Showing select option list (Dropdown) in dynamic html+php table

Question

As you can see in this image, i scan barcodes of products, insert into mysql table and retrieve that mysql table into this page by refreshing automatically. Everytime i scan a different product that list add new rows accoridng to the mysql table.

With these codes i retrieve mysql table and echo in html 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>

        </tr>';
    } ?>
    </tbody>
</table>

The only part that i couldn't fix is those SELECT OPTION parts. Normally i can retrieve every row of mysql table with these select option php codes BUT when i put them inside php echo, as a normal i can not retrieve any values from database.

So anybody has any idea how i can make these select dropdown alive inside php echo?

You should not use PHP tags inside echo string. Keep them separate. End the echo string statement first and then use PHP logical statements. I have updated your code:

<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'];

Try this, hope it will resolve your issue.
