Question

I´ve got a button and a in it variable from my CMS:

<a href="mailto:<?php echo $this->field('contact_person_mail#'.$elementCount)->value(); ?>">

Now I want, to check if the variable is a "http"(a webpage) of an email address and if so, add an "mailto:".

Can you guys help my with that?

You can use:

strpos — Find the position of the first occurrence of a substring in a string.

<a href="<?php echo strpos($this->field('contact_person_mail#'.$elementCount)->value(),"http") !== false ? "" : "mailto:"; 
        echo $this->field('contact_person_mail#'.$elementCount)->value(); ?>
">

Since, you haven't mention the name of that variable I am assuming that contact_person_mail could contain both URL or email.

UPDATE:

In case of ternary operator returns FALSE you don't need to echo anything. since your URL or email is already getting echoed after that. Ternary operator is only of printing mailto:.

So, can I change "$your_variable" to "$this->field('contact_person_mail#'.$elementCount)->value();"? Because that variable can have either a webpage link or email address?

So this would be right? <a href="<?php echo strpos($this->field('contact_person_mail#'.$elementCount)->value(),"http") !== false ? $this->field('contact_person_mail#'.$elementCount)->value(); : "mailto:"; echo $this->field('contact_person_mail#'.$elementCount)->value(); ?> ">

Check the updated code. in case of FALSE you dont need to echo anything. That's what is different in your code and mine.
