Assign Wordpress Short code to PHP Variable?

Question

I'm trying to compare a email address held in a PHP variable with a email address held in a short code in Wordpress, this is what I've tried so far:

$email = '[email protected]';
$user_email = do_shortcode('[userinfo field="user_email"]');
echo var_dump(strcmp($user_email, $email) === 0);

But the var_dump always returns false, I'm positive they are the exact same string!

What is the output of var_dump(strcmp($var, $var2)); ? Also Check individual string using var_dump. — Rikesh

@Rikesh When I dump the vars one says string(48) and the other one says string(18), what does that mean? — William L.

@WilliamL.: The shortcode returns something like that: <span class="userinfo">[email protected]</span> (with var_dump you would have seen that). — vstm

@vstm Your right, it does show that! Is there a way to just get the email address? — William L.

By default the userinfo shortcode returns the data wrapped in a <span> tag. To suppress the span tag you can use the nospan-attribute.

The description of the plugin says the following:

[userinfo nospan="true"] should eliminate the surrounding span tag so the output can be used inside URLs or similar applications

So your code should look like that:

$email = '[email protected]';
$user_email = do_shortcode('[userinfo field="user_email" nospan="true"]');
$var = (string) $user_email; // Casts to string
$var2 = (string) $email; // Casts to string
echo var_dump(strcmp($var, $var2) === 0);

You should not use the shortcode for that but just the Wordpress API function to obtain the current users email address:

$email = '[email protected]';

global $user_email;
get_currentuserinfo();

echo var_dump(strcmp($user_email, $email) === 0);

The Worpdress API function get_currentuserinfo() sets the global variable $user_email to the email address of the current user as a string.

See if there are any spaces and if any of the string needs to be trimmed, because if both the strings are same then your code seems to work already.

$email = '[email protected]';
$user_email = '[email protected]';
$var = (string) $user_email; // Casts to string
$var2 = (string) $email; // Casts to string
echo var_dump(strcmp($var, $var2) === 0);

Returns bool(true)

Probably do_shortcode('[userinfo field="user_email"]'); needs to be trimmed. Also you can simply echo $user_email before comparison to see if there is any unexpected value there.

When I dump the vars one says string(48) and the other one says string(18), does this mean I need to trim the strings?

Hanky Panky Over a year ago

yes this means strings are not equal, what does a simple echo suggest? do they look equal? are there any unexpected characters?

William L. Over a year ago

The echo just shows string(48) followed by the email address and string(18) followed by the same email address, its exactly the same.
