Question

我遇到一个问题，PHP页面只返回一行而不是一对。它应该在表中很好地返回多行，但它不会... 如果我删除出现的行，它将显示下一行（但仍然是一行）。

更新：对不起，我没有解释问题是哪个MySQL查询。它是关于“SELECT * FROM users WHERE active = 2 ...”

PS：我知道我应该不使用MySQL而不是PDO或MySQLi，但我很快就会改变它。

     <? $result = mysql_query("SELECT * FROM school WHERE schoolid = '$schoolvanleerling'"); while($row = mysql_fetch_array($result)){
    echo $schoolnaam = $row['schoolnaam'];

     } ?>.

更新的工作代码： 更改是我不再使用$ result多次

echo $schoolnaam = $rowschool['schoolnaam'];
 } ?>.

您只需从您的代码中替换此代码我认为其工作

   <? $resultschool = mysql_query("SELECT * FROM school WHERE schoolid = '$schoolvanleerling'");

   while($rowschool = mysql_fetch_array($resultschool))
   {
     $schoolnaam = $rowschool['schoolnaam'];
     } ?>
