I have several drop down lists in a table, I am trying to retrive

  • 0

I have several drop down lists in a table, I am trying to retrive the value of the drop down list if its not 0.

I have a table of items each item has the drop down list. Below is how I create the drop down list, I give it the tableid as a name because this is a unique identifier for the particular product.

echo "<td><select name=". $row['goosedown_id'] .">
                <option value=''> 0 </option>
                <option>1</option>
                <option>2</option>
                <option>3</option>
                <option>4</option>
                <option>5</option>
                <option>6</option>
                <option>7</option>
                <option>8</option>
            </select>
        </td>";

Then once the form is submitted I am trying to just print any values i can… cause im not sure how to proceed… I do this like so.

$goosedown_id = check_input($_POST['goosedown_id']);
//..

goose down = $goosedown_id

I am hoping to be able to print out the associated values or calculate the price based off other items in the table i.e. price etc. but I am hoping someone can help me with trying to access the items that are no 0 first.

    Have a look at the following example:

    <!DOCTYPE html>
<head>
    <link href="loginmodule.css" rel="stylesheet" type="text/css" />
</head>
<body>
    <?php
    if (count($_POST)) {
        for ($i = 0; $i < $_POST["nr_rows"]; $i++) {
            echo "<h2>id=".$_POST["goosedown_id"][$i].", qty=".$_POST["qty"][$i]."</h2>\n";
        }
        die("<pre>".print_r($_POST, true)."</pre>\n");
    } else {
        // connect to the database
        $link = mysqli_init();

        // Adjust hostname, username, password and database name before use!
        $db = mysqli_real_connect($link, "localhost", "root", "", "test") or die(mysqli_connect_error());

        $SQL = "SELECT * FROM 5050goosedown ORDER BY price ASC";
        $result = mysqli_query($link, $SQL) or die(mysqli_error($link));

        $rows = array();
        for ($i = 1; $row = mysqli_fetch_assoc($result); $i++){
            $rows[] = array(
                'id'        => $row['goosedown_id'],
                'bgcolor'   => ($i % 2) ? '#F5F5F5' : '#E5E5E5',
                'name'      => htmlentities($row['name']),
                'size'      => ($row['width'] || $row['height']) ? $row['width'].'/'.$row['height'] : '',
                'fill'      => $row['normal_fill'].'/'.$row['our_fill'],
                'old_price' => $row['old_price'] ? $row['old_price'] : '',
                'price'     => $row['price']
            );
        }
    }
