Can I assign a text string to a number?

[lewisqic]

Hi,

I am looking for someone who can help me out.  I am currently trying to modify my classifieds script, specifically the search form function page.  On my search page, customers are able to input their zip code and then specify the search radius in miles for their search. I currently have options of 10,25,50,100,200,300, and 500 miles. I would like to be able to use an option of "Any Distance" as a drop down menu where it will search within a radius of any distance. I have located the search class script that runs the search engine but I don't know how to manipulate it to make it work as i want it.  I will include the snippet of code from the search class script that I am targeting below...

 

if (strlen(trim($this->zip_filter)) != 0 && $this->zip_filter != 0 && $this->zip_filter != "0")
			{
				$smarty_settings['zip_filter'] = $this->zip_filter;
			}
		}

		$basic_distances = array(10,25,50,75,100,200,300,500);
		$tpl->assign('basic_distances',$basic_distances);
		$smarty_settings['zip_filter_distance'] = $this->zip_filter_distance;

	}

 

Is there any way that I can have the text of "Any Distance" show up for my customers in the drop down menu, and when they select "Any Distance", have it actually search within a radius of 5000 miles or so?  Any help or advice would be greatly appreciated, thank you!

 

Warm Regards,
