I have searched high and low to find an answer, but can't seem to find one anywhere.
<?php
$f_contents = file("x.txt");
$line = $f_contents[rand(0, count($f_contents) - 1)];
echo($line);
?>
Currently I am getting random results on every page load, but need to return the string only once. I am using Wordpress, so I would preferably like a way to do this only when a page is created.
Any ideas?
You can use the PHP built in uniqid() function:
You need to add a piece of meta information to your page when it gets created.
You can do this by creation your own plugin.
Add an option containing the posts ID and only set this option if it doesn't yet exist.
function random_option($id, $file){
if(get_option("rand_option".$id))
return get_option("rand_option".$id);
$f_contents = file($file);
$value = $f_contents[rand(0, count($f_contents) - 1)];
add_option( "rand_option".$id, $value );
return $value;
}
then call it:
echo random_option(get_the_ID(), "file.txt");
