I'm looking for someone to develop a plugin for abantecart, can anyone help me?
Plug-in function: add a switch to the place where the product is published. After the function is turned on, the purchase product and add to the shopping cart buttons on the page will be hidden, leaving only one purchase button, but clicking the purchase button will jump to another website. Add a place to fill in the URL at the switch where the product is published. Fill in what URL to click to buy a product and it will jump to what URL.

Another plugin is to add a payment interface.

How much is the development cost of the above two plug-ins, and how many days can they be developed.

Thank you very much, much faster

1. Propose customization requirements and open voting stage (10-30 days). When a certain number of votes is reached, the technical side will consider arranging customized products
2. Users who need this custom function pay, if 10 people need it, the total cost is 100 US dollars, each person pays 10 US dollars, if 20 people need it, each 5 US dollars...
3. After the first batch of users purchase, the plug-in can be released and sold in the plug-in market at a price
4. If no one joins in the voting stage, the technical staff will set the price. If the person posting the vote is willing to pay the full amount of custom development, he can also develop this function separately for him, and the same can be put into the plug-in market and sold to others after the development is completed.
With this function, people who use the mall can customize the program according to their needs. The official platform can also draw part of the service fee from it. The development work can be handed over to highly acclaimed plug-in authors, or directly developed by the official.
Over time, it will speed up the establishment of system functions, and plug-ins will become more abundant.

The background that has been running takes 5 seconds to enter, and every time you click on a different page, you have to wait for this time. Only VPN can solve this problem. But you need to disable VPN when releasing the product, it is very inconvenient to switch back and forth

Thanks for the reply, but I don’t know the code well. I would like to ask what position in the file that this code needs to be added in order to realize the automatic adaptation of all released products to the mobile version, thank you

Thanks!
The reason is found, because in the multi-language version, after changing the Price Modifier: to another language, the text box at this position will automatically become smaller and change to Price Modifier: and the display will be normal
