custom module - choose the blog

[giozua]

Hi, I'm creating a custom module to have a slider post.
I need to choose the blog from a list and have the number of posts to display. The syntax to set the blog is this: {% set posts = blog_recent_posts('default', 5) %} but how do I make dynamic the field "default" = blog name or its id, and the field "5" = number of posts to be displayed?

I've tried with this sintax

{% set posts = blog_recent_posts('{{widget.blog_name}}', '{{widget.n_posts}}') %}

but do not work

Can anyone help me?

Many thanks

Giovanni

How are you wanting to edit this? from the page editor?

You could create editable fields: 

{% text "blog_id" label="Blog ID", value="12345678", export_to_template_context=True %}

{% set post_num = [1, 2, 3, 4, 5, 6] %}
{% choice "blog_limit" label="Number of Posts", value="5", choices="{{ post_num }}", export_to_template_context=True %}

Then assign the values to the blog search funtion:

{% set posts = blog_recent_posts('{{ widget_data.blog_id.value }}', '{{ widget_data.blog_limit.value }}') %}

this would create editable fields on the editing page. You would put the blog ide in the text field, and use the choice dropdown to choose the blog limit. 

Let me know if this is what you need and if it works.

{% choice "blog_limit" label="Number of Posts", value="5", choices="{{ post_num }}", export_to_template_context=True %}

{% set posts = blog_recent_posts('{{ widget_data.blog_id.value }}', '{{ widget_data.blog_limit.value }}') %}

<p>{{ widget_data.blog_id.value }}</p>

Hi Gio,

When you are within a HubL statement, it is not necessary to wrap HubL tokens in expression delimiters

{{ }}

 Making these slight changes to your code should get this working

{% text "blog_id" label="Blog ID", value="4495212459", export_to_template_context=True %}
{% set post_num = [1, 2, 3, 4, 5, 6] %}
{% choice "blog_limit" label="Number of Posts", value="5", choices="post_num", export_to_template_context=True %}
{% set posts = blog_recent_posts(widget_data.blog_id.value, widget_data.blog_limit.value) %}

Best,

Danielle

Ok this is very strange, because inside a custom modul the script don't work instead directly inside hubl module this work fine!!! Yeah

Thanks a lot

Your creating a array. To get the data from it you have to loop through it with a for loop. {% for post in posts %}{% endfor %}

Then you access the data by targeting post. {{ post.name }} post being the single item name in the for loop.
