一段显示全部分类的php代码 想改成显示特定的分类 求帮改下 谢了
add_filter( 'get_terms', 'get_subcategory_terms', 10, 3 );
function get_subcategory_terms( $terms, $taxonomies, $args ) {
$new_terms = array();
if ( in_array( 'product_cat', $taxonomies ) && ! is_admin() && is_shop() ) {
foreach ( $terms as $key => $term ) {
$new_terms[] = $term;
}
$terms = $new_terms;
}
return $terms;
}
这段是现在的代码 我数据库里有一个表有一个字段是term_id 我已经把需要显示的分类的term_id存在了$duqu里面 我想问下 怎么把这个变量插到上面的代码里面可以只显示那些被选出来的term_id的分类呢 谢谢了
回复讨论(解决方案)
你给的代码根本找不到term_id与$duqu,怎么帮你改
一般想达到你的要求,传一个判断就可以了!

不好意思啊 有点忙 才回来看帖子
是这样的 那段代码是程序里自带的 我不太懂 后来那些term_id什么的 是我从数据库表里面自己导出来的 所以变量的名称设的可能不一样
我研究了一下 找到了一个解决方法 但是有一个地方弄不好麻烦你看下会不会 谢了
if ( ! in_array( $term->slug, array( ) ) ){
$new_terms[] = $term;
}
我用了这段程序实现让一部分分类不显示 比如说我不想显示slug值为A的分类 就写成array('A')就可以
但是我想不显示的有很多
$shaixuankuwp_terms=mysql_query("SELECT * FROM `wp_terms` where term_id='".$duqu_term_id."'");
这段我筛选出了表里所有我想不显示的行
while ($duqushujukuwp_terms=mysql_fetch_array($shaixuankuwp_terms)){ $duqu_slug=$duqushujukuwp_terms[slug]; }
这段我一行一行读出了分类的slug
但是我不知道该怎么把$duqu_slug 这个全部放到上面的array()里面 貌似array()里面不能放数组 只能一条条放
码放帮忙看看怎么改啦 谢谢啦
while ($duqushujukuwp_terms=mysql_fetch_array($shaixuankuwp_terms)){ $duqu_slug[]=$duqushujukuwp_terms[slug]; }
$duqu_slug就是你不想显示的行的数组。
while ($duqushujukuwp_terms=mysql_fetch_array($shaixuankuwp_terms)){ $duqu_slug[]=$duqushujukuwp_terms[slug]; }
$duqu_slug就是你不想显示的行的数组。
谢谢啦 虽然已经解决了

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
