PHP - How To Resend Data From Action To Form Page?
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 Similar TutorialsWhen I submitted my Form & refresh then browser resend all data again into database, So anybody know any solution of this to avoid data resend after refreshing browser.. 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=''>");
making it not say resend after sending something + refreshing the page
In the same $-POST , i wanted to perform update and delete. With the updated and deleted database, I need to select the updated data from the database. However, it tells me: Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in... .I am new to sql in php, is it true that i cannot perform sql in this way? Or is there any suggestion to perform select straight after deleting and updating?
CANCEL BOOK RESERVATION

{
$query = "DELETE FROM reserved_books WHERE id='$resid';"; //delete reservation

Hi, I am sending data from a form to a URL using $_GET but I would also like the user to be redirected to a thankyou page which is a different URL. Does anyone know if this is possible? Thanks, I ve been having trouble processing form data to the same page as the do on facebook comments. Can php scripts do that. Help me guys!! Hello, Curious to know if someone could point me in the right direction, been struggling with this for a bit now. I have a HTML page with a search field, I can enter a search term and hit the submit button and I am directed to my search.php page with the appropriate results. What I am looking to accomplish is having the search results from the search.php page displayed in a text area below my search field in my HTML page. I have included an image to better describe what I am looking to accomplish: Additionally below is the source from my HTML page and search.php page: page.html <form name="search" action='search.php' method="post"> <input type="text" class="myinputstyle" name="search" value="search" onClick="this.value=''"/><br> <input type="submit" value="submit" class="myinputstyle"> </form> search.php <?php $search = "%" . $_POST["search"] . "%"; mysql_connect ("localhost", "game_over", "Ge7Ooc9uPiedee3oos9xoh4th"); mysql_select_db ("game_over"); $query = "SELECT * FROM game_over WHERE first_name LIKE '$search'"; $result = mysql_query ($query); if ($result) { while ($row = mysql_fetch_array ($result)) { echo "Name: {$row['name']} " . "{$row['lname']} <br>" . "Email: {$row['email]} <br>" . } } ?> Any insight would be most appreciated. Thank you. 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"> how do I put a get id into this form, or use $myvar?: Code: [Select] <form action='read2.php?id=' method="post" name='myForm' id="myForm"></form> Im having some problems with my PHP program... Im trying to get the imformation send to my inbox, but when i push the submit button; i get no email and the "thank you message" is incomplete.. (see attachement: thankUmessage.png) I have to say, im not really a PHPfreak , I understand this language a little..

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 Hi guys, I want to create a piece of script that takes my users to a website based of there input in a form. 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 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 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 } ?> 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'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. 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 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 |
