如何从mysql-db中选择正确的选择/选项

Question

I have a edit page where I can edit the status of a message.

<select name='cm_status'>
option value='Open'>Open</option>
<option value='Closed'>Closed</option>
</select>

Then I change the status to closed, but when i go into the page again, the open is selected even when the status is set to closed, and I wonder how to get the closed one selected.

Thanks in advance,

Kristian

You will need to query the database when the page loads and create the form after evaluating the results.

You will set the attribute selected=selected on the option value depending on the value received from the database.

Here is a simple version of what you will need:

$query = mysql_query("SELECT cm_status FROM some_table");
$row = mysql_fetch_array($query)
echo "<select name='cm_status'>";
if($row == "Open")
echo "<option value='Open' selected>Open</option><option value='Closed'>Closed</option>";
else
echo "<option value='Open'>Open</option><option value='Closed' selected>Closed</option>";
echo "</select>"

This form will need a form handling PHP script that will update your MySQL database table using $sql="UPDATE mytable SET mycolumn = 1 WHERE mytable_id = 1";
