My db's run on the same server but I also had to add in those other changes to the $link line of code after making the change in my php code in my WP page, and now the form is displaying in my WP page. </p> <p>It has a couple other issues and I'll work on those now, and then I want to connect it to Aweber. At least it's connecting to the db now though - progress is being made! :)</p> <p>JoLynn </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-9467 Sat, 15 May 2010 13:56:24 +0000 yuniar 9467@https://www.machform.com/forums/ <p>That code should be placed into your WordPress post/page, which you can do it from WordPress admin panel. </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-9463 Sat, 15 May 2010 06:46:50 +0000 jolynnbraley 9463@https://www.machform.com/forums/ <p>Hi, in your comment above where you wrote, "also, adjust your php embed code, add the code to re-select your wordpress db. like this:", which is followed by the block of code underneath.....what is the exact name of the file that code is to be placed in? </p> <p>Thanks! </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-6492 Tue, 07 Jul 2009 12:22:41 +0000 bfkouba 6492@https://www.machform.com/forums/ <p>This was helpful... this is the information you need (including that last step) if you're having trouble integrating with wordpress. Worked for me. </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-4670 Sat, 14 Feb 2009 17:19:31 +0000 yuniar 4670@https://www.machform.com/forums/ <p>Ah.. I see. If that is the case, you need to edit another line of db-core.php file.</p> <p>Search for this line:</p> <pre><code>$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die(&#39;Could not connect: &#39; . mysql_error());</code></pre> <p>change the DB_HOST, DB_USER and DB_PASSWORD above with a quoted string, exactly like DB_NAME </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-4658 Sat, 14 Feb 2009 04:50:03 +0000 idckamikaze 4658@https://www.machform.com/forums/ <p>I forgot to mention that the MachForm db and the Wordpress db are on separate servers (I'm on a virtual host). Would I need to define the parameters for the MachForm database in the db-core.php file, or could I import the config.php file into the db-core file? </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-4652 Fri, 13 Feb 2009 18:28:21 +0000 yuniar 4652@https://www.machform.com/forums/ <p>Apparently, WordPress and MachForm are using the same constant name for the database. That's why it won't able to select machform database.</p> <p>To fix it, edit your "includes/db-core.php" file. Around line 12 you will find this:</p> <pre><code>mysql_select_db(DB_NAME) or die(&#39;Could not select database&#39;);</code></pre> <p>change the DB_NAME above with your machform database name, example:</p> <pre><code>mysql_select_db(&#39;my_machform&#39;) or die(&#39;Could not select database&#39;);</code></pre> <p>make sure to put quotes as above.</p> <p>also, adjust your php embed code, add the code to re-select your wordpress db. like this:</p> <pre><code>&lt;?php require(&quot;/appnitro/machform/machform.php&quot;); $mf_param[&#39;form_id&#39;] = 519; $mf_param[&#39;base_path&#39;] = &#39;http://example.com/machform/&#39;; display_machform($mf_param); mysql_select_db(&#39;your_wordpress_db_here&#39;); //&lt;-- this line ?&gt;</code></pre> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-4647 Fri, 13 Feb 2009 04:38:22 +0000 idckamikaze 4647@https://www.machform.com/forums/ <p>That worked and then I got a similar error on helper_functions.php, line 201, function show_message. I changed that to show_machform_message (also used in manage_form, not sure where else), but that only fixed the function conflicts.</p> <p>Now it seems like I'm getting SQL errors. This displays:<br /> <code>select form_name, form_description, form_redirect, form_success_message, form_password, form_unique_ip, form_frame_height, form_has_css, form_active, form_captcha, form_review from ap_forms where form_id=&#39;2&#39; Query failed: Table &#39;db273972956.ap_forms&#39; doesn&#39;t exist</code></p> <p>The only thing I can figure is the query is trying to run on my WP database and not the MachForm database. It isn't critical that I use the PHP embedding feature, but I thought it would be nice to have Wordpress integration. Any thoughts would be appreciated. </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-4632 Thu, 12 Feb 2009 15:28:28 +0000 yuniar 4632@https://www.machform.com/forums/ <p>Go to line 243 of "includes/common-validator.php" file. You'll find this line:</p> <pre><code>function validate_username($value){</code></pre> <p>change it to become:<br /> <pre><code>function validate_user_name($value){</code></pre> <p>or any other similar function name. Thanks for the suggestion on this. </p> https://www.machform.com/forums/topic/problem-with-validate_username-function#post-4616 Wed, 11 Feb 2009 23:28:04 +0000 idckamikaze 4616@https://www.machform.com/forums/ <p>I installed the Exec-PHP plugin for Wordpress to be able to execute PHP on a certain page (where a MachForm would be displayed). When I try to embed the form using the code generated in my admin panel, it gives me an error in the validate_username() function.<br /> <code>Cannot redeclare validate_username() (previously declared in /homepages/32/d239429970/htdocs/mdpc/wp-includes/registration.php:49) in /homepages/32/d239429970/htdocs/machform/includes/common-validator.php on line 242</code></p> <p>I think this relates to my previous post about unique identifiers in XHTML. Wordpress has a registration.php file that uses the validate_username() function. MachForm also uses this function, however, I don't have enough coding knowledge to know how it relates to the ability to embed the form. I used the iframe code and I achieved what I set out to do, but I think this is an important point for future revisions of MachForm. </p>
