Question

I have array with both image colour and image id values.

I can echo this info, but I don’t know how to get this into js file.

My js file is like this:

$(document).ready(function(){

    var colour = false;
    $('.options').click(function(){
        colour = $(this).val();
        console.log(colour);
        if(colour == 'White'){
            var imageid = 758;
        }
        else if(colour == 'Black') {
            var imageid = 752;
        }
        else if(colour == 'Light Oak') {
            var imageid = 755;
        }
        else if(colour == 'Rosewood') {
            var imageid = 757;
        }
        else if(colour == 'Green') {
            var imageid = 754;
        }
        else if(colour == 'Red') {
            var imageid = 756;
        }
        else if(colour == 'Blue') {
            var imageid = 753;
        }
        else {
            var imageid = colour;
        }


        $('.options-input').val(imageid);

        console.log(this);

        $.post("index.php", { image_id: imageid }, function(results) {
            $('body').html(results);
            console.log(results);

         });    
        console.log(url);
    }); 
});

I am doing this manually at the moment and on click I can post imaged to my index.php

$_POST['image_id'];

Works from there.

Problem is that I want to create js statement dynamically depending on what values new array will have.

After you’ve changed your question I’d like to answer again. It seems like you want to deliver an image according to the color a user has selected from a element within the page. You haven’t posted your PHP script, but let me tell you that what you’re doing right now would be way better to be done via PHP.

$(document).ready(function () {
  $('.options').click(function () {
    var color = $(this).val();
    if (color !== undefined && color !== null && color !== '') {
      $.post('index.php', {color: color}, function (response) {
        $('body').html(response);
      });
    }
  });
});

And in your PHP file do the following:

<?php

if (isset($_POST['color']) && !empty($_POST['color'])) {
  $colors = array(
    'White' => 1234,
    'Black' => 4321,
  );
  if (array_key_exists($_POST['color'], $colors)) {
    echo $colors[$_POST['color']];
  }
}
