如何在表格的TD中填充组合框

Question

I want to retrieve some data from the database and show them in a table, i need to make one field Order_Status to be as a combo box, its data is filled from another table and to add in the beginning of the combo the result of the row returned from the database.

Data Sample from database

The data needed to be like the below, in the red section to be combobox. Required Result

The problem is that i couldn't put the result for the field Order_status to appear as a combo box in the td of the table

$stmt ="SELECT distinct Order_ID,Customer_ID,Required_Date,Order_Status FROM Orders where Required_Date between '".$SDate."' and '".$EDate."'";
$row = $conn->query($stmt)->fetchall(PDO::FETCH_ASSOC);

if (count($row) > 0)
{
    $output.='<hr />
            <table class="table1">
                <tr>
                    <th>Order No.</th>
                    <th>Customer Name</th>
                    <th>Order Details</th>
                    <th>Delivery Date</th>
                    <th>Order Status</th>
                </tr>
    ';
    foreach ($conn->query($stmt) as $rows) 
    {
        //Getting Customer Name
        $sql="SELECT nick_name_ FROM Customers where Cust_id='".$rows["Customer_ID"]."'";
        $result=$conn->query($sql)->fetch(PDO::FETCH_ASSOC);

        //Getting Order Data
        $query="SELECT * FROM Order_Product where Order_ID='".$rows["Order_ID"]."'";

        foreach ($conn->query($query) as $results) 
        {
            $newsql="SELECT Category_Name from Categories where Category_ID='".$results['Category_ID']."'";
            $newresult=$conn->query($newsql)->fetch(PDO::FETCH_ASSOC);
            $CatName=$newresult['Category_Name'];

            $newsql="SELECT Product_Name from Products where Product_ID='".$results['Product_ID']."'";
            $newresult=$conn->query($newsql)->fetch(PDO::FETCH_ASSOC);
            $ProName=$newresult['Product_Name'];

            $output.='
            <tr>
                <td>'.$rows['Order_ID'].'</td>
                <td>'.$result['nick_name_'].'</td>
                <td>'.$CatName.",".$ProName." ".$results['Amount'].'</td>
                <td>'.$rows['Required_Date'].'</td>
            ';
            $stmt = "SELECT * FROM Order_Status WHERE Status_Name !='".$rows['Order_Status']."'";
            //$res = $conn->query($sql)->fetch(PDO::FETCH_ASSOC);

            foreach ($conn->query($stmt) as $res) 
            {

                $output.='<td>'
                ?>
                    <option value="<?php echo $res['Status_ID']; ?>"><?php echo $res['Status_Name']; ?></option>
                <?php
                '</td>
                </tr>
                ';
            }

        }
    }

    $output.='</table>';
    $bool_is_data_saved = true;
    echo $output;
}

if(!$bool_is_data_saved)
{
    echo ("Failed");
}

That code is... hard to read...

To me it seems cleaner to do the following instead of the foreach on the actual query:

$stmnt = $conn->prepare("SELECT * FROM table WHERE id=?");
$stmnt->execute(array($someId));
while ($result = $stmnt->fetch()){
    //do stuff
}

Also, breaking out of the PHP in the foreach to then turn around and echo inside the HTML is odd. Clean that up.

Lastly, in order to make this more manageable, I would use a couple of functions that you call from the HTML. Put the functions in the top of the doc.

To answer your question, I think the problem is that you do not define a select.

do this:

$output.='<td>';
$output .= '<select name="comboBox">';

foreach ($conn->query($stmt) as $res) {
    $output .= '<option value="'.$res['Status_ID'] .'">'.$res['Status_Name'],'</option>';
}
$output .= '</select>';
$output .= '</td>';

One more thing! You are using $stmnt variable in two different places for two different queries. either use a different variable or put your queries in functions.
