>
<input type="submit" name="upload_video" value="Submit" style="margin-left:auto" />
<span class="button">Comfirm</span>
</span>
</div>
</form>
</div>
</div>
</div>
<!--
Step 2 for pictures of the editor
-->
<div class="container" id="step2-picture" style="display:none; margin-top:100px" >
<div class="row">
<div class="col-lg-4 col-md-offset-4">
<form id="picture_uploader" action="ad_creator.php" method="post" enctype="multipart/form-data">
<div id="btn-upload-picture">
<span class="file-wrapper btn ad-choice">
<input type="file" id="picture-file-upload" name="picture-file-upload" accept="image/gif, image/jpeg, image/jpg, image/png"/>
<span class="button">Choose a picture</span>
</span>
</div>
<div id="picture-preview" style="display:none" >
<div id="imagePreview"></div>

<span class="file-wrapper btn ad-choice">
<input type="submit" name="upload_picture" value="Submit" style="margin-left:auto" />
<span class="button">Comfirm</span>
</span>
</div>

来自雷斯卡特，谢谢。我正在检查错误的文件输入，我正在检查$_FILES['image']['name']而不是$_FILES['picture-file-upload']['name']
尝试使用函数来执行这两项操作。需要注意的事项，您可能应该进行一些检查和平衡：
- 清理文件名以获得良好的度量。
- 包括绝对路径的文档根目录，或确保您具有正确的相对路径。
- 您可能需要检查上传文件夹是否存在，如果不存在，则进行上传。
- 检查上传
