implement like button increment in php ajax

[ochen_jamir]

Hi All,

 

I am implementing a facebook like "Like" button counter so everytime a user clicks on the button, via an ajax call a DIV tag besides it updates it from the db (see logic of the code below). However it isn't working. Please see all codes below:-

 

I have copied the code from the w3schools php ajax tutorial page and made some modifications for the button click call.

 

javascript:

MySQL:

HTML:

<img src="./images/like.jpg" style="cursor:hand;" onclick="likeAJAX(<?php echo $_GET['val']; ?>)"><?php echo $likeVal; ?> people like this</span>

Seems like the onclick isn't working, i have tried putting an alert on the javascript function but it isn't getting triggered. Is it some typo/syntax error with the javascript function onclick not being able to recognize the php variable being called.

 

Regards,

 

Ochen

Start by opening your browser's developer tools and checking the console, if there are any error messages they will be listed there. Also, check the HTML that gets outputted to make sure that things are formatted correctly after PHP runs.
