I am working on a project where the requirement is to download a textarea content as a .txt file on a wordpress site.
After searching previous questions, I got below code which marked as a correct answer.
<html>
<body>
<form action="#" method="post">
<textarea name="text" rows="20" cols="100"></textarea>
<input type="submit" value="submit">Download Text</input>
</form>
<?PHP
if(isset($_POST['submit']))
{
$text = $_POST['text'];
print ($text);
$filename = 'test.txt';
$string = $text;
$fp = fopen($filename, "w");
fwrite($fp, $string);
fclose($fp);
header('Content-disposition: attachment; filename=test.txt');
header('Content-type: application/txt');
readfile('test.txt');
}
?>
</body>
</html>
But for me it is not creating a .txt file. please help me to identify the issue
Your code actually creates a file on the server and it does not get deleted afterwards. If the code failed, it is possible that you didn't have permission to write on your server. You can trim your code down to the following so as no file is generated in the process:
<?php
if(isset($_POST['text']))
{
header('Content-disposition: attachment; filename=test.txt');
header('Content-type: application/txt');
echo $_POST['text'];
exit; //stop writing
}
?>
<html>
<body>
<form action="" method="post">
<textarea name="text" rows="20" cols="100"></textarea>
<input type="submit" value="submit" name="submit">Download Text</input>
</form>
</body>
</html>
Firstly, you should output the file before printing anything on screen and secondly, you forgot to add name="submit" to your original code. I didn't use it here, but I included for you to get an idea.
functions.php or plugin file:
function feed_text_download(){
if(isset($_POST['text_to_download']))
{
header('Content-disposition: attachment; filename=test.txt');
header('Content-type: application/txt');
echo $_POST['text_to_download'];
exit; //stop writing
}
}
add_action('after_setup_theme', 'feed_text_download');
Add the form to one of your template files or in the HTML editor of your post:
<form action="" method="post">
<textarea name="text_to_download" rows="20" cols="100"></textarea>
<input type="submit" value="submit" name="submit">Download Text</input>
</form>
It should be good :)
HTML:
<form action="" method="post">
<label>Filename:<input type="text" name="filename" /></label>
<label>Text:<textarea cols="100" name="text_to_download" rows="20"></textarea></label>
<input type="submit" name="submit" value="Download Text" />
</form>
PHP:
function feed_text_download() {
if ( isset( $_POST['text_to_download'] ) && isset( $_POST['filename'] ) ) {
$filename = sanitize_file_name( $_POST['filename'] );
header( 'Content-disposition: attachment; filename=' . $filename );
header( 'Content-type: application/txt' );
echo $_POST['text_to_download'];
exit; //stop writing
}
}
add_action( 'after_setup_theme', 'feed_text_download' );
