Like Dislike system with PHP and MySQL

This system works exactly like the Like/Dislike system TH-cam implements for its videos. On TH-cam, the buttons are placed on videos. Since we are not building the next TH-cam, we will stick with using simple posts where users can click on their associated like and dislike buttons.

Amazing clarity. You probably maxed this out Bro.. It's so nice to see a new version of this demonstration in every 1-2 years from you. Respect, W

[@shraddhadodiya007]

Very much use full video, sirji...thankyou so much sir..for this clarity and for source code🙏

[@TheSuperhans49]

Good job - it does take a short moment to apply the like after clicking on it - but it works good, thank you!

[@vusisibiya7527]

Your tutorials are always on point. Thanks a million!

[@user062]

For everyone saying it doesn't work:
1. make sure you have set $user_id somehow
2. in the SQL statements put ' ' around the variables (variable = $...)

If anyone has multiple comments and from comments, if it has numerous replies then the rating_info table has to include more columns.

[@amanagarwal7256]

Use stringyfy instead of parse

If code give you "Unexpected token < in JSON at position 0" error change "JSON.parge" with "JSON.stringify"

Please create FILTER.

[@AwaMelvine]

Hey Rey Basilio, Thanks for watching! what kind of filter are you referring to? Can you please elaborate?

[@reybasilio6075]

Using Option button. Example in school. When i choose IT, all the students of IT only will display in the form.

[@reybasilio6075]

Ahh. I think it was a JQuery Filter? Using option button.

ahaha. I'm not having any inserted data on my database whenever I clicked the like button

[@mackynikat8833]

. yes but the whole code for me seems doesn't work . if your asking how did i done it just check your jquery syntax , the brackets, y spelling of the of statements . he's code is working until the loop

[@mackynikat8833]

@Clash Guy in mine the situation was about users liking the same comment . for sure it's inside the loop . you can also try if your havind bad creating each function on each comment section to insert on database . that's what i did

[@TheSuperhans49]

Great script, thanks - but i can only like it once even if i like it from another device like from my mobilephone.
