开发一个代码,用于从文件夹中选择的文件创建ZIP文件。该文件夹是使用sessiontime作为名称创建的,但文件未添加到ZIP文件中。文件的权限是777.文件被选中,由下面的输出指示。我还通过替换行$ zip-> addFile($ file_folder)来检查代码;它下载了一个空白的zip存档,因此它没有问题。
<?php
ob_start();
$error = ""; //error holder
if(isset($_POST['createpdf']))
{
$post = $_POST;
$file_folder = "test/".$_SESSION["dir_name"]."/"; // folder to load files
echo $file_folder;
if(extension_loaded('zip'))
{ // Checking ZIP extension is available
echo "checking";
if(isset($post['files']) and count($post['files']) > 0)
{ echo "/checking2";// Checking files are selected
$zip = new ZipArchive(); // Load zip library
$zip_name = time().".zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)
{
// Opening zip file to load files
echo "* Sorry ZIP creation failed at this time<br/>";
}
foreach($post['files'] as $file)
{ echo "added";
$zip->addFile($file_folder.$file); // Adding files
into zip
}
$zip->close();
if(file_exists($zip_name))
{
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
我得到的输出是行:test // checking / checking2addedaddedadded
答案 0 :(得分:0)
打开session_start()
代码后忘记了<?php
,因此$_SESSION['dir_name']
变量为空
