I've reduced the code to simplify it.

It has to be something with the implementation. </p> https://legacy.forums.gravityhelp.com/topic/sharing-a-global-variable-between-forms#post-40900 Sat, 12 Nov 2011 11:28:16 +0000 JimBurke 40900@https://legacy.forums.gravityhelp.com/ <p>Anybody there ? </p> https://legacy.forums.gravityhelp.com/topic/sharing-a-global-variable-between-forms#post-40491 Tue, 08 Nov 2011 14:50:13 +0000 JimBurke 40491@https://legacy.forums.gravityhelp.com/ <p>I want to declare a global - $TournamentID to share between forms on the site. The user can select the TournamentID from a dropdown on Form1 and that is set for the rest of the site until it is changed.<br /> In the pre_render of each other form I want to use this global to know what data to pull back from the database (MySQL).</p> <p>I declare $TournamentID in functions.php and have get and set functions for manipulating the global, to save having to declare the global wherever I need it.<br /> In Form1, the pre_render can set/get the global value no problem.<br /> However when I go into the pre_render of Form2, this global is null !</p> <p>How/where do I declare this global ?</p> <p>I know I can pass parameters in the request and that works fine, but a global would save lots of code and make life so much easier.</p> <p>I must be doing something fundamentally wrong because I cannot find anything closely related in here or on the web.</p> <p>I'm using PHP on WordPress, both up-to-date. The platform is Windows Server 2003 with IIS.</p> <p>Any ideas ?</p> <p>Jim </p>
