[Plugin: Contact Form 7] How to pull mail recipient from Post’s cusom field?

Hi Valdi

Could you share any more information on how you solved this? I’ve been looking for an answer to this for some time now.

Thanks.

Here is a very easy way of doing this:

Just follow the instructions at the top of the script.

<?php
/**
** A base module for [hidden customfield]
**
**--Instructions--
** Put this script as a file (hidden_custom.php) into the plugins/contact-form-7/modules/ folder.
** "Hidden Custom Field" should now be an option in the "Generate Tag" dropdown of your contact form.
** Type the name of your custom field in the "The Custom Field name goes here" field.
** Put the 2 generated into the form and email as indicated.
**

// Shortcode handler

wpcf7_add_shortcode( hidden, 'wpcf7_hidden_shortcode_handler', true );

function wpcf7_hidden_shortcode_handler( $tag ) {
	if ( ! is_array( $tag ) )
		return '';

	$name = $tag['name'];

	$options = (array) $tag['options'];
	$values = (array) $tag['values'];

	$atts = '';
	$id_att = '';

	$class_att .= ' wpcf7-hidden';

	foreach ( $options as $option ) {
		if ( preg_match( '%^id:([-0-9a-zA-Z_]+)$%', $option, $matches ) ) {
			$id_att = $matches[1];
		}
	}

	if ( $id_att )
		$atts .= ' id="' . trim( $id_att ) . '"';

	global $wp_query;

	$postid = $wp_query->post->ID;

	$theCustomValue = get_post_meta($postid, $name , true);

	$value = $theCustomValue;

	$html = '<input name="'.$name.'" type="hidden" value="' . esc_attr( $value ) . '"' . $atts . ' />';

	return $html;
}

// Tag generator

add_action( 'admin_init', 'wpcf7_add_tag_generator_hidden', 50 );

function wpcf7_add_tag_generator_hidden() {
	wpcf7_add_tag_generator( 'hidden', __( 'Hidden Custom Field', 'wpcf7' ),
		'wpcf7-tg-pane-hidden', 'wpcf7_tg_pane_hidden' );
}
