Automatic generation of "featured pages"?

Hi @fridde,
I understand that you need to replace your 6 featured pages dynamically by your 6 lasts featured posts.
Here’s what I would do :
1) Create a function to store the last 6 featured posts ids in an array, either in a global var or a class property by looping on a get_posts() array of posts objects.
2) Use the ‘tc_fp_id’ filter to override the default behaviour and assign the wanted post id to each single featured pages (with a switch…case on $fp_single_id var for example : case ‘one’, case ‘two’, …, case 6)

Hope this helps!

Yes, that helped me very much! Thank you! Also, I have understood more about how your code is written.

Well, to be honest, I still have one minor problem. I wanted to implement your idea of the switch-case, but the value passed to the hook “tc_fp_id” is not “one”, “two”, “three” etc, but the actual id of the chosen post/page returned by tc__f( '__get_option' , 'tc_featured_page_'.$fp_single_id) (line 136 in class-content-featured_pages.php).

My code in functions.php looks like this:

remove_all_filters('tc_fp_id');
remove_all_filters('tc_featured_pages_ids');

function custom_fp_ids_array(){
    return array( 'one' , 'two' , 'three' , 'four', 'five', 'six');
}

function return_custom_ids($value){
    echo $value . "<br>";

    //insert switch-case here, but since the value is not the expected,
    // I simply return "1" to see that the rest works.
    // Post 1 does exist

    return 1;
}

add_filter('tc_featured_pages_ids', 'custom_fp_ids');

The output created by echo $value is 24, 5, 0 …, the id’s corresponding to the posts I have chosen in the settings.
Of course, a workaround would be to simply chose certain posts as the featured posts in customizrs settings-menu and build the switch-case around the id’s of these posts. But the, of course, some unfortunate future admin could do changes in the customizr-settings not knowing that he/she just destroyed my workaround.

Any idea what I have been missing or mixing up? I have followed the “road” of $fp_single_id, and yes, I expect it to be “one” or “two” etc, but I can’t see why it has changed to the numerical correspondent BEFORE entering my custom filter. Maybe you can see it directly.

Hi @friddle,
the filter is written as follow :

$featured_page_id               = apply_filters( 'tc_fp_id', esc_attr( tc__f( '__get_option' , 'tc_featured_page_'.$fp_single_id) ), $fp_single_id );

You are right, the filtered value is :

esc_attr( tc__f( '__get_option' , 'tc_featured_page_'.$fp_single_id) )

but you can access the second parameter of the filter, which is the one you need :

$fp_single_id

This type of code will do the trick (note that I set 2 parameters in the filter declaration) :

add_filter( 'tc_fp_id' , 'my_forced_id' , 10 , 2 );
function my_forced_id ( $fp_database_id, $fp_text_id ) {
	//declare your array of featured POST that you get with a function
	//in my example it should look like a simple array of numerical post ids $posts_to_feature = array( post_id_1, post_id_2, ...);
	$posts_to_feature 		= get_my_posts_to_feature();//this function could use for example get_posts() for example to fetch your featured posts. you can also build a custom query with a class instanciation like $my_query = new WP_query;

	//get your custom fp array
	$custom_fp_ids_array 	= custom_fp_ids_array();

	//loop on the fp id array
	//check if tc_fp_id exists in fp custom array (safer) and returns the custom post id sharing the same key
	while( $el = current($custom_fp_ids_array) ) {
	    $fp_key =  key($custom_fp_ids_array);
	    if ( isset($custom_fp_ids_array[$fp_key]) && $fp_text_id == $custom_fp_ids_array[$fp_key] )
	     	return $posts_to_feature[$fp_key];
	    //if no match found, then loop to the next item
	    next($test);
	}

	//if no match was found, then return the original value.
	return $fp_database_id;
}

I did not test it but this should hopefully not be too far from what you need.

That was it! Thanks!

I had actually tested

function return_custom_id($value, $secondvalue){
    echo $value . "<br>";
    echo $secondvalue . "<br>";
    return 1;
}
add_filter('tc_fp_id', 'return_custom_id');

but had only gotten an error saying Warning: Missing argument 2 for return_custom_ids. So I made the assumption that there was no second argument created.

Thanks to your hint that add_filter should actually declare how many arguments that are sent, I immediately could build a working function.

You can’t imagine my thankfulness! I’ll convince the board of my club to grant a donation.

Cool.
Donation, do what you want but hey, you don’t have to!
