[RELEASED] Product Downloads PRO (vQmod)

Batch add multiple downloads * Tag download files * Make files freely downloadable *

With this modification you can make OpenCart downloads free, so they can be downloaded from the product page without making a purchase - so called free downloads as product extras. Ideal for adding product manuals, datasheets, brochures, drivers etc to your main product which need to be freely accessible. You can also see & display & reset the total number of times a file has been downloaded.

The mod also adds a separate tagging system enabling you to tag your downloads with custom labels. Tags are used for filtering the free downloads. This is especially useful if you have lots of free downloads associated with products. You can make tags "administrative" so they will not be visible in the store front, but they can still be used in the admin panel for tagging and filtering.

Additional feature that the mod comes with is batch insertion of download files to OpenCart. This way you can upload multiple files with FTP and have them added with just one click. This is especially useful for adding lots of files or files which are larger than PHP maximum file upload size limit.
The mod gives you two options: Auto Add and Directory Add. First one is useful for single click insertion of downloads from a single specified folder on the server. The second, Directory Add, opens up a separate form that enables you to choose from which subfolder (inside a specified root folder) the files will be added. Files can be recursively searched and filtered by file type. You can set tags that will be added to all the inserted files. You can also auto tag the files by enabling path-to-tags feature, which will translate file path to tags, such that each folder is a separate tag.

In the admin panel you can associate downloadable files with the product as usual. Only files marked as "free" will show up on product page (in store front) and can be downloaded from there. You can mark products as "free" in the Downloads section (Catalog -> Downloads -> Downloads). On the same page you can add multiple files from a directory to the OpenCart download system with just one click. You can add/edit/delete download tags from Catalog -> Downloads -> Download Tags).

On the product view page a new tab or module (depending on the settings) will appear which contains the downloadable material.

One quick question, can this mod be used to sequentially make available a single file per product purchased, after someone makes a purchase? Sequential files, stored in specific folders, one folder associated to one product.
I need to make this work somehow... sequentially allocate the files, one by one, after customers purchased the specific product(s). Disabling the files sequentially, so they won't be associated to the next purchase of product X (same product)
Yes, I want to sell services basically, and the downloadable files will be the end-product purchased by the customer.

No, this kind of behaviour cannot be achieved with this mod.

Hmm... was trying to avoid buying this expensive module... http://www.opencart.com/index.php?route ... order=DESC

But none the less, If I'll go that route with the serials, I will have to buy your module to maybe include a nice template per every product, containing a nice presentation and detailed instructions. Will see, next week I'll have a budget meeting and will purchase via the shop if approved.

Thank you
Have a nice day!

Released version 2.0.0 - a lot of code refactoring with a few bug fixes and several new features. This adds an option to display downloads without download link if login is required - this can be configured per download or gloablly for all downloads. It also adds downloads filtering to the admin area and introduces download status - enabled/disabled.

Before and after update i still get this error when saving download options..

Notice: Undefined variable: tags in /home/##mysite##/public_html/vqmod/vqcache/vq2-admin_controller_catalog_download.php on line 155Warning: array_unique() expects parameter 1 to be array, null given in /home/##mysite##/public_html/vqmod/vqcache/vq2-admin_controller_catalog_download.php on line 155Warning: Invalid argument supplied for foreach() in /home/##mysite##/public_html/vqmod/vqcache/vq2-admin_model_catalog_download.php on line 82Warning: Cannot modify header information - headers already sent by (output started at /home/##mysite##/public_html/admin/index.php:96) in /home/##mysite##/public_html/vqmod/vqcache/vq2-system_engine_controller.php on line 28Warning: Cannot modify header information - headers already sent by (output started at /home/##mysite##/public_html/admin/index.php:96) in /home/##mysite##/public_html/vqmod/vqcache/vq2-system_engine_controller.php on line 29

ps I renamed to ##mysite##

Please clear vqmod cache and see if/what error message is then produced.

Same error.. is tags a database field ?

Please re-download the module from OpenCart extension store and replace all files + clear all vQmod cache files.

Notice: Error: Unknown column 'login' in 'field list'
Error No: 1054
UPDATE download SET remaining = '9999', is_free = '1', file_size = '714520', login = '0', status = '1' WHERE download_id = '3' in /home/#####/public_html/system/database/mysql.php on line 49

Can you send me the field details and ill add it to the database..

Found and fixed it, some reason it didnt change the database..

Did you uninstall the previous version before you upgraded to the new version?
When upgrading you should uninstall the old version, then replace the files and install again. This way all new database changes will be made automatically.

Previous version, didnt make the database changes .. changed manually seems fine

Currently no, that information is not available.
