Generate Unique User Nicenames for WordPress

Simple little snippet, that can easily be used in conjunction with wp_update_user()

/* Generate Unique User Nicename */
function generate_unique_user_nicename( $x ) {
	// set up args to query
	$args = array(
		'search'         => sanitize_title( $x ),
		'search_columns' => array( 'user_nicename' )
	);
	// query for user
	$user_url_exists = new WP_User_Query( $args );
	$results = $user_url_exists->get_results();
	// if user url is found, check for new one
	if( !empty( $results ) ) {
		$i = substr( sanitize_title( $x ), intval( strrpos( sanitize_title( $x ) ,'-' ) ) + 1 ); 
		if( is_numeric( $i ) ) {
			$i++;
			$y = substr($x, 0, strrpos($x,'-' ));
			$company_name = $y . '-' . $i;
		} else {
			$company_name = $x . '-1';
		}
		$new_company_name = sanitize_title( $company_name );
		return generate_unique_user_nicename( $new_company_name );
	} else {
		return sanitize_title( $x );
	}
}

/* Generate Unique User Nicename */

Cleaning up the WordPress Feed (Validation)

When using your main content feed to share posts via buffer or other services, it is crucial that your feed validates cleanly.

There are always things in the generated WordPress content that can break your feed validation. Here some things to cleanup or alter your delivered feed content.

CONDITIONAL TAGS

is_feed()
Check for syndication request. This tag is not typically used by users; it is used internally by WordPress and is available for Plugin Developers.

Check for feed syndication in your themes functions.php

if (is_feed()) {
    /.. tweaks go here ../
}

if (is_feed()) {

/.. tweaks go here ../

}

REMOVE IFRAMES

function rss_noiframe($content) {
        
    $content = preg_replace( '/<iframe(.*)\/iframe>/is', '', $content );

    return $content;
}

add_filter('the_excerpt_rss', 'rss_noiframe');
add_filter('the_content_feed', 'rss_noiframe');

function rss_noiframe($content) {

$content = preg_replace( '/<iframe(.*)\/iframe>/is', '', $content );

return $content;

}

add_filter('the_excerpt_rss', 'rss_noiframe');

add_filter('the_content_feed', 'rss_noiframe');

REMOVE / DISABLE COMMENTS

function rss_nocomments($content) {
    
     global $post;
      $post->comment_status="closed";
   
  
}

add_filter('the_excerpt_rss', 'rss_nocomments');
add_filter('the_content_feed', 'rss_nocomments');

function rss_nocomments($content) {

global $post;

$post->comment_status="closed";

}

add_filter('the_excerpt_rss', 'rss_nocomments');

add_filter('the_content_feed', 'rss_nocomments');

REMOVE RESPONSIVE IMAGES

The sizes attribute breaks feed validation, here how to clean it up.

function no_responsive_image_feeds() {
    add_filter( 'max_srcset_image_width', function() {
       return 1;
    } );
}

add_action('rss2_head', 'no_responsive_image_feeds' );
add_action('atom_head', 'no_responsive_image_feeds' );
add_action('rss_head', 'no_responsive_image_feeds' );

function no_responsive_image_feeds() {

add_filter( 'max_srcset_image_width', function() {

return 1;

} );

}

add_action('rss2_head', 'no_responsive_image_feeds' );

add_action('atom_head', 'no_responsive_image_feeds' );

add_action('rss_head', 'no_responsive_image_feeds' );

INCLUDE PAGES IN POST FEED

if (is_feed()) {
function feedFilter($query) {
	if ($query->is_feed) {
		$query->set('post_type','any');
		}
	return $query;
}
add_filter('pre_get_posts','feedFilter');
}

if (is_feed()) {

function feedFilter($query) {

if ($query->is_feed) {

$query->set('post_type','any');

}

return $query;

}

add_filter('pre_get_posts','feedFilter');

}

ADJUST AMOUNT OF POSTS

if (is_feed()) {

function feedFilter($query) {
	if ($query->is_feed) {
		$query->set('posts_per_page','11');
	}
 
	return $query;
}
add_filter('pre_get_posts','feedFilter');

}

if (is_feed()) {

function feedFilter($query) {

if ($query->is_feed) {

$query->set('posts_per_page','11');

}

return $query;

}

add_filter('pre_get_posts','feedFilter');

}

LIMIT BY CATEGORY

if (is_feed()) {
function feedFilter($query) {
	if ($query->is_feed) {
		$query->set('category_name', 'my-special-cat');
	}
 
	return $query;
}
add_filter('pre_get_posts','feedFilter');
}

if (is_feed()) {

function feedFilter($query) {

if ($query->is_feed) {

$query->set('category_name', 'my-special-cat');

}

return $query;

}

add_filter('pre_get_posts','feedFilter');

}

Gravity Forms PHP Trait to send notifications and execute hooks on demand

WP REST API rendered output & Visual Composer

Visual Composer shortcodes are normally not converted within the WordPress REST API rendered output.

This can be accomplished by calling WPBMap::addAllMappedShortcodes();

add_action( 'rest_api_init', function ()
{
   register_rest_field(
          'page',
          'content',
          array(
                 'get_callback'    => 'convert_do_shortcodes',
                 'update_callback' => null,
                 'schema'          => null,
          )
       );
});

function convert_do_shortcodes( $object, $field_name, $request )
{
   WPBMap::addAllMappedShortcodes(); // This does all the work

   global $post;
   $post = get_post ($object['id']);
   $output['rendered'] = apply_filters( 'the_content', $post->post_content );

   return $output;
}

add_action( 'rest_api_init', function ()

{

register_rest_field(

'page',

'content',

array(

'get_callback' => 'convert_do_shortcodes',

'update_callback' => null,

'schema' => null,

)

);

});

function convert_do_shortcodes( $object, $field_name, $request )

{

WPBMap::addAllMappedShortcodes(); // This does all the work

global $post;

$post = get_post ($object['id']);

$output['rendered'] = apply_filters( 'the_content', $post->post_content );

return $output;

Query Leads from Gravity Forms

„Gravity Forms for WordPress is a full featured contact form plugin that features a drag and drop interface, advanced notification routing, lead capture, conditional logic fields, multi-page forms, pricing calculations and the ability to create posts from external forms.“

There are multiple options how to handle the confirmation page. Gravity form allows you to send query parameters to the page it is redirecting to.

You can send all form information in the clear, via query variables, but that looks really messy. Its better to use something like this .. lead_id={entry_id} and query form information on the actual confirmation page.

GET THE LEAD

This will output the submitted form data as an array, with all fields linked by field id.

$lead_id = intval( $_GET['lead_id'] );
$lead = RGFormsModel::get_lead($lead_id);

1 2	$lead_id = intval( $_GET['lead_id'] ); $lead = RGFormsModel::get_lead($lead_id);

TRANSLATE FIELD IDS TO FIELD LABELS

When you are reusing the field data for your own purposes, its easier to deal with field names than with fields ids. So we get the form meta data

$form = RGFormsModel::get_form_meta( $lead['form_id'] );

foreach( $form['fields'] as $field ) {

 $values[$field['id']] = array(
        'id'    => $field['id'],
        'label' => $field['label'],
        'value' => $lead[ $field['id'] ],
 );
}

$form = RGFormsModel::get_form_meta( $lead['form_id'] );

foreach( $form['fields'] as $field ) {

$values[$field['id']] = array(

'id' => $field['id'],

'label' => $field['label'],

'value' => $lead[ $field['id'] ],

);

}

and extend the lead array.

foreach($lead as $key => $val){
 if(is_numeric($key)){
  $lead_key = str_replace(" ", "_", strtolower($values[$key]['label']));
  $lead[$lead_key] = $val;	
 }
}

foreach($lead as $key => $val){

if(is_numeric($key)){

$lead_key = str_replace(" ", "_", strtolower($values[$key]['label']));

$lead[$lead_key] = $val;

}

Before you needed to know the actual field id to get its value. Now you can use the generated lead key to get that value.

BEFORE

$field_key = 10;
echo $lead[$field_key];

1 2	$field_key = 10; echo $lead[$field_key];

AFTER

$field_key = "e-mail";
echo $lead[$field_key];

1 2	$field_key = "e-mail"; echo $lead[$field_key];

Much easier to reuse and remember :)
