use wp_handle_upload to upload the file, wp_insert_attachment to attach it to a post, and add post meta to the post under the key _thumbnail_id to make that attachment a featured image.
I have managed to work it out – the function was leading to a lot of queries, so I rewrote it as follows: $housePhotos = get_post_custom_values(‘house_photos’); $housePhotos = explode(‘;’,$housePhotos[0]); preg_match_all(‘`”([^”]*)”`’, $housePhotos[1], $results); $imageURL = wp_get_attachment_image_src( $results[1][0], ‘house_search’ ); if (!empty($results[1][0])) { echo ‘<img src=”‘ . $imageURL[0] .'” alt=”” />’; }
You need to echo your wp_get_attachment_image, BUT since this function returns a HTML object in the form of, <img src=”https://wordpress.stackexchange.com/questions/67508/path/to/image.jpg”/> It’s not going to work because you are are trying to return this function withing the href attribute of an anchor <a> This is wrong, <a href=”https://wordpress.stackexchange.com/questions/67508/<?= wp_get_attachment_image( $attachment->ID,”blog-thumb’); ?>”></a> This is right, <a href=”https://wordpress.stackexchange.com/questions/67508/<?php … Read more
WordPress will never use single.php to render the site front page. Refer to the Template Hierarchy for Site Front Page: front-page.php Static page hierarchy: $custom-template.php, page-$slug.php, page.php Blog posts index hierarchy: home.php index.php Ensure that you are calling body_class() inside of the HTML <body> tag, and provide a live link to your site, and we … Read more
There is no solution for this as of WP 3.5. There are a couple of core tickets about introducing the ability defer the generation of specific images sizes on the fly rather than at upload time to prevent the generation of multiple images that will never be used. However, they are far from being included … Read more
This is not possible in NextGen gallery. You have to upload the image into each folder, as NextGen gallery works with file structures, not with database entries for retrieving the images.
Thumbnail functions accept a size parameter, the original size can be accessed via full : the_post_thumbnail(‘full’);
I figured it out!! My final code looks like: <?php $images = intval($wpdb->get_var(“SELECT COUNT(*) FROM $wpdb->nggpictures”)); $ngg_options = nggGallery::get_option(“ngg_options”); $maxElement = $ngg_options[“galImages”]; if ($images > $maxElement) { echo “duck”; } ?> Basically the code checks see if the number of images IS larger than the number of images displayed per page…if it is larger I … Read more
It sounds like “Featured” or “Thumbnail” images would work. These are enabled by default for ‘posts’. For ‘pages’ they need to be enabled, but that is as simple as adding add_post_type_support( ‘page’, ‘thumbnail’ ); to your theme’s functions.php hooked on init, and, of course, modifying the theme template files to display the featured image. function … Read more
By default, WordPress will automatically generate a few different sizes of images. You can adjust the sizes here: Dashboard -> Settings -> Media -> Image Sizes. If you want to prevent certain image sizes from generating upon your uploaded images, you could use the filter intermediate_image_sizes to remove the generation of certain image sizes.
