在动态 html+php table 中显示 select 选项列表（下拉列表）

Question

正如您在这张图片中看到的，我扫描产品的条形码，插入 mysql table 并通过自动刷新将 mysql table 检索到此页面.每次我扫描不同的产品时，都会根据 mysql table 添加新行。

使用这些代码，我检索 mysql table 并在 html 中回显 table:

<table id="dataTable" class="table table-condensed table-bordered" style="margin-top:0px">
    <tbody>
    <?php
    $sat_fatura_no = $_GET['sat_fatura_no'];
    $liste_cek = @mysql_query("SELECT * FROM alisfat_listesi WHERE fatura_no = '".$sat_fatura_no."'");
    while ($a= mysql_fetch_array($liste_cek)){
        $stok_kodu2 = $a['stok_kodu'];

        $isim_cek = mysql_query("SELECT * FROM stoklar WHERE sto_RECno = '".$stok_kodu2."'");
        while ($isim_al=mysql_fetch_array($isim_cek)){
            $urun_isim = $isim_al['sto_isim'];
        }
        $kdv    = $a['kdv'];

        $kdv_cek = mysql_query("SELECT * FROM kdvler WHERE kdv_id = '".$kdv."'");
        while ($kdv_al = mysql_fetch_array($kdv_cek)){
            $kdv_isim = $kdv_al['kdv_isim'];    
        }

        $kdv_cek1 = mysql_query("SELECT * FROM kdvler");
        while ($kdv_al1 = mysql_fetch_array($kdv_cek1)){
            $kdv_id1    = $kdv_al1['kdv_id'];
            $kdv_isim1  = $kdv_al1['kdv_isim'];
        }

        echo '<tr>
            <td width="5%"><a href="satir_sil.php?stok_kodu='.$stok_kodu2.'&sat_fatura_no='.$sat_fatura_no.'"><button class="btn btn-mini btn-danger  input1">Sil</button></a></td>

            <td width="25%"><input class="input1" type="hidden" name="sth_stok_kod[]" value="'.$stok_kodu2.'" readonly>'.$urun_isim.'</td>

            <td width="10%"><input style="text-align:center" class="input1" type="text" name="sth_adet[]" value="" required></td>

            <td width="10%">
                <select style="margin: 0 !important; padding: 0 !important; width:100%" name="sth_birim[]" required>
                    <option value="" selected>Seçiniz</option>
                    <?php $brim2_bul = mysql_query("SELECT * FROM birimler");
                    while($brim2_cek = mysql_fetch_array($brim2_bul)){
                        echo "<option ";
                        echo "value="".$brim2_cek["birim_id"]."">". $brim2_cek["birim_isim"]."</option>";
                    } ?>
                 </select>
            </td>

            <td width="10%"><input class="input1" type="text" id="sth_birim_fiyat" name="sth_birim_fiyat[]" required></td>

            <td width="10%">
                <select style="margin: 0 !important; padding: 0 !important; width:100%" name="sth_kdv" required>
                    <option value="<?php echo $stok_vergisi; ?>" selected><?php echo $stok_vergisi; ?></option>
                    <?php $kdv2_bul = mysql_query("SELECT * FROM kdvler");
                    while($kdv2_cek = mysql_fetch_array($kdv2_bul)){
                        echo '<option ';
                        echo 'value="'.$kdv2_cek['kdv_isim'].'">' .$kdv2_cek['kdv_isim'].'</option>';
                    } ?>
                 </select>
            </td>

            <td width="10%"><input class="input1" type="text" id="sth_iskonto1" name="sth_iskonto1[]" required></td>

            <td width="10%"><input class="input1" type="text" id="sth_iskonto2" name="sth_iskonto2[]" required></td>    

            <td width="10%"><input class="input1" type="text" id="sth_tutar" name="sth_tutar[]" required></td>
        </tr>';
    } ?>
    </tbody>
</table>

我唯一无法修复的部分是 SELECT OPTION 部分。通常我可以使用这些 select 选项 php 代码检索 mysql table 的每一行，但是当我将它们放入 php echo 时，通常我不能从数据库中检索任何值。

所以有人知道我如何让这些 select 下拉菜单在 php echo 中保持活跃吗？

您不应在 echo 字符串中使用 PHP 标签。将它们分开。先结束echo字符串语句，再使用PHP逻辑语句。我已经更新了您的代码：

<table id="dataTable" class="table table-condensed table-bordered" style="margin-top:0px">
    <tbody>
    <?php
    $sat_fatura_no = $_GET['sat_fatura_no'];
    $liste_cek = @mysql_query("SELECT * FROM alisfat_listesi WHERE fatura_no = '".$sat_fatura_no."'");
    while ($a= mysql_fetch_array($liste_cek)){
        $stok_kodu2 = $a['stok_kodu'];

        $isim_cek = mysql_query("SELECT * FROM stoklar WHERE sto_RECno = '".$stok_kodu2."'");
        while ($isim_al=mysql_fetch_array($isim_cek)){
            $urun_isim = $isim_al['sto_isim'];
        }
        $kdv    = $a['kdv'];

        $kdv_cek = mysql_query("SELECT * FROM kdvler WHERE kdv_id = '".$kdv."'");
        while ($kdv_al = mysql_fetch_array($kdv_cek)){
            $kdv_isim = $kdv_al['kdv_isim'];    
        }

        $kdv_cek1 = mysql_query("SELECT * FROM kdvler");
        while ($kdv_al1 = mysql_fetch_array($kdv_cek1)){
            $kdv_id1    = $kdv_al1['kdv_id'];
            $kdv_isim1  = $kdv_al1['kdv_isim'];
        }

        echo '<tr>

                    $kdv2_bul = mysql_query("SELECT * FROM kdvler");
                    while($kdv2_cek = mysql_fetch_array($kdv2_bul)){
                        echo '<option value="'.$kdv2_cek['kdv_isim'].'">' .$kdv2_cek['kdv_isim'].'</option>';

试试这个，希望它能解决您的问题。
