<p>With <strong>GIC</strong>, you can display the title, caption, and description image attributes. You can also change/filter the rendering HTML to whatever you want.</p>
<p>After installing and activating GIC, write your filter and add the WordPress <a href="https://codex.wordpress.org/Gallery_Shortcode" rel="nofollow ugc">Gallery shortcode</a> to your page.</p>
<p>If you’ve been <em>dreaming</em> of writing a filter to customise the gallery image captions, then this plugin is for you.</p>
<p><a href="https://streetphotography.blog/gallery-image-captions-demo/" rel="nofollow ugc">Visit the live demo page.</a></p>
<h4>Motivation</h4>
<p>The default WordPress gallery shortcode will only display the <strong>caption</strong> from the media’s attachment metadata. Sometimes it’s nice to display more like the title—even the description.</p>
<p>The <strong>GIC plugin</strong> overrides the WordPress gallery shortcode function to create a <a href="https://developer.wordpress.org/plugins/hooks/" rel="nofollow ugc">hook</a>. With this <em>hook</em> you can do a little bit more than just displaying the caption.</p>
<p>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.</p>
<h3>Usage</h3>
<h4>Custom Filter For Displaying Captions</h4>
<p>The <strong>crux</strong> of this plugin is the ability to filter the gallery image caption. The <code>galimgcaps_gallery_image_caption</code> hook makes this possible.</p>
<p>For the usage examples below, this is the filter used.</p>
<pre><code>/**
 * 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 $my_image_meta array. 
     * You can add your own HTML too.
     */
    return "<{$captiontag} class='wp-caption-text gallery-caption' id='{$selector}-{$id}'>" .
            "Title: " . $my_image_meta['title'] . "<br>" .
            "Caption: " . $my_image_meta['caption'] . "<br>". 
            "Description: ". $my_image_meta['description'] . 
        "</{$captiontag}></{$itemtag}>";

}
add_filter('galimgcaps_gallery_image_caption', 'mlc_gallery_image_caption', 10, 4);
</code></pre>
<p>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 <code>functions.php</code> file. Rename the function and tweak the return string to suit your needs.</p>
<h4>New Filter To Get Custom Fields</h4>
<pre><code>/**
 * 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 $image_meta;
}
add_filter( 'galimgcaps_image_meta', 'gic_add_custom_fields', 10, 2 );
</code></pre>
<p>To use these two custom fields, your <code>galimgcaps_gallery_image_caption</code> would look something like this.</p>
<pre><code>function mlc_gallery_image_caption($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'] ? 
        "<br><strong>Credit</strong>: <a style='display: inline;' href='" . 
        $my_image_meta['credit_link'] . 
        "'>" . $my_image_meta['credit_text'] . "</a>" . "<br>" : 
        '';

    /**
     * With GIC 1.4.0 you can also add custom media attachment fields
     * to your captions.
     */
    return "<{$captiontag} class='wp-caption-text gallery-caption' id='{$selector}-{$id}'>" .
            "<strong>Caption</strong>: " . $my_image_meta['caption'] . "<br>" . 
            $credit .
            "</{$captiontag}></{$itemtag}>";

}
add_filter('galimgcaps_gallery_image_caption', 'mlc_gallery_image_caption', 10, 4);

<p><strong>Since v1.2.0</strong>, GIC automatically adds an <strong>Image ID</strong> column to your WordPress Media Library. This is to help you add the image IDs to your GIC shortcodes.</p>
<p><a href="https://ps.w.org/gallery-image-captions/assets/screenshot-11.png" rel="nofollow ugc">See where GIC automatically adds an Image ID column to your WordPress Media Library.</a></p>
<p><strong>New in v1.4.0</strong>, GIC support custom media attachment fields.</p>
<h3>Usage Example 1</h3>
<h4>Shortcode</h4>
<p>For starters, let’s use a</p>
<pre><code><p></p> 
</code></pre>
<p>tag for the caption tag.</p>
<pre><code>[gallery size="full" columns="1" link="file" ids="114" captiontag="p"]
</code></pre>
<h4>Styling</h4>
<p>Let’s override the generated styles with our own style for one particular image.</p>
<pre><code>/* 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;
}
</code></pre>
<h3>Usage Example 2</h3>
<h4>Shortcode</h4>
<p><strong>A 2 column x 1 row gallery with large size images using an H4 for the caption.</strong></p>
<pre><code>[gallery size="large" columns="2" link="file" ids="109,106" captiontag="h4"]
</code></pre>
<p><strong>A 3 column x 1 row gallery with medium size images using a blockquote for the caption.</strong></p>
<pre><code>[gallery size="medium" columns="3" link="file" ids="109,106,108" captiontag="blockquote"]
</code></pre>
<p>Did you notice that we are using</p>
<pre><code><blockquote></blockquote> 
</code></pre>
<p>in the second shortcode? Let’s give it try just for <em>kicks</em>.</p>
<h4>Styling</h4>
<pre><code>/* 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;
}
</code></pre>
<h3>Responsive CSS Example</h3>
<p>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.</p>
<pre><code>/* 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; 
  }
}
</code></pre>


Gallery Image Captions (GIC)

Gallery Image Captions (GIC) allows you to customise WordPress gallery image captions.

<p>Mammoth is designed to convert .docx documents, such as those created by Microsoft Word, Google Docs and LibreOffice, and convert them to HTML. Mammoth aims to produce simple and clean HTML by using semantic information in the document, and ignoring other details. For instance, Mammoth converts any paragraph with the style <code>Heading1</code> to <code>h1</code> elements, rather than attempting to exactly copy the styling (font, text size, colour, etc.) of the heading. This allows you to paste from Word documents without the usual mess.</p>
<p>There’s a large mismatch between the structure used by .docx and the structure of HTML, meaning that the conversion is unlikely to be perfect for more complicated documents. Mammoth works best if you only use styles to semantically mark up your document.</p>
<p>The following features are currently supported:</p>
<ul>
<li>
<p>Headings.</p>
</li>
<li>
<p>Lists.</p>
</li>
<li>
<p>Tables. The formatting of the table itself, such as borders, is currently ignored, but the formatting of the text is treated the same as in the rest of the document.</p>
</li>
<li>
<p>Footnotes and endnotes.</p>
</li>
<li>
<p>Images.</p>
</li>
<li>
<p>Bold, italics, superscript and subscript.</p>
</li>
<li>
<p>Links.</p>
</li>
<li>
<p>Text boxes. The contents of the text box are treated as a separate paragraph that appears after the paragraph containing the text box.</p>
</li>
</ul>
<h4>Embedded style maps</h4>
<p>By default, Mammoth maps some common .docx styles to HTML elements. For instance, a paragraph with the style name <code>Heading 1</code> is converted to a <code>h1</code> element. If you have a document with your own custom styles, you can use an embedded style map to tell Mammoth how those styles should be mapped. For instance, you could convert paragraphs with the style named <code>WarningHeading</code> to <code>h1</code> elements with <code>class="warning"</code> with the style mapping:</p>
<pre><code>p[style-name='WarningHeading'] => h1.warning:fresh
</code></pre>
<p><a href="http://mike.zwobble.org/projects/mammoth/embed-style-map/" rel="nofollow ugc">An online tool</a> can be used to embed style maps into an existing document. Details of <a href="https://github.com/mwilliamson/mammoth.js#writing-style-maps" rel="nofollow ugc">how to write style maps can be found on the mammoth.js documentation</a>.</p>
<p>A style map to be used for all documents can be set by configuring Mammoth (see below).</p>
<h4>Configuration</h4>
<p>Mammoth can be configured by writing a separate plugin. For instance, <a href="https://github.com/mwilliamson/mammoth-wordpress-plugin/tree/master/examples/options-plugin" rel="nofollow ugc">this example plugin</a> adds a custom style map, and uses a document transform to detect paragraphs of monospace text and converts them to paragraphs with the style “Code Block”.</p>
<p>As a WordPress plugin, Mammoth uses the JavaScript library mammoth.js to convert documents. Mammoth will use the JavaScript global <code>MAMMOTH_OPTIONS</code> whenever calling mammoth.js, which allows for some customisation. <code>MAMMOTH_OPTIONS</code> should be defined as a function that returns an options object. This options object will then be passed in as the <code>options</code> argument to <code>convertToHtml</code>. The <a href="https://github.com/mwilliamson/mammoth.js" rel="nofollow ugc">mammoth.js docs</a> describe the various options available.</p>
<p>The global <code>MAMMOTH_OPTIONS</code> will be called with <code>mammoth</code> as the first argument. This can be useful if you need to use a function from mammoth.js, such as <code>mammoth.transforms.getDescendantsOfType</code>.</p>
