Question

現在ローカルホスト上で実行されている自分のサイトへのアップロードを送信しています。 .xlsxファイルをアップロードしようとすると、「申し訳ありませんが、このファイルをアップロードできません。申し訳ありませんが、ファイルはアップロードされていません。コードは次のとおりです。

<?php 
$target_dir = "uploads/"; 
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 
$uploadOk = 1; 
$uploadFileType = pathinfo($target_file,PATHINFO_EXTENSION); 


// Check file size 
if ($_FILES["fileToUpload"]["size"] > 500000) { 
    echo "Sorry, your file is too large."; 
    $uploadOk = 0; 
} 
// Allow certain file formats 
if($uploadFileType != "xlsx") { 
    echo "Sorry, you cannot upload this file."; 
    $uploadOk = 0; 
} 
// Check if $uploadOk is set to 0 by an error 
if ($uploadOk == 0) { 
    echo "Sorry, your file was not uploaded."; 
// if everything is ok, try to upload file 
} else { 
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) { 
     echo "The file ". basename($_FILES["fileToUpload"]["name"]). " has been uploaded."; 
    } else {

はこれを試してみてください：

$target_file = $_FILES["myfile"]["name"]; 
$uploadOk = 1; 
$uploadFileType = pathinfo($target_file,PATHINFO_EXTENSION); 


// Check file size 
if ($_FILES["myfile"]["size"] > 500000) { 
    echo "Sorry, your file is too large."; 
    $uploadOk = 0; 
} 
// Allow certain file formats 
if($uploadFileType != "xlsx") { 
    echo "Sorry, you cannot upload this file."; 
    $uploadOk = 0; 
} 
// Check if $uploadOk is set to 0 by an error 
if ($uploadOk == 0) { 
    echo "Sorry, your file was not uploaded."; 
// if everything is ok, try to upload file 
} else { 
    if (move_uploaded_file($_FILES["myfile"]["tmp_name"], $target_file)) { 
     echo "The file ". basename($_FILES["myfile"]["name"]). " has been uploaded."; 
    } else { 
     echo "Sorry, there was an error uploading your file."; 
    } 
}

はあなたの問題を解決しますname="fileToUpload"にご入力ファイルの名前を変更します。

<form action="" method="post" enctype="multipart/form-data"> 
    Select image to upload: 
    <input type="file" name="fileToUpload" id="fileToUpload"> 
    <input type="submit" value="Upload Image" name="submit"> 
</form>
