PHP - Moved: Checking Which Version Of Ie User Is Running

This topic has been moved to Third Party PHP Scripts.

This is something that has intrigued me, that has only recently surfaced when viewing the forum.

Which of the following methods of authenticating that a user exists would be better/faster/ect?

Example 1 - Fetching Row Data
<?PHP
  $username = 'LoserVille';
  $password = 'password';

  $myQuery = mysql_query("SELECT account_id FROM user_accounts WHERE username = '$username' AND password = '$password'");
  $myQuery = mysql_fetch_assoc($myQuery);

  if($myQuery) {
    /*### User Exists ###*/
  } else {
    /*### User Does Not Exist ###*/
  }
?>


Example 2 - Fetching Number of Results
<?PHP
  $username = 'LoserVille';
  $password = 'password';

  $myQuery = mysql_query("SELECT account_id FROM user_accounts WHERE username = '$username' AND password = '$password'");
  $myQuery = mysql_num_rows($myQuery);

  if($myQuery >= 1) {
    /*### User Exists ###*/
  } else {
    /*### User Does Not Exist ###*/
  }
?>


Just looking for some insight, not really a problem

Hi,

I'm trying to figure out the best way to determine if a user is currently downloading a file from my website.
The way my site works, is the user waits 30 seconds and views an ad. After the timer is up the download becomes available.
I heard that I could probably use a timestamp or something of the sort. I've read up on it but not sure how I could go about this.

I've got a page that allows users to upload a file (pdf, jpg, gif png). The user must be logged in in order to upload something. I have a query that checks if the user has already uploaded a file with the same name as the name of the file they are trying to upload.
If they have not uploaded the file yet, the file uploads and they get a "Success" message. If the file has already been uploaded by the user, they will get the message, "You have already uploaded that file".
When the query goes through, the message that shows is, "You have already uploaded that file". I ensured the file was not already in the database, and it still shows this error. I tried changing the if statement to say:

if ($duplicate==0)

instead of:

if ($duplicate!=0)

but it always shows the same error. Any ideas of what could be wrong with my code?

my sql table looks like:

Field     Type      Null     
id    int(11)    No          
userid    int(11)    No          
artist    varchar(50)    No          
title    varchar(50)    No          
file    varchar(2083)    No          
uploaded    varchar(3)    No          

Code:

<?php
session_start();

if (isset($_SESSION['username'])){

$username = $_SESSION['username'];
$submit = $_POST['submit'];

include_once('inc/connect.php');

$uploadsql = mysql_query("SELECT * FROM `users` WHERE `username`='$username'"); 
$uploadrow = mysql_fetch_assoc($uploadsql); 

$userid = $uploadrow['id']; 
$folder = "sheets/fromusers/";

if (isset($submit)){

// Name of file
$name = $_FILES["location"]["name"];
// Type of file (video/avi) or image/jpg, etc
$type = $_FILES["location"]["type"];
//size of file
$size = $_FILES["location"]["size"];
//stores file in a temporary location
$temp = $_FILES["location"]["tmp_name"];
// if there is an error
$error = $_FILES["location"]["error"];

$artist = strtolower($_POST['artist']);
$title = strtolower($_POST['title']);

// Check if fields are filled in

// If file is This File.pdf
// Then $ext is now equal to pdf

Below I am checking a user level and if they are  level one they see some of the form, and if level two they see additional options.

What they have already filled out is to show in the text field. Before I was doing the user level check it worked fine. Even now if something is put in a field it saves in the DB but it will not show in the fields on the form.

// Everyone sees
          <tr>
            <td><input name="" type="text" id="" value="<?php echo $row_settings['FieldA']; ?>">
          </tr>
        <tr>
            <td><input name="" type="text" id="" value="<?php echo $row_settings['FieldB']; ?>">
          </tr>
// Check if level two and display if they are.
    <?php }
if (checkUser()) {
?>
        <tr>
            <td><input name="" type="text" id="" value="<?php echo $row_settings['num1']; ?>">
          </tr>
        <tr>
            <td><input name="" type="text" id="" value="<?php echo $row_settings['num2']; ?>">
          </tr>
        <tr>
            <td><input name="" type="text" id="" value="<?php echo $row_settings['num3']; ?>">
          </tr>

     <?php } ?>
// Additional things everyone sees even level one.
        <tr>
            <td><input name="" type="text" id="" value="<?php echo $row_settings['num4']; ?>">
          </tr>
          <tr>

So even <?php echo $row_settings['num4']; ?> will not show/work after the <?php } ?>

Any thoughts? Thanks in advance everyone.

I'm trying to set up a multipage registration script. It's tuff! I've set up some basic scripts to distribute variables into the correct tables from previous forms using a session. But I want the script to check the input from form one is valid before it moves on to form 2.

Here are my scripts:

I've also got form3.php and process_forms.php(that's where I mysql_real_escape_string and input the data) but that's probably not relevant. How would I get this to work? Are there any sites I should look at that you'd recommend? Any help appreciated.

Hey guys and gals!

This is my first post here and needing a bit of help with my php code! So here is the deal, i have 3 tables in ms sql 2000 which i will be using on this project.

i have an employee table that has the regular information such as:

TABLE employee( uniqueid, employee_number, lastname, firstname, dob, address, city, state, zip )

TABLE employee_docs( uniqueid, employee_number, doc_type int, date_received, date_issued, date_expired )

TABLE doc_type(uniqueid, description, valid_month)


so basically from the employee_doc table, the doc_type column is an int and will have the description of the document as well as valid month column which will tell you how long the document type is valid until. the Description gives a brief description of what the product is. The uniqueid is used as what ever number is chose from the employee_docs table will represent the document type from table doc_type.

ok so now that i gave a brief explanation of the tables i am working with, I can tell you what i need.

i need a php page that will display:

employee number, lastname, firstname, doc_type, date_received, date_issued, date_expired.

Code: [Select]
select pn.empnum as employeeid, (pn.lastname + ', ' +  pn.firstname)as [Full Name],
dt.description as doc_type,
formatDate(pd.received) as [Date Received],
formatDate(pd.expired)as [Date Expired],
formatDate(pd.issued) as [Date In Service]

from personnel_document pd
left join document_types dt on (dt.uniqueid = pd.doc_type)
left join personnel pn on (pd.empnum = pn.empnum)

where pd.empnum = '$EmpNum'
now, I went ahead and did this for the html part:
 
Code: [Select]
<table border=0>
           
            <tr>
                    <td height=20px weight=1px valign=bottom><span class=underline>DESCRIPTION</span></td>
                            <td height=20px weight=1px valign=bottom><span class=underline>DATE RECEIVED</span></td>

I am now doing the the sql statement to insert into my db but i am stuck.
i basically want to get the information that the user enters for each field and save it on the employees profile.

$querydoc = "update    personnel_document
                      set empnum = '$EmpNum' , doc_type = ???, date_received = ????, date_expired = ????, date issued = ???
         where empnum = '$EmpNum' ";

The problem is that since each description has a different variable im not sure how to update it.... would I have to create a new update for each description? also I hard coded the name of each description but i believe it is better if i echo the description name from the db as i cant use taht as the doc_type... i am pretty confused, if anyone has a better way of doing this i would really appreciate it!

eventually i also want to make sure that the description is expired to to with the fields I have there and promp the user of something that is expired. Once again, any help given is much appreciated!!!

Hi all,

But of a PHP newbie so treat me nice but this one is driving me nuts 

I have the exact same login.php file running on two different servers and they have slightly different versions of PHP installed as follows:

1. PHP Version 5.0.4 - version http://www.trafficpaymaster.com/tpm/phpversion.php
2. PHP Version 5.2.15 - version http://www.dentistsinflorida.org/tpm/phpversion.php

The login works fine on the first server from he
http://www.trafficpaymaster.com/tpm/login.php

Email: test@test.com
Pwd: test

But try it on the second server he
http://www.dentistsinflorida.org/tpm/login.php

Using the same email and password (which is correct) it just loops round not letting the user into the main script at index.php

Question:  Why?
What have I got wrong for that later version of PHP?


Many thanks guys.
