最近客户要求后台需要能上传word 转html到编辑器中
因为网站是thinkphp5做的 编辑器是使用的百度编辑器 根据网上介绍写了这个功能

![PG4$NGA{G(2E`A491M`T[]1.png](https://attach.52pojie.cn/forum/202010/13/181043so5az6cj61mk5h7x.png "PG4$NGA{G(2E`A491M`T[]1.png")
先在页面合适的位置写个上传框
[HTML] 纯文本查看 复制代码 <button type=”button” name=”fileword” id=”upload-fileword”>上传word文件</button>
我这里是使用layui
[JavaScript] 纯文本查看 复制代码 <script>
layui.use('upload', function () {
var upload = layui.upload;
upload.render({
elem:'#upload-fileword',
accept:'file',
url: '".url('upload/uploadword',['file'=>'file'])."',
exts: 'docx',
done: function(data){
if(data.status == 1){
UE.getEditor('".$field."').setContent(data.html);
layer.msg(data.msg,{icon:1,time:1500,shade: 0.1,});
}else{
layer.msg(data.msg,{icon:2,time:1500,shade: 0.1,});
}
}
});
});
</script>
php上传代码
[PHP] 纯文本查看 复制代码 $upload = new \tool\WordUpload(input('file'));
$html = $upload->getHtml();
if ($html === false) {
return json(['status' => 2, 'html' => $html, 'msg' => '解析失败']);
}else{
return json(['status' => 1, 'html' => $html, 'msg' => '解析成功']);
}
WordUpload文件 需要phpword包 自己下载
