PHP - Form Being Double Submitted
I've got a BIG problem...
When a user submits my form it works fine, displays a "Transaction Success/Failed", and e-mails me a confirmation. However, if the user then navigates to another page (e.g. "Home"), and then clicks their browser's "Back" button, my form gets re-submitted?! This is on a VPS, but I just chatted with server support and they are saying, Quote register_globals = Off So what is going wrong?! Debbie Similar TutorialsI now know how to append GET over normal hyperlinks, but I don't know how to do it with form submissions. Here's the problem: I have a form like this one: <form method="GET" action=""> <?php require_once ('sort_category_func.php'); $switch = 1; sort_category ($switch); ?> + Most Liked <input type='checkbox' value='mostLiked' name='mostLiked' /> <br /> <input type="submit" name="sortSubmit" value='Go' /> <br /><br /> </form> And the variables: // DROP DOWN MENU VARIABLES $select_category = $_REQUEST['sort_category']; $most_liked = $_GET['mostLiked']; I'm using a while loop to list user submission, you can also sort them by category which works over GET, this works as long as there is no GET data already in the URL, but as soon as there is GET data it won't work anymore. Here's an example: If I have a user profile page opened like this: profile.php?user=konopkov And a category has been chosen to sort the user's submissions the URL will change to: profile.php?sort_category=Logos INSTEAD it should be: profile.php?user=konopkov&sort_category=Logos As I said I know how to achieve this with hyperlinks now, but I have no clue how do it with form submissions. Any suggestions? Thanks. Up until now, I have been writing Forms that submit back to themselves. Now I want to break up my code. I usually have this PHP at the top of my forms... Code: [Select] <?php // ******************************************** // HANDLE FORM. * // ******************************************** if ($_SERVER['REQUEST_METHOD']=='POST'){ // Form was Submitted (Post). If I change my Form Action to point to another script, will this code work in that new script?? (In other words, will Script_B be able to detect $_SERVER['REQUEST_METHOD']=='POST' ??) Thanks, Debbie I have an account on theirsite.com and I want to be able to submit my login credentials from mysite.com/page1.php and then redirect back to mysite.com/page2.php. I've been Googling for hours now and nothing I can find works and I don't know a thing about cURL and would rather not get into it. Not to mention, I'm using free hosting for now and I don't believe I'm able to use cURL anyways. I can get it to log in with the credentials just fine, that's no problem, but I just have no clue how to get it to redirect back to my page or just send the credentials and then staying on my page because I could work with that as well (send credentials to theirsite.com from mysite.com/page1.php and staying on mysite.com/page1.php). Is there anyone that could give me a hand on how to do this without using cURL since my php.ini is not editable? Thanks Hi
We have a nicely working smtp contact form, however the form redirects to the contact.php file as default I presume, when we want it to go to a thank you page. Can you [please take a look at the code below and clarify where I need to put the thank you page URL;
$redirect_url = "http://".$_SERVER['SERVER_NAME']; //Redirect URL after submit the form $mail->From = $mail->Username; //Default From email same as smtp user $mail->FromName = "Mobile website"; $mail->AddAddress("essexcarrentals@yahoo.co.uk", "Mobile Website"); //Email address where you wish to receive/collect those emails. $mail->WordWrap = 50; // set word wrap to 50 characters $mail->IsHTML(true); // set email format to HTML $mail->Subject = $_POST['Enquiry']; $message = "Name: ".$_POST['name']." \r\n <br>Email Address: ".$_POST['email']." \r\n <br> Phone: ".$_POST['phone']." \r\n <br> Vehicle: ".$_POST['select']." \r\n <br> Dates: ".$_POST['dates']; $mail->Body = $message; if(!$mail->Send()) { echo "Message could not be sent. <p>"; echo "Mailer Error: " . $mail->ErrorInfo; exit; } echo "Message has been sent"; header("Location: $redirect_url"); } ?> I have tried replacing the http:// but this returns a page underfined error on submission? We appreciate your help on this one guys :0) Ash --- Hi: I am using this code for my contact us feedback form: Code: [Select] <?php $error = NULL; $myDate = NULL; $FullName = NULL; $Address = NULL; $City = NULL; $State = NULL; $Zip = NULL; $Phone = NULL; $Email = NULL; $Website = NULL; $Comments = NULL; if(isset($_POST['submit'])) { $myDate = $_POST['myDate']; $FullName = $_POST['FullName']; $Address = $_POST['Address']; $City = $_POST['City']; $State = $_POST['State']; $Zip = $_POST['Zip']; $Phone = $_POST['Phone']; $Email = $_POST['Email']; $Website = $_POST['Website']; $Comments = $_POST['Comments']; if(empty($FullName)) { $error .= '-- Enter your Full Name. <br />'; } if(empty($Email)) { $error .= '-- Enter your Email. <br />'; } if($error == NULL) { $sql = sprintf("INSERT INTO myContactData(myDate,FullName,Address,City,State,Zip,Phone,Email,Website,Comments) VALUES ('%s','%s','%s','%s','%s','%s','%s','%s','%s','%s')", mysql_real_escape_string($myDate), mysql_real_escape_string($FullName), mysql_real_escape_string($Address), mysql_real_escape_string($City), mysql_real_escape_string($State), mysql_real_escape_string($Zip), mysql_real_escape_string($Phone), mysql_real_escape_string($Email), mysql_real_escape_string($Website), mysql_real_escape_string($Comments)); if(mysql_query($sql)) { $error .= 'Thank you for contacting us.'; mail( "d@direct.com", "Contact Request", "Date Sent: $myDate\n Full Name: $FullName\n Address: $Address\n City: $City\n State: $State\n Zip: $Zip\n Phone: $Phone\n Email: $Email\n Website: $Website\n Comments: $Comments\n", "From: $Email" ); } else { $error .= 'There was an error in our Database, please Try again!'; } } } echo '<span class="textError">' . $error .

I haven't been able to figure it out with JavaScript/PHP, so I posted my original code in hopes that someone will have an idea. Anyone? Thanks! Hello everyone, I'm having a difficult time figuring out what my problem is here. I'm trying to submit a couple of strings (to the user they are messages to be sent to other users) and I am having trouble with the string being cut off at quotation marks. Here is the code that I'm using: Code: [Select] <?php if (isset($_POST['submit'])) { $staffmessage = $_POST['staffmessage']; $studentmessage = $_POST['studentmessage']; echo "$staffmessage<br /> <br />$studentmessage"; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> </head> <body> <?php $message1="This is a test message. It does not get cut off here when the \"quotation marks\" are added."; $message2="This is a test message. It DOES get cut off here when the \"quotation marks\" are added."; ?> <form name="form" method="post" action="test.php"> <textarea class="textarea" name="staffmessage" rows="12"> <?php echo $message1; ?> </textarea></p> <input name="studentmessage" type="hidden" value="<?php echo $message2; ?>" /> <input class="submit2" type="submit" name="submit" value="Send Message" /> </form> </body> </html> The result that I'm getting is that when $staffmessage is echoed, I get the full message. When $studentmessage is echoed, the message gets cut off at the first quotation mark. The only thing that is different when creating these two variables is that $staffmessage is submitted using a "textarea" field in the form, and $studentmessage is submitted using a "hidden" field in the form. Other than that, they are handled the exact same way. Can anyone please help me figure out how to remedy this so that $studentmessage is not cut off at the quotation mark? Thanks in advance for your help! Hello all, I am having a bit of trouble with this contact form. Everything submits fine, errors work and all but the information isn't sent to my inbox.

Can someone please show me how to send in array in between pages for future ? Good afternoon,
I was wondering if you could help me out with a few things. I have created a registration page and it stores the information into my database. A success page then appears with some of the details they entered as a confirmation page. Unfortunately I cannot get the information to appear on the page. I have included some code, any help would be greatly appreciated.
<?php Hi, I am working on a registration login system and after a person registers and logs in, they will get the option to upload a profile picture. The picture and registration info will need to be in two different tables. I want to know the best way to associate the two (registration info and photo) so that I know who's picture goes with what registration info? I thought about IP address, but a user might register on one computer and login and upload a photo on another computer. If I have a standard HTML form in my PHP script and the User submits the form - which resubmits to itself for processing - and then the User hits the "Back" button and then the "Forward" button, why does the Form and its data get re-submitted?! What mechanics are exactly happening? I had a "Submit Payment" page that was doing that and so people would get charged twice and that is obviously a big problem. Please help me understand what causes that issue and different ways to fix it. Thanks, Debbie Hi all I have a field in mySQL table called dimensions. It has the double quote in in for inches - " When I echo the result from the mySQL query on the item page (Customer facing) it's fine. However, I have built a form so that the administrator can edit the dimensions in the admin panel and when I echo it out in to the form field it stops when it gets to the double quotes? Pete So I built a form and if anyone puts // in the text area field named Code: [Select] name="background" it won't work... it fails. This prevents users from entering website URLs, which is an issue since the form is related to website design. I think I have everything else working just fine. Any ideas how I can change this so it will work and allow // ? There may be other things that cannot be entered or maybe a security risk I am missing... here is the code... Code: [Select] <?php // version 2.2 // All placeholders that are used such as {yourEmail@yourDomain.com}, {yourSolve360Token}, {ownership}, // {categoryId}, {templateId} should be replaced with real values without the {} brackets. // REQUIRED Edit with the email address you login to Solve360 with define('USER', 'me@me.com'); // REQUIRED Edit with token, Workspace > My Account > API Reference > API Token define('TOKEN', 'itentionallydeleted'); // Get request data $requestData = array(); parse_str($_SERVER['QUERY_STRING'], $requestData); // Configure service gateway object require 'Solve360Service.php'; $solve360Service = new Solve360Service(USER, TOKEN); // // Preparing the contact data // $contactFields = array( // field name in Solve360 => field name as specified in html form 'firstname' => 'firstname', 'lastname' => 'lastname', 'businessemail' => 'businessemail', 'cellularphone' => 'cellularphone', 'background' => 'background', ); // kill form if spammers use the siteURL field if ( $_GET['url'] != '' || $_GET['firstname'] == 'Your Name' || $_GET['businessemail'] == 'Email Address' ) {header("Location: http://www.openpotion.com/new/error");} else { $contactData = array( // OPTION Apply category tag(s) and set the owner for the contact to a group // You will find a list of IDs for your tags, groups and users in Workspace > My Account > API Reference // To enable this option, uncomment the following: // Specify a different ownership i.e. share the item 'ownership' => 18634876, // Add categories 'categories' => array( 'add' => array('category' => array(18660073)) ), ); // adding not empty fields foreach ($contactFields as $solve360FieldName => $requestFieldName) { if ($requestData[$requestFieldName]) { $contactData[$solve360FieldName] = $requestData[$requestFieldName]; } } // // Saving the contact // // Check if the contact already exists by searching for a matching email address. // If a match is found update the existing contact, otherwise create a new one. // $contacts = $solve360Service->searchContacts(array( 'filtermode' => 'byemail', 'filtervalue' => $contactData['businessemail'], )); if ((integer) $contacts->count > 0) { $contactId = (integer) current($contacts->children())->id; $contactName = (string) current($contacts->children())->name; $contact = $solve360Service->editContact($contactId, $contactData); } else { $contact = $solve360Service->addContact($contactData); $contactName = (string) $contact->item->name; $contactId = (integer) $contact->item->id; } if (isset($contact->errors)) { // Mail yourself if errors occur mail( USER, 'Error while adding contact to Solve360', 'Error: ' . $contact->errors->asXml() ); die ('System error'); } else { // Mail yourself the result mail( USER, 'A new sales lead has been posted to Solve360', 'Contact "' . $contactName .

Jason [attachment deleted by admin] Hi there, I have a newsletter sign up form which just puts the data (id and email) into a mysql table. To stop people hacking the site, is there a way to make sure the only thing being submitted in the input is an email address? Here's my current form and submit php: Code: [Select] <?php $mailer = $_GET['mailer']; if ($mailer == 'added') { $email=$_POST['email']; if($email == '') { echo '<div class="daily_not_submitted"><span style="padding-right:6px;"><img src="https://store.huhmagazine.co.uk/images/cross.jpg"></span>Please fill in all the fields.</div>'; }else { $sql="INSERT INTO `dailymailer` (`email`) VALUES ('$email');"; $result=mysql_query($sql) or die(mysql_error()); if($result){ echo "<div class='daily_submitted'><span style='padding-right:6px;'><img src='http://www.huhmagazine.co.uk/images/uploaded/checkboxtick.jpg'></span>Thank you.</div>"; } else { echo "Error\n"; } } } ?> <div id="sidebarnewsletter"> <form name="mailinglist" method="post" action="?mailer=added"> <input type="text" name="email" class="sidebarnewsletter" placeholder="Enter Your Email Address" /> <input type="submit" class="sidebarnewsletter_button" value="Sign Up"> </form> <div class="clear"></div> </div> I'd like to edit specific parts of a submitted text what is the best way to do this? For example I get the following text: [name country] is very cold this time of year. Because I like the cold I would love to live there [end of line 2] whole lot more text here until [name country] if this text here exists, blabla [but Germany] is blabla [end of line] in some cases some more text here [summary] bla bla The text in the brackets are words that I already know before it has been submitted. Getting the words out has been part of my previous script, using preg_match and put them in variables. I want to put the first portion of the text in a row, if 2nd, 3rd and 4th portion exist, put them in a row too. Any ideas? [edited] I prefer to have these portions cut out and put in a variable. So I end up having a few variables and can later echo that out in rows Edited by dde, 18 January 2015 - 04:01 AM. I am trying to filter characters that get submitted into forms and than database. I have been paying with trim function $string = $_POST[name]; $newstring = trim($string,"W"); echo "$newstring"; but it does not seem to do what I really need. If I enter name World I do get "orld" back, but what if I want to filter out W (or w) and L (or l) to get "ord". I am mainly going after removing ' " ; : . > , < - _ ( ) * & ^ % $ # @ ! \ | / ? I know there is a different way to do it, but it has been long tome since I have seen it, and I do not know where. Thanks for your help Hello, Basically, What I'm looking for would be for a method of blocking certain email addresses from being submitted in a form, I need it to block certain emails that are on the list. I think the best way to describe it would be a form submission blacklist that is checked before it gets submitted. Many thanks |
