Question

I have a simple DB and a small table in it. This table named STOCK has only one column – names of different items in a stationery.

I am dynamically generating a form in PHP-MySQL which fetches Item from STOCK (such as Pencil, Pen etc.) and displays them by using echo() function. So I have generated a form which displays Item and correspondingly an <input> text box. Upon submitting this form, how can I access all the Names and their text inputs by traversing through the $_GET array?

The dynamically generated form is:

        $res = mysql_query("SELECT * FROM Stock");

        echo "<form name='input' action='add_stock_later.php' method='get'>";
        echo "<table align='left' border='1'>
        <tr>
        <th>Item</th>
        <th>Quantity</th>
        <th>Remarks</>
        </tr>";

        while($row = mysql_fetch_array($res))
          {
            $item = $row['Item'];
            echo "<tr>";
            echo "<td>" . $item . "</td>";

            echo "<td><input type='text' name='$item'></td>";
            echo "<td><input type='text' name='Remarks'></td>";
            echo "</tr>";
          }

          echo "<tr><td></td>
        <td align='middle'><input type='submit' value='Submit'></td></tr>";


        echo "</table>";

Now in the add_stock_later.php, how can I access all these $item and it’s corresponding input without having to manually do it using $_GET['Pencil'], $_GET['Pen'] and so on.

First edit your form.

echo "<td><input type='text' name='".$item."[quantity]'></td>";
echo "<td><input type='text' name='".$item."[remarks]'></td>";

Then use foreach().

foreach ($_GET as $stationery => $info) {
    $stationery; // name of the stationery
    $info["quantity"]; // quantity of the stationery
    $info["remarks"]; // remarks for the stationery
}
