dropdown session

[gokeeffe]

Slainte,

Could someone help me the the following question.

I have a dropdown list which is pulling from a mysql

database.

What i want to do is keep the item that is selected in the

dropdown visible to the user if they navigate back to check

their inputs. I am using sessions but cannot figure out to

apply them to the code for dropdowns

Here's my code

----------------------------------------------------------------------------------------------------------------------

echo "<option value=\"$row[0]\">$row[1]</option>\n";

----------------------------------------------------------------------------------------------------------------------

Hence I want to make $row[1] a session variable to that it

stays visible until the form is submitted.

Here's the entire code so that it makes more sense

----------------------------------------------------------------------------------------------------------------------

echo'<tr>
<td colspan="2" class="labelcell"><label for="junior_subject_id">Select Subject:</label></td>';

echo'<td colspan="2" class="fieldcell2"><select name="junior_subject_id">';

$query_result = mysql_query ('SELECT * FROM junior_subjects ORDER BY junior_subject_id');

while ($row = mysql_fetch_array ($query_result, MYSQL_NUM))

{
echo "<option value=\"$row[0]\">$row[1]</option>\n";
}

echo'</select></td>';

echo'</tr>';

----------------------------------------------------------------------------------------------------------------------

Tks in advance i know you guys can help

You might want to try putting this line at the top of your php:

header("Cache-control: private");

OK but what will that do will i not still have to register

the array $row[1] as a session

session_start(); at the top, then you need to assign the variables to a session variable or two.

$_SESSION['foo'] = $row['bar'];

You can then use:
if(!($_SESSION['foo'])) {
//session is not set
}
else {
// session is set
}
