PHP - Construct Parameter From Array

PHP Warning:  file_exists() expects parameter 1 to be string, array given in /home/mysite/public_html/display.mysite.com/wp-content/themes/mytheme/form.php on line 9

PHP Warning:  file_exists() expects parameter 1 to be string, array given in /home/mysite/public_html/display.mysite.com/wp-content/themes/mytheme/form.php on line 13

I have a form that is having some issues and in the error log I see a bunch of these warnings. What is wrong with this??   I numbered the offending lines below (lines 9 & 13)   Thanks for any help on this.

function CheckExistance($VUrl)

{

/*9*/    if ( file_exists($VUrl) )

        echo $VUrl;

/*13*/    elseif ( file_exists(str_replace('www.display.mysite.com','www.display.com', $VUrl)) )

        echo str_replace('www.display.mysite.com','www.mysite.com', $VUrl);

    else

        echo str_replace('www.mysite.com','www.display.mysite.com', $VUrl);

}

Problem:
"Warning: extract() expects parameter 1 to be array, null given in C:\x\xampp\htdocs\pages\user_personal.php on line 32" - error also found on lines 33 and 38.
and none of the information is displayed.

Goal: I'm trying to retrieve profile information and multiple user inserted pictures and display the pictures through a while loop from one query.

Yet I am getting said error message.  What am I doing wrong?

Struggling to get my head round this, may be really simple and im just not seeing it because im tired, but why does the following code generate two files?

<?php
class x {
var $val = '';
var $cfg = array();

public function __construct($somevalue) {
$this->val = $somevalue;
file_put_contents(rand(0,1000).'init','null');
}

public function addcfg($name,$value) {
$this->cfg[$name] = $value;
}
}

//Create 
$somevalue = 'abc';
$x = new x($somevalue);

//Add database config
$x->addcfg('name','dbname');
$x->addcfg('user','dbuser');
$x->addcfg('pass','dbpass');

hi, cane somebody please explain how to use the declare contruct of PHP 
some code snippets may help..thanks in advance

Hello,   I recently posted here about an issue I was having with my database orientated products page.   I have now run into another problem where say if, /db.php was typed or /db.php?p=IDoNotExist was typed, it returns blank.   I have in my code the desired content to be displayed, but it just doesn't seem to want to make a show.   I was also wondering if it is possible to show different content for whatever the URL is, so for no parameter, the content about the products, and a non existent one, maybe "Product not found"?   Here is my code:

<?php
	$db=mysql_connect  ("localhost", "webwibco_charlie",  "Hello123") or die ('I cannot connect to the database  because: ' . mysql_error()); 
	$mydb=mysql_select_db("webwibco_products"); 

	include("header.php");

	$status = htmlspecialchars( @$_GET ['p'] );

	if ($status == "floorpuzzles") {

		     echo "<h1>Our Floor Puzzles</h1>";
		$sql="SELECT  ID, Name, Tags, Description, Category FROM products WHERE Category LIKE '%" . FloorPuzzles .  "%'"; 
		$result=mysql_query($sql); 
		while($row=mysql_fetch_array($result)){ 
			$Name  =$row['Name'];
			$ID  =$row['ID']; 
			$Description  =$row['Description'];  
			echo "<div class=\"box\">";
			echo "<h1>$Name</h1>";
			echo "<div class=\"floorbox\"><a href=\"?p=$ID\"><img src=\"images/products/catalogue/big/floorpuzzles/$ID.jpg\" class=\"small\"></a></div>";
			echo "<h2>$Description</h2>";
			echo "</div>";
		}
?>
<?
}else{



	if ($status == $_GET["p"]) {
		$sql="SELECT  ID, Name, Tags, Description, Pieces, Size, Barcode, Category FROM products WHERE ID = '" . $_GET['p'] .  "'";   
		$result=mysql_query($sql);   
		while($row=mysql_fetch_array($result)){  
			$Name  =$row['Name'];
			$ID  =$row['ID']; 
			$Description  =$row['Description']; 
			$Pieces  =$row['Pieces']; 
			$Size  =$row['Size']; 
			$Barcode  =$row['Barcode'];   
			echo "<div class=\"1\">";
			echo "<h1>$Name</h1>";
			echo "<div class=\"bigbox\">";
			echo "<div class=\"floorbox\"><img src=\"images/products/catalogue/big/floorpuzzles/$ID.jpg\" class=\"big\"></div>";
			echo "</div>";
			echo "</div>";
			echo "<div class=\"2\">";
			echo "<p>Puzzle Pieces: $Pieces</p>
				  <p>Puzzle Size: $Size</p>
				  <p>Barcode: $Barcode</p>";
			echo "</div>"; 
		} 
		}else{
?>
<?
			echo"<h1>Our Products</h1>
				<p>Our jigsaw puzzles are hand cut by skilled craftsmen and therefore each one is unique with self-correcting pieces. There is a strict quality control process at all stages by our highly experienced staff. The puzzles are durable and provide fun and excitement, enhancing learning and a child’s development.<p>
				<p>All of our jigsaws are made using materials from sustainable resources grown in managed forests. Where possible we support companies in the UK and source our components locally, most of our suppliers are in the East Midlands, many in Derbyshire and Nottinghamshire. We keep packaging to a minimum and take our environmental and ethical responsibilities very seriously.</p>
				<p>Reducing waste and recycling was a way of life for us before it became fashionable. We are constantly searching for new ideas and consult teachers when developing our jigsaws, which are often used within the national curriculum.</p> 
				<p>As well as making our own range, we manufacture for leading suppliers to the education market. Check for \"Made in Britain\" and it is probably made by us.</p>

				}}

include("footer.php");
?>

The final echo is what I wish to be displayed on the URL without or with an invalid parameter.   Here is my site URL: http://www.webwib.co...saws/search.php (note that only the "Floor Puzzles" category has content within it).   Thank you in advance for assistance.

I have the following code just to insert a username and hashed password into the database but somehow I am getting this error and I couldn't find out where I am doing it wrong...can someone please give me a hand?   I tried it in two ways and both errors... the first few lines are just connecting database which worked fine and a password.php so I can use password_hash() with my php version

$hash = password_hash('xx', PASSWORD_BCRYPT, array('cost' => 10));
$username = 'xx';


$insertQuery = $db->prepare("
		INSERT INTO et_todo (username, password)
		VALUES (:username, :hash)
	");

$insertQuery->execute(array(
		'username' => $username,
		'password' => $hash
	));

also tried

$hash = password_hash('xx', PASSWORD_BCRYPT, array('cost' => 10));

$insertQuery = $db->prepare("
		INSERT INTO et_todo (username, password)
		VALUES ('xx', :hash)
	");

$insertQuery->execute(array(
		'username' => 'xx',
		'password' => $hash
	));

Hi all.

I'm just getting my feet wet with OOPHP.  My question is "why have a setter method when you can just use the __construct method to set everything?" and "would you need a separate setter method for each attribute of an object?"(i.e. set_first, set_last, set_gender, etc.)

The code...

<?php

class person{

var $first;

var $last;

var $gender;

function __construct($first,$last,$gender){

$this->first=$first;

$this->last=$last;

$this->gender=$gender;

}

function set_first($new_name){

$this->first=$new_name;

}

function get_person(){

return $this->first . $this->last . $this->gender;

}

}
?>

Hey All,

I'm tryin to make a log-in system for multiple usernames and passwords, but I don't really know how many if statements i'd need for it.. I'm also a noob..


Code: [Select]
<?php

session_start();
$users = array("user1" =>"3202", "user2" =>"2002", "user3" =>"1061", "user4"=>"1400", "user5"=>"1001");

if($_REQUEST['username'] == "infs" && $_REQUEST['password'] == "3202"){

$_SESSION['username'] = "user1" ;
$_SESSION['password'] = "3202" ;

$_SESSION['username'] = "user2" ;
$_SESSION['password'] = "2002" ;

$_SESSION['username'] = "user5" ;
$_SESSION['password'] = "1001" ;

$_SESSION['username'] = "user3" ;
$_SESSION['password'] = "1061" ;

$_SESSION['username'] = "user4" ;
$_SESSION['password'] = "1400" ;
header("Location: home.php ");
}else{


 After checking if the matching username and password exist in my array then save them in a session...


What's the best way of doing it?

Hi all

I have an SQL database with products in and I need to write the PHP script to select from the SQl based on values in the URL.

The URL looks like this:

product.php?category=32&type=90&colour=10

So I can do the script:

if (isset($_GET['category']) && isset($_GET['type']) && isset($_GET['colour'])){
$sqlCommand = "SELECT * FROM products WHERE category = '$category' AND type = '$type' AND colour = '$colour'"; }

Which works great, I have also got the other versions if the type and colour are empty.

What I can't do is get it to select all from the database where the category = 32 and the type = 90 if the URL looks like this:

product.php?category=32&type=90&colour=

In other words where the colour is set but is empty. I want the script to show all products that have the category of 32 and the type of 90 if this is the case

Please help!

Many thanks

Pete

Hi all   Is it possible to have a function with two parameters but and then check if one is passed before using it.   In this code here I want to remove spaces and change to lowercase.   If the $extra parameter is set I want to add that to the end of the string.    

function className($nametoUse, $extra){
