Adding the shortcode into WordPress Page
Automatically add posts from another WordPress website using a shortcode.
Add the shortcode [blogcrosspost url="example.com"] to desired post/page/widget and save to have the code working.
One can add some customization to the shortcode such as”:
[blogcrosspost url="example.com"][blogcrosspost number="3"][blogcrosspost readmoretext="Learn More"][blogcrosspost image_size="medium"]. Options can be medium, large, thumbnail, full or any custom size. Default is full.or use all of them in one go as:
`[blogcrosspost url="example.com" number="3" readmoretext="Learn More" image_size="medium"]```
You can also change the HTML structure using apply_filters( 'blogcrosspost_link', $html, $atts );
If you have any feedback, just write an issue. Or fork the code and submit a PR on Github.
