如何在我的插件中改变 bp-custom.php

how to variable in bp-custom.php in my plugin

这是bd中的代码-custom.php

global $bp_profile_field_data;
function show_profile_field()
{
    $args = array(
        'field'     => 'Field Name',
        'user_id'   => 1
    );

    $tx_profile_field = bp_profile_field_data( $args );
 };

但我想在插件中使用这个字符串,但它回显为空 space

你从数据库中获取字符串 $matric = $wpdb->get_row("SELECT value FROM wp_bp_xprofile_data WHERE field_id = 2 AND user_id = 3"); // this variable holds the string $matric->value
