使用 php 上传到服务器后图像大小显示为零字节
Image size showing Zero byte after uploading on server using php
我正在使用 croppie 插件裁剪图像,效果很好。图像存储在我的文件夹中,图像大小显示为零 bytes.It 在本地主机上运行良好,但在服务器上运行不正常。你愿意帮我吗?
<form action="process.php" id="form" method="post">
<div id="upload-demo"></div>
<input type="hidden" id="imagebase64" name="imagebase64">
<input type="submit" name="submit" value="save" class="upload-result">
</form>
if(isset($_POST['submit'])){
$data = $_POST['imagebase64'];
list($type, $data) = explode(';', $data);
list(, $data) = explode(',', $data);
$data = base64_decode($data);
$imageName = time().'.png';
file_put_contents('images/profile/'.$imageName, $data);
// echo $imageName;
}
这是工作文件。这可能对你有帮助。
