Galleries

Galleries Galleries

Image galleries are the best way to showcase your pictures on your WordPress sites. WordPress bundles the Create Gallery feature by default in the media uploader which allows you to create a simple gallery.

Note: Before adding a gallery, you must have images in your media library. Otherwise, you need to upload the images into the library and can proceed on gallery creation.

The Gallery feature allows you to add one or more image galleries to your posts and pages using a simple Shortcode.

The basic form of gallery shortcode is:

[gallery]
Tip:
If you use the [gallery] shortcode without using the ids argument in your post or page, only images that are “attached” to that post or page will be displayed.

If you need to add multiple images with ID’s, use the following sample shortcode

[gallery ids="10, 205, 552, 607"]
//Note: 10, 205, 552 and 607 are the IDs of respected image.

Tip:
NOTE: find the proper IDs of the images for the gallery. Go to Media library and click on the respected image and ID will appear on the URL.

To use the shortcode from the template file, use the do_shortcode() function. Insert the following code into your template file:

echo do_shortcode( [gallery] );

If you need to use the shortcode with IDs, insert the following code in your template file:

echo do_shortcode( [gallery ids="10, 205, 552, 607"] );

Usage Usage

There are may options that may be specified using the below syntax:

[gallery option1="value1" option2="value2"]

If you want to print the gallery directly on the template file, use `do_shortcode()` function like below:

<?php echo do_shortcode('[gallery option1="value1"]'); ?>

If you need to filter the shortcodes, the following example gives you some tips

// Note: 'the_content' filter is used to filter the content of the
// post after it is retrieved from the database and before it is 
// printed to the screen
 <?php $gallery_shortcode = '[gallery id="' . intval( $post->post_parent ) . '"]';
    print apply_filters( 'the_content', $gallery_shortcode );
 ?>

IDs IDs

The IDs option on the gallery shortcode loads images with specific post IDs.

If you want to display the attached image with the specific post ID, follow the following code example.

// Note: remove each space between brackets and 'gallery' and brackets and `123"`.
//Here "123" stands for the post IDs. If you want to display more than
//one ID, separate the IDs by a comma `,`.
[ gallery id="123" ]

Use ‘do_shortcode’ function to print the gallery with IDs on template files like below:

// Note: remove each space between brackets and 'gallery' and brackets and `123"`.
<?php echo do_shortcode(' [ gallery id="123" ] '); ?>
