Hello community...
I am building my blog through your great tutorial !! So far so good...I succeedeed to manage.
BUT...
I can not figure out how to insert the thumbnail of each post inside the post when I go to category page or tag page.
I would also eventually like to have a hook on each image of my posts when I need it...
Where can I get the solution, the tip, the tut may'be....?
Thank you for your help,
Cheers,
one way for sure would be to write your own tag and category loops. for this i usually go into the thematic library folder, extensions, and open up content extensions. find the category loop and copy the function into your functions.php.
//add capability to use WP thumbnails
add_theme_support( 'post-thumbnails' );
//wrap thumbnails w link to post
function my_post_image_html( $html, $post_id, $post_image_id ) {
$html = '<a href="' . get_permalink( $post_id ) . '" title="' . esc_attr( get_post_field( 'post_title', $post_id ) ) . '">' . $html . '</a>';
return $html;
}
add_filter( 'post_thumbnail_html', 'my_post_image_html', 10, 3 );
//remove the current category loop from its hook
function remove_thematic_action() {
remove_action('thematic_categoryloop','thematic_category_loop');
}
add_action('init','remove_thematic_action');
// My New Category Loop
function my_category_loop() {
while (have_posts()) : the_post();
thematic_abovepost(); ?>
<div id="post-<?php the_ID(); ?>" class="<?php thematic_post_class(); ?>">
<?php thematic_postheader(); ?>
//if it has a thumbnail post it here
<div class="thumbnail">
<?php
if ( has_post_thumbnail() ) {
the_post_thumbnail( 'thumbnail' );
} else {
echo '<img src="default-image.png" alt="Example Image" title="Example" />';
} ?>
</div>
<div class="entry-content">
<?php thematic_content(); ?>
</div>
<?php thematic_postfooter(); ?>
</div><!-- .post -->
<?php
thematic_belowpost();
endwhile;
}
add_action('thematic_categoryloop', 'my_category_loop');you can then do a similar thing for all the loops: tag, author, search, etc. download and take a look at Gallery for a good example of custom loops. fair warning... i didn't test this, so there could be a mistake, but it ought to set you in the right direction. i think there is another way you could do this.... by filtering the entry-title i think, maybe someone else will post it and you can choose which you find easier.
see http://justintadlock.com/archives/2009/11/16/everything-you-need-to-know-about-wordpress-2-9s-post-image-feature for more info on thumbnails in WP.

Well...this does not start very well. I do not have any thematic library folder, extensions.
Sometimes I am confused with thematic. I wonder if it the same files as the ones provided in the tutorial or if I should simply have downloaded the thematic at once.
So in the theme tutorial, here is the code for the category :
// For category lists on category archives: Returns other categories except the current one (redundant)
function cats_meow($glue) {
$current_cat = single_cat_title( '', false );
$separator = "\n";
$cats = explode( $separator, get_the_category_list($separator) );
foreach ( $cats as $i => $str ) {
if ( strstr( $str, ">$current_cat<" ) ) {
unset($cats[$i]);
break;
}
}
if ( empty($cats) )
return false;
return trim(join( $glue, $cats ));
} // end cats_meow
add_filter('thematic_postheader_posttitle', 'my_post_title');
How could I work directly from there ?
i swear i posted to this yesterday... akismet must be getting me again.
i have no clue what that function is or is trying to do. but you DO definitely have a content-extensions file in the library folder. it is in Thematic. you should download thematic, unzip it and that way you will have said folder for reference. i look in there all the time. what tutorial are you looking at?
you do not make any edits there however. i usually just copy the functions into my child's functions.php file (and rename them) or sometimes i only need to know the NAME of a certain function, etc.
try pasting my above code into your functions.php file and let me know what happens.

The code above, inserted in functions.php doesnt work fine:
when trying to load the index page it returns this message:
Fatal error: Cannot redeclare my_post_image_html() (previously declared in /docroot/wp/wp-content/plugins/super-post-and-page-plugin/super_page_widget.php:179) in /docroot/wp/wp-content/themes/thematic/functions.php on line 32

Hello Helgatheviking and thanks for keeping up with this...
Well I actually copied your code...but nothing happened.
The tutorial is actually coming from themeshaper.com
I am gonna have to check out thematic....
I wonder if some people from theme shaper sometimes pass by this forum ....
Thank you again anyway a lot for your help :-)
Cheers,
ok i found the other function i was thinking of when replying to another post and then i tweaked it to use myself for thumbnails in excerpts.
add_theme_support( 'post-thumbnails' );
function my_post_image_html( $html, $post_id, $post_image_id ) {
$html = '<div class="thumbnail"><a href="' . get_permalink( $post_id ) . '" title="' . esc_attr( get_post_field( 'post_title', $post_id ) ) . '">' . $html . '</a></div>';
return $html;
}
add_filter( 'post_thumbnail_html', 'my_post_image_html', 10, 3 );
// modify excerpts
// add read more links to everything, add thumbnails and wrap excerpt in p tag
function all_excerpts_get_more_link($post_excerpt) {
if ( has_post_thumbnail() ) {
$child_excerpt = the_post_thumbnail( 'thumbnail' ) . '<p>' . $post_excerpt . '</p>' . '<p class="readmore"><a href="'. get_permalink($post->ID) . '">' . 'Continue Reading »' . '</a></p>';
}
else {
$child_excerpt = '<p>' . $post_excerpt . '</p>' . '<p class="readmore"><a href="'. get_permalink($post->ID) . '">' . 'Continue Reading »' . '</a></p>';
}
return $child_excerpt;
}
add_filter('wp_trim_excerpt', 'all_excerpts_get_more_link');this should work everywhere the theme uses excerpts. if you only want thumbnails on certain sections would need to add some more conditional logic. hope this helps.

Hello Helgatheviking !
Here am I again after so long...
I spent it trying to solve this, changed framework, came back, changed again...to finally install Thematic.
So I followed again your posts , now that I have the same files.
So far, I went into the thematic library folder, extensions, and open up content extensions. Indeed I found this time the category loop and copied the function into my functions.php as followed :
// The Loop
function thematic_categoryloop() {
do_action('thematic_categoryloop');
} // end thematic_categoryloop
My functions.php file looks like this now :
<?php
// Getting Theme and Child Theme Data
// Credits: Joern Kretzschmar
$themeData = get_theme_data(TEMPLATEPATH . '/style.css');
$version = trim($themeData['Version']);
if(!$version)
$version = "unknown";
$ct=get_theme_data(STYLESHEETPATH . '/style.css');
$templateversion = trim($ct['Version']);
if(!$templateversion)
$templateversion = "unknown";
// set theme constants
define('THEMENAME', $themeData['Title']);
define('THEMEAUTHOR', $themeData['Author']);
define('THEMEURI', $themeData['URI']);
define('THEMATICVERSION', $version);
// set child theme constants
define('TEMPLATENAME', $ct['Title']);
define('TEMPLATEAUTHOR', $ct['Author']);
define('TEMPLATEURI', $ct['URI']);
define('TEMPLATEVERSION', $templateversion);
// load jQuery
wp_enqueue_script('jquery');
// Path constants
define('THEMELIB', TEMPLATEPATH . '/library');
// Create Theme Options Page
require_once(THEMELIB . '/extensions/theme-options.php');
// Load legacy functions
require_once(THEMELIB . '/legacy/deprecated.php');
// Load widgets
require_once(THEMELIB . '/extensions/widgets.php');

// Load custom footer hooks

// Add Dynamic Contextual Semantic Classes

// Need a little help from our helper functions
require_once(THEMELIB . '/extensions/helpers.php');
// Load shortcodes
require_once(THEMELIB . '/extensions/shortcodes.php');
// Adds filters for the description/meta content in archives.php
add_filter( 'archive_meta', 'wptexturize' );
add_filter( 'archive_meta', 'convert_smilies' );
add_filter( 'archive_meta', 'convert_chars' );
add_filter( 'archive_meta', 'wpautop' );
// Remove the WordPress Generator – via http://blog.ftwr.co.uk/archives/2007/10/06/improving-the-wordpress-generator/
function thematic_remove_generators() { return ''; }
if (apply_filters('thematic_hide_generators', TRUE)) {
add_filter('the_generator','thematic_remove_generators');
}
// The Loop I JUST ADDED FROM THE EXTENSIONS
function thematic_categoryloop() {
do_action('thematic_categoryloop');
} // end thematic_categoryloop
// Translate, if applicable
load_theme_textdomain('thematic', THEMELIB . '/languages');
$locale = get_locale();
$locale_file = THEMELIB . "/languages/$locale.php";
if ( is_readable($locale_file) )
require_once($locale_file);
?>
Next step would be to add the following code ??
add_theme_support( 'post-thumbnails' );
function my_post_image_html( $html, $post_id, $post_image_id ) {
$html = '<div class="thumbnail">' . $html . '</div>';
return $html;
}
add_filter( 'post_thumbnail_html', 'my_post_image_html', 10, 3 );
// modify excerpts
// add read more links to everything, add thumbnails and wrap excerpt in p tag
function all_excerpts_get_more_link($post_excerpt) {
if ( has_post_thumbnail() ) {
$child_excerpt = the_post_thumbnail( 'thumbnail' ) . '<p>' . $post_excerpt . '</p>' . '<p class="readmore">ID) . '">' . 'Continue Reading »' . '</p>';
}
else {
$child_excerpt = '<p>' . $post_excerpt . '</p>' . '<p class="readmore">ID) . '">' . 'Continue Reading »' . '</p>';
}
return $child_excerpt;
}
add_filter('wp_trim_excerpt', 'all_excerpts_get_more_link');
so doe that work? also, i don't think you need any/all of the following code, unless you've made some modifications that I can't see. Thematic will do all that automatically without the need for you to paste it into your functions file.
// Getting Theme and Child Theme Data
// Credits: Joern Kretzschmar
$themeData = get_theme_data(TEMPLATEPATH . '/style.css');
$version = trim($themeData['Version']);
if(!$version)
$version = "unknown";
$ct=get_theme_data(STYLESHEETPATH . '/style.css');
$templateversion = trim($ct['Version']);
if(!$templateversion)
$templateversion = "unknown";
// set theme constants

define('THEMEURI', $themeData['URI']);
define('THEMATICVERSION', $version);

Hi !
No it does not work
But I just guessed ( beginners always take a tremendous time to get it I guess ??!!) that I might have modified the wrong functions.php
The one above is the functions.php located in the Thematic folder, and does not look like functions.php I am used to see bbtw.
So I discovered that I need to modify the functions.php located in thematic/thematicsamplechildtheme/functions.php
I think all my problems came from this...I am gonna try again
