Adwords API error

Hello I am getting an error when I try to update keyword params and insert the £ into an ad.

Here's my code:

// Get the AdParamService.
$adParamService = $user->GetAdParamService('v200909');

$adgroup_id = $adgroup_id;
$keywordId = $keyword_id;

// Create ad parameters.
$adParam1 = new AdParam($adgroup_id, $keywordId, "$price", 1);

$operation = new AdParamOperation('£$adParam1', 'SET');

$adParams = $adParamService->mutate($operation);

flush();

and here's the output:

Fatal error: Uncaught SoapFault exception: [soap:Server] [RequiredError.REQUIRED @ operations[0].operand.insertionText, RequiredError.REQUIRED @ operations[0].operand.paramIndex, RequiredError.REQUIRED @ operations[0].operand.criterionId, RequiredError.REQUIRED @ operations[0].operand.adGroupId] in /adwords-api/src/Google/Api/Ads/Common/Lib/AdsSoapClient.php:179 Stack trace: #0 /adwords-api/src/Google/Api/Ads/Common/Lib/AdsSoapClient.php(179): SoapClient->__soapCall('mutate', Array, NULL, Array, Array) #1 /adwords-api/src/Google/Api/Ads/AdWords/v200909/cm/AdParamService.php(2152): AdsSoapClient->__soapCall('mutate', Array) #2 /adwords-api/update-prices2/update-keyword-params.php(41): AdParamService->mutate(Object(AdParamOperation)) #3 /adwords-api/update-prices2/set-keyword-params.php(60): include('/web/sites/dusk...') #4 in /adwords-api/src/Google/Api/Ads/Common/Lib/AdsSoapClient.php on line 179

Can't find a solution to this - please help.

Thanks

This is most likely because SOAP uses XML to encode its messages, and £ is not generally a valid character in XML. The entity reference for £ is £ so try using that instead e.g.:

$operation = new AdParamOperation('£$adParam1', 'SET');

£ is sometimes used as an entity reference for £, but this isn't supported in all browsers whereas £ is.

Hi Ian, thanks for the help on this.

I found a way of doing it that's been working:

$AdParam1 = new AdParam($adgroup_id, $keywordId, html_entity_decode('£'.$price_with_delivery _and_voucher, ENT_NOQUOTES, 'UTF-8'), 1);

Basically copied it from a thread I found on Adwords. I'm afraid I've no idea what it means.

Thanks again

Tom

It's basically a different way of doing what I said; '00A3' is 163 converted to hexadecimal, just another way of denoting HTML entities.
