PHP - Basic Code Help - Variable Contents Checking

Hi Guyz,

I need to check the variable $itemDescription to see if the client has entered a '1' before the item description(example: 1 table)

Reason, is the client would like to add sales tax to all NOn-Food related items of 6.25%

This is for a local auction house. It needs to be simple. i,e. Don't wanna add any more form fields. Just let the user type the number 1 before all items that need to be taxed.

Here's my code:
Code: [Select]
<?php
ob_start();
?>
<link rel="stylesheet" href="style.css" type="text/css">
<style type="text/css">

</style>
</head>

<?PHP session_start();
ob_start();
# Config settings below
# Change these to whatever you want :)

Code: [Select]
<?php
function Login()
{
    session_start();
$_SESSION["loggedin"] = true;
echo "You are logged in!";
    header("Location: ../L_index.php"); //Aka Logged in Index.
}

function Logout()
{
$_SESSION["loggedin"] = false;
    session_destroy();
}

function checklogin()
{
    session_start();
    if ($_SESSION["loggedin"] == true)
    {
        return true;
    }
    else
    {
        return false;
    }
}
?>
This is just a tiny bit of my code, there is security holes, but as you see, there is 3 functions:
Login
Logout
Checklogin

But when i use the Login function, everything is fine, but if i then use the checklogin, then it always returns true(it returns true after i used the logout function), why?

I am attempting to us glob to display contents of a users folder using a session variable.
Example: I have a session variable called department
Code: [Select]
$row_fullname['department'];
In department I have the name of the department the user belongs to such as: office, plant, maintenance, and groundskeeping
I created a folder called docs inside of docs there are 4 subfolders called office, plant, maintenance, and groundskeeping

I found this code which will display the contents of the folder:
Code: [Select]
<?php
$files = glob( './docs/office/*.*' );

foreach ( $files as $file )
{
    echo
        '<a href="./docs/office/' . basename( $file ) . '"target="_blank">'
        . basename( $file ) . '</a><br />';
}  
?>
The above code works fine, but I would like it to only display the contents of a departments folder only if the user is part on that department.

Here is an example that I know is completely wrong but it may help explain what I am trying to do.
Code: [Select]

<?php
]<?php
$files = glob( './docs/echo $row_fullname['department'];/*.*' );

foreach ( $files as $file )
{
    echo
        '<a href="./docs/echo $row_fullname['department'];/' . basename( $file ) . '"target="_blank">'
        . basename( $file ) . '</a><br />';
}  
?>Thanks for your time

I have the following if statement:

Code: [Select]
if ((isset($select_category) == 'All') || (!isset($select_category)) && (!isset($most_liked))) {

The value for the variable gets taken from a drop down menu, which is a list of categories.

The problem I am having is with the isset condition check is that the variable is always set, but it does not consider the check for equality with the 'All' condition. Which basically means no matter which category I choose from the drop down menu, it always goes to this very first if statement, and does NOT go to the other elseif statement, and I think it has to do with the isset condition check, because without it it would work, though without it I am getting a notice warning, that the variables are undefined.

Any ideas how I can make it check if its equal to 'All' together with the isset condition check?

What I am trying to say is no matter which category is chosen, with the isset condition check, the variable is always set, thus the if statement is true, there basically seems to be a contradiction going on.

I can't figure out how I'm messing up so badly. Anyway, I have:

$con=mysqli_connect("removedforsecurity");
$finderCleanup = mysqli_query($con, "SELECT * FROM Entries ORDER BY PID DESC LIMIT 1");
$finderCleanupArray = mysqli_fetch_array($finderCleanup);
$integerCleanup = $finderCleanupArray['PID'] - 40;
$lastPID = $finderCleanupArray['PID'];
$lastPIDreduced = $finderCleanupArray['PID'] - 8;

When I var_dump $lastPID, it returns INT with a number (it works correctly.)   Then, I have this:

function getResults($con,$lastPIDreduced)

$con works correctly in the function, but $lastPIDreduced is "undefined."   What is my sin? Thanks.    

 

Still forgetting it.

Code: [Select]
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

$data = array();

class Main extends CI_Controller {

public function __construct() {
parent::__construct();

$this->load->helper('form');
$this->load->helper('html');
$this->load->helper('url');    
$this->load->library('ion_auth');
$this->load->library('session');
$this->load->library('form_validation');
$this->load->database();

//$this->load->model('prod_m');
}


function login()
{
$this->$data['header'] = $this->load->view('header', null, TRUE); 

$this->load->view('front_page', $this->data);
}

}
/* End of file main.php */
/* Location: ./application/controllers/main.php */


All I just is to make the $data array variable as public and works across all function inside the class.
Where did I made wrong?

Thanks in advance.

Hi, I wrote a simple code to check to see if the user filled in the name field, but when I uploaded the file, it just displays the code.  here 's the code.

Thanks to everyone's earlier help, I pretty much have my "Upload a Photo" module done.

However, I am wondering if the following code snippet can be streamlined?

Do I really need to check for Width and Height when above I look at if ($imageDetails = getimagesize($tempFile)){??



// ********************
// Check File-Type. *
// ********************
if (empty($errors)){
if ($imageDetails = getimagesize($tempFile)){
// Image-Array Exists.
$width = $imageDetails[0];
$height = $imageDetails[1];
$imageType = $imageDetails['mime'];

// IS IT REDUNDANT TO CHECK THE DIMENSIONS???
// ************************
// Check for Dimensions. *
// ************************
if ($width && $height){
// Width and Height Exist.
// File is Image.

// ************************
// Determine Image-Type. *
// ************************
if ($imageType !== 'image/gif' &&
$imageType !== 'image/jpeg' &&
$imageType !== 'image/png'){
// Invalid Image-Type.
$errors['upload'] = 'Image-type must be either GIF, JPG, or PNG.';
}else{
// Valid Image-Type.
// Continue Processing Upload...
}//End of DETERMINE IMAGE-TYPE
}else{
// File Not Image.
$errors['upload'] = 'Only Images can be uploaded (i.e. GIF, JPG, or PNG).';
}//End of CHECK FOR DIMENSIONS

}else{
// No Image-Array.
// File Not Image.
$errors['upload'] = 'Only Images can be uploaded (i.e. GIF, JPG, or PNG).';
}
}//End of CHECK FILE-TYPE

What do you think?

I am leaning towards taking the second check out for brevity...

I found the code below which checks to make sure something the user entered into a text field is an actual URL.  I am looking to confirm that something a user enters is an actual link to an IMAGE, so does anyone know how I could adjust this code below to do that?

Basically, this code below would accept http://monkeys.com AND http://monkeys.com/images/monkey.jpg.

I want to alter the code so that http://monkeys.com would NOT be accepted since it's not an image.  Essentially, I want to make sure whatever the user enters ends with .jpg, .gif or .png.

Anyone know how to do this?

Code: [Select]

I'm using Zebra_Form and I want to populate a select box with some values from a query.  How do I do this?  I have a returnset from MS SQL Server, but I am a newbie and I am baffled about how to frame it into the required array for Zebra_Form. 

The below example from the documentation has a hard coded set of values.  How can I replace this with my queryset ($stmt printed a little further down) instead?

Code: [Select]
// single-option select box
 $obj = &$form->add('select', 'my_select2');
 $obj->add_options(array(
     'v1' => 'Value 1',
     'v2' => 'Value 2',
     'v3' => 'Value 3'
 ));


//sql code here *
$serverName = "serverName\sqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password" );
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
     die( print_r( sqlsrv_errors(), true));
}

$sql = "select ticketID, ticketName from tickets order by price desc";
$stmt = sqlsrv_query( $conn, $sql);

for timthumb in my wordpress i use this code to
function first_image() {
  global $post, $posts;
  $first_img = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
  $first_img = $matches [1] [0];
 
  if(empty($first_img)){ //Defines a default image
    $first_img = "images/default.gif";
  }
  return $first_img;
}

it works really well, then i thought why not to make it show random images if timthumb dont find any image?

so the 1st googling i did came up with this function:
<?php 
function getRandomFromArray($ar) { 
    mt_srand( (double)microtime() * 1000000 ); 
    $num = array_rand($ar); 
    return $ar[$num]; 
} 

function getImagesFromDir($path) { 
    $images = array(); 
    if ( $img_dir = @opendir($path) ) { 
        while ( false !== ($img_file = readdir($img_dir)) ) { 
            // checks for gif, jpg, png 
            if ( preg_match("/(\.gif|\.jpg|\.png)$/", $img_file) ) { 
                $images[] = $img_file; 
            } 
        } 
        closedir($img_dir); 
    } 
    return $images; 
} 

$root = ''; 
// If images not in sub directory of current directory specify root  
//$root = $_SERVER['DOCUMENT_ROOT']; 

$path = 'images/'; 

// Obtain list of images from directory  
$imgList = getImagesFromDir($root . $path); 

$img = getRandomFromArray($imgList); 

?>

and to show random image i Place the following where i wish the random image to appear:

Code: [Select]
<img src="<?php echo $path . $img ?>" alt="" />
my question is how to place this code in my function first_image??
i need to do something like this, but it doesnt make any sense:
if(empty($first_img)){ //Defines a default image
    $first_img = " <img src="<?php echo $path . $img ?>" alt="" />
this was my thought, if i can mix those 2 normally it should work, right?

or maybe there is another way to show random image in the Code: [Select]
[i] if(empty($first_img)){ //Defines a default image[/i]
  [b]  $first_img = ?

Hi guys,

I've just started using xampp for php. My friend sent me the files i've attached below to see if apache is working for me, but i don't understand why they won't work together. Basically the .html file opens a simple login which works fine. When the password is typed in it should direct me to some links, but for some reason it doesn't. It does however look like the apache server is working fine - it could be something with the code i'm really not to sure. When i try to log in these are one set of the errors it gives me:

Warning: file_get_contents(listlinks.array) [function.file-get-contents]: failed to open stream: No such file or directory in /Applications/XAMPP/xamppfiles/htdocs/test1/userlinks.php on line 8

Warning: sqlite_close() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/test1/userlinks.php on line 61

I've literally just started learning web scripting so i apologise for over-looking anything simple.

The login.php file is also supposed to be .html aswel - i just changed it to upload.

Thanks in advance, Josh.

Hi all,
