You’d be better off using the inbuilt Post Thumbnails, which were introduced in WordPress 2.9 – these are easier to use than custom fields and have things like sizing built in. Once you’ve enabled Post Thumbnails, you can set their default size using set_post_thumbnail_size and then use them in your theme with the_post_thumbnail
I’ve done something similar using gmaps (http://gmap.nurtext.de/). You might want to take a look at that. It’s self explanatory and there’s quite a bit of documentation IF you google around.
You could use regex to only allow alphanumeric characters. $string = preg_replace(“/[^A-Za-z0-9 ]/”, ”, $string);
You can try to make use of filters in query (likely posts_where) to make it look for match between clean value and MySQL REGEXP command (if it fits, didn’t use it myself) with your logic, run on raw value.

For instance: add_filter( ‘the_content’, ‘my_the_content_filter’, 20 ); /** * Add a test to the end of every post page. */ function my_the_content_filter( $content ) { if ( is_singular(‘hotels’) ){ //If a single post is being viewed, add something //Or get the value of a custom field and … Read more
You need the function wp_get_attachment_image_src() see http://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src In your code it would be something like: <?php foreach(get_field(‘connections’) as $relationship): ?> <?php $img = wp_get_attachment_image_src( get_post_meta($relationship->ID, ‘company_logo’, true ), ‘thumbnail’ ); ?> <img src=”https://wordpress.stackexchange.com/questions/40232/<?php echo $img[0]; ?>” width=”<?php echo $image_attributes[1]; ?>” height=”<?php echo $image_attributes[2]; ?>” /> <a href=”<?php echo get_permalink($relationship->ID); ?>”><?php echo get_the_title($relationship->ID) ?></a> <br /> … Read more
