Question

我使用PHP将多个文件上传到文件夹。上传完成后，我收到上传的每个文件的浏览器消息。我的问题是如何在完成时为所有人提供消息，如果有错误只显示哪些文件没有上传。这是我的下面的脚本，并提前感谢

<?php

// Count # of uploaded files in array
$total = count($_FILES['filesToUpload']['name']);

// Loop through each file
for ($i = 0; $i < $total; $i++) {
    //Get the temp file path
    $tmpFilePath = $_FILES['filesToUpload']['tmp_name'][$i];

    //Make sure we have a filepath
    if ($tmpFilePath != "") {
        //Setup our new file path
        $newFilePath = "./upimages/" . $_FILES['filesToUpload']['name'][$i];

        //Upload the file into the temp dir
        if (move_uploaded_file($tmpFilePath, $newFilePath)) {
            ?><script>alert('successfully uploaded');</script><?php
        } else {
            ?><script>alert('error while uploading file');</script><?php
        } 
    }
}
?>

只需制作一个简单的变量$error和$succes。您可以在事后（当您的循环结束时）显示那些。我现在已经分别打印了每个错误和成功，你可以用这些数组做任何你想做的事情。

<?php

$total = count($_FILES['filesToUpload']['name']);
$succes = [];
$error = [];
for($i=0; $i<$total; $i++) {
    $tmpFilePath = $_FILES['filesToUpload']['tmp_name'][$i];
    if ($tmpFilePath != ""){
    $newFilePath = "./upimages/" . $_FILES['filesToUpload']['name'][$i];
        if(move_uploaded_file($tmpFilePath, $newFilePath)) {
            $succes[$_FILES['filesToUpload']['name'][$i]] = true;
        }else{
            $errors[$_FILES['filesToUpload']['name'][$i]] = true;
        } 
    }
}
foreach(array_keys($succes) as $suc){
    echo $suc." was succesfull";
}
foreach(array_keys($errors) as $error){
    echo $error." failed to upload";
}

?>

如果您仍希望使用警报执行此操作，可以根据成功或失败将文件名称传递给变量，并在退出for循环后将其包含在警报中。

$successfulmsg="Successfully uploaded: ";
    $failedmsg="error while uploading files: ";
          // Loop through each file
for($i=0; $i<$total; $i++) {
//Get the temp file path
$tmpFilePath = $_FILES['filesToUpload']['tmp_name'][$i];

//Make sure we have a filepath
if ($tmpFilePath != ""){
//Setup our new file path
$newFilePath = "./upimages/" . $_FILES['filesToUpload']['name'][$i];

//Upload the file into the temp dir
if(move_uploaded_file($tmpFilePath, $newFilePath)) {

            $successfulmsg.=$_FILES['filesToUpload']['name'][$i];


    }
    else
    {
        $failedmsg.=$_FILES['filesToUpload']['name'][$i];
    } 
    }       
}

echo '<script>alert("'.$successfulmsg.'. And '.$failedmsg.'")</script>';

回显所有文件已上传的消息
