如果这是转贴，我很抱歉。但是我看到很多问题都没有找到正确的答案我正在尝试上传多个文件 + 一些信息，但是如果我提交包含 2 张图片的表单，一切正常，当我上传超过 2 或 3 个文件时，脚本运行完美，我得到所有表单元素的未定义索引。

up.php

   /////// Random name generator ////////
function random_name($length) {
$key = '';
$keys = array_merge(range(0, 9), range('a', 'z'));

for ($i = 0; $i < $length; $i++) {
    $key .= $keys[array_rand($keys)];
}

   return $key;
}

 //sql//
  require("sql.php");
 //////////
 //!!! some vars !!!//
 //
     $total = count($_FILES['pimages']['name']);
 //
 $foldername = random_name(15);
  $target_dir = "../images/projects/".$foldername."/";
   $target_file = $target_dir . basename($_FILES["icon"]["name"]);
     $uploadyes = 1;
    $imageType = pathinfo($target_file,PATHINFO_EXTENSION);
   $saveicon = $target_dir . "icon." .$imageType;

    /////submited form vars /////

  $linkedid = $_POST['lid'];

  $date = date("y.m.d H:i:s");
  $name = $_POST['projectname'];
  $loc = $_POST['location'];
  $type = $_POST['type'];
  $des = $_POST['des'];
  $precara = $_POST['cara'];
  $client = $_POST['client'];
  $col = $_POST['cost'];
  $bua = $_POST['builtup'];

  ////////////////cara slice /////////////
  $caraxarray = explode("," , $precara);
  $cara = base64_encode(serialize($caraxarray));









  echo $imageType ;




  ///////////////////////// Start of the upload check ////////////////////
    if(isset($_POST['submit']) && !empty($name)) {
   $conn = mysqli_connect($servername, $username, $password, $dbname);
   // Check connection
  if (!$conn) {
      die("Connection failed: " . mysqli_connect_error());
  } 
 }










     // Check if $uploadyes is set to 0 by an error
    if (!isset($_POST['submit'])) {
       echo "Sorry, your file was not uploaded.";
  // if everything is ok, try to upload file
   } else {
      mkdir($target_dir);



      if (move_uploaded_file($_FILES["icon"]["tmp_name"], $saveicon)) {
             //////////////////////////..........................//////////////////

    $x = $i + 1 ;
    if ($tmpFilePath != ""){
     //Setup our new file path
  $pimgex = $_FILES['pimages']['name'][$i];

  $pimageType = pathinfo($pimgex,PATHINFO_EXTENSION);

  $newFilePath = $target_dir ."img".$x.".".$pimageType;
  array_push($imgext , "$newFilePath");
      //Upload the file into the temp dir
    if(move_uploaded_file($tmpFilePath, $newFilePath)) {

       echo "yeaaaaaah";

     }
   }
 }
   $str = serialize($imgext);
   $sql1 = "INSERT INTO projects (date, name, type, location, icon, imgext, folder, linkedid)

对不起，如果写得不好，我是初学者，在此先感谢您的帮助

最佳答案

问题是有一个大文件(4mb 图片)而 php 无法发布这个大小的图片所以你必须在上传之前调整你的图片大小..非常感谢 Felippe Duarte。
