cutting product descriptions manually (for listings)

Okay there's this super handy function in wordpress which strips blog posts on the frontpage, whenever it runs in to <-- more --> command (or something similar)

Anyway could we make similar thing to zen?

Basic idea is that we'd add manually some command in the description from the admin and it would strip the product description in product listing pages instead of constant number of characters.

is there a better way (aka simpler method to our html illiterate people) to make this happen besides using hidden css class in the listing pages?

actually somehow the product listing page doesn't display html at all in the product description?!? so even I'd wrap the text I'd want to leave out into a div it won't display the div at all..

any idea how to fix this? I'm using grid (column) mod

See the Customizing Product Description Text Formatting on Category Page thread for a method with minimal coding to make different descriptions on listing and info pages, including enabling HTML in listing pages.

If you only want to choose the point to truncate the description on the listing page, I believe this would work (not tested yet):

In /includes/modules/your_template/product_listing.php, find this

PHP Code:

---

        case 'PRODUCT_LIST_NAME':
        $lc_align = '';
        if (isset($_GET['manufacturers_id'])) {
          $lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . zen_trunc_string(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))), PRODUCT_LIST_DESCRIPTION) . '</div>' ;
        } else {
          $lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), ($_GET['cPath'] > 0 ? 'cPath=' . $_GET['cPath'] . '&' : '') . 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . zen_trunc_string(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))), PRODUCT_LIST_DESCRIPTION) . '</div>';
        }
        break;

and beginning at "zen_trunc_string" change to this

PHP Code:

---

        case 'PRODUCT_LIST_NAME':
        $lc_align = '';
        if (isset($_GET['manufacturers_id'])) {
          $lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . str_replace(strstr(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id'])),"*more*")),"",(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))))) . '</div>' ;
        } else {
          $lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), ($_GET['cPath'] > 0 ? 'cPath=' . $_GET['cPath'] . '&' : '') . 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . str_replace(strstr(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id'])),"*more*")),"",(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))))) . '</div>';
        }
        break;

This will delete everything after *more* inclusive. It will not truncate the description to the set length if there is no *more*. That could be re-added to the code if desired (making it still more complex!)

You would then need to remove the *more* from the description in the info page.
FInd this

PHP Code:

---

 <!--bof Product description -->
<?php if ($products_description != '') { ?>
<div id="productDescription" class="productGeneral biggerText"><?php echo stripslashes($products_description); ?></div>
<?php } ?>
<!--eof Product description -->

---

and change to this

PHP Code:

---

 <!--bof Product description -->
<?php if ($products_description != '') { ?>
<div id="productDescription" class="productGeneral biggerText"><?php echo str_replace("*more*","",stripslashes($products_description)); ?></div>
<?php } ?>
<!--eof Product description -->

ah wonderful many thanks again G

Actually I didnt have time to testi this until yet. I tried the *more* thing but first of all it didn't cut it and second

Warning: Wrong parameter count for strstr() in /home/public_html/store/includes/modules/classic/product_listing.php on line 154

Any idea? appreciate your help a lot though. many thanks

OK... I think there is a misplaced close parenthesis in the code. There should be three before the "*more*" and one after, not two and two.

PHP Code:

---

        case 'PRODUCT_LIST_NAME':
        $lc_align = '';
        if (isset($_GET['manufacturers_id'])) {
          $lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . str_replace(strstr(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))),"*more*"),"",(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))))) . '</div>' ;
        } else {
          $lc_text = '<h3 class="itemTitle"><a href="' . zen_href_link(zen_get_info_page($listing->fields['products_id']), ($_GET['cPath'] > 0 ? 'cPath=' . $_GET['cPath'] . '&' : '') . 'products_id=' . $listing->fields['products_id']) . '">' . $listing->fields['products_name'] . '</a></h3><div class="listingDescription">' . str_replace(strstr(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))),"*more*"),"",(zen_clean_html(stripslashes(zen_get_products_description($listing->fields['products_id'], $_SESSION['languages_id']))))) . '</div>';
        }
        break;

Hopefully my bleary eyes are seeing this right. Try it and let me know how it works.

works like a charm. many many thanks!

an another thing is can this be used for the new listing as well? I tried but really couldn't make sense from the new_listing file since the structure is different

and apparently new listing page strips all html from description? so I couldn't use div to hide the rest. if *more* can not be applied how can I remove html block?

All of the listing pages strip HTML from the description, and currently each of them has its own file so each one will have to be edited to change this. Search on zen_clean_html and you should find a description of the process - very simple.

The *more* code should be applicable to all of the listing pages, but as mentioned the files are different so it will take some rooting around to be sure of the right edit location.

The centerboxes are very different, and may not include the description at all, so they would be much more involved to modify.

thanks gjh actually figured out everything else but I'm still struggling how to remove *more* text from the new listing. I decided to go with the html so It wont need to cut it but I'd still like to hide the *more* text?

This is adding another layer of code, but you could wrap the *more* tags in

<span class="moreMarker">*more*</span>

and style

#newProductsDefault .moreMarker {display: none;}

I thought about it but doesn't it leave open span class to listing pages where more cuts the description.. oh well I don't think it will do any harm though

Hmm that's right... You could get a little trickier with the cutting and trim the string another 26 characters if it trims at a *more*...

I have the feeling we're running into duplication of effort. Are you really using the div hiding for some listings and the *more* truncating for others?
If you tell me the exact file that applies to the listing you are working on (there are near-duplicates that work on similar-sounding but different places), I will look at it and find the right place to apply the *more* truncating.

no everything seems to work perfect for me now. MANY MANY thanks for your effort. Actually I use the span class with *more*, and applied all html stripping to that specific list so the span tag gets cut. New listing is html but parts of it hidden with css and the product page displays the whole listing.. I think you should make a mod from this since I could imagine lots of people could find it useful. Anyway many thanks again.

I changed files /tpl_docs_general_info_display.php, and /tpl_docs_product_info.php, and also modified /product_listing.php, all as in post 454486 and corrected the minor error of ) placments according to subsqquent post.

In addition, I stripped the zen_clean_html. And then to my lisitings I added the *more*

This has nicely cleaned up my listing pages, html in tact, but I still have the *more* showing on the product pages.

I put

<span class="moreMarker">*more*</span>

in place of *more* in a few product descriptions to test it, and I added

#newProductsDefault .moreMarker {display: none;} to my style sheet

With no effect - the *more* still shows on the product pages. Did I make these edits in the wrong files?

Just wanted to post a thanks for the code in message #6. Although written a while back now, it just untangled a huge problem for me.
