Paw – essential HTTP client to test your APIs

Paw is a full-featured HTTP client that lets you test the APIs you build or consume. It has a beautiful native OS X interface to compose requests, inspect server responses and generate client code out-of-the-box.

This is one of my go-to tools, when test-driving my API endpoints.

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

When performing tasks using the Gravity Forms API, handling notifications and hook execution on demand is something that becomes really handy.

<?php

trait GravityForm{
	
	
	function GravityForm_send_notifications($form_id, $entry_id){

	  // Get the array info for our forms and entries
	  // that we need to send notifications for
  
	  $form 	= RGFormsModel::get_form_meta($form_id);
	  $entry 	= RGFormsModel::get_lead($entry_id);
  
	  // Loop through all the notifications for the
	  // form so we know which ones to send
  
	  $notification_ids = array();
  
	  foreach($form['notifications'] as $id => $info){
  
		  array_push($notification_ids, $id);
  
	  }
  
	  // Send the notifications
  
	  GFCommon::send_notifications($notification_ids, $form, $entry);

	}
	
	function GravityForm_execute_hooks($form_id, $entry_id){
	
	
		$form 				= GFAPI::get_form( $form_id );
		$entry 				= GFAPI::get_entry( $entry_id );
		$registered_addons 	= GFAddOn::get_registered_addons( );
		
		foreach( $registered_addons as $reg){
			if(method_exists($reg, "get_instance")){
				
				$execute = $reg::get_instance();				
				
				foreach($registered_addons as $addon){					
					
					$execute->maybe_process_feed( $entry, $form);
				}
			}
		}
		
		return true;
	}
		
	
}

<?php

trait GravityForm{

function GravityForm_send_notifications($form_id, $entry_id){

// Get the array info for our forms and entries

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;

}

A sandbox for WordPress plugin updates … WP Safe Updates

WP Safe Updates allows users to test plugin updates in a sandbox before applying them on a live site.

The plugin tells WordPress to temporarily use a different database prefix and a different plugins directory while in the alternative sandbox.

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 :)

Debugging WordPress plugins on a live website

Sometimes we need to debug a WordPress plugin, even though the website is live.

This would display the errors for anyone.

define('WP_DEBUG', true);

1	define('WP_DEBUG', true);

Gladly WordPress provides options to do this more subtle.

// Turns WordPress debugging on
define('WP_DEBUG', true);
 
// Tells WordPress to log everything to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);
 
// Doesn't force the PHP 'display_errors' variable to be on
define('WP_DEBUG_DISPLAY', false);
 
// Hides errors from being displayed on-screen
@ini_set('display_errors', 0);

// Turns WordPress debugging on

define('WP_DEBUG', true);

// Tells WordPress to log everything to the /wp-content/debug.log file

define('WP_DEBUG_LOG', true);

// Doesn't force the PHP 'display_errors' variable to be on

define('WP_DEBUG_DISPLAY', false);

// Hides errors from being displayed on-screen

@ini_set('display_errors', 0);
