caldera_forms_render_get_field

This filter can be used to modify the configuration of a field before it is rendered. It is also used during form submission. Keep in mind there are two dynamically named filters for modifying fields as well.

One use for this filter is to change the default value of a field:

	<?php
	add_filter( 'caldera_forms_render_get_field', function( $field ) {
	if( 'fld123456' == $field[ 'ID' ] ){
	$field[ 'config' ][ 'default' ] = esc_url_raw( caldera_forms_get_current_url() );
	}
	return $field;
	});

One excellent use for it is to change the options of a select field. In this example, a fields options are set using posts in a specific custom post type, with a specific value of a meta field:

	<?php
	add_filter( 'caldera_forms_render_get_field', function( $field ) {
	if ( 'stores_in_pa' == $field[ 'slug' ] ) {
	$stores = get_posts( array( 'post_type' => 'stores', 'meta_key' => 'state', 'meta_value' => 'PA' ) );
	if ( ! empty( $stores ) ) {
	foreach( $stores as $store ) {
	$field[ 'config' ][ 'option' ][ $store->ID ] = array(
	'value' => $store->ID,
	'label' => $store->post_title
	);
	}
	}
	}
	return $field;
	});

Here is an example of how to reset the default value for a select field based on a custom field for the current user:

	<?php
	add_filter( 'caldera_forms_render_get_field', function( $field, $form ){
	if( 'dropdown' == $field[ 'type'] && ! empty( $field[ 'config' ][ 'option' ] ) ){
	//@TODO Change field name to the right user custom field
	$meta = get_user_meta( get_current_user_id(), 'field_name', true );
	if ( ! empty( $meta ) ) {
	foreach ( $field[ 'config' ][ 'option' ] as $option => $args ) {
	if ( $meta == $args[ 'value' ] ) {
	$field[ 'config' ][ 'default' ] = $option;
	}
	}
	}
	}
	return $field;
	}, 10, 2);

Make A Field Not Required

You can use the “required” index of the array exposed by this filter to control if a field is required or not. This is a good way to avoid situations where a processor makes a field required.

	<?php
	/**
	* Set a specific Caldera Forms field to NOT be required
	*/
	add_filter( 'caldera_forms_render_get_field', function( $field ){
	//IMPORTANT: Change this to your field's ID
	if( 'fld1234' === $field[ 'ID' ] ){
	$field[ 'required' ] = 0;
	}
	return $field;
	});
