也许你有文件,但没有匹配的

$file_found = false;
if( count($files) ) {
    foreach( $files as $f ) {
        if(strpos($f, $search) !== false and strpos($f, '.nav') === false and strpos($f, '.jpg') === false and strpos($f, '.txt') === false and strpos($f, '.jpe') === false or !isset($_GET["search"]) or $search == ""){
            $f1 = str_replace('maps/', '', $f);
            $f1 = str_replace('.bz2', '', $f1);
            $f1 = str_replace('.bsp', '', $f1);
            echo "<div class='ciao'><p>{$f1} <a download href='{$f}'>Download</a></p></div><br>";
            $file_found = true;
        }
    }
}

if(!$file_found){
    echo "<p>Non è stata trovata nessuna mappa con questo nome</p>";
    echo '<img src="yourimagehere.jpg"/>';
}
$file\u found=false;
如果(计算($文件)){
foreach($f文件){
if(strpos($f,$search)!==false和strpos($f,'.nav')==false和strpos($f,'.jpg')==false和strpos($f,'.txt')==false和strpos($f,'.jpe')==false或!isset($\u GET[“search”])或$search==“”){
$f1=str_replace('maps/','','$f);
$f1=str_替换('.bz2','$f1);
$f1=str_替换('.bsp','$f1);
回声“{$f1}


”; $file\u found=true; } } } 如果(!$file\u找到){ echo“Nonèstata trovata nessuna mappa con questo nome

”; 回声'; }
什么不起作用?你得到一个php错误?你应该看到的时候却看不到图像?你得到了下载链接,但期望收到错误消息?检查你的计数。如果(count($files)>0{不,我想在我按send时看到错误消息,如果文件不存在,网站会告诉你:文件不存在或类似的东西我没有类似if(count($files)>0的东西,我需要在那里添加这个。不,抱歉,伙计,它工作了,我无法复制代码,非常感谢
