Hi!
I'm new and I've tried to search around the web to learn how to do this in smarty. I want to get all the Emails to be wrote out in one long variable in smarty.
My Smarty Foreach:
Code: Select all
{foreach from=$items item=entry}
All the values for every item.....
{/foreach}
In PHP I would do like this:
Code: Select all
$AllEmail = $AllEmail;
while($row = mysql_fetch_array($result))
{
$AllEmail = $AllEmail . $row['email'].",";
};
Thanks for helping a newbie a this smarty thing!

Okay, I'll try to explain me a little better
:
I use FrontEndUser Listning 0.4-beta-3. I show all the users, with names and email, in a given group in a tabel. After that, I want to make a "Email All users" button. So I was thinking of make a list trough the foreach: email1, email2, email3,... etc. to use for that purpose.
Sorry that I didn't explained that the first time. Make sense?

Okay, the thing I really needs help for, is understanding the syntax of smarty.
In PHP I could do something like this in a loop:
Code: Select all
$allEmail = $allEmail .' + ' . $row['email'];
When the loop is done, I can do echo $allEmail and I'll get a long list of all emails together in one variable

See
http://www.smarty.net/docs/en/language. ... oreach.tpl and
http://www.smarty.net/docs/en/language.modifier.cat.tpl
Code: Select all
{assign var='allemails' value=''}
{foreach from=$yourfulllistofitems item='item'}
{assign var='allemails' value=$allemails|cat:$item.email|cat:';'}
{/foreach}
This will create a var, $allemails, which is a string comprising all the email addresses separated by semi-colons, eg:
"
one@email1.com;
one@email2.com;
one@email3.com;...."

Here is a way to create a new
array rather than a string.
Note that you do not have to create the var first. If it doesn't exist, Smarty will create it on the first iteration.
Code: Select all
{foreach from=$myfulllist item='item'}
{append var='allemails' value=$item.email|cat:';'}
{/foreach}
