Passing Variable Javascript To Php Using Ajax

I am trying to pass a single variable from javascript to PHP using jQuery AJAX. Javascript: $(document).ready(function() { $('.ok').on('click', function(e){ var value

Solution 1:

Instead of this

data: ({value : value}),

Try using this,

data: "value="+value,

And you are not at all passing "OK" but you are receiving it. If you want to pass OK also as a parameter try this.

data: "value="+value+"&OK=Somevalue",

That should work.

Solution 2:

Your JavaScript

data: {'value' : value}

notice the single quote and no parenthesis

Your PHP:

If(isset($_POST['value'])){
   $val = $_POST['value'];
}

Your JavaScript was formatted incorrectly. data is an object, or an associative array in other words.

Your PHP code has unnecessary string comparison. Whenever a post is made to a PHP script, you will access them using $_POST array.

For instance, if you posted this via AJAX

data:{ 'name' : 'jake', 'age' : 1024}

You would access them in PHP by

$name = $_POST['name']
    $age = $_POST['age']

Also, it is wise to use PHP isset to verify that a post variable exists before trying to access them. That way you will not have an exception if expected post data is not.

Solution 3:

check following line

var value = $(this).find('td:first').html();

set some hard coded value for 'value' variable like below

varvalue='some value';

if above works then check the value you assigned using $(this).find('td:first').html()
