我尝试检索对象的值( stdClass )我想获得实习生的名字 title .

I try to retrieve the value of an object (stdClass) I want to get the internship his name the title.

(["title"]=> string(53) "Mss ( Privaatpraktijk kinesitherapie Walravens Marc )").

我的代码:

foreach($gStartPositionStudents as $value) { foreach($gStartPositionInternships as $value2) { // each loop will add a row here. $row = array(); // build the row $row[] = array('data' => $value->field_ugentid_student[0]['value']); $row[] = array('data' => $value2->title[0]['value']); } // add the row to the "big row data (contains all rows) $rows[] = array('data' => $row); } $output = theme('table', $header, $rows); return $output;

对象数组:

推荐答案

据我所知，实际上您已经为对象中的众多变量分配了一个数组.结果，您将需要在 foreach 循环中执行以下操作:

Well, as far as I can tell, you've actually assigned an array to the numerous variables in the object. As a result, you will need to do something like this in your foreach loop:

global $gStartPositionStudents; global $gStartPositionInternships; $rows = array(); foreach($gStartPositionStudents as $value) { // each loop will add a row here. $row = array(); // build the row $row[] = array('data' => $value->field_naam_student[0]['value']); $row[] = array('data' => $gStartPositionInternships->field_stagedomein_revaki); // add the row to the "big row data (contains all rows) $rows[] = array('data' => $row); } $output = theme('table', $header, $rows); return $output;
