How can I extract a person’s first name from their screen name? (The screen names are the people’s full names.) This isn’t working either in a snippet or in a template set to PHP on Output:
<?php
$screen_name = '{screen_name}';
$name = explode(" ",$screen_name);
$first_name = $name[0];
?>
Welcome <?php echo $first_name; ?>I just get the full screen name; the PHP doesn’t seem to do anything.

What is your PHP parsing stage set to for the template which this code is on? Try flipping it and see if that helps.
Best wishes,

Switching PHP to parse on Input doesn’t do anything, it still shows the complete screen name.
I put the same code in an embedded template and the behavior is the same.

Hmm odd!
I might be wrong on this but it might be that you need two parsing stages here due to setting the php variable to that of the screen_name and then trying to utilise that variable.
On a quick test I did it shows that outputting the array using var_dump does indeed show that you just get something like this :
array(1) {
[0]=>
string(23) "EE214 Administrator"
}
Welcome EE214 Administrator
Perhaps a plugin might be the way to go here?

I’ll try to do it as a plugin. My first attempt didn’t turn out so good.
class Get_first_name {
var $return_data = '';
function __construct(){
$this->EE =& get_instance();
$screen_name = $this->EE->TMPL->tagdata;
$name = explode(' ',$screen_name);
$first_name = $name[0];
$this->return_data = $first_name;
}
}If I wrap the screen_name in my EE template with {exp:get_first_name} I get a random alphanumeric string. If I wrap the screen_name with {get_first_name} it displays the entire screen_name.
I’ve used CodeIgniter for several years but I haven’t done any EE add-ons yet so I’m sure I’m missing something.

If you just want to use the {screen_name} of the logged in user then you’d probably be best off using :
$screen_name = $this->EE->session->userdata['screen_name'];to get the screen name for use in your function.
Hope that helps a bit.

class Get_first_name {
var $return_data = '';
function __construct(){
$this->EE =& get_instance();
$screen_name = $this->EE->session->userdata['screen_name'];
// $screen_name = $this->EE->TMPL->tagdata;
$name = explode(' ',$screen_name);
$first_name = $name[0];
$this->return_data = $first_name;
}
}Returns this: M00o93H7pQ09L8X1t49cHY01Z5j4TT91fGfr
Changing it to return $screen_name instead of $first_name gives the same result.

No promises but give this a go :

{first_name}{last_name}

// END

{exp:explode_first_name} {first_name}, {last_name} {/exp:explode_first_name}
Will need to go into a file called pi.explode_first_name.php in a folder called explode_first_name like this :
system > expressionengine > third_party > explode_first_name > pi.explode_first_name.php
