WordPress Attachment Page Template Code Snippets

Date: 15th November 2009 at 4:25 am | Filed under: scripts, wordpress | Author: Sam Burdge | Tags: , , , , ,

I haven't written as many WordPress tutorials as usual lately, as I have been so busy building websites and blogs, so I thought I would take the time out to share a few WordPress codes I have developed recently for attachment page templates and specifically the image attachment page template. The attachment page template is the page that displays a single image when the images link URL is set to 'Post URL'. You can set the image's link URL when inserting a single image into a post, and also when using the gallery shortcode.

The codes in this article are mostly applicable to images inserted using the gallery shortcode as they are most useful for posts or pages that have multiple image attachments. Read more about using image and file attachments.

These template codes can be added to your WordPress theme using the attachment.php and image.php files. If these template files do not exist in your theme you can create them, or WordPress will default to using single.php or index.php to show attachments by default. (See more about template hierarchy).

If you don't want to create a seperate image.php or attachment.php template you can always edit the index.php or single.php files and wrap the attachment specific codes in the is_attachment clause like so:

if(is_attachment()){
//attachment page specific code goes here
}

These php functions are loosely based on code I found in this article: Adding text links to WordPress Gallery by Michael Fields. In this article he provides code examples of how to show previous and next thumbnail links in a WP attachment page. I also made use of this previous-next keys in array function which is infinitely useful!

My first set of functions will return text links for previous image, next image and back to gallery. The functions themselves will need to be added to your theme's functions.php file before calling them in your image.php or attachment.php files. So here we go:

    Hi this is a great tutorial. I’m currently using nextgen gallery but want to try your gallery on my sister’s blog…so using the built in image features of WP seem to be the best solution. What you have here should be perfect for her. Great job. One question, If I wanted to have the images themselves link to the next image…how wold i do that?

    This worked perfectly for me … except, for some reason I can’t get the image captions to display. Any thoughts why they might not be coming in?

    First let me say, I am an experienced computer/internet user, however my developer side is still just an apprentice. But as a user, the second I saw white and other colored text on black background, I closed it and went on. I decided to come back and let you know because I’m sure I’m no the only one who’s done so. You might want to see what other developers think and if this technique is advisable. At least my eyes are hurting right now. Peace.

    Hi, nice tuto ! I just want to say I think the function array_navigate / prev_att_link / next_att_link could be done with one line of code ! See the wordpress function : wp_link_pages(); (http://codex.wordpress.org/Function_Reference/wp_link_pages) and to see an exemple you can look the code of the attachment.php twentyten wordpress theme.

    Sorry, it’s not wp_link_pages () but previous_image_link(false) and next_image_link () with false option to insert the title : http://codex.wordpress.org/Function_Reference/previous_image_link

    This tutorial is good. But it difficult to read because of the page color. Font size if too small. As a web developer I Suggest you to make your template white color. and big font size.

    When I split an article into 2 column the first row of the second column start one line bottom.
    How can I prevent this?

    Thank you. I appreciate your job and I’ll use it when this “bug” will be take off.
    Great work!

    Thanks manos! Taking the two leading spaced off the end of the functions.php file worked great. Thanks!

    Thanks for the thumbnail function! Works great!!!
    The selecting of text with your particular color scheme is hard to see though!
    Excellent work =)

WordPress attachments hack

Date: 9th June 2009 at 3:19 pm | Filed under: blog, development, scripts, wordpress | Author: Sam Burdge | Tags: , , , , , ,

While working on a WordPress site recently I came up against a problem that had never occurred to me before. The client wanted each post excerpt on the homepage to include an image which when clicked would link to the main post (permalink) itself. The built in functions of wordpress when inserting an image allow you to link to either the 'File URL' (i.e. the full size version of the image) or to the 'Post URL' which is actually an attachment page in wordpress which displays the image, but does not include the text of the actual post itself. However, without either editing the html of each post (not an option for this client) or inserting the image without a link, and then adding the permalink to the image (too long winded) there was no simple way to create the image links in the way they wanted them.

My solution to this was to create a very basic hack which would allow them to use the 'Post URL' link when inserting images, but instead of linking to the attachment page, the link would automatically be updated to link to the post's permalink itself.

Here is the basic php function that you would need to insert into your theme's functions.php file:

function lose_attachment($content){
return preg_replace('/<a(.*?)href="(.*?)\/attachment\/(.*?)"/i', '<a$1href="$2"', $content);
}

add_filter('the_excerpt', 'lose_attachment',2);

This will remove the 'attachment/name-of-image-file' part from the URL making it link to the post's permalink itself.  I hope someone out there finds this useful!

    Hi Sam. Thanks for your post, really useful. But I would have another thing:
    I want change permalink of attachment file from

    http://site.ext/postname/postname-post_id.html/attachment-name

    to

    http://site.ext/photos/attachment-name

    Is it possible?

    Thanks a lot for your support

    You might also try the AutoNav plugin, which will automatically generate thumbnails and links to child pages, to posts in a category or by slug or author, or by page/post ID:

Forcing a file to download using php headers

Date: 4th May 2009 at 11:57 am | Filed under: development, scripts | Author: Sam Burdge | Tags: , , ,

If you create a hyperlink to a media file that can be opened within the browser such as an mp3, mpg, jpg, pdf, etc. a single left click will open the file in the web browser instead of triggering a download. To download the file you need to right click (CTRL + click for mac) and choose 'Save File As...' from the dropdown.

If your intention is to create a link for the user to download the file rather than viewing it in their browser you can do so using a simple php script. Create a file called 'download.php' and copy in the following php:

<?php
$download_file = $_GET['file'];
$download_file_name = $_GET['name'];
$handle = fopen($download_file, "r");
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.$download_file_name);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($download_file));
ob_clean();
flush();
readfile($download_file);
fclose($handle);
exit;
?>

You can then create your download links like so:

www.example.com/download.php?file=images/example.jpg&name=hello.jpg

The URL should include the path to the file to be downloaded, and the name you want to give the file. In the above example the file is 'images/example.jpg' but the name of the file downloaded by the user would be 'hello.jpg'

When using PHP headers it is important to note that the headers will only be executed if they are called before any text is output to the page. Any html, or php echo tags, before the headers will cause the headers to be ignored. A line break or space before the opening php tag will also prevent headers from working.

little bits of mischief website

A simple 5 page site built for music composition, sound design and music searches company 'little bits of mischief'. The site is built in php / XHTML and features Flash audio and video players. It's always a pleasure for me to build simple, classic designed sites. I particularly like the red, white, blue colour scheme in this design.

    Hi Lynette
    I don’t see how this question relates to this article, but:
    1. Draw a circle
    2. Convert your circle to a button
    3. Create a keyframe on the over state of the button
    4.select the circle in the over keyframe and covert it to a movie clip.
    5. edit the movie clip to include a motion tween
    6. on the first frame of the motion tween edit the frames properties - setting rotation to either clock-wise or counter clock-wise
