If else condition involving contains on url-title?

Question

I have an event block that displays images.

I want to have 3 options: - if event has image, display that image - if event url title has a certain keyword, display that image - else display a placeholder image

I don't know how to write the 2nd option to the existing code:

    {if event_photo}
        {exp:imgsizer:size src="{event_photo}" alt="{title}" width="300" height="450" class="displayBlock" quality="100"}
    {if:else}
        <img src="/images/_pages/_global/placeholder.jpg"/>
    {/if}

Answer 1

You need some RegEx for that.

Using the new conditionals operators of EECMS version 2.9:

{if event_photo}
    {exp:imgsizer:size src="{event_photo}" alt="{title}" width="300" height="450" class="displayBlock" quality="100"}
{if:elseif url_title *= "keyword"}
    {exp:imgsizer:size src="{other_photo}" alt="{title}" width="300" height="450" class="displayBlock" quality="100"}
{if:else}
    <img src="/images/_pages/_global/placeholder.jpg"/>
{/if}

Using switchee, if you can't update EECMS:

{exp:switchee variable="{event_photo}/{url_title}" parse="inward"}
    {!-- if the concatenation of both variables ends on "/", but has something before it --}
    {case value="#./$#"}
        {exp:imgsizer:size src="{event_photo}" alt="{title}" width="300" height="450" class="displayBlock" quality="100"}
    {/case}

    {!-- if there is "keyword" --}
    {case value="#keyword#"}
        {exp:imgsizer:size src="{other_photo}" alt="{title}" width="300" height="450" class="displayBlock" quality="100"}
    {/case}

    {case default="yes"}
        <img src="/images/_pages/_global/placeholder.jpg"/>
    {/case}
{/exp:switchee}
