Getting ComboBox variable to store in MySQL
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 );
}
}
}
?>

Any help on how I can do it?
Screenshot to get a basic idea of what I'm doing:
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 $row['emp_number']; ?>']">
<option value='all'>All</option>
<option value='remote'>Remote Gaming</option>
<option value='landbased'>Landbased Gaming</option>
<option value='general'>General Gaming</option>
</select></td>
</tr>
<?php
}
Then, on your target_url.php, you will have to do:
If
target_url.phpis the same as your form, then code below should be placed at the very top of your document.
<?php
if( isset($_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.
i suggest:
- Use require_once( "db_connect.php" ) <- in this file make connection
- Use smarty & html_options to show this drop down.
1 time your will learn this, next - using. Code will start be organized ... Maybe to complex for starter. But this is right Way.
