如何使用会话/函数或javascript将变量从插件php传递到wordpress中的另一个php文件？

我有一个插件文件testplugin.php..它包含变量$abc

//main plugin.php

if(!is_admin()){
new Funtion_Button();
}
class Function_Button
{

if(is_single() || is_page() || is_home() ){  
      global $post; 
      global $wpdb; 

 $query_images_args = array(
     'post_type' => 'attachment' , 'post_mime_type' =>'image','post_status' => 'published', 'posts_per_page' => -1,'numberposts' => 1

$query_images = new WP_Query( $query_images_args );
         $images = array();
         foreach ( $query_images->posts as $image) {
         $images[]= wp_get_attachment_url( $image->ID );

         }
                 $abc[]=0;
         $abc= $abc.http_build_query($images);
                 $_SESSION['arrayImg']=$abc;
 );
}

session_start();
$_SESSION['varname'] = $var_value;

$_COOKIE['varname'] = $var_value;

///接收文件

include ('testplugin.php'); 
session_start();
$array1[]=$abc;

现在这个$abc来自主插件页面

但我得到了这个错误

致命错误：对未定义函数的调用是第98行C:\wamp\www\wordpress\wp content\plugins\testplugin.php中的\u admin（）

在98行中，我有

如果（！is_admin（））{

使用会话：

//关于testplugin.php

if(!is_admin()){
new Funtion_Button();
}
class Function_Button
{

if(is_single() || is_page() || is_home() ){  
      global $post; 
      global $wpdb; 

 $query_images_args = array(
     'post_type' => 'attachment' , 'post_mime_type' =>'image','post_status' => 'published', 'posts_per_page' => -1,'numberposts' => 1

$query_images = new WP_Query( $query_images_args );
         $images = array();
         foreach ( $query_images->posts as $image) {
         $images[]= wp_get_attachment_url( $image->ID );

         }
                 $abc[]=0;
         $abc= $abc.http_build_query($images);
                 $_SESSION['arrayImg']=$abc;
 );
}

session_start();
$_SESSION['varname'] = $var_value;

$_COOKIE['varname'] = $var_value;

//在另一个文件上

session_start();
$var_value = $_SESSION['varname'];

使用cookies：

//关于testplugin.php

if(!is_admin()){
new Funtion_Button();
}
class Function_Button
{

if(is_single() || is_page() || is_home() ){  
      global $post; 
      global $wpdb; 

 $query_images_args = array(
     'post_type' => 'attachment' , 'post_mime_type' =>'image','post_status' => 'published', 'posts_per_page' => -1,'numberposts' => 1

$query_images = new WP_Query( $query_images_args );
         $images = array();
         foreach ( $query_images->posts as $image) {
         $images[]= wp_get_attachment_url( $image->ID );

         }
                 $abc[]=0;
         $abc= $abc.http_build_query($images);
                 $_SESSION['arrayImg']=$abc;
 );
}

session_start();
$_SESSION['varname'] = $var_value;

$_COOKIE['varname'] = $var_value;

//第2页

$var_value = $_COOKIE['varname'];

阅读此文，谢谢@pranshu它起作用了。我不需要在第二页包含testplugin.php？？？@user1145009不，你不需要在下一页包含testplugin.php，因为你正在使用cookies和session，cookies和session的值临时存储在浏览器中。因此，不需要包含用于传递此变量的值。我正在尝试ng在localhost中它工作了..但是现在我已经在wordpress主题上使它联机..sesion变量没有存储。。
