Output a Raw Views Loop

Sometimes we need to populate values in as example Select fields (JSON) or of 3rd Party ShortCodes that generate charts or similar.
This snippet allows you to output a given Views Loop without default HTML wrapped around the results.

The following snippet produces a clean View output, or as clean as we can:

add_filter( 'wpv_filter_wpv_view_shortcode_output', 'prefix_clean_view_output', 5, 2 );

function prefix_clean_view_output( $out, $id ) {
if ( $id == '375' ) {
$start = strpos( $out, '<!-- wpv-loop-start -->' );
if ( 
$start !== false
&& strrpos( $out, '<!-- wpv-loop-end -->', $start ) !== false
) {
$start = $start + strlen( '<!-- wpv-loop-start -->' );
$out = substr( $out , $start );
$end = strrpos( $out, '<!-- wpv-loop-end -->' );
$out = substr( $out, 0, $end );
}
}
return $out;
}

Use a Views Loop similar to the below:

Step by step:

  • It hooks early in the View output.
  • Priority 5 is mandatory as we already do some other cleaning at priority 10.
  • It only affects a View with an ID of 375, adjust acordingly if needed.
  • It only affects Views with actual results: if the View matches no result, the same “No items found” or whatever you have between the wpv-no-items-found shortcode applies.
  • It returns only what is between the HTML comments <!– wpv-loop-start –> and <!– wpv-loop-end –> , excluding them. Only content between those HTML comments is returned, as is.

Notice that, with this applied to a given View ID:

  • Pagination, specially AJAX pagination, will not work.
  • Parametric search, specially AJAXed parametric search, will not work.
  • Other future features will not work either.

So this is to be used if and only if you know what you are doing and you are going to use the View output as source for anything else.

But also notice that this only clears the View structure.

Building as example JSON inside a View output is wrong because we can not address quoting problems.

Please use this with caution, explaining the side effects and rsponsibly.

Update User Profile with CRED, with CheckBoxes

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);

Update post title/name with a Date from a Types Date CF

Update post title/name with a Date taken from a types Date CF (and obviously you won’t 2664748859 as title but 11-06-2014 or similar) with CRED hook. Remember that Toolset uses Timestamp but you want a “normal” date as Post Title.

function ttd_save_data_action($post_id, $form_data){
            // Change your CRED Form "ID" accordingly below
            if ($form_data['id']==ID){
               
                //Declare the content of your variables, change "your_custom_field_slug" accordingly
                $custom_value = get_post_meta( $post_id, 'wpcf-your_custom_field_slug', true );//get posts' Date field value (timestamp)
                $custom_title = gmdate("m-d-Y", $custom_value);//convert timestamp to m-d-y for output
                //collect data and define new title
                $my_post = array(
                    'ID'               => $post_id,
                    'post_title'   => $custom_title,
                    'post_name' => $custom_title,
                   
                );
               
                // Update the post into the database
                wp_update_post( $my_post );
               
            }
        }
    add_action('cred_save_data', 'ttd_save_data_action',10,2);

Evaluate for recurring Date

This creates a ShortCode to use when Date CF (Timestamps) need to be evaluated by recurring dates, just as for Birthdays.

Create a CPT, associate a Date CF to it, list CPT in a View and see in the code how to evaluate.
Remember to Register the ShortCode in Views Settings.

function born_today_func( $atts ) {
    extract(shortcode_atts(array(
        'birthday' => get_post_meta(get_the_ID(), 'wpcf-your_slug', true),
 
    ), $atts)
           );
 
    if(((date('d', $birthday)) == date('d')) && (date('m', $birthday)) == date('m')){
        return 1;
    }else{
        return 0;
    }
}
add_shortcode( 'born-today', 'born_today_func' );

Evaluate like this in your view loop:
