我正在尝试将数据从数据库中提取到选择框中

Question

我正在尝试将数据从数据库中提取到选择框中，但是当数据被拉出时，它会进入一个“td”而不是单独的td。我正在努力实现如下所示的结果

但我一直得到这个结果

这是我的代码

<?php
$data_array = array();
$result2 = mysql_query("SELECT * FROM `firefightersonscene` 
                        JOIN `firefighterinfo` ON `firefightersonscene`.`FireFighterInfo_fighterID` = `firefighterinfo`.`fighterID` 
                        JOIN `stationlocation` ON `firefighterinfo`.`StationLocation_locationID`=`stationlocation`.`locationID` 
                        WHERE `IncidenceOfFire_incidentID`='$getIncID' ORDER BY `firstName`");

if(mysql_num_rows($result2) > 0)
{    
    while($rows2 = mysql_fetch_object($result2))
    {
        $data_array[] = $rows2;
    }

您需要将整个表格行放在循环中。您还需要添加一个变量来为您计算行号。

<?php 
$row =1;
foreach($data_array as $rows2):
?>
<tr>
    <td class="count"><?php echo $row; ?></td>
    <td>
        <?php    
             $fighterID = $rows2->FireFighterInfo_fighterID; 
            $results = mysql_query("SELECT `fighterID`, `firstName`, `middleName`, `lastName`, `stationlocation`.`exactlocation` 
                                    FROM `firefighterinfo` 
                                    JOIN `stationlocation` ON `firefighterinfo`.`StationLocation_locationID`=`stationlocation`.`locationID` ORDER BY `firstName`");               
            echo '<select name="fireman[]" required><option value=""></option>';
            while($row = mysql_fetch_array($results))
            {
                if($row['fighterID'] == $fighterID)
                    echo '<option selected>'. $row['firstName']." ".$row['middleName']." ".$row['lastName'].", ".$row['exactlocation'].'</option>';
                else
                    echo '<option>'. $row['firstName']." ".$row['middleName']." ".$row['lastName'].", ".$row['exactlocation'].'</option>';

            }// end while
            echo '</select><br>';

        ?> 
    </td>
    <td>
        <input type="button" value="X" class="removeVar"/>
    </td>
</tr>
<?php
    $row++;
    endforeach;
?>
