My examples might’ve been unclear about the need to make sure you call the function within the php tags, like so:

<php the_category_image(', '); ?>

I just updated the examples above to make that explicit. Just bringing that up to rule it out as the problem…

Later…
Ah, I just followed the link to your site and saw that you figured out the problem. I completely neglected to mention that the images needed to have the nice-name version of the category name (I now explain it above.) Sorry for the lack of documentation on that.

BTW, I like your use of the plugin!

At the risk of looking like an even bigger idiot, I have another question.
Okay the plugin was installed and working great, but then I had to create a new category. I created it, posted in it, added a new image for it but nothing turns up. I tried reposting again in it after the image was in there. Tried removing that category and putting it back. Also tried deactivating the plugin and then reactivating it. Everything and I still got nothing. I only got listed the other category of the post. Any clue as to what’s going on and how I can fix it? Thanks

Okay well - it’s not anything wierd, as a category. It’s just Books, and the image is Books.png. I have a couple of subcategories, but I have not used them yet and they are not connected to this new category. So I don’t think I did anything wierd. I did what you said with the text names and I get those names okay, both categories.
Blah… lol confusselled.

Well, no that was not the problem, but I finally figured it out. And now I feel like a real dumb@$$. LOL. *Too embarrassed*

1) Yep
2) Done, fine
3) Uploaded, lowercase, cat name OK, good
4) What? “Modify your index.php …” What am I adding to the index file?

These instructions don’t make it clear … so, er, help?

Ah, I see Scott, I just didn’t get that from following the instructions; please add a line in saying this so others don’t try your plugin and just wander off wondering what to do. Thanks for the prompt assistance!

Now on to the tweaking my index file … where did I place the hammer …

I can’t seem to reach your site. My first theory about the category images not showing would be: have you given the category image files the “nice-name” of the category names? For instance, if your category is “Family News!”, the file would be family-news.png (the filenames must be ONLY alphanumeric characters, all lowercased — no punctuation; spaces replaced with “-”).

sorry… more like slashdot.

yeah any advice would be super helpful… I don’t know much about CSS… Did you find anything?

Questions?: The CSS turns out to be pretty simple. After looking at the page you sent me, it looks as though you have something like this in your index.php:

<div class="storycontent">
  <div p align="right"><?php the_category_image(' '); ?></div>
  <?php the_content(); ?>
</div>

(granted, you may have supplied arguments to the_category_image()).

All you need is for it to look like this:

<div class="storycontent">
  <?php the_category_image(' '); ?>
  <?php the_content(); ?>
</div>

But in addition, you need to add this to your CSS file (most likely wp-layout.css):

.catimage {
  float:right;
}

If you want a bit of space around the image, add in something like margin: 2px; to that CSS block.

Scott, when trying to validate the HTML it get the recurring error

document type does not allow element “ul” here; missing one of “object”, “applet”, “map”, “iframe”, “button”, “ins”, “del” start-tag

..."><span class="catBut"><ul class="post-categories">

If I understand correctly an block-level element like

<ul>

<span>

Thanks

Jean-Pascal:

Have you defined the first argument to the function? If you don’t, the function will automatically format using <ul>. You can specify something simple, like a single-quoted space as the first argument (the $seperator) :

<?php c2c_the_category_image(' '); ?>

(I’m using the new function name there, but the way the arguments work is the same with the version of the plugin you have.)

[…] ged a few things around to make it more like what I wanted. If you’ve got WordPress, go to Scott Reilly’s site and get

it didnt add my code sooo uhhhh …
<?php c2c_the_category_image(', ', '', 'png', '/wp-images/categories/'); ?>

Plugin updated to v0.92

This release fixes a pair of typos that prevented properly referenced images from appearing on a site.

This should fix your problem, BoBB.

I may have missed it, but if I have only an image for one of the categories where a post has multiple categories, is there a way to display the other category names after that image in text form?

I really like this plug-in, and it’s relatively simple to implement. I have been having a slight problem with it, although it’s more an annoyance than a problem. Whenever I edit a category, or create a new one and click the “add category” button, it brings me to an error page which says this…

Warning: Cannot modify header information - headers already sent by (output started at /home/.odelia/lotraimant/greenkri.com/blog/wp-content/plugins/category-images.php:152) in /home/.odelia/lotraimant/greenkri.com/blog/wp-admin/categories.php on line 134

I tried returning to my wp-admin, and the changes had been implemented with no problem. It’s just annoying to be hit with that error message every time, then having to return to my wp-admin. Does that make sense?

Kristen: That error is common when there are spaces and/or other characters in the file before the <?php that should mark the very beginning of the code, and/or after the ?> that marks the very end of the code. Check out the category-images.php file and make sure there aren’t those spaces. If you continue to get the error try extracting the plugin file from the .zip.

Doesn’t work on PHP 5.

Followed the directions for installation in WP 1.5, engaged, pasted the function, uploaded the images, added the CSS…works as promised.

Works like a charm, though I had to do a little hacking (I added an align=left to the img production code to get it inline with mytitle the way I wanted.)

One question, though. If you go to my site, you’ll see that the title text says “View all posts in Comics” but clicking doesn’t actually do that, since it seems to have cat=0 in the URI. My site is WP1.5 Strayhorn, is that the reason? Any suggestions on how to get it to do the right thing?

Thanks!
Dave

[…] ss. Also many thanks to the folks who tested out comment stuff, critiqued design, and to this guy for his Category Images plugin that got me my topc icons back! […]

All the category links are “cat=0″ even though the link title shows correctly, e.g. I have more than 1 categories. Nothing unusual on the installation — ISP hosted on PHP 4.3.10, WP 1.5 S. I have the call just after:

In my index.php default theme. The call is:

Aesthetically I am very happy with this plugin! Would love to resolve this little bug.

Hey Scott, just wanted to confirm the above (ie all categories go to 0). The thing is I’m not having that problem on my local server, which is running on a beta of WP1.5 but a pretty recent beta, my normal site is running the stable release.

Seriously thanks for all your work for the plugins you’ve done, brilliant work on all fronts.

I think that WordPress 1.5 changed underneath you, and left this version of the plugin (0.92) slightly broken.

The category ID generated in the links is always zero.

I think this is because the get_category_link() function changed; all the old code I’ve seen uses three parameters - a zero, the category ID, and the “nice name”.

The new version from WP 1.5 appears to only use the category ID.

Thus, all the links wind up as cat=0.

It’s an easy tweak, I think. After having made it, the category IDs on my page work properly in WordPress 1.5.

(Mind you, I’ve only been using Word Press since 1.5, and only for about a week, so I may be wrong… but the code itself was pretty clear.)

Glad to have helped, Scott. It’s a neat plugin.

Darn those moving targets, anyway! =)

I do think that the code is a little messed up when it comes to using the “parent” option. It works fine if it’s blank or caught by the “default” value, but if you try and use “single” or “multiple” then the output is fairly strange.

Have you had a chance to look at this, or would you like me to have a longer (more than reading through the code) look at it?

At the moment, I’m using ” on my site, and then also using the text-based category function to get the other display, so it isn’t a problem for me, but it might be for others.

I’d be happy to have a look at it.

Didn’t mess with it much but it keeps giving me T_Variable errors. I don’t know much php but I’ll learn what I need to. Thanks a million for the tip, I appreciate it. Awesome plugins man. How would one learn to write plugins? Learn the API? Just curious.

I’m going to hate myself for asking this I’m sure, but I’m not getting the output I expect. I see the images, and there is a link, BUT all the links, no matter what image (category) are to http://www.clarkburbidge.com/index.php/archives/category/. The pertinant part linking you to that actual category is missing. Please break it to me softly. I have a feeling it’s right under my nose.

I would also like to have the code post a top image and a bottom image for rollover purposes. Anyone got any ideas of how I’d tweak the plugin to do so..?

I guess I don’t hate myself. The version for WP 1.5 on 3.25.05 fixed my problem. The generated links now connect to the right category instead of just http://www.clarkburbidge.com/index.php/archives/category/. Thanks! Now if you could just fix my CSS.

why mine its not working??

I’m searching for the same like Scott…Category images in the Sidebar…is ther any other plugin?

I found the fix. Just replace category_id with cat_ID throughout.

What is the feck’n deal with your boxes man.. how are w supposed to copy any of your examples from the web page???

Crazy.

I’m getting an error that is confusing the hell out of me.

Parse error: parse error, unexpected T_STRING, expecting ‘&’ or T_VARIABLE or T_CONST in /home/virtual/site121/fst/var/www/html/rantfarm.net/blog/wp-admin/admin-functions.php on line 56

I was able to have the category text and the image appear at the same time but for some reason, i removed that code and now i’m stuck. I want to have both category title and image appear at the same time. can someone please help?

I’m not a php coder, so I don’t know if I’m asking for something difficult, but would it be possible to set this to allow for different images in different themes? I think all you’d have to do would be change the default to look for a catimages directory in the active theme directory, but I suppose I’m not really certain that’s the case.

Well, I followed the instructions, named all the files correctly, and the only place I could find the_category() was in wp.php, so I changed it there. Unfortunately, the category images are not being shown still in 1.5.1.

I can’t think of anything. Anyone have any ideas?

I’m trying to get this to work, but nothing is happening. Can one of you techie people please post a simple example in plain english and maybe provide some sample files. All of this back and forth with broken code is causing my eyes to cross…

yeah i get the same problem as jors

I’cant find get_category within index.php but wp.php

oooops..

with my current theme i cant find “the_category” tag within “index.php

just like jors said

Cool, got it working now! Very nice. Would be nice to get the parent option working. I’ve got one sub-category that I would like to have inherit the category image from its parent.

Pretty cool stuff.

Hello! Excellent plugin, Scott. I’ve added a function to your plugin on my site that allows the category list on the siderbar to display the category pictures instead of the category names. To do this to your own, copy the list_cats() function from template-functions-category.php and paste it into the category-images.php file, renaming it list_cats_with_images(). Call that function in sidebar.php with the same arguments as list_cats() to test if you’ve overridden it correctly. Now, replace these lines in your new list_cats_with_images() function:

$link .= ‘>’;
$link .= apply_filters(’list_cats’, $category->cat_name, $category).’‘;

With these lines:

$link .= ‘>’;
$link .= ‘‘;

That will make images appear instead of the category names! I have made my category images with the text of the category in the picture, so it’s still obvious what category it is. See the sidebar at my website at http://sandstone.brewsters.net for an example of this.

Note that we removed the apply_filters function - I don’t have any idea what this does. Also, I haven’t tested the function with any other arguments other than the WP 1.5.1.3 default, so please post here if you find that this change/addition breaks other argument sets. Thanks again, Scott!

Holy cow this site keeps ganking the code I’m trying to paste…. probably because it contains php functions and HTML tags - even in a [code] tag.

You can download a .txt file with the required code changes here:

Scott: Feel free to edit my comments into a single one with the code correctly displayed.

Hi, I just can’t seem to ge htis working… I am noew to all of this (PHP, CMS, etc). but not to CSS & web dev. SO, any hints on what I may be doing wrong?

I have created a directory for wp-content/images/ and placed 2 test images there (both nice-named versions of categories with posts). I enabled the plug-in; I enabled .gif as a selector.

I refresh & all that happens is that the existing category/link dissppears. No graphics. Any hints for a new user?

sorry forgot..
How can any one talk about the index.php?
And that the little piece of code should be placed in there?
What a bull!

my bad. its working fine with the latest version of the plugin, i had uploaded the old file…

[…] Wow, my first wordpress hack. Thanks has to be given to sandstone for his advice on getting the excellent plug-in “Category image” developed by Scott Reilly to add images to the sidebar instead of the default text. Also, for some good advice on using CSS to give the page the drop-cap look. […]

Hi

Great plugin. If I want the category name to display if there is no graphic plug in, where do I make the modification. In the index.php page or in the plug-in.php page. I want the it to be “true”.

$use_name_if_no_image: (optional) if no image for a category is found, should the name be shown instead?; default is ‘false

Here is where I am using it, as an admin-controlled rating system. The stars are your plugin.

thanks for this plugin, I was looking for something like it all over the web! just a small remark: you’re using an ul element to concatenate one or more icons in one list, but it’s not mentioned in the how-to. not being very experienced with wordpress, I was a bit distressed to find the list bullet. I ended up replacing the list elements with just a span. Looks great with the crystal icons by everaldo!

Hi. I am new. I have installed and activated the plugin.

However my index.php does NOT contain any the_category() entries. How do I proceed?
Sorry for the silly question.

I use the plugin, and it works fine, but it doesnt work, if a category has no posts itself, but some filled subcategories. How do I have to call the c2c_the_category_image function to get an image for “emtpy” categories anyway?

Scratch that, I’ve worked out you stick it in the theme index.php, however no image shows: I have used the nicename for the category (general) and I’ve put it in the right folder (wp-content/images) and placed in the code

But no image appears.

I have WP 1.52. I think there needs to be an update…it would be really appreciated!

Plugins

Yet more work behind the scenes, I’m adding some WordPress Plugins so expect some strange site behaviour. Like zebras and spacehoppers, nothing working and screens of code. Sorry but I apply changes to the live site to see what happens, it’…

How does it work? Where do I specify the image? I dont see any place in the backend to associate an image with a category. Please help.

I’m not getting the links to come through with the images since WP 2.0. Each image has the link “http://www.clarkburbidge.com/index.php/archives/category/” when there should be the category name after the last “/”. Has anyone else seen this?

I’ve installed the plugin- I’m using wordpress 2 - but I cannot get this to work for me.

I have a category called stories and an image called stories.gif. I am calling the function . I have defined the path in the php file itself.

What am I doing wrong? Any guesses???

thanks so much for your help.

ughhh… I did it again!
I am simply calling c2c_the_category_image(’ ‘) .

[…] Add in the Category Image plug in to this blog. […]

You should really make it more obvious that the edit needs to be done to the template not the actual index.php in the root. Took me a few minutes, err more like 30, to figure it out. I’m a dummy.

Other then that I LOVE IT! Thank you ^_^

Just started WPress. Hey, is there a link to an “idiots” guide to using your plug-in? In your installation instructions it ends at copying the php into my root directory. I’m using a custom theme. I just want to hack this in. On which existing php (like style.php etc) do you I use to “call” the function. As you can tell I’m really green and basically have no clue. Any resources would be great. Thanks!

Thanx for that nice plugin.

[…] One of the reasons for not posting to my (old) blog for so long was that iBlog became so unreliable that I was afraid another post would further corrupt its database. I finally decided that the only way to save this blog from oblivion was to reactivate it and put it at a place that I trust (Dreamhost) using commonly used software (Wordpress). I thought about using iWeb but couldn’t find anything that would help me converting iBlog entries to iWeb. Instead my search uncovered Agitprop which converted my iBlog entries to the Movable Type import file format which I then imported into my freshly installed Wordpress (Dreamhost’s 1-click installation rocks!). Agitprop refused to convert my image links into proper URLs (the URL field in Option had no effect and the URLs where missing one of the initial “//”) but a quick use of vi fixed that problem. The formatting is still not where I want it to be but this will have to wait. With coffee2code’s plugin I even got to incorporate category images. […]

Hi! I love this plugin (congrats!) and I’d like to know if it will work fine with WordPress 2.1…
Tks!

It does not appear to work with WP 2.1.

I used this with WordPress 1.5, and 2.0. When I upgraded to 2.1, if I enabled the plugin all I got was blank pages, or pages of junk.

I don’t know what’s going on, or how to debug it right now. I’d be happy to help if I knew how.
