Php – How to assign an array within a smarty template file

PHPsmarty

I was wondering if it was possible to assign an array to a variable within a Smarty template file? I have tried this

{assign var='file' value = array('dir','doc','exe')}

But when I print out the array it produces this:

array(\'dir\',\'doc\',\'exe\')

How can I stop Smarty escaping the array values?

Thanks in advance

{php}
  $this->assign("array", array('dir','doc','exe'));
{/php}

{foreach from=$array item=item}
  {$item}
{/foreach}

From Smarty v.3 new syntax is available

{$array = ['item1','item2',$item3]}

see for more details : http://www.smarty.net/docs/en/language.syntax.variables.tpl

Warning: Cannot modify header information - headers already sent

Happens when your script tries to send an HTTP header to the client but there already was output before, which resulted in headers to be already sent to the client.

This is an E_WARNING and it will not stop the script.

A typical example would be a template file like this:

<html>
    <?php session_start(); ?>
    <head><title>My Page</title>
</html>
...

The session_start() function will try to send headers with the session cookie to the client. But PHP already sent headers when it wrote the <html> element to the output stream. You'd have to move the session_start() to the top.

You can solve this by going through the lines before the code triggering the Warning and check where it outputs. Move any header sending code before that code.

An often overlooked output is new lines after PHP's closing ?>. It is considered a standard practice to omit ?> when it is the last thing in the file. Likewise, another common cause for this warning is when the opening <?php has an empty space, line, or invisible character before it, causing the web server to send the headers and the whitespace/newline thus when PHP starts parsing won't be able to submit any header.

If your file has more than one <?php ... ?> code block in it, you should not have any spaces in between them. (Note: You might have multiple blocks if you had code that was automatically constructed)

Also make sure you don't have any Byte Order Marks in your code, for example when the encoding of the script is UTF-8 with BOM.

Git – One project, Multiple customers with git

In addition to cpharmston's answer, it sounds like you need to do some refactoring to separate out what is truly custom for each client and what isn't. Then you may consider adding additional repositories to track the customizations for each client (entirely new repos, not branches). Then your deployment can pull your "core" from your main repo, and the client-specific stuff from that repo.
