}
}
} else {
echo "<p>Error message here</p>";
}

这是我认为问题出在其他代码但我不知道的所有代码
最佳答案
也许你有文件，但没有匹配......
$file_found = false;
if( count($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"/>';
}
