Dynamic Image Alt Tag?

KrisCons

Hi all,

I store a path to an image in a variable as such:

$imageref = "images/image1.jpg";

And I then echo this to the screen within IMG SRC tags as such:

What I would like is to be able to take the 'image1' part of the string and use that as the ALT tage for the img src above.

Can anyone explain how this is done please?

I can't hard code my alt tag because I retrieve the string from a database and therefore it is a different image everytime.

Many Thanks (in advance)

$alt = preg_replace("|^([^\.]+)|", "\\1", $image);

Hi Kudose

Thanks for the prompt reply, but unfortunately this displays the full path and image type extension e.g. images/image1.jpg as the alt tag.

I need it to simply say image1 (just the image name, and not the path or the filetype extension).

Many Thanks.

Sorry about that. Guess I shoulda tested it ...

<?php
  $image = "images/google.jpg";
  $alt = preg_replace("|^[^/]+(.*)\.(.*)$|", "\\1", $image);
  $alt = str_replace("/", "", $alt);

  echo $image.'<br>'.$alt;
?>

Hi,

How about just using the following:

echo substr($imageref, strrpos($imageref, "/") + 1, -4);

Hope it helps.

Thanks.

Why not just use [man]basename[/man]?

Cause that's toooo easy.
