Web Service Parameters

vertmonkee

I am using a web service which works fine when I call a method with no parameters but when I try to call a function an dpass parameters to it I get the following error.

Fatal error: Uncaught SoapFault exception: [HTTP] Internal Server Error in C:\Program Files\Apache Group\Apache2\htdocs\index.php:28 Stack trace: #0 [internal function]: SoapClient->__doRequest('<?xml version="...', 'http://grid.bod...', '', 1, 0) #1 [internal function]: SoapClient->__call('searchVocab', Array) #2 C:\Program Files\Apache Group\Apache2\htdocs\medin_metadata\web_services\tutorial.php(28): SoapClient->searchVocab(Array) #3 {main} thrown in C:\Program Files\Apache Group\Apache2\htdocs\medin_metadata\web_services\tutorial.php on line 10

This is my code

<?php

$client = new SoapClient("http://vocab.ndg.nerc.ac.uk/VocabServerAPI.wsdl", array('trace' => 1));

$search_params = array();
$search_params['listKey']		= 'PO21';
$search_params['searchTerm']	= '*emperature*';
$search_params['termType']		= 'short';

$search_vocab = $client->searchVocab($search_params);

echo "<p><pre>" . htmlspecialchars($client->__getLastRequest()) . "</pre></p>";

?>

This is what the web service documentation has to say on the function

Can anyone give me a clue as to where I am going wrong? Thanks for any help

It almost seems like they want strings, not an array. Try using each parameter as a parameter in the soap function:

$client->searchVocab('PO21', '*emperature*', 'short');

If it's not that, then I'd say they're looking for a URL encoded key=value pairing string (like the $_GET string in a regular url):

listKey=PO21&searchTerm=*emperature*&termType=short

Thanks for the reply.

I had tried using the following which should return me a the PO21 list where the short description is like emperature.

However, running the following just returns me all of the lists you can choose form, PO21 being amongst them.

$client->searchVocab('PO21', '*emperature*', 'short');

Using the following

listKey=PO21&searchTerm=*emperature*&termType=short

As a parameter cause the same error as before.

I have emailed the organisation with the problem an am currently awaiting a response.

Thanks for the suggestions.
