PHPをJavascriptに埋め込む

Question

Countriesを選択すると、クエリの結果がアルファベットで表示され、Numbersを選択した場合は、降順の数値に基づいて一覧表示されるようにPHPをJavascriptに埋め込む必要があります。

調査したところ、私はthis（echoの概念を自分のコードに適用しましたが動作していないようです）その後

$querytest = "select x , COUNT(*) from(select `staffbirthplace` as x from staffbirthdetails where staffemailid IN(SELECT staffemailid FROM staff where orgid='" . $orgId . "' AND deptname='" . $deptName . "' AND teamname='" . $teamName . "')) as temptable group by x order by count(*) ASC "; 

、私はHTMLでドロップダウンを持っている：出産の出力スタッフの国が昇順で（多くの国で生まれたスタッフのいないが）ことを、私は次のクエリは、PHPで書かれている

<form> 
    <label for="sortorder">Sort by:</label> 
    <select id="sortByDropdown" onchange="sortBy(this);"> 
     <option value="alphabatically">Countries</option> 
     <option value="numbers">Number</option> 
    </select> 
</form> 

さらに、私はJavascript機能を持っているsortBy()

function sortBy(){ 
    var sortByDrpdownDiv = document.getElementById('sortByDropdown'); 

if (sortByDrpdownDiv[sortByDrpdownDiv.selectedIndex].value == 'numbers'){ 
    alert("yo in if statement"); 
    <?php $querytest = "select x , COUNT(*) from(select `staffbirthplace` as x from staffbirthdetails where staffemailid IN(SELECT staffemailid FROM staff where orgid='" . $orgId . "' AND deptname='" . $deptName . "' AND teamname='" . $teamName . "')) as temptable group by x order by count(*) DESC "; 
    $result = mysql_query($querytest); 

    while ($row = mysql_fetch_assoc($result)) { 
      echo "<b>"; 
      echo $row['x']; 
      echo ": </b>&nbsp;"; 
      echo $row['COUNT(*)']; 
      echo "<br/>"; 
     }?> 
    document.getElementById('staffbirthplaces').innerHTML = <?php echo $row?>; 
    } 
} 

最初にNumbersに行くのは、同じロジックがCountriesに適用されるためです。どんな助けもありがとう

私はついにそれをしました！ IF statementの代わりにswitchを使用してください。以下のコードです：

function sortByAlphabetsOrNumbers(obj){ 

    var selectedValue = obj.options[obj.selectedIndex].value 
switch(selectedValue) 
{ 
    case "numberOfStaff": 
     document.getElementById('sortBy').innerHTML = 
     "<?php 
      include 'connection.php'; 

      $staffNumbersDesc = "select x , COUNT(*) from(select `staffbirthplace` as x from staffbirthdetails where staffemailid IN(SELECT staffemailid FROM staff where orgid='" . $orgId . "' AND deptname='" . $deptName . "' AND teamname='" . $teamName . "')) as temptable group by x order by count(*) DESC"; 
      $result = mysql_query($staffNumbersDesc);    
      while ($row = mysql_fetch_assoc($result)) 
      { 
       echo "<b>"; 
       echo $row['x']; 
       echo ": </b>&nbsp;"; 
       echo $row['COUNT(*)']; 
       echo "<br/>"; 
       } 
     ?>"; 
     document.getElementById('birthCountriesAlphabaticalOrder').style.display = "none"; 
     break; 

    case "countries": 
     document.getElementById('sortBy').innerHTML = 
     "<?php 
      include 'connection.php'; 

      $alphabaticalOrder = "select x , COUNT(*) from(select `staffbirthplace` as x from staffbirthdetails where staffemailid IN(SELECT staffemailid FROM staff where orgid='" . $orgId . "' AND deptname='" . $deptName . "' AND teamname='" . $teamName . "')) as temptable group by x"; 
      $result = mysql_query($alphabaticalOrder);    
      while ($row = mysql_fetch_assoc($result)) 
      { 
       echo "<b>"; 
       echo $row['x']; 
       echo ": </b>&nbsp;"; 
       echo $row['COUNT(*)']; 
       echo "<br/>"; 
       } 
     ?>"; 
     document.getElementById('birthCountriesAlphabaticalOrder').style.display = "none"; 
     break; 
} 
}; 

はそれが誰か
