    Hi,

    I want to use this method to secure plain mail adresses:
    https://gist.github.com/irazasyed/6621341

    I added the following code to my functions.php:

    function hide_email($email)
    { $character_set = '+-.0123456789@ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz';
      $key = str_shuffle($character_set); $cipher_text = ''; $id = 'e'.rand(1,999999999);
      for ($i=0;$i<strlen($email);$i+=1) $cipher_text.= $key[strpos($character_set,$email[$i])];
      $script = 'var a="'.$key.'";var b=a.split("").sort().join("");var c="'.$cipher_text.'";var d="";';
      $script.= 'for(var e=0;e<c.length;e++)d+=b.charAt(a.indexOf(c.charAt(e)));';
      $script.= 'document.getElementById("'.$id.'").innerHTML="<a href=\\"mailto:"+d+"\\">"+d+"</a>"';
      $script = "eval(\"".str_replace(array("\\",'"'),array("\\\\",'\"'), $script)."\")";   $script = '<script type="text/javascript">/*<![CDATA[*/'.$script.'/*]]>*/</script>';
      return '<span id="'.$id.'">[javascript protected email address]</span>'.$script;
    }


    Usually (e.g. on a normal bootstrap website) I insert my mail adress like this:

    <?php echo hide_email('[email protected]'); ?>

    How can I use this method in Salient and Visual Composer?
    The php code above doesn't work in an unfiltered html field.

    Thanks in advance.

    Hi mdgomes,

    In general its not possible to add PHP code to the pages content areas on wordpress.

    What we can think of now is maybe add that hide_email function to an existing file or something that will place it where you want.

    Alternatively you can use a plugin to add the capability to place PHP code on the page content area and see if it offers a shortcode option so that you can maybe add the shortcode to a text block editor when the editor is in text mode.

    Hope you can work it from there.

    Thanks, I avoided to use own PHP code and use the following Plugin:

    https://de.wordpress.org/plugins/email-address-encoder/

    Works as intended =)
