WordPress supports foreground login

1. Add a logon form

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

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

3. Search: the_content. Similar code can be found. <? Php the_content ();?>, Replace it with code 1 (note that it is saved using UTF-8 encoding)

If you cannot find the_content in the page-login.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 <? Php the_content ();?>

<? Php the_content ();?>
<? Php if (! Empty ($ error )){
Echo '<p class = "mk-error">'. $ error .'';
}
If (! Is_user_logged_in () {?>
<Form name = "loginform" method = "post" action = "<? Php echo $ _ SERVER ["REQUEST_URI"];?> "Class =" mk-login ">
<P>
<Label for = "log"> user name <br/>
<Input type = "text" name = "log" id = "log" class = "input" value = "<? Php if (! Empty ($ user_name) echo $ user_name ;? /> "Size =" 20 "/>
</Label>
</P>
<P>
<Label for = "pwd"> password (at least 6 digits) <br/>
<Input id = "pwd" class = "input" type = "password" size = "25" value = "" name = "pwd"/>
</Label>
</P>
 
<P class = "forgetmenot">
<Label for = "rememberme">
<Input name = "rememberme" type = "checkbox" id = "rememberme" value = "1" <? Php checked ($ rememberme );? />
Remember Me
</Label>
</P>
 
<P class = "submit">
<Input type = "hidden" name = "redirect_to" value = "<? Php if (isset ($ _ GET ['R']) echo $ _ GET ['R'];? /> "/>
<Input type = "hidden" name = "mk_token" value = "<? Php echo $ token ;? /> "/>
<Button class = "button-primary button-large" type = "submit"> Log on </button>
</P>
</Form>
<? Php} else {
Echo '<p class = "mk-error"> you are logged on! (<A href = "'. wp_logout_url ().'" title = "logout"> logout? </A> )';
}?>

2. Add Form processing code

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

<? Php
/**
* Template Name: foreground logon
* Author: MK
* Blog: http://www.111cn.net/
 * 
* May April 6, 2015:
* First version
 * 
* May April 6, 2015:
* Prevent repeated data submission from refreshing the page
*/
 
If (! Isset ($ _ SESSION ))
Session_start ();
 
If (isset ($ _ POST ['MK _ token']) & ($ _ POST ['MK _ token'] = $ _ SESSION ['MK _ token']) {
$ Error = '';
$ Secure_cookie = false;
$ User_name = sanitize_user ($ _ POST ['log']);
$ User_password = $ _ POST ['pwd'];
If (empty ($ user_name) |! Validate_username ($ user_name )){
$ Error. = '<strong> error: enter a valid user name. <Br/> ';
$ User_name = '';
  }
 
If (empty ($ user_password )){
$ Error. = '<strong> error </strong>: enter the password. <Br/> ';
  }
 
If ($ error = ''){
// If the user wants ssl but the session is not ssl, force a secure cookie.
If (! Empty ($ user_name )&&! Force_ssl_admin ()){
If ($ user = get_user_by ('login', $ user_name )){
If (get_user_option ('use _ ssl ', $ user-> ID )){
$ Secure_cookie = true;
Force_ssl_admin (true );
        }
      }
    }
 
If (isset ($ _ GET ['R']) {
$ Redirect_to = $ _ GET ['R'];
// Redirect to https if user wants ssl
If ($ secure_cookie & false! = Strpos ($ redirect_to, 'WP-admin '))
$ Redirect_to = preg_replace ('| ^ http: // |', 'https: // ', $ redirect_to );
    }
Else {
$ Redirect_to = admin_url ();
    }
 
If (! $ Secure_cookie & is_ssl () & force_ssl_login ()&&! Force_ssl_admin () & (0! = Strpos ($ redirect_to, 'https') & (0 = strpos ($ redirect_to, 'http ')))
$ Secure_cookie = false;
 
$ Creds = array ();
$ Creds ['User _ login'] = $ user_name;
$ Creds ['User _ password'] = $ user_password;
$ Creds ['member'] =! Empty ($ _ POST ['memberme']);
$ User = wp_signon ($ creds, $ secure_cookie );
If (is_wp_error ($ user )){
$ Error. = $ user-> get_error_message ();
    }
Else {
Unset ($ _ SESSION ['MK _ token']);
Wp_safe_redirect ($ redirect_to );
    }
  }
 
Unset ($ _ SESSION ['MK _ token']);
}
 
$ Rememberme =! Empty ($ _ POST ['memberme']);
 
$ Token = md5 (uniqid (rand (), true ));
$ _ SESSION ['MK _ token'] = $ token;
 
 
 
Finally, go to the WordPress management background-page-create page, with the title "login" (you can name it yourself), enter the logon instructions in the content, select a template on the right, and select "log on to the foreground. This page is the front-end login page.
 
Code Supplement
 
1. If you want to jump to the specified page after logging on, you can add the get parameter "r" after the logon link. The value is the link to jump. For example, if the logon page address is login? R = http://www.mk.org/wp-admin/edit.php
 
2nd, if you want to optimize your table list, 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-login label {
Color: #777;
Font-size: 14px;
Cursor: pointer;
}
. Mk-login. input {
Margin: 0;
Color: #555;
Font-size: 24px;
Padding: 3px;
Border: 1px solid # e5e5e5;
Background: # fbfbfb;
}
