Pass variable from php to javascript

[wemustdesign]

I have a form, I have successfully passed the username from jquery

 

$.post("cplfunctions.php?action=checkUsername", { username: username },

 

to php script. The php script checks the database to see if the username exists:

 

if ($num >=1){
	$status= '0';		
	}else{
	$status= '1';	
	}

 

 

How do I pass the variable $status back to the javascript file?

echo it. Then in jQuery you need to create a function to handle the response.

Can you point me in the direction of how to create a jquery function to get the response? I know a little php but not 2 good with jquery

Given your examples:

 

cplfunctions.php

if ($num >=1) {
  $status = '0';
} else {
  $status = '1';
}
ecuo $status;

 

And the jQuery.

 

$.post(
  "cplfunctions.php?action=checkUsername",
  { username: username },
  function(d) {
    console.log(d);
  }
);
