Looking To Save And Recall Dropdown Values

[gummby8]

I am trying to create a dropdown box and save its selected value to SQL (this part I can do so far)

 

But what I would like is to be able to use the URL of the same page to pull saved data back

 

So if I saved project ID#1 the URL would be

 

www.project.com/form.php?ID=1

 

Now I know how to get the ID and reference all the SQL data already.

 

How do I get all the dropdowns to populate with their saved values from SQL? Or should this have gone in the php forums?

 

Thank you.

Are you simply trying to make the values pre-selected in the fields?

Yeah pretty much

Assuming $db['value'] is the value in the database, and you're building the list of <option>s dynamically from an array similar to the one below, the logic would look like this. If your list of <option> tags is static, you'll need to add the comparison to each one of them.

 

echo "<select name=\"select_field\">\n";
$options = array( 1 => 'one', 2 => 'two', 3 => 'three', 4 => 'four' );
foreach( $options as $k => $v ) {
    $selected = $k == $db['value'] ? 'selected="selected"' : '';
    echo "<option value=\"$k\" $selected>$v</option>\n";
}
echo "</select>";

to be able to populate it you need to include selected="selected" in option value

 

example below

 

 <?php
 $SQL = "" // some line of SQL codes.
   $years=date('Y');

  echo '<option value='.$rowid[years].' selected="selected">'.$rowid[years].'</option>';
   for ($i=$years;$i>=2000;$i--) {
  echo '<option value='.$i.'>'.$i.'</option>'; 
   }
   ?>
	  </select>

The code I posted adds selected="selected" to the options without listing them out of order, or double listing them.
