Question

我想准备5张照片上传表格，用户需要一次选择所有5张照片并提交表格然后我需要通过将图像重命名为＆＃34; 1.jpg，2.jpg，3.jpg，4.jpg，5.jpg＆＃34;来将所有5张照片存储在目标目录中。我只存储了一个图像，但在添加For循环以保存多个文件后它无法工作....请支持。

//图片上传表格

<form action="saveinntion.php" method="post" enctype="multipart/form-data">

    <h1>Upload Your Innovation</h1
    <fieldset>
        <legend><span class="number">4</span>Upload Images</legend>

        <input type="file" name="img1" id="img1" > 
        </br>
        <input type="file" name="img2" id="img2"> 
        </br>
        <input type="file" name="img3" id="img3"> 
        </br>
        <input type="file" name="img4" id="img4"> 
        </br>
        <input type="file" name="img5" id="img5">
        </br>
    </fieldset>
    <button type="submit">Submit</button>
</form>

saveinntion.php文件

<?php
include("dbconnection.php");
$target_dir = "Upload/";
$img=$_POST['img'];

for ($i = 0; $i < 5; $i++) {
    $target_file = $target_dir . basename($_FILES['$img[]']["name"]);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

    if (file_exists($target_file)) {
        echo "Sorry, file already exists.";
        $uploadOk = 0;
    }

    if ($_FILES['$img[]']["size"] > 500000) {
        echo "Sorry, your file is too large.";
        $uploadOk = 0;
    }

    if($imageFileType != "jpg" && $imageFileType != "jpeg" ) {
        echo "Sorry, only JPG &  JPEG files are allowed.";
        $uploadOk = 0;
    }

    if ($uploadOk == 0) {
        echo "Sorry, your file was not uploaded.";
    } else {
        if (move_uploaded_file($_FILES['$img[]']["tmp_name"], $target_file)) {
            echo "The file ". basename( $_FILES['$img[]']["name"]). " has been uploaded.";
        } else {
            echo "Sorry, there was an error uploading your file.";
        }
    }
}
header("Location: upload1.php?id=$msg");
?>

您的问题与您的命名有关。正如@Twinfriends在命令中所说，它不太可能上传任何文件

在代码中用$ _FILES ['img'。（$ i + 1）]替换 $ _ FILES ['$ img []'] 。

第5行

$target_file = $target_dir . basename($_FILES['img'.($i+1)]["name"]);

第13行

if ($_FILES['img'.($i+1)]["size"] > 500000) {

第25行

if (move_uploaded_file($_FILES['img'.($i+1)]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES['img'.($i+1)]["name"]). " has been   uploaded.";

重命名文件。

$imageFileType = pathinfo($_FILES['img'.($i+1)]["name"],PATHINFO_EXTENSION); 
$target_file = $target_dir . ($i+1).".".$imageFileType;
