Search around line 349 for this block of code:</p> <pre><code>if(empty($result)){ return sprintf($error_message,&#39;%s&#39;,$value[0]); }else{ return true; }</code></pre> <p>replace it with this one:</p> <pre><code>if(empty($result)){ return sprintf($error_message,&#39;%s&#39;,$value[0]); }else{ //block Yahoo if(strpos(strtolower($value[0]), &#39;yahoo&#39;) !== false ){ return &quot;Sorry.

An example: First, have the form user enter their email address and then use form logic to direct to them to the actual form page where you are collecting whatever information you are looking for and if they submit a yahoo address, use logic to direct the user to a page that "nicely" (if you are looking to be nice) tells the yahoo.com users that you can not accept emails from yahoo.com.</p> <p>Well, guess that won't work. Sorry about that zn92, the continue button gets in the way.</p> <p>-David </p> https://www.machform.com/forums/topic/blocking-yahoo-accounts-in-email-field#post-21184 Sun, 08 Jun 2014 02:24:08 +0000 zn92 21184@https://www.machform.com/forums/ <p>Is there a way to modify the email field so that yahoo addresses are not accepted? </p> <p>Thanks! </p>
