Core Framework vs Gallery Image Captions (GIC)

Core Framework is a visual CSS framework and design-token builder. Define colors, typography, spacing, layouts, components, utility classes, and custom styles in one project, then generate the CSS used by your WordPress site. The plugin and all included integrations are free and open source. There is no license activation and no paid feature gate. Features Visual framework and design-token editor Fluid typography and spacing scales Color shade and tint generation Utility classes, components, layouts, and custom stylesheets Project import and export Gutenberg integration Bricks integration Oxygen integration Figma synchronization Integrations Enable the integrations you use from Core Framework → Add-ons. Gutenberg, Bricks, Oxygen, and Figma support are included with the plugin; they are not separate paid add-ons. Marketplace The Core Framework Marketplace sells optional design kits and packs. Those content products are separate from the plugin and are not required to use any Core Framework feature or integration. External services Core Framework works without a Core Framework account or hosted Core Framework backend. It makes an external request only when an administrator explicitly asks for one: The bundled font catalog is local. Selecting or previewing a Google Font requests CSS from https://fonts.googleapis.com. Importing it also downloads font files from https://fonts.gstatic.com, after which WordPress serves the saved font files locally. Requests identify the selected font family and variants; as with any web request, Google receives connection information such as the site’s IP address and user agent. No Google API key or Google account is required. Google Terms of Service: https://policies.google.com/terms Google Privacy Policy: https://policies.google.com/privacy Direct Figma-to-WordPress synchronization connects the Figma plugin directly to the user’s own WordPress site using a connection key created by a site administrator. Project data is not routed through Core Framework servers. Remote project import is optional and runs only when an administrator pastes a shareable project link or project ID and submits it. WordPress then requests that project from https://us-central1-core-framework-6bdc9.cloudfunctions.net/getPreset. The request is made by the server rather than the browser, sends no credentials, and the endpoint is read-only: it returns a project only when its owner has marked it as public. Nothing is sent unless an administrator submits a link, and no account is required to import one. Apart from the requests listed above, the plugin’s administration interface, image previews, project storage, CSS generation, and included integrations do not load assets from Core Framework servers. Core Framework does not contact a licensing server and does not require account activation. Licensing Core Framework’s original source code is licensed under the MIT License. Bundled dependencies retain their own open-source licenses. The release archive includes third-party-notices.txt for adapted source and artwork and third-party-licenses.txt for the complete production dependency inventory.

With GIC, you can display the title, caption, and description image attributes. You can also change/filter the rendering HTML to whatever you want. After installing and activating GIC, write your filter and add the WordPress Gallery shortcode to your page. If you’ve been dreaming of writing a filter to customise the gallery image captions, then this plugin is for you. Visit the live demo page. Motivation The default WordPress gallery shortcode will only display the caption from the media’s attachment metadata. Sometimes it’s nice to display more like the title—even the description. The GIC plugin overrides the WordPress gallery shortcode function to create a hook. With this hook you can do a little bit more than just displaying the caption. Some premium themes hide the caption completely. This leaves photography lovers like me scratching their head and spending precious time cobbling together makeshift caption blocks. Usage Custom Filter For Displaying Captions The crux of this plugin is the ability to filter the gallery image caption. The galimgcaps_gallery_image_caption hook makes this possible. For the usage examples below, this is the filter used. /** * Custom Filter for Gallery Image Captions * * Note: Avoid altering captiontag, selector, and itemtag. */ function mlc_gallery_image_caption($attachment_id, $captiontag, $selector, $itemtag) { $id = $attachment_id; // Grab the meta from the GIC plugin. $my_image_meta = galimgcaps_get_image_meta($id); /** * Here's where to customise the caption content. * * This example uses the meta title, caption, and description. * * You can display any value from the $my_image_meta array. * You can add your own HTML too. */ return " " . "Title: " . $my_image_meta['title'] . " " . "Caption: " . $my_image_meta['caption'] . " ". "Description: ". $my_image_meta['description'] . " "; } add_filter('galimgcaps_gallery_image_caption', 'mlc_gallery_image_caption', 10, 4); Feel free to use this filter code as a starter template. After activating the GIC plugin, add the code above to your child theme’s functions.php file. Rename the function and tweak the return string to suit your needs. New Filter To Get Custom Fields /** * New GIC 1.4.0 filter for custom meta fields. */ function gic_add_custom_fields( $image_meta, $attachment ) { // This is how you add a custom fields to the array that // GIC uses to display captions. $image_meta['credit_text'] = $attachment->credit_text; $image_meta['credit_link'] = $attachment->credit_link; return $image_meta; } add_filter( 'galimgcaps_image_meta', 'gic_add_custom_fields', 10, 2 ); To use these two custom fields, your galimgcaps_gallery_image_caption would look something like this. function mlc_gallery_image_caption($attachment_id, $captiontag, $selector, $itemtag) { $id = $attachment_id; // Grab the meta from the GIC plugin. $my_image_meta = galimgcaps_get_image_meta($id); // If there's credit, give it where it's due complete with link. $credit = $my_image_meta['description'] ? " Credit : " . $my_image_meta['credit_text'] . " " . " " : ''; /** * With GIC 1.4.0 you can also add custom media attachment fields * to your captions. */ return " " . " Caption : " . $my_image_meta['caption'] . " " . $credit . " "; } add_filter('galimgcaps_gallery_image_caption', 'mlc_gallery_image_caption', 10, 4); Since v1.2.0, GIC automatically adds an Image ID column to your WordPress Media Library. This is to help you add the image IDs to your GIC shortcodes. See where GIC automatically adds an Image ID column to your WordPress Media Library. New in v1.4.0, GIC support custom media attachment fields. Usage Example 1 Shortcode For starters, let’s use a tag for the caption tag. [gallery size="full" columns="1" link="file" ids="114" captiontag="p"] Styling Let’s override the generated styles with our own style for one particular image. /* Targeting a Specific Image */ /* Add some padding all around. */ #gallery-1 .gallery-item, #gallery-1 .gallery-item p { padding: 1%; } /* Add some moody background with typewriter font. */ #gallery-1 .gallery-item { color: whitesmoke; background-color: black; font-size: 1.25rem; font-family: Courier, monospace; text-align: left !important; } Usage Example 2 Shortcode A 2 column x 1 row gallery with large size images using an H4 for the caption. [gallery size="large" columns="2" link="file" ids="109,106" captiontag="h4"] A 3 column x 1 row gallery with medium size images using a blockquote for the caption. [gallery size="medium" columns="3" link="file" ids="109,106,108" captiontag="blockquote"] Did you notice that we are using in the second shortcode? Let’s give it try just for kicks. Styling /* 1. Style the H4 Used in the Caption Example */ h4 { color: #777777 !important; font-size: 1.2rem !important; font-family: Helvetica, Arial, sans-serif !important; } /* 2. Help Align the Blockquote */ #gallery-3 .gallery-caption { margin-left: 40px !important; } Responsive CSS Example I recommend adding the following media queries if you use galleries with more than one image. The two media queries below will stack 2×1 and 3×1 galleries into a 1 column x n rows or 2 column x n rows as needed. /* Media Queries for Responsive Galleries */ /** * Styling based on article "How To: Style Your WordPress Gallery" * by Par Nicolas. * * https://theme.fm/how-to-style-your-wordpress-gallery/ */ /* Mobile Portrait Breakpoint - 1 column */ @media only screen and (max-width: 719.998px) { .gallery-columns-2 .gallery-item, .gallery-columns-3 .gallery-item { width: 100% !important; } } /* Mobile Landscape and Tablet Breakpoints - 2 columns */ @media only screen and (min-width: 720px) and (max-width: 1024px) { .gallery-columns-3 .gallery-item { width: 50% !important; } }
