How to display a random image in this code?

kokopelli · 10-13-2010, 07:24 PM

Hope one of you PHP gurus can help me ...

In a WordPress theme, I want to change this code:

Code:

<?php if ( function_exists( 'get_the_image' ) ) { get_the_image(array( 'default_size' => 'thumbnail', 'image_scan' => true, 'default_image' => get_bloginfo( 'template_url' ) . '/images/default_thumbnail.png', 'width' => '100', 'image_class' => 'wp-post-image' )); } ?>

to something like
????: NamePros.com http://www.namepros.com/programming/682041-how-to-display-random-image-code.html

Code:

<?php if ( function_exists( 'get_the_image' ) ) { get_the_image(array( 'default_size' => 'thumbnail', 'image_scan' => true, 'default_image' => get_bloginfo( 'template_url' ) . '/images/default_thumbnail_0<?php echo rand(1,3)?>.png', 'width' => '100', 'image_class' => 'wp-post-image' )); } ?>

so a random image between 1 and 3 is displayed as thumbnail.

But my code doesn't work ... no image is displayed

Any idea how I should change it?

The place where you put your rand() function is already inside PHP tags, so instead of opening new ones, you can just concatenate it with the rest of the string like this:

Code:

'default_image' => get_bloginfo( 'template_url' ) . '/images/default_thumbnail_0' . rand(1,3) . '.png',

Thanks, someone already gave me the same solution elsewhere. But much appreciated, anyway.
