在PHP中创建新文件并更新这些创建文件的列表

Question

I am trying to make a website that will hold RPG character sheets dynamically. I would like to be able to create new character sheets by submitting a form with the sheet's title, like this (this is part of the index.php page):

<form action = "charCreate.php" method = "post">
    <h1>Character Sheet Name:</h1> 
    <input type = "text" name = "fileName">
    <input type = "submit" value="Submit">
</form>

I am aware of the fopen method, but I'm not sure exactly how to use it in this scenario. I want to be able to create new webpages with this form, and have the index.php display a list of the files that have been created using the above form.

What would be the best way to dynamically update a list of created webpages and to create these webpages, using the value in the form for the file name.

I also want to find out how to alter these newly created pages, but I need to figure this out first.

Thanks.

Do the following:

<?php
    // w will create a file if not exists
    if($loHandle = @fopen('folder_to_add_files/'.$_POST['fileName'], 'w'))
    {
        echo 'Whoops something went wrong..';
    }
    else
    {
        // you can write some default text into the file
        if(!@fwrite($loHandle, 'Hello World'))
        {
            echo 'Could not right to file';
        }

        @fclose($loHandle);
    }
?>

Watch out for spaces and other weird characters in your filename. You can replace spaces with str_replace like so:

// Replace spaces with underscores
$lstrFilename = str_replace(' ', '_', $_POST['fileName']);

To show the files in the index.php you can do the following:

<?php
    if ($loHandle = @opendir('folder_to_add_files')) 
    {
        echo 'Directory handle: '.$handle.'<br />';
        echo 'Entries:<br />';

        // This is the correct way to loop over the directory.
        while (false !== ($lstrFile = @readdir($loHandle))) 
        {
            echo $lstrFile.'<br />';
        }

        @closedir($loHandle);
     }
?>
