Question

我需要基于php website的解决方案。我在主页页面上有一个推荐，其中的内容应该从后端动态显示。而且我还需要一个条件声明。如果推荐是从后端批准的，那么在主页中显示内容，如果没有，则不显示。

Html主页代码

     <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;">

                  $nrowlen = strlen($nrow[1]);
                  if($nrowlen > 220)
                  {
                        echo substr($nrow[1],0,220)."...";

后端推荐代码：

这是更改mysql行的前端代码，循环从正确的位置开始，if / else语句已更正...

<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>

我还使用了mysql_fetch_assoc而不是mysql_fetch_array，这样我就可以使用列名（$ nrow [＆＃39; name＆＃39;]）而不是列id号（$ nrow [1]）

另请注意我在这里使用LIMIT 3。在您的网站上看起来只有三个引号。如果这可能是不同的数字，只需更改数字3。

使用条件语句显示动态内容
