PHP - Adding Session Entity From A Html Form Input
I am a little experienced with PHP sessions, but not totally as I haven't got my head completely around its logic yet, as your about to see.
I wonder wondering how I can go about adding a session entity from a HTML form input? I'm guessing it will be something like: $_POST['name'] => $_SESSION['delivery']['name']; Then, to echo the session entity, you would simply do something like: echo $_SESSION['delivery']['name']; ? Similar TutorialsSo, I have two forms.. One for displaying a submitted name. And one for displaying an array of submitted words. At the very top of my index.php, I have: Code: [Select] <?php session_start(); And only in my Second form, for displaying array of words, I've put a 'clear' button to clear the array, which works : Code: [Select] elseif (isset($_POST['reset'])) { $_SESSION['words'] = ''; unset($_SESSION['words']); session_destroy(); } Problem: When I've submitted a name in the First form, and then submit a word in the Second form, the name of the First form disappears! This is also happening the other way, as well as using the reset button for the Second form. Should I use Two Sessions? Is this possible? And how do I do it? Thanks. Hi all I have a php form as follows: <form action="basket.php?action=add&id=1&qty=1" method="post" name="buy-product"> <input name="initial_1" id="initial_1" type="text" size="8" maxlength="1" /> <input name="initial_2" id="initial_2" type="text" size="8" maxlength="1" /> <input name="initial_3" id="initial_3" type="text" size="8" maxlength="1" /> <input name="send" type="submit" class="contact-form-button" id="send" value="Submit" /> Basically I need to add the three initials into a session so that they can be shown in the shopping cart next to the product. How do I add the initials to the session and how do I output them to the shopping cart? At the start of my basket.php script I have: $cart = $_SESSION['cart']; $action = $_GET['action']; $id = $_GET['id']; $qty = $_GET['qty']; $initial_1 = $_POST['initial_1']; $initial_2 = $_POST['initial_2']; $initial_3 = $_POST['initial_3']; I now need to create a table with the cart showing item, price and initials. Cheers Pete. Hiya pplz. I am trying to add: class="keyboardInput" to activate a javascript script to an input box. This is the line im trying to add it to: <td><?php echo form_input(array('name'=>'quantity','value'=>$item['quantity'],'size'=>'2'));?></td> I have tried: <td><?php echo form_input(array('name'=>'quantity','value'=>$item['quantity'],'size'=>'2'));? class="keyboardInput"></td> didn't work. Any help would be great. Ian The PHP code sends me an email from the server, but the user input is empty or "blank". I only receive: "From: \ Email: \ Subject: \ Message: " and that's it. How do I fix my PHP and/or HTML code to receive user input from the form? Attached is my existing HTML and PHP code that doesn't send me any "user input" from the form. Thanks to anyone who can help!!
Hi all I am trying to write a piece of code that takes the value from a form and checks it via an SQL table then adds the session value and the value from the SQL table into the rest of the code as a string. It is for a voucher code in a shopping basket: if(isset($_POST['voucher_code'])) { $vouchercode = $_POST['voucher_code']; $sqlvoucher_code = mysql_query(" SELECT * FROM `voucher_codes` WHERE name = ".$vouchercode.""); $getvoucher_code = mysql_fetch_array($sqlvoucher_code); $_SESSION['voucher_code'] = $_POST['voucher_code']; $voucher_code = $getvoucher_code['value']; header("Location: basket.php"); exit; } Every time I add a value into the form that I know is in the DB it returns a value of 0 even though the value in the DB is 15.95. Please help! Thanks Pete How can i keep adding value to a session??? I need to somehow keep storing more values into an array. session_start(); // store session data $_SESSION['tune_name']=$_GET['tune_name']; $_SESSION['tune']=$_GET['tune']; print_r($_SESSION); So this is what i get from the print_r(); Array ( [attach] => Array ( ) [backups-2] => true [dnb] => true [house] => true [tech-house] => true [uk-garage] => true [uk-grime] => true [uk-hip-hop] => true [uncategorized] => true [warehouse] => true [views] => Music/dnb/Gold Dust (Vocal VIP Mix)_DJ Fresh_192.mp3 [tune_name] => Music/dnb/Dj Ss - We Came To Entertain (Sub Zero Remix).mp3 [tune] => Array ( ) ) ok what i need to do is everytime i click it saves that value above but just appends another value to the array so the session can keep getting larger and larger??? Any help please. I have created a session array on one page and stored some values as $_SESSION['users'] = array( "id" => $row['id'], "fname" => $row['ufname'], "lname" => $row['ulname'] ); and then on another page I have some more values for the same session array "boss" => $row['bossid'], "tasks" => $row['tasks'], "timeframe" => $row['tframe'] I want to add these values into session array both keys and values. is there any way of doing this?

Thanks. I am trying to create a website that after you receive an email you have to use the email address and password to confirm account. Then the next page allows you to change your password. I want to save the users email from the first page and use it in the SQL statement in the second page to locate the user in the DB and update the data.

I have the same code in a development server running fine, but in my prod server it is failing. Here is the main issue: I have a user authentication routine that accepts UserID and Password from a form and validates it against a MySQL database. So to start, UserId and Password are entered via POST variables as is standard: $UserId=@$_POST['UserId']; $Password=@$_POST['Password']; The Password is encrypted using a standard crypt method such as: $encrypt = crypt($Password,'6!68$7435!'); And this is stored in a MySQL database. This part is working fine, that is, the password is encrypted in value and stored in the MySQL database as 'epasswd'. On login, I am using session, so a standard session_start() and eventual session_destroy() on logout are used. The reason I mention this is because I suspect my issue is session related. So normally this works well. User logs in and I check credentials as follows in one part of my auth routine: elseif(UserAuth($UserId,$Password)){ $UserLogin=$UserId; session_start(); $_SESSION['UserLogin'] = $UserLogin; sql_insertActivity(); header("Location: home.php"); And the auth routine is as follows: <? function UserAuth($UserId,$Password){ global $conn; $Stmt="select epasswd from Users where UserId='$UserId' and Approved='1' or Approved='-1' or Approved='-2'"; $Result = mysql_query($Stmt, $conn) or die(mysql_error()); $Result=mysql_fetch_row($Result); $epasswd=$Result[0]; $retval=($epasswd==crypt($Password,$epasswd)); return($retval); } ?> So I am checking for a valid UserID and Password on form input, and I have a few other variables set for approved status. The retval checks the password they enter versus the encrypted value for a match. This usually works well. Then login occurs and session started, etc. Here is the issue. I added a quick admin routine a little while ago which helps reset a user's password to a temporary value. Once this value is set, along with a setting of approved=-1 in my database, then the user is re-directed to a Change Password screen to update his or her password. *Note: I changed the value to 'Charlie' for this discussion purpose. Here is that quick admin routine I run when I need to change a User to a temp setting: // ----- Establish database connection ----- require "../inc_php/inc_mysql_prod.php"; // $UserId=@$_GET['UserId']; $Password='Charlie'; $encrypt = crypt($Password,'6!68$7435!'); $sql = "UPDATE Users set epasswd='$encrypt', approved='-1' where UserId='$UserId'"; mysql_query($sql, $conn) or die(mysql_error()); So this does work as I validate the UserID is updated in the MySQL database along with an encrypted value for 'Charlie'. However, this is where things breakdown going forward. When the user logs in with the temp credentials, and enters in the Change password routine, their new password is saved in the table. However, when logging back in with the new credentials, the new password is not valid. And what's odd is that 'Charlie', the temp password, works for them on login and nothing else, no matter how many times they change the password in the form. So seems a case of session management out of control? What is the issue? I am defining session on all Php pages used, and have a logout to destroy session, etc. The temp password routine is something I run as an admin in the system and it doesn't have a session start statement. And I am not defining any global vars for Password. I lloked into session management and tried some UNSET paths and such, but may not be doing this correctly. Also I did a complete stop apache, remove all php sess_ files, restart and to no avail. I tried the clear my client side cookies deal in the browser, and still the same problem. What is odd is that this same set of code works fine on my other server, but breaks down on the mirrored server. They are essentially twins in all setup. Some minor differences between the two servers regarding PHP setup that might(?) make a difference.

This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=330084.0 I have a website with a variable number of inputs in various categories. I want to allow the user to add rows to the table with the input lines in every category. The table looks like this:

});
I get the wow alert on page load and whee when I click the link:
<tr id="add_field"><th><a href="#">Click to add another line</a></th></tr>that I added to the bottom of the table before the </table> but I do not get an additional line I have tried moving the add_field line outside of the table and changing the <tr></tr> to a <p></p> but that does not help. Hello people. Thank you to everyone who has helped me in the past, this is a great forum full of very helpful members. I am trying to put a pilots logbook application together for the members at microlightforum.com and here is the form that I have put together. What I would like to know is how to code the first "Auto Insert" button so that it takes the time from the variables $takeoff_hr and $takeoff_min and $landing_hr, $landing_min I would like the time difference from taking off to landing putting in the "ws_captain_hrs" box and the "ws_captain_min" box. Therefore if someone took off at 12.30 and landed at 13.50 the "ws_captain_hrs" box should read "1" and the "ws_captain_min" box should read "20" The idea behind this is that it makes it easier for the user to only have to insert take off time and landing time, then click the appropriate button to put the data into the box.

My problem is when i use multiple of those input boxes and submit the form the $_FILES variable only reads 1 of those boxes.. This is the javascript im using: Code: [Select] function addImageBox() { var imageBoxes = document.getElementById("imageBoxes"); var tr = document.createElement("tr"); var td = document.createElement("td"); var td2 = document.createElement("td"); var inputFile = document.createElement("input"); inputFile.setAttribute("type", "file"); inputFile.setAttribute("name", "image[]"); inputFile.setAttribute("style", "width: 450px"); td.appendChild(document.createTextNode("Image")); td2.appendChild(inputFile); tr.appendChild(td); tr.appendChild(td2); imageBoxes.appendChild(tr); } When i add 2 boxes (making it 3 boxes on the page in total) and count the $_FILES var after submiting the form, the count method returns 1, and when i var_dump it only 1 array is in $_FILES. Any idea's? thanks! I am using API-Platform, Doctrine, and Symfony with entities that utilize class type inheritance to extend an abstract entity. I've been running into one issue after another primarily related to the serialization process (serialization groups, parent annotations not propagated to the child, etc), and while I am sure user error on my part is part of the culprit, it appears that API-Platform and potentially Symfony and Doctrine don't fully support entity inheritance. My reason for thinking so is the incredibly sparse amount of documentation on the subject and remarks on quite a few github issues posts and other blogs how it is "bad practice". For instance, say I have Mouse, Cat, and Dog which all extend AbstractAnimal, and each has a bunch of common properties such as birthday, weight, etc, and methods such as eats(), sleeps(), etc. Sorry in advance for using hypothetical entities but I don't think doing so distracts. I like how inheritance allows me to keep all common properties in a single table, but can let that go. More importantly, the subset mouse, cat, and dog table shares an ID from the animal table allowing me to associate all animals to some other table (i.e. many-to-one to person whether they are their pet or many-to-many to country whether they are native to a country), and to retrieve a list of animals and filter by some property or type as needed without a bunch of unions. To me, this sounds like inheritance, but if the products I am using don't support it very well, it doesn't matter. First question. Is entity inheritance considered bad practice? And even if not, is it common for frameworks to limit their level of support for them? If so, what can I do about it? Maybe favor composition over inheritance? Okay, great, I now have a single animal table which makes all my SQL concerns issues go away and I am pretty confident that my serialization issues will also go away. All I need to do is inject each animal with some "thing" to make them a mouse, cat, or dog. But what do I call this thing? I've struggled with this topic for a while and asked the same question regarding how to deal with BarCharts, PieCharts, GaugeCharts, LineCharts, etc all being charts but all acting slightly differently, and never really came to any conclusion. For a non-hypothetical scenario, I have BacnetGateway and ModbusGateway which extend AbstractGateway. Okay, this one is easy and I change to just having a Gateway and inject either BacnetProtocol or ModbusProtocol. For another non-hypothetical scenario, I have PhysicalPoint which represents some real environmental parameter, VirtualPoint which represents combining one or more PhysicalPoints or VirtualPoints, and TransformedPoint (feel free to provide a better name) which represents performing some time function such as integrating over a given time. Currently, they all extend AbstractPoint, but if I was trying to do so with composition, I could inject PointType but don't think doing so makes sense. For my hypothetical scenario, do I make a DNA interface and inject an Animal with DogDNA to get a dog? I really need to get my head around this once and for all. Thanks I can create a one-to-one relationship between two tables by placing a unique constraint on the foreign key and making it NOT NULL, and make it one-to-at-most-one by removing the NOT NULL constraint. My question is what criteria should one use to determine which table holds the foreign key? For instance, I have the Car and Motor entities as shown below where one Car has one Motor, and conversely one Motor is used by one Car.
AbstractPart
Car extends AbstractPart What reasoning should one use to determine whether the Car table contain the Motor ID or should the Motor table contain the Car ID? Is there a way to make it
How can I go about removing a $_SESSION entity if certain array values of it equal a specific value? I am thinking something along the lines of this: if (isset($_SESSION['cart']['content'][$_POST['id']])) = array ('sizes' => 0, 'sizem' => 0, 'sizel' => 0, 'sizexl' => 0) { // remove $_SESSION['cart']['content'][$_POST['id']] } Hello I am working on my graduation project and I have a critical problem with my php code and I am just beginner in php coding. I am reading from text file IDs of papers and want to link between the ID that I read form my text file and the XML file so that is my code : <?php $file = fopen("abstract/Temp_id.txt","r"); $ids; while(!feof($file)) { $ids = fgets($file); $xml = simplexml_load_file("abstract/$ids");//abstract is the folder which I save my files and //read from it $title="bibliomisc =".$xml->articleinfo[0]->bibliomisc; echo $title; echo"<a href=abstract/$ids title='Click to open '>$ids</a>"; } fclose($file); ?> BUT I worked on openssl and it is working if I give it the name of ID e.g. $xml = simplexml_load_file("abstract/8104317");//it is working but if I read from file I got that error Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "8104317.xml " in /opt/lampp/htdocs/GP/xml_test.php on line 9 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 bibliomisc = 8104317.xml Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "" in /opt/lampp/htdocs/GP/xml_test.php on line 9 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 Notice: Trying to get property of non-object in /opt/lampp/htdocs/GP/xml_test.php on line 12 bibliomisc = help please thanks |
