如何找到範圍之內的複選框

Question

我有一個名爲列重量在我的表佔。我需要從該列像取的值，

當用戶從40重量點擊 - 100，它需要用來顯示所有重量的人在40和100之間

這是我的HTML代碼，

<div class="float-right span35"> 
    <form class="list-wrapper search-form" method="get" action="{{CONFIG_SITE_URL}}/index.php"> 
     <div class="list-header"> 
      Talent Search 
     </div> 
       <h4 style="margin-left: 10px; color: gray;">Weight</h4> 
       <fieldset id="weight"> 
        <input type="checkbox" name="weight" value="1" {{WEIGHT_1}}/>Below 40<br> 
        <input type="checkbox" name="weight" value="2" {{WEIGHT_2}}/>40-70<br> 
        <input type="checkbox" name="weight" value="3" {{WEIGHT_3}}/>70-100<br> 
        <input type="checkbox" name="weight" value="4" {{WEIGHT_4}}/>Above 100<br> 
       </fieldset> 
       <br/> 
       <input style="margin-left: 10px" type="submit" name="submit" value="search"/><br><br> 
       <input type="hidden" name="tab1" value="search"> 
     </form> 
</div> 

這是我的PHP代碼，

if(isset($_GET['submit'])){ 


    $weight = ($_GET['weight'])? $escapeObj->stringEscape($_GET['weight']): NULL; 

    $sql = "SELECT id FROM `".DB_ACCOUNTS."` WHERE `id` IS NOT NULL "; 

    if(is_numeric($weight) && $weight != NULL){ 
     $sql .= "AND `weight` IN (".$weight.")"; 
     $is_weight = true; 
    } 

    $sql .= " ORDER BY `id` ASC"; 

    } 
    if($is_weight){ 
     $themeData['weight_'.$weight] = 'checked'; 
    } 

    $query = $conn->query($sql); 
    if($query->num_rows > 0){ 
      while($fetch = $query->fetch_array(MYSQLI_ASSOC)){ 
       $get[] = $fetch['id']; 
      } 

      $i = 0; 
      $listResults = ''; 

      $themeData['page_title'] = "Advanced Search - ".$lang['search_result_header_label']; 
      foreach($get as $row){ 
       $timelineObj = new \SocialKit\User(); 
       $timelineObj->setId($row); 
       $timeline = $timelineObj->getRows(); 

       $themeData['list_search_id'] = $timeline['id']; 
       $themeData['list_search_url'] = $timeline['url']; 
       $themeData['list_search_username'] = $timeline['username']; 
       $themeData['list_search_name'] = $timeline['name']; 
       $themeData['list_search_thumbnail_url'] = $timeline['thumbnail_url']; 

       $themeData['list_search_button'] = $timelineObj->getFollowButton(); 

       $listResults .= \SocialKit\UI::view('search/list-each'); 
       $i++; 
      } 
      $themeData['list_search_results'] = $listResults; 

    } 

} 

此代碼幾乎是從表中的單件重量工作。但是我需要在代碼中提到的複選框值之間創建一個範圍。我需要更新代碼嗎？

在PHP代碼變化

if(is_numeric($weight) && $weight != NULL){ 
    $sql .= "AND `weight` IN (".$weight.")"; 
    $is_weight = true; 
} 

要

if(is_numeric($weight) && $weight != NULL){ 
    if($weight==1){ 
     $sql .= "AND weight<40"; 
    } 
    if($weight==2){ 
     $sql .= "AND weight>=40 AND weight <=70"; 
    } 
    if($weight==3){ 
     $sql .= "AND weight>70 AND weight <=100"; 
    } 
    if($weight==4){ 
     $sql .= "AND weight>100"; 
    } 
    $is_weight = true; 
} 

而且，我建議使用無線電而不是複選框與複選框，如果選擇一個以上的權重選擇一個值會迷路。

試試這個，希望這個作品，所以你不會讓你的代碼大的變化

使用radion按鈕

<input type="radio" name="weight" value="0" {{WEIGHT_1}}/>Below 40<br> 
<input type="radio" name="weight" value="1" {{WEIGHT_2}}/>40-70<br> 
<input type="radio" name="weight" value="2" {{WEIGHT_3}}/>70-100<br> 
<input type="radio" name="weight" value="3" {{WEIGHT_4}}/>Above 100<br> 

您可以在PHP中加一個變量數組

$arrayWeight = ["`weight` >= 0 && `weight` <=40", 
       "`weight` >= 40 && `weight` <=70", 
       "`weight` >=70 && `weight` <=100", 
       "`weight` >= 100"]; 

// $arrayWeight[$weight] = $arrayWeight[1]; 
// $arrayWeight[1] = 'weight' >= 0 && 'weight' <=40 a string 

在這一行add add this

if(is_numeric($weight) && $weight != NULL) 
    { 
     $sql .= "AND ".$arrayWeight[$weight].")"; //sample $arrayWeight[1] = 'weight' >= 0 && 'weight' <=40 

     //" SELECT id FROM `".DB_ACCOUNTS."` WHERE `id` IS NOT NULL AND 'weight' >= 0 && 'weight' <=40 

     $is_weight = true; 
    }
