php mysql數據庫得到的價格總計

我已經使用php代碼與mysql數據庫顯示數據到html表，我在listview上使用過濾器，現在我是堆棧與得到的價格過濾後的列表總數。我用php代碼不夠好，我用php或sql犯了錯誤嗎？php mysql數據庫得到的價格總計

MySQL表：

ID INT - 名VARCHAR - 代碼VARCHAR - 價格INT

這裏是我到目前爲止的代碼：

<?php 

if(isset($_POST['search'])) 
{ 
$valueToSearch = $_POST['valueToSearch']; 
// search in all table columns 
// using concat mysql function 
$query = "SELECT * FROM `toy` WHERE CONCAT(`id`, `name`, `code`, `price`) 
LIKE '%".$valueToSearch."%'"; 
$search_result = filterTable($query); 

} 
else { 
$query = "SELECT * FROM `toy` LIMIT 5"; 
$search_result = filterTable($query); 
} 

// function to connect and execute the query 
function filterTable($query) 
{ 
$connect = mysqli_connect("localhost", "user", "pass", 
"database"); 
$filter_Result = mysqli_query($connect, $query); 
return $filter_Result; 
} 

?> 

<!DOCTYPE html> 
<html> 
<head> 
    <title>Wu</title> 
    <link href="style.css" type="text/css" rel="stylesheet" /> 

</head> 
<body> 

    <div id="toys-grid"> 
     <div class="search-box"> 
     <br>    
     <form action="index.php" method="post"> 
     <input type="text" name="valueToSearch" placeholder="Name To Search"> 
     <br><br> 
     <input type="submit" name="search" value="Filter"><br><br> 
     </div> 

     <table cellpadding="10" cellspacing="1"> 

    <thead> 
      <tr> 
       <th>Id</th> 
       <th>First Name</th> 
       <th>Code</th> 
       <th>Price</th> 
      </tr> 
    </thead> 
    <!-- populate table from mysql database --> 
      <?php while($row = mysqli_fetch_array($search_result)):?> 
      <tbody> 
      <tr> 
       <td><?php echo $row['id'];?></td> 
       <td><?php echo $row['name'];?></td> 
       <td><?php echo $row['code'];?></td> 
       <td><?php echo $row['price'];?></td> 
      </tr> 
      </tbody> 
      <?php endwhile;?> 

      <thead> 
      <tr> 
      <th> Total </th> 
     <th> 
     <?php 
     $results = mysql_query('SELECT SUM(price) FROM toy'); 
     $results->execute(); 
     for($i=0; $rows = $results->fetch(); $i++){ 
     echo $rows['SUM(price)']; 
     } 
     ?> 
     </th> 
     </tr> 
     </thead> 
     </table> 
     </form> 
    </div> 
</body>

我很欣賞你幫助...

沒有明白你想要什麼？你想要總數？ –

你錯過了'我'在** mysql_query（'選擇SUM（價格）從玩具'）; **和你的for循環得到錯誤的語法第二個參數。更好地使用while語句。 E.G：while（$ rows = mysqli_fetch_array（$ result））{echo $ rows ['SUM（price）']; } –

無需執行查詢以獲取總和。你可以使用php

<table cellpadding="10" cellspacing="1"> 

    <thead> 
      <tr> 
       <th>Id</th> 
       <th>First Name</th> 
       <th>Code</th> 
       <th>Price</th> 
      </tr> 
    </thead> 
    <!-- populate table from mysql database --> 
    <?php $sum = 0; ?> 
    <?php while($row = mysqli_fetch_array($search_result)):?> 
    <tbody> 
    <tr> 
     <td><?php echo $row['id'];?></td> 
     <td><?php echo $row['name'];?></td> 
     <td><?php echo $row['code'];?></td> 
     <td><?php echo $row['price'];?></td> 
     <?php 
     $sum += $row['price']; 
     ?> 
    </tr> 
    </tbody> 
    <?php endwhile;?> 

    <thead> 
     <tr> 
     <th> Total </th> 
     <th> 
     <?php 
     echo $sum; 
     ?> 
     </th> 
     </tr> 
    </thead> 
</table>
