如何在 Wordpress 的简码中使用此 PHP 代码？

Question

How can I use the following code in a WordPress shortcode?

//Variables
$DesdeLetra = "a";
$HastaLetra = "z";
$DesdeNumero = 1;
$HastaNumero = 10000;

$letraAleatoria = chr(rand(ord($DesdeLetra), ord($HastaLetra)));
$numeroAleatorio = rand($DesdeNumero, $HastaNumero);

echo "<strong>La letra aleatoria generada en PHP es:</strong> ".$letraAleatoria."<br/>";
echo "<strong>El número aleatorio generado en PHP es:</strong> ".$numeroAleatorio."<br/>";

Answer 1

Assuming that the code works, you can try this:

add_shortcode( 'yourshortcode', 'so61578297_custom_shortcode' );
function so61578297_custom_shortcode() {

  $DesdeLetra = "a";
  $HastaLetra = "z";
  $DesdeNumero = 1;
  $HastaNumero = 10000;

  $letraAleatoria = chr(rand(ord($DesdeLetra), ord($HastaLetra)));
  $numeroAleatorio = rand($DesdeNumero, $HastaNumero);

  $r = "<strong>La letra aleatoria generada en PHP es:</strong> ".$letraAleatoria."<br/>";
  $r .= "<strong>El número aleatorio generado en PHP es:</strong> ".$numeroAleatorio."<br/>";

  return $r;

}

Past this snippet in your theme's functions.php file, then you can use the shortcode in the WP editor:

[yourshortcode]

As you are generating random letters/numbers, be sure to not have any caching active on that page.

Good luck!
