I'm trying to add a wordpress filter to the posting area:

AndIwantedtoseeonlypoststhathavethisfunctionapplied:

functionag_display_custom_meta_box($post){wp_nonce_field('ag_featured_custom_box','ag_featured_custom_box_nonce');$stored=get_post_meta($post->ID,'_ag_featured_post',true);$options=array('0'=>'Nãousarmatériacomodestaque','principal'=>'Grande','secundaria'=>'Pequenos','slider'=>'Slider','colunaaposentados'=>'ColunaAposentados','colunaunidades'=>'ColunaUnidades','colunaeventos'=>'ColunaEventos','colunaesportes'=>'ColunaEsportes','colunanoticias'=>'ColunaNoticias','colunafenae'=>'ColunaFenae');$output="<select name='ag_featured_post_position'>";

foreach ($options as $value => $title):

    $output .= "<option ";

    if(esc_attr($stored) == $value)
        $output .= "selected='selected' ";

    $output .= "value='{$value}'>{$title}</option>";

endforeach;

$output .= "</select>";

echo $output;

}

/**
* @param $post_id
*/
function ag_save_meta_box( $post_id ) {

// Validations
$nonce = $_POST['ag_featured_custom_box_nonce'];

if(!isset($_POST['ag_featured_post_position']) || !wp_verify_nonce($nonce, 'ag_featured_custom_box'))
    return $post_id;

if(defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE)
    return $post_id;

// Check the user's permissions
if ( 'page' == $_POST['post_type'] ) {
    if ( ! current_user_can( 'edit_page', $post_id ) ) {
        return $post_id;
    }
} else {
    if ( ! current_user_can( 'edit_post', $post_id ) ) {
        return $post_id;
    }
}

update_post_meta( $post_id, '_ag_featured_post', sanitize_text_field( 
$_POST['ag_featured_post_position']));
}

add_action('save_post', 'ag_save_meta_box');

I've read something about add_filter , but I do not know where to apply and where to put exactly ...

The exact use of this filter is: on my site there is a 'highlight' area that uses this function to choose what goes and what does not go there ... the problem that I have countless daily posts and are not all that go to the spotlight, and the posting staff would like to filter only the ones that stand out ... and I do not know how to do that.

As it is in wordpress the doc I read commented on being in the function.php file

php wordpress

Misuse of function or logic poorly implemented? Only uppercase and lowercase letters and accents in regular expressions [duplicate]

The function you are looking for is add_screen_option

To add the option you can do

function add_screen_option(){
    $option = 'per_page';

    $args = array(
        'label' => 'Movies',
        'default' => 10,
        'option' => 'cmi_movies_per_page'
    );

    add_screen_option( $option, $args );
}

within init for example.

add_action( 'init', 'add_screen_option' );

See this tutorial for even more details.
