Have not called the function direct yet. Never seen the create_function used before, but it works. </p> https://legacy.forums.gravityhelp.com/topic/pre-populate-understanding-code-example#post-46002 Tue, 10 Jan 2012 17:06:52 +0000 Chris Hajer 46002@https://legacy.forums.gravityhelp.com/ <p>The \ escapes the single quote. Otherwise there would be a syntax error.</p> <p>Not sure on WHY he did it like that, but there are always multiple ways to accomplish the same thing, and this might be one of those cases. Have you tried it by calling the function direct? </p> https://legacy.forums.gravityhelp.com/topic/pre-populate-understanding-code-example#post-45991 Tue, 10 Jan 2012 15:43:27 +0000 sascha 45991@https://legacy.forums.gravityhelp.com/ <p>Hi there,<br /> the original topic (<a href="http://www.gravityhelp.com/forums/topic/right-parameter-names-to-pre-populate-the-names-fields" rel="nofollow">http://www.gravityhelp.com/forums/topic/right-parameter-names-to-pre-populate-the-names-fields</a>) is closed, so I started a new one to ask the question.</p> <p>I am trying to understand some code by David in the following pastie:<br /> <a href="http://pastie.org/1470060" rel="nofollow">http://pastie.org/1470060</a></p> <p>Why does he use the create_function here and not just call the function direct? Is there any reason for this?</p> <p>He uses:<br /> add_filter('gform_field_value_user_firstname', create_function("", '$value = populate_usermeta(\'first_name\'); return $value;' ));</p> <p>I would have used:<br /> add_filter('gform_field_value_user_firstname', 'populate_usermeta('first_name')');</p> <p>What are the \ before the ' for? </p>
