Page Sql: How to select the pages

With page sql, you can select pages via a select statement.

Page Sql permits to query pages in a lot of fashion.

For this example, we will select the last 5 modified howto with the following sql.

select from pages where path like ':howto%' order by date_modified desc limit 5

This query returns for this website the following pages:

Fragment: The markup to generate

When you generate content, you are looping over the same content over and over. This content part in ComboStrap is called a fragment

• For this howto, we will present our pages:
  • in a card
  • with a page image as illustration
  • with a width of 200px
  • that is clickable and centered
  • with the title, description and path variable
  • where the description is cut with the head pipeline function

<card width="250px" align="center" clickable>
   <page-image/>
   <heading 4>$title</heading>
   ${description | head(100,"...")} [[$path| ]]
</card>

• The output for the actual page is:

Sitemap

This howto shows you how to use the page sql, a fragment, the iterator and to generate a grid layout....

Iterator: Iterate over the fragment with the selected pages

The iterator is a component that

• takes the page sql
• and iterates over the fragment

The below example generate a grid that splits the horizontal space in 3 (max-line=3)

<iterator>
    <data>select from pages where path like ':howto%' order by date_modified desc limit 5</data>
    <grid max-line="3">
        <fragment>
            <box>
               <card width="250px" align="center" clickable>
                   <page-image/>
                   <heading 4>$title</heading>
                   ${description | head(100,"...")}
                   [[$path| ]]
               </card>    
            </box>
       </fragment>
    </grid>
</iterator>

The output is:
