Question

我正在使用它，但似乎不起作用，我做错了什么？谢谢！

<?php if(strlen(strstr($agent,"Firefox")) > 0 ){ ?>
  <object width="692" height="389">
    <param name="allowfullscreen" value="true" />
    <param name="allowscriptaccess" value="always" />
    <param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=VIDEO_ID&amp;server=vimeo.com&amp;color=00adef&amp;fullscreen=1" />
    <embed src="http://vimeo.com/moogaloop.swf?clip_id=<?php the_field('vimeo'); ?>&amp;server=vimeo.com&amp;color=00adef&amp;fullscreen=1"
    type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="692" height="389"></embed>
</object> <?php } else { ?>
    <iframe src="http://player.vimeo.com/video/<?php the_field('vimeo'); ?>" width="692" height="389" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen>   </iframe>
<?php } ?>

它不是过滤，我在Firefox中获取iframe而我不想因为我想要拥有＆lt;对象＆gt;嵌入firefox

Answer 1

strstr区分大小写，请尝试使用stristr而不是不区分大小写并更改＆gt; 0到！== false。

另外，您是否可以提供有关如何填充$ agent的更多详细信息？您应该使用$ _SERVER ['HTTP_USER_AGENT'];

填充$ agent

Answer 2

这似乎有效：

<?php 
  if(strlen(strstr($_SERVER['HTTP_USER_AGENT'],"Firefox")) <= 0 ){ ?>
    <iframe src="http://player.vimeo.com/video/<?php the_field('vimeo'); ?>" width="692" height="389" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>
<?php } else { ?>
    <object width="692" height="389">
<param name="allowfullscreen" value="true" />
<param name="allowscriptaccess" value="always" />
<param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=VIDEO_ID&amp;server=vimeo.com&amp;color=00adef&amp;fullscreen=1" />
<embed src="http://vimeo.com/moogaloop.swf?clip_id=<?php the_field('vimeo'); ?>&amp;server=vimeo.com&amp;color=00adef&amp;fullscreen=1"
    type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="692" height="389"></embed>
    </object> 
<?php } ?>
   <?php else: ?>
   <?php 
         if(strlen(strstr($_SERVER['HTTP_USER_AGENT'],"Firefox")) <= 0 ){ ?>
          <iframe src="http://player.vimeo.com/video/<?php the_field('vimeo'); ?>" width="692" height="389" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>
<?php }

Firefox在php中检测到，代码无效？
