使用php

Question

我有一个表单，您可以在其中上传图像，然后使用php将其保存到服务器上的文件夹中。 我将输入表单的其他数据存储在xml文件中，也使用php。我现在希望能够将pdf文件/ pdf-data存储在此xml文件中以供以后使用（该表单充当模板，我后来想要将整个信息存储在另一个文件中并将其显示到用户）。 我读到了有关Base64编码等的内容，但我不确定这是否也适用于PDF文件，因为我所能找到的只是如何为图像执行此操作，或者是否有更简单的方法来执行此操作我的情况？

编辑：这是HTML：

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

    <input type="hidden" name="create_xml" value="true">

    <label for="name">Name: </label><br>
    <input type="text" name="name"><br>
    <label for="email">E-mail: </label><br> 
    <input type="text" name="email"><br>
    <label for="textbox">Write something: </label><br>
    <textarea name="textbox" rows="5" cols="40"></textarea><br>
    <label for="fileToUpload">Upload a PDF-file: </label>
    <input type="file" name="fileToUpload" id="file-select">
    <input type="text" name="filename" placeholder="Enter the name of your file"><br>
    <input type="submit" value="submit" name="submit">
</form>

将数据保存到xml文件的php：

if(isset($_POST['create_xml'])) {

    $xml = new DOMDocument();

    $newProfile = $xml->createElement('Profile');
    $xml->appendChild($newProfile);

    $name = $xml->createElement('Name', $name);
    $newProfile->appendChild($name);

    $email = $xml->createElement('EMail', $emailaddress);
    $newProfile->appendChild($email);

    $textbox = $xml->createElement('Text', $text);
    $newProfile->appendChild($textbox);

    $xml->formatOutput = true;
    $xml->saveXML();
    $xml->save($filename.".xml");

}

如果要在DB中插入数据时生成xml：

if($this->input->post('submit')){   
    $name = $_POST['name'];
    $email = $_POST['email'];
    $filename = $_POST['filename'];
    $year = gmdate("Y");

    if($_FILES){
        $_FILES['fileToUpload']['name'] = $files['fileToUpload']['name'];
        $_FILES['fileToUpload']['type'] = $files['fileToUpload']['type'];
        $_FILES['fileToUpload']['tmp_name'] = $files['fileToUpload']['tmp_name'];
        $_FILES['fileToUpload']['error'] = $files['fileToUpload']['error'];
        $_FILES['fileToUpload']['size'] = $files['fileToUpload']['size'];
        $ext = pathinfo($_FILES['fileToUpload']['name'], PATHINFO_EXTENSION);
        $mtime = uniqid(microtime());
        $uniqueid = substr($mtime, 2, 8);
        $pdfname = $uniqueid . '.' . $ext; // pdf file encrypt name here which need to save
        move_uploaded_file($_FILES['fileToUpload']['tmp_name'], 'uploads/' . $pdfname);
    }

    //Your insert query here remember here you should add $pdfname as pdflink 


    // If successful insertion than 
    $xml = new DOMDocument();

    $newProfile = $xml->createElement('Profile');
    $xml->appendChild($newProfile);

    $name = $xml->createElement('Name', $name);
    $newProfile->appendChild($name);

    $email = $xml->createElement('EMail', $email);
    $newProfile->appendChild($email);

    $textbox = $xml->createElement('Text', $filename);
    $newProfile->appendChild($textbox);

    $pdflink = $xml->createElement('Text', $pdfname);
    $newProfile->appendChild($pdflink);

    $xml->formatOutput = true;
    $xml->saveXML();
    $xml->save($filename.".xml");
}
