[Resolved] Nusoap and Google problem

[Norman_Graham]

Dear all

I've just been testing the Google API this afternoon. It's fab. I've been using some of the ready-made Perl scripts from the O'Reilly Google Hacks book. I'm now trying to get the PHP example to work. I've got nusoap.php (taken untouched from http://dietrich.ganx4.com/nusoap/index.php) and I've got the following script (googly.php). I've also loaded up the GoogleSearch.wsdl file to my web account - you'll see it specified in my script.

My problem is: it always returns no results. There are no error messages, so I can't work out what's wrong. As far as I can make out from nusoap.php, I do have debugging turned on, so I don't understand why there are no error messages. Here's googly.php - it takes the 'query' variable from a simple form. Everything works, but I always get the 'no results' message. Any hints as to my error? I suspect it may be something stupid, but I can't see it at the minute.

<?php

/*
|googly.php: Process user queries using Google API|
*/

// Doctype declaration, CSS, title and meta-tags

require_once("nusoap.php");

// A load of explanatory HTML stuff

# Set parameters
$parameters = array(
  "key"=>"mygooglekey",
  "q" => $_GET["query"],
  "start" => 0,
  "maxResults" => 10,
  "filter" => false,
  "restrict" => "",
  "safeSearch" => false,
  "lr" => "",
  "ie" => "utf-8",
  "oe" => "utf-8"
);

// Create a new SOAP client, feeding it GoogleSearch.wsdl
$soapclient = new soapclient("GoogleSearch.wsdl", "wsdl");

// query Google
$results = $soapclient->call("doGoogleSearch",$parameters);

// Results?
if (is_array($results["resultElements"]))
	{
  print "<p>Your Google query for \"" . $_GET["query"] . "\" found "
   . $results["estimatedTotalResultsCount"] . " results, the top ten of which are:</p>";
  foreach ( $results["resultElements"] as $result ) {
    print 
      "<p><a href=\"" . $result["URL"] . "\" target=\"_blank\">" . 
      ( $result["title"] ? $result["title"] : "no title" ) .
      "</a><br />" . $result["URL"] . "<br />" .
      ( $result["snippet"] ? $result["snippet"] : "no snippet" ) .
      "</p>";
  }
}

// No Results
else {
  print "Your Google query for \"" . $_GET["query"] . "\" returned no results";
}

?>

Thanks for any hints you can offer

I've never done this before - but my question is no longer in the recent posts selection, so I'm resorting to underhand methods.

Can anyone help me with nusoap and my Google API script?

Thanks guys and gals

Well, I've managed to answer my own question. I'm adding the code here so that all may benefit. The answer to my problem is that the nusoap class doesn't directly address the .wsdl file. It goes through the URL provided by Google (http://api.google.com/search/beta2). A local copy of GoogleSearch.wsdl doesn't work. Don't ask me where this is specified in nusoap.php - it has over 4000 lines of code and I shall have to look at it in a quieter moment. Anyway, the following example is a primitive but functioning search interface, which should get you started. It combines the two examples from Google Hacks (O'Reilly, pp. 149) and DevShed (article by Harish Kamath: http://www.devshed.com/Server_Side/PHP/GoogleAPI/page1.html). As I say, it's primitive, but it's all you need to get started.

// HTML stuff here

<?php

if (!$_POST['q'])
{
?>

<h2>Search</h2>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
Search term: <input type="text" name="q" />
</form>

<?php
}

else
{
// include the class
include("Includes/nusoap.php");

// create a instance of the SOAP client object
$soapclient = new soapclient ("http://api.google.com/search/beta2");

// uncomment the next line to see debug messages
// $soapclient->debug_flag = 1;

// set up an array of query parameters
$params = array(
'key' => 'myGooglekey',
'q'   => $_POST['q'],
'start' => 0,
'maxResults' => 10,
'filter' => true,
'restrict' => '',
'safeSearch' => false,
'lr' => '',
'ie' => '',
'oe' => ''
);

// invoke the method on the server
$result = $soapclient->call("doGoogleSearch", 
$params, "urn:GoogleSearch", "urn:GoogleSearch"); 

// print the results of the search
if ($result['faultstring'])
{
?>

<h2>Error</h2>

<?php

echo $result['faultstring'];

}

else
{
?>

<h2>Search Results</h2>
Your search for <b>
<?php =$result['searchQuery']?></b> produced 
<?php =$result['estimatedTotalResultsCount']?> hits.
<br />
<ul>

<?php
if (is_array($result['resultElements']))
{
foreach ($result['resultElements'] as $r)
{
echo "<li><a href=" . $r['URL'] . ">" .
$r['title'] . "</a>";
echo "<br />";
echo $r['snippet'] . "(" .
$r['cachedSize'] . ")";
echo "<p>";
}
}
?>
</ul>
<?php
}
}
?>

//end HTML stuff here

Hope that's useful for somebody out there, and happy Googling.
