首先安装插件。
* 核心插件 Contact Form 7

然后，在主题functions.php文件添加短代码功能。
/* WordPress Shortcode Function mf_cf7_RandomStringGenerator() */
/* Required Plugin: Contact Form 7, Contact Form 7 - Dynamic Text Extension */
/* recommended Plugin: Flamingo */
/* Add this function on functions.php theme or on your plugin */
function mf_cf7_RandomStringGenerator() {
$mfstringlength = 8; // Length number generated
$mfcharacter = "012356789abcdefghijklmnopqrstuvwxyz"; // random character
for ($p = 0; $p < $mfstringlength; $p++) {
$string .= $mfcharacter[mt_rand(0,strlen($mfcharacter)-1)];
}
return $string;
}
add_shortcode('MF_CF7_RANDOMSTRINGGENERATOR', 'mf_cf7_RandomStringGenerator');Contact Form 7表单编辑时直接引用即可。
