Can I get imagefield to NOT create thumbnails? - drupal

I'm working in Drupal 6. I need thumbnails for the images that are getting uploaded to my site, but, for a variety of reasons, I need several different sizes for different kinds of images. Thus I'm in effect rolling my own thumbnails with imagecache and adding some hooks to get them inserted into the right places. The result is that I don't really need or want the thumbnails that imagefield wants to generate, and would prefer not having them clutter up my server. Is there any way to get imagefield to just not create these thumbnails? Or would that screw up something else that I'm not thinking about? Thanks!

there aren't any ways to do this without hacking the module, which is a shame!
Try this:
When you create your own thumbnails, run the following code on the uploaded file.
file_delete(imagefield_file_admin_thumb_path($file, FALSE));
Here's the function in imagefield_file.inc (called on line 22 in imagefield_file.inc):
/**
* Implementation of hook_file_delete().
*
* Delete the admin thumbnail when the original is deleted.
*/
function imagefield_file_delete($file) {
if (imagefield_file_is_image($file)) {
file_delete(imagefield_file_admin_thumb_path($file, FALSE));
}
}
I can't test it at the moment I'm afraid, but it might be a starting point! It's also a bit messy, as the thumbnail will be generated, and then deleted! According to line 12 in imagefield_file.inc, the thumbnails are generated on preview...you might be able to override this somehow?

How to add an HTML class to all image attachments on posts in Wordpress -- except homepage

Sorry for the length, my problem is very simple, but specific.
I'm building a wordpress site that automatically imports image galleries from a Tumblr account, then styles and displays them. The backend is finished, and all that I need now is have all images in posts be displayed as thumbnail sized links. They are not behaving well with the importer (I've tried 6), so I have to edit the HTML display (rather than the images as they are uploaded).
I have decided to do this by applying class="attachment-thumbnail size-thumbnail" on all images on the site (in HTML). I have tested this and they will open the proper gallery in a lightbox as necessary so long as they belong to those two classes.
I have a two part problem.
I do not know PHP past basic syntax, and while I can intuit most of what is happening I don't trust myself to edit Wordpress source code without understanding exactly what I am breaking.
From other answers I've learned that I should most likely edit the wp_insert_attachment() function in post.php under wp_includes/. I have found the function, but don't really know where to go from there, as it does not appear to be specific to image attachments. I don't want to throw any errors by assinging image classes to non-image attachments. How do I add those two classes (attachment-thumbnail and size-thumbnail) to all post images (and only images)?
There is a single exception to this rule. I want a large image on the homepage, and have it not be a link.
It seems like the way to handle this would be to allow page attachments to be handled normally, while attachments that are both images and attached to posts should trigger this:
if [attachment is an image AND is on a post, not a page]:
<img src="https://whatever">
becomes
<img src="https://whatever" class="attachment-thumbnail size-thumbnail">
tl; dnr: ^^ that's all I need to happen, in PHP, in the right file, in Wordpress ^^
Thanks!
So likely you will want to do it via php but instead you could do it with javascript ie jQuery:
<script>
$(function() {
$("body img").addClass("attachment-thumbnail size-thumbnail");
});
</script>
Put that on any page or site header and it will add the class to all images. You can modify the search filter to suit.
You might need to re-call your lightbox initialization code too, or put this before it gets called initially.

Magento catalog image change on hover

On the catalog/category page I would like images change when hover. Like clubmonaco.com I know how to do it on html/css but no idea on magento. Any help?
You could modify files in this directory:
app/design/frontend/base/default/template/catalog/product
for example (list/ and list.phtml)
or your template for example:
app/design/frontend/default/yourtemplate/template/directory with product files
CSS files you can find in:
skin/frontend/
You should also think, where the second image is stored. You can use "CSS-Sprites" for this case - a single image file, that contains both photos. The disadvantage is, that you have to customize every page, where magento shows product images.
Alternatively you have to define exact orders. First image is the front view, second image is always the back view.
The programming part is not really difficult. Look at
app/design/frontend/base/default/template/catalog/product/list.phtml
for the Catalog view. Path can vary, if you have a custom template. In the Magento backend there is a feature to show up the real path (system->configuration->development tools).
You can write your Javascript directly into the list.phtml. Magento also writes JS-code directly in the .phtml files. Of course it's not very pretty, but Magento is so complex; if other people work with the shop system, it will be easier to find.
Keep in mind, that the list.phtml contains two layouts: Grid and List View. Just if you do a change and wonder, why you can't see a change in the frontend ;-)

How to return the generated image by phpThumb and not the original one with code appended?

I'm generating images through phpThumb on my Wordpress based website using Magic Fields 2 but I'm having problems posting those images to We Heart It and other websites since they don't recognize it as an image due to all the code appended.
Therefore I was wondering if there's a way to make phpThumb return the actual generated image thumbnail link instead of the original link with all the code appended like:
http://www.mywebsite.com/wp-content/themes/basetheme/phpThumb/phpThumb.php?src=http://www.mywebsite.com/wp-content/files_mf/1331856830IMG_0286.jpg&w=364&h=200&zc=1&q=95
Is there any way to achieve this?

How does one inject variables into page templates from a custom Drupal module?

We've created a custom module for organizing and publishing our newsletter content.
The issue I'm running into now -- and I'm new to theming and Drupal module development, so it could just be a knowledge issue as opposed to a Drupal issue -- is how to get each newsletter themed.
At this point the URL structure of our newsletter will be:
/newsletters/{newsletter-name}/{edition-name}/{issue-date} which means that we can create template files in our theme using filenames like page-newsletters-{newsletter-name}-{edition-name}.tpl.php, which is great. The one issue I'm running into is that all of the content comes through in the $content variable of the theme. I'd like to have it come through as different variables (so that I can, inside the theme, place certain content in certain areas.)
Is there a proper way for doing this?
Edit: To answer some questions: The issue is a node (there are issue, edition and newsletter nodes) and the path is being set using hook_menu with wildcards and a router.
The best answer I could find was to add a check inside of phptemplate_preprocess_page to send the vars back to the module and have them be updated.
Like so:
function phptemplate_preprocess_page(&$vars) {
if (module_exists('test_module')) {
_test_module_injector($vars);
}
}
then in my test_module.module file I created this function:
function _test_module_injector(&$vars) {
$vars[] = call_to_other_functions_to_load_vars();
}
It seemed to work. I wish there was a way to do this without having to touch the theme's template.php file, but otherwise this works well.
If there were better documentation for template preprocess functions, Drupal would be a lot more accessible - as it is, you need to piece together the information from a lot of different explanations. One place to start is here:
http://drupal.org/node/223430
but if you take the time to work through the tutorial below, you'll find you can do most things:
http://11heavens.com/theming-the-contact-form-in-Drupal-6
This is an old post, and the OP's issues seems to have been solved.
However, just for others finding this through Google (or otherwise):
Install the 'Devel' module: http://drupal.org/project/devel
Also the 'Devel Themer' module: http://drupal.org/project/devel_themer
Use Devel Themer to go through the $content variable and find what you need to pull out.
There are a bunch of Devel/Themer docs/tuts out there, but its usage is pretty straightforward. Note, though, that some stuff in there will need to be sanitized before printing in the theme.
The suggestion to show the node as a View and then modifying the view templates sounds pretty crazy, though it'll work.

HTML\rich text in Drupal's node title?

I need the node titles to be able to display some text formatting.
As far as I understand, Drupal's title field is just plain text, it doesn't allow HTML or any other input format. Is that true? Is there a way to override this, or another solution?
I am working with Drupal 6.
You can pretty easily do this in your theme, there are different ways to do with. The simplest would probably to do it in your template.php
/* this function generates the variables that are available in your node.tpl,
* you should already have this in your template.php, but if not create it
*/
function mytheme_preprocess_node(&$vars) {
// It's important to run some kind of filter on the title so users can't
// use fx script tags to inject js or do nasty things.
$vars['title'] = filter_xss($vars['node']->title);
}
What happens in the function is that it overwrites the default value for $title in the node.tpl which holds the variable used for the title. It is usually placed within a h1 or h2 tag, so you should be aware of that. The filter_xss is used to only allow basic html tags, so protect the site, you can look at that function here. That are some other filter functions, like check_markup, and filter_xss_admin, but you can give a second param for filter_xss which is an array of allowed tags, so should the default not be good enough, you can just change it to fit your needs.
Use function mytheme_preprocess_page for D7.
Extending the module mentioned by wiifm, for D7 there is now also: https://drupal.org/project/html_title_trash
It allows more tags and also works for block titles, rather than just node titles.
