Flex Slider - How to add same controls for two sliders

Question

I am using Flex slider for one project. I need to control two sliders on one page with same controls.

One part is main slider that will show images, and the second one is text (in this case it will be taken from "the_excerpt" in WP ).

Basically, this is the code I am using to call two slides on one page:

  $(window).load(function() {
    $('#main-slider').flexslider({
      animation: 'slide',
      controlsContainer: '.flex-container'
    });

    $('#secondary-slider').flexslider();
  });

Now, I need to "connect" both of them to same controls, so when I click on arrow, it will slide/fade both of them.

You could accomplish what you're trying to do by ditching the controlsContainer setting and creating your own navigation that you then link to both sliders. Here's an idea of how (please note it's untested)

Your markup would look something like this. Note the rel attribute on the links - we'll use them below. Also note that the values start from 0 - this matches the values for the slides (e.g. the first slide is 0, the second is 1 etc).

<a rel="0" class="slide_thumb" href="#">slide link 1</a>
<a rel="1" class="slide_thumb" href="#">slide link 2</a>
<a rel="2" class="slide_thumb" href="#">slide link 3</a>
<a rel="3" class="slide_thumb" href="#">slide link 3</a>

<div id="main-slider" class="flexslider">
<ul class="slides">
    <li>
        <img src="image1.jpg" />
    </li>
    <li>
        <img src="image2.jpg" />
    </li>
    <li>
        <img src="image3.jpg" />
    </li>
    <li>
        <img src="image4.jpg" />
    </li>
</ul>
</div>

<div id="secondary-slider" class="flexslider">
<ul class="slides">
    <li>
        <p>Text 1</p>
    </li>
    <li>
        <p>Text 2</p>
    </li>
    <li>
        <p>Text 3</p>
    </li>
    <li>
        <p>Text 4</p>
    </li>
</ul>

Then you set up the call to flexslider

<script type="text/javascript" charset="utf-8">
jQuery(document).ready(function($) {

$('#main-slider').flexslider({
    animation: "slide",
    slideToStart: 0,
    start: function(slider) {
        $('a.slide_thumb').click(function() {
            $('.flexslider').show();
            var slideTo = $(this).attr("rel")//Grab rel value from link;
            var slideToInt = parseInt(slideTo)//Make sure that this value is an integer;
            if (slider.currentSlide != slideToInt) {
                slider.flexAnimate(slideToInt)//move the slider to the correct slide (Unless the slider is also already showing the slide we want);
            }
        });
    }

});

$('#secondary-slider').flexslider({
    animation: "slide",
    slideToStart: 0,
    start: function(slider) {
        $('a.slide_thumb').click(function() {
            $('.flexslider').show();
            var slideTo = $(this).attr("rel")//Grab rel value from link;
            var slideToInt = parseInt(slideTo)//Make sure that this value is an integer;
            if (slider.currentSlide != slideToInt) {
                slider.flexAnimate(slideToInt)//move the slider to the correct slide (Unless the slider is also already showing the slide we want);
            }
        });
    }

});

});
</script>

Basically both sliders are controlled by the same set of navigation links. Think this should get you moving in the right direction but shout if you need anything explained.

For Flexslider 2, you can use sync: "selector" option. Just set one of the sliders' controlNav: false.

$(window).load(function() {
    $('#main-slider').flexslider({
        animation: 'slide',
        controlNav: true,
        sync: '#secondary-slider'
    });

    $('#secondary-slider').flexslider({
        controlNav: false
    });
});
