PHP - Changing Form Action Field
Hi there,
I was wondering if it was possible to change a forms action field with PHP. Basically, if there are several checkboxes for the user to select and a specific checkbox was selected, how would I redirect users to an alternative webpage on submit? I've been playing around with several methods, and one of them was: Code: [Select] <?php if(isset($_POST['Example']) && $_POST['Example'] == 'FormValueGoesHere') { echo ('./page1.php'); } else { echo ('./page2.php'); } ?> But the form action would only display page1.php even with nothing selected. Maybe I'm just being stupid because it's getting late, but I'd appreciate any assistance. Thanks Similar TutorialsI want to loop through a MySQL table, and perform a calculation based on the current row the loop is on and the previous loop. Say my table has 2 columns - Film_id and FilmRelease, how would I loop through and echo out a calculation of the current FilmRelease and the previous row's column value? Thanks guys I have got to this stage, but for some reason it's not printing out anything Code: [Select] <?php mysql_connect("localhost", "****", "*****") or die(mysql_error()); mysql_select_db("*****") or die(mysql_error()); $sql = mysql_query("SELECT FilmRelease FROM Films_Info") or die(mysql_error()); $last_value = null; while ($row = mysql_fetch_assoc($sql)) { if (!is_null($last_value)) { print date_diff($row['FilmRelease'], $last_value) . "<BR>"; } $last_value = $row['FilmRelease']; } Hi guys, first and foremost I’m not a programmer, but I do have a little problem that I need help with. I have a website and there is a members registration form, within this form there is a Telephone field.
The telephone field requires a certain format e.g. 138 xxxxxxxxx, I would like your help on how to change the format, so that I can input random numbers.
where and how should I be editing this field to achieve the required result?
Thanks in advance.
Hi, I have a script that dumps the information from one of my MySQL tables into a CSV. The script works great, but in the result, the names of the MySQL columns are shown as-is. In other words, I have a column named "field4" that shows up as "field4" in the CSV. How can I modify the columns to more descriptive names without modifying the database itself? Here's my code: Code: [Select] <?php $host = "*********"; $user = "*********"; $pass = "*********"; $db = "database_name"; $table = "table"; $file = "member_information"; $link = mysql_connect($host, $user, $pass) or die("Cannot connect." . mysql_error()); mysql_select_db($db) or die("Cannot connect."); $result = mysql_query("SHOW COLUMNS FROM ".$table.""); $i = 0; if (mysql_num_rows($result) > 0) { while ($row = mysql_fetch_assoc($result)) { $csv_output .= $row['Field'].","; $i++;} } $csv_output .= "\n"; $values = mysql_query("SELECT * FROM ".$table.""); while ($rowr = mysql_fetch_row($values)) { for ($j=0;$j<$i;$j++) { $csv_output .= $rowr[$j].", "; } $csv_output .= "\n"; } $filename = $file."_".date("m.d.y"); header("Content-type: application/vnd.ms-excel"); header("Content-disposition: csv" . date("m.d.y") . ".csv"); header( "Content-disposition: filename=".$filename.".csv"); print $csv_output; exit; ?> The CSV it spits out looks like this: Code: [Select] field1 field2 field3 field 4 info info info info I want it to look like this: Code: [Select] Name Email Location Age info info info info Thanks in advance! When I click the save changes button, I want the user to be brought back to profile.php. Right now they are being brought to editprofile.php. I currently have the form action set to editprofile.php . When the I change it to profile.php my fields won't update. Any thoughts as to where I went wrong? Here is the editprofile.php code. <form action='editprofile.php' method="POST" id="form"> I've heard multiple recommendations when a form needs to post to itself. Some say use PHP_SELF, others say leave it blank (even though it doesn't validate), etc. Please provide the best practice, and reasons why. Thank you
echo("<form method='post' action='{$_SERVER['PHP_SELF']}'>");
echo("<form method='post' action=''>");

Basiaclly what they input into a text field will become part of the URL used in action at the top of the form. So it would look like this: http://www."their input from form".mydomain.com does anyone have any suggestions on how to accomplish this? Thanks How do you have an HTML form process a function for an action? I tried what I have below, but i just can't get it to work right. Any ideas? Thanks for your help. For example: Code: [Select] <?php function UserLookup(){ $searchfield = $_POST['searchfield']; $client = new SoapClient("http://www.domain.com/webservice.asmx?WSDL"); $result = $client->UserLookup(array('searchfield'=>$searchfield)); echo json_encode($result); } if (isset($_GET['submit'])) { UserLookup(); } else { ?> <form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>" > <input name="searchfield" type="text" size="45" /> <input type="submit" value=" Search " /> </form> <?php } ?> 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. It has been brought to my attention that $_SERVER['PHP_SELF']; can be easily hacked. In this code... Code: [Select] <form id="login" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> Do I even need anything in the Action attribute if I am redirecting the form to itself?! Please advise... Debbie My question is, when someone make same html form with action that goes on same php file on my server, so i need to know, can my site be hacked in that way ? I mean if i have form that goes on file /sources/add_user.php and when someone make same html form that goes on www.my-site.com/sources/add_user.php and in that way to add users on my baze ? Hi, I want to make a checkbox that will store the value as the user's database table ID and when the records are checked, I will have a delete, update link to delete/update those records that have their checkbox checked. I know I would need two submit buttons (one for delete and one for update), but the form tag only takes one action attribute, right? So does anyone know what I should do??? Le me know, thanks is there anyway to hide the action URL from html form example: <form name="afrom" action="hide.php" method="post"> so it end up from the user side: <form name="afrom" action="" method="post"> Thanks! Hi, I am newbie to PHP. If any one explain me with a simple example, it would be really great. I have a form page "queue_info.php". After user hits SUBMIT, this page will redirect to an action page "queue_action.php". from form page data are passed using "$quests=$_POST['quests'];" to this action page. Now i need to resend this same data back to the form page "queue_info.php" from action page. How to do this? Appreciate your inputs on this. thanks, prakash I have this form action that checks for errors, if none are found it should go to the confirmation page. Works well in Firefox, however Chrome stays perpetually on the register page. Is there any way to make this work in Chrome as well? Does anyone have any explanation? Thank you very much for your time. Code: [Select] <form action="<?php if(!empty($errors)){ echo "confirmation.php"; } else { echo "register.php"; } ?>" method="POST"> Hi there, I am having some issues with a page failing security tests because of a form. The form's text input files is getting sanitized when posted but the only thing I can think is that the form action="" is $_SERVER['REQUEST_URI'] and this then includes anything that is within the URL. <form name="zipcode" id="zipcode" action="<?php echo htmlentities($_SERVER['REQUEST_URI'], ENT_QUOTES, "UTF-8"); ?>" method="post"> <label for="zip" class="smalllbl">Zipcode: </label> <input type="text" class="smallzip" name="zip" id="zip" value="" /> </form> Has anyone else experienced this when running PCI Compliance style security tests? And if you have, why would this happen as the same form action is used elsewhere with no issues. Many thanks in advance Simon I have a html form that submits to another website. Everything works fine in firefox and chrome however the data is duplicated in IE. Is there some quirk in IE when submitting a form to a different website? This works: Code: [Select] form action="http://localhost/mysite/css/screen.css" method="post"> This does not work: Code: [Select] <?php $link_1 = "http://localhost/mysite/css/screen.css" ; $link_2 = '"' . "http://localhost/mysite/css/screen.css" .'"' ; ?> <form action=<?php echo $link_1;?> method="post"> <form action=<?php echo $link_2;?> method="post"> Why do neither of the PHP variables work? Thanks! Hi I am in the process of converting to Object Oriented from Procedural. To cater for this I have built an admin_login function, contained within a class: 'siteFunctions'. However, I am having trouble pointing the admin form to the function correctly. Every time I click 'submit', the form does not process anything. It doesn't even 'think' about it i.e. show the egg timer.... I have built this script heaps of times using the procedural method, so I guess I am somehow doing something wrong with respect to referencing the action attribute of the form (due to my new approach). I am very new to OO so please go easy on me: I know the script isn't particularly advanced. I just want to get used to putting functions into classes, and then calling the code, before I move onto more advanced stuff. I have placed all of the files within the same folder in order to rule out driectory path issues. Here are the three scripts that I think are relevant (login, functionsClass, and the mysql connection script): Login $pageTitle = "Admin Login"; include("admin_header.php"); include_once("sitefunctions.php"); new siteFunctions(); echo '<div class="admin_main_body">'; <form action="<?php echo htmlentities($_SERVER["PHP_SELF"]);?>" method='post'> <input type="text" name="username" id="username" size="20"> <label>Username</label><br /> <input type="password" name="password" id="password" size="20"> <label>Password</label><br /> <input type="submit" name="submit" id="submit" value="submit"> </form> echo '<div>'; include("includes/admin_footer.php"); sitefunctions.php //$page = "admin_index.php"; class siteFunctions { var $message; function admin_login() { echo '<div class="admin_main_body">'; $message = NULL; if (isset($_POST['submit'])) { require_once ("mysql_connect.php"); if (empty($_POST['username'])) { $u = FALSE; $message .= '<p> Please enter your username </p>'; } else { $u = escape_data($_POST['username']); } if (empty($_POST['password'])) { $p = FALSE; $message .= '<p>You forgot to enter your password </p>'; } else { $p = escape_data($_POST['password']); } if ($u && $p) { // If everything's OK. $query = "SELECT * FROM admin WHERE username= ('$u') AND password=('$p')"; $result = @mysqli_query($GLOBALS["___mysqli_ston"], $query); $row = mysqli_fetch_array($result, MYSQLI_BOTH); if ($row) { session_start(); $_SESSION["admin_id"] = $row[0]; //header("$page"); //Redirects user to admin_index.php //header('location: "$page"'); header ("Location: http://" . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) .
