phpauthor Posted May 29, 2011 Share Posted May 29, 2011 I'm just learning about PHP and I'm diving in head first by attempting to modify our web site's contact form. I'm wishing to stop the form from erasing previously entered values upon "failed" data validation. It's of course going to be annoying to our visitors if their hardworked entries disappear just because they left out a name or entered an illegal email address. I regret that some potential solutions found on this forum and other locations on Google didn't seem to help on my page. As you can see, the validation is done with PHP's version of if-elseif-else. Later I'll be adding a reCAPTCHA and I hope that whatever I learn here might be useful for the potentially same problem when I am adding the CAPTCHA. The actual contact form is at http://www.woofwoofwoof.org/contact/index.php. Thank you in advance for your taking the time to help me what originally appeared to be a simple problem. I have read the rules and I hope I've followed the rules -- please let me know if I committed any sins of omission or commission. Now, for your Sunday reading pleasure, here's the code: CODE STARTS HERE ==================================== <?php include("../common/docType.php"); ?> <?php include("../common/htmlOpen.php"); ?> <head> <title><?php include("../common/titleBar.php"); ?> - Contact us!</title> <meta name="description" content="Call or email us with questions or orders."> <meta name="keywords" content="Barking Dog Chocolatiers, Charlotte NC, chocolate, contact us, telephone, email, e-mail"> <meta name="geo.placename" content="Charlotte, North Carolina"> <meta name="geo.region" content="US-NC"> <meta name="author" content="Joal Fischer"> <meta name="verify-v1" content="1aqZs7xrrfI3lp1RaWDkHHjY9UQZIbq2z/mIVdFeXiI=" /> <?php include("../common/headInclude.php"); ?> <script src="../common/common.js" type="text/javascript"></script> <link rel="Stylesheet" href="../css/contact.css" /> </head> <?php // Success/Fail message $msg = ""; $brisket = ""; // Target Email $targetEmail = "barkingdog@bellsouth.net"; // Process Submissions if(isset($_POST['submitted'])) { if($_POST['submitted']) { // process form. $guestName = $_POST['guestName']; $cityState = $_POST['cityState']; $emailAddress = $_POST['emailAddress']; $phone = $_POST['phone']; $msgSubject = "Barking Dog Chocolatiers Inquiry"; $msgContent = "FROM: $guestName\n"; $msgContent .= "City/State: $cityState\n"; $msgContent .= "Phone & time to call: $phone\n"; $msgContent .= "\nInquiry:\n"; $msgContent .= stripslashes($_POST['msgContent']); // Trial if then else reversed from Dan's original allowing maybe multiple tests in sequence -- in action if($guestName == "") { $keepvar = "1"; $msg = "<p style='color: red; font-weight: bold; font-size: 14px; margin: 12px 0px 0px 0px;'>Please enter a name!</p>"; } elseif($emailAddress == "") { $msg = "<p style='color: red; font-weight: bold; font-size: 14px; margin: 12px 0px 0px 0px;'>Please enter a valid email address!</p>"; } else { mail($targetEmail, $msgSubject, $msgContent, "From: $guestName <$emailAddress>\nX-Mailer:PHP/" . phpversion()); $msg = "<p style='color: darkgreen; font-weight: bold; font-size: 14px; margin: 12px 0px 0px 0px;'>Thank you!

Hybride Posted May 29, 2011 Share Posted May 29, 2011 Please use the code tags next time. For all of your input, you need to use the actual input name when echoing the value to retain the input value. So, your <input tabindex="1" class="itemContent" type="text" name="guestName" value='<?php echo $_POST['Name']; ?>' /> becomes <input tabindex="1" class="itemContent" type="text" name="guestName" value='<?php echo $_POST['guestName']; ?>' /> Or, your <input tabindex="2" class="itemContent" type="text" name="cityState" /> becomes <input tabindex="2" class="itemContent" type="text" name="cityState" value='<?php echo $_POST['cityState']; ?>' /> Quote Link to comment https://forums.phpfreaks.com/topic/237796-contact-form-values-disappear-upon-failed-validation/#findComment-1221959 Share on other sites More sharing options...
phpauthor Posted May 30, 2011 Author Share Posted May 30, 2011 Dear brthl, Not only are your suggestions working perfectly, but also the clarity of your writing is really good. I hope one of your jobs is writing textbooks or instructions! Everything worked when I used your ideas -- I even figured out how to make it work for the textarea. However, when I go to test the 5th content area (your question), I can't find a string name to represent what exists in the "your question" textarea. If I can get a name for the string itself so I can test for a length (say, <5), then I can require a question prior to "Submit" being successful. Here's the new code; the part in reference is marked in red as "// OH HELP!" on the left margin. Thank you again for your articular and ridiculously prompt response.

mikesta707 Posted May 30, 2011 Share Posted May 30, 2011 please use code tags. and instead of using strlen($msgContent) why dont you try using strlen($_POST['msgContent']) the reason being you set $msgContent to a value that will almost always have a length larger than 5 in case you dont know, you can use code tags like so [code] php and html code here [/code] OR [code=php:0] just php code here [/code] Quote Link to comment https://forums.phpfreaks.com/topic/237796-contact-form-values-disappear-upon-failed-validation/#findComment-1222089 Share on other sites More sharing options...
phpauthor Posted May 30, 2011 Author Share Posted May 30, 2011 Thanks to both of you -- both of you wrote to the point and in a manner that was easily comprehended even though that section of PHP is new. It works perfectly and will help us get more coherent requests from customers as well as reduce spam. I really appreciate your time. -- Joal P.S. Please keep fingers & toes crossed as I gingerly approach adding a reCAPTCHA.
