Controlling Behavior by Setting Constants

Contact Form 7 allows you to control its behavior by setting some constant values.

The typical place to define constants is in the wp-config.php file. You will find that many lines defining constants such as, define('XXX', 'xxx'); exist in the file. You can append new lines after them. Note that your lines must be placed before the last line.

Example (wp-config.php):


define ('WPLANG', '');

define ('WPCF7_LOAD_JS', false); // Added to disable JS loading
define ('WPCF7_LOAD_CSS', false); // Added to disable CSS loading

/* That's all, stop editing! Happy blogging. */

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
	define('ABSPATH', dirname(__FILE__) . '/');

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');

The rest of this post describes a variety of constants.

Constant Description
WPCF7_LOAD_JS When the value of this constant is false (default: true), Contact Form 7 does not load the JavaScript on the front end. When the value of this constant is set as ‘header’, Contact Form 7 loads the JavaScript in the header instead of in the footer (default).
WPCF7_LOAD_CSS When the value of this constant is false (default: true), Contact Form 7 does not load the CSS stylesheet on the front end.
WPCF7_AUTOP When the value of this constant is false (default: true), Contact Form 7 does not apply the ‘autop’ filter to the form content. The ‘autop’ filter replaces double line-breaks with paragraph elements.
WPCF7_USE_PIPE When the value of this constant is false (default: true), Contact Form 7 disables its ‘pipe’ feature, so that pipe character has no special meaning.
WPCF7_ADMIN_READ_CAPABILITY The value of this constant holds the minimum capability required for access to the administration panel. The default value is ‘edit_posts’.
WPCF7_ADMIN_READ_WRITE_CAPABILITY The value of this constant holds the minimum capability required for editing contact forms. The default value is ‘publish_pages’. Obviously WPCF7_ADMIN_READ_WRITE_CAPABILITY should be stricter than WPCF7_ADMIN_READ_CAPABILITY, as you cannot edit contact forms without accessing the administration panel.
WPCF7_CAPTCHA_TMP_DIR When this constant is defined, the value of the constant overrides the setting of directory path of temporary folder for CAPTCHA files.
WPCF7_CAPTCHA_TMP_URL When this constant is defined, the value of the constant overrides the setting of URL of temporary folder for CAPTCHA files.
WPCF7_UPLOADS_TMP_DIR When this constant is defined, the value of the constant overrides the setting of directory path of the temporary folder for uploaded files.
