Hi!

The problem is caused by the quotes, you need to escape them correctly, try:

$pm_ui = '<button id="pmBtn" onclick="postPm(\''.$u.'\',\''.$log_username.'\',\'pmsubject\',\'pmtext\')">Send</button>';

In your case you're including PHP variables and your using single quotes, so you have to escape those to create the javascript arguments, and make the variables print their values. Here are few valid possible combinations:

$z = 'red';

$a = '<b class=\''.$z.'\'>Hi</b>';
$b = '<b class="'.$z.'">Hi</b>';
$c = "<b class='$z'>Hi</b>";
$d = "<b class=\"$z\">Hi</b>";

Check the docs for more information: https://php.net/language.types.string
