Template Tags

The tag pair is how you output Ansel images. Whether you are using the custom field tag within a Channel Entry tag pair, a Grid field tag pair, a Bloqs field tag pair, a Low Variables tag pair, or the stand alone tag pair, usage is almost identical across the tags. In fact, the only real difference is with the stand alone tag pair, which has just a few extra parameters available to it.

{exp:channel:entries channel="my_channel"}
    {!-- Number of images in field --}
    {my_ansel_field count="true"}

    {!-- Check if field has images --}
    {if "{my_ansel_field count='true'}" > 0}
        // Do stuff if field has images
    {/if}

    {!-- Output images --}
    {my_ansel_field}
        {img:url}
    {/my_ansel_field}

    {!-- Output images from a grid field --}
    {grid_field}
        {grid_field:my_ansel_field}
            {img:url}
        {/grid_field:my_ansel_field}
    {/grid_field}

    {!-- Output images from a blocks field --}
    {blocks_field}
        {my_block}
            {my_ansel_block_field}
                {img:url}
            {/my_ansel_block_field}
        {/my_block}
    {/blocks_field}
{/exp:channel:entries}

{!-- Output images from a Low Variables Ansel field --}
{exp:low_variables:pair var="my_ansel_var"}
    {img:url:resize width="500"}
{/exp:low_variables:pair}

{!-- Output images with the stand alone tag --}
{exp:ansel:images content_id="102" field_id="33"}
    {if img:no_results}
        // Do no results markup here
    {/if}
    {img:url:resize width="400"}
{/exp:ansel:images}

Tag Pair Variables

Note all variable examples assume the default namespace of img. Use your custom namespace if you have set the namespace parameter.

These variables are available in the tag pair:

{img:id}
{img:site_id}
{img:content_id}
{img:field_id}
{img:content_type}
{img:row_id}
{img:col_id}
{img:file_id}
{img:original_file_id}
{img:upload_location_id}
{img:filename}
{img:original_filename}
{img:basename}
{img:original_basename}
{img:extension}
{img:original_extension}
{img:filesize}
{img:original_filesize}
{img:width}
{img:height}
{img:title}
{img:caption} <!-- This is the legacy variable, but {img:description} is preferred -->
{img:description} <!-- This is the new variable that replaces caption -->
{img:member_id}
{img:position}
{img:cover}
{img:upload_date}
{img:modify_date}
{img:path}
{img:original_path}
{img:url}
{img:original_url}
{img:thumbnail_path}
{img:thumbnail_url}
{img:index}
{img:count}
{img:total_results}
{img:host}
{img:description_field}
{img:credit_field}
{img:location_field}
{img:original_description_field}
{img:original_credit_field}
{img:original_location_field}

When you have made manipulations available with the parameter manipulations="true", they will be available as follows:

{img:manipulation_name:path}
{img:manipulation_name:url}
{img:manipulation_name:width}
{img:manipulation_name:height}

No Results

If your tag pair has no results, you can use the {if img:no_results} conditional to output content.

On the Fly Cropping and Resizing

Ansel can crop and resize images on the fly. Doing so is very efficient because the cropped/resized image is cached after the first request for it is made. Any request for that cropped/resized image thereafter comes straight from the cache on disk.

Cropping/resizing is available to the {img:url} variable.

width="400"
height="100"
crop="true"
background="d34747"
force_jpg="true"
quality="80"
scale_up="true"
cache_time="86400" // Defaults to forever

{img:url:resize
    width="400"
    height="100"
    crop="true"
    background="d34747"
    force_jpg="true"
    quality="80"
    scale_up="true"
}

Get Total

Sometimes you would like to display the total number of images in a field. Ansel makes this really easy with a parameter on the custom field tag:

{exp:channel:entries channel="my_channel"}
    {my_ansel_field count="true"}
{/exp:channel:entries}
