Hook Examples

Set custom value in repeating field

Use the code below to set a custom value in a repeating field. Replace 508 with the ID of the repeating section field. Replace 11700 with the ID of the field that you want to modify.

Remove special characters

It checks to ensure that no special characters are in the values inputted by the form user.

It was developed to detect and prevent special characters being added to the database.

It was needed to support the Comprehensive Google Map plugin, as that plugin does not like having non-alpha-numeric characters in any field it is displaying. The plugin is here: http://wordpress.org/plugins/comprehensive-google-map-plugin/

If you have dev / test / staging / production instances of WP, be sure to use the production form IDs in your production functions.php.

See example >
Only allow the action once

There may be times when an email or another form action is set to trigger on update or after successful payment, but you really only want it to trigger once. This example uses two hooks: one to set when an action has been triggered, and one to stop it the next time.
