使用数据库中的数据填充列表框

Question

<?php 
ini_set("display_errors","on"); 
$conn = new COM("ADODB.Connection"); 
    try { 
    $myServer = "WTCPHFILESRV\WTCPHINV"; 
    $myUser = "sa"; 
    $myPass = "P@ssw0rd"; 
    $myDB = "wtcphitinventory"; 
    $connStr = "...conn string..."; 
    $conn->open($connStr); 
     if (! $conn) { 
      throw new Exception("Could not connect!"); 
     } 
    } 
    catch (Exception $e) { 
     echo "Error (File:): ".$e->getMessage()."<br>"; 
    } 
if (!$conn) 
    {exit("Connection Failed: " . $conn);} 
    $sql_exp = "select * from dbo.PC"; 
    $rs = $conn->Execute($sql_exp); 
echo "<table><tr><th>Desktop Number</th></th></tr>"; 
    while (!$rs->EOF) { 
     set_time_limit(0);  
     echo "<td>CP # <br>".$rs->Fields("PC_Number")."</td>";   
     $rs->MoveNext(); 
    } 
    echo "</table>"; 
    $rs->Close(); 
     ?> 

我想有一个列表框，而不是从数据库打印所有PC_Number的数据。我所能做的就是回应它，即时插入选择。我希望有一个表单方法帖子和一个select（listbox）

Answer 1

在while语句中创建列表框。

echo "<table border='1' cellpadding='1' cellspacing='0' id='rounded-corner'><tr><th>Desktop Number</th></th></tr>"; 


    echo "<tr><td><select name='selectionField'>"; 
    while (!$rs->EOF) { 
     set_time_limit(0); 
     echo "<option value=".$rs->Fields('PC_Number')." >".$rs->Fields('PC_Number')."</option>"; 
     $rs->MoveNext(); 
    } 
    echo "</td></tr></table>";
