php获取html 文本框的值 两个文本框,出问题了

Jun 23, 2016 pm 02:03 PM

下面是我做的一个日历,输入查询的界面:
==================================================
//以下为程序


查询日历


 

  
   
     
     
     
   
   
     
      
   
  
输入要查询的年份(1900年之后):
输入要查询的月份:

  


  
  
  


 




====================================================================================
我还定义了另一个php文件来获取 year 和 month  但是运行出来它把month的值覆盖到了year上,不过不给month赋值,相当于我只定义了name="year" 的文本框,而且取值部分变成了name="month"文本框的输入。当我把month文本框的 type 改成password 结果可以运行。不过输入的时候月份成了星星...所以问下,是什么问题?

想帮你,不过看不懂你说的意思,绕口了

不知道你遇到了什么问题?
print_r($_POST); 看看

想帮你,不过看不懂你说的意思,绕口了
就是比如说我输入了 年:2004    月:2
然后单击查询,然后编辑输出 得到的数字,代码是这样的:
====================================
$year=$_post["year"];
$month=$_post{"month"];
echo $year;
echo $month;
====================================
最后输出出来的内容:
=======
2
=======
就没了,然后我改一下,只输出$month,即把“echo $year;"删除,结果输出的内容:
========

========
什么都没有,然后我再改一下,只输出$year,即把“echo $month;”删除,加上“ echo $year"
结果输出的内容:
==========
2
==========
说明一个问题就是,程序执行的时候就直接把以year命名的文本框的内容没有赋值给$year,直接忽略了,
然后把以month命名的文本款的内容赋值给$year;还有一种情况就是,程序执行的时候先把以year命名的文本框的内容赋值给$year,然后又把以month命名的文本款的内容赋值给$year,而本来的$month没有赋值。

不知道你遇到了什么问题?
print_r($_POST); 看看
我试过了,详细问题在4楼我给解释了下,希望我写的还算清楚...
只要我把以month命名的文本框的格式改成password,就可以正常运行...
说明两个text 格式的文本框发生了冲突...

搞错了...是三楼~

echo $_POST['year'].'=='.$_POST['month'];
Copy after login

我代码运行了一下,输出来的东西没看来有什么问题,年和月都可以显示啊

加个id试试?


另,
建议改为

$year=$_POST["year"];
$month=$_POST["month"];  //$_POST 大写

$year=$_ POST["year"];
$month=$_ POST {"month"];
echo $year;
echo $month;

加个id试试?

建议改为
嗯,加ID就对了,谢谢啦~

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.
