PHP - Help With An Action Tag!
Hi
I am building a class to manage site users (Via a CMS). In order to complete this I am building a delete/remove user function/method. Things are going ok (I think), but I am confused about what to put in the action tag of the form being used to process the data. Before coding my method, I referred to a script that someone showed me which does something similar in functionality: it deletes photos previously uploaded to a folder, and also removes the associated information from the database. I used this script as the framework for the code that I am working with. Eveything seems to be working fine - EXCEPT - when I click on the 'delete users' button, nothing happens. The first thing that I examined for error was the action attribute within my form. The value of the action attribute is: action = "<? php htmlentities($_SERVER["PHP_SELF"]) ?>" This format has worked for previous forms. I compared this to the action attribute within the script that I was using as a guide. It's value is set as follows: action = "remove_photo.php?<?php echo "action='godel' ";?> In this instance, remove_photo.php is the file that is being used to both process and display the form. The reference script works perfectly but it uses a procedural approach . For my application, I am using a more object oriented approach, so both my opening and closing form tag elements are stored in a seperate file to the class file that processes it. I am new to OO but relatively comfortable with the paradigm so far (my other methods etc are working fine). I therefore suspect that the reason for my script's inability to process is due to the action attribute setting (I cannot be 100% sure of course!). I am going to therefore apply the action attribute settings used successfully in the reference script, to the application that I am building. However, the trouble is, I don't understand it I don't like it when something works, but I can't see the logic behind why it does. I am not concerned about the form id or method attrbutes. I understand what is going on there - and why they are set as they are. However, the action attribute is very difficult to understand for the following reasons: 1/ There is no variable/method/entity/object/ANYTHING called 'godel' elsewhere in the reference script. For this reason I thought that it might not be needed, so removed the bit of code within PHP tags concerning it: <?php echo "action='godel' ";?> - When I did this - the script didn't work. In fact - nothing at all would process. This was a similar result to what was happening with the script I am building. 2/ I then put the PHP line back in, but replaced 'godel' with 'something'. I saved and processed the form. - it worked. 3/ I then tried it again replacing 'godel' with an empty string i.e: ' '. - it worked. Has anyone come across forms being processed in a similar way before? If so, please could you explain what is happening here. I can't find anything relating to this type of occurence online.... I am going to place the php tags in the file I am building, to see if it has the desired effect. If it does, I will obviously keep it. But not understanding what is happening, or why it is happening is very annoying!! Thanks Similar TutorialsI have an action that will take a long time to finish, so how can I run this action in background? So I will not have to wait it ends... When I click the save changes button, I want the user to be brought back to profile.php. Right now they are being brought to editprofile.php. I currently have the form action set to editprofile.php . When the I change it to profile.php my fields won't update. Any thoughts as to where I went wrong? Here is the editprofile.php code. <form action='editprofile.php' method="POST" id="form"> im making this tool to clean up some data from a sql database, i made a php code to list what i need, thats player name,lvl and id from table_A, the problem is i want to delete from table_A and from table_B all the results from php code , they have in common the id and as a condition the lvl must be lower then 10, it seems i cant make it delete from table_B also,please help me!! a button of the end of the page to delete all that includes same id from both tables is what im looking for! Code: [Select] <table<?php echo $tableSet; ?>> <tr> <td width="*" align="center">Rank</td> <td width="*" align="center"><font color="#000000">Name</td> <td width="*" align="center"><font color="#000000">money</td> <td width="*" align="center"><font color="#000000">id</td> <td width="*" align="center"><font color="#000000">lvl</td> </tr> <?php $rank = mysql_query('SELECT name,money,id,level FROM table_A WHERE level < 10 ' .' ORDER by level desc LIMIT '.$limit.';'); $i=1; while ($row = mysql_fetch_array($rank)) { echo '<tr><td align="center">'.$i.'.</td> <td align="center"><font color="#0000FF">'.$row['name'].'</td> <td align="center"><font color="#0000FF">'.$row['money'].'</td> <td align="center"><font color="#0000FF">'.$row['id'].'</td> <td align="center"><font color="#FF0000">'.$row['level'].'</td> </tr> '; $i++; } ?>this is showing which player names goes to id(from table_A) i need to delete from table_a where the ids shown are lower then lvl 10(the ones result from code above) and same ids from table_b (the rank is just to show me ho is highest lvl) echo(" <form method = \"get\" action = \"DeleteApp.php?pname=\" . $Applications['Name'] . \"> <input value='Delete' type='submit' /> </form> "); Why is this redirecting to: DeleteApp.php?. Instead of what you can obviously see what it's supposed to redirect to. Hi everyone I am trying to pass a php variable ($R1 = 1) in to action script flash 8. After this variable is in flash 8 I want the action script to do a if statement that says if the php variable is = 1 then display layer or object. However i am not sure how to do this any help would be great thanks Freid001 PS if this is not possible to do with php and action script please say thanks I know that PHP is server-side, but I wondered whether anyone had a similar issue that they got around... here's my problem... I've made a psycho-analysis tool for Facebook where it runs your Facebook friends through a database of words to get their psychological preferences (that all works)... I then have a link so that users can tell their friends about the service (it's free, so I want to get it to spread virally) but I'm having a few issues with the link... At the moment, it all works from a Facebook point of view, but when they click on the link, it takes them to an almost-blank page with a bit of code on it. I know what this code is and why it's there, but I'd like to hide it behind a branded page, ideally with Ajax. When I tried to use Ajax for it, it wouldn't accept the URL that was sent. The link has to have a URL sent to Facebook like this: Code: [Select] https://graph.facebook.com/feed?access_token=149324721793321|HarGd6ioqoroENE9gv2758rfeYY&message=I%27ve+just+psycho-analysed+my+Facebook+friends+using+Manteya%27s+Facebook+Friend+Checker+%28http%3A%2F%2Fwww.manteya.com%2Ffacebook-friend-checker%29+so+that+I+can+communicate+better+with+you.&id=100001925276042 but for obvious reasons, you can't post it as an Ajax variable by using the: Code: [Select] http://www.url.com/test.php?id=$variable; Is there a way I can get around the problem? I guess the issue is that Facebook needs the detail in the URL, but PHP won't let me send it like this. I have thought about uploading the URL to a database and shortening the URL, then posting that, which would then re-direct, but that's a messy way around I'm sure you smart people have done something like this before. To see my existing (almost) working example, visit http://www.manteya.com/ffc Thanks, Neil Hello everyone from a php newbie, I have a option selections box and need to select an action depending on the results. Its for an insert script for items into a Database and depending on the chosen option it add the picture to the DB table The selection options are <select name="extension" style="font-size:18px"><option value="pdf">PDF</option><option value="zip">ZIP</option><option value="powerpoint">PowerPoint</option></select> the Swtich is switch $_POST['extention']{ case 'zip': echo $insert_image = $_POST['extension'].'winzip.gif'; break; case 'powerpoint': echo $insert_image = $_POST['extension'].'ppt.gif'; break; default: echo $insert_image = $_POST['extension'].'products/pdf.gif'; } Would someone please tell me if this is correct syntax? Or have i got it horribly wrong! Thank you for your a help Charlie Hi,
I'm using an example below regarding a whole URL. I'm looking for some conditional PHP that will display certain content depending on if the URL contains the word 'liz' if not, display else.

Hi all, I my making a site which to be easier i have made a querystring statement, but the issue is that when accessing /?action= shows index and ?action=register shows register great!, when accessing root / of the site or index.php and displays Undefined index: action , when clearly i have defined action with $id, so why is php saying it is not. I know there is the option for error_reporting(0), but i want to know why this is happening. Edit: the script is, and runs fine other than the error! Code: [Select] <?php $id = "action"; $string = $_GET["$id"]; if ($string == "register") { echo 'register'; } else { echo 'index'; } ?> Many Thanks hi i am carl i am quite new to php and i am haveing a problem with my code this is the error Code: [Select] Notice: Undefined index: action in sale.php line 30I was on the understanding if it could not find " ?action" it would go to default witch it does but it thoughs up the error sorry for my spellings thanks in advance carl Code: [Select] <style type="text/css"> <!-- body,td,th { color: #FF0000; } body { background-color: #CCFFFF; } a:link { color: #FF0000; } a:visited { color: #FF0000; } --> </style> <script type="text/javascript" language="JavaScript1.2" SRC="scripts/stm31.js"></script> <?php session_start(); include 'mainmenu.php'; print "<table width=100% height='400' border='0'> <tr> <td width='700' valign=top >"; #if(isset($_GET["action"])) switch($_GET['action']) { case 'sale': sale(); break; case 'wanted': wanted(); break; case 'free': free(); break; case 'add' : add(); break; default: home(); break; } function home() { print "<center><h3>for sale,wanted or free items</h3><br /> here you can view <br /> <a href='sale.php?action=sale'>Items For Sale</a><br /> <a href='sale.php?action=wanted'>Items Wanted</a><br /> <a href='sale.php?action=free'>Free items</a><br /> <a href='sale.php?action=add'>Post items</a><br /> "; } function sale() { print "<center><table BORDER=4 CELLPADDING=2 CELLSPACING=2 WIDTH=95% valign=top> <tr style='background:gray'> <th>Item name</th> <th>Description</th> </tr></center><br />"; include "config.php"; $result= mysql_query("SELECT * FROM sale ")or die(mysql_error()); while($r = mysql_fetch_array($result)) { print "<tr> <td><center>{$r['iname']}</center></td> <td>{$r['dec']}</td> </tr>"; } print "</table>"; } function wanted() { print "<center><table BORDER=4 CELLPADDING=2 CELLSPACING=2 WIDTH=95% valign=top> <tr style='background:gray'> <th>Item Wanted</th> <th>Description</th> </tr></center><br />"; include "config.php"; $result= mysql_query("SELECT * FROM wanted ")or die(mysql_error()); while($r = mysql_fetch_array($result)) { print "<tr> <td><center>{$r['iname']}</center></td> <td>{$r['dec']}</td> </tr>"; } print "</table>"; } function free() { print "<center><table BORDER=4 CELLPADDING=2 CELLSPACING=2 WIDTH=95% valign=top> <tr style='background:gray'> <th>Free Item </th> <th>Description</th> </tr></center><br />"; include "config.php"; $result= mysql_query("SELECT * FROM free ")or die(mysql_error()); while($r = mysql_fetch_array($result)) { print "<tr> <td><center>{$r['iname']}</center></td> <td><center>{$r['dec']}</center></td> </tr>"; } print "</table>"; } function add() { print " <center><table BORDER=4 CELLPADDING=2 CELLSPACING=2 WIDTH=95% valign=top> <tr style='background:gray'> <th>Item posting</th> </tr></center><br />"; include "config.php"; print "<th>Your Name: <br /> <form method='post' action='pros.php'> <input type='text' name='name' size='35' /> <br /> Your Email:<br /> <input type='text' name='email' size='35' /> <br /> <select name='type' size='1'> <option value='sale'>For Sale</option> <option value='wanted'>Wanted</option> <option value='free'>Items for free</option> </select> <br /><br /> Item Name: <br /> <textarea name='iname' rows='2' cols='15'></textarea><br /> Message: <br /> <textarea name='dec' rows='4' cols='40'></textarea> <br /> <img src='captcha.php'><br /> Enter the code above: <input type='text' name='captcha'> <input type='submit' value='post' /></th>"; } print "</table>"; print " </tr> </table></td> </tr> </table>"; ?> It has been brought to my attention that $_SERVER['PHP_SELF']; can be easily hacked.

Please advise... Debbie Completely new to PHP here, so on my website I'd like a specific image to appear according to whether or not the user in my DB has a row called 'premium', with a value of 1. I've tried figuring it out on my own but I'm stuck. I watched a video of someone doing something similar so this is what I have currently, but I'm aware it's totally incorrect. //init.php file
<?php
if (session_status() == PHP_SESSION_NONE) {//php >5.4
session_start();
}
$_SESSION['user_id'] = 1;
$db = new PDO('mysql:host=127.0.0.1;dbname=loginsystem', 'root', '');
$userQuery = $db->prepare("
SELECT idUsers, uidUsers, emailUsers, pwdUsers, premium
FROM users
WHERE idUsers =:user_id
");
$userQuery->execute(['user_id' => $_SESSION['user_id']]);
$user = $userQuery->fetchObject();
//webpage in which the image will appear
<?php
require_once '../includes/init.php';
?>
<?php if($user-> premium): ?>
<img src="../../img/premium.png" alt="Swiftify+"></a>
<?php else: ?>
<img src="../../img/swiftify.png" alt="Swiftify+"></a>
<?php endif; ?>
My question is, when someone make same html form with action that goes on same php file on my server, so i need to know, can my site be hacked in that way ? I mean if i have form that goes on file /sources/add_user.php and when someone make same html form that goes on www.my-site.com/sources/add_user.php and in that way to add users on my baze ? I'm making a simple shopping cart. I have a strange issue when I add a product to the cart - the correct id registers ("1"), but the size registers as "0" when it should be "sizel". Can anyone see why is this happening? <?php if (isset ($_GET['action']) && $_GET ['action'] == add || size) { $id = intval($_GET['id']); $_SESSION['cart'][] = $id; $size = intval($_GET['size']); $_SESSION['cart'][] = $size; } $cart = $_SESSION['cart']; if (!$cart) { echo "No product in cart."; } elseif ($cart) { foreach ($_SESSION['cart'] as $id) { echo $id; } foreach ($_SESSION['cart'] as $size) { echo $size; } } ?> Code: [Select] <A href="index.html?action=add&id=1&size=sizel">Add to cart</A> Hi, I'm creating a PHP application to handle my SQL server and I've run into a bit of a problem; I have two files atm: mainClass.php and testSite.php My mainClass.php looks like this: Code: [Select] class mainClass { private $host = 'localhost'; public function createDb($user,$pass,$dbName) { $con = mysql_connect($host, $user, $pass); if (!$con){ die('Could not connect: '.mysql_error()); } $sql = "CREATE DATABASE `$dbName`;"; if (!mysql_query($sql)){ die('Error 1: '.mysql_error()); } mysql_close(); } }and testSite.php looks like this: Code: [Select] <!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8"> </head> <body> <h1>testSite for my PHP app</h1> <?php function __autoload($className){ require_once "./classes/{$className}.php"; } $test = new mainClass(); ?> <form name='createDb' method='post' action=''> User: <input type='text' name='user'><br> Password: <input type='password' name='pass'><br> dbName: <input type='text' name='dbName'><br> <input type='submit' value='Create DB'> </form> </body> </html> What I'm asking is if it is possible to make the form-action from testSite.php run the createDb function from mainClass.php I have pretty much no idea how to do it but I tried like this: Code: [Select] <form name='createDb' method='post' action="<?php $test->createDb($_POST['user'],$_POST['pass'],$_POST['dbName']); ?>"> User: <input type='text' name='user'><br> Password: <input type='password' name='pass'><br> dbName: <input type='text' name='dbName'><br> <input type='submit' value='Log in'> </form>But that just made the whole form disappear so now I'm completely lost, any help greatly appreciated. PS: I'm doing this to get better at PHP so please don't come with advice like "use a framework" or "there already are applications that handles this", I know there is. So I have an application that allows users to earn points after logging in and visiting their account page using the following: Code: [Select] $addviews = mysql_query("UPDATE users SET viewlimit = viewlimit + 100 WHERE user_id = '".$_SESSION['userId'] . "' "); This works fine except that by simply refreshing the page the user will gain another 100 points, and on and on.... What would be a simple way to only award the points once a day? |
