Gutenberg Block Development: Only one RichText content is saving

Question

I added two RichText components in my block.

registerBlockType( 'hallmark/gray-content-container', {
        title: __( 'Gray Content Container' ),
        icon: 'grid-view',
        category: 'hallmark-blocks',
        keywords: [
            __( 'Hallmark gray content' ),
            __( 'Hallmark' ),
            __( 'Gray content container' ),
        ],

        attributes:{
            contentHeading: {
                type: 'string',
                source: 'children',
                selector: 'h1,h2,h3,h4,h5,h6'
            },
            textContent: {
                type: 'string'
            }
        },

        edit: function( props ) {

            var textContent = props.attributes.textContent;
            var contentHeading = props.attributes.contentHeading;

            function onChangeTextContent( content ) {
                props.setAttributes( { textContent: content } );
            }

            function onChangeHeading (heading) {
                props.setAttributes( { contentHeading: heading} );
            }

            return (
                <div className={ props.className }>
                    <label className="editor-content-section-label">Content for gray section</label>
                    <RichText
                        tagName="h1"
                        value={contentHeading}
                        onChange={onChangeHeading}
                        placeholder={ __( 'Add a heading' ) }
                        keepPlaceholderOnFocus
                    />
                    <RichText
                        tagName="p"
                        className={props.className}
                        onChange={onChangeTextContent}
                        value={textContent}
                        placeholder={ __( 'Add content' ) }
                        keepPlaceholderOnFocus
                    />
                </div>
            );
        },

        save: function( props ) {
            //return null;
            return(
                <div className={props.className}>
                    <div className="gray-bg">
                        <div className="constrain content">
                            <RichText.Content tagName="h1" value={ attributes.contentHeading } />
                            <RichText.Content tagName="p" value={ attributes.textContent } />
                        </div>
                    </div>
                </div>
            );

        },
    } );

I tried two different approaches to save the data.

Using default save() function

save: function( props ) {
      return(
         <div className={props.className}>
            <div className="gray-bg">
                <div className="constrain content">
                    <RichText.Content tagName="h1" value={ attributes.contentHeading } />
                    <RichText.Content tagName="p" value={ attributes.textContent } />
                 </div>
            </div>
         </div>
     );
},

Saving it in PHP:

Using render_callback method (Using return null; from block's default save() function.

register_block_type( 'hallmark/white-content-container', array(
    'render_callback' => 'hall_render_white_content'
) );

function hall_render_white_content( $atts ) {
   $heading = $atts['contentHeading'];
   $raw_content = $atts['textContent'];
   $full_content = $heading . $raw_content;
   // var_dump($full_content);

   $content = hall_clean_shortcode_block_content( $full_content );

   return '<div class="gray-bg"><div class="constrain content">' . $content . '</div></div>';
}

atts['contentHeading'] element does not exist at all in $atts array. When I check var_dump( $attas ); it has textContentelement present.

The problem is both approaches are only saving the textContent. contentHeading is not at all saving.

What I am missing?

Answer 1

For debugging use console.log(props.attributes) inside your edit function and observe if the values of contentHeading is changing or not when you edit. edit() function will be called each time if the state or props of component changes. As per my lucky guess the source of contentHeading should be 'text' instead of children.
