PHP - Best Way To Pass A Lot Of User Input To Another Page?
I have a page that has roughly 100 text input fields. Once the user is done, I need to put the data in my mysql db. How do I get the data from the user input page to the php page that will process the data (e.g. process.php)?
I've done some searching and found a few possibilities use a ajax style call back to load a seperate asp page (e.g. createsession.asp) and that page set session variables that can then be read by process.php write everything to a cookie using some sort of a delimiter so that it can handle multiple variables (e.g. cookie data => var1/var2/var3/var4... write all the data to a text file and then have process.php load that file Which should I pursue? Is there a better option? Similar TutorialsI need to know how to echo multiple things on the same page. If you do understand the last line then don't read this next part. So say if had just a textbox and a submit button. I already know how to make it where they type something and they hit submit and echo's to the page. But after it echos I want to know how to make it where if they entered in another body of text it would enter on the same page right under the last echo, or the last thing they typed. So if you could help me with this or just post a code for me that would be nice. I know there has to be a better way to do this. My usernames and passwords are stored in a text file. This is what I'm doing now, and all it does is return the error statement. This is the php from after the log in page. <?php $user = $_POST["username"]; $password = $_POST["password"]; $un = "no"; $pw = "no"; $fh = fopen("users.txt","r"); while (!feof($fh)) { $line = fgets($fh); $data = explode("$",$line); if ($data["0"] == $user){ $un = "yes"; } if ($data["1"] == $password){ $pw = "yes"; } } if (($un === "yes") && ($pw === "yes")){ echo "<h4> Hello <em>$user</em>!\n<br />"; }else { echo "<h3>Your username and/or password is incorrect.</h3>\n<br />"; echo "<a href='login.html'>Return to the login page.</a>\n<br />"; } fclose($fh); ?> 2 weeks and i think i found a direction as to what i need.I worte a program and it will post to a php page. The php page needs to take the posted variables ($user) ($pass) and compair them aginst the database for existing users to return a vail or invaild login. It also needs to check and if not exits, save a 3rd and 4th variable to the the database ($serial) ($ip). Can someone giv eme guadance as to the commands i can research to accomplish this? This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=317004.0 Unfortunately I have no code for this yet cuz I don;t even know if its possible... I am programming an application that is used by a couple of stores, which could end up being a lot of stores. Anyways, the basis is that the stores would, though a separate application (and therefore separate database) create a username and password, I now want to use this username and password to do the following 1. Allow them to login to my application using the same username and password 2. I want the store the username in a session to pull tables based on the username from my database For instance, a user has the login store123, after loggin in it now pulls the information from the tables store123_items, store123_prices, store123_settings, etc. Now my database will have quite a lot of store###_tables I am, sadly, a noobie to PHP and I do recall seeing an article (somewhere on the net, and I stupidly forgot to bookmark it, knowing I would need it eventually) on how to access multiple databases easily. Now because they are both under my account I can use the same username and password for both, its accessing the MySQL username/password database and storing the info I know I am lacking on how to do it. Any ideas? Hi guys, I am trying to put together a little system that allows users to log onto my website and access there own personal page. I am creating each page myself and uploading content specific to them which cannot be viewed by anyone else. I have got the system to work up as far as: 1/ The user logs in 2/ Once logged in they are re-directed to their own page using 'theirusername.php' Thats all good and working how I need it too. The problem I have is this. If I log onto the website using USER A details - I get taken to USER A's page like I should but - If I then go to my browser and type in USERBdetails.php I can then access USER B's page. This cannot happen!! I need for USER A not to be able to access USER B profile - there is obviously no point in the login otherwise! If you are not logged in you obviously cannot access any secure page. That much is working! Please find below the code I am using: LOGIN <?php session_start(); function dbconnect() { $link = mysql_connect("localhost", "username", "password") or die ("Error: ".mysql_error()); } ?> <?php if(isset($_SESSION['loggedin'])) { header("Location:" . strtolower($username) . ".php"); if(isset($_POST['submit'])) { $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string($_POST['password']); $mysql = mysql_query("SELECT * FROM clients WHERE username = '{$username}' AND password = '{$password}'"); if(mysql_num_rows($mysql) < 1) { die("Password or Username incorrect! Please <a href='login.php'>click here</a> to try again"); } $_SESSION['loggedin'] = "YES"; $_SESSION['username'] = $username; $_SESSION['name'] header("Location:" . strtolower($username) . ".php"); } ?> HEADER ON EACH PHP PAGE <?php session_start(); if(!isset($_SESSION['loggedin'])) { die(Access to this page is restricted without a valid username and password); ?> --------------------------------------------------- Am I right in thinking it is something to do with the "loggedin" part? The system I have here is adapted from a normal login system I have been using for years. The original just checks the details and then does a 'session start'. This one obviously has to re-direct to a user specific page. To do this I used the <<header("Location:" . strtolower($username) . ".php");>> line to redirect to a page such as "usera.php" or "userb.php" Any help would be greatly appreciated! Ta Hey guys! I'm pretty new to php and starting work on a project, the first part I'm working on is a html page with text fields like this: Quote URL: Dropdown box: Submit when the submit happens I want it to post to a php page, parse whatever is inside a set of <h2> tags and print it to to the php page, also the user selects four options from the dropdown box and I need to print the string contained in the selection to the next page as well, As I said I'm pretty new but here's what i threw together so far based on references I found, but it doesn't work correctly: parse.html: Code: [Select] <html> <body> <form action="parse.php" method="post"> URL: <input type="text" name="turl" /> <br> Option: <select name="selectskill"> <option value="1">Low</option> <option value="2">Mid</option> <option value="3">High</option> <option value="4">Known</option> </select> <br> <br> <input type="submit" /> </form> </body> </html> parse.php: Code: [Select] <html> <head></head> <body> <?php $lol = $_POST["turl"]; $str = file_get_contents($lol); $DOM = new DOMDocument; $DOM->loadHTML($str); // Grab text inside the heading 2 tags $items = $DOM->getElementsByTagName('h2'); echo "option: " . $lol; // Display the content inside the second set of H2 tags echo $items->item(1)->nodeValue . "<br/>"; ?> </body> </head> </html> Thanks for all the help in advance! Hello, Firstly I am only just learning php so please bear with me.

The problem is that this code passes all the activities to the second page, where the output looks like this: Array ( [exerciseid] => Hunting, general [duration] => Array ( [Fishing from boat, sitting] => 20 [Fishing from river bank, standing] => [Fishing in stream, in waders] => [Fishing, general] => [Fishing, ice, sitting] => [Hunting, general] => ) [distance] => Array ( [Fishing from boat, sitting] => 25 [Fishing from river bank, standing] => [Fishing in stream, in waders] => [Fishing, general] => [Fishing, ice, sitting] => [Hunting, general] => ) [submit] => Add Activities ) Is there a way I can pass what the user input instead of passing everything (form validation maybe?) OK so i have a textfield and i have everything going to the database and then displaying on the page. Now is there a way to display code on the page but disable it from executing? There are some break tags in there so i would still like them to be executed on the page. Hi, what is they best way to validate user input of strings? A couple of examples would be : 1> If i wanted to check for the existance on the coma ',' character in a string and replace it with a dash '-' character? 2> To check wether a user has entered a valid ip address in the form of x.x.x.x where x can range from 0-255? I think i may need ereg/preg to do this but i have no idea about how to layout the syntax. Thanks for looking. Hi, I'm using the form data type 'date', and trying to verify it. It seems a little too complicated to check that it's in the correct format (with "/" between day/month/year), unless I use regular expression, which I don't know much about and seems feels like there's an alternate solution or it's not necessary. Currently, the script accepts DD*MM*YYYY, where * is any character, since it just strips the 3rd and 6th character and checks the day/month/year using checkdate(). I'm not even sure if this is a problem. I am giving the user a "verify" page, where I could put it in the correct format (DD/MM/YYYY), but is that enough? Feel like I'm missing something here, so any feedback would be great The code below is a function that checks to see if an email address exists in a database, if so it alerts the user. The db has one table and one field. It works fine when there is ONE record! However, if there are > 1 it doesn't work. How can I step through each record and compare it to what the user entered? Of course, $_POST is the user's value and the db record is the $myAddy value. <?php function emailLookup() { include ('file:///Library/WebServer/Documents/re_connect_scripts/emailLookup.php'); while ($row = mysqli_fetch_array($result)) { extract ($row); $myAddy = $addy; } if ($_POST["add_email"] == $myAddy) { global $lookupError; $lookupError = 'This email address is already on the list.'; global $counter; $counter++; } else { return; } } ?> Ok so I got BB Code working. Now I want to prevent Users from inserting HTML into Posts. I have the following: $PostText = mysql_escape_string($_POST['replytext']); $Replace = Array ('/(<)(.+)(>)/','/(<\/)(.+)(>)/'); $ReplaceWith = Array ('<\\2>','</\\2>'); $PostText = preg_replace($Replace, $ReplaceWith, $PostText); Now If I were to input Code: [Select] <a href=http://phpfreaks.net>Php Freaks</a>Into a forum reply it would return: Code: [Select] <a href=http://phpfreaks.net>Php Freaks When Checking the database it has: Code: [Select] <a href=http://phpfreaks.net>Php Freaks</a> Any help on solving this? I manage a simple website for a small business - nothin fancy. I'm interested using some php to enhance the site a bit. I'm looking to accept some user input and put it into a database then display it back to them on another page. What php functions would be best to use to accomplish this? Thanks for the input! Well this may sound confusing. I tried to findways to allow users to input an integer value and then assign it to a variable called $quantity, but all I could find from the internet was the usage of forms. Do I have to use forms, or can I just try this this simple syntax: $quantity = "<input name='quantity' type='text' id='quantity' size='3' maxlength='3'>"; If I do have to use forms, then how can I ever assign user's input value to a variable? Please help. I have a form a user may submit which has a text area. If the user enters "Today is the first day of the week" it will be stored in the database like that (note the carriage returns etc). If I then get that data from the table and echo it, it will print as 'Today is the first day of the week'. How can I print it so that it will retain the user's input formatting/the formatting shown stored in the table? I have a family site with a member list and a forum that both run on MySql. One of the items in the member list is the birthday. What I like to achieve is that a day or 2 before a member's birthday, a post wil be automaticly inserted in the forum, (a post that contains that this persons birthday is comming up in a few days) without any user input. I like to have this done automaticly because I don't feel like setting up a cron job for every member seperatly. There are just too many members. What I need is a script that will create a cron job or something simular the moment a new member registers and updates his profile and sets his birthday. Hello, I'm creating an application where a user can input there own CSS. The problem I'm having is understanding if this will open security holes if... 1. Users input is saved to a file called style.css 2. Each user is on their own a sub-domain from my reseller hosting plan. 3. The style.css file will be included in the page code like so: Code: [Select] <link type='text/css' rel='stylesheet' href='style.css' /> Any advice? |
