How to return this XML-RPC response in an array using PHP?
- by mind.blank
I'm trying to put together a WordPress plugin and I want to grab a list of all categories (of other WordPress blogs) via XML-RPC. I have the following code and it looks like it works so far:
function get_categories($rpcurl,$username,$password){
$rpcurl2 = $rpcurl."/xmlrpc.php";
$params = array(0,$username,$password,true);
$request = xmlrpc_encode_request('metaWeblog.getCategories',$params);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $rpcurl2);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
$results = curl_exec($ch);
$res = xmlrpc_decode($results);
curl_close($ch);
return $res;
}
If I use $res I get the following string as the response: Array
If I use $results then I get:
categoryId17 parentId0 descriptionTest categoryDescription categoryNameTest
htmlUrlhttp://test.yoursite.com/?cat=17 rssUrlhttp://test.yoursite.com/?feed=rss2&cat=17
categoryId1 parentId0 descriptionUncategorized categoryDescription
categoryNameUncategorized htmlUrlhttp://test.yoursite.com/?cat=1
rssUrlhttp://test.yoursite.com/?feed=rss2&cat=1
I need to pull out the names after description so Uncategorized and Test in this case.
It's my first time coding in PHP. I got these results by echoing them to the page, so not sure if they get changed in that process or not...
By the way I modified the above code from one that posts to a WordPress blog remotely so maybe I haven't set some of the options correctly?
With var_dump($res) I get:
array(2) { [0]=> array(7) { ["categoryId"]=> string(2) "17" ["parentId"]=> string(1)
"0" ["description"]=> string(4) "Test" ["categoryDescription"]=> string(0) ""
["categoryName"]=> string(4) "Test" ["htmlUrl"]=> string(40)
"http://test.youreventwebsite.com/?cat=17" ["rssUrl"]=> string(54)
"http://test.youreventwebsite.com/?feed=rss2&cat=17" } [1]=> array(7) {
["categoryId"]=> string(1) "1" ["parentId"]=> string(1) "0" ["description"]=>
string(13) "Uncategorized" ["categoryDescription"]=> string(0) "" ["categoryName"]=>
string(13) "Uncategorized" ["htmlUrl"]=> string(39) "http://test.youreventwebsite.com/?cat=1"
["rssUrl"]=> string(53) "http://test.youreventwebsite.com/?feed=rss2&cat=1" } }
