PHP文本編輯器

Question

的index.php

 <h1>View text files in a directory</h1> 

     <form action="" method="POST"> 
     Directory name: <input name="folderName4" type="text" required="required"> <br> 
     <input type="submit" value="View Directories Text Files"> 
     </form> 

     <br> 

     <?php 
     if (isset($_POST['folderName4'])){ 
     $foldername = $_POST["folderName4"]; 

     $directory = "upload"."/".$foldername."/";; 

     $files = glob($directory . "*.txt"); 

     foreach($files as $file) 
     { 
     echo "<a href=edit.php>".$file."</a>"; 
     echo "<br>"; 
     } 
     } 
     ?> 

edit.php

<?php 

$url = 'http://127.0.0.1/ccb/edit.php'; 

$file = ; 

if (isset($_POST['text'])) 
{ 
    file_put_contents($file, $_POST['text']); 

    // redirect to the form, avoids refresh warnings from the browser 
    header(sprintf('Location: %s', $url)); 
    printf('<a href="%s">Moved</a>.', htmlspecialchars($url)); 
    exit(); 
} 

$text = file_get_contents($file); 

?> 

<form action="" method="post"> 
<textarea name="text"><?php echo htmlspecialchars($text) ?></textarea> 
<input type="submit"> 
</form> 

好了，所以index.php文件列出的目錄中的鏈接和edit.php編輯文本文件中的所有文本文件。 edit.php中的$ file變量是文本文件的路徑，我將如何使路徑與鏈接中的文本一旦被點擊相同？這個想法是，一旦文本文件鏈接被點擊，它將在編輯器中打開。任何幫助將不勝感激，謝謝。

不確定這是否是您正在嘗試做的......但是我會使用？file = $文件將文件名添加到URL中，該文件將URL中的數據作爲GET實體傳遞如下編輯，從edit.php文件調用。

的index.php

<form action="" method="POST"> 
    Directory name: <input name="folderName4" type="text" required="required"> <br> 
    <input type="submit" value="View Directories Text Files"> 
    </form> 

    <br> 

    <?php 
    if (isset($_POST['folderName4'])){ 
    $foldername = $_POST["folderName4"]; 

    $directory = "upload"."/".$foldername."/";; 

    $files = glob($directory . "*.txt"); 

    foreach($files as $file) 
    { 
    echo "<a href='edit.php?file=".$file."'>".$file."</a>"; // <-- Filename part of URL 
    echo "<br>"; 
    } 
    } 
    ?> 

edit.php

<?php 

$url = 'http://127.0.0.1/ccb/edit.php'; 

$file = $_GET['file']; // <-- Inserted GET here 

if (isset($_POST['text'])) 
{ 
    file_put_contents($file, $_POST['text']); 

    // redirect to the form, avoids refresh warnings from the browser 
    header(sprintf('Location: %s', $url)); 
    printf('<a href="%s">Moved</a>.', htmlspecialchars($url)); 
    exit(); 
} 

$text = file_get_contents($file); 

?> 

<form action="" method="post"> 
<textarea name="text"><?php echo htmlspecialchars($text) ?></textarea> 
<input type="submit"> 
</form>
