Weitere Informationen
While wpforms_frontend_output_before only fires for valid non-empty forms, it executes early on in the output rendering process.
In some cases, the action may fire but the form will not display, such as displaying a form confirmation message or triggering the wpforms_frontend_load filter.
An alternate action to consider is wpforms_frontend_output_after, as it functions similarly, except only fires after the form is displayed.
Beispiele
In our example code snippet, you’ll see below, we are going to be checking first to see if the form ID is equal to 5. If it is, we’ll echo out a link to download the digital catalog.
Just remember to change the form ID from 5 to match the specific form ID you’re wanting to run your code on. Removing that check would run for all forms.
/**
* Output something before your form(s).
*
* @link https://wpforms.com/developers/wpforms_frontend_output_before/
*
* @param array $form_data Form data and settings.
* @param object $form Form post type object.

function wpf_dev_frontend_output_before( $form_data, $form ) {
// Optional, you can limit to specific forms. Below, we restrict output to
// form #5.
if ( absint( $form_data[ 'id' ] ) !== 5 ) {
return;
}
// Run code or see the example echo statement below.
