php - 输出多个记录的PHP

好的，我想我对MySQL表的设置很差。我确定了其他无关紧要的内容，然后是movielink1，movielink2，movielink3，movielink4，movielink5

我希望每个按钮都出现一个按钮，只有在movielink＃存在的情况下。它们中的大多数仅具有movielink1。

我认为我只是以错误的方式看待它。这是我的代码。

             <?php
            $data2 = mysql_query("SELECT movielink1,movielink2,movielink3,movielink4,movielink5 FROM movies WHERE id=$id");
            if (mysql_num_rows($data2) > 0 ) {
            while($info2 = mysql_fetch_array($data2)) {
                Print '<a href="'.$info['movielink1'];.'?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="'.$info['title'];.'"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
                }
            } else {
                Print 'Error!';
            }
            ?>

感谢您的建议，我刚刚添加了它，但是它仍然不能正常工作，也不是解决它的好方法。

        $data1 = mysql_query("SELECT movielink1 FROM movies WHERE id=$id");
        if (mysql_num_rows($data1) > 0 ) {
        while($info1 = mysql_fetch_array($data1)) {
            Print '<a href="'.$info['movielink1'].'?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="'.$info['title'].'"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
            }
        } else {
        }

        $data2 = mysql_query("SELECT movielink2 FROM movies WHERE id=$id");
        if (mysql_num_rows($data2) > 0 ) {
        while($info2 = mysql_fetch_array($data2)) {
            Print '<a href="'.$info['movielink2'].'?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="'.$info['title'].'"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
            }
        } else {
        }
        $data3 = mysql_query("SELECT movielink3 FROM movies WHERE id=$id");
        if (mysql_num_rows($data3) > 0 ) {
        while($info3 = mysql_fetch_array($data3)) {
            Print '<a href="'.$info['movielink3'].'?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="'.$info['title'].'"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
            }
        } else {
        }
        $data4 = mysql_query("SELECT movielink4 FROM movies WHERE id=$id");
        if (mysql_num_rows($data4) > 0 ) {
        while($info4 = mysql_fetch_array($data4)) {
            Print '<a href="'.$info['movielink4'].'?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="'.$info['title'].'"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
            }
        } else {
        }
        $data5 = mysql_query("SELECT movielink5 FROM movies WHERE id=$id");
        if (mysql_num_rows($data5) > 0 ) {
        while($info5 = mysql_fetch_array($data5)) {
            Print '<a href="'.$info['movielink5'].'?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="'.$info['title'].'"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
            }
        } else {
        }

最佳答案

您的代码中有许多小问题。例如，您从结果中获取行并将其设置为$info2，然后调用$info。

这是固定的代码：

$sqlResults = mysql_query("SELECT * FROM movies WHERE id=$id");

if (mysql_num_rows($sqlResults) > 0 ) {
    while($sqlRow = mysql_fetch_array($sqlResults)) {
        if (!empty($sqlRow['movielink1'])) {
            print '<a href="' . $sqlRow['movielink1'] . '?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="' . $sqlRow['title'] . '"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
        }
        if (!empty($sqlRow['movielink2'])) {
            print '<a href="' . $sqlRow['movielink2'] . '?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="' . $sqlRow['title'] . '"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
        }
        if (!empty($sqlRow['movielink3'])) {
            print '<a href="' . $sqlRow['movielink3'] . '?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="' . $sqlRow['title'] . '"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
        }
        if (!empty($sqlRow['movielink4'])) {
            print '<a href="' . $sqlRow['movielink4'] . '?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="' . $sqlRow['title'] . '"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
        }
        if (!empty($sqlRow['movielink5'])) {
            print '<a href="' . $sqlRow['movielink5'] . '?iframe=true&width=100%&height=100%" rel="prettyPhoto[iframes]" title="' . $sqlRow['title'] . '"><img src="http://tipmypicks.com/cssmovie/images/watchmovie.png" class="watchmovie"></a>';
        }

    }
}
else
{
    print 'Error!';
