首先,我对PHP和编码很新,但是这里有.
我有一个Web表单,必须从txt文件(位于服务器上的文件夹中)获取一些信息
我得到了如何让它从文件中获取信息以及如何制作下拉列表,显示文件夹中的所有文件.
我怎么想弄清楚如何使它们一起工作,所以它从中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); ?>
<input type="text" value="<?PHP $myFile = ""; $lines = file($myFile); echo $lines[2]; ?>" name="refnr" id="refnr" class="input" />
让我们说下拉列表显示2个文件,test.txt和test2.txt,如果我从下拉列表中选择test2.txt,我希望它将“test2.txt”放在“”at<?PHP $myFile =之间“”;
但无论我如何尝试将代码放在那里以获得所选值,它只是失败…
我现在的表格的完整代码:
<?PHP
if (!empty($_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;
}
}
?>

希望它有意义再次,抱歉,如果它原来是一个菜鸟问题:)我用了2天谷歌搜索和测试,我只是到了一个点,我需要再次向正确的方向推进.
提前致谢.
ps解释我的目标是什么,然后我有1个webform生成一个txt文件并将其保存在服务器上,然后是另一个表单,其中“admin”可以从下拉列表中选择文件,获取信息客户填写了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.
解决方法:
你可以用
echo '<select id="select" name="select">';
while($file = readdir($dir))
{
echo '<option value="'.$file.'">'.$file.'</option>';
}
echo '</select>';
在将其加载到DOM之后,请使用
document.getElementById('select').onchange=changeSelect;
function changeSelect(){
document.getElementById('refnr').value=document.getElementById('select').value;
}
changeSelect();
