How would I use PHP to copy the filename into the alt attribute? For
example,

<img
src="a-really-long-filename-that-I-also-want-to-use-without-hyphens.jpg"
alt="<?php echo("WHATTHEHECKGOESHERE?"); ?>">

I see! try this out:

<script type="text/javascript">
function loadAlt(){
var imgNodes = document.getElementsByTagName("img");
for(var i=0; i<imgNodes.length; i++){
var cleanedSrc = imgNodes .src.replace("-", "");
imgNodes.setAttribute("alt", cleanedSrc);
}
}
</script>
</head>
<body onload="loadAlt()">

Hope it will help, it's late here and I am ready to go to bed :-)

I was first thinking that I could use the PHP to determine the value of the
src attribute for that particular image. But I realized on reflection that
that would come from the DOM.

I have my reasons! 8)

I attached a DW's query you can use. It doesn't strip the dashes out, but
adds an alt attribute, with its value being equal to the src attribute. It's
a quick and dirty solution, so please be careful, backup first and test it.
Keep in mind it assumes the alt attribute is totally missing.

Hope it could help

BTW I hope other forum users don't mind the attachment...

If it's a static page, then you'd HAVE to use javascript...as PHP only
executes server-side.

Yes, javascript would work.

I imagine the logic would be to:

- find all IMG objects on page and set to an array.
- loop through the array grabbing each img's SRC
- parse the string
- replace value of alt with new string

Alas, you'll have to wait for one of the javascript experts to actually show
you how to do that ;o)

Again, though, a filename isn't terribly useful in the alt attribute in most
cases.

It's a static page!

Hmm - I think I will have to do it with javascript. I have a page with a
bunch of images on it. I want to snoop out each src attribute's value,
strip the dashes out, and place the resulting string into the alt attribute.

Why would you want the filename in the alt attribute?

If you did, though, PHP being server side, you'd just serve the SRC and ALT
attribute the same string variable.
