around this issue I have a page which view links from the database. Now I want that if i pressed on any of these links i will be in another page but still have the variable name i have presses to do some queries on it. , Try :
in your first page:

code :

 $query = "SELECT Category FROM product WHERE Visible = 0";
    $res = mysqli_query($con,$query);
    echo "<div style = 'font:40px/60px Arial; color :orange'>All Categories Available :-</div>";
    while($row = mysqli_fetch_array($res))
    {
        $c = $row['Category'];
        echo '<li>'.'<a href ="page2.php?value=>'.$c.'</a>'.'</li>';  // i put value as variable in redirected page.
    }

if(isset($_GET['value'])){
$url_val = $_GET['value'];
echo $url_val;    // your first page value.
 // do your work
}

jQuery: How do I set a variable on page load, on page resize destroy the variable, and then load a new variable?

it fixes the issue So I'm using some jQuery that I found online. There's a lot of variations of it that all do the same thing to help you create divs of equal height. The code I'm using is like so when I load a page. , Unset the min-height so that the div gets height gets recalculated.

code :

$('document').ready(function(){

    var $equal_height = $('.equal_height'),
        $col_a = $('.equal_height_div1');
        $col_b = $('.equal_height_div2');

    // calc the highest column
    // we assign this the return value of a function to make sure its always fresh.
    var heighest = function($col_a, $col_b){
        // Cache variables in closure
        var $col_a, $col_b;
        // this is where the magic happens
        return function(){    
            return Math.max( $col_a.height(), $col_b.height() );
        }
    }($col_a, $col_b);

    // Run once on ready to equalize columns
    $equal_height.css('minHeight', heighest);

    $(window).resize(function(){
       // By unsetting minHeight the column gets its real size back 
       $equal_height.css('minHeight', 0)
            .css('minHeight', heighest);
    });  

});

seems to work fine on click of the button send the value of the first row to jquery and make a ajax call to second page and do the required calculations when ever by response of second page replace the button with result look for examples.
http://api.jquery.com/jQuery.ajax/

code :

<span id="result">
<button id="my-button">Get Score</button></span>

$("#result").html(you calculation result jquery variable);

Passing AJAX variable into .php page and load that page and echo variable

By : Xiao Jianhua

it should still fix some issue You can't echo the variable this way because you have two different requests for the same page:
The first is the AJAX request when you send the data to your page where you do some action and the return; The second one when you access insert_profile.php page, when your value is lost.

code :

    $.ajax({
      type: "POST",
      url:'insert_profile.php',
      data: {item_num : item_num},   
      success : function(data) {
         alert(data);  
      }
  });

<?php $s_n = $_POST['item_num']; 
  echo $s_n;
  exit;
?>

PhantomJS; If I set a variable inside page.evaluate(), how can I access the value of that variable outside of page.evalu

To fix this issue You can return from the evaluate callbacks. I guess you want

code :

function(user, pass, debug){ // step 3 submit Login
  reloadAfterLogin = page.evaluate(function(user, pass, debug){
    if($("form").attr("action").indexOf("login.do") > 0){
      $('form').submit();
      return true;
    }
    return false;
  }, user, pass, debug);
}
