I am sorry, I communicate slightly English.
Methods to create a customized WordPress web page with my plugin? I would love see solely a textual content.
Instance, what I would love:
~/wp-content/plugins/custompageforwp/custompageforwp.php
<?php
/**
* Plugin Title: CUSTOM PAGE FOR WP
*/
// What I would love:
if( $uri == 'custompageforwp' ) { // https://mywebsite.com/custompageforwp or custompageforwp.php
print '<html><physique>Hiya world</physique></html>';
} else {}
?>
Thanks.
