PHP - Automatic Classing Of Current Page Nav Item For Css Manipulation

Hey guys!

I need your help with some issues.
Firstly, I have an own website with a database filled with products, and also a template page(template.php) for each product. Problem is that I don't know how to generate each product from the database in the template.php file using their id from the database. How can I do this?

Second problem, I got an own checkout and I don't know how to redirect the customer to a "thank you for buying" page after clicking "Finish Order". It sends the customer to a white page where it says: "Thanks for buying!".

Third and last thing, do you guys know where can I find a php checkout template to follow?

Thanks in advance for your answers!
Cheers!

I have a script that seems to work well to insert a bookmark into a users database when he/she is logged into the system but I am having a hard time figuring out how I would go about making a work-a-round for having an item selected before being logged in, and inserted after they have logged in or registered.

For example, I would like a user to be able to select an Item to add to bookmark whether that user is logged in/registered or not and if they are not, they would be greeted with a login/registration form and after successful login the add bookmark script would be initiated on the item previously selected.

What I've got this far:

Simple form to add bookmark:

<form name="bm_table" action="add_bms.php" method="post">
<input type="text" name="new_url" value="http://" />
<input type="submit" value="Add Bookmark"/>
</form>


Then I have the add bookmark script:

BEGIN php

$new_url = $_POST['new_url'];

try {
    check_valid_user();  //cannot get past this part since it ends the script....code below
    if (!filled_out($_POST)) {
      throw new Exception('Form not completely filled out.');
    }
    // check URL format
    if (strstr($new_url, 'http://') === false) {
       $new_url = 'http://'.$new_url;
    }

    // check URL is valid
    if (!(@fopen($new_url, 'r'))) {
      throw new Exception('Not a valid URL.');
    }

    // try to add bm
    add_bm($new_url);
    echo 'Bookmark added.';

    // get the bookmarks this user has saved
    if ($url_array = get_user_urls($_SESSION['valid_user'])) {
      display_user_urls($url_array);
    }
  }
  catch (Exception $e) {
    echo $e->getMessage();
  }

END php


Checking valid user - the portion I cannot get past in the above script:


function check_valid_user() {
// see if somebody is logged in and notify them if not
  if (isset($_SESSION['valid_user']))  {
      echo "Logged in as ".$_SESSION['valid_user'].".<br />";
  } else {
     // they are not logged in
     do_html_heading('Problem:');
     echo 'You are not logged in.<br />';
     do_html_url('login.php', 'Login');
     do_html_footer();
     exit;
  }
}



How would I go about modifying the script so that a user could fill in the form (later it would be a link...obviously they probably wouldn't be filling in a form that is log-in specific - but same concept I think)

Thanks in advance for the help!

is this possibe with php?

Hi there,

I think this is a big question but I'd appretiate any help you can provide!!
I have a list of items and subitems in a table that looks like this:

id    parent_id    title 1    0    House Chores 2    1    Take Out Trash 3    1    Clean Room 4    0    Grocery List 5    4    Eggs 6    4    Produce 7    6    Lettuce 8    6    Tomato 9    4    Milk
I want to display it like this:

(+) House Chores:
       > Take Out Trash
       > Clean Room

(+) Grocery List:
       > Eggs
       (+) Produce
            > Letutce
           > Tomato
       > Milk

 
So basically each entry in the table has an unique id and also a parent id if it's nested inside another item.
I "sort of" got it figured out in one way, but it doesnt really allow for nested subgroups. I'd like to know how would y'all PHP freaks to this

Also taking suggestions for the javascript code to expand/collapse the tree !!

Thank you!

Why this code dont work :S
<?php
    echo '
    <ul>
        <li'; if ($_SERVER['PHP_SELF'] == "kategorije.php") { echo ' id="current"'; } echo '><a href="kategorije.php"><span>Kategorije</span></a></li>
    </ul>';
?>


Checking if PHP_SELF is "kategorije.php" do not work, why, and what is solution ?
