thinkPHP form automatic verification function, thinkphp form verification

Last night our boss asked me to work on the form automatic verification function, and I spent a long time worrying about it and borrowed a lot of knowledge from official websites before I came up with it, eh , anyway, let me share my own results!

thinkphp defines automatic verification functions and regular expressions for us in the Model base class. We only need to establish the $_validate attribute under the model class of the corresponding database table.

1. We find the Model base class and can see protected $_validate = array(); // Automatically verify that it is of array type. Define it in the corresponding data model file below;

2,

public <span>function</span><span> CheckVerify($verify) {

   </span><span>if</span> (md5($verify) != Session::get('verify')) <span>return</span> <span>false</span><span>;
        </span><span>return</span> <span>true</span><span>;
}</span>

//Automatic verification

   protected $_validate =<span> array(
        array(</span>"title", "require", "标题必须！"<span>),
        array(</span>'categoryId', 'require', "类别必须！"<span>),
        array(</span>'content', 'require', "内容必须！"<span>),
        array(</span>'verify', 'require','验证码必须！'<span>),
        array(</span>'verify', 'CheckVerify', '验证码错误！', 0, 'callback'<span>)
    );</span>

3. Format description: array (validation fields, validation rules, error prompts, validation conditions, additional rules, validation time),

4. Parameter explanation:

Verification field: The name of the form field that needs to be verified. This field is not necessarily a database field, but can also be some auxiliary fields of the form, such as confirming passwords and verification codes, etc.
Verification rules: The rules for verification need to be combined with additional rules (required). The official rules included are as follows (you can also add them yourself):

 1 $validate =<span> array(
 </span>2 
 3             'require'=> '/.+/'<span>,
 </span>4 
 5             'email' => '/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/'<span>,
 </span>6 
 7             'url' => '/^http:\/\/[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\?%\-&_~`@[\]\':+!]*([^<>\"\"])*$/'<span>,
 </span>8 
 9             'currency' => '/^\d+(\.\d+)?$/'<span>,
</span>10 
11             'number' => '/^\d+$/'<span>,
</span>12 
13             'zip' => '/^[1-9]\d{5}$/'<span>,
</span>14 
15             'integer' => '/^[-\+]?\d+$/'<span>,
</span>16 
17             'double' => '/^[-\+]?\d+(\.\d+)?$/'<span>,
</span>18 
19             'english' => '/^[A-Za-z]+$/'<span>,
</span>20 
21         );<br /><br />

Prompt information: Definition of prompt information after verification failure (required),
Verification conditions: (optional)
There are three rules for verification conditions:
Model::EXISTS_TO_VAILIDATE or 0 field exists Just verify (default)
Model::MUST_TO_VALIDATE or 1 Must verify
Model::VALUE_TO_VAILIDATE or 2 Verify when the value is not empty
Additional rules:
regex regular verification, indicating the previous verification The rule is a regular expression;
function uses function verification, indicating that the previous verification is a function name;
callback uses method verification, indicating that the verification rule is a method of the Model class;
confirm verifies that in the form Whether two fields are equal, the verification rule is a field name;
equal verifies whether it is equal to a certain value, which is defined by the previous verification rule;
in verifies whether it is within a certain range, defined previously is an array;
unique is used to verify whether it is unique. The system will query the database based on the current value of the field to determine if the same value exists;
At the same time, the system also has built-in some commonly used regular verification rules, which can be used in this section , including: require field must be email;
currency, number. These verification rules can be used directly;

Verification time: (optional)

01.Model:: MODEL_INSERT or 1 to verify when adding data
02.Model:: MODEL_UPDATE or 2 to verify when editing data
03.Model:: MODEL_BOTH or 3 to verify in all cases (default)

5. Official example:

protected $_validate  =<span>  array(   
array(</span>'verify','require','验证码必须！'), <span>//</span><span>默认情况下用正则进行验证   </span>
array(name,'','帐号名称已经存在！',0,&rsquo;unique&rsquo;,1), <span>//</span><span> 在新增的时候验证name字段是否唯一   </span>
array('value',array(1,2,3),'值的范围不正确！',2,&rsquo;<span>in</span>&rsquo;), <span>//</span><span> 当值不为空的时候判断是否在一个范围内   </span>
array('repassword','password','确认密码不正确',0,&rsquo;confirm&rsquo;), <span>//</span><span> 验证确认密码是否和密码一致   </span>
array('password','checkPwd','密码格式不正确',0,&rsquo;<span>function</span>&rsquo;)<span>//</span><span> 自定义函数验证密码格式  </span>
);

I don’t know if it meets the requirements of our boss, but it’s still coming out. It’s so hard! ! I spent the whole night looking for codes, cases, and comfort! !
