View Full Version : Help passing variables between templates..

I've been searching for a bit but have not come across anything that really matches my dilemma.

My code probably isn't the greatest as I am learning as I go, please be kind..

Here is where my issue begins, I can read data from my database and pass it to the template to be displayed within a table
$query = "SELECT * FROM BAMFG_vehicle";
$result = mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_array($result)){
$output .= "<tr><td width=100>".$row['year']."</td><td width=100>".$row['make_model']."</td><td width=20>".$row['vehicle_id']."</td><td width=100><a href='bamfg_vehicle.php?do=delete_vehicle&id=".$row['vehicle_id']."'>DELETE</a></td><td width=100><a href='bamfg_vehicle.php?do=edit_vehicle&id=".$row['vehicle_id']."'>EDIT</a></td></tr>";
}

$templater = vB_Template::create('BAMFG_vehicle');
$templater->register('navbar', $navbar);
$templater->register('output', $output);
print_output($templater->render());

When the template is displayed, the table looks good and the links work well with the URL being listed as:
http://emycrosoft.com/BAMFG/bamfg_vehicle.php?do=delete_vehicle&id=42
when I click 'DELETE' on vehicle id 42, or whichever other vehicle I click on appears in the url respectively.

What I'm needing to do is pass the vehicle_id variable from the above code to:
if($_REQUEST['do'] == 'delete_vehicle') {
echo "HOLY CRAP - DELETING VEHICLE";



echo $id;

$templater = vB_Template::create('BAMFG_delete');

$templater->register_page_templates();
$templater->register('navbar', $navbar);
$templater->register('vehicle_id', $vehicle_id);
print_output($templater->render());}


I need the variable passed so I can do another query to pull the rest of the data from the table based upon the vehicle_id for a pop up confirmation I will be working on.

Should I rework the output from the original query to have the links rendered within the template so I an use the $POST command to resubmit the data? and if so, how? I'm currently googling my brains out looking for help!

So, in a nutshell this is the beginning and I've been putting this together through examples and tutorials I've found. I was hoping to get it working then go back through and 'streamline' and get rid of all that is not needed.

Thanks guys..

You don't have to change it to POST, just do something like this:

if($_REQUEST['do'] == 'delete_vehicle') {
echo "HOLY CRAP - DELETING VEHICLE";

$vbulletin->input->clean_gpc('r', 'id', TYPE_INT);
$id = $vbulletin->GPC['id'];


...and then next you'll probably want to make sure $id is actually set to a valid id, or at least is an integer >= the min id.
