PHP - How To Login To A Page, Scrape A Value And Then Submit A Post Form.
Alright, so I play a browser game called Politics and War. I run an alliance that has 74 members. In that alliance we offer a bank service for all our members, but I - being the leader - am the only one who can access the bank. I have been building a site that works with the game API to gather data for members and create a dashboard. One of the features I am trying to build is allowing them to withdraw from their account instantly.
So, what I need: To be able to submit a POST request to login to the site (specifically on this page --> https://politicsandwar.com/login) with my username and password, but then I need to keep the session active and navigate to a different page (the alliance bank page). On that page I first need to scrape a value from a hidden input (token) and then I need to submit a POST request to this same page while still being logged in.
I am not asking someone to do it for me, but rather someone to help me know how to go about this. I have never submitted post requests with PHP, but I have used PHP cURL in the past. I also have made POST requests with JS, but never PHP.
Thank you so much for anyone that is able to help! Similar TutorialsFor my site I need to screenscrape a page on a site. The problem is, to access the page that contains the data I need, I have to login to my account first. I know there are ways to simulate a form submission with ASP, but my server is Linux and can't use ASP. I'm wondering if any of you know how I would be able to simulate a POST with something like cURL? And possibly write an example script? Thanks in advance. (This may be in the wrong section, please move it if it is. Thanks) Hi everyone, I am making a screen scraper in php which scrapes the usernames from forum posts and stores them in an SQL database.

Hi all, I'm trying to scrape the contents of a page that is behind a login screen; namely: http://my.mail.ru/apps. Here's my code. It almost works, but doesn't appear to be properly logging in -- I just get a login screen on the url download. Any ideas? Thanks much. Here's my code <?php $ch=login(); $html=downloadUrl('http://my.mail.ru/apps', $ch); echo $html; function downloadUrl($Url, $ch){ curl_setopt($ch, CURLOPT_URL, $Url); curl_setopt($ch, CURLOPT_POST, 0); curl_setopt($ch, CURLOPT_REFERER, "http://my.mail.ru/cgi-bin/login?noclear=1&page=http%3a%2f%2fmy.mail.ru%2fapps%2f"); curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0"); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); $output = curl_exec($ch); return $output; } function login(){ $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://my.mail.ru/cgi-bin/login?noclear=1&page=http%3a%2f%2fmy.mail.ru%2fapps%2f'); //login URL curl_setopt ($ch, CURLOPT_POST, 1); $postData=' page=http%3A%2F%2Fmy.mail.ru%2Fapps%2F &Login=username &Domain=mail.ru &Password=password'; curl_setopt ($ch, CURLOPT_POSTFIELDS, $postData); curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt'); curl_setopt ($ch, CURLOPT_FOLLOWLOCATION,1); curl_setopt ($ch, CURLOPT_MAXREDIRS, 10); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); $store = curl_exec ($ch); return $ch; } ?> Hello. I hope one of the PHP/HTML gurus here can help me. I have a web page that has been altered a bit to add some Google Analytics stuff and I've moved it to a 2nd directory. The original one works fine, the 2nd one won't post the form when I click the submit button. 1st URL https://www.theneutralizer.info/neutralizer 2nd URL: https://www.theneutralizer.info/neutralizer2 I have changed the action property to the correct script, and it does exist. But the problem is when clicking the button nothing happens. Anyone have any ideas? I can send the PHP code if needed, but since it's HTML output, it should work the way it is displayed in the browser.

When you press submit on the index.php, it takes you to thanks.php. then, after 5s, it takes you back to index.php. My question is: How could I make it so when I press submit, the box submits the form, but instead of redirecting to thanks.php, it displays the same thank you message on the side, but stays on index.php? If that didn't make sense, let me know.

Any idea about this problem will be appreciated. Thanks Hi All, Is there any way that PHP can detect if a page has been refreshed? Basically I have a form that when submitted, inserts a row in to a database, but I am finding that when I refresh the page, it repeats the insert statement. Any ideas? Thanks Matt I am creating a user inbox system. I am retrieving all the unread messages. Each message row contains a "reply" form. So say I have 10 messages showing on a single page. That's 10 forms. What I would like to know is how can I submit any one of the 10 forms and not have it affect the remaining 9 forms? Here is the basic code.
if(isset($_POST['submit'])) {
$post_message = trim($_POST['message']);
$errors = array();
$db->beginTransaction();
if(empty($post_message)) {
$errors[] = 'The message field can not be empty!';
}
if(empty($errors)) {
$db->commit();
echo 'success';
} else {
$db->rollBack();
}
}
<form action="" method="post">
<fieldset>
<textarea name="message" maxlength="10000" placeholder="What would you like to say?"></textarea>
</fieldset>
<fieldset>
<input type="submit" name="submit" value="Submit" />
</fieldset>
</form>
Hi everyone, as the title stated, I would like to know how I could submit a form in one page(cart) and unset a session variable on other page.
Right now my form is setting a variable within the page back to 0, however I would like the form to unset the session variable from other page as well.
The issue with my code is that every time I attempt to clear out all items, my code can empty out the cart. But whenever I close and reopen the cart, the same content will show up again. So I need to unset the session variable.
Please let me know what should I do in order to solve the problem and I greatly appreciate your help.
My code is currently looking like this:
cart.php
if(!empty($_GET['aID']))
{
$aID = $_GET['aID'];
echo $aID;
if(isset($_POST['removeAll']))
{
$aID = "0";
}
$cartSQL = "SELECT * from article where aID in ($aID)";
echo "cart sql :$cartSQL";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
$aTitle[] = $row[ 'name' ];
}
}
<form action = "" method = "POST">
<td style = "width = 200px"><input type="submit" value="Empty cart" name="removeAll"></td>
</form>
And this is the session variable from other page where I would like it to be unset upon submitting the form.
if(!empty($cartSubmit))
$_SESSION["cartSubmit"] = $cartSubmit;
else
$cart = $_SESSION["cartSubmit"];
<a href="javascript:popup('cart.php?aID=<?php if(empty($cartSubmit)) echo "$cart"; else echo "$cartSubmit";?>')">Cart</a>
Hi Guys, I am fairly new to PHP, and I recently changed my whole site to use PHP sessions, which worked fine. Then I added PHP parts in my pages that display different menu choices depending on if a PHP session exists. This also works fine, until I found that any HTML/PHP pages that have form/submits no longer work, and I get kicked back to the index.php After slow backtracking, I removed new parts, and found the forms started working again if I removed the PHP part that chooses which JavaScript file to reference, as follows from contact.php <?php if (isset($_SESSION['SESS_MEMBER_ID'])){ echo "<script language=\"JavaScript\" type=\"text/javascript\" src=\"menu_horz.js\"></script>"; } else {echo "<script language=\"JavaScript\" type=\"text/javascript\" src=\"log_menu_horz.js\"></script>"; } ?> I tried changing the echo ".." to use single quotes ' ' instead, but then it doesn't work at all then with a form or no form on the page. I assume I am doing something wrong, but I can't find any resources that give me a definitive way of referencing Javascript files. What freaked me out was only the ones with forms were an issue. I am using <?php session_start(); ?> at the beginning of every page (before any output). Other PHP code on the page is working fine. Only the above part seems to be the problem, and works too, as long as I don't submit a form. - Could it be more weirder :-) - I tried also to find a workaround, but it would mean having PHP inside my JavaScript file, but I am not sure it would work, since JS is client side, and PHP server... Essentially, I just want to run certain JS menus depending if the person is logged in or not. - Example contact.php attached Any ideas of what the problem might be with the code above? Will be grateful for any help you can give. Regards D I have two pages one is db.php and another is form.php. In form.php i have created a form which contains different fields and a submit button. But i want to write the queries in db.php. And when i click on the submit button the insert query in db.php should be executed and insert data in database but the focus remains on form.php. How can i do this??? Any Idea? Hi everyone, I have a gateway and I can submit 200 max at one time using POST. I need to send around 200,000 at a time. So, in a nut shell, I need to submit 1,000 POST without actually refreshing my page. How can I do that ? Becuz once I submit a POST, the page on my browser goes to the gateway page rather than staying on the current page. So, what I need is something like click one button do 1,000 POST and send around 200,000. Looking forward to receiving any input on this. Thanks all. Regards Hey Guys. I am working with a form that shows the grand total on the checkout page. The value of the grand total is inside a hidden field. When click on submit, the _POST array doesn't get back the last value of the grand total. I need to hit the button twice to get the last value. The weird thing is when I echo the value of the grand total it display the latest value, but not with the POST array
For example. If the grand total is $10.00 and I click on submit. It will show the POST['grand_total'] as empty. If I click on submit again it will show the grand total of $10.00.
Below is my code that I am working with. Any help would be really appreciated.
