AngularJS: Images failing to load (Not Found) with curly brackets in URL

This is one of those schoolboy errors that, in hindsight, is blindingly obvious and I should have been able to work out for myself, but required a bit of searching before I managed to ask Google (other search providers are available) the right question.

Basically, I had a load of image src paths that were defined using AngularJS expressions, e.g.

<img src="content/images/results/{{result.id}}.jpg" />

The images loaded fine, but I kept getting 404 (Not Found) errors on image URLs that contained the curly brackets of my expressions (/content/images/results/%7B%7Bresult.id%7D%7D.jpg). This seemed like it was because the page was trying to load the images before Angular has done it’s work and converted the expressions into sensible URLs. And that’s exactly the problem!

The solution is a simple one: use ng-src instead of src if the URL has an expression in it, e.g.

<img ng-src="content/images/results/{{result.id}}.jpg" />

Adding an image to a child theme template (e.g. header/footer) in WordPress

Child themes in WordPress are great, because they allow you to modify a theme without making changes to the theme’s core code, which makes things much easier when the theme gets updated – you don’t have to redo all of your changes.

I wanted to add an image to a custom footer template in a child theme (created by copying footer.php from the parent theme). I’d created an images directory in my child theme and put my image there, but was struggling to generate the correct link to the image.

After a bit of searching, I found this suggestion:

<img src="<?php echo get_template_directory_uri(); ?>/images/image.jpg" />

However, this was pointing to the image directory in the parent theme, not the child theme. Further searching led me to this blog: How to load files within WordPress themes, which had the answer (and explains things in more detail):

<img src="<?php echo get_stylesheet_directory_uri(); ?>/images/image.jpg" />

The basic difference, when using a child theme, is this:

  • Template refers to the parent theme
  • Stylesheet refers to the child theme

More information on the get_stylesheet_directory_uri() function can be found here: http://codex.wordpress.org/Function_Reference/get_stylesheet_directory_uri

Note: an alternative is to use the bloginfo() function (echo is not needed), as follows:

<img src="<?php bloginfo('stylesheet_directory'); ?>/images/image.jpg" />

However, it turns out that this is just an indirect way of calling get_stylesheet_directory_uri(), via get_bloginfo() in wp-includes/general-template.php. Both are included in the codex, so I don’t think it really matters which you use.

Another note: Dropping the _uri from the end of the function (i.e. get_stylesheet_directory()), will return the absolute server path to your child theme stylesheet directory, which can be used for including a another php file, e.g.

<?php include( get_stylesheet_directory() . '/includes/myfile.php'); ?>
