Question

我的对象的print_r（$ results）返回以下内容：

QueryResult Object 
( [queryLocator] => [done] => 1 [records] => 
Array ( [0] => SObject Object ( [type] => Partner_Research__c [fields] => stdClass Object ( [Partner_Research_URL__c] => http://www.forms.com/184320?tfa_PRID=PR-0167 [Partner_Research_Name__c] => MM Sample Organization-TBR Partner 2011 [Id] => a0V80000003FwjjEAC ) [Id] => a0V80000003FwjjEAC )

[2] => SObject Object ( [type] => Partner_Research__c [fields] => stdClass Object ( [Partner_Research_URL__c] => http://www.forms.com/184320?tfa_PRID=PR-0169 [Partner_Research_Name__c] => Newark Public Schools-TBR Partner 2011 [Id] => a0V80000003FxQ2EAK ) [Id] => a0V80000003FxQ2EAK ) 
[3] => SObject Object ( [type] => Partner_Research__c [fields] => stdClass Object ( [Partner_Research_URL__c] => http://www.forms.com/184320?tfa_PRID=PR-0168 [Partner_Research_Name__c] => Breakthrough Charter Schools-TBR Partner 2011 [Id] => a0V80000003FxPxEAK ) [Id] => a0V80000003FxPxEAK )

[6] => SObject Object ( [type] => Partner_Research__c [fields] => stdClass Object ( [Partner_Research_URL__c] => http://www.forms.com/184320?tfa_PRID=PR-0023 [Partner_Research_Name__c] => Harlem Village Academies-TBR Partner 2011 [Id] => a0V80000003FrEOEA0 ) [Id] => a0V80000003FrEOEA0 ) ) [size] => 7 )

我想使用类似于下面显示的循环来显示一系列结果，但foreach语句不正确。

  foreach ($results as $result)
  {
    $id = $result[fields][Id];
    $name = $result[fields][Partner_Research_Name__c];
    $url = $result[fields][Partner_Research_URL__c];

    $html .= "<tr><td>$id</td><td>$name</td><td>$url</td></tr>";
  }

我需要对foreach语句进行哪些更改才能使我的代码重回正轨？

Answer 1

在这样的问题中帮助我的是尝试在foreach循环中打印。例如，您可以对每个$ result执行var_dump并查看该结构是什么，它可以帮助确定如何继续。

Answer 2

这是我最终如何做到这一点，感谢贡献者提供的帮助。

  foreach ($results->records as $result)
  { 
    $id = $result->fields->Id;
    $name = $result->fields->Partner_Research_Name__c;
    $url = $result->fields->Partner_Research_URL__c;

    $html .= "<tr><td>$id</td><td>$name</td><td>$url</td></tr>";
  }

Answer 3

如果我正确读取您的样本，您的项目是std对象而不是数组。您可能需要像这样引用它们：

  foreach ($results as $result)
  {
    $id = $result->fields->Id;
    $name = $result->fields->Partner_Research_Name__c;
    $url = $result->fields->Partner_Research_URL__c;

    $html .= "<tr><td>$id</td><td>$name</td><td>$url</td></tr>";
  }

上面的print_r示例难以阅读。如果你能提供缩进，那将会有所帮助。

Answer 4

$results是QueryResults对象的名称，我不知道代码中的真实姓名是什么。

foreach ($results->records as $result)
{
  $id = $result->Id;
  $name = $result->fields->Partner_Research_Name__c;
  $url = $result->fields->Partner_Research_URL__c;

  $html .= "<tr><td>$id</td><td>$name</td><td>$url</td></tr>";
}

使用foreach循环访问此queryresult对象中的数组？
