php 列表页判断是否收藏

Jun 20, 2016 pm 12:45 PM

在php文件里

//$list 是个数组 包含每条信息的数据,然后写入以下代码;	foreach($list as $value){		$id=intval($value['id']);//list里面的信息ID		$uid=intval($['uid']);//当前登录用户的ID		$str = //查询数据库where likeid='$id' and uid='$uid';//有没有用户ID和当前信息ID                          //查询条件就是这样,具体代码就不写了 (⊙﹏⊙)b		$like = mysql_num_rows($str);	//判断出来的结果 $like大于0 表示已收藏	}//以上结果 输出 $like 能显示出 每条信息当前用户收藏情况是1还是0//代码没有错误
Copy after login

在html文件里
{loop $list $a}$a[id] - $a[title] -........{/loop}
Copy after login


问题是在html 文件里怎么判断啊?也就是说 把$like和列表的ID关联起来
//在html里面的 $list 写下如下代码 不成功
{loop $list $a}{if $like>0}已收藏{else}未收藏{/if}$a[id] - $a[title] -........{/loop}
Copy after login

代码3 中的 $like 是哪里来的?
既然是表示是否收藏,为何不是 $a[like]

问题就是代码3的$like的值 不等于代码1的值啊

代码3 中的 $like 是哪里来的?

列表list中 并不包含 like字段。

$like 是在php文件中判断的结果。

我就是想把php中的$like能引用到html的list当中

看不出 $like 是从哪里来的,而且是个单值
如果是代码1中查询出来的那个,也应该放进 $list 中去吧?
对于每个 id 和 uid 对而言,$like 都是不一样的

$like 是在哪里赋值的?

$like 是在哪里赋值的?



代码1 是php文件判断$list列表中 每个ID是否在此用户的收藏列表里;
代码2 是html模板页面,list 列表循环输出;

请无视代码3  那是错误的。。。

我就想在html页面 把当前的信息ID和代码1的$value['id'] 关联和判断

比如 代码1 输出是:
$value['id'] : 1 2 3 4 5
           $like:  0 0 0 1 0  //和 $value['id']是对应关系,代表 除了ID4 其他的都没收藏 
那么 我想在html 页面 判断下ID为 1 2 3 4 5 的$like 是多少 怎么做? 当然HTML页面是调用的php文件中的$list

或者大家有更高的代码 那么也可以。 辛苦了 各位

$like 是在哪里赋值的?



好像关键问题就是没有赋值啊 好像

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
