使用php在dropdownlist中的两个不同表中显示值

我有两个数据库表,release_movies和coming_movies.我需要在expert_movies表中显示字段rel_movies,在单个下拉列表中的forth_movies表中显示up_movies字段.以下是我的代码.

<select name="film" class="form-control">
<?PHP
include "connection.PHP";
$sql="select rel_movies from released_movies";
$sqlr=$con->query($sql);
while($row=$sqlr->fetch_assoc())
{
?>
<option value="<?PHP echo $row['rel_movies'];?>"><?PHP echo $row['rel_movies'];?></option>
<?PHP
}
?>
</select>

我不知道如何在其中显示up_movies字段.这是可能的.谢谢.

解决方法:

试试这个

    <?PHP include "connection.PHP"; ?>
    <select name="film" class="form-control">
    <?PHP
        $sqlr="select rel_movies from released_movies";
        $sqlrr=$con->query($sqlr);
        while($row=$sqlrr->fetch_assoc()) { ?>
    <option value="<?PHP echo $row['rel_movies'];?>">
<?PHP echo $row['rel_movies'];?>
</option>
    <?PHP }
        $sqlu="select up_movies from upcoming_movies";
        $sqluu=$con->query($sqlu);
        while($rowu=$sqluu->fetch_assoc()){ ?>
    <option value="<?PHP echo $rowu['up_movies'];?>">
<?PHP echo $rowu['up_movies'];?>
</option>
    <?PHP } ?>
    </select>
