Flat File .txt + PHP Database Tutorial - Allow user or client to change data - CMS
Listening Video
In this lesson series Adam Khoury demonstrates using .txt Flat File Database systems as an alternative to MySQL, XML, or other database systems. In part 2 you will learn how to allow a user or client to change the data from smart easy web forms. Many people do not have tech knowledge and do not like going on the server to alter a CMS file. You must make forms to alter the data if you wish to have happier higher paying clients.
Lesson Code
<?php
$myfile = "file1.txt";
if (isset($_POST['ta'])) {
$newData = nl2br(htmlspecialchars($_POST['ta']));
$handle = fopen($myfile, "w");
fwrite($handle, $newData);
fclose($handle);
}// ------------------------------------------------if (file_exists($myfile)) {
$myData = file_get_contents($myfile);
}?>Hello user, use this form to edit the writing on your live website
<form action="file.php" method="post">
<textarea name="ta" cols="64" rows="10">
<?php echo str_replace("<br />","",$myData); ?></textarea>
