我试图连接$firstname和$lastname作为一个选择框id。我哪里做错了?
echo '<td>
<select name="'$firstname.$lastname'" id="'$firstname.$lastname'">
<option selected disabled>Select Action</option>
<option value="activate">Activate User</option>
<option value="delete">Delete User</option>
<option value="admin">Admin</option>
</select>
</td>';
您需要在名字前后添加连接器:
<select name="'.$firstname.$lastname.'" id="'.$firstname.$lastname.'">
您的连接方式不正确。使用以下语句:
echo '<td>
<select name="'.$firstname.$lastname.'" id="'.$firstname.$lastname.'">
<option selected disabled>Select Action</option>
<option value="activate">Activate User</option>
<option value="delete">Delete User</option>
<option value="admin">Admin</option>
</select>
</td>';
