首先,我对 PHP 和编码很陌生,但这里有。

我有一个网络表单,它必须从 txt 文件(位于服务器上的文件夹中)获取一些信息 我知道如何让它从文件中获取信息以及如何制作下拉列表,显示所有文件文件夹。我不知道如何使它们一起工作,因此它读取的文件名取自下拉列表的选定值。

下拉列表的代码:

<? 
$currentdir = 'files'; //change to your directory 
$dir = opendir($currentdir); 

echo 'Files are as follows:<br>'; 
echo '<select name="select">'; 
while($file = readdir($dir)) 
{ 
    echo '<option value="'.$file.'">'.$file.'</option>'; 
} 
echo '</select>'; 
closedir($dir); ?>

以及从文件中读取的代码:

<input type="text" value="<?php $myFile = ""; $lines = file($myFile); echo $lines[2]; ?>" name="refnr" id="refnr" class="input" />

假设下拉显示 2 个文件 test.txt 和 test2.txt,如果我从下拉列表中选择 test2.txt,我希望它把“test2.txt”放在“”之间<?php $myFile = "";但无论我如何尝试将代码放在那里以获取所选值,它都会失败......

我的表单的完整代码现在是:

<?php
if (!empty($_POST)) {

    // Used for later to determine result
    $success = $error = false;

    // Object syntax looks better and is easier to use than arrays to me
    $post = new stdClass;

    // Usually there would be much more validation and filtering, but this
    // will work for now.
    foreach ($_POST as $key => $val)
        $post->$key = trim(strip_tags($_POST[$key]));

    // Check for blank fields
    if (empty($post->refnr))
        $error = true;

    else {

        // Get this directory, to include other files from
        $dir = dirname(__FILE__);

        // Get the contents of the pdf into a variable for later
        ob_start();
        require_once($dir.'/pdf.php');
        $pdf_html = ob_get_contents();
        ob_end_clean();

        // Load the dompdf files
        require_once($dir.'/dompdf/dompdf_config.inc.php');

        $dompdf = new DOMPDF(); // Create new instance of dompdf
        $dompdf->load_html($pdf_html); // Load the html
        $dompdf->render(); // Parse the html, convert to PDF
        $pdf_content = $dompdf->output(); // Put contents of pdf into variable for later

        // Get the contents of the HTML email into a variable for later
        ob_start();
        require_once($dir.'/html.php');
        $html_message = ob_get_contents();
        ob_end_clean();

        // Load the SwiftMailer files
        require_once($dir.'/swift/swift_required.php');

        $mailer = new Swift_Mailer(new Swift_MailTransport()); // Create new instance of SwiftMailer

        $message = Swift_Message::newInstance()
                       ->setSubject('Felanmalan') // Message subject
                       ->setTo(array('mymail@hidden' => 'Fel')) // Array of people to send to
                       ->setFrom(array('mymail@hidden' => 'Fel')) // From:
                       ->setBody($html_message, 'text/html') // Attach that HTML message from earlier
                       ->attach(Swift_Attachment::newInstance($pdf_content, 'Felanmalan.pdf', 'application/pdf')); // Attach the generated PDF from earlier

        // Send the email, and show user message
        if ($mailer->send($message))
            $success = true;
        else
            $error = true;

    }

}
?>

希望这是有道理的,再次抱歉,如果这是一个菜鸟问题:) 我已经使用了 2 天的谷歌搜索和测试,我只是到了需要再次朝着正确方向推动的地步。

提前致谢。

ps 简单解释一下我的目标是什么,然后我有 1 个生成 txt 文件并将其保存在服务器上的网络表单,然后是另一个表单,“管理员”可以从下拉列表中选择文件,获取其中的信息客户填写txt版本,然后填写他需要填写的内容,然后将其保存并以PDF格式发送给技术人员。

你可以使用

echo '<select id="select" name="select">'; 
while($file = readdir($dir)) 
{ 
    echo '<option value="'.$file.'">'.$file.'</option>'; 
} 
echo '</select>'; 

在它被加载到 DOM 之后,使用

document.getElementById('select').onchange=changeSelect;
function changeSelect(){
    document.getElementById('refnr').value=document.getElementById('select').value;
}
changeSelect();

在这里看到它:http: //jsfiddle.net/7nzBS/

谢谢你,Oriol,那行得通:)

代码现在看起来像这样,并且正在按我的需要工作。也感谢所有其他建议,可爱的快速和有用的回复:)

            <label for="refnr"><b>Referensnummer:</b></label>
        <input type="text" value="<?php $selectedfile = @$_POST['file2']; $myFile = "files/$selectedfile"; $lines = file($myFile); echo $lines[0]; ?>" name="refnr" id="refnr" class="input" />

I wanted it to put "test2.txt" in between the "" at `<?php $myFile = ""`

你不能做这样的事情,因为"text2.txt"是在客户端,而$myfile, php 变量是在服务器端。如果要从服务器端访问客户端的数据,则需要通过 HTTP 发送数据。所以你有两个选择:

  1. 通过 HTTP postget发送选定的值。
  2. 通过AJAX发送选定的值。
