Php 为不同的搜索选项调用不同的函数

亲爱的朋友，我有两个功能，将来可能会有更多功能，但问题是，当用户在同一个文本字段中根据邮政编码搜索酒店时，我希望使用该功能 应该调用hotel_by_postel_代码（$textvalue），当我基于国家搜索时，则调用函数 应按国家/地区致电酒店（$textvalue）。下面是应该显示结果的代码，但是它根本不应该显示结果

<?php require_once("includes/header.php");?>
<?php require_once("includes/connection.php")?>
<?php    
     if(isset($_POST['submit'])){
          $message =""; 
          $textvalue = $_POST['search'];
          if(empty($allhotels = hotel_by_postel_code($textvalue)) || empty($allhotels = hotel_by_country($textvalue))){
             $message = "There is no record in the database";
          } 

      }else{    
          $allhotels = select_all_hotels();
      } 
?>

您缺少

空

函数的右括号（右括号），——一个在OR前面，一个在条件末尾）
更改：

if(empty($allhotels = hotel_by_postel_code($textvalue) OR empty($allhotels = hotel_by_country($textvalue))

致：

接下来，我将这一行分成几行：

$allhotels1 = hotel_by_postel_code($textvalue);
$allhotels2 = hotel_by_country($textvalue);
echo "allhotels1 = $allhotels1; allhotels1 = $allhotels1\n";//for debug
if(empty($allhotels1) OR empty($allhotels2){...

---

最后一件事-你确定它应该是

或
而不是
和
？
我认为你的问题在于这个代码

if(is_numermic($textvalue))
   hotel_by_postel_code($textvalue)
else
  hotel_by_country($textvalue)

if(empty($allhotels = hotel_by_postel_code($textvalue)) || empty($allhotels = hotel_by_country($textvalue))){
    $message = "There is no record in the database";
}

首先，将
$allhotels
填入
hotel\u by\u postel\u代码（$textvalue）
。然后用
$allhotels=hotel\u by\u country（$textvalue）
覆盖它

另外，您应该将
|
替换为
&&
，因为您只希望在两个函数都不返回值时收到消息

试试看

$allhotels = hotel_by_postel_code($textvalue);
if(empty($allhotels)) {
    $allhotels = hotel_by_country($textvalue);
    if(empty($allhotels)) {
         $message = "There is no record in the database";
    }
}

经过多次尝试和错误，我终于找到了解决方案，下面是我发现的最好的选择，也许将来有人会遇到同样的问题。需要记住的一点是，IF和Else中的选项可以轻松地移动到单独文件中的函数中。我还添加了一个Html菜单来选择我要搜索的选项类型，在本例中，它是filter菜单

<?php 
error_reporting(E_ALL);
ini_set('display_errors','1');?>
<?php require_once("includes/header.php");?>
<?php require_once("includes/connection.php")?>
<?php

     if(isset($_POST['search']) &&  $_POST['search']!= "") {

                 if($_POST['filter'] == "HotelName"){
                 $search = $_POST['search'];

                  $sqlquery = "SELECT * FROM Hotels WHERE hotel_name LIKE '%$search%' OR description LIKE '%$search%'";
                  $allhotels = mysql_query($sqlquery, $connection) or die("Sorry Something wrong".mysql_error());


                 }else if($_POST['filter'] == "country"){

                 $search = $_POST['search'];

                  $sqlquery = "SELECT * FROM Hotels WHERE country LIKE '%$search%' OR hotel_address LIKE '%$search%'";
                  $allhotels = mysql_query($sqlquery, $connection) or die("Sorry Something wrong".mysql_error());



                 }else if($_POST['filter'] == "Postal"){
                 $search = $_POST['search'];

                  $sqlquery = "SELECT * FROM Hotels WHERE hotel_postal_code LIKE '%$search%'";
                  $allhotels = mysql_query($sqlquery, $connection) or die("Sorry Something wrong".mysql_error());
                 }

      }

或者| |这不是原因，因为我尝试了这两种方法，但仍然不起作用。@SalimAlmughairi我不理解您的最后一条评论记录正在被调用，但问题是选择其中一个，而不是两个，或者什么都并没有。若我使用两个变量，当我想显示这意味着如果var1是while（var1=fetch…）和while（var2=fetch…），则每个条件必须有2个while循环。你看，我这样做的方式是，如果其中一个有效，那么它仍然适用于相同的，而贝娄。感谢您的支持，其中没有一个是数字，一个是字母数字，另一个是文本。我正在检查第一个是否为空，然后将第二个分配给同一个varibel。因此，您认为可能存在什么问题。问题是，即使第一个变量不为空，您也会覆盖该变量。我在回答中添加了一些代码。
$allhotels = hotel_by_postel_code($textvalue);
if(empty($allhotels)) {
    $allhotels = hotel_by_country($textvalue);
    if(empty($allhotels)) {
         $message = "There is no record in the database";
