This short code returns the current page’s WPML language code. As always register it first in Views if you want to use it with Toolset. Can be useful to display content depending on current language
/**
*Add ICL_LANGUAGE_CODE shortcode
*/
function wpml_language_code_value_func() {
$return = ICL_LANGUAGE_CODE;
return $return;
}
add_shortcode('wpml_language_code_value', 'wpml_language_code_value_func');
This short code can be used to get the User’s Gravatar determining he’s / her’s email as attribute
/**
* Add Gravatar Support for Views
*/
function otgs_gravatar($atts) {
return get_avatar( $atts['email'] );
}
add_shortcode('otgs-gravatar', 'otgs_gravatar');
Use it like this:
[otgs-gravatar email="user_email@site.com"]
Hides the “default” menu for non logged in users and instead displays a Custom Menu (in this case called “unlogged”)
The menu must of course be set up as a menu in Dashboard > Appearance A Menu, but not be displayed anywhere by default.
/**
*Used to remove menu for non logged users and display custom menu instead
*Do NOT redecalre the menu LOGGED in users see, because, other wise he will see always the SAME menu (like in custom menus, he will see the default menu)
*/
function my_wp_nav_menu_args( $args = '' ) {
if( !is_user_logged_in() ) {
$args['menu'] = 'unlogged';
}
return $args;
}
add_filter( 'wp_nav_menu_args', 'my_wp_nav_menu_args' );
Redirects to the Home URL if the login failed.
/**
*Used to redirect if login failed
*/
function login_failed() {
$login_page = home_url();
wp_redirect( $login_page . '' );
exit;
}
add_action( 'wp_login_failed', 'login_failed' );
Redirects to the Home URL after Logout from the Admin (or elsewhere)
/**
*Used to redirect if logout
*/
function logout_page() {
$login_page = home_url();
wp_redirect( $login_page . "" );
exit;
}
add_action('wp_logout','logout_page');
This snippet allows “Members only” sites.
It redirects always to a custom PHP template (noaccess) if the user is not logged in, and obviously it will NOT redirect anywhere if the User access the custom template (noaccess).
Other wise a infinite loop would be generated.
/**
*Used to redirect if not logged in
*/
function admin_redirect() {
if ( !is_page('noaccess') && ! is_user_logged_in() ) {
wp_redirect( home_url('/noaccess/') );
exit;
}
}
add_action('get_header', 'admin_redirect');
Removes the WP Admin Bar for a given Role (contributor in this case)
function remove_admin_bar_user() {
if( current_user_can('contributor')) {
show_admin_bar(false);
}
}
add_action('after_setup_theme', 'remove_admin_bar_user');
This short CRED Code allows you to get the TODAY’s Date in seconds from Timestamp begin and update a Date Field (Types) with this value. Since Views can currently not handle post_date in Parametric Searches this can be useful to find posts by Publish Date (let’s say you updated the CF with TODAY date on post creation)
/**
*Update news post date to a CF since Views cant handle Post Date in param search
*/
function update_post_date_save_data_action($post_id, $form_data){
// Change your CRED Form "ID" accordingly below
if ($form_data['id']==ID){
// get current date, returns full Timestamp
$post_date = date("U");
//update the CF with current post date
update_post_meta( $post_id, 'wpcf-date_field_slug', $post_date );
}
}
add_action('cred_save_data', 'update_post_date_save_data_action',10,2);
This code allows you to assign a specific Layout to Posts in “draft” mode only. Read inline comments as well, the thread is interesting too.
function assign_layout_by_post_status( $id, $layout ){
global $post;
$preferred_layout = 5745; // my layout ID
$control_layout = 0; //just set to 0 if you don't have any layout set for your post/product
if( $id === $control_layout && $post->post_status === 'draft' && $post->post_type === 'product'){
return $preferred_layout;
}
return $id;
}
add_filter('get_layout_id_for_render', 'assign_layout_by_post_status', 10, 2);
Let a user edit his existing WordPress Profile directly from the FrontEnd through a CPT Edit/Create CRED form.
Note that this function assumes a setup with the correct CPT’s, custom fields, user CF’s.
The Process of this example CRED Form will create a CPT “user Profile” entry , which can be used for front-end displaying user profiles (with a content template as example).
During this, it will get the CPT field values and update the USER fields with it.
This example is also useful to see how checkboxes (multi-options) are different then “normal” CF’s.
function user_save_data_action($post_id, $form_data) {
if ($form_data['id']==ID) {
//get curretn user's ID
$user_id = get_current_user_id();
//get Skype post_meta field value he submits in post
//note: any other SINGLE option Field applies to below "rule")
$skype = get_post_meta( $post_id, 'wpcf-skype', true );
//update the user_meta field with this value
update_user_meta($user_id, 'wpcf-skype', $skype);
//repeats as above
//again, ANY single value Field can be used (email, URL, etc)
$phone = get_post_meta( $post_id, 'wpcf-phone-number', true );
update_user_meta($user_id, 'wpcf-phone', $phone);
$pic = get_post_meta( $post_id, 'wpcf-profile-photo', true );
update_user_meta($user_id, 'wpcf-profile-image', $pic);
//now the tricky part, we are handling with CheckBoxes, multiple Options!
//AGAIN, THANK YOU +Ana Couto !!!!
//Check if actually the post_meta Checkboxes field has value(s)
if ( isset($_POST['wpcf-languages'])){
//if yes, get all the user meta fields and custom fields information (of user + post)
$langs_user = get_option( 'wpcf-usermeta' );//users fields
$langs_fields = get_option( 'wpcf-fields' );//posts fields
//refine this, we only want specific fields, actually the "languages" and "support-languages" fields
//being those the checkboxes fields (with options), once for user, once for post
$langs_user_options = $langs_user['support-languages']['data']['options'];//user field
$langs_fields_options = $langs_fields['languages']['data']['options'];//post field
//check the field's values against each other (user_meta vs post_meta field values)
$langs_selected = $_POST['wpcf-languages'];//get values from post field (all of them)
//define the data with which we are going to update user_meta field
$user_langs = array();
foreach ($langs_selected as $fields_option_key) {
if (isset($langs_fields_options[$fields_option_key])) {
$value = $langs_fields_options[$fields_option_key]['set_value'];
foreach ($langs_user_options as $user_option_key => $user_option) {
if ($user_option['set_value'] == $value) {
$user_langs[$user_option_key] = array($value);
break;
}
}
}
}
//update the user_meta field
update_user_meta($user_id, 'wpcf-support-languages', $user_langs);
}
//Now it get's easy again :)
//Update post_name (slug) with user_name (author)
//we don't want author to enter a title for his profile, this should be done automatically
$custom_title = wp_get_current_user();//get user, define where to get info from for new title
$new_title = $custom_title->user_login;//get login name from user
//collect data and define new title
$my_post = array(
'ID' => $post_id,
'post_name' => $new_title,
'post_title' => $new_title,//we NEED to do that, otherwise, AUTO DRAFT will be post name
);
// Update the post into the database
wp_update_post( $my_post );
}
}
add_action('cred_save_data', 'user_save_data_action',10,2);
