如果从查询中返回结果,我将如何重写此代码以仅显示<h3>
标记?
我是PHP的新手,我知道这可以做到,我只是不确定最好的方法。
我能得到的任何帮助都会很棒。
提前谢谢。
我目前的代码如下。
<h3 class="state" name="art">Art</h3>
<?php
if (mysql_error() > "") print mysql_error() . "<br>";
mysql_select_db($database_name, $db);
if (mysql_error() > "") print mysql_error() . "<br>";
$query = mysql_query("SELECT * FROM member_page WHERE community_id = $cityid AND category=1 ORDER BY entity_name");
echo "";
while ($row = mysql_fetch_array($query))
{
echo "<div id='result'><div id='entity_name'><h4>".$row['entity_name']."</h4></div><img width='275' height='170' src='images/".$row['id']."/coverphoto/".$row['cp_path']."' ><div id='searchblurb'><p>".$row['search_blurb']."</p></div><a border='0' href='member-info.php?id=".$row['id']."' onMouseOut='MM_swapImgRestore()' onMouseOver='MM_swapImage('go','','images/custom/go-over.png',1)'><img src='images/custom/go-out.png' alt='Visit this community' width='120' height='40' id='go' border='none'></a>
</div>";
}
echo "";
?>
答案 0 :(得分:1)
您可以尝试这样的事情:
if(mysql_num_rows($query) != 0)
{
echo "<h3 class='state' name='art'>Art</h3>";
}
请注意mysql_* functions
已弃用,请尝试学习 PDO HERE
我不确定这是否是您想要的,但您可以试试这个:
if(mysql_num_rows($query) != 0)
{
echo "<h3 class='state' name='art'>Art</h3>";
while($row = mysql_fetch_array($query))
{
echo "<div id='result'><div id='entity_name'><h4>".$row['entity_name']."</h4></div><img width='275' height='170' src='images/".$row['id']."/coverphoto/".$row['cp_path']."' ><div id='searchblurb'><p>".$row['search_blurb']."</p></div><a border='0' href='member-info.php?id=".$row['id']."' onMouseOut='MM_swapImgRestore()' onMouseOver='MM_swapImage('go','','images/custom/go-over.png',1)'><img src='images/custom/go-out.png' alt='Visit this community' width='120' height='40' id='go' border='none'></a>
</div>";
}
