„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.

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

and extend the lead array.

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.

AFTER

Much easier to reuse and remember :)

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

This would display the errors for anyone.

Gladly WordPress provides options to do this more subtle.

Again another Google AMP article, this time dealing with Syntax Highlighting. If you have a code centric website, this is important.

In one of my last articles I talked about a Generic Syntax Highlighter.   This time I want to show you, how to add Syntax Highlighting with GeSHi to a custom template in AMP-WP.

FIRST SOME RESOURCES

Please read up on documentation, as I am not diving into every detail.

1. AMP-WP – github.com/Automattic/amp-wp / Documentation
   The WordPress AMP integration. We will be using a custom template for our AMP pages.
2. Crayon Syntax Highlighter – github.com/aramk/crayon-syntax-highlighter
   I am using this for Syntax Highlighting on none AMP pages. It adds specific language classes to the code / pre areas, that I am using to configure GeSHi.
3. GeSHi – github.com/GeSHi/geshi-1.0
   The Syntax Highlighter
4. phpQuery – github.com/punkave/phpQuery
   DOM Document transversal & modification simplified. You should be able to apply the things below with any other tool as well.
5. My tweaks on GitHub

ADDING GESHI TO AMP-WP

1. Upload GeSHi and phpQuery to your desired location on your webserver.
2. Call the custom template for AMP-WP in your functions.php
   
   PHP

   add_filter( 'amp_post_template_file', 'xyz_amp_set_custom_template', 10, 3 ); function xyz_amp_set_custom_template( $file, $type, $post ) { if ( 'single' === $type ) { $file = dirname( __FILE__ ) . '/templates/my-amp-template.php'; } return $file; }

   1 2 3 4 5 6 7 8

   add_filter( 'amp_post_template_file', 'xyz_amp_set_custom_template', 10, 3 );   function xyz_amp_set_custom_template( $file, $type, $post ) {     if ( 'single' === $type ) {         $file = dirname( __FILE__ ) . '/templates/my-amp-template.php';     }     return $file; }

   
   I have an example stored on GitHub
3. Create a custom template in your themes folder.We could use the following filters, but its easier to use the custom template, due to the GeSHi style setup. The problem is, that the style action is called before the content action within the template. But I am planning to build a TWIG template for myself, as I am running Timber everywhere. That will detach logic and content completely, allowing to rethink some of these things and make styling a lot easier :) So watch out for my next article!
   
   add_action( 'pre_amp_render_post', 'xyz_amp_add_custom_actions' ); add_action( 'amp_post_template_css', 'xyz_amp_my_additional_css_styles' );

   1 2	add_action( 'pre_amp_render_post', 'xyz_amp_add_custom_actions' ); add_action( 'amp_post_template_css', 'xyz_amp_my_additional_css_styles' );

   
   Add this to the top of your custom template:
   
   PHP

   // Load phpQuery require ('my-libs/phpQuery/phpQuery.php'); // Load GesSHi require ('my-libs/geshi/geshi.php'); // Get AMP content and add it to phpQuery $doc = phpQuery::newDocumentHTML($this->get('post_amp_content')); $highlight = array(); // Loop through the code snippets (pre tags) foreach(pq('pre') as $snippet) { // Get classes of tag $class = pq($snippet)->attr("class"); // Check for Crayon Syntax Highlighter Class if (strpos($class, "lang:") !== false && strpos($class, "lang:default") === false) { preg_match("/lang:(?P<lang>\w+)/", $class, $catch); } else { // Fallback, if no language is detected $catch['lang'] = "php"; } // New Syntax Highlighter for each code snippet, with the correct language set // Storing for later stylesheet output. This makes also sure that stylesheets are only loaded once. $highlight[$catch['lang']] = new GeSHi(pq($snippet)->text() , $catch['lang']); // Uses Classes and no inlien styles $highlight[$catch['lang']]->enable_classes(); // Update code snippet $html = pq($snippet)->html($highlight[$catch['lang']]->parse_code()); }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

   // Load phpQuery require ('my-libs/phpQuery/phpQuery.php');   // Load GesSHi require ('my-libs/geshi/geshi.php');   // Get AMP content and add it to phpQuery   $doc = phpQuery::newDocumentHTML($this->get('post_amp_content')); $highlight = array();   // Loop through the code snippets (pre tags)   foreach(pq('pre') as $snippet) {   // Get classes of tag   $class = pq($snippet)->attr("class");   // Check for Crayon Syntax Highlighter Class   if (strpos($class, "lang:") !== false && strpos($class, "lang:default") === false) { preg_match("/lang:(?P<lang>\w+)/", $class, $catch); } else {   // Fallback, if no language is detected   $catch['lang'] = "php"; }   // New Syntax Highlighter for each code snippet, with the correct language set // Storing for later stylesheet output. This makes also sure that stylesheets are only loaded once.   $highlight[$catch['lang']] = new GeSHi(pq($snippet)->text() , $catch['lang']);   // Uses Classes and no inlien styles   $highlight[$catch['lang']]->enable_classes();   // Update code snippet   $html = pq($snippet)->html($highlight[$catch['lang']]->parse_code()); }

   
   I have an example stored on GitHub. The above works, if you are using Crayon Syntax Highlighter for standard pages.
   If you use something else, this needs to be changed.
4. Add the GeSHi styles to the amp-custom style tag
   
   
   PHP

   <style amp-custom> <?php $this->load_parts( array( 'style' ) ); ?><?php do_action( 'amp_post_template_css', $this ); // Load Stylesheets for highlighted languages foreach($highlight as $store){ echo $store->get_stylesheet(); } ?> </style>

   1 2 3 4 5 6 7 8 9 10 11 12

   <style amp-custom> <?php $this->load_parts( array( 'style' ) ); ?><?php do_action( 'amp_post_template_css', $this );      // Load Stylesheets for highlighted languages foreach($highlight as $store){   echo $store->get_stylesheet(); } ?> </style>

   
   I have an example stored on GitHub.
5. Output updated amp-wp-content
   
   
   PHP

   <div class="amp-wp-content"> <h1 class="amp-wp-title"><?php echo wp_kses_data( $this->get( 'post_title' ) ); ?></h1> <ul class="amp-wp-meta"> <?php $this->load_parts( apply_filters( 'amp_post_template_meta_parts', array( 'meta-author', 'meta-time', 'meta-taxonomy' ) ) ); ?> </ul> <?php echo $doc->html(); // amphtml content; no kses ?> </div>

   1 2 3 4 5 6 7

   <div class="amp-wp-content"> <h1 class="amp-wp-title"><?php echo wp_kses_data( $this->get( 'post_title' ) ); ?></h1> <ul class="amp-wp-meta"> <?php $this->load_parts( apply_filters( 'amp_post_template_meta_parts', array( 'meta-author', 'meta-time', 'meta-taxonomy' ) ) ); ?> </ul> <?php  echo  $doc->html();  // amphtml content; no kses ?> </div>

   
   I have an example stored on GitHub.
6. Save and check that your AMP page validates, by adding #development=1 to the end of the url. Check the console for errors.
   Show this page as AMP

Google’s AMP is here to save us from slow mobile content delivery, by enforcing strict standards and limiting what is allowed within AMP pages. The pages only allow a subset of tags and introduce their own tags for fast prefetching of content (images, videos … AMP Specs)

THIS IS AMP

„The Accelerated Mobile Pages (“AMP”) Project is an open source initiative that came out of discussions between publishers and technology companies about the need to improve the entire mobile content ecosystem for everyone – publishers, consumer platforms, creators, and users.

Today, the expectation is that content should load super fast and be easy to explore. The reality is that content can take several seconds to load, or, because the user abandons the slow page, never fully loads at all. Accelerated Mobile Pages are web pages designed to load instantaneously – they are a step towards a better mobile web for all.“

AMP CACHE & VALIDATION

AMP pages are cached within the AMP Cache, providing even faster delivery of your content. The core libs validate your implementation and highlight any problems by pushing errors to the console.

INTEGRATION

The documentation lists all components currently supported within a page and experimental components in development as well.

1. Introduction to AMP
2. Video Introduction
3. AMP for WordPress
4. AMP Docs
5. Q&A Video

I have already added AMP support to our blog posts:

1. Standard page
2. AMP page

Google’s Webmaster Tools also integrates a new section for AMP, to see how they perform.

WHAT AMP IS NOT

AMP is not supposed to replace your webpage, but offer a faster access point to presented content. It will not solve all use cases, but offer better performance for your simple reading pleasure for now. Its a start and lets see how it evolves ;)
