I want to use a solution by @toscho to display and rotate some quotes. The unchanged code works very well, but if I replace the

protected function get_rand()
{
    return rand( 1, 1000 );
}

with (from here)

protected function get_rand()
{
    $array = file("wp-content/plugins/quotes-rotator/quotes.txt");
    $r = rand(0,count($array)-1);
    return $array[rand(0,count($array)-1)];
}

the code works well only at the first page load, but when I press the 'New' button to display a new quote the system outputs an error:

Warning: file(wp-content/plugins/quotes-rotator/quotes.txt): failed to open stream: No such file or directory in /var/www/.../public_html/wp-content/plugins/quotes-rotator/ajax-shortcode-demo.php on line 106

What is wrong here?

  • on the first page load, is the quote read throught the AJAX code or just with PHP ?

  • I think I found the answer in the other question : you use a file ajax-shortcode-demo.php for the AJAX call. I will write a answer to try to correct quickly your problem but I advice you to take time to avoid the use of this file and instead use the AJAX hook of WordPress

to have the good path to the file, try this :

$array = file(plugin_dir_path(__FILE__) . "quotes.txt");

  • Thank you very much! Now is OK! But what you mean by "... instead use the AJAX hook of WordPress"?
