兩種驗證碼驗證實現,一種直接在form表單提交按鈕實現驗證,一種使用ajax傳遞參數實現驗證:
1、直接在form表單提交按鈕實現驗證,在控制器VerifyController.class.php中寫入如下代碼:
namespace Home\Controller;use Think\Controller;class VerifyController extends Controller {public function index() {$this->display();}public function checkLogin() {$verify=new \Think\Verify();$code=I('post.verify');//表單驗證碼if($verify->check($code)){$this->success('驗證碼正確');}else{$this->error('驗證碼錯誤');}}public function verify(){// 執行個體化Verify對象$verify = new \Think\Verify();// 配置驗證碼參數$verify->fontSize = 14; // 驗證碼字型大小$verify->length = 4; // 驗證碼位元$verify->imageH = 34; // 驗證碼高度$verify->useImgBg = true; // 開啟驗證碼背景$verify->useNoise = false; // 關閉驗證碼幹擾雜點$verify->entry();}}
在視圖Verify/index.html中的代碼如下:
<!DOCTYPE html><html><head><title></title><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></head><body><form action="{:U('verify/checkLogin')}" method="post"><div class="form-group has-feedback"><input type="text" name="verify" id="verify" placeholder="驗證碼" style="width:100px;" /><span style="right:120px;"></span><img class="verify" src="{:U(verify)}" alt="驗證碼" onClick="this.src=this.src+'?'+Math.random()" /></div><div class="col-xs-4"><button type="submit" >驗證</button></div></form></body></html>
2、使用ajax傳遞參數實現驗證,在控制器VerifyController.class.php中的代碼如下:
namespace Home\Controller;use Think\Controller;class VerifyController extends Controller {public function index() {$this->display();}public function checkLogin() {$verify=new \Think\Verify();$code=$_POST['code'];//ajax驗證碼擷取if($verify->check($code)){$this->ajaxReturn(1);}else{$this->ajaxReturn(0);}}public function verify(){// 執行個體化Verify對象$verify = new \Think\Verify();// 配置驗證碼參數$verify->fontSize = 14; // 驗證碼字型大小$verify->length = 4; // 驗證碼位元$verify->imageH = 34; // 驗證碼高度$verify->useImgBg = true; // 開啟驗證碼背景$verify->useNoise = false; // 關閉驗證碼幹擾雜點$verify->entry();}}
視圖Verify/index.html中的代碼如下:
<!DOCTYPE html><html><head><title></title><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><script src="__JS__/jquery-2.1.0.min.js" ></script></head><body><form action="{:U('verify/checkLogin')}" method="post"><div class="form-group has-feedback"><input type="text" name="verify" id="verify" placeholder="驗證碼" style="width:100px;" /><span style="right:120px;"></span><img class="verify" src="{:U(verify)}" alt="驗證碼" onClick="this.src=this.src+'?'+Math.random()" /></div><div class="col-xs-4"><button type="button" id="ver">驗證</button></div></form><script>$(document).ready(function(){/*ajax驗證碼*/$("#ver").click(function(){var code=$("#verify").val();//擷取輸入驗證碼var url=$('form').attr('action');//擷取表單action的值$.ajax({type:"post",url:url,data:{"code":code},error:function(request){alert("ajax錯誤");},success:function(data){if(data){alert("正確")}else{alert('錯誤')}}});});});</script></body></html>
在第2種方法,不要忘記下載jquery.min.js檔案下載地址:http://www.jq22.com/jquery-info122
在設定檔Common/conf/config.php中配置地址:
return array( /*地址替換*/'TMPL_PARSE_STRING'=>array( '__JS__'=>__ROOT__.'/Public/JS',),);
