使用PHrets从RETS服务器获取空响应

Question

我连接到RETS服务器，我可以使用PHrets库中的函数，如GetMetadataResources，GetMetadataClasses，以及每个类中的所有字段来获取所有元数据，但我无法使用SearchQuery从该服务器获取数据，我尝试了所有方法，但没有运气。

<pre>
    /* Initialize Object */
 require("PHRets_CREA.php");
require("credentials.php");
$rets = new PHRets();
$connect=$rets->Connect($RETSURL, $RETSUsername, $RETSPassword);
    /* Connect */
    /* Query Server */
    if ($connect) {
        echo "Connected";
$resources = $rets->GetMetadataResources();
foreach ($resources as $resource) {
        echo "+ Resource {$resource['ResourceID']}\n";
        $classes = $rets->GetMetadataClasses($resource['ResourceID']);
        foreach ($classes as $class) {
                echo "   + Class {$class['ClassName']} described as " . $class['Description'] . "\n";
        $rets_metadata = $rets->GetMetadata($resource['ResourceID'],$class['ClassName']);
        foreach ($rets_metadata as $field) {
            echo "    + Field: {$field['SystemName']} ({$field['DataType']})\n";
        }
        }
}
/*
$search = $rets->SearchQuery("Property","RE_1","(L_ListingDate=2010-03-02-2010-03-03)");
while ($listing = $rets->FetchRow($search)) {
  echo $listing['L_ListingID'];
        }*/
$search = $rets->SearchQuery("Property","ResidentialProperty","(ListDate=1990-01-01+)",
array( "Count" => 1, "Format" => "COMPACT", "Limit" => "2", "Offset" => "2",
"RestrictedIndicator" => "****", "StandardNames" => 1 )
);
echo "data";
print_r($search);
while ($listing = $rets->FetchRow($search)) 
 echo "{$listing['L_City']}";exit; 
}
$rets->FreeResult($search);
}</pre>

Thanks

Answer 1

首先确保你的资源和类名是正确的。使用http://retsmd.com进行验证。资源通常是"Property“，但是检查你当前拥有的"ResidentialProperty”的类名。它可能是您在上述代码中使用的"RE_1“。

接下来，修改您的SearchQuery。也许可以在选项数组中使用较少的参数，并尝试删除StandardNames并使用默认的系统名称。

如下所示：

$search = $rets->SearchQuery("Property","RE_1","(L_ListingDate=1990-01-01+)", array("Limit" => "10"));

Answer 2

请尝试这个，我们得到了这个的所有活动属性。

$search = $rets->SearchQuery("Property"，"1"，"(135=1990-01-01+)，(246=A)")；
