PHP passing varibles to external search form then display search result
<p>I have a real estate property listing page containing the property address. I would like to show visitors the property's tax record from the county tax collector's public site.</p>

<p>The tax collector's site has 3 pages. First page has a search form where I would like to pass the property address from my site to the form. Then after clicking "submit", the second page displays the property's account number along with a "detail" button. Click on the "detail" button will take me to the third page where the tax record shows.</p>

<p>The 3rd page has the url "http://taxcollector.com/search_detail.asp?TaxYear=2012&amp;Account=1234567".</p>

<p>Since all I have is the address, I wouldn't know what the account number is when I do the coding. How do I pass the address to the "external" search form, and then display the 3rd page?</p>

<p>I am not looking for someone to do the work for me, but I would appreciate if someone could point me in the right direction. I was reading PHP-get, but I don't think it would do the job. </p>

<p>Update:</p>

<p>I don't plan to redirect the user to the 2nd page where he has to click on the detail button. I would like to have a "see tax record" button on my site, where the user can click to see the 3rd page, skipping the 2nd page. Sorry I should make this more clear.</p>
