Question

我想获取文本框的值，然后将其传输到文件“prova.txt”

以下是我的PHP代码：

<html>
<head>
    <title>
        write
    </title>
</head>
<body>
<form action="prova.txt" method="POST"> 
<?php
echo" <input type=\"text\" name=\"name\">";
$A=['name'];
$riga = "";
$array = array();
$array=$A;
foreach ($array as $value) {
$riga .= $value . "|";
}

    $fp= fopen('prova.txt', 'a');
    fwrite($fp, $riga);
    fclose($fp);
?>
<input type="submit" value="scrivi sul file">
</form>
</body>

Answer 1

如果您希望PHP处理表单，则必须调用PHP文件（而不是您要写入的文本文件，稍后会出现）。在PHP文件中，POST和GET逻辑必须分开; GET请求将显示表单，POST请求将调用处理程序并写入您的文本文件。

<html><!-- Common header for GET and POST responses-->
<head>
    <title>Write a File</title>
</head>
<body>
<?php // enter PHP Parsing mode

if (!$_POST) {   //no POST has occurred, show the form

?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST"> 
<input type="text" name="name">
<input type="submit" value="scrivi sul file">
</form>

<?php
} else { // a form *has* been POSTed
?
   // sanitize the var $_POST['name'] with a basic filter
   $A  = filter_input(INPUT_POST,'name',FILTER_SANITIZE_STRING);

   // append the sanitized input to our text file
   $fp = file_put_contents('prova.txt', $A, FILE_APPEND);

   // give feedback to the user
   if ($fp) {
       echo "File written successfully";
   } else {
       echo "Problem writing file.";
   }
}
//escape from PHP mode
?>
<!-- this is a common footer for both GET and POST responses -->
</body>
</html>

Answer 2

<html>
<head>
    <title>
        write
    </title>
</head>
<body>
<form action="" method="POST" name="fwrite"> 
<?php
if(isset($_POST['submit'])){
echo" <input type=\"text\" name=\"name\">";
$A=['name'];
$riga = "";
$array = array();
$array=$A;
    $fp= fopen('prova.txt', 'a');
    fwrite($fp, $riga);
    fclose($fp);
}
?>
<input name="submit" type="submit" value="scrivi sul file">
</form>
</body>

试试这个

编辑：您不能将.txt文件用于action，并且应始终为name按钮分配submit。
