I've been working with WordPress built-in functions for a couple of days now and got everything working this far. However, I am trying to find a solution to only fetch posts that have thumbnails into an array/object.
I have already checked out the Wordpress function references, but have yet not found any solution. How can I achieve this?
The Wordpress codex is pretty sparse on this topic. In WordPress 2.9, "Post Thumbnails" were added. In 3.0, they seem to have been renamed "Featured Images." In your theme, you can easily check to see whether or not a post has a featured image.
Within the main have_posts() loop in your theme, you can:
<?php
if (has_post_thumbnail()) {
/* Post has a thumbnail */
}
?>

I was wondering if someone could help me out. I am developing a theme that uses woocommerce as the ecommerce solution. I know that there are predefined shortcodes that you can use but i was wondering if there was a way to actually implement woocommerce items in my php code as opposed to using shortcodes.
Thanks,
Try this:
https://wordpress.stackexchange.com/a/125286/60175
<?php echo do_shortcode('[product_page id="31"]'); ?>
And at the Shortcodes doc, I see
To find the Product ID, go to the Product > Edit screen and look in the URL for the postid= as shown below.
http://docs.woothemes.com/document/woocommerce-shortcodes/
Of course this still uses shortcodes (pretty slick), but in your PHP. The Wordpress framework must be available in your PHP page, which I think you do by including wp-load.php at the beginning.
I'm developing a plugin that creates custom wordpress pages, however I ran into a problem when trying to get shortcodes from other plugins to integrate into my plugin, well more like I couldn't find any info on it.
For example if someone uses my custom page builder and adds a short code [gallery] that is associated with an enabled plugin, I want the shortcode to do it's thing.
Could anyone point me in the right direction for this?
Try wordpress
http://wordpress.org/plugins/synved-shortcodes/
while this plugin let's you integrate shortcodes on every wordpress page , I suppose that you issue is with wordpress functions.php file where you can have a look at , with this plugin installed !
You can check if a shortcode exist before printing it with the function shortcode_exists() (https://codex.wordpress.org/Function_Reference/shortcode_exists)
Example:
<?php
if ( shortcode_exists( 'gallery' ) ) {
// The [gallery] short code exists.
}
?>
Then, if it exist and you want to print that shortcode with PHP code you should use do_shortcode() function (https://developer.wordpress.org/reference/functions/do_shortcode/)
Example:
<?php echo do_shortcode('[gallery]); ?>
Always use in WordPress's in-built
the_content
hook to print your custom page content.
WordPress by default process all shortcodes before outputting any stuff from this hook.

How to take on a problem in WordPress admin editing.
I'd like to edit an edit-category admin panel to add a featured image to it (just like in posts), but I'm a bit indecisive since a lot of people use a custom field with static path to a photo, but I'm wondering is there a way to do it better(enable some wp hook and such).
Can someone point me in the right direction?
Thanks for the plugin it seems good, but i have one additional problem. It seems i have a lack of knowledge on how to query an object [category] so i can apply filters, hope im making some sense. This is done on my home.php. all dumps are null
<?php get_header();
$listcat = get_categories('hide_empty=0');
foreach($listcat as $x){
$img = apply_filters( 'taxonomy-images-queried-term-image', '');
var_dump($img);
}
get_footer(); ?>
The same code works with no problems if i stick it in category.php. Any ideas? :)
i've used several times the plugin "Taxonomy Images". it works with multi-language wp installs too.

I want to know how to make an archive page like instantshift has made.. link below..
http://www.instantshift.com/archive/
I have made everything but don't know the query to specify the orderly archives listing
I use Viper Bond's Clean Archives for a similar effect: http://www.viper007bond.com/wordpress-plugins/clean-archives-reloaded. I like that the jQuery effect only shows when you activate the plugin in a page.
You could also use <?php wp_get_archives( $args ); ?> as found here: http://codex.wordpress.org/Function_Reference/wp_get_archives
Don't forget to not leave wordpress.stackexchange.com lonely too!
How do I just display the latest post on home (not the whole archive as wp does by default)?
And how can I influence that it has/not date, category, read more, etc?
WP manual does not explain this clearly. Or does it? If yes, please tell me where?
Thank you guys! And girls!
The new Wordpress Themes have child themes, it is a new way to organize and simplify upgrading themes, but it can be a pain because they are not as easy to modify as older themes. Anyway, there is the old way:
You can use the settings in the Administration Page to set your homepage to display only one post (Settings / Reading / Blog pages show at most -> 1 post). But if you want just your home to display one post, and decide you want your archives to display the basic 10 posts, you can edit your theme template to use this function:
<?php query_posts('posts_per_page=1'); ?>
Function Reference/query posts
http://codex.wordpress.org/Function_Reference/query_posts
To be sure no date or category is displayed, you also have to edit the template and remove the corresponding php code (in the loop, you should look for these functions:
<?php the_category(); ?>
<?php the_date(); ?>
Function Reference/the category
http://codex.wordpress.org/Function_Reference/the_category
Function Reference/the date
http://codex.wordpress.org/Function_Reference/the_date
To use the new way, you have to create a child theme to your theme, and override the loop by creating your own loop.
