Hi all!

In template the following not work:

<% if Link == "/" %>

I get the following error when I do http://127.0.0.1/?flush=all:
Parse error: syntax error, unexpected '}' in C:\wamp\www\silverstripe-cache\.cache.themes.mysite.templates.Page.ss on line 406

How should I put this comparison in the template?

Thanks,
Regards,
Jose

You shouldn't make a function in the controller and use that.

Hi Barry!

But, in my Navigation.ss
if I want to do the following:

<ul>
<% control Menu(1) %>
<% if Link == "/" %>
<li><a href="$Link?locale=$locale" title="Go to the $Title.XML page" class="$LinkingMode"><span>$MenuTitle.XML</span></a></li>
<% else %>
<li><a href="$Link" title="Go to the $Title.XML page" class="$LinkingMode"><span>$MenuTitle.XML</span></a></li>
<% end_if %>
<% end_control %>
</ul>

Can't I do this?

How could I do this?

What am I doing wrong?

Thanks Barry!

Jose

Hi Jose,

What you are doing wrong is not reading the documentation, look here:
http://doc.silverstripe.org/sapphire/en/reference/advanced-templates

In the section “If blocks” of this page you’ll find an explanation of how to use those if conditions, that are not as rich as PHP ones, for example: You should not include quotes around the value. Also, / will not work, I guess you should use home:
<% if Link == home %>

Hope it helps,
Juan

Hi Juanitou!

Yes, I read the documentation and I did that test ( <% if Link == home %> ), but it did not work. This condition does not occur, for this reason I tried the other type of condition:
<% if Link == "/" %>

No one of the 2 ways works.

This way ( <% if Link == home %> ) does not produce any errors, but the condition is not true. Why?

I no longer know what to try.

Please some help.

Thanks,
Regards,

Jose

Hi!

Don’t use Link:

<% if URLSegment == home %>

I should have spotted it before, sorry.

Hope it helps,
Juan

Just to be clear... I should have given a slightly longer response...

You shouldn't [use an if for that]

[instead ]make a function in the controller

function LinkIsForwardSlash() {
return ($this->Link() == '/');
}

and use that in the template. You will be able to use exact PHP to solve the problem and Debug::show() will work so you can figure it all out.

Hi Juanitou!

Yes, Yes, Yes!!!! :)
It works!!!
The trick was to use URLSegment. :)

Thank you very much.
