Problem with importing products that have WebP images

pad420 · December 28, 2022

I got about 4000 products on a different platform and when I try to import them with CSV to the Prestashop store 1.7.8.7 , all of the product images that had the Webp file format are completely white.

I guess it's probably because Prestashop doesn't support Webp.

Is there a way to fix this?

Hi, I literally had the same problem recently. I had to write a short PHP script that would convert photos from .webp to .jpg. Just a question - how do you import the products? If you manually write the import code, it's easy to fix the photos

Hello,

Im using the default import wizard which prestashop has on default.

Never thought about making the import code myself.
This is the first time Im importing products and the product images are being downloaded from a different store (at least I think since there are urls to the product images in the CSV) so I don't know if it would be possible

If it's not too complicated I would really appreciate a link with a tutorial or documentation on this 🙏

There is no documentation. I had to came up with my own solution. Later I will post my code for converting webp photos into jpegs.

Is this a 'one time' import and you won't import any products in the future? If that's the case you could just write a script for updating only photos

Hi.
If you dare, editing is easy.

1. open ./classes/ImageManager.php

2. add

3. change function isCorrectImageFileExt

4. add

5. add

6. add

7. save changes and clear cache

8. full source Prestashop 1.7.8.7

Hi.
Thank you, it works perfectly.
Now I can also upload images in the webP product administration.
I also tested import from CSV and it works too.
Good work.

pad420 · December 29, 2022

It worked! Much appreciated.

ps8modules.com · December 29, 2022

I gladly helped 😉

juanrojas · December 29, 2022

I've tried it and it doesn't work

Now it's discussed here, not on github.

Prestashop developers have made it clear that they will not build any new features.

The interviewer needed a modification to import webP images.
Now it can without any problems.

A functional solution was given to the question in the form of Ctrl + C / Ctrl + V.

I was just sharing additional information to fuel the debate, relax.

ps8modules.com · December 29, 2022

People here need immediate solutions.
When they want to read a serial without a resulting ending, they will go to github. How long does it take to solve something on github?
I'm calm, I just take it as pointless to write a link here to something that is not resolved and won't be for a long time.

The solution is integrated into the code since October 15, 2021

The solution is given with all the modified files and it was validated by several people

After that, I don't know if it integrates as is on any version of PrestaShop, but what I do know is that someone who stumbles on this topic will have access to additional information if he wants to go further in his learning.

It is possible that some people like to be given a ready-made solution without thinking, but I know many others who seek to learn to be more independent in their store management so one does not prevent the other.

I confirm for 1.7.8.8 it does not work, paste the complete file, it works fine apparently, but when you try to enter modules it gives problems

mdmax · April 8, 2023

Hi.

Can anyone post solution for prestashop 1.6.1.24?

I tried the solution above for prestashop 1.7.8.7 but it didn't work.

Any help is appreciated.

Hi,
Do you have a solution for prestashop 1.7.8.8 and 1.7.8.9? THANKS

Hi.
If you dare, editing is easy.

1. open ./classes/ImageManager.php

2. add

3. change function isCorrectImageFileExt

4. add

5. add

6. add

7. save changes and clear cache

8. full source Prestashop 1.7.8.7

    }
}

please notice, that this modification only makes pseudo WebP file; obviously, PrestaShop now allow to upload *.webp file, but still write (convert) image to JPEG format; the uploaded file has *.webp extenstion, but is still JPEG image; this is wrong; you can check this by download any uploaded image and review his metadata (for example by open it in GIMP and view Image > Image Properties);

to make real WebP format on upload image, should do one more step; edit ImageManager.php file and add few line to "write" function, as shown in screenshot;

Hello everyone,

I have applied all the changes, by ps8moduly.cz even the last one indicated by Roger Głowacki. I also followed the instructions on Github.

The product images in webp are loaded, without errors, but in reality it is a jpg image.

In other parts of the template I noticed that webp images are accepted, this even before editing the source files. (I have a development and operational version of the site).

It seems that it does not accept product and category images in the webp format. Why does this happen?

Ps v 1.7.8.9

Thanks in advance

I am facing the same error in webp image and looking for solution. But after reading this discussion I am still confused what is the exact solution.😒

Hello,

It is maybe late, but will help some users.

In addition to "ps8modules.com" answer, you also need to change the function isCorrectImageFileExt on the "./classes/ImageManager.php" file:

After this code:

        // Filter on file extension
        if ($authorizedExtensions === null) {
            $authorizedExtensions = ['gif', 'jpg', 'jpeg', 'jpe', 'png', 'webp'];
        }

Add this:


        if(!in_array('webp', $authorizedExtensions)){
            $authorizedExtensions[] = 'webp';
        }

Good luck

Does this solution work with Prestashop 1.7.8.11? THANKS

        }

Add this:


        if(!in_array('webp', $authorizedExtensions)){
            $authorizedExtensions[] = 'webp';
        }

ps8modules.com recommends this code:

public static function isCorrectImageFileExt($filename, $authorizedExtensions = null)
    {
        // Filter on file extension
        //if ($authorizedExtensions === null) {
            $authorizedExtensions = ['gif', 'jpg', 'jpeg', 'jpe', 'png', 'webp'];
        //}
        $nameExplode = explode('.', $filename);
		$currentExtension = strtolower(end($nameExplode));
		if (!in_array($currentExtension, $authorizedExtensions)) {
			return false;
		} else {
			return true;
		}
		
        /*if (count($nameExplode) >= 2) {
            $currentExtension = strtolower($nameExplode[count($nameExplode) - 1]);
            if (!in_array($currentExtension, $authorizedExtensions)) {
                return false;
            }
        } else {
            return false;
        }

        return true;*/
    }

Should it be modified like this ? (for PS 1.7.8.11) :

public static function isCorrectImageFileExt($filename, $authorizedExtensions = null)
    {
        // Filter on file extension
        if ($authorizedExtensions === null) {
            $authorizedExtensions = ['gif', 'jpg', 'jpeg', 'jpe', 'png', 'webp'];
        }

        if(!in_array('webp', $authorizedExtensions)){
            $authorizedExtensions[] = 'webp';
        }

        $nameExplode = explode('.', $filename);
		$currentExtension = strtolower(end($nameExplode));
		if (!in_array($currentExtension, $authorizedExtensions)) {
			return false;
		} else {
			return true;
		}
		
        /*if (count($nameExplode) >= 2) {
            $currentExtension = strtolower($nameExplode[count($nameExplode) - 1]);
            if (!in_array($currentExtension, $authorizedExtensions)) {
                return false;
            }
        } else {
            return false;
        }

        return true;*/
    }

Thank's !

Thank's !

It is working without commenting this code :

		
        /*if (count($nameExplode) >= 2) {
            $currentExtension = strtolower($nameExplode[count($nameExplode) - 1]);
            if (!in_array($currentExtension, $authorizedExtensions)) {
                return false;
            }
        } else {
            return false;
        }

        return true;*/

You can try with the code commented, else try to uncomment the code.

Good luck
