Custom divi builder child module not rendering - php

Question

I am trying to create some custom Divi builder modules.
I followed the sparse documentation at their website, trying to create a module and a child module. Everything seems to be working fine, but the rendering.
It is just rendering the module shortcode as a string, and not the content.
Current code of the parent module is
class DEDE_Cards extends ET_Builder_Module {
public function init(){
$this->name = esc_html__('Custom Card', 'dede-designvox-divi-extension');
$this->plural = esc_html__('Custom Cards', 'dede-designvox-divi-extension');
$this->main_css_element = 'cards-wrapper';
$this->slug = 'dede_cards';
$this->vb_support = 'on';
$this->child_slug = 'dede_card_item';
}
public function get_fields(){
return array(
'title' => array(
'label' => esc_html__( 'Title', 'dede-designvox-divi-extension' ),
'type' => 'text',
'toggle_slug' => 'main_content',
'description' => esc_html__( 'Type the section title' ),
),
'card_title_position' => array(
'label' => esc_html__( 'Title Position', 'dede-designvox-divi-extension' ),
'type' => 'select',
'options' => array(
'overlay' => esc_html__( 'Overlay', 'et_builder' ),
'top' => esc_html__( 'Over image', 'et_builder' ),
'bottom' => esc_html__( 'Under image', 'et_builder' ),
),
'toggle_slug' => 'main_content',
'description' => esc_html__( 'Here you can choose the position of the card title', 'dede-designvox-divi-extension' ),
'default_on_front' => 'bottom',
),
);
}
function before_render() {
global $dede_card_item_number;
$dede_card_item_number = 1;
}
public function render($unprocessed_props, $content = null, $render_slug ){
global $dede_card_item_number;
return sprintf(
'<div>%1$s</div>',
$this->content
);
}
public function add_new_child_text() {
return esc_html__( 'Add New Card Item1', 'dede-designvox-divi-extension' );
}
}
new DEDE_Cards;
And then the child module
class DEDE_Card_Item extends ET_Builder_Module {
public function init(){
$this->name = esc_html__('Custom Card', 'dede-designvox-divi-extension');
$this->plural = esc_html__('Custom Cards', 'dede-designvox-divi-extension');
$this->type= 'child';
$this->child_title_var = 'title';
$this->no_render = true;
$this->slug = 'dede_card_item';
$this->vb_support = 'on';
}
public function get_fields(){
return array(
'title' => array(
'label' => esc_html__('Title', 'dede-designvox-divi-extension'),
'type' => 'text',
'description' => esc_html__('The title of this card', 'dede-designvox-divi-extension'),
'toggle_slug' => 'main_content',
),
'desc' => array(
'label' => esc_html__( 'Description', 'dede-designvox-divi-extension' ),
'type' => 'textarea',
'description' => esc_html__( 'The card description' ),
'toggle_slug' => 'main_content',
),
'src' => array(
'label' => esc_html__( 'Image', 'dede-designvox-divi-extension'),
'type' => 'upload',
'description' => esc_html__( 'Upload your desired image, or type in the URL to the image', 'dede-designvox-divi-extension'),
'upload_button_text' => esc_attr__('Upload an image', 'dede-designvox-divi-extension'),
'choose_text' => esc_attr__('Choose an Image', 'dede-designvox-divi-extension'),
'update_text' => esc_attr__('Set as Image', 'dede-designvox-divi-extension'),
'affects' => 'alt',
'toggle_slug' => 'main_content',
),
'alt' => array(
'label' => esc_html__( 'Image Alternative Text', 'dede-designvox-divi-extension' ),
'type' => 'text',
'depends_show_if' => 'on',
'depends_on' => array(
'src',
),
'description' => esc_html__( 'This defines the HTML ALT text. A short description of your image can be placed here.', 'dede-designvox-divi-extension' ),
'toggle_slug' => 'main_content',
),
'url' => array(
'label' => esc_html__( 'Link URL', 'dede-designvox-divi-extension' ),
'type' => 'text',
'description' => esc_html__( 'Enter the link that you would like this card to direct to.', 'dede-designvox-divi-extension' ),
'toggle_slug' => 'main_content',
),
);
}
}
new DEDE_Card_Item;
The shortcode is just being rendered as a string on the website, like:

Answer 1

You just have to leave out the line $this->no_render = true; and then implement the function render in the child Module.

Answer 2

I try to create the same module to add child items inside module. But I have another problem, when I click add child item I get the empty popup ((( like this https://prnt.sc/156jfev. I tried the same code as author

Answer 3

it's working for me you can try it,

Answer 4

I was having similar issue to Mikael, where the child's setting looked like:
Just in case anyone is having similar issue, i realised its because the child's module wasn't being loaded. Since i was using a custom extension, there was a file called loader.phpin my extension that was responsible for loading the module files and it was loading the parent module file but skipping the child because of the pesky if statement with preg_match.
$module_files = glob( __DIR__ . '/modules/**/*.php' );
foreach ( (array) $module_files as $module_file ) {
if ( $module_file && preg_match( "/\/modules\/\b([^\/]+)\/\\1\.php$/", $module_file ) ) {
require_once $module_file;
}
}
if you replace it with:
foreach ( (array) $module_files as $module_file ) {
// if ( $module_file && preg_match( "/\/modules\/\b([^\/]+)\/\\1\.php$/", $module_file ) ) {
require_once $module_file;
//}
}
then it worked for me :)
Really hope that saves someone the 3 hours of debugging i spent.
