從移動應用程序請求數據庫的查詢結果

Question

我將混合應用程序連接到Web應用程序的API以在用戶搜索請求後查詢某些數據。我正在使用Onsen UI來構建應用程序。

服務器端的API代碼應該返回用戶通過名稱搜索的商家。結果應該是隻有1個商戶（餐廳名字）

public function actionSearchMerchant() 
{  
    if (!isset($this->data['merchant'])){ 
     $this->msg=$this->t("Restaurant Name is required"); 
     $this->output(); 
    } 

    if (isset($_GET['debug'])){ 
     dump($this->data); 
    } 

    if (!empty($this->data['merchant'])){ 

      $DbExt=new DbExt; 
      $DbExt->qry("SET SQL_BIG_SELECTS=1"); 

      $total_records=0; 
      $data=''; 

      $and="AND status='active' AND is_ready='2' "; 

      $services_filter=''; 
      if (isset($this->data['services'])){ 
       $services=!empty($this->data['services'])?explode(",",$this->data['services']):false;     
       if ($services!=false){ 
        foreach ($services as $services_val) { 
         if(!empty($services_val)){ 
          $services_filter.="'$services_val',"; 
         } 
        } 
        $services_filter=substr($services_filter,0,-1); 
        if(!empty($services_filter)){ 
         $and.=" AND service IN ($services_filter)"; 
        } 
       } 
      } 

      $filter_cuisine=''; 
      if (isset($this->data['cuisine_type'])){ 
       $cuisine_type=!empty($this->data['cuisine_type'])?explode(",",$this->data['cuisine_type']):false; 
       if ($cuisine_type!=false){ 
        $x=1; 
        foreach (array_filter($cuisine_type) as $cuisine_type_val) {        
         if ($x==1){ 
          $filter_cuisine.=" LIKE '%\"$cuisine_type_val\"%'"; 
         } else $filter_cuisine.=" OR cuisine LIKE '%\"$cuisine_type_val\"%'"; 
         $x++; 
        }   
        if (!empty($filter_cuisine)){ 
         $and.=" AND (cuisine $filter_cuisine)"; 
        }   
       } 
      } 

      $rname=$this->data['merchant']; 

      $stmt="SELECT * FROM 
        {{view_merchant}} 
        WHERE 
        restaurant_name LIKE '%\"$rname\"%' 

        SELECT a.*,count(*) as total_records FROM 
        {{view_merchant}} a 
        WHERE 
        restaurant_name LIKE '%\"$rname\"%' 
        $and 
        LIMIT 0,100 
      "; 


      if (isset($_GET['debug'])){ 
       dump($stmt); 
      } 

      if ($res=$DbExt->rst($stmt)){  

       $stmtc="SELECT FOUND_ROWS() as total_records"; 
       if ($resp=$DbExt->rst($stmtc)){      
        $total_records=$resp[0]['total_records']; 
       }     

       $this->code=1; 
       $this->msg=$this->t("Successful"); 

       foreach ($res as $val) {   

        $minimum_order=getOption($val['merchant_id'],'merchant_minimum_order'); 
        if(!empty($minimum_order)){ 
         $minimum_order=displayPrice(getCurrencyCode(),prettyFormat($minimum_order));      
        } 

        $delivery_fee=getOption($val['merchant_id'],'merchant_delivery_charges'); 
        if (!empty($delivery_fee)){ 
         $delivery_fee=displayPrice(getCurrencyCode(),prettyFormat($delivery_fee)); 
        } 

        /*check if mechant is open*/ 
        $open=AddonMobileApp::isMerchantOpen($val['merchant_id']); 

        /*check if merchant is commission*/ 
        $cod=AddonMobileApp::isCashAvailable($val['merchant_id']); 
        $online_payment=''; 

        $tag=''; 
        $tag_raw=''; 
        if ($open==true){       
         $tag=$this->t("open"); 
         $tag_raw='open'; 
         if (getOption($val['merchant_id'] ,'merchant_close_store')=="yes"){ 
          $tag=$this->t("close"); 
          $tag_raw='close'; 
         } 
         if (getOption($val['merchant_id'] ,'merchant_preorder')==1){ 
          $tag=$this->t("pre-order"); 
          $tag_raw='pre-order'; 
         } 
        } else { 
         $tag=$this->t("close"); 
         $tag_raw='close'; 
         if (getOption($val['merchant_id'] ,'merchant_preorder')==1){ 
          $tag=$this->t("pre-order"); 
          $tag_raw='pre-order'; 
         } 
        }     


        $data[]=array(
         'merchant_id'=>$val['merchant_id'], 
         'restaurant_name'=>$val['restaurant_name'], 
         'address'=>$val['street']." ".$val['city']." ".$val['state']." ".$val['post_code'], 
         'ratings'=>Yii::app()->functions->getRatings($val['merchant_id']), 
         'cuisine'=>AddonMobileApp::prettyCuisineList($val['cuisine']), 
         'delivery_fee'=>$delivery_fee,       
         'minimum_order'=>$minimum_order, 
         'delivery_est'=>getOption($val['merchant_id'],'merchant_delivery_estimation'), 
         'is_open'=>$tag, 
         'tag_raw'=>$tag_raw, 
         'payment_options'=>array(
         'cod'=>$cod, 
         'online'=>$online_payment 
        ),       
         'logo'=>AddonMobileApp::getMerchantLogo($val['merchant_id']), 
         'offers'=>AddonMobileApp::getMerchantOffers($val['merchant_id']) 
        ); 
       }     

       $this->details=array(
        'total'=>$total_records, 
        'data'=>$data 
       ); 

      } else $this->msg=$this->t("No restaurant found"); 
     } else $this->msg=$this->t("Error has occurred failed restaurant info"); 
    } else $this->msg=$this->t("Restaurant Name is required"); 
    $this->output(); 
} 

基本上我發送從應用程序的參數名「商人」的API應該得到和搜索的表到所謂的「view_merchant」列「數據庫restaurant_name「，然後比較數據庫中所請求的名稱，然後將其返回至找到的應用程序。

編輯我添加了JS功能

Answer 1

你的SQL語句將是：

SELECT * FROM view_merchant WHERE lower(restaurant_name)=? 

你會想你的toLowerCase()傳遞的值$this->data['merchant']所以你不管外殼的發現餐廳。唯一的問題是這將返回多個記錄，如果有同名的。
