thinkPHP实现表单自动验证,thinkphp实现表单
昨天晚上我们老大叫我弄表单自动验证功能,愁了半天借鉴了好多官网的知识,才出来,诶,总之分享一下我自己的成果吧!
thinkphp 在Model基类为我们定义了自动验证的函数和正则表达式,我们只需要在对应的数据库表的模型类下建立$_validate属性就可以了。
1、我们找到Model基类,可以看到 protected $_validate = array(); // 自动验证定,它是数组类型的,下面在对应数据模型文件定义它;
2、
复制代码 代码如下:
public function CheckVerify($verify) {
if (md5($verify) != Session::get('verify')) return false;
return true;
}
//自动验证
复制代码 代码如下:
protected $_validate = array(
array("title", "require", "标题必须!"),
array('categoryId', 'require', "类别必须!"),
array('content', 'require', "内容必须!"),
array('verify', 'require','验证码必须!'),
array('verify', 'CheckVerify', '验证码错误!', 0, 'callback')
);
3、格式说明:array(验证字段,验证规则,错误提示,验证条件,附加规则,验证时间),
4、参数解释:
验证字段:需要验证的表单字段名称,这个字段不一定是数据库字段,也可以是表单的一些辅助字段,例如确认密码和验证码等等。
验证规则: 要进行验证的规则,需要结合附加规则(必须),官方已经包含的规则如下(自己同时也可以加):
复制代码 代码如下:
$validate = array(
'require'=> '/.+/',
'email' => '/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/',
'url' => '/^http:\/\/[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\?%\-&_~`@[\]\':+!]*([^\"\"])*$/',
'currency' => '/^\d+(\.\d+)?$/',
'number' => '/^\d+$/',
'zip' => '/^[1-9]\d{5}$/',
'integer' => '/^[-\+]?\d+$/',
'double' => '/^[-\+]?\d+(\.\d+)?$/',
'english' => '/^[A-Za-z]+$/',
);
提示信息: 用于验证失败后的提示信息定义(必须)、
验证条件:(可选)
验证条件的规则有三条:
Model::EXISTS_TO_VAILIDATE 或者0 存在字段就验证 (默认)
Model::MUST_TO_VALIDATE 或者1 必须验证
Model::VALUE_TO_VAILIDATE或者2 值不为空的时候验证
附加规则:
regex 正则验证,说明前面的那个验证规则是一个正则表达式;
function 使用函数验证,说明前面的那个验证是个函数名;
callback 使用方法验证,说明验证规则是一个Model类的方法;
confirm 验证表单中的两个字段是否相等,验证规则是一个字段名;
equal 验证是否等于某个值,这个值是有前面的验证规则定义的;
in 验证是否在某个范围之内,前面定义的是一个数组;
unique 验证是否唯一,系统会根据字段目前的值查询数据库来判断时候存在相同的值;
同时,系统还内置了一些常用的正则验证规则,可以这节使用,包括:require字段必须,email 邮箱;
currency 货币,number 数字,这些验证规则可以直接使用;
验证时间:(可选)
01.Model:: MODEL_INSERT 或者1新增数据时候验证
02.Model:: MODEL_UPDATE 或者2编辑数据时候验证
03.Model:: MODEL_BOTH 或者3 全部情况下验证(默认)
5、官方示例:
复制代码 代码如下:
protected $_validate = array(
array('verify','require','验证码必须!'), //默认情况下用正则进行验证
array(name,'','帐号名称已经存在!',0,'unique',1), // 在新增的时候验证name字段是否唯一
array('value',array(1,2,3),'值的范围不正确!',2,'in'), // 当值不为空的时候判断是否在一个范围内
array('repassword','password','确认密码不正确',0,'confirm'), // 验证确认密码是否和密码一致
array('password','checkPwd','密码格式不正确',0,'function')// 自定义函数验证密码格式
);
也不知道符合我们老大的要求不,总之还算是出来了,好辛苦啊!! 大晚上的找代码,找案例,求安慰!!

Performance comparison of Laravel and ThinkPHP frameworks: ThinkPHP generally performs better than Laravel, focusing on optimization and caching. Laravel performs well, but for complex applications, ThinkPHP may be a better fit.

"Development Suggestions: How to Use the ThinkPHP Framework to Implement Asynchronous Tasks" With the rapid development of Internet technology, Web applications have increasingly higher requirements for handling a large number of concurrent requests and complex business logic. In order to improve system performance and user experience, developers often consider using asynchronous tasks to perform some time-consuming operations, such as sending emails, processing file uploads, generating reports, etc. In the field of PHP, the ThinkPHP framework, as a popular development framework, provides some convenient ways to implement asynchronous tasks.

ThinkPHP is a high-performance PHP framework with advantages such as caching mechanism, code optimization, parallel processing and database optimization. Official performance tests show that it can handle more than 10,000 requests per second and is widely used in large-scale websites and enterprise systems such as JD.com and Ctrip in actual applications.
