PHP在Where子句是我場的空

Question

echo "row->name = '$row->name'"; //prints name correctly 

找不到名稱

$next_row = db_query("select * from field_data_field_department d join taxonomy_term_data t on d.field_department_tid = t.tid where d.entity_id = $entityID and t.name = '$row->name'"); 

返回列變量的字符串：在where子句'

如果1054未知列「我場的名稱」我在MariaDB中運行查詢它的工作原理

select * from field_data_field_department d join taxonomy_term_data t on d.field_department_tid = t.tid where d.entity_id = 10568 and t.name = 'Name of my field';

可能與您訪問對象的事實有關

（請務必爲了規避SQL注入），並嘗試使用CONCAT

$next_row = db_query("select * 
      from field_data_field_department d 
      join taxonomy_term_data t on d.field_department_tid = t.tid 
      where d.entity_id = $entityID and t.name = '" . $row->name ."'");
