PHP文本编辑器

Question

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>

好的，index.php将目录中的所有文本文件作为链接列出，edit.php编辑文本文件。$file变量在edit.php中是文本文件的路径，单击链接后如何使路径与链接中的文本相同？这个想法是，一旦点击了文本文件链接，它就会在编辑器中打开。任何帮助都将不胜感激，谢谢。

不太确定这是不是你想做的..。但是我会使用?file=$file将文件名添加到URL中，这将把URL中的数据作为一个GET实体传递，该实体可以按照下面的编辑从edit.php文件中调用。

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>
