让WordPress登录页的密码框显示最后一个输入的字符
在通常情况下,网页的设计者们会将密码输入框中的所有字符隐藏成黑点,以防止有人在背后偷窥输入的密码,如:
这种密码输入模式虽然减少了被偷窥的危险,但是给我们的密码输入带来了很多麻烦,因为我们不知道到底输入了什么字符,所以经常导致输错密码的情况,浪费了很多时间。
可能你也已经注意到,现在智能手机的很多应用中,使用了这样一种密码框处理方式:对用户在密码框中输入的最后一个字符,会先让它显示2-3秒钟,然后再隐藏,这样可以让用户知道刚刚输入了什么字符,减少了输错的可能性,同时兼具防偷窥功能。如:
今天,我将给大家介绍,在WordPress中如何实现这个的功能,步骤非常简单。
1、添加js
点此下载 需要用到的js,将此js文件放到当前使用主题的根目录下。
2、添加php代码
用文本编辑器打开当前主题的functions.php,添加以下php代码:
function ludou_dPassword() { wp_enqueue_script( 'dPassword', get_template_directory_uri() . '/jQuery.dPassword.js', array(), '1.0', true ); } add_action( 'login_enqueue_scripts', 'ludou_dPassword' );
好了,这个功能就添加成功了,就这么简单。
补充说明
1、如果你要将js文件放在当前主题的js目录,那你需要将php代码第2行中的 /jQuery.dPassword.js 改成 /js/jQuery.dPassword.js
2、此功能在输入密码时,只能在最后输入或删除字符,已经被隐藏成黑点的密码中间不能添加或删除字符。
让WordPress登录框显示/隐藏输入的密码
这可以让用户知道刚刚输入了什么字符,减少了输错密码的可能性,同时兼具防偷窥功能。
现在,我们还有另外一种选择,直接让用户自行根据需要选择是全部隐藏输入的密码,还是全部显示输入的密码。在全部显示密码框的内容时,用户输错的可能性就大大降低,这也是微软推荐的一种密码框处理方式。效果如下:
全部隐藏密码,点击密码框右边的眼睛图标可以显示密码
全部显示密码,点击密码框右边的锁头图标可以隐藏密码
1、添加js
点此下载 需要用到的js,将此js文件放到当前使用主题的根目录下。
2、添加php代码
function ludou_prevue() { wp_enqueue_script("jquery"); wp_enqueue_script( 'prevue', get_template_directory_uri() . '/jquery.prevue.min.js', array(), '1.0', true ); ?> <style type="text/css"> .prevue-icon-eye:before { content: "\f177"; } .prevue-icon-eye-off:before { content: "\f160"; } </style> <?php } add_action( 'login_enqueue_scripts', 'ludou_prevue' ); ?>
好了,大功造成!
补充说明
1、如果你要将js文件放在当前主题的js目录,那你需要将php代码第3行中的 /jquery.prevue.min.js 改成 /js/jquery.prevue.min.js
2、此功能需要1.9.0以上版本的jQuery支持。

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
