How to implement verification Code success verification function? Submit a verification code? This article is for everyone to answer.

Tidy up what you have mastered today, or else I'll forget it:

Today in a corporate website, there is a function of the online message, the final submission of the need to enter a verification code. Under

Of course, the connection is not my backstage.

OK, here we go, first I need to show the verification code, the front page:

<p class= "Message-con clearfix" > <p class= "mcon-left pic pull-left" ></p> <p class=" Mcon-right pull-right "> <form method=" POST " Action= "{: U (' Validate ')}" Name= ' Valiate ' > <label><span> name </span><input type= "text" Name= " Xingming "class=" Mname "value=" "/><em>*</em></label> <label><span> Contact Phone </span ><input type= "Text" name= "tel" class= "Mtel"/><em>*</em></label> <label><span > Contact Address </span><input type= "text" name= "Dizhi" class= "Madd"/></label> <label><span> e-mail address </span><input type= "text" name= "Youxiang" class= "Memail"/></label> <label><span> Message content </span><textarea name= "content" class= "Mcontent" ></textarea><em>*</em></ label> <label class= "Mcodela" ><input type= "text" name= "code" class= "Mcode"/>  <a href=" # "rel=" external nofollow "> can't see clearly? Change one </a><em>*</em></label> <label><input type= "Submit" class= "Msub" name= "TJ" value = "Online submission"/></label> </form> </p> </p> </p>

Good click event, name, Submit button has been changed, go, go to controller;

Come to the controller here, do one thing first, introduce model bar:

Use Otcms\model;

There's no model class to write for yourself:

<?phpnamespace otcms\model;use think\model;class Usermodel extends model{protected $_validate = Array (  ' Xingming ', ' require ', ' the name is not empty! '),  Array (' tel ', ' require ', ' mobile phone number is not available! '),  array (' Dizhi ', ' require ', ' Address not empty! '),  array (' Youxiang ', ' Require ', ' Mailbox not empty! '),  array (' content ', ' require ', ' contents are not empty! '), );}

To set the verification code:

Show:

Public Function Verify () {  $config = array (   ' fontSize ' = + 30,//captcha font size   ' length ' =  4,/  / Verification code number  );  $verify = New\think\verify ($config);  $verify->entry (); }

Below to write the conditions:

Public function Validate () {  $date [' xingming '] = I (' post.xingming ');  $date [' tel '] = I (' Post.tel ');  $date [' dizhi '] = I (' Post.izhi ');  $date [' youxiang '] = I (' Post.youxiang ');  $date [' content '] = I (' post.content ');  $yzm = I (' Post.code ');  $fkyz = D ("Liuyan");  if (! $fkyz->create ()) {   //If the creation fails to indicate that validation did not pass the output error message   exit ($fkyz->geterror ());  } else{     //validation can be done by other data operations   $verify = new \think\verify ();   $yzmyz = $verify->check ($YZM);   if (! $yzmyz) {    $this->error (' captcha error ');   }   else{    $validate = M ("Liuyan");    $validate->add ($date);    $this->success (' Add success ');   }  } }
