Modify code for inserted images, possible?

Anyone, please?
I’d like to replace the anchor tag with a div, is that possible?

Something along these lines would do it. Add this to your theme’s functions.php file.

add_filter( 'image_send_to_editor', 'div_stuff', 10, 7);
function div_stuff($html, $id, $alt, $title, $align, $url, $size ) {
return "<div class='whatever'>$html</div>";
}

I’m just starting to learn PHP, so I don’t know how to use the information you just provided me.

Could anyone help me, please?

Not much to explain beyond what Otto already said…

Does your theme have a functions.php file?

If yes, edit it and copy/paste what he gave you before the final ?> at the bottom of the file.

If no, create one. Start it with <?php then otto42’s code then ?>

The last time I tried it didn’t work, but this time the div I want to add appears twice. Looks like this:

<div class="whatever"><a href="https://localhost/wp-content/uploads/2008/06/large-image.jpg">
<div class="whatever"><img class="alignnone size-medium wp-image-24" title="image-name" src="https://localhost/wp-content/uploads/2008/06/small-image.jpg" alt="" width="400" height="300" /></div>
</a></div>

I have two questions:
How can I avoid having that div duplicated?

I don’t want an anchor tag inside the div, how can I prevent it from being inserted automatically?

Thanks in advance.

Since the div “whatever” appears duplicated and I want to prevent the anchor tag from being inserted, I thought it would be good to try something else.

From the code Otto42 gave me, I modified it to be like this:

add_filter( 'image_send_to_editor', 'div_stuff', 10, 7);
function div_stuff($html, $id, $alt, $title, $align, $url, $size ){
return "<div class='whatever'>
<img class='alignnone' title='$title' src='$url' alt='' width='400' height='300' />
</div>";

The problem with this code, is that the $url variable gives me the url for the large image, not for the medium sized image, which is the one I need.

Thanks in advance.

That should not happen, so I took a look, and there’s a bug in 2.5.1 that creates the multiple div problem you’re seeing.

Bug is documented here: https://trac.www.ads-software.com/ticket/6806

It’s been fixed in the latest version of WordPress, and will be fixed in 2.6.

To fix it right now, replace your wp-includes/media.php with this one:

Thank you very much, Otto42. It fixed the duplicated div issue.
Now the only problem I have, is that I cannot remove the anchor tag inside the div.
I’m starting to think that’s not possible.

I solved the last problem. I was entirely focused on the div issue that I forgot to play with the options.

Again Otto42, thank you very much for your help and for being so patient with a newbie like me.
