「致命的錯誤：調用一個成員函數get_text（）null」在wordpress

Question

我使用插件wp-members for wordpress，我需要修改登錄表單，並且在我將數組輸入到函數後，我得到這個錯誤「致命錯誤：調用上的空成員函數get_text（）」

這是我的functions.php

add_filter('wpmem_login_form', 'my_login_form_filter'); 

function my_login_form_filter($form, $action = 'login') 
{ 
     /** 
    * The login form is brought in with $form 
    * You can append to it or filter it 
    * 
    * $action specifies the form being constructed. It 
    * can be: login|pwdreset|pwdchange 
    */ 

$form = array(
    array(
     'name' => $wpmem->get_text("login_username"), 
     'type' => 'text', 
     'tag' => 'log', 
     'class' => 'username', 
     'div' => 'div_text', 
    ), 
    array( 
     'name' => $wpmem->get_text("login_password"), 
     'type' => 'password', 
     'tag' => 'pwd', 
     'class' => 'password', 
     'div' => 'div_text', 
    ), 
    array(
     'name' => $wpmem->get_text("login_number"), 
     'type' => 'text', 
     'tag' => 'log', 
     'class' => 'username', 
     'div' => 'div_text',) 
); 

return $form; 
} 

碼這是插件的代碼有問題

Answer 1

似乎喜歡e您正嘗試在對象$wpmem上調用功能get_text()，但它是null。

您可以嘗試在你的my_login_form_filter函數定義的頂部添加global $wpmem;這樣的：

<?php 
add_filter('wpmem_login_form', 'my_login_form_filter'); 

function my_login_form_filter($form, $action = 'login') 
{ 
global $wpmem; // add this 

Answer 2

$wpmem爲空在你的功能。將global $wpmem添加到您的函數中以使用全局值。
