One free alternative is to use this: <a href="http://notepad-plus.sourceforge.net/uk/site.htm" rel="nofollow">http://notepad-plus.sourceforge.net/uk/site.htm</a> "Notepad++ is a free source code editor and Notepad replacement, which supports several programming languages, running under the MS Windows environment." mmason on "Form Validation Rules - More than just forced value or email???" https://www.machform.com/forums/topic/form-validation-rules-more-than-just-forced-value-or-email#post-613 Wed, 23 Jan 2008 10:55:11 +0000 mmason 613@https://www.machform.com/forums/ I would like to add a post validation hook and I see how this is done from reading these posts. However since I am not blessed with line numbers in the php scripts. Could some one please give me another "landmark" to search for besides a line number as posted by Yuniar about 3 months ago: "Modify includes/post-functions.php, insert the code below into line 772, above the query line........"

You can remove that code. Now, what you need to do is to merge the code in hooks/custom_hooks.php You've created two function, simple merge the code from form2_hook_tix_validation() to form2_hook_post_validation(). So the whole function would be something like this: <pre><code>function form2_hook_post_validation($user_input){ $inv = $user_input['element_1']; // Insert office codes here - these are for ONTARIO ONLY if (strcasecmp($inv,"2788") != 0 && strcasecmp($inv,"2816") != 0 && strcasecmp($inv,"2906") != 0 && strcasecmp($inv,"3104") != 0 && strcasecmp($inv,"9999") != 0) { $inv_status = 'Registration is only open to persons with a valid Promotional code'; } else{ $inv_status = true; } if($inv_status !== true){ return $inv_status; } $tix = $user_input['element_7']; if ( strcasecmp($tix,"1") != 0 && strcasecmp($tix,"2") != 0 && strcasecmp($tix,"3") != 0 && strcasecmp($tix,"4") != 0 && strcasecmp($tix,"5") != 0 ){ $tix_status = 'Max five tickets'; }else{ $tix_status = true; } return $tix_status; }</code></pre> <code></code> If you have more fields, do the same as above, just add the code into that function. Let me know if you have any difficulty. mpivon on "Form Validation Rules - More than just forced value or email???" https://www.machform.com/forums/topic/form-validation-rules-more-than-just-forced-value-or-email#post-162 Thu, 25 Oct 2007 07:44:55 +0000 mpivon 162@https://www.machform.com/forums/ Okay. Cool. This worked... sort of. However, I have more than one field on the form that requires error checking. So, following your example, I did the following: Into "Post-Functions.php" I inserted the following code: //post_validation hook <code>if(function_exists("form{$form_id}_hook_post_validation")){</code> <code>$result = call_user_func("form{$form_id}_hook_post_validation",$user_input);</code> <code>if($result !== true){</code> <code>$process_result['custom_error'] = $result;</code> <code>}</code> <code>}</code> <code>//ticket validation hook</code> <code>if(function_exists("form{$form_id}_hook_tix_validation")){</code> <code>$result = call_user_func("form{$form_id}_hook_tix_validation",$user_input);</code> <code>if($result !== true){</code> <code>$process_result['custom_error'] = $result;</code> <code>}</code> <code>}</code> THEN... I added the following code to the Hooks file: <code>function form2_hook_post_validation($user_input){</code> <code></code> <code>$inv = $user_input['element_1'];</code> <code></code> <code>// Insert office codes here - these are for ONTARIO ONLY</code> <code></code> <code>if (</code> <code>strcasecmp($inv,"2788") != 0</code> <code>&& strcasecmp($inv,"2816") != 0</code> <code>&& strcasecmp($inv,"2906") != 0</code> <code>&& strcasecmp($inv,"3104") != 0</code> <code></code> <code>//Promo code</code> <code>&& strcasecmp($inv,"9999") != 0</code> <code>)</code> <code></code> <code>{</code> <code>$status = 'Registration is only open to persons with a valid Promotional code';</code> <code>}</code> <code>else{</code> <code>$status = true;</code> <code>}</code> <code>return $status;</code> <code>}</code> <code>function form2_hook_tix_validation($user_input){</code> <code>$tix = $user_input['element_7'];</code> <code>if (</code> <code>strcasecmp($tix,"1") != 0</code> <code>&& strcasecmp($tix,"2") != 0</code> <code>&& strcasecmp($tix,"3") != 0</code> <code>&& strcasecmp($tix,"4") != 0</code> <code>&& strcasecmp($tix,"5") != 0</code> <code>)</code> <code>{</code> <code>$status = 'Max five tickets';</code> <code></code> <code>}</code> <code>else{</code> <code>$status = true;</code> <code>}</code> <code>return $status;</code> <code>}</code> <code></code> So... I can't figure this out?

Please try again or contact XXXX'; }else{ $status = true; } return $status; }</code></pre> <code></code> This is our custom validation code. In this case my form_id is 99 and my element name is element_1. Simply adjust these to match your form id and element name. If those sounds too difficult, send me an email and I'll help you figuring out. mpivon on "Form Validation Rules - More than just forced value or email???" https://www.machform.com/forums/topic/form-validation-rules-more-than-just-forced-value-or-email#post-123 Fri, 19 Oct 2007 04:47:35 +0000 mpivon 123@https://www.machform.com/forums/ Hello, I am interested in creating a form with validation logic that checks to see if a user is from a pre-defined (or authorized) list. i.e.: The code would look something like this: if ( strcasecmp($inv,"1111") != 0 && strcasecmp($inv,"2222") != 0 && strcasecmp($inv,"3333") != 0 && strcasecmp($inv,"4444") != 0 && strcasecmp($inv,"5555") != 0 ) { die("Registration is only open to recipients with an authorized promo code. Please try again or contact XXXX. "); } How would THIS be implemented?
