  • I need to edit the link which is displayed when a single attachment is being displayed – but I don’t know where this link is put together!

    Let me explain..
    I have a Blog post which has several attachments (images):

    I managed to edit the code so every image links to a page where the image itself is displayed:

    Now the question for me is, how or where do I find the code which is used to create the last link, that is being opened when I click on this single image (and which leads to the upload folder and the image itself):

    I need to edit this behavior, so it still displays the image from upload folder, but links to an external side.
    I can’t find where the imagelink is being created. I got as far as
    <?php the_content('<p class="serif">Read the rest of this entry &raquo;</p>'); ?>

    Which is the part that displays the image, bvut I can’t find the_content function.

    Besides, the code which is used to create the attachment links to each single image looks like this:

    <?php echo '<a class="postImg" href="' . get_permalink( $attachment->ID ) . '" title="' . esc_attr( sprintf( __( 'View' ), $att_title ) ) . '" rel="permalink">'; ?> <img width="<?php echo $image_attributes[1] ?>" height="<?php echo $image_attributes[2] ?>" src="<?php echo wp_get_attachment_url( $attachment->ID , false ); ?>" alt="<?php the_title(); ?>" width="280" border="0" /></a>

    I am new to WordPress and pretty new to PHP, too – so please forgive my stupidness!

    It’s very challenging to find where anything happens in WP. the_content() is located in wp-includes/post-template.php. You will see there is the filter ‘the_content’ you can use. Your filter hook function is passed the entire post html. If you can figure out a way in code to search the html for that particular link and replace it, then you you have a solution. Just return the altered html from your filter hook function.

    Actually I want to have ALL imagelinks to point to a certain, external url..
    I am currently looking into post-template – I’ll let you know if I found something.
    Thanks bcworkz!

    Found it!

    function prepend_attachment($content)
    function wp_get_attachment_link($id = 0, $size = ‘thumbnail’, $permalink = false, $icon = false, $text = false )

    had to be edited. Thanks a lot bcworkz!

    FWIW, it’s poor practice to edit core files. Both those functions have filters you can hook to alter their output, then your code will be safe from being overwritten by updates.
