Display one or all images from a post's content.
1) How can I customize the Simple Image Grabber function?
The images() function accepts five variables.
The basic use of the function looks like:
<?php images( '1' ); ?> or
<?php images(); ?>
This will display the first image from your post, with its default width and height, no class and a permalink to the post.
This is how the function looks with passing all variables directly or through an array:
<?php images( $number, $width, $height, $class, $permalink, $echo ); ?>
<?php $defaults = array( 'number' => 1, 'width' => null, 'height' => null, 'class' => 'alignleft', 'permalink' => true, 'echo' => true ); images( $defaults ); ?>
$number = the image you want to pull from your post, ie. the first image from the post ('1') or the second image from the post ('2') and so on. NOTE: If you use 'all', it will display all images from the post.
$width = the width of the displayed image
$height = the height of the displayed image
$class = the class you would like to assign to the displayed image
$permalink = whether you would like the image to link to the post or not
$echo = echo or return the value
The following function will echo the second image from a post (if there is one) with a width of 150px and a height of 200px, the class "alignleft" and no link to the post.
<?php images( '2', '150', '200', 'alignleft', false ); ?>
The following will return all images from a post with their original width and height, a class name of alignright and a link to the post.
<?php $args = array( 'number' => 'all', 'class' => 'alignright', 'echo' => 0 ); $all_images = images( $args ); ?>
