Add slides to Bootstrap 3 carousel dynamically using jQuery

First thing, I will rely on the fact that m is an array with proper url to your images.

The HTML should be like this:

<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators"></ol>
  <!-- Wrapper for slides -->
  <div class="carousel-inner"></div>
  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left"></span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></span>
  </a>
</div>

Class carousel inner is empty, there is where you gonna place your images for then carousel.

Class carousel-indicatiors is also empty, will be filled by JS.

Then, comes the JS:
(as I said, Im relying on the fact that m is an array of imgs url)

$(document).ready(function(){  
  for(var i=0 ; i< m.length ; i++) {
    $('<div class="item"><img src="'+m[i]+'"><div class="carousel-caption"></div>   </div>').appendTo('.carousel-inner');
    $('<li data-target="#carousel-example-generic" data-slide-to="'+i+'"></li>').appendTo('.carousel-indicators')

  }
  $('.item').first().addClass('active');
  $('.carousel-indicators > li').first().addClass('active');
  $('#carousel-example-generic').carousel();
});

Basically, you append all your images to class carousel-inner, you add carousel control li’s, then you add the active class to the first image and to the first carousel indicator li., and finally, you initialize your carousel. Note that all this is inside a document ready function, which is what you are missing. What you do is only define a function called onload

Hope it helps !

EDIT: I saw that you are outputting also alt tag to images, but thats something that not need to be on my answer, I bet you can do that without problems.
