我已经得到了可以根据职位数量更改角色的代码。
<?php
add_action( \'save_post\', \'update_roles\' );
function update_roles( $post_id ) {
if ( defined( \'DOING_AUTOSAVE\' ) && DOING_AUTOSAVE )
return $post_id;
// Get the author
$author = wp_get_current_user();
// Set variables for current user information
$count = count_user_posts( $author->ID );
$current_role = (array) get_user_meta( $author->ID, \'wp_capabilities\' );
get_currentuserinfo();
global $user_level;
// Do the checks to see if they have the roles and if not update them.
if ( ($user_level != 10) && ( $count > 3 && $count <= 5 ) && ( array_key_exists( \'contributor\', $current_role[0] ) ) ) {
$user_id_role = new WP_User( $author->ID );
$user_id_role->set_role( \'author\' );
} elseif ( ($user_level != 10) && ( $count > 5 && $count <= 9 ) && ( array_key_exists( \'author\', $current_role[0] ) ) ) {
$user_id_role = new WP_User( $author->ID );
$user_id_role->set_role( \'editor\' );
} elseif ($user_level != 10){
$user_id_role = new WP_User( $author->ID );
$user_id_role->set_role( \'contributor\' );
} return $post_id;
}
?>
现在我已经测试了当地的环境，它是工作，但现在我不知道为什么它给我以下的错误。
Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in /home/....../themes/..../inc/functions/user-role.php on line 20
Warning: Cannot modify header information - headers already sent by (output started at /home/....../themes/..../inc/functions/user-role.php) in /home/...../wp-includes/functions.php on line 861
请帮我解决这个问题。

你必须使用$current_role 变量而不是$current_role[0], 因为电话get_user_meta( $author->ID, \'wp_capabilities\' ); 将返回以角色作为键的数组。
<?php
add_action( \'save_post\', \'update_roles\' );
function update_roles( $post_id ) {
if ( defined( \'DOING_AUTOSAVE\' ) && DOING_AUTOSAVE )
return $post_id;
// Get the author
$author = wp_get_current_user();
// Set variables for current user information
$count = count_user_posts( $author->ID );
$current_role = (array) get_user_meta( $author->ID, \'wp_capabilities\' );
get_currentuserinfo();
global $user_level;
// Do the checks to see if they have the roles and if not update them.
if ( ($user_level != 10) && ( $count > 3 && $count <= 5 ) && ( array_key_exists( \'contributor\', $current_role ) ) ) {
$user_id_role = new WP_User( $author->ID );
$user_id_role->set_role( \'author\' );
} elseif ( ($user_level != 10) && ( $count > 5 && $count <= 9 ) && ( array_key_exists( \'author\', $current_role ) ) ) {
$user_id_role = new WP_User( $author->ID );
$user_id_role->set_role( \'editor\' );
} elseif ($user_level != 10){
$user_id_role = new WP_User( $author->ID );
$user_id_role->set_role( \'contributor\' );
} return $post_id;
}
?>
