You are a life-saver. :)<br /> I will give it a go! </p> https://www.machform.com/forums/topic/blocking-emailadresses-from-email-field-urgent#post-3639 Thu, 13 Nov 2008 20:46:59 +0000 redityo 3639@https://www.machform.com/forums/ <p>Hi,</p> <p>In this case you should add another validation to block those e-mails. Open your "includes/common-validator.php" and add those code on line 28.</p> <pre><code>//validation for email address function validate_blacklist_mail($value){ //define blocked email address $block_email_list = &#39;@test.com,@wow.com&#39;; $blacklisted_mail = explode(&#39;,&#39;,strtolower($block_email_list)); if(in_array(strstr($value[0],&#39;@&#39;),$blacklisted_mail)){ return &#39;This email not allowed&#39;; } else { return true; } }</code></pre> <p>in there I assume you want to block e-mail from test.com and wow.com. After that edit your "includes/post-functions.php" and search on line 289, you'll find this code :</p> <pre><code>$rules[$element_name][&#39;email&#39;] = true;</code></pre> <p>add exactly below that code to activate the validation:</p> <pre><code>$rules[$element_name][&#39;email&#39;] = true; if ($form_id == &#39;11&#39;) { $rules[$element_name][&#39;blacklist_mail&#39;] = true; }</code></pre> <p>Finnaly it also filter the validation only for form 11 :). </p> https://www.machform.com/forums/topic/blocking-emailadresses-from-email-field-urgent#post-3637 Thu, 13 Nov 2008 17:45:24 +0000 MvdL79 3637@https://www.machform.com/forums/ <p>Oh and if it's possible only for specific forms, so we can still use, for example, Hotmail accounts on some forms (e.g. migration forms).</p> <p>Currently we have about 14 active forms. However from form 1 through 11 it's not allowed to use free emailaccounts like Hotmail and Gmail, but on forms 12 through 14 it is allowed to use these.</p> <p>Hopefully I made myself clear! Thank you. </p> https://www.machform.com/forums/topic/blocking-emailadresses-from-email-field-urgent#post-3636 Thu, 13 Nov 2008 17:40:08 +0000 MvdL79 3636@https://www.machform.com/forums/ <p>Yuniar,</p> <p>A "quick" question; is there a fast way to block email accounts like @hotmail.com, @msn.com, @gmail.com, @live.nl, etc. from the email field?</p> <p>Our company does not accept orders from those emailaccounts.</p> <p>Please advice... Thanks in advance! </p>
