Is this possible ? Two or more product listing layouts (one per category)?

I installed the excellent mod -column_layout_grid_v_1_3_8- and this work very good for me. Thanks fo the awesome job.

Now i have a question. I have a new category, and for that category i want to use a different layout style for the product listing.
For the whole shop >> the colums option (products in 3 columns per row) and for my new category i want each product in its own row. How can i achieve this ?

I noticed that the mod overrides just two files in zencart's system.
Is there a way to use a specific tpl_modules_product_listing.php for my new category ?

Anybody has any idea?

Apologies if this is answered in a previous thread. I've been searching for a while and can't find it.

It would take some customizing of product_listing.php, and probably tpl_modules_product_listing.php, but it would not be difficult.

There are a number of tests like
if (PRODUCT_LISTING_LAYOUT_STYLE == 'rows') {
and
if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns') {
and you could add a test for $_GET['cPath'] equaling the category you want different, to use the rows instead of columns code.

thank you gjh42 for your reply and help.
i will try this tomorrow.

i found also another thread with the same problem :
http://www.zen-cart.com/forum/showthread.php?t=48433.
Unfortunately the answer is not complete, but the thread is informative and helpfull.

There are a number of places in the product_listing.php module for the column mod where the code tests for whether the layout should be in rows or columns.
Assuming you have the overall cart set to display columns, and the product category that you want to use rows for has a category_id of XXX, you could change each of the

if (PRODUCT_LISTING_LAYOUT_STYLE == 'rows')

tests to be

if (PRODUCT_LISTING_LAYOUT_STYLE == 'rows' OR (int)$current_category_id == XXX)

and each of the

if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns')

tests to be

if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns' AND (int)$current_category_id != XXX)

Yeah, it's possibe and it's easy. Thanks for your help gih42 and bunyip.:clap::clap:
For the really dummies like me, follow the advices given by bunyip precisely, it's all you have to do.
You have just to make these changes in two files, tpl_modules_product_listing (your template folder) and product_listing (module folder).
In tpl_modules_product_listing you will find

else {// (PRODUCT_LISTING_LAYOUT_STYLE == 'rows')

Since this is commented, don't care about them and leave this untouched.
And of course, you must have the mod -column_layout_grid_v_1_3_8- installded.

This is what I did, worked like a charm if you want to select the product listing module you want to use:

$listing_module_loaded = false;
if(!$is_index_listing && $_GET['main_page'] == 'index' && !empty($cPath)){
    $category_array = explode('_', $cPath);
    $category_array = array_reverse($category_array);
    foreach ($category_array as $c){
        $listing_module_file = DIR_WS_MODULES . zen_get_module_directory("product_listing_c_$c.php");
        if(file_exists($listing_module_file)){
            include($listing_module_file);
            $listing_module_loaded = true;
            break;
        }
   }
}
if(!$listing_module_loaded)
    include(DIR_WS_MODULES . zen_get_module_directory(FILENAME_PRODUCT_LISTING));

It doesn't work for me I installed the contrib to have it in tabular/grid display, made the changes to products_listing.php and tpl_module_products_listing.php but :

1- now in the category that should be displayed by row, I have only on product showing up instead of 542.

2- My table header with the description of the fields disappeared...

Please, help?

Fixed the 1- point, I forgot to modify an if()

2- still not showing

and still interested in yellow1912 solution

Thanks

Yellow1912's code would work to select among a number of different product_listing files depending on the category. It requires making a new file with the layout code you want for each different case. It is the ultimate in flexibility, but overkill for switching between rows and columns in the Column Grid mod.

Sorry for all this messages,
Fixed 2- as well
Thanks

@gjh42:
Thank you for your reply, I didn't see it before.

So this code goes in the products_listing.php file in the module directory.

Then you create a file named products_listing_c_'category_id'.php for each category.

Am I correct?

The selection code can't go in the file that it is selecting. I would have to research to find the file that calls product_listing.php (or its alternate).
At any rate, you really don't need to do the extra work if you just want to switch between the "columns" and "rows" layout styles. That is best handled with bunyip's examples.

It sounds like you somehow messed up the edits; best to go back and get those right than to try to fix it with significantly more complex editing.

What file would you put this code in?

Thanks!

Hopefully I can revive this thread. Bunyip's solution seems straight forward and may be the quick fix, but I would prefer to implement the long term solution. Can anyone offer help regarding yellow1912 solution.

1. will this work for ZC 1.3.9h or is there a better solution
2. where does the code go
3. once I implement the code do I just add a layout column in my categories table and populate with "row", "grid", "xx", "xy", and so on or would the assignment need to be the actual .php file name for each layout.

If you want two layouts, a row and a grid style, bunyip's code is the best way to do it. It is simple and elegant and doesn't take extra code in the codebase.

If you want (say) two kinds of grid layout, or three different layouts, yellow1912's solution will allow total flexibility as long as you are willing to write all the code for your desired layouts.
It works by testing for the existence of a file matching the current category id, so there is nothing to do in database tables; just make custom listing module files for each custom category and the code will find and use them where appropriate. The standard listing file will be used for any category that doesn't have a custom one.

Bunyip's code worked fine for me when doing a single category, but I need to do around 100 categories.

I think yellow1912 is the way to go, but that will have to wait until my programming knowledge improves. Oh well, back to Bunyips code.

I have tried several variations of "OR" "||" etc with undesirable outcomes. It almost looks as if the result are both row & column/grid format in one. I'm using ZC1.3.9 with column grid addon and sorry the site is not live. The last code I used, which I think is the proper way, was

if (PRODUCT_LISTING_LAYOUT_STYLE == 'rows' OR (int) $current_category_id == 2260 || (int) $current_category_id == 104150)

and

if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns' AND (int) $current_category_id !== 2260 || (int) $current_category_id !== "104150")

My questions are:
1)What am I missing?
2)Is there a shorter way to do the or statement because I have about 100 categories to do this for?
3)Or with this many categories should I beg and plead for help to implement yellow1912 version?

Thanks

Anyone? Did I not provide enough info? I'm sure it's the simple fact that I didn't code the statement correctly due to my lack of programming knowledge.

Thanks

Update:
Part of the initial problem was that I had the category 104150 in qoutes :oops:

I've revised the code for product_listing.php to these lines
if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns' AND (int) $current_category_id !== 2260 || PRODUCT_LISTING_LAYOUT_STYLE == 'columns' AND (int) $current_category_id !== 104150) {

if (PRODUCT_LISTING_LAYOUT_STYLE == 'rows' OR (int) $current_category_id == 2260 || PRODUCT_LISTING_LAYOUT_STYLE == 'rows' OR (int) $current_category_id == 104150)

and I've revised the code for tpl_modules_product_listing.php to this line
if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns' AND (int) $current_category_id !== 2260 || PRODUCT_LISTING_LAYOUT_STYLE == 'columns' AND (int) $current_category_id !== 104150) {

When applying to only category 2260 (everything past the || deleted) it worked fine. Once I added the information past the || it worked fine for category 104150 but seemed to mess up category 2260. Category 2260 looked as though it was displaying both in row & grid format.

1. Any idea how I can fix this
2. This will be like a lot of code to paste if I have 100 categories to apply this two. Any other shortcuts out there?

Thanks

I tried the simple method...but I don't know what went wrong. I can't seem to find a problem. I use the column grid mod and I have the newest version of Zencart. It seems to work fine even though the mod is not meant for the version.

I changed both php files. the first one.
there is either (two instances)

 
  if (PRODUCT_LISTING_LAYOUT_STYLE == 'rows') OR $current_category_id == ^2$)

or (3 instances)

if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns') AND $current_category_id != ^2$)
    

in the other file there's just this.

 if (PRODUCT_LISTING_LAYOUT_STYLE == 'columns') AND $current_category_id != ^2$) {
  require($template->get_template_dir('tpl_columnar_display.php',DIR_WS_TEMPLATE, $current_page_base,'common'). '/tpl_columnar_display.php');
} else {// (PRODUCT_LISTING_LAYOUT_STYLE == 'rows')
  require($template->get_template_dir('tpl_tabular_display.php',DIR_WS_TEMPLATE, $current_page_base,'common'). '/tpl_tabular_display.php');
}

is something wrong with this? it shows me a blank listing...

what I need is actually to have all subcategories of category id 2 to have the listing.

(http://outcast.cz)

stsung, I'm not knowledgeable as to if ^2$ should imply all subcategories (would be interesting to know as I'm still trying to fix my issue), but have you tried to set your category to = 9

This might be a good test to see if it works. I bet you probably have the same issue as me in that you need to apply this to multiple categories. Sorry I can't help any more than the above suggestion.
