PHP - Keeping Dates As Text

I've got a weird problem which affects only Safari browsers.
Site A offers user a login page and validates the credentials by calling HTTPRequest on site B ( this call starts new session, user password is checked and session id stored in the db).
If user login details are OK, site A redirects user to site B ( different domains and physical boxes).

It worked well before the last Safari update (5.0.1) - when user login is being checked, server B creates session X, after the redirect, session_start() creates absolutely different session Y.

All sessions are maintained by cookies only (SSL).


Any ideas how to maintain the same session during the redirect?

Thanks!

What are the different ways you can keep a User "logged in"?

From what I *vaguely* recall from a year or two ago when I read a whole hoard of PHP books, you commonly use cookies and sessions.

But I'm asking this more from an OOP standpoint than a PHP standpoint.

Let's say I have a User record in my database, and a User comes along and attempts to log in.

In OOP terms, I would think you'd call some class to help log them in, and upon successfully logging in, you would "load" the User object into memory and set the "LoggedIn" field to "True". Then as long as that field was set in their object, they could surf all over the place and do things like change their account and buy things.

Is that how you would do it in OOP?

I've finished designing my website home page and I've now moved on the some of the other pages, I want my header and footer to appear the same on every page. I've tried this basic way of linking the same stylesheet that makes up my header/footer in the second HTML file (already used in the homepage):   <link rel="stylesheet" href="footer.css" type="text/css"/>
<link rel="stylesheet" href="header.css" type="text/css"/>   I now understand that this isn't going to work. Would a server-side scripting language be my best bet here? Something like PHP? If so, would anyone be able to link me with an article on how I could do this in PHP, I presume with the include function? I've had answers elsewhere but this, for me, isn't working:   "You are currently only linking the css for the header and footer. If you want to include the html as the same, create two separate files header.php and footer.php, then include them into each webpage. <?php include('path/to/header.php');?> // in the location you want the header in the page
<?php include('path/to/footer.php');?> // in the location you want the footer   Essentially, you're making partials and placing them wherever you want them"     Any help would be greatly appreciated.

What is the best way to keep track of a User's (real-time) online status?

Right now I have a Log In script and I set the status in the User's Session, and then "pass" that status from page to page with session_start();.

However, the problems with this approach include...
1.) A User is idle for hours or days and thus not really online
2.) A User leaves my site and thus is not really online  (Or does closing the window change that?)

I want a fairly accurate and real-time reading of whether or not a User is actively using my site so I can set their "Online Status" icon as green (online) or yellow (in active) or grey (offline).

Any idea how to accomplish that so I have monitoring like you'd see on an Instant Messenger App?

Thanks,

Hi Guys   I'm building a php application where users must login to access a set of private images. The images display as a set of thumbs to the user, which they can click to download the full size image. so I need to read a whole batch images (500+) of them from a directory.   So I'd like some advice on the best way to:   1) Keep files from being world readable.
I know you could probably achieve this using htaccess or storing them outside the document root but which is best given that I need to read a whole directory with hundreds of images? 2) How to access the images If it turns out storing the images off document root is the way to go, what's the most efficient way to read a directory off the doc root and access the individual images (readfile for instance)?   Thanks in advance,   Drongo  

I am trying to take a specific link from my site and place it into my database. I only want links starts with CORPSEARCH.ENTITY_INFORMATION?p_nameid=

Can someone point me in the right direction here?


Code for this is below:


// make the cURL request to $target_url
$html= curl_exec($ch);
if (!$html) {
   echo "<br />cURL error number:" .curl_errno($ch);
   echo "<br />cURL error:" . curl_error($ch);
   exit;
}

// parse the html into a DOMDocument
$dom = new DOMDocument();
@$dom->loadHTML($html);

// grab all the on the page
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");

for ($i = 0; $i < $hrefs->length; $i++) {
   $href = $hrefs->item($i);
   $url = $href->getAttribute('href');
   $sql="INSERT INTO links(cid, nlink)VALUES('$i','$url')";
   $result=mysql_query($sql);
   echo $result;
   echo $url;

I need to create the unique SKU (Stock Keeping Unit) name for each products mixed with
product.id,product.name,product.category and product.brand. There is no problem to do it,

i.e.: SKU for a product with

id=13,
name=Bio Clean green and
category=INSECTS KILLERS
brand=HARPIC

becomes : BI-IKHA0013

This is how I tried:

$inm = "Bio Clean green500ml";
$cnm = "INSECTS KILLERS";
$bnm = "HARPIC ";

echo SKU_gen($inm, $cnm,$bnm,20).'<br>';


function SKU_gen($pname, $cat=null, $brand=null, $id = null, $l = 2){
    $results = ''; // empty string

    $str1 = array_shift(explode(' ',$pname));
    $str1 = strtoupper(substr($str1, 0, $l));

    $str2 = array_shift(explode(' ',$cat));
    $str2 = strtoupper(substr($str2, 0, $l));

    $str3 = array_shift(explode(' ',$brand));
    $str3 = strtoupper(substr($str3, 0, $l));

    $id = str_pad($id , 4, 0, STR_PAD_LEFT);

    $results .= "{$str1}-{$str2}{$str3}{$id}";
    return $results;
}

But this function is not working as expected when category of brand values become NULL.

I have a directory in public WWW. The files throughout the directory have many PHP includes amongst themselves. For example, the file "registration.php" begins with require('../parameters.php');

The directory is complex, like this:

/Public WWW directory/
        /My_Directory
            parameters.php
            another_reg.php
                /app
                    files.inc
                     files2.inc
                    /morefiles
                    another.inc
                    another2.inc
                    /css
                mycss.css
                /pages
                config.php
                registration.php
            
My question: I want the entire directory moved out of reach above the public WWW, but I want "registration.php" to go into the public WWW.

How would I do that without breaking all the include paths? (I know the solution is probably a one-liner involving __DIR__  ... but I can't seem to code it so it works).

Thank you!!

 

Hello, I am having an issue where PHP nulls the donation amount after multiple form submits. Here is a synopsis of what is happening.

1: User enters donation amount and clicks 'submit'
2: Is taken to a confirmation page where they must agree to terms
3: User fails to agree to the terms, the page is reloaded with an error message, and the donation amount is set to null

I want to make the donation amount display despite multiple confirm page reloads. How would I do this?

Here is the site to test it yourself. Ignore the steamid input and check "do not change my rank upon donation" to test.

Please note: If you use IE, the formatting is messed up, that is a problem I will look into later

Hi   I want to get my <footer> to appear at the bottom of my page, but I dont want it to be fixed there.   So if the middle contents of a page is very short, the <footer> will be visibled at the bottom of the browser, but if the page contents is long, then the <footer> would just disappear at the bottom of the contents.   Can this be done?   Thanks

This sounds like it should be pretty simple but I've looked for a while and I'm having trouble finding an answer.  What I have is a simple table with 3 columns with predetermined widths.  When the text that is queried from the database is inserted into the table, and the text string is longer than the column width, it pushes the text to a second line, which throws the whole table out of whack.  Instead, I want the text to be cut off before going to the next line.  For example:

This is what is happening:

This is a sample string of
text.

This is what I'm trying to do:

This is a sample string...

Can anyone tell me where to find the solution to this problem?

Not that it's needed, but here is some simple code that I'm working with:
Code: [Select]
<?php

$message = "This is a sample string of text.";

echo "<table width=\"150\" height=\"20\"border=\"0\" cellspacing=\"0\" cellpadding=\"0\">";
echo "<tr>";
echo "<td width=\"50\" height=\"20\" align=\"left" valign=\"top\">Column 1</td>";
echo "<td width=\"50\" height=\"20\" align=\"left" valign=\"top\">Column 2</td>";
echo "<td width=\"50\" height=\"20\" align=\"left" valign=\"top\">$message</td>";
echo "</tr>";
echo "</table>";

Hey, This is my first day with PHP and I'm given an assignment by my professor. Assignment is a very basic game, all i have to do is give 2 random numbers, and add them, and check if the user has submitted the correct answer.    So i thought like this;   1-    first php file generates two random numbers 1.1- user submits the sum of those numbers   2-    second php file, gets the sum of the random generated numbers and checks if the submitted value is right.   I've come up this far;   <?php
echo "<html><head><title>calculation game!</title></head><body>";
echo "<h1>first number is</h1>";
echo (rand(100, 450));
echo "<h1>and the next number is</h1>";
echo (rand(100, 5000));
echo "<h1>now add the numbers and submit your output here!</h1>";
echo "<form name = \"myfirstform\" action  = \"formprocess.php\" method = \"PO$
echo "Enter data<br>";
echo "<input type = \"text\" name = \"firstdata\">";
echo "<br> <input type= \"submit\" value = \"Let's check!\">";
echo "</form>"; ?>      Now my problem is about; how can I keep those generated numbers and add them up. I've been digging all through the internet for syntax and php scripts, but I couldn't find an answer that helps me.    Thanks in advance.

Currently, I'm trying to write a contact form, and perhaps I'm overcomplicating it, but I have a public variable called $EquationAnswer that stores the answer to the Captcha method (randomised maths question) and whenever the page reloads, it creates a new instance of the Contact class, which then erases the value that has been stored in that variable.   What I'm trying to achieve is keeping the value stored even after a new instantiation of the class. I remember from a class at University that static was a way to do this, but this was in C#.

<?php

class Contact
{
	public $EquationAnswer;

	public function CaptchaCreation()
	{
		$SignArray = array('+', '&times;', '-');

		$NumberOne = rand(1, 9);
		$NumberTwo = rand(1, 4);

		if($NumberOne < $NumberTwo)
			$SignIndex = rand(0, 1);
		else
			$SignIndex = rand(0, 2);

		$Sign = $SignArray[$SignIndex];

		$EquationString = $NumberOne." ".$Sign." ".$NumberTwo;

		switch($Sign)
		{
			case "+":
				$Answer = $NumberOne + $NumberTwo;
				break;
			case "-":
				$Answer = $NumberOne - $NumberTwo;
				break;
			case "&times;":
				$Answer = $NumberOne * $NumberTwo;
				break;
		}

		$this->EquationAnswer = $Answer;

		return $EquationString;
	}

	public function EchoContactForm()
	{
		$CaptchaMessage = $this->CaptchaCreation();

		echo "<form method='POST' action=''>\n\n";
		echo "\t\t\t\t\t<table>\n\n";
		echo "\t\t\t\t\t\t<tr><td>Name: </td><td><input type='text' name='name' /></td></tr>\n";
		echo "\t\t\t\t\t\t<tr><td>Email: </td><td><input type='text' name='email' /></td></tr>\n";
		echo "\t\t\t\t\t\t<tr><td>Subject: </td><td><input type='text' name='subject' /></td></tr>\n";
		echo "\t\t\t\t\t\t<tr><td>Message: </td><td><textarea rows=5 name='message'></textarea></td></tr>\n";
		echo "\t\t\t\t\t\t<tr><td>What is: ".$CaptchaMessage."?</td><td><input type='text' name='captcha' /></td><td></td></tr>\n";
		echo "\t\t\t\t\t\t<tr><td colspan=2 style='text-align: right'><input type='submit' name='submit' value='Send' /></td></tr>\n\n";
		echo "\t\t\t\t\t</table>\n\n";
		echo "\t\t\t\t</form>\n";
	}

	public function ContactFormValidation($Name, $Email, $Subject, $Message, $CaptchaInput, $CaptchaAnswer)
	{
		echo $CaptchaAnswer;

		$ErrorsArray = array();

		if(strlen($Name) == 0)
			array_push($ErrorsArray, "You must provide a name.");
		if(strlen($Email) == 0)
			array_push($ErrorsArray, "You must provide an email.");
		if(strlen($Message) == 0)
			array_push($ErrorsArray, "You must provide a message.");
		if(strlen($CaptchaInput) == 0)
			array_push($ErrorsArray, "You must provide an answer to the maths question.");
		if($CaptchaInput != $CaptchaAnswer)
			array_push($ErrorsArray, "Incorrect captcha answer.");

		if(count($ErrorsArray) > 0)
		{
			echo "There are ".count($ErrorsArray)." Errors: <br />";

			foreach($ErrorsArray as $E)
				echo $E."<br />";
		}
		else
		{
			return true;
		}
	}
}

?>

^ That's the Contact class, and the main function that I want to focus on is the last one, "ContactFormValidation()".   From the contact form page (which is within a template), I want it to send the EquationAnswer variable to that function so that it can compare what the user has input.

<?php

//Instantiate the contact class
include './inc/PHP/classes/ContactClass.php';
$ContactClass = new Contact;

if(!isset($_POST['submit']))
{
	$ContactClass->EchoContactForm();
}
else
{
	$NameInput = $_POST['name'];
	$EmailInput = $_POST['email'];
	$SubjectInput = $_POST['subject'];
	$MessageInput = $_POST['message'];
	$CaptchaInput = $_POST['captcha'];
	$CaptchaAnswer = $ContactClass->EquationAnswer;

        //Tried echoing out what is in the variable but it produces nothing because the contact class is a new instance.
	//echo $CaptchaAnswer;

	if($ContactClass->ContactFormValidation($NameInput, $EmailInput, $SubjectInput, $MessageInput, $CaptchaInput, $CaptchaAnswer) == true)
	{
		//Mail function
	}
}

?>

Any help would be appreciated.   Cheers.

I have this image upload script he

<?php
if (isset($_POST['submit'])) {
    $j = 0; //Variable for indexing uploaded image 
    
	$target_path = $_SERVER['DOCUMENT_ROOT'] . "/ubergallery/multiple_image_upload/uploads/"; //Declaring Path for uploaded images
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable
        
		$target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];//set the target path with a new name of image
        $j = $j + 1;//increment the number of uploaded images according to the files in array       
      
	  if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
                && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
            } else {//if file was not moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
}
?>

This script also uses javascript for multiple uploading of images.   I am looking to add a query to this where I am looking to have the image file names stored in the database.   The original image file name should get stored as well, yet the file name itself should get a unique id.   I may have to build this query inside this upload script. I was wondering if I can keep that separately with Object Oriented Programming, if somebody just could show me "how it could look like", when it comes to having this done with Object Oriented Programming, I would appreciate it a lot.  

I am wondering if there is an easier / better way to keep my development and test databases in synch.   When I develop, I may add tables or fields to existing tables. When I upload from the development server to the test server I can check and make sure that I include all of the programs that I have edited by using the filesystems last modified date. However, I keep track of new and changed tables in MYSQL manually. Is there an easy way, that I am just missing, to see last modified dates for tables within a db? Is there some other strategy I should be using. I hate missing a table and having the test server give errors on code I debugged once on the development server.
