PHP cURL and SimpleHTMLDom - Can't get ASP Viewstate Value - php

Question

As the title says, how can I get the ASP ViewState Value? I'm using the code below that I thought would work. Thanks!
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://butlercountyclerk.org/bcc-11112005/ForeclosureSearch.aspx");
$data = array(
'Search:btnSearch' => 'Search',
'Search:ddlMonth' => '1',
'Search:ddlYear' => '2011',
'Search:txtCaseNumber' => '',
'Search:txtCompanyName' => '',
'Search:txtLastName' => '',
'__EVENTTARGET' => urlencode('Search:dgSearch:_ctl14:_ctl2'),
'__VIEWSTATE' => 'dDwtMjk2Mjk5NzczO3Q8O2w8aTwxPjs+O2w8dDw7bDxpPDE+Oz47bDx0PDtsPGk8Mz47aTwxOT47PjtsPHQ8dDw7cDxsPGk8MD47aTwxPjtpPDI+O2k8Mz47aTw0PjtpPDU+Oz47bDxwPDIwMDY7MjAwNj47cDwyMDA3OzIwMDc+O3A8MjAwODsyMDA4PjtwPDIwMDk7MjAwOT47cDwyMDEwOzIwMTA+O3A8MjAxMTsyMDExPjs+Pjs+Ozs+O3Q8QDA8Ozs7Ozs7Ozs7Oz47Oz47Pj47Pj47Pj47PmVlaXw5JK161vti9TC+QMdeTNQI'
);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
// Create a DOM object
$html = new simple_html_dom();
// Load HTML from a string
$html->load($output);
// Find all images
$value = $html->find('input[name="__VIEWSTATE"]');
foreach ($value as $v) {
echo $v->value;
}
//echo $value->value;
// close curl resource to free up system resources
curl_close($ch);
//$output;

It would appear as though simple_html_dom is unable to parse some of the HTML. You can "clean" the HTML up through HTML Tidy. Add this before you load $output into simple_html_dom
$tidy = new tidy();
$output = $tidy->repairString($output);
Also you do not need "" around the attribute name.
HTML Tidy is an extension and will need to be loaded by PHP to work.
