上传并插入表后获取文件大小的代码不起作用 [英] Code to get file size after upload and insert into table is not working

问题描述

我有一个MySQL/PHP项目，当前有一个文件表，该表创建虚拟文件夹并链接到上载的文件，上载和访问工作正常，但是我刚刚添加了大小"字段并修改了我的代码以进行更新上传到表格后的文件大小，但是代码不起作用.我没有收到任何错误，文件仍然上传，但是代码在相关字段中插入了空值.代码如下:

I have a MySQL/PHP project that currently has a files table that creates virtual folders and links to uploaded files, the upload and accessing works fine, however i have just added the field 'size' and have amended my code to update the file size after upload into the table, however the code is not working. I get no errors and the file still gets uploaded but the code is inserting a null value into the relevant field. Code is below:

global $dal;
$tblDocs = $dal->Table("doc_files");
$fileArray = my_json_decode($values["file"]);

for($i = 0; $i < count($fileArray); $i++)
{
$tblDocs->Value["parent_folder_id"]=$_SESSION["current_folder"];
$tblDocs->Value["file_type"]="file";
$tblDocs->Value["file"]=my_json_encode(array($fileArray[$i]));
$tblDocs->Value["hash"]=generatePassword(HASH_LENGTH);
$tblDocs->Value["name"]=$fileArray[$i]["usrName"];
$tblDocs->Value["ownerid"]=$_SESSION["user_id"];
$tblDocs->Value["created"]=now();
$tblDocs->Value["filesize"]=formatBytes($fileArray[0]["size"],2);

$tblDocs->Add();

}

推荐答案

您使用了错误的索引:

$tblDocs->Value["name"]=$fileArray[$i]["usrName"];
                                   ^^--here you use the loop index

$tblDocs->Value["filesize"]=formatBytes($fileArray[0]["size"],2);
                                                   ^---hard-coded index
