PHP Syntax Error from ExpressionEngine Template

Question

Here's some code I'm using to generate Breadcrumbs on my site. Unfortunately the client has quite specific requirements in terms of URLs, so I've had to play around with Crumbly's tag a little using an If statement:

{if segment_1 == "search"}
    {exp:crumbly:breadcrumbs custom_url:pattern="template_group/template/ignore"}
{if:elseif segment_2 == "search"}
    {exp:crumbly:breadcrumbs}
{if:else}
    {exp:crumbly:breadcrumbs}
{/if}

    {if count > 1}
        {if 1 == 1}
            <span class="divider">&raquo;</span>
            <li>
                <a href="{if count != total_results}{breadcrumb_url}{if:else}#{/if}">
                    {breadcrumb_title}
                </a>
            </li>
        {/if}
    {/if}
{/exp:crumbly:breadcrumbs}

Unfortunately, EE's template, when saved, warns me this:

{exp:crumbly … No closing tag found. Note: some tags do not require closing. Please consult the module's documentation if you experience problems.

However I hope you can see it should just be a warning, as the closing tag is present.

Here's the main problem. When I load the page, I get this:

Parse error: syntax error, unexpected T_ELSEIF in /nfs/c09/h02/mnt/135913/domains/mysite.com/html/system/expressionengine/libraries/Functions.php(683) : eval()'d code on line 75

Any ideas?

Answer 1

For deeper understanding, read about Rendering Stages in EE user guide. Advanced conditionals are processed after module tags.

Putting it simply, exp:crumbly:breadcrumbs is processed before if statements, so EE engine is receiving 3 exp:crumbly:breadcrumbs opening tags and just one closing tag.

There are 2 possible solutions:

1) Have separate code for each if (note that actually 3 tags will be processed, but just 1 displayed)

2) Use IfElse or Switchee module (this is the approach I'd choose)

Answer 2

You can't separate heading and closing tags by {if} statements like that. I've never used Crumbly specifically, but with ExpressionEngine native tags, BOTH the open and closing tags need to be within the `{if} area to be properly evaluated, so this should work

{if segment_1 == "search"}

    {exp:crumbly:breadcrumbs custom_url:pattern="template_group/template/ignore"}
     {if count > 1}
        {if 1 == 1}
            <span class="divider">&raquo;</span>
            <li>
                <a href="{if count != total_results}{breadcrumb_url}{if:else}#{/if}">
                    {breadcrumb_title}
                </a>
            </li>
        {/if}
    {/if}
    {/exp:crumbly:breadcrumbs}

{if:elseif segment_2 == "search"}

    {exp:crumbly:breadcrumbs}
     {if count > 1}
        {if 1 == 1}
            <span class="divider">&raquo;</span>
            <li>
                <a href="{if count != total_results}{breadcrumb_url}{if:else}#{/if}">
                    {breadcrumb_title}
                </a>
            </li>
        {/if}
    {/if}
    {/exp:crumbly:breadcrumbs}

{if:else}

    {exp:crumbly:breadcrumbs}
     {if count > 1}
        {if 1 == 1}
            <span class="divider">&raquo;</span>
            <li>
                <a href="{if count != total_results}{breadcrumb_url}{if:else}#{/if}">
                    {breadcrumb_title}
                </a>
            </li>
        {/if}
    {/if}
    {/exp:crumbly:breadcrumbs}

{/if}

but this WILL NOT

{if segment_1 == "search"}
    {exp:crumbly:breadcrumbs custom_url:pattern="template_group/template/ignore"}
{if:elseif segment_2 == "search"}
    {exp:crumbly:breadcrumbs}
{if:else}
    {exp:crumbly:breadcrumbs}
{/if}

    {if count > 1}
        {if 1 == 1}
            <span class="divider">&raquo;</span>
            <li>
                <a href="{if count != total_results}{breadcrumb_url}{if:else}#{/if}">
                    {breadcrumb_title}
                </a>
            </li>
        {/if}
    {/if}
{/exp:crumbly:breadcrumbs}
