Where would be the correct place to put an images directory in the code igniter directroy tree?
How would I reference the images in code eg. <img> tag and in css background element?

I put images/js/css/etc… in a resources folder outside of the system directory.
Accessing it is easy.


<?=base_url();?>resources/images/yourimage.jpg

I use the xhtml element <base> to set a global base url with the PHP CI base_url function. Like this:

<base href="<?=base_url();?>" />

// Now anything with an href will append the base href above before the rest of the URI.

<a href="/resources/images/yourimage.jpg">My image is here</a>

(Please) help me understand the above ...

Is it true that the above base setting would only apply within the single (e.g. view) file in which it was set? ... right?

... i.e. it wouldn’t/couldn’t apply “globally” (e.g. like defining a PHP CONSTANT) for one’s whole website? ... right?

I ask while pondering this:
... about the time cost of excessive function calls, like base_url().

It would apply ONLY within the scope of the DOCUMENT. Don’t look at it as in a ‘single view’ because it doesn’t apply to views, it applies to the XHTML DOCUMENT that is being OUTPUT by the application.

<html>
<head>
  <base href="somebaseurl" />
</head>
<body>
  <a href="--base--/whatever/url">link</a>
</body>
</html> 

In other words, anything between the start and end HTML tags will be affected by the <base> element. If you have another view that is outputting a completely different XHTML document to the browser you would have to define another <base> element (or not if you don’t want it).

[EDIT]
Anything inside the <head> element will not be affected by <base>, only elements within the <body> element can be affected - but, the scope is still within the document since you can only have one <body> element per <html> root element.

Thanks - for the clarification/validation, Iksander.

` looks like the xHTML <base> element would be useful in reducing function calls (e.g. base_url() ), if one needs to place a number of images (or even other objects) within the same HTML document/template.

I have

/codeigniter
/www
/www/img
/www/js
/www/css

An image tag is simply /img/someimage.jpg

Why do you need the base tag when its an relative path?

Well, typing relative paths all over creation can get messy ... and, more importantly, can be a mess to maintain, if ever changed ... or if the site gets moved. Life can be easier, if one has an xHTML <base> reference and/or a PHP CONSTANT which can be updated, once i.e in one place.

the HREF attribute does not have to be set with base_url(). It can easily be used for relative paths, and is much handier than typing a base relative path all over the place, personally.

EDIT, too much beer, not sure that last statement made any sense…

How would the method described here compare to the notes in another thread ?

I am new, trying to make heads or tails as to where to put my images. And why (assuming there is an advantage to some method over another).

Any guidance?

I prefer this method, because it keeps the ‘public’ resources away from my core functionality - I also separate my application folder from the system folder (by taking it out of the CI directory altogether) to keep CI Core more easily updated.

Generally I will make a folder in the same directory with my separated CI directory named after whatever the project name is - then I have the application directory within that directory with a directory named ‘public’ along side that…

Hope that helps, alot of info if you search for it on the forums.

Optionally you could use the helper “Snappy Source” I created.

Wow, it’s not every day you learn a new HTML tag. Nice.

I think the <base> alternative probably works best in terms of efficiency and speed, since you can just create a header view and plop in that base tag right there. Change the structure, you just change the view file. Only ever one function call per page (with regards to images).
