Add numbers to the listing

Hi,

You can easily add additional characters to the index, such as numbers, by hooking the filter called a-z-listing-alphabet which lists every character class separated by commas ,. You just need to add the additional characters to the end to include numbers last in your index page:

add_filter( 'a-z-listing-alphabet', 'your_alphabet_filter' );

function your_alphaber_filter( $alphabet ) {
    return $alphabet . ',1,2,3,4,5,6,7,8,9,0';
}

You could also combine all numbers together, while keeping other unknown characters separated by returning something along the lines of:

return $alphabet . ',#1234567890';

That will case all numbers to be listed under the heading of #. If you do this you will probably want to hook the filter a-z-listing-non-alpha-char to replace the default non-alphabetic heading which defaults to also be #:

add_filter( 'a-z-listing-non-alpha-char', function() { return 'Non-alphanumeric'; }

I don’t get this, please help

Hi,

I have the same problem, some posts begins with a number and are not listed in the index.

i added this code in my function.php

add_filter( 'a-z-listing-alphabet', 'your_alphabet_filter' );

function your_alphaber_filter( $alphabet ) {
    return $alphabet . ',1,2,3,4,5,6,7,8,9,0';
}

but it doesn’t work.

what code should i use ? and in which file(s) ?

Sorry, I made a mistake in my examples.. The hyphens in the filter name a-z-listing-alphabet need to be underscores:

add_filter( 'a_z_listing_alphabet', 'your_alphabet_filter' );

I’m working on updating the plugin to allow both formats so that it doesn’t matter, but until then you need _s.
