Share the post "Creating a Shortcode to generate a Random ID"
With this tutorial, we will help you create a new shortcode that will allow you to generate a random ID; like in a Formidable Form hidden field for example.
In our example below, we want to hide a field that can generate a random ID in a form.
First of all, we need to use the mt_rand() PHP function which will return a custom ID. We add an argument that will fetch a number between 1000 and 9999.
Then we give it a custom entity like in our WPU example –
Our custom shortcode - random ID
// Add Shortcode
function wpu_number_entreprise_shortcode() {
$numberplugin = mt_rand(1000, 9999);
return 'wpu-' . $numberplugin;
}
add_shortcode( 'idrand', 'wpu_number_entreprise_shortcode' );So we could obtain something like: wpu-3874
You’re also free to change any arguments within the mt_rand function.
Shortcode : [idrand]
