I'm trying to create a contact form on my own. I noticed that it can be achieved by placing the form inside an article, instead of a custom html module.
In the client side, it seems to work. I even added a captcha manually (the re-captcha plugin doesn't seem to work for me). The problem is, I set form's action property as "mail.php", and just added this "mail.php" file to the the template root. The "mail.php" supossedly retrieves the data send by post, and finally composes and sends the email, showing a "message send" notification.
Anyway, when I click on submit, the form page is just reloaded. I guess that Joomla! can't find my "mail.php". I guess that this issue is related to the joomla structure and my inability to place the "mail.php". Any help will be wellcome.
This is how my article looks like (wysiwyg editor mode disabled):
<form action="mail.php" method="post" target="_blank">
<p><label for="nombre">Nombre:</label></p>
<p><input maxlength="50" name="nombre" size="30" type="text" /></p>
<p><label for="email">Email:</label></p>
<p><input maxlength="50" name="email" required="required" size="30" type="text" /></p>
<p><label for="asunto">Asunto:</label></p>
<p><input maxlength="150" name="asunto" size="30" type="text" /></p>
<p><label for="mensaje">Mensaje:</label></p>
<p><textarea cols="50" maxlength="700" name="mensaje" required="required" rows="8"></textarea></p>
<div class="g-recaptcha" data-sitekey="6Lefblahblahblahblah"> </div>
<p><input type="submit" /></p>
</form>
