Php 从移动应用请求的数据库查询结果

我正在将hybrid应用程序连接到web应用程序的API，以便在用户请求搜索后查询某些数据。我正在使用Onsen UI构建应用程序

服务器端的API代码应返回用户按其名称搜索的商户。结果应仅为1个商户（餐厅名称）

基本上，我从应用程序中发送一个参数名称“merchant”，API应该获取该参数，并在数据库中搜索一个名为“view_merchant”列“restaurant_name”的表，比较数据库中的名称请求，然后将其返回给应用程序

我添加了JS函数

var search_restaurant;
var search_cuisine;
var search_food;

    $("#r").val( getStorage("search_restaurant") );
    $("#c").val( getStorage("search_cuisine") );
    $("#f").val( getStorage("search_food") );

function searchMerchantName()
{           

  var r = $('#r').val();  

  /*clear all storage*/
  setStorage("search_restaurant",r);   
  removeStorage('merchant_id');
  removeStorage('shipping_address');  
  removeStorage('merchant_id');
  removeStorage('transaction_type');
  removeStorage('merchant_logo');
  removeStorage('order_total');
  removeStorage('merchant_name');
  removeStorage('total_w_tax');
  removeStorage('currency_code');
  removeStorage('paymet_desc');
  removeStorage('order_id');   
  removeStorage('order_total_raw');   
  removeStorage('cart_currency_symbol');     
  removeStorage('paypal_card_fee');   

  if(r!=""){
      var options = {     
          merchant:r,                 
          closeMenu:true,
          animation: 'slide'          
       };            
      menu.setMainPage('searchMerchants.html',options);

  } else{
     onsenAlert(   getTrans('Restaurant Name is required','merchant_is_required')  );
  }
}

function searchCuisine()
{           

  var c = $('#c').val();  

  /*clear all storage*/
  setStorage("search_cuisine",c);   
  removeStorage('merchant_id');

  } else{
     onsenAlert(   getTrans('Cuisine Type is required','cuisine_is_required')  );
  }
}

function searchFood()
{           

  var f = $('#f').val();  

  /*clear all storage*/
  setStorage("search_food",f);   
  removeStorage('merchant_id');

您的SQL语句将是：

SELECT * FROM view_merchant WHERE lower(restaurant_name)=?

---

您需要

toLowerCase（）

您传递的值

$this->data['merchant']

，这样您就可以找到餐厅，而不必考虑大小写。唯一的问题是，如果存在同名的记录，则会返回多个记录

你需要什么帮助？您需要PHP页面和从JS调用该页面的示例吗？这不是针对Onsen的，所以我不清楚您需要什么帮助。@Munsterlander是的，它与Onsen无关，它是PHP，我将用JS函数更新问题以进行检查。我需要的是查询请求的数据并将其发回给用户。您希望数据如何返回JSON对象或字符串？我发布了SQL语句，这取决于您希望如何返回数据。JSON对象是最常见的。

SELECT * FROM view_merchant WHERE lower(restaurant_name)=?
