conditional content
18 October 2007 at 3:13am Last edited: 18 October 2007 3:17am
hello,
i am attempting to take an existing website and recreate it using silverstripe. i'm relatively new to the programming side of it so this may be a simple problem that im completely overlooking the simple solution to.
i have a StaffPage (same as EmployeePage) which contains a the following:
------
Employee Name
Email: employee_email@whatever.com
<several paragraphs of bio text>
------my StaffPage has input fields for the "Content" (bio text), "Name" and "Email". some of the employees do not have an email address and i would like to make that part of the html conditional based on whether information is in the field
the code for my StaffPage template is:
------------------------
-----------------------<% if Menu(2) %>
<% include Menu3 %>
<% end_if %>
<div id="StaffPhoto">
$Photo.SetWidth(340)
</div>
<h1 id="pagetitle">$Title</h1>
<a href="mailto:$Email">Email: $Email</a>
$Contenti have tried adding:
-----------------------
-----------------------<% if $Email %>
<a href="mailto:$Email">Email: $Email</a>
<% end_if %>
but the syntax there is incorrect and gives an errorcan anyone tell me how to correctly do this? or point me in the right direction? i have tried searching for more help on conditions but couldnt seem to find any in-depth documentation
thanks in advance!

what you have to do is define a function in your pagetype.php file that returns true or false if the email exists for example
function hasEmail() {
if ($this->Email == "") then return false;
else
return true;
}then in the template you call the function <% if hasEmail %>
There might be another way but I have done a similar thing this way and it works.
Regards
Trevor
