PHP Random Image
For a current project I had to take an array of images and make one randomly appear at the top of my page. On refresh or a different page, an image would be picked at random and displayed. It had to be something lightweight and I found one that did what I was asking for without any snags.
<?php /* * Name your images 1.jpg, 2.jpg etc. * * Add this line to your page where you want the images to * appear: <?php include "randomimage.php"; ?> */ // Change this to the total number of images in the folder $total = "12"; // Change to the type of files to use eg. .jpg or .gif $file_type = ".jpg"; // Change to the location of the folder containing the images $image_folder = get_template_directory_uri() . "/images/rotate"; // You do not need to edit below this line $start = "1"; $random = mt_rand($start, $total); $image_name = $random . $file_type; echo "<img src="$image_folder/$image_name" alt="$image_name" />"; ?>
A few notes:
To get this to work in a WordPress template you have to concatenate get_template_directory_uri() at the beginning of the file location, unless you want to put the exact URL in (which makes it hard for local testing and then the switch to a server).
This isn’t necessarily the optimal way to do this as you have to name all of your images 1-whatever number you put as your $total, but it is a quick way to get a random image in your WordPress site.
To call this on a page, just use <?php include ‘/path_to_file/rotate.php’; ?>
