WordPress一般默认用户不能填写密码，都是系统自动给用户生成一个密码，并发送到用户邮箱，对于用户来讲是不习惯的，今天分享WordPress实现自定义密码来优化用户注册体验，让用户自己设置账户密码，其实很简单只需要在主题的 function.php 加上以下代码：
<?php
add_action( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’register_form\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’v7v3_show_register\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ );
function v7v3_show_register(){
?>
<p>
<label for=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>密码：<br/>
<input id=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” class=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”input\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” type=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” tabindex=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”30\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” size=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”25\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” value=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” name=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” />
</label>
</p>
<p>
<label for=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”repeat_password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>确认密码<br/>
<input id=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”repeat_password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” class=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”input\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” type=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” tabindex=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”40\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” size=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”25\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” value=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” name=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”repeat_password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” />
</label>
</p>
<p>
<label for=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”are_you_human\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>挖掘机技术哪家强？（蓝翔）<br/>
<input id=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”are_you_human\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” class=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”input\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” type=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”text\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” tabindex=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”40\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” size=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”25\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” value=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” name=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”are_you_human\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” />
</label>
</p>
<?php
}
add_action( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’register_post\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ts_check_extra_register_fields\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, 10, 3 );
function ts_check_extra_register_fields($login, $email, $errors) {
if ( $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] !== $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’repeat_password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] ) {
$errors->add( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’passwords_not_matched\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”<strong>ERROR</strong>: 两次密码不一致\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” );
}
if ( strlen( $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] ) < 8 ) {
$errors->add( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’password_too_short\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”<strong>ERROR</strong>: 密码长度小于8位！\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” );
}
if ( $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’are_you_human\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] !== \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’蓝翔\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ ) {
$errors->add( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’not_human\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”<strong>ERROR</strong>: 回答错误，请重新填写注册信息！\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” );
}
}
为了保证不被注册机骚扰此代码中还自带了一个验证问题字段，防止注册机批量注册垃圾用户。虽然让用户可以自己填写密码，但是有些用户更加喜欢让系统为他生成密码，为了给这些用户提供方便，我们可以判断下当前用户注册时是否填了密码，如果没填再让系统生成一个，代码如下：
add_action( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’user_register\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ztmao_register_extra_pass\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, 100 );
function ztmao_register_extra_pass( $user_id, $password=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”, $meta=array() ){
$userdata = array();
$userdata[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ID\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] = $user_id;
if( $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] ){
$userdata[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’user_pass\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] = $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’password\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’];
}
wp_update_user($userdata);
}
/*如果强制用户输入密码，则可将此段代码的注释去除
add_action(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’admin_init\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’remove_default_password_nag\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’);
function remove_default_password_nag() {
global $user_ID;
delete_user_setting(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’default_password_nag\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, $user_ID);
update_user_option($user_ID, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’default_password_nag\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, false, true);
}
*/
当然为了给用户更好的体验，我们可以在注册框下方加个提示，代码如下：
add_filter( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’gettext\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’v7v3_edit_text\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ );
function ztmao_edit_text( $text ) {
if ( $text == \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’A password will be e-mailed to you.\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ ) {
$text = \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’如果您不填写密码，系统将为您生成一个密码， 并发送至您的邮箱。\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
}
return $text;
}
