  • Contact page MVC workflow

    - by alex
    All my previous projects have had this workflow on Contact pages User submits form Controller gets $_POST details Controller validates details (and sets error messages if necessary) Controller sends email Controller redirects to thanks page Is this the standard workflow? I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?

  • Check Avaibility of a page before loading using jquery/ajax

    - by overcomer
    Is it possible check the Accessibility of a page before loading it? I have a form, running on mobile device using wireless connection. The problem is: not always this connection is avaible and i would like to alert the user when is doing a submit or an unload of the page. The problem is that the page contains elements doing redirect like this: <input type="button" value="MyText" onClick="script1;script2;...window.location='mylocation" /> If the user click on this button and the server is not achievable, i will recive some undesiderable errors. Also if I want to generalize my script i do not know the value of "mylocation" previously. The page contains elements to submit the Form also: <input type="submit" name="SUBMIT" value="MyValue" onClick="return eval('validationForm()')" /> For the submitting I'm using the ajaxForm plugin and it works quite well. This is a snippet of code: Thanks to your answer I found the solution to the problem. That's the code: function checkConnection(u,s){ $.ajax({ url:u, cache:false, timeout:3000, error: function(jqXHR, textStatus) { alert("Request failed: " + textStatus ); }, success: function() { eval(s); } }); } $(document).ready(function() { // part of the function that checks buttons with redirect // for any input that contain a redirect on onClick attribute ("window.locarion=") $("input[type=button]").each(function(){ var script = $(this).attr("onClick"); var url = ""; var position = script.indexOf("window.location") ; if (position >= 0) { // case of redirect url = script.substring(position+17, script.lenght); url = url.split("\'")[0]; url = "\'"+url+"\'"; // that's my url script = "\""+script+"\""; // that's the complete script $(this).attr("onClick","checkConnection("+url+","+script+")"); } }); // part of the function that checks the submit buttons (using ajaxForm plugin) var is_error = false; var options = { error: function() { if (alert("Error Message")==true) { } is_error = true; }, target: window.document, replaceTarget: is_error, timeout: 3000 }; $("#myForm").ajaxForm(options); }); I hope that this will be usefull.

  • login not working when changing from mysql to mysqli

    - by user1438647
    I have a code below where it logs a teacher in by matching it's username and password in the database, if correct, then log in, if incorrect, then display a message. <?php session_start(); $username="xxx"; $password="xxx"; $database="mobile_app"; $link = mysqli_connect('localhost',$username,$password); mysqli_select_db($link, $database) or die( "Unable to select database"); foreach (array('teacherusername','teacherpassword') as $varname) { $$varname = (isset($_POST[$varname])) ? $_POST[$varname] : ''; } ?> <form action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post" id="teachLoginForm"> <p>Username</p><p><input type="text" name="teacherusername" /></p> <!-- Enter Teacher Username--> <p>Password</p><p><input type="password" name="teacherpassword" /></p> <!-- Enter Teacher Password--> <p><input id="loginSubmit" type="submit" value="Login" name="submit" /></p> </form> <?php if (isset($_POST['submit'])) { $query = " SELECT * FROM Teacher t WHERE (t.TeacherUsername = '".mysqli_real_escape_string($teacherusername)."') AND (t.TeacherPassword = '".mysqli_real_escape_string($teacherpassword)."') "; $result = mysqli_query($link, $query); $num = mysqli_num_rows($result); $loged = false; while($row = mysqli_fetch_array($result)) { if ($_POST['teacherusername'] == ($row['TeacherUsername']) && $_POST['teacherpassword'] == ($row['TeacherPassword'])) { $loged = true; } $_SESSION['teacherforename'] = $row['TeacherForename']; $_SESSION['teachersurname'] = $row['TeacherSurname']; $_SESSION['teacherusername'] = $row['TeacherUsername']; } if ($loged == true){ header( 'Location: menu.php' ) ; }else{ echo "The Username or Password that you Entered is not Valid. Try Entering it Again."; } mysqli_close($link); } ?> Now the problem is that even if the teacher has entered in the correct username and password, it still doesn't let the teacher log in. When the code above was the old mysql() code, it worked fine as teacher was able to login when username and password match, but when trying to change the code into mysqli then it causes login to not work even though username and password match. What am I doing wrong?

  • PHP Session / Array Problem accesing

    - by Chris
    Hello, I have a form that certain data, which then gets calculated and gets displayed in a table. All the data gets saved in a 2 dimensional array. Every time i go back to the form the new data gets saved in the array. That data will be displayed in the next table row and so on. I have used print_r($_Session) and everything gets properly saved in the array. Although i have no idea how to acces the session variables area, floor, phone, network etc wich are now in the array. Without arrays i stored them in a variable for example $phone , and did calculations with it. But now when i use the arrays, i keep on getting undefined index phone etc... How can i acces these variables, been looking at this for hours without getting any closer to a solution. Any help much appreciated. Regards. First page: if (empty ($ _POST)) ( Mode = $ name $ _POST ['state name']; $ Area = $ _POST ['size']; $ Floor = isset ($ _POST ['floor'])? $ _POST ['Floor'] 0, / / if checkbox checked value 1 else 0 $ Phone = isset ($ _POST ['phone'])? $ _POST ['Phone']: 0; $ Network = isset ($ _POST ['network'])? $ _POST ['Network']: 0; / / Control surface if (is_numeric ($ area)) / / OK ( if (isset ($ _SESSION ['table'])) ( / / Create a new row to the existing session table $ Table = $ _SESSION ['table']; $ Number = count ($ table); $ Table [$ count] [0] = $ file name; $ Table [$ count] [1] = $ size; $ Table [$ count] [2] = $ floor; $ Table [$ count] [3] = $ phone; $ Table [$ count] [4] = $ network; $ _SESSION ['Table'] = $ table; ) else ( / / Create the session table $ Table [0] [0] = $ file name; $ Table [0] [1] = $ size; $ Table [0] [2] = $ floor; $ Table [0] [3] = $ phone; $ Table [0], [4] $ = network; $ _SESSION ['Table'] = $ table; ) header ("Location: ExpoOverzicht.php"); ) else ( echo "<h1> surface Wrong - New try </ h1>"; ) ) When i made the php code withotu the arrays i declared like this, and it worked fine. But now there in the array, and i have no idea how to "acces them" $standnaam = $_SESSION["standnaam"]; $oppervlakte = $_SESSION["oppervlakte"]; $verdieping = $_SESSION["verdieping"]; $telefoon = $_SESSION["telefoon"]; $netwerk = $_SESSION["netwerk"];

  • How to do a Post/Redirect/Get using Sinatra?

    - by John Topley
    What's Sinatra's equivalent of Rails' redirect_to method? I need to follow a Post/Redirect/Get flow for a form submission whilst preserving the instance variables that are passed to my view. Does the redirect method preserve them? (I'm at work at the moment and don't have access to Sinatra to try for myself.)

  • Pass PHP variables without being seen when working with a database generated list

    - by Wilcoholic
    Looking for any help regarding the problem. Here's the deal: I have a database that has a teams table and it contains team_id. On one of my pages, I generate a list of links that contain the team_id of the creator in their get URL. I need the team_id on the next page but can't figure out how to pass it through any other way. Using a form and POST isn't an option because this method would only pass through the last links data on the list. Storing in a session isn't an option either because there is no way to discretely pass the the variables I need to a function to set the session variables. I have tried and it can pretty easily be viewed from viewing the source code. So here's some sample code to see exactly what I'm dealing with. <? if(mysql_num_rows($result2)>0){ ?> <a class="fltrt btn btn-danger btn-small" onclick="test()" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=cancel">Cancel Match</a> <?}else{?> <a class="fltrt btn btn-success btn-small" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=accept">Accept Match</a> <?} ?> The code above is generated multiple times on a page via a while loop that was excluded. I want to pass the match_id and team_id variables without being seen anywhere. If I made this a form, it wouldn't pass the correct variables unless there is only one result at the time (not likely). I'm sure there has to be an easy method that is eluding me, so please share thoughts on how to solve this. I feel as though I am not explaining it well enough, but it's not really easy to explain. I basically want something that works like GET but acts like POST and can be hidden from people viewing source code or link locations. Thanks
