PHP - Multiple Users Reading And Writing To Same Table - Advice

I am creating  a poll with a form using check boxes.  The resulting associative array is evaluated and   1 is to be added to values selected.  I have that part down.  I want to write the associative array to a file and the next time someone uses the form the values are read from the file, values added and then write it back to a file.  I thought it would be better to do it like this rather than query a db, add values, etc.  Any ideas on how to do this? This is the array I want to start with:
Code: [Select]
$vetservice = array(
"Korea"=>0,
"Vietnam"=>0,
"Grenada"=>0,
"Cold War"=>0,
"Panama"=>0,
"Desert Storm"=>0,
"Mogadishu"=>0,
"OEF"=>0,
"OIF"=>0
);
Values from the post array would be added to the starting value and wrote back to a text file.

Novice in way over head here!

Created a mySQL db.  populated with a bunch of data in one table.  have a simple file based login/authentication system that i've setup.

now im looking to establish some sort of process where specific users login and see specific fields.  something like if userX see fields 1,2,4.  if userY see fields 1,2,3.  SQL statements??

im completely lost on the logic how that might be best created.  hoping someone might point me in right direction...been spinning wheels.

I recently wrote a web app made with flash that communicates with php scripts on my web server(apache2). Like most others, I believe my web app is the end all be all and could potentially attract millions of users

Ok, long story short, in the long haul, there will be people using robots to communicate with my php scripts to do tasks that are in the game in order to cheat. I'd like to limit these users from hammering the server with robotic requests. I no for a fact that no human will make requests to my game more than once per two seconds or so.  So is it best for me to somehow do this type of code with php? or maybe at the apache level somehow? My flash application can detect http error status codes for each request so if any solution would cause a non standard 200, that is fine, i should be able to detect the code, and wait a couple seconds on the flash client, then do a retry hopefully

I'm lost on this one and would appreciate some help

does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

Code: [Select]
$xml='<?xml version="1.0" encoding="utf-8"?>

I do not proclaim to be a db expert, so I'm just looking for some good advice here.

I will have multiple departments that I want to be managed on the website.  Each department will only simply contain who is in charge, and all the members of that department.  In the past, I've stored all this in one table like "Departments" or whatever. 

Since each department is basically a cookie cutter of every other department, I've thought about creating a table for each department instead.  So each table name would be like "department_Hardware", "department_Software".  This way if we shut down a department, all I have to do is delete that table.

Which is better?

Hey guys.

So I'm about to start developing a Private Messaging system for a CMS that I already have set up and working fine, and I had a problem I would like to solve before I start. I would like to add a feature that allows users to send the message to one or more users at a time. Whether it be by typing in the different usernames seperated by commas in the input field or another method, I have no idea how I'd handle submitting this into the database.

I don't want it to be like a group conversation though, I want it to submit the message seperately for each user they included in the receptitents field.

Any suggestions on how to go about doing this?
Gathering it'd be like an array of some sort but I have very little experience with arrays from forms and how to seperate them.

I am basically done with my entire site. I just realized...what happens if 10 users are trying to fwrite to one file at once? that is how i store my usernames passwords signatures and all that jazz. If users cant all fwrite at once my site is not going to work AT ALL. and I might just have to give up haha. good news or bad news?

I can get files to  upload to folder and add a new row for each in to a mysql db using the code below, how do I get all the filles in one row with multiple uploads

Code: [Select]
//Check if the form was submitted.
if(isset($_POST['uploadButton'])) {
  //Specify folder path where the file is going.
  $path = 'uploads/';

  //Upload file one by one.
  foreach($_FILES['file']['name'] as $key => $val) {
    if($val != '') {
      $file_name = $_FILES['file']['name'][$key]; //Get file name.
      $file_tmp  = $_FILES['file']['tmp_name'][$key]; //Get temporary file name.
      $file = $path . $file_name;
      mysql_query("INSERT INTO images (img1) VALUES('$file');") or trigger_error('Unable to INsert: ' . mysql_error());
   




 
      //Move uploaded file
      if(move_uploaded_file($file_tmp, $file)) {
        echo 'File was succesfully uploaded to: ' . $file . '<br />';
      } else {
        //Display error message if there was a problem uploading file.
        echo 'Error uploading file "' . $key . '."<br />';
      }
echo $target_path;


        }
     }
  }

Hello,

Iv written a small script in JS to add input boxes of the type file to the page.. My problem is when i use multiple of those input boxes and submit the form the $_FILES variable only reads 1 of those boxes.. This is the javascript im using:
Code: [Select]
function addImageBox() {
var imageBoxes = document.getElementById("imageBoxes");
var tr = document.createElement("tr");
var td = document.createElement("td");
var td2 = document.createElement("td");
    var inputFile = document.createElement("input");
   
   
    inputFile.setAttribute("type", "file");
    inputFile.setAttribute("name", "image[]");
    inputFile.setAttribute("style", "width: 450px");

    td.appendChild(document.createTextNode("Image"));
    td2.appendChild(inputFile);
   
    tr.appendChild(td);
    tr.appendChild(td2);
   
    imageBoxes.appendChild(tr);
}

When i add 2 boxes (making it 3 boxes on the page in total) and count the $_FILES var after submiting the form, the count method returns 1, and when i var_dump it only 1 array is in $_FILES. Any idea's? thanks!

I'm am somewhat new to PHP and am trying to set up a website for my cousin's wedding. Her idea is to have the guests sign in with a user/pass that she provides, and once they sign in, they will be taken to a page that has their name on it (i.e. "Mr. and Mrs. So and So, you are invited...). I have come to the conclusion that I will need to make an image for each guest's name (she wants to use a font for their names that nobody will have on their computer) so what I need to know is:

How do I link each user name to their own personalized webpage, where the image of their name on the next page will change based on what username is entered? I have been told to use Sessions (which I don't yet have in this code), but I'm clueless as to how to make that work for multiple users. Where do I put the coding, what does the coding look like, etc.

Thanks in advance for any help!

The php code I have right now is this (i'm sorry it's so long, I just don't want to leave anything out that might be important):

Code: [Select]
$LOGIN_INFORMATION = array(
  'steve' => 'password',
  'rick' => 'password',
  'tom'=> 'password'
);

// request login? true - show login and password boxes, false - password box only
define('USE_USERNAME', true);

// User will be redirected to this page after logout
define('LOGOUT_URL', 'http://www.example.com/');

// time out after NN minutes of inactivity. Set to 0 to not timeout
define('TIMEOUT_MINUTES', 0);

// This parameter is only useful when TIMEOUT_MINUTES is not zero
// true - timeout time from last activity, false - timeout time from login
define('TIMEOUT_CHECK_ACTIVITY', true);

Hello PHP mates!

I am having some doubts and I am going to share them with you so maybe someone can help. Okay, I know how to make signup and login page. And here is the problem. How to make signup page for multiple types of users? For example, type A user has its own signup form, user type B also has its own and same goes for C type of user. How can I make that?

Thanks in advance PHP freaks!

I have created code that allows a table of 'X' rows and 'Y' columns to be made (the user enters the X and Y value) with each table cell being uniquely identified through name as (X, Y). Each cell is has a value of 5 and all cells needs to be filled in before the table is submitted, which is where the problem arises. How exactly would one be able to verify that every cell has been filled and then calculate the sum of all the values entered into the cells for all those which have the same X value?

The code to generate the table is as follows:


echo "<td align='left'><b>$X<b></td>";

 For($Y = 1; $Y <= $num; $Y++)  {  ?>
<td align="center"><input type="text" name="<?php echo "$X,$Y";?>" value="<?php echo 5; ?>" /> </td>
<?php   }


Thanks.
