PHP - Storing Dynamic Url's

Code: [Select]
<?php $going='';
$name='<span id="name"></span>';
echo "$name";      //results : stevengoh   ---     wanted 
$going=substr($name, 1, 17);
echo "$name";   //results : <span id="going">     ----       don't want
?>
Is it possible to store in php the results of variable id="going" javascript instead of <span id="going"></span>?.

Can anyone tell me whats wrong with this:

The file uploads fine, the url however does not get posted to the database?
I added a 'or die' but it didn't execute...Do I need to move the query higher up the script?

<?php
include ('base.php');
$id = $_GET['id'];

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "imgs/pictures/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
$file = $_FILES["file"]["name"];
 $sql = "UPDATE `chillp_security`.`staff` SET `picture` = \'imgs/pictures/$file\' WHERE `staff`.`id` = $id;";
?>

Hi,
I am struggling with a form in php. I am trying to add a form by using the include function. I want to include thsi form on all pages so it would be very useful if I can save the current page name somewhere so that I can use to validate the form.

For example, this is the form I am trying to include.

<?php
if(!empty($errors))
{
if(isset($errors['sendError']))
{
echo '<p><strong class="error">There was a problem with our system please contact us directly.</strong></p>';
}
else
{
echo '<p><strong class="error">Please check the form below for errors.</strong></p>';
}
}
?>
<form action="index.php" method="post" id="form1">
<p>
<label><?php if(isset($errors['name'])) { echo '<span class="error">'; } ?>Name<font color="red">*</font>: <?php if(isset($errors['name'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['name']; ?>" name="name" size="60" align="right" style="background:#EEF5A4" />

<label><?php if(isset($errors['company'])) { echo '<span class="error">'; } ?>Company: <?php if(isset($errors['company'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['company']; ?>" name="company" size="60" align="right" />

<label><?php if(isset($errors['phone'])) { echo '<span class="error">'; } ?>Phone Number: <?php if(isset($errors['phone'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['phone']; ?>" name="phone" size="60" align="right" />

<label><?php if(isset($errors['email'])) { echo '<span class="error">'; } ?>Email<font color="red">*</font>: <?php if(isset($errors['email'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['email']; ?>" name="email" size="60" align="right" style="background:#EEF5A4" />

<label><?php if(isset($errors['enquiry'])) { echo '<span class="error">'; } ?>Enquiry: <?php if(isset($errors['enquiry'])) { echo '</span>'; } ?></label>
<textarea id="search1" id="complete" textarea name="enquiry" rows=4 cols=40 value="<?php echo $form['enquiry']; ?>" name="enquiry" size="60" align="right"></textarea>
</p>
<p>
<input type="submit" class="formbutton" value="Submit" />&nbsp;<input type="reset" class="formbutton" value="Reset" />
</p>
<p><font color="red">*</font> Denotes a required field</p>
</form>

Because I am going to use this form on all pages, I would like it to include whatever the filename is rather than index.php in the first line of the form so that when the user clicks submit, it will stay on the same page but validate the form based on the mandatory fields.

I don't know if the question is clear. I would very much appreciate any help at all.

Thank you very much.

Alright, the register/login system is fully working with sql injection, BUUUT now I want to store their IP Address. WHOLE new function that I've never dealt with before. So I need some help. Am I doing something wrong?

I have the IPadd in the database as INT(10) and then I went down to another drop down list and hit unsigned.
I feel like I'm doing something wrong with the field in the database..

{
$_SERVER['REMOTE_ADDR'] = $IPadd;
$sql = "INSERT INTO Member (username,createDate,password,firstName,email,IPadd) VALUES ('$username',NOW(),md5('$password'),'$firstName','$email',inet_aton('$IPadd'))";
mysqli_query($cxn,$sql);
$_SESSION['auth']="yes";
$_SESSION['username'] = $username;
header("Location: testing.php");
}

So, on my website, i have added a "last active" feature, so if someone is surfing the site, they can view when another users last page visit was.

so, every second, +1 is added to the $ts variable

what i have now, working and all, shows ONLY "NOW!", or ONLY "1 second", ONLY "___ seconds ago"... and so on

I have tred over, and over, and over to fix this to my liking, with more instances available, as an example, my current script will show somebody who is 13 months and 26 days inactive, just as "1 year", i want to see the "1 year, 1 month, and 26 days inactive"... or even simpler, just so it displays days/minutes/seconds/NOW!


function howlongtil($ts) {
   $ts=$ts - time();
   if ($ts<1)
       // <1 second
       return " NOW";
   elseif ($ts==1)
       // <1 second
       return $ts." second";
   elseif ($ts<60)
       // <1 minute
       return $ts." seconds";
    elseif ($ts<120)
       // 1 minute
      return "1 minute";
   
    elseif ($ts<60*60)
       // <1 hour
       return floor($ts/60)." minutes";
   elseif ($ts<60*60*2)
       // <2 hour
       return "1 hour";
     elseif ($ts<60*60*24)
       // <24 hours = 1 day
       return floor($ts/(60*60))." hours";
     elseif ($ts<60*60*24*2)
       // <2 days
       return "1 day";
     elseif ($ts<(60*60*24*7))
       // <7 days = 1 week
         return floor($ts/(60*60*24))." days";
   elseif ($ts<60*60*24*30.5)
       // <30.5 days ~  1 month
       return floor($ts/(60*60*24*7))." weeks";
     elseif ($ts<60*60*24*365)
       // <365 days = 1 year
       return floor($ts/(60*60*24*30.5))." months";
   else
       // more than 1 year
       return floor($ts/(60*60*24*365))." years";
};


anyone know how?

Im making a application but many users can access it at the same time, also the data that needs to be stored into the database in 3 parts firstly the user will enter some details the comany will fill out the reamining details and the user will then accept or decline the companies proposal. The issue im havign will it be easier to just store all of this information into session variables and then save them into the database at the end when all of the details are ready ?

Thank You

Hey guys,
What would you recommend to store db values for later?

the only thing I can come up with is doing it this way:

$result = mysql_query("SELECT * FROM users WHERE name='$user'");
while($row = mysql_fetch_array($result))
{
}
  {
and then using the $row['dbvariable'] later

is that the best way?

Hello all, I'm having some problems with a script ive written which is designed to allow me to send a message to all the users of my site.

the form works fine, the SQL works fine but im having a problem with storing php variables and outputting them in the message.

The form has a field named "allmessage" which is where i'll type my message, I'll type something like

"Hello $Name" and store the text as

$allmessage = $_POST['allmessage'];

example script


//loops through each member
    while ($row=mysql_fetch_array($sql)) 
    {
    
    //sets variables
    $ID=$row['ID'];
    $Name=$row['MemberName'];
    $Email=$row['Email'];
 
    $content_type = 'Content-Type: text/plain; charset="UTF-8"' ;

    mail($Email, $allsubject, $allmessage, $content_type);
    }
//loop ends send us a copy of the mail
mail("me@me.com", $allsubject, $allmessage, $headers );


Now what I want to be outputted in the email is "Hello John" or "Hello Paul"

but what I get is "Hello $Name".

Any ideas?!

Hi, when a user logs out, I want to store the last activity in for the user. I have a db table users:

userID  userName  userPassword lastSession     lastActivity
=====  =======  ==========  ========    =======
1            bob            password         2011-08-09   About.html
2            dre             passwords       2011-09-23   Home.php


here is logout script:
===============
Code: [Select]
<?php
//run this script only if the logout button has been clicked
if(array_key_exists('logout', $_POST)) {
        require("connect.inc");
$username=$_POST["username"];
$updateLastSessionQuery=mysql_query("UPDATE users SET lastSession=NOW() WHERE userName='$username'");

// end session and redirect
//empty the $_SESSION array
    $_SESSION = array();

    session_destroy();
header("Location: xmlShredderLogin.php");  
    exit;
}//END IF for when logout submitted
?>

here is Index.php:
=============
Code: [Select]
<?php
session_start();
if(isset($_SESSION["isAuthenticated"])) {
require("logout.inc.php");
$username=$_POST["username"];
//print $username."<br />";
print '
<html>
<head><title>Home</title></head>
<body>
<form id="logoutForm" name="logoutForm" method="post" action="">
<input name="logout" type="submit" id="logout" value="Log out" />
<input type="hidden" name="usernameHidden" value='; print$username; print '/>
</form>';
mysql_connect("localhost","root");
mysql_select_db("someDB");
$getUserInfoQuery=mysql_query("SELECT lastSession,lastActivity FROM users WHERE userName='$userName'");
$getUserInfo=mysql_fetch_assoc($getUserInfoQuery);
print "Last session: ".$getUserInfo["lastSession"]."<br />";
print "Last activity: ".$getUserInfo["lastActivity"]."<br />";


Let's say the last page the user is on is Index.php, so what do I use to track the last page they are on?? I can't user a form b/c if I have to type in the last activity, that's nonsense! So far I have only figured out how to store the current time in last session (but this doesn't work either).

I just want to track the last page and then have a switch such as:
switch(type)
case 1:
$lastActivity="About.html";
case 2:
$lastActivity="somethingelse.php";


Any help much appreciated!

Hey,

I am a bit of a noob at php/mysql and trying to be clever(emphasis on trying).

I want to pull some php/html code from a database in mysql, whilst it does display the html, the php does not.
Can this even be done? Is it going to cause me issues later on?

Code: [Select]
[php]
<?php
    $query = "SELECT * FROM pages";
    $result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($result)){
$body = $row["body"];
echo $body;
    }?>
[/php]
Any help would really be appreciated.

I would like to store weekly reports into documents.  I am familiar with storing data to a regular text document, but it does not keep bold text, tables and so forth.  Are there any other documents that would not be to hard to output to such as .pdf, .rtf, .doc, etc.?

I've attached the current format we are using in excel.  Now that I have things automated in php, I would like to output to a document with almost identical formatting.  And how can I keep it on 8 1/2" x 11" pages without it splitting data or tables between two pages?

Thanks,

Jake

Hi,

I have a XHTML/PHP page that loads a PHP file each couple of seconds for building up the page. The PHP file should retreive data that keeps changing.

What would be the best way to store and retreive the data? Obviously i can do this with a database but that will put a lot of stress on the server as each user keeps polling the database. So i was looking into other methods of doing this.

I have tried doing this with a plain text file and CSV files using fwrite to put the initial data into a file with separators. Then retrieving that file and explode it into a multidimensional array again. I am unsuccessful here to assign the key values to the new array. I have also tried many snippets for this but these where also not working properly for me.

Maybe XML is the key, i didn't really delve into it yet but it seems i have to get extra programs or parser to actually write and change files? But then again i can't find any working tutorials on how to put multi dimensional strings back and forth between PHP and XML.

So what needs exactly to be done. Well i'm creating a game where you can fight each other with 4 units on a turn base. The units have a speed stat that determines when it's there turn to act. Like if (unit 1) has 3 speed and (unit 2) 5 speed they will move like this on the time line (unit 1) -> (unit 2) -> (unit 1) -> (unit 1) -> (unit 2). So the plan is each time the user acts with a unit to increment it's speed by the base value. A script will run each time picking up the next unit in line.

The PHP page does a check on which player the unit belongs to and if that matches the players ID it will sent the necessary information. The other player will get something like "not your turn".

Tx,

Hello everyone

I wonder if you could help me.

I want to create a function called


<?php
function mythings($what)


Which would allow me to pass an ID number to, such as


<?php
mythings(5419);


What I want to do with that function is store the ID numbers of the past 6 items I have viewed, but I want to store each item as a SESSION once it has been passed.

So essentially I would end up with the following 6 SESSIONS


<?php
$_SESSION['item1'];
$_SESSION['item2'];
$_SESSION['item3'];
$_SESSION['item4'];
$_SESSION['item5'];
$_SESSION['item6'];


So the "item1" SESSION would be the latest item ID passed through the function

But then if I then passed a new ID through the function, that new ID passed would then become

$_SESSION['item1'];

and the current SESSION

$_SESSION['item1'];

would become

$_SESSION['item2'];

and

$_SESSION['item2'];

would become

$_SESSION['item3'];

and so on.

This means I can do a list such as

<?php
print "Item 1".$_SESSION['item1']."<br>";
print "Item 2".$_SESSION['item2']."<br>";
print "Item 3".$_SESSION['item3']."<br>";
print "Item 4".$_SESSION['item4']."<br>";
print "Item 5".$_SESSION['item5']."<br>";
print "Item 6".$_SESSION['item6']."<br>";
?>

Does that make much sense? Can anyone help.

Thanks very much all

John

Hey,

I know this questions get asked a lot but here is a different version of it.

What is a simple and secure method for storing data/passwords? I know there is a lot of debate in this subject but I run a browser game off my server and just want the data to be encrypted.

is this good enough or is this easy to crack?

Code: [Select]

<?php
 $password = 'abcdefg';
 $salt = 'whateversecrethash';
 $pw_hash = md5($salt.$password);
?>


or I just found this tutorial is this up to date and actually a good method?
