Getting ComboBox variable to store in MySQL_问答_开发者

I have an html page that gets data from 'hs_hr_employee' table and lays the info in a table on a web page. Then I have another table 'rights' which gets info from 4 columns from the 'hs_hr_employee' table and stores them in columns. In addition to those 4, the 'rights' table has an extra column 'Permissions'.

Now, I have a combobox with 4 options. When I click the 'Save' button I want to store the value select in the combobox and save it in the 'rights' table in relation to the user.

(Each user has a combobox next to it).

Updated code:

       <?php

 $connection = mysql_connect('localhost','admin','root');
if( isset($_POST['submit']) )
{
    if( isset( $_POST['cb_permissions'] ) && is_array( $_POST['cb_permissions'] ))
    {
        foreach( $_POST['cb_permissions']  as $emp_number => $permission)
        {
            $sql = "UPDATE `your_permission_table` SET permission='".mysql_real_escape_string($permission)."' WHERE emp_number='".mysql_real_escape_string($emp_number)."'";
            echo __LINE__.": sql: {$sql}\n";
            mysql_query( $sql );
        }
    }
}
?>

          }

        mysql_select_db('users', $connection);

        $result = mysql_query("SELECT emp_number, employee_id, emp_lastname, emp_firstname  FROM hs_hr_employee");

        echo "<center>";

        echo "<table >

Any help on how I can do it?

Screenshot to get a basic idea of what I'm doing:

Getting ComboBox variable to store in MySQL

First of all, you should move connection code at the very top of your documents:

$connection = mysql_connect('localhost','admin','root'); 
if (!$connection)
{
    die('Could not connect: ' . mysql_error());
}

mysql_select_db('users', $connection);

Next, you have to wrap your table inside tag:

<form method="post" action="target_url.php>
    <table>
    ...
    </table>
    <input type="submit" name="submit" value="Save"/>
</form>

After that, you would store employee_id or emp_number (depending on what table key you will use for setting permission) somewhere on your form:

while($row = mysql_fetch_array($result))
{
?>
<tr>
    <td><?php echo $row['emp_number']; ?></td>
    <td><?php echo $row['employee_id']; ?></td>
    <td><?php echo $row['emp_lastname']; ?></td>
    <td><?php echo $row['emp_firstname']; ?></td>
    <td><select name="cb_permissions['<?php echo $row['emp_number']; ?>']">
        <option value='all'>All</option>
        <option value='remote'>Remote Gaming</option>
        <option value='landbased'>Landbased Gaming</option>
        <option value='general'>General Gaming</option>
    </select></td>
</tr>
<?php
}

Then, on your target_url.php, you will have to do:

If target_url.php is the same as your form, then code below should be placed at the very top of your document.

<?php
if( isset($_POST['submit']) )
{
    if( isset( $_POST['cb_permissions'] ) && is_array( $_POST['cb_permissions'] ))
    {
        foreach( $_POST['cb_permissions']  as $emp_number => $permission)
        {
            $sql = "UPDATE `your_permission_table` SET permission='".mysql_real_escape_string($permission)."' WHERE emp_number='".mysql_real_escape_string($emp_number)."'";
            echo __LINE__.": sql: {$sql}\n";
            mysql_query( $sql );
        }
    }
}
?>

That's it.
