BuddyPress有一个函数（bp\\u member\\u profile\\u data），将配置文件数据拉入members循环，如下所示：

<?php
bp_member_profile_data( \'field=Organization\' );
bp_member_profile_data( \'field=Brief Biography\' );  

/***
* If you want to show specific profile fields here you can,
* but it\'ll add an extra query for each member in the loop
* (only one regardless of the number of fields you show):
* bp_member_profile_data( \'field=the field name\' );   */
 ?>

我想知道如何限制传记的篇幅。我已经看过了Bavatosan示例和substr，但就知道在哪里修改它们而言，它们有点超出了我的能力。

$profile_bio = bp_get_member_profile_data( \'field=Brief Biography\' );

if(strlen($profile_bio) > 50))
  $profile_bio = substr($profile_bio, 0, 50).\'...\';

echo $profile_bio;

ob_start();
bp_member_profile_data( \'field=Brief Biography\' );  
$profile_bio = ob_get_clean();

// rest of the code is the same
