Simple Category Tree

[some name not taken]

What are you trying to do?

Define session, then call on session with $content by the looks of things.

So I have now changed the code as follows

<?php
$_SESSION['category_tree']->build_deepest_level_children(), retrieve_cpath();
$content .= $_SESSION['category_tree']->build_category_string('ul', 'li', '', 0, 2);
?>

...but this, too, is not correct.

Define session, then call on session with $content by the looks of things.

--> Can you explain?

And the code you posted is wrong by the way, what are you trying to do with retrieve_cpath()?

I am just trying to make the tree display as follows:

category1
subcategory1
product1
category2
subcategory2
product2

etc.

If $session needs to define all that is then called on by $content to build the desired tree it is logical to assume that all that needs to be defined, except the layout parameters (which appear to be handled by $content), needs to be defined in the $session, so I need to work out some way of entering more definitions into the $session line or some way of being able to call on multiple $session variables in the $content line.

Note:
This tree does not contain product, you will have to modify it if you want it to do what you want.

I think you may need to read more about php regarding:
1. Class and methods
2. Session

You will also need to know that $content is simply a normal variable, it just happens that the way Zen sidebox works is: you stuff all the content of the sidebox into this variable, and Zen will print it out for you.

You can always do something like

$content = '';

$content .= 'first line<br />';
$content .= 'second line<br />';

Yes, I do need to update my knowledge of PHP, but practical usually works best for me and once I have the outline I will quickly develop my skills where Zen Cart is concerned.

I now have the following (working) code...

...but still not to products level

<?php
$content = '';
$content .= $_SESSION['category_tree']->build_category_string('ul', 'li', '', 0, 2);
$content .= $_SESSION['category_tree']->build_deepest_level_children();
$content .= $_SESSION['category_tree']->retrieve_categories_tree_array();
?>

I guess that when you said about adding products myself you were meaning that the tree does not contain that kind of functionality, so I would have to expand on the existing code and effectively build a new module? ...and the simple_category_tree and all_subcat_produts can only give you tree levels down to subcategory only?

[yellow1912]

Yes, the tree does not go to product level, you will have to add that if you want to, basically it's not so hard, just traverse the tree and query products id then attach them there.
This type of functionality is not planned for this module in any near future, but you can add if you want to.

There is a module in the download that returns a tree with product level, however.

modules -> pages -> index -> header_php.php?

OK, thanks, but as the files from all_subcats_products basically overwrote the existing files for simple_category_tree that should mean that the line

$_SESSION['category_tree']->build_deepest_level_children();

will retrieve things on a product level, otherwise this line effectively does nothing.

[some name not taken]

The code still won't display subcategories...

$_SESSION['category_tree']->build_deepest_level_children() 

...simple, yes, but still not working.

Full code

<?php
$content = '';
$content .= $_SESSION['category_tree']->build_category_string('ul', 'li', '', 0, 2);
$content .= $_SESSION['category_tree']->build_deepest_level_children();
$content .= $_SESSION['category_tree']->retrieve_cpath()
?>

Right, I've added a 'li' value to accomodate the subcategory line, but cannot get the subcategory to display - I just get li showing where the subcategory should be.

(The first number in the brackets indicates the category ID, so a value of 0 shows all category IDs, but 1 would only show category 1, 2 for category 2 only, etc. whilst the second number controls the subcategories... if you can get them to display, that is).

So, it looks like even with the correct syntax subcategories, like actual products, cannot be displayed either ...and certainly not in any kind of unordered list.

Well, it would have been useful to know that several hours ago.

Thanks for your time and help anyway, Yellow.
