happyhart Posted August 21, 2011 Share Posted August 21, 2011 Can someone please help? I am simply trying to email process a form with checkboxes and then redirect to a thank you page. It works fine as long as at least one checkbox is checked. It breaks if no checkboxes are checked using the implode function to list the "interests". I'm getting this error (and no redirect to my thank you page): Warning: implode() [function.implode]: Invalid arguments passed... <?php if (isset($_REQUEST['submit'])) { $email = $_REQUEST['email']; $firstName = $_REQUEST['firstName']; $lastName = $_REQUEST['lastName']; $address = $_REQUEST['address']; $city = $_REQUEST['city']; $state = $_REQUEST['state']; $zipcode = $_REQUEST['zipcode']; $homePhone = $_REQUEST['homePhone']; $cellPhone = $_REQUEST['cellPhone']; $interest = $_REQUEST['interest']; $imploded_interest = implode(',',$interest); $comments = $_REQUEST['comments']; $to = 'myemailhere@yahoo.com'; $subject = 'Volunteer Signup'; $message = " <html> <head> <title>Volunteer Signup</title> </head> <body> <p>Hello,<br/>A visitor has submitted the following information from the volunteer page:</p> <p><b>$firstName $lastName</b><br/> $address<br/> $city, $state $zipcode<br/><br/> Home Phone: $homePhone<br/> Cell Phone: $cellPhone<br/> Email: <strong>$email</strong><br/><br/> I would like to help in the following ways:<br/> $imploded_interest </p><br/> <p>$firstName would also like share the following comments:<br/> <q><i>$comments</i></q> </p> </body> </html> "; $headers = 'MIME-Version: 1.0' .

voip03 Posted August 22, 2011 Share Posted August 22, 2011 You need to validate the check Box. if(!empty($_REQUEST['interest'])) { $imploded_interest = implode(',',$interest); } Quote Link to comment Share on other sites More sharing options...
happyhart Posted August 22, 2011 Author Share Posted August 22, 2011 @voip, thanks for taking the time to help me. I haven't added validation partially because I don't fully understand how to wrap it all together but mostly because the client wants the form to go through even if nothing is checked. Is there a way to secretly pass a value to the variable "interest" if nothing is checked? That is what I tried to do with the hidden input field. As you can see, I'm very new at this..

voip03 Posted August 22, 2011 Share Posted August 22, 2011 Have you tried 1st code then try this code if(!empty($_REQUEST['interest'])) { $imploded_interest = implode(',',$interest); } else { $imploded_interest =0; } Quote Link to comment Share on other sites More sharing options...
