Question

我是一个努力尝试在网站上完成某些功能的菜鸟。不幸的是，我的授权很少，所以我想尽可能简单地创建一个评论框，而不使用数据库或jQuery，JavaScript。

我进行了大量搜索，我认为最简单的方法是创建一个带有注释表单的类似日志的HTML，PHP脚本会在其中附加输入的文本。这是我到目前为止制作的内容：

$file = "updates.html";
$fh = fopen($file, 'a');
$file = "updates.html";
$fh = fopen($file, 'a');
$comment = echo $_POST["update"] \n";
fwrite($fh, $comment);
fclose($fh);

updates.html文件有一个注释框，其中的操作指向包含上述内容的php文件。当然，它不起作用，有一个解析错误，但我不知道如何在那里使用变量（如果这是问题的原因）。我只是想不通怎么做......你有什么建议吗？谢谢！

Answer 1

您打开了两次文件。您不需要回显$ _POST ['update]

<?php 
$file = "updates.html"; 
$fh = fopen($file, 'a'); 
$comment = $_POST["update"] . "\n"; 
fwrite($fh, $comment); 
fclose($fh); 
?>

Answer 2

不知道你想做什么....

 <?php
  if(isset($_POST['update'])) {
     // if a request update exists
     $file = "updates.html";
     file_put_contents($file, $_POST['update']."\n",FILE_APPEND);
  }
  ?>

将其置于文件中可能会导致问题，因为您需要某种分隔符，您可以使用base64对其进行编码并在条目末尾追加\ n

 $input = base64_encode(htmlspecialchars($_POST['update'])); //consider using strip_tags as well to avoid injections

 file_put_contents("updates.html", $input."\n");

获取条目

 $entires = file("updates.html");
 if(count($entries) > 0)
 {
  foreach($entries as $entry)
  {
   echo base64_decode($entry);
  }
 }
 else
 {
   echo 'no entries so far';
 }

如果您不想使用Db，则应考虑至少使用 SimpleXml 。

此答案适用于将来可能会遇到类似问题的任何人。

在没有数据库的情况下添加注释是不切实际的，这是可行的。以下是你如何去做。

步骤1：创建一个文件并使用.php扩展名保存，如comment.php 步骤2.创建通常的html表单并将表单method =“post”并将表单操作设置为文件名，如action =“comment.php”

<h3> Add a comment here </h3>

<form action="comment.php" method="post">
<label for="name">Name:</label>
<input type="text" name="yourname"><br>
<label for="name">Comment:</label> 
<textarea name="comment" id="comment" cols="30" rows="10"></textarea>
<input type="submit" value="submit">
</form>

` 第3步。在同一个文件comment.php中编写一个php脚本来处理表单中的数据。请记住将脚本包含在php标记

中

<?php

$yourname = $_POST['yourname'];
$comment = $_POST['comment'];

// format the comment data into how you want it to be displayed on the page
$data = $yourname . "<br>" . $comment . "<br><br>";

//Open a text file for writing and save it in a variable of your chosen.    
//Remember to use "a" not "w" to indicate write. Using 'w' will overwrite 
// any existing item in the file whenever a new item is written to it.

$myfile = fopen("comment.txt", "a"); 

//write the formatted data into the opened file and close it
fwrite($myfile, $data); 
fclose($myfile);

// Reopen the file for reading, echo the content and close the file
$myfile = fopen("comment.txt", "r");
echo fread($myfile,filesize("comment.txt")); 

?>
