Unable to add custom select field in woocommerce - wordpress

I want to add a custom field options to checkout page. I am using the following code :
$fields['billing']['billing_options'] = array(
'label' => __('Options', 'woocommerce'),
'placeholder' => _x('', 'placeholder', 'woocommerce'),
'required' => false,
'clear' => false,
'type' => 'select',
'options' => array(
'option_a' => __('option a', 'woocommerce' ),
'option_b' => __('option b', 'woocommerce' )
)
);
I want to show the options (option_a,option_b) from database or
I want to use dynamic data and want to use for loop in the options menu
How can I use for loop inside this function ?


Just do it before, like this:
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function my_custom_checkout_fields( $fields ) {
$args = array(
'post_type' => array('options'),
'posts_per_page' => -1
);
$posts = new WP_Query($args);
$options = array();
foreach ($posts as $post) {
$options[$post->ID] => attr_esc($post->post_title);
}
$fields['billing']['billing_options'] = array(
'label' => __('Options', 'woocommerce'),
'placeholder' => _x('', 'placeholder', 'woocommerce'),
'required' => false,
'clear' => false,
'type' => 'select',
'options' => $options
);
return $fields;
}

how can i add post-categories list in elementor custom widget

My control code is
i want to create control in elementor which shows all post categories. please help me how can i achieve this...
enter image description here
$this->add_control(
'show_elements',
[
'label' => __( 'Post Categoris', 'plugin-domain' ),
'type' => \Elementor\Controls_Manager::SELECT2,
'multiple' => true,
'options' => [
$category,
],
]
); ```

You can use WP get_categories() to get all categories. check below code.
$options = array();
$args = array(
'hide_empty' => false,
);
$categories = get_categories($args);
foreach ( $categories as $key => $category ) {
$options[$category->term_id] = $category->name;
}
$this->add_control(
'show_elements',
[
'label' => __( 'Post Categoris', 'plugin-domain' ),
'type' => \Elementor\Controls_Manager::SELECT2,
'multiple' => true,
'options' => $options,
]
);

Wordpress / CMB2 Framework / Display data from repeatable fields in frontend

I have a own option-page in the backend-sidebar with this repeatable fields in it. (not a metabox) I cant figure out, how to display the data from the group field in the frontend.
function ww_register_theme_options() {
$ww_prefix = '_ww_';
$ww_contacts = new_cmb2_box( array(
'id' => $ww_prefix . 'ww_option_plugin',
'title' => esc_html__( 'Ansprechpartner', 'ww-contact' ),
'icon_url' => '/wp-content/plugins/ww-contact/assets/images/icons/ww-icon-white.png',
'object_types' => array( 'options-page' ),
'option_key' => 'ww_options',
) );
$ww_group_field = $ww_contacts->add_field(array(
'id' => $ww_prefix . 'contact_repeat_group',
'type' => 'group',
'description' => __('Ansprechparter Liste', 'ww-contact'),
'repeatable' => true,
'options' => array(
'group_title' => 'Ansprechpartner {#}',
'add_button' => __('neuer Ansprechpartner', 'ww-contact'),
'remove_button' => __('Entfernen', 'ww-contact'),
'sortable' => true,
),
));
$ww_contacts->add_group_field($ww_group_field, array(
'name' => 'Vorname',
'id' => $ww_prefix . 'forname',
'type' => 'text',
));
$ww_contacts->add_group_field($ww_group_field, array(
'name' => 'Vorname',
'id' => $ww_prefix . 'surname',
'type' => 'text',
));
}

Remove the prefix from your add_group_field ids they aren't needed. Then loop through like so...
$entries = get_post_meta( $parent, 'ww_contact_repeat_group', true );
if($entries){
foreach ( (array) $entries as $key => $entry ) {
if ( isset( $entry['forname'] ) ) {
$forname = $entry['forname'];
}
}
}

custom permalink structure for custom post type based on meta fields and custom taxonomy

I have two custom post types. One with the slug artwork and another with the slug research-materials. The permalink structure for an artwork post is http://example.com/artwork/artwork-slug and this is expected, works fine and what I want. On the post.php page for any post that is of the research-materials post type I have a custom field (via ACF) that has the slug of the artwork post that the research materials post is related to and the desired slug for the research materials post. There's also a custom taxonomy set for the research-materials post type which would play a part in the construction of the permalink structure for the research-materials posts. The permalink would look like http://example.com/artwork/related-artwork-slug/research-materials/custom-taxonomy-term/research-materials-slug
Here's the code I have so far but I'm not getting the result I'd expect... instead I'm redirected to the artwork custom post type when I should be redirected tot he research-materials custom post type single page.
Any help appreciated. Thanks in advance.

Retrieving data from additional OptionTree pages

Adding OptionTree pages is simple with the code below, but does anyone know how to retrieve the stored data?
/**

*/
add_action( 'init', 'register_options_pages' );
/**
* Registers all the required admin pages.
*/
function register_options_pages() {
// Only execute in admin & if OT is installed

// Register the pages
ot_register_settings(
array(
array(
'id' => 'custom_options',

array(

array(

'std' => '',
'type' => 'text',
'section' => 'test_section',
'class' => ''
)
)
)
)
)
)
);
I tried this $my_plugin_options = get_option('custom_options'); but it only shows the word 'array' on the front end?

This is how to retrieve the stored data:
$my_plugin_options = get_option('custom_options');
echo $my_plugin_options['test_section_input'];

Get value from option tree wordpress

I want to be use some sliders in my wordpress theme. I want to select them in my theme option. I am using the code below.
<?php
$slider_select = get_option_tree( 'slider_select', '', 'true' );
?>
<?php get_template_part('$slider_select'); ?>
But, it is not working. I want the get_template_part code worked. Any suggestion?

replace
get_template_part('$slider_select');
with
get_template_part($slider_select);

You can use this method for create a slider in option tree.
create settings array like this.
array(
'id' => 'my_slider',
'label' => 'Images',
'desc' => '',
'std' => '',
'type' => 'list-item',
'section' => 'general',
'class' => '',
'choices' => array(),
'settings' => array(
array(
'id' => 'slider_image',
'label' => 'Image',
'desc' => '',
'std' => '',
'type' => 'upload',
'class' => '',
'choices' => array()
),
array(
'id' => 'slider_link',
'label' => 'Link to Post',
'desc' => 'Enter the posts url.',
'std' => '',
'type' => 'text',
'class' => '',
'choices' => array()
),
array(
'id' => 'slider_description',
'label' => 'Description',
'desc' => 'This text is used to add fancy captions in the slider.',
'std' => '',
'type' => 'textarea',
'class' => '',
'choices' => array()
)
)
)
Add into page using loop
$my_slider = ot_get_option( 'my_slider' );
foreach($my_slider as $slider){
echo '<img src="'.$slider["slider_image"].'">';
echo $slider["slider_link"];
echo $slider["slider_description"];
}
