Hi,
I’m currently using eStore 6.9.0.2 and NextGen 1.9.6 with the single product integration method and have two queries regarding the download functionality.
Firstly, is it possible to use the eStore_perform_save_as_file_name_massaging() function to provide a more secure, unique download URL to each customer? For example if
$file_name = $file_name.".jpg";was rewritten as$file_name = "download_" . uniqid() .".jpg";Are there any issues with this approach?
Secondly, if you have a variations list on the product like “Download:5.00|Print 3×4:10.00|Print 7×8: 12.00” is it possible to only provide a download link if the first variation is selected?
Yes, the teak you intend to apply looks correct.
No, the download with variation won’t work like that. It usually works like that when you use the “Digital Variation” option of eStore but this method of NextGen Gallery integration doesn’t have that option as the image file gets served from NextGen gallery plugin.
Would it not be possible for me to add a check on which variation has been selected when the confirmation email is sent out, and strip the URL and download information there? If it is, could you point me in the right direction for which files to look at?
Okay. There is a filter that eStore applies on the outgoing email body. If you are familiar with WordPress filters then you could write a small plugin to dynamically change the email body of each sale before it is sent out. If not, look for the following line of code in “paypal.php” file:
$body = apply_filters('eStore_notification_email_body_filter', $body, $this->ipn_data, $cart_items);Change the email body however you wish just before or after the above mentioned line.
That information is not available there in a *selectable* way. You would have to look at the *email body* and see how you can use regex to select it and then modify it how you want. It won’t be straightforward… this is why my first response to you was that this option is not available.
I would recommend you to do a PayPal checkout, that way you will get the exact expected behavior since you are using PayPal for your checkout option.
Unfortunately you can’t pay yourself with PayPal and eStore doesn’t seem to support the PayPal Developer Sandbox for testing. Can I not just modify paypal.php to skip over the actual payment process and jump to the order email?
Sorry, my mistake, I didn’t realise the sandbox mode was on the General Settings rather than Payment Gateways.
In case anyone is wondering how to do this in the future, here are my modifications to paypal.php. Remember to mark your changes with comments so they are easy to find and reapply when upgrading eStore in the future
After
var $sandbox_mode = false;on line 26 add://Hephaestus - 01/11/2012var $download_variation; // only provide a download link for products with this variation
Find this code block around line 400:
//Generate link from Nextgen gallery if PID is present.if(!empty($pictureID))
{
$download_link = eStore_get_ngg_image_url($pictureID,$cart_item_data_name);
$pictureID = "";
}
else
{
$download_link = generate_download_link($retrieved_product,$cart_item_data_name,$this->ipn_data);
}
$this->debug_log('Download Link : '.$download_link,true);
Replace this with:
//rbearman - 01/11/2012 - START//Don't provide a download link if the variation is not as specified in $download_variation
if(strpos($cart_item_data_name, '('.$this->download_variation.')') !== false)
{
//Generate link from Nextgen gallery if PID is present.
if(!empty($pictureID))
{
$download_link = eStore_get_ngg_image_url($pictureID,$cart_item_data_name);
$pictureID = "";
}
else
{
$download_link = generate_download_link($retrieved_product,$cart_item_data_name,$this->ipn_data);
}
}
else
{
$download_link = "";
}
$this->debug_log('Download Link : '.$download_link,true);
//rbearman - 01/11/2012 - END
