在Prestashop，当我删除一些产品时，图像保留在他们的目录/ img / p / so，此时我的图像目录接近2GB。 找到这个脚本来删除Prestashop上无用的和BBDD未链接的图像，但我不知道为什么它只检测孤立图像但不删除它们。也许在php配置上禁用unlink功能？可能吗？或者代码错了？还有另一种方法可以进行这种清理吗？
<?php
// root path of the shop
$shop_root='/home/myweb/public_html/';
// limit number of image files to check, set to 10 for testing
$limit=1000000000;
include $shop_root . '/config/settings.inc.php';
$pdo = new PDO( 'mysql:host='._DB_SERVER_.';dbname='._DB_NAME_, _DB_USER_, _DB_PASSWD_ );
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$r=$pdo->query('select count(1) cnt from ps_image')->fetch();
echo 'count images database: '.$r['cnt'] . "<Br />";
// reset some counters
$cnt_files=0;
$cnt_checked=0;
$cnt_not_found=0;
$cnt_found=0;
for($ii=1; ($ii<=9) && ($cnt_files != $limit); $ii++)
{
$path=$shop_root.'img/p/'.$ii;
delImage($path);
for($jj=0; ($jj<=9) && ($cnt_files != $limit); $jj++)
{
$path=$shop_root.'img/p/'.$ii.'/'.$jj;
delImage($path);
for($kk=0; ($kk<=9) && ($cnt_files != $limit); $kk++)
{

delImage($path);
for($ll=0; ($ll<=9) && ($cnt_files != $limit); $ll++)
{
$path=$shop_root.'img/p/'.$ii.'/'.$jj.'/'.$kk.'/'.$ll;
delImage($path);
}
}
}
}
echo 'files: '.$cnt_files.' checked: '.$cnt_checked.' not_found: '.$cnt_not_found.' found: '.$cnt_found;
function delImage($imageDir)
{
global $limit, $pdo, $cnt_files, $cnt_checked, $cnt_not_found, $cnt_found;
if ($handle = @opendir($imageDir)) { //@ is wriiten to avoid warning message and is handled in else condition
echo $imageDir."<BR />";
while ($cnt_files != $limit && false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
$cnt_files++;
$pi = explode('-',$entry);
if($pi[0]>0 && !empty($pi[1])) {
$cnt_checked++;
if(!checkExistsDb($pdo,$pi[0])) {
$cnt_not_found++;
echo 'rm '.$imageDir.'/'.$entry."<BR />";
unlink($imageDir.'/'.$entry);
} else {
$cnt_found++;
}
}
}
}
closedir($handle);
}
else
{
echo $imageDir." doesn't exist".'<BR />';
}
}
function checkExistsDb($pdo, $id_image) {
$r=$pdo->query($q='select \'ok\' ok, (select id_image from ps_image where id_image = '.(int)$id_image.') id_image');
$row=$r->fetch();
if($row['ok']!='ok') die( 'Problem with query, please correct');
return $row['id_image']?true:false;
}
?>
这是一个输出部分：

检查文件权限。如果php用户没有权限删除其他用户的文件，则unlink功能将无效。

它永远不会有效，因为您删除了路径的根目录： 你删除：/ home / myweb / public_html / img / p / 9/9/7 并且在你想要删除之后：/ home / myweb / public_html / img / p / 9/9/7/0但是/ home / myweb / public_html / img / p / 9/9/7不存在：）
要做到这一点：
for($ii=1; ($ii<=9) && ($cnt_files != $limit); $ii++)
{
$pathRacine=$shop_root.'img/p/'.$ii;
//delImage($path);
for($jj=0; ($jj<=9) && ($cnt_files != $limit); $jj++)
{
$path1=$shop_root.'img/p/'.$ii.'/'.$jj;
//delImage($path);
for($kk=0; ($kk<=9) && ($cnt_files != $limit); $kk++)
{
$path2=$shop_root.'img/p/'.$ii.'/'.$jj.'/'.$kk;
//delImage($path);
for($ll=0; ($ll<=9) && ($cnt_files != $limit); $ll++)
{
$path3=$shop_root.'img/p/'.$ii.'/'.$jj.'/'.$kk.'/'.$ll;
delImage($path3);
}
delImage($path2);
}
delImage($path1);
}
delImage($pathRacine);
}
不要在任何地方使用相同的变量名称

有关您的信息，当您删除产品时，Prestashop会自动删除与该产品相关的所有图像。
我还检查了你的脚本，通过更改$shop_root并添加配置文件，它对我来说很好。
require(dirname(__FILE__).'/config/config.inc.php'); // root path of the shop $shop_root = $_SERVER['DOCUMENT_ROOT']."/";
您需要检查文件夹权限并检查其不允许取消图片链接的原因。

尝试一下。在经历了不同解决方案的多次失败之后，我花了很多时间来开发此工具。对我来说，这是最安全的方法。
<?php
####PUT THIS FILE INTO YOUR MAIN SHOP FOLDER####
// root path of the shop, almost no one needs to change something here.
$shop_root = $_SERVER['DOCUMENT_ROOT']."/"; // need to have slash / at the end
$image_folder = 'img/p/'; // also needs slash at the ennd
$scan_dir = $shop_root.$image_folder;
include_once($shop_root.'config/config.inc.php');
include $shop_root . 'config/settings.inc.php';
