使用条件语句显示动态内容

Question

我需要基于php的website解决方案。我在主页上有一个证书，其中内容应该从后端动态显示。并且我还需要一个条件语句。如果证书从后台获得批准，则在主页上显示内容，如果没有，则不显示。

的Html炫魅代码

 <aside id="home-marketing-testimonials"> 
      <span class="section_title"><h6 style="color:#fff200; font-weight:bold;">Our Students Say it Best</h6></span> 
      <div class="testimonials" style="text-align:justify;"> 
       <div class="testimonial"> 
       <blockquote style="color:#fff;"> 
        <?php 
      $nsql = mysql_query("select * from testimonials order by id desc limit 0,1"); 
      while($nrow = mysql_fetch_array($nsql)) 
      { 
       ?> 

       <?php echo $nrow[5]; ?></a></strong> 
        <?php 
        $nrowlen = strlen($nrow[1]); 
        if($nrowlen > 220) 
        { 
         echo substr($nrow[1],0,220)."..."; 
        } 
        else 
        { 
         echo "<div style='font-size:12px;color:yellow; margin-top:10px;'>".$nrow[1]."</div>"; 
        } 
        ?> 
       </blockquote> 
        <?php 
      } 
      ?> 
       <strong class="client_identity" style="color:#fff; float:left;"><a class="test_author" href="students-testimonials.php"></a></strong> 
       </div> 


      </div> 

     </aside> 

后端个人鉴定代码：

这与MySQL线前端代码改变时，循环从正确的位置开始，并纠正if/else语句...

<aside id="home-marketing-testimonials"> 
     <span class="section_title"><h6 style="color:#fff200; font-weight:bold;">Our Students Say it Best</h6></span> 
     <div class="testimonials" style="text-align:justify;"> 
     <?php 
      $nsql = mysql_query("select * from testimonials where cstatus=1 order by id desc limit 3"); 
      while($nrow = mysql_fetch_assoc($nsql)) { 
       //start testimonial div and blockquote 
       echo "<div class='testimonial'><blockquote style='color:#fff;'>"; 

       //shorten quote if too long 
       $nrowlen = strlen($nrow['comments']); 
       if ($nrowlen > 220) $nrow['comments']=substr($nrow['comments'],0,220)."..."; 

       //insert quote and end blockquote 
       echo "<div style='font-size:12px;color:yellow; margin-top:10px;'>".$nrow['comments']."</div></blockquote>"; 

       //student identity (start and end) 
       echo "<strong class='client_identity' style='color:#fff; float:left;'><a class='test_author' href='students-testimonials.php'>".$nrow['name']."</a></strong>"; 

       //end testimonial div 
       echo "</div>"; 
      } 
     ?>    
     </div> 
</aside> 

我也用mysql_fetch_assoc，而不是mysql_fetch_array这样我就可以使用的列名（$ nrow [ '名']），而不是列的ID号（$ nrow [1]）

还要注意我在这里使用LIMIT 3。它看起来像在你的网站上，你只需要拉三个引号。如果这可能是一个不同的数字，只需更改数字3.
