Passing URL parameters to WordPress pages and pretty url

Question

I create shortcode like this

function test_func( $atts ) {   

    return $_GET['myvar'];
}
add_shortcode( 'test', 'test_func' );

and one page with this name myparameters

so this is the final url

http://website.com/myparameters

if I try this works perfect

http://website.com/myparameters/?myvar=theparameter

But i like have pretty url or friendly url like this

http://website.com/myparameters/theparameter/

But show page not found.

I try some tutorial like this LINK but nothing happen

Answer 1

You're forming a GET request, i.e. ?var=1&var2=2 but you've sent it as a POST request, you need to send the request as a GET request so that the variables are displayed in the url bar as you expect them to be displayed.

Answer 2

This is the full example, it works very well with one parameter, just change the id to that of your page.

function bartag_func( $atts ) { 
    global $wp;
    $view = $wp->query_vars['jp_stn'];
    return $view;
}
add_shortcode( 'bartag', 'bartag_func' );


function cdl_rewrite_rule(){
    add_rewrite_rule(
        'pronosticador/([-a-z]+)/?$',
        'index.php?page_id=52&jp_stn=$matches[1]',
        'top'
    );
}
add_action( 'init', 'cdl_rewrite_rule' );

function cdl_query_vars( $query_vars ){
    $query_vars[] = 'jp_stn';
    return $query_vars;
}
add_filter( 'query_vars', 'cdl_query_vars' );

To achieve pretty URLs with parameters in WP, you can utilize the rewrite rules provided by WordPress along with a custom endpoint or a rewrite rule.

you need to register a custom rewrite rule to handle the pretty URL. Add the following code to your themes functions.php file

function custom_rewrite_rule() {
    add_rewrite_rule('^myparameters/([^/]+)/?', 'index.php?pagename=myparameters&myvar=$matches[1]', 'top');
}
add_action('init', 'custom_rewrite_rule', 10);

function custom_query_vars($query_vars) {
    $query_vars[] = 'myvar';
    return $query_vars;
}
add_filter('query_vars', 'custom_query_vars', 10, 1);

After adding the rewrite rule, you need to flush the rewrite rules for Wp to recognize the new rule. You can do this by visiting the "Settings" > "Permalinks" page in your WP admin area

Update your shortcode function to retrieve the value of myvar from the query variables instead of $_GET

function test_func($atts) {
    $myvar = get_query_var('myvar');
    return $myvar;
}
add_shortcode('test', 'test_func');
