WordPress implements the frontend registration function

1. Add a registry ticket

1. First create a php file under the Directory of the current topic, name it reg-page.php, and then copy all the code in page. php to the reg-page.php;

2. Delete all comments starting with the reg-page.php, I .e./* and */, and all contents between them;

3. Search for the_content. You can find similar code: <? Php the_content ();?>, Replace this code with code 1 (note that using UTF-8 encoding to save as replacing the original reg-page.php)

If you cannot find the_content in the reg-page.php, you can find: get_template_part, you can find similar code: <? Php get_template_part ('content', 'page');?>, Replace all the code in the content-page.php with this code. Replace it with the following code <? Php the_content ();?>

<? Php the_content ();?>
<? Php if (! Empty ($ error )){
Echo '<p class = "ludou-error">'. $ error .'';
}

<? Php

If (! Empty ($ _ POST ['MK _ reg ']) {
$ Error = '';
$ Sanitized_user_login = sanitize_user ($ _ POST ['User _ login']);
$ User_email = apply_filters ('User _ registration_email ', $ _ POST ['User _ email']);
 
// Check the username

  }

If (! $ User_id ){
$ Error. = sprintf ('<strong> error </strong>: your registration request cannot be completed... contact <a href = \ "mailto: % s \"> administrator </a>! <Br/> ', get_option ('admin _ email '));
    }
Else if (! Is_user_logged_in ()){
$ User = get_userdatabylogin ($ sanitized_user_login );
$ User_id = $ user-> ID;
 
// Automatic logon
Wp_set_current_user ($ user_id, $ user_login );
Wp_set_auth_cookie ($ user_id );
Do_action ('WP _ login', $ user_login );
    }
  }
}
If (! Is_user_logged_in () {?>
<Form name = "registerform" method = "post" action = "<? Php echo $ _ SERVER ["REQUEST_URI"];?> "Class =" mk-reg ">
<P>
<Label for = "user_login"> user name <br/>
<Input type = "text" name = "user_login" tabindex = "1" id = "user_login" class = "input" value = "<? Php if (! Empty ($ sanitized_user_login) echo $ sanitized_user_login ;? /> "/>

</P>
</Form>
<? Php} else {
Echo '<p class = "mk-error"> You have registered and logged on! ';
}?>
2. Add Form processing code

At the beginning of the reg-page.php, place the first <? Php changed to code 2 (note the use of UTF-8 encoding to save ):

Finally, go to the WordPress management background-page-create page, with the title registration (you can name it yourself), and enter the registration instructions in the content. On the right side, select a template and select "register at the front end. This page is the front-end registration page. Place the link on this page to any location of the website for users to click registration.

Code Supplement

1. If the registration is successful, the user will log on automatically. If you do not need the automatic function, you can delete line 49-55 of code and replace it:

// After successful registration, jump to other pages on the site and modify the URL.
Wp_safe_redirect ('http: // www.111cn.net /');
 
 
2nd, if you want to optimize the registration form, you can add the following code to the topic's style.css:
 
<Pre lang = "php" line = "1">
P. mk-error {
Margin: 16px 0;
Padding: 12px;
Background-color: # ffebe8;
Border: 1px solid # c00;
Font-size: 12px;
Line-height: 1.4em;
}
. Mk-reg label {
Color: #777;
Font-size: 14px;
Cursor: pointer;
}
. Mk-reg. input {
Margin: 0;
Color: #555;
Font-size: 24px;
Padding: 3px;
Border: 1px solid # e5e5e5;
Background: # fbfbfb;
}
