How to Process Indeed.com Job Listing Interface with PHP

PHP Process Indeed.com Job Listing Interface ExampleI’ve worked on a few job recruiting and job listing sites and a few of those sites have requested the ability to show Indeed.com job listings.

The following example is a stand-alone page that will prompt the user for various search criteria then present matching Indeed.com job listing results.

At the bottom, I’ve included some paging in the event the job listing results are more than will fill a page. In order to maintain our search criteria, I’ve included the search criteria in the paging links. This way we can obtain the search criteria from the search form when posted or from the paging links when they are clicked.
