Question

我想告诉你，我的自定义函数使用PHPmailer函数，我用它来发送带有（总是）三个输入的三个附件的电子邮件。

我想问你，有可能升级这种代码的语气更好吗？我是前端，PHP对我来说是一个新的巨大挑战。

PS。我希望这篇文章可以帮助某些人，为了进行自定义，您需要将$filePath变量粘贴到saveFile函数和带有输入的数组中。

在将该文件移动到新的./uploads目录之后，整个函数创建randomHash并将其连接到$_FILES[input-name][name]。将[name]的新补丁保存到全局数组$patch。函数checkData检查文件类型。之后，global $patch为文件提供补丁，以便在sendMail()函数中附加邮件附件。

<?php 
function generateRandomString($length = 10) {
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$charactersLength = strlen($characters);
$randomString = '';
for ($i = 0; $i < $length; $i++) {
    $randomString .= $characters[rand(0, $charactersLength - 1)];
}
return $randomString;
}

function checkData()
{
$typeArray = [ $_FILES['file_one']['type'], $_FILES['file_two']['type'], $_FILES['file_three']['type'] ];

foreach ($typeArray as $key) {
    if ($key != 'image/jpeg' && $key != 'application/msword' && $key != 'image/png' && $key != 'application/pdf' && $key != 'application/zip') 
    {
        echo "File is incorrect!";
        return false;
    }
    else {
        echo "File is correct!";
    }
}
return true;
}

function saveFile()
{
if(checkData() == true)
{
    global $patch;
    $patch = array();
    $multiArray = 
    [
        [$_FILES['file_one']['name'], $_FILES['file_one']['tmp_name']],
        [$_FILES['file_two']['name'], $_FILES['file_two']['tmp_name']],
        [$_FILES['file_three']['name'], $_FILES['file_three']['tmp_name']]
    ];

    foreach ($multiArray as $key) 
    {
        echo "<br />Key: ".$key[0]."\n";
        echo "Key_tmp: ".$key[1]."\n";


        $randomString = generateRandomString();
        $patchFile = './uploads/'.$randomString.$key[0];

        echo "<br />Check patchFile: $patchFile";

        if(is_uploaded_file($key[1]))
        {
            echo "<br />Begin uploading to directory...<br />";
            if(!move_uploaded_file($key[1], $patchFile))
            {
                echo 'Trouble with copy file to uploads directory.';
                return false;  
            }
            else {
                echo "File was saved in uploads directory";
            }   
        }
        else 
        {
            echo "Uploading to directory... FAILED!";
            return false; 
        }

        array_push($patch, $patchFile);
    }
    var_dump($patch);
    return true;
}
else
{
    echo "File format was incorrect.";
    return false;
}

Answer 1

I would use input_filter function instead of $_REQUEST - much safer thing to do. It looks like this: input_filer(INPUT_POST, 'email', FILTER_VALIDATE_EMAIL)

More on the topic you can find here: http://www.sitepoint.com/input-validation-using-filter-functions

In $mail->AltBody you probably want to add some PHP_EOL to break it into lines.

You can also think about using sprintf to achieve more readable code:

sprints('
    <h3>Nakaz Windykacyjny<h3><br />
    Wierzyciel: %s<br />
    Email: %s<br />Dłużnik: %s<br />
    Kwota: %d',

    $borrowman,
    $email,
    $lendman
)

示例= PHPmailer从多个输入[文件]发送带有电子邮件的Form <form>，带有多个附件。升级示例
