在插件wordpress buddypress中添加过滤器后，为什么不能在主题中使用bp_core_fetch_avatar（）？

Question

After I do the add_filter code below in the first plugin, I cannot use bp_core_fetch_avatar() in the second plugin or in the theme, it echo out the same avatar for every user, why? How can I fix this? get_avatar can echo out different avatar base on the user except that it cannot recognize the $gender that I create in the plugin which will tell if it is a female or male, so avatar will assign base on gender . I am trying to pass some parameter like $gender that I created in the plugin, so that is why I think I should figure out to use bp_core_fetch_avatar(), by the way, does get_avatar can pass a parameter from a plugin?, I know get_avatar( $id, $size,$default, $alt). Anyway, I want to know why bp_core_fetch_avatar() echo out same avatar for every user after do the add_filter, I already add 'item_id'=>"$id". Thanks

  <?php add_filter('bp_core_fetch_avatar',array($this,'set_buddypress_avatar'), 10, 1); ?> 

 <?php public function set_buddypress_avatar($html_data = ''){ $html_doc = new DOMDocument(); $html_doc->loadHTML($html_data); $image = $html_doc->getElementsByTagName('img'); foreach($image as $data) { $original_image = $data->getAttribute('src'); $size = $data->getAttribute('width'); $alt = $data->getAttribute('alt'); if (stripos($alt, 'Profile picture of ') === 0){ // if our alt attribute has "profile picture of" in the beginning... $name = str_replace('Profile picture of ', '', $alt); } else if (stripos($alt, 'Profile photo of ') === 0){ // or profile photo of... $name = str_replace('Profile photo of ', '', $alt); } else { // if there is some problem - just assign alt to name $name = $alt; } } ?>

Because you added a filter to a core BP function. Try removing the filter after you are finished with it in your class.
