PHP - How To Encrypt Form Post Data?
How can I encrypt POST data from a form? Basically, I want to ensure that the data on the form is not in plain text ever. Is this possible?
<form method="post"> <input type="text" name="email" size="40"> <input type="password" name="password"/> ... Basically, when this posts, I want to do a foreach on $_POST and see something like: password = 1f3870be274f6c49b3e31a0c6728957f and not password = stringTheUserTyped I hope what I'm asking for is clear. (PHP 5.2.14) Thanks! Similar TutorialsHello everyone... I am developing a software as a service program for use by multiple companies, each would have their own instance of the application... The part that I am not really to clear on, is what would be the most secure, with low latency, PHP method of encrypting/decrypting data to and from the database... all data is sent over SSL... I would also want to use a unique key for each company... Access to the program itself is protected from the outside by a user based log in system... I have a form with lots of fields. How would I run a loop to get each field name and data into an array, so i can then send it off to a function to process each field name / data differently. Instead of typing all the variables in the main function name for each post. Would a foreach statement work? I needed a server side PHP validation script for my form to use on top of client side Javascript as a backup. I found a nice package where I just include the validator and set a few options then it does the rest. However it doesn't seem to work with the action="whateveraction.php" for the form. It will skip all the validation and immediately go to the action script. So I left that blank as you can see in the form below and figured I would send the post data somehow to the script using PHP when the validation is successful. However I am stumped on how to do that can I get some coding help? This is the small validation script. I will attach the formvalidator.php in this post. Code: [Select] <?php require_once "formvalidator.php"; if(isset($_POST['submit'])) { $validator = new FormValidator(); $validator->addValidation("age","req","Please fill in your Age"); $validator->addValidation("mcid","req","Please fill in your Minecraft Username"); $validator->addValidation("description","req","Please fill in a Description"); if($validator->ValidateForm()) { //need something here to have it send the post data to /mcbuildapp/form_submit.php } else { echo "<div class=blockrow><b><font size=5>Form Errors:</font><b></div>"; $error_hash = $validator->GetErrors(); foreach($error_hash as $inpname => $inp_err) { echo "<div class=blockrow><p><font color=red>$inp_err</font></p>\n</div>"; } } } Then the form if it matters.... Code: [Select] <div class="blockrow"> <font size=4><b>Minecraft Building Rights Application</b></font> <br /> <br /> <b>Failing to fill in any of these fields sufficiently will result in an automatic denial of your application!</b><br /> <b>Think of it this way, being lazy and applying wrong is only wasting your time.

[attachment deleted by admin] Ok from one brick wall to the next. After lots of help with my last query I moved onto the next task an I'm completely stuck again. I have a form thats created with a loop. Here is that form <form action="" method="post" id=""> <?php for ($i = 1; $i <= $totalRows_rs_cacheNum; $i++) { echo "<label>Cache ".$i."</label> <span id='sprytextfield".$i."'> <input name='cache[$i]' type='text' value='".$_POST['cache[$i]']."'/> <span class='textfieldRequiredMsg'>Required!</span></span> <div class='clear'></div>"; } ?> <input name="nextbtn" type="submit" value="Next" /> When a user enters data in all the fields, If one piece of information is incorrect an error pops up saying one of the fields you entered does not match the fields in the database. At the same time however i wish to keep the data they have entered in each of the fields. Normally you'd just write value="<?php echo $_POST['fieldName'];?>" but for some reason in this case it does not work. can someone point me in the right direction. I've tried Google many different terms but I can not find the correct term to find my answer. Hence me asking you guys again. Thanks ok..ive done this a million times..i have a working example here and i copied it and amended it for this new project but for some reason i cant get a form to post data to another page. this is the error message i get Notice: Undefined index: username in C:\wamp\www\uni\fyp\site\mobile\login.php on line 16 Notice: Undefined index: password in C:\wamp\www\uni\fyp\site\mobile\login.php on line 17 here is my form code: <form method="post" action="login.php"> <table align="center" cellpadding="0" cellspacing="0"> <tr> <td style="vertical-align:top;">Username: </td><td><input type="text" name="username" value="" /></td> </tr> <tr> <td style="vertical-align:top;">Password: </td><td><input type="password" name="password" value="" /><br /><input type="submit" id="submit" value="Login" /></td> </tr> </table> </form> and here is the code within the login.php where the form should post to $username = $_POST['username']; $password = $_POST['password']; // Help protect against MySQL injection $username = stripslashes($username); $password = stripslashes($password); $username = mysql_real_escape_string($username); $password = mysql_real_escape_string($password); // Selecting data from database where correct username and password are found $sql="SELECT * FROM customer WHERE username='$username' and password='$password'"; $result=mysql_query($sql) or die(mysql_error()); i cant see anything wrong..been looking for hours...please please help me Hi, I'm working on a web application that will interact with an existing website from another company. On the other company's site, there will be a form (using POST) that has my web application as the action element. The user who clicked the submit button will be redirected to my site, where I need to receive the $_POST data from this form to process before redirecting into the web application. I have done work on the other side, using standard form posts to send data to another site, but I've never had to write the code for the receiving end. How do I receive the form data posted from the other website? Can I access the $_POST[''] array as I would with any normal same-site POST transaction? Please let me know if you need additional detail or if my question wasn't clear! I'm fast approaching deadlines and really appreciate your help! Thanks! $post='{"cart_items":[{"configuration":{"price":100,"recharge_number":"9999999999"},"product_id":"999","qty":1}]}';i try this n reslut was :There are no valid items in cart: help me plz Edited by ShivaGupta, 30 November 2014 - 01:11 AM. Hey Guys. I am working with a form that shows the grand total on the checkout page. The value of the grand total is inside a hidden field. When click on submit, the _POST array doesn't get back the last value of the grand total. I need to hit the button twice to get the last value. The weird thing is when I echo the value of the grand total it display the latest value, but not with the POST array
For example. If the grand total is $10.00 and I click on submit. It will show the POST['grand_total'] as empty. If I click on submit again it will show the grand total of $10.00.
Below is my code that I am working with. Any help would be really appreciated.

I want the form data to be 1) stored into a mysql database AND after storing said data, 2) email the same data to our sales department. 1) The form data DOES get stored into mysql database (except for the first two fields, for some weird reason) 2) I added a "mail" section to the php file that stores the data into the database, but it is not working correctly. I have stripped the email portion down to sending just one of the fields in the "message" to make it easier for troubleshooting I have included here, both the form section of the html file, and the formdata.php file that processes the data for your analysis. I am relatively new to php so there are going to be some issues with security, but I can work on those after I get the store & email process to work correctly. Please review my code and see if anyone can be of assistance. I looked through the forums and couldn't find another issue that was the same as mine. If I just overlooked, please tell me the thread post #.

Hi guys, I think I may be losing my marbles over this form I've put together. I'm trying to get my code to post the following to a database but my MySQL and PHP isn't that good, so wondering if any one could possibly suggest what I could do? Here is my code: Code: [Select] <?php // we check if everything is filled in if(empty($_POST['fname']) || empty($_POST['lname']) || empty($_POST['email'])) { die(msg(0,"All the fields are required")); } // is the sex selected? if(!(int)$_POST['sex-select']) { die(msg(0,"You have to select your sex")); } // is the birthday selected? if(!(int)$_POST['day'] || !(int)$_POST['month'] || !(int)$_POST['year']) { die(msg(0,"You have to fill in your birthday")); } // is the email valid? if(!(preg_match("/^[\.A-z0-9_\-\+]+[@][A-z0-9_\-]+([.][A-z0-9_\-]+)+[A-z]{1,4}$/", $_POST['email']))) die(msg(0,"You haven't provided a valid email")); // I think here is where I need to put something to get the data into a table! echo msg(1,"registered.html"); function msg($status,$txt) { return '{"status":'.$status.',"txt":"'.$txt.'"}'; } ?> How do I get the $_POST['day'] and $_POST['month'], $_POST['year'] etc into a table? It should be so easy but my head is hurting from trying lots of things and tutorials online.

I have a nusoap web service running, which is fine, but I need to send a new variable in the parameters which decides what database to use...
This is how I call the function:
$params = array( 'region' => '1' ); $response1 = $client->call('function1', array ($params)); // response will be in JSON So basically I'm using PHP to solve a math problem for me. The user puts in a few parameters and the program runs those numbers through the algorithm and spits out a bunch of xy coordinates. I'm using the PHP SELF method to retrieve the user input. This all works fine, but it's afterwords that I run into problems. I create a drop down menu of all the x values and I want the user to be able to choose any x value they wish and to have the corresponding y value be displayed. The problem is that I have to use another POST command for this and when I do, it wipes out all the computed data. Of course the y-value is never displayed, and there lies the problem. I'm sure there are many ways to get around this, but I could not find one out myself. Anyone have any ideas? Hi guys, I am creating a quiz system for my personal site, I am done with all the quiz questions creating part, but I am stuck with something like... user taking a random sql generated quiz and submitting it.. Here's randomly generated sql quiz, even the answers are in random order: <form method="post"> <b>1. What is color or sky</b> <ol> <li><input name="question_3_answer" type="radio" value="6" /> sky</li> <li><input name="question_3_answer" type="radio" value="8" />blue</li> <-- true <li><input name="question_3_answer" type="radio" value="3" />red</li> </ol> <b>2. What is name of my cat</b> <ol> <li><input name="question_6_answer" type="radio" value="9" />brat</li> <--true <li><input name="question_6_answer" type="radio" value="7" />rat</li> </ol> <b>3. What is name of my pet</b> <ol> <li><input name="question_18_answer" type="radio" value="9" />cat</li> <--true <li><input name="question_18_answer" type="radio" value="7" />dog</li> </ol> </form> Now this is tricky part for me is.. receiving these data in another page.. since it's randomly generated questions, how do I know which question it is? here's example I've tried : $list_all_quiz_questions = $db->get_row("SELECT question_id, its_true_ans_id FROM question_table WHERE quiz_group = 'ef23fsdfers3e' "); $i = 1; foreach ($list_all_quiz_questions as $myquestion) { $answer.$i == $_POST["question_".$myquestion->question_id."_answer"]; //?????????? not working lol ;(( $i++ } I'm doing an ajax call from javascript using jquery library: Code: [Select] ajaxCall: function(process, obj, type){ $.post("registration-post.php", type + "=" + process, function(data){ if(data==""){ $(obj).css(registration.errorNotificationType, registration.validatedColour); }else{ $('.error').append($.trim(data) + "<br />"); $(obj).css(registration.errorNotificationType, registration.errorColour); registration.progress = false; } } ); } When the ajax calls the php page, I want the php page to know what post information the javascript has sent, rather than pre-defining what the PHP should be trying to retrive from the POST data. Something like // pseudo $_POST["whateverwassentfromajax"] I want to do this because I want to have one function doing everything. So in my javascript I am saying, check if the username and email have already been used... But i dont want to call two different php functions. //pseudo function 1(){ $_POST["username"]; } function 2(){ $_POST["email"]; } Is there a special way to know which post data has been sent. Or do i need to do a few if statements in php. II am new to jscript and AJAX and have a problem that I need to solve.
I have a form on which I need to input the RGB values of a color that will be used in the next PHP file.
I have choosen a color chooser written in jscript called JS-Color.
There are a number of pre-written scripts for choosing the color, of which I have used the following:
<script type="text/javascript" src="jscolor/jscolor.js"></script> R<input id="red" size="5"> G<input id="grn" size="5"> B<input id="blu" size="5"> - - - H<input id="hue" size="5"> S<input id="sat" size="5"> V<input id="val" size="5"> <p> Choose any color: <input class="color" id="myColor" onchange=" document.getElementById('red').value = this.color.rgb[0]*100 + '%'; document.getElementById('grn').value = this.color.rgb[1]*100 + '%'; document.getElementById('blu').value = this.color.rgb[2]*100 + '%'; document.getElementById('hue').value = this.color.hsv[0]* 60 + '°'; document.getElementById('sat').value = this.color.hsv[1]*100 + '%'; document.getElementById('val').value = this.color.hsv[2]*100 + '%';">I am trying to work out how to use this to get the 3 values that I can post in a form. Looking at the internet, I have found that AJAX is the easiest way to POST from jscript. I have attempted to write some script, but I'm sure I'm way off the mark.

Is it this.color.rgb[0]*255; for example? I have created a variable $red etc, but it does not even open the test_input.php file. None of the examples I have seen on the internet relate to the task I am trying to figure out. Can anyone advise me? |
