Allowing your customers to comment on products you offer for purchase can increase their sales rate. Positive comments left by visitors will help undecided visitors with their purchasing decisions. Unwanted comments and spam, can be a problem, so you will want to be able to moderate the comments. The Product Comments module allows your visitors to leave comments and you or a store employee to moderate them for undesireable posts. Below are the steps for installing and configuring the Product Comments module in your PrestaShop 1.5 store.

How to install and configure the Product Comments module in PrestaShop 1.5

  1. Log into your PrestaShop 1.5 dashboard.
  2. Using the top menu bar, hover over the Modules tab and select the Modules option.
  3. From the Modules list screen, scroll down until you find the module named Product Comments. Click on the Install button located to the right of the module's row.
  4. Once installed, you will see a successful installation message on the screen. From here click the link entitled Configure to continue to the module configuration screen.
  5. You are now on the settings configuration screen for the module. This screen is divided up into five sections. Some of them have configurable settings.

    The Configuration section is the first and has the general settings for the module. This section is the only one with a Save button that must be clicked to activate the settings.
    All comments must be validated by an employee Whether you want the guest comments to post immediately, or whether they need to be viewed by an employee first.
    Allow guest comments Whether to allow comments by guests, or members only.
    Minimum time between 2 comments from the same user The amount of time a user must wait to post again. This can prevent bots or even spam by overcommenting.

    Next up is the Moderate Comments section. This area displays any comments that need to be reviewed before they are posted.

    The third section is the Reported Comment section. This is for any comment that is reported by another user for being offensive.

    Fourth is the Add a New Comment Criterion section. This is for you to guide the commentors in their responses. For example, the default criterion is Quality.

    Last, there is the Manage Comment section, where you will see all comments, even after they have been approved in the moderated section.

    Congratulations! You have configured your Product Comments module. You can always return here to moderate any comments that need it. Below is a screenshot of how the comment appears in the front end of the store.

Is there any way to be notified when a review is waiting for approval? We have a small, not very busy webshop so checking for comments every day is not not something we do.

You should receive notification at the primary email address you have set for admin account. Do you receive any notifications? Which version of Prestashop are you using?

Hi we are using prestashop and the module will only appear beneath the Out Of Stock products with a star rating and ammount of reviews. How do we attach (or Hook) this to products that are currently in stock also?

Hello Chris,

It should work for all products assuming everything is set up correctly. What version of PrestaShop are you using? Is the module version compatible with that PrestaShop version? Is there any error message that occurs? Have you enabled PrestaShop error reporting to see if any other issue is occurring? Does it occur in multiple instances of the site?

Kindest Regards,
Scott M

Hello Daniel,

Thank you for contacting us. Since I could not find a built-in way to accomplish this you will have to develop a solution, or use a 3rd party plugin.

Here is a link to a possible solution I found in the official PrestaShop forums titled Product comments default as 5 stars instead?.

Thank you,

I am using prestashop and Product Comments v3.5.0 .

But Product Comments is not working on my live website.

When we check same module "Product Comments" with same "Pretshop" version on my local machine, it is working fine.

When i enable debug mode, i got following error

"Notice: Trying to get property of non-object in /var/www/html/classes/controller/FrontController.php on line 291 Fatal error: Call to a member function isLogged() on null in /var/www/html/classes/controller/FrontController.php on line 457"

Is it possible to hide the module/comments option for selected products?

Thanks for your help.

Hello Chrome,

Do you mean the "Moderate Comments" section? That will simply show a message if there are none to moderate but cannot be removed to my knowledge.

I am using the Product Comment Module v 3.4.1 with my website with the version of Prestashop

The problem for me is that when somebody wants to leave a comment, the quality doesn't function well, the numbers don't change them in bold when someone click on it. So the users don't know if they chose any quality.

 Can you help me ?

Thank you,

Hello Theo,

Thank you for contacting us. I recommend enabling error reporting in PrestaShop. This allows you to see the specific error messages on the screen, if any are being generated. From there, you will then be able to troubleshoot further or reply with the full error message for additional help.

If no error messages are produced, please reply with this specific steps you are taking to see the problem. Since in my tests, I was unable to locate the Comment module.

Thank you,

Hi JeffMa

thank you for your suggestion, sorry but I have no idea for the theme, my friend helped me to make a personalised theme with a very simple template, but don't know what it's called.

We have a tutorial on changing your PrestaShop theme in which you could change to another theme to see if the issue still exists, and change it back at a later time to see if the issue still exists on a different theme.

Hi JeffMa, thank you very much, will go and follow your link, but my initial reaction is to scream with horror !! (lol) because this website is my living = bread and butter, I have no other means of income and changing the theme (or anything else for that matter) really frightens the heck out of me. I am going to ask somebody who understands prestashop better to help me with this. I think it's out of my league. Great resource of information you have here :)

Hello Nia,

Sorry to hear about your problem with the product comments module. I set it up and tested it myself and it works with no issues. I tested with a registered user and guest user and both were able to use comments. There are several settings within the module that may affect the comments that are shown. Can you tell me what version of PrestaShop you're using? And also, what version of of the module that you have installed? Are you using any particular themes? We need a little more information so that we can investigate the issue. If possible, please provide a URL to help us troubleshoot the problem

Kindest regards,
Arnel C.

thank you so much for your reply Arnel, url is 

I am using prestashop the module was already installed as part of the back office its version 1.3

It's quite annoying because customers actually want to leave positive feedback.

I am so grateful for your help. I am working alone with prestashop and I love it but it is quite difficult for a non-technical person like myself to always find the solutions to problems. So glad to have found you !!

Kindest regards

Your theme could possibly be interfering with it. If you change your theme, does it start working?
