这是在upload.php找到的PHP代码，它处理文件和元数据：
<?php
$r = $_REQUEST;
$p = file_get_contents("../data/photo.json");
$d = json_decode($p, true);
$o = array();
$o['title'] = $r['title'];
$o['desc'] = $r['desc'];
$a = $r['adv'];
$c = explode(" ",$a);
$ext = ".jpg";
$o['ext'] = $ext;
$o['date'] = date("F j, Y"); // For reference only, removed from homepage
$o['user'] = "*******"; // Unused by the system, since the system supports only one user
$o['v'] = 2.0; // The version of the JSON data; used mostly for 'iocus' id check system
$o['adv'] = $a; // For developer ref only, since all advanced options are precompiled and executed as photo uploads
$o['auth'] = "Confedential"; // Ensures legit login
$o['ssl'] = ($_SERVER['HTTPS'] != "" && $_SERVER['HTTPS'] != "off" && $_SERVER['HTTPS'] != NULL); // Verifies HTTPS
$o['ip'] = $_SERVER['REMOTE_ADDR']; // Look at the name
$o['scale'] = $r['scale'];
$id = $d['nxt'];
$o['id'] = $id;
$o['iocus'] = "Confidential"; // Nobody knows what it does, but it's there...
$encoded = json_encode($o);
$d['nxt'] = $d['nxt'] + 1; // The next photo ID
$d['photos'][$id] = $o;
for($i=0;$i<count($c);$i++){
switch($c[$i]){
case "-blank":
$d['photos'][$id] = [];
break;
case "-purge":
echo "Fight the purge! (it isn't functional yet)";
break;
case "":
break;
default:
break;
}
}
$n = json_encode($d,JSON_PRETTY_PRINT);
file_put_contents("../data/photo.json",$n); // Submit JSON
$_FILES['img'];
$thumb = $_FILES['thumb'];
$dir = str_replace("admin","",$_SERVER['DOCUMENT_ROOT']);
$dir .= "photos/";
// Upload photos
if(move_uploaded_file($_FILES['img']['tmp_name'], $dir.$id.$ext)){
echo "Photo: Success<br />";
echo '<div style="color:green;font-size:32pt">GOOD</div>';
}
else{
echo "Photo: Upload Error (Contact your server admin or developer)<br />";
echo '<div style="color:red;font-size:32pt">ERROR</div>';
}
if(move_uploaded_file($thumb['tmp_name'], $dir."thumbnail/".$id.$ext)){
echo "Thumbnail: Success<br />";
echo '<div style="color:green;font-size:32pt">GOOD</div>';
}
else{
echo "Thumbnail: Upload Error (Contact your server admin or developer)<br />";
echo '<div style="color:red;font-size:32pt">ERROR</div>';
}
echo "<br />";
echo "Photo ID (if you lose it, it's easy to find again): ".$id."<br />";
echo 'To leave this page: <a href="/">go back</a>'; // Does not show up on page. Odd...
?>
为了安全起见，一些代码被遗漏了，但我已经证明这些方面不是问题。该页面能够完美地处理较小的文件，它无法上传任何实际大小的内容。发生这种情况时，会保存photo.json上的元数据，而不是实际文件。
答案 0 :(得分：1)
您似乎必须修改upload_max_filesize中post_max_size和php.ini的值，以允许包含更大文件大小的文件：
; Maximum allowed size for uploaded files.
upload_max_filesize = 40M
; Must be greater than or equal to upload_max_filesize
post_max_size = 40M
修改php.ini文件后，需要重启HTTP服务器以使用新配置。
