PHP - Php Talk To Hosted Ms Access File?

I've got a question, I thought I'd be able to do this fairly easily. I don't want to do an .htaccess solution also.

I tried this,

define('ACCESS', TRUE);


// then on other page 
 if(!defined('ACCESS'){die('Direct access not allowed.');}


Need some assistance, appreciated.

I have a weird kind of problem.
I uploaded all upload-directories through FTP which have 777 permissions and owner name 'abc'
This means I can access all of them through the codes.
But while creating files inside those full permitted directories, the compiler complains for access denied.
Meanwhile, a different directory is created with same name whose owner is 'apache' itself and the previous directory is lost.
Then I cannot change the permissions of that directory through FTP.
I don't if it is apache server's problem itself or not.
Or is it a way to define user while creating/editing/deleting files and directories through php code itself?

A shipping vendor (like Stamps.Com) provides me a Printable Shipping Label to display on my website for Visitors to print.

When Visitors come to my page, my PHP code:
1.) connects to Shipping Vendor via an API,
2.) downloads and converts the base64 data to image
3.) names the image to Customer Order Number.png
4.) saves image in directory
5.) then displays image to Visitor.

$Shipping_Label_Data = $LabelVendor->data[0]->contents; // vendor's API
file_put_contents('Label-Directory/'.$Order_Number.'.png',base64_decode($Shipping_Label_Data));

echo '<img src="/Label-Directory/'.$Order_Number.'.png" />';

Later I realized the security flaw: any snooper can fish for other Visitor's labels in my Label directory.

What is the best way to prevent the display of other people's labels?

Thank you!!

I have solved this now.

Hi!

I am trying to use the View Model Design Pattern in my application

The problem is that it is the first time I use it and I am a beginner.

So, I have the logic in the Model and the "front end" in View. I am talking about a sign up page.

In the current Html file I am trying to access an error array from the model file and display it to the user above the input field.

 

Here is the a snippet from the Model (Signup.php)

$account = new Account($con); //the account which takes as param the db connection
$error = null; //the array

// anything the user writes gets inside this array
if (isset($_POST["submitButton"])) {

 $firstName = UnifyFormInput::unifyUserFLName($_POST["firstName"]);
 $lastName = UnifyFormInput::unifyUserFLName($_POST["lastName"]);
 $username = UnifyFormInput::unifyFormUserName($_POST["username"]);
 $email = UnifyFormInput::unifyFormEmail($_POST["email"]);
 $password = UnifyFormInput::unifyFormPassword($_POST["password"]);

 //contain true or false based on the query being successful or not
 $success = $account->register($firstName, $lastName, $username, $email, $password);
 if ($success) {
  $_SESSION["userLoggedIn"] = $username;
     header("Location:index.php");
 }else{
    $error = $account->getError(Constants::$registerFailed);

 }
}
//compact — creates array containing variables and their values
//call render function from View file to show the register page content
View::render('register', compact('error'));

And here is the view:

 <?php                 
        if (!empty($error)) {
          echo  $account->getError(Constants::$loginFailed);
       }                        
?>
<input type="text" class="form-control" name="firstName" placeholder= "First Name" value="<?php getInputValue("firstName"); ?>" required>

 

Hello first time poster here .

Soni have been in the proccess of designing a website that would give images to users . But only owner of an image will get thier own image .

And some people may not access thier image whom are invalid untill i make them valid users.

Si.my problem is i want to stop people from accessing these images by typing thier mysite.com/path and these files only be accessable via a php that is in my website .

How do i go about doing that .

Is it iam my new to this or there is not a convenient way to do this .

Thanks in advance

I use jQuery when adding messages. However, the file can be called directly. For example: includes/add_comment.php?id=2

So, I can make a form and call this file directly to add a message. ID is user id and form can be submited with HTML form wherever are located.

How to prevent direct access to the file when called through a Ajax?

please it is very important!!
I have a script (main file is index.php) that is called into an iframe src via an url reference... http://www.xxxx.com/folder/userfolder/folderwithemailname/index.php
works perfectly!!..

How can i prevent someone getting direct url access to the file?
if someone were to take the url:    http://www.xxxx.com/folder/userfolder/folderwithemailname/index.php and place it into the address bar, they have access to the file...

points to note:
-i have no database for this script,
-the iframe is called directly into a html file,
- i dont know the userfolder or the emailfolder names,
- and the index.php is linked to several other .php and .js and .html files in different folders.... // i can add something like this to these file:(i found this on the net).
Add this to the page that you want to only be included

<?php
if(!defined('MyConst'){die('Direct access not premitted');}
?>

then on the pages that include it add

<?php
define('MyConst', TRUE);
?>

this will prevent the files being accessed, but then i cant access the file via the iframe url..

please any ideas???
best regards

Hi, I am integrating Paypal Pro into my checkout and struggling to get it to work correctly.   I am using this code to connect to paypal - which all works correctly, processes payments as it should and send paypal receipts to the customer and to me.   The problem is that when Paypal redirects back to my receipt page, it is not triggering the email (customer_mail_new.php and client_mail_new.php) to tell me what exactly they customer has ordered!   I've been staring at this code for hours now and wonder if anyone can see anything obvious that I have (or haven't) done that is causing the emails to not send at the end of the receipt page?   (paypal.php)

<?php 

  

initially i used this code on xampp and it worked just fine.
now when i have used a free web hosting site (000webhost.com) created the same database there the followin error occurs:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/a3907930/public_html/checklogin.php on line 18

Wrong Username or Password


following is the code for my check login page: (with $username="root" and $password= "" this worked fine in xampp)
 the username and password in the below code was generated when the database was created in www.000webhost.com

Code: [Select]
<?php
$host="xxxxxx"; // Host name 
$username="xxxxxx"; // Mysql username 
$password="xxxxxx"; // Mysql password 
$db_name="xxxxxx"; // Database name 
$tbl_name="xxxxxx"; // Table name

// Connect to server and select databse.
mysql_connect($host, $username, $password)or die("cannot connect"); 
mysql_select_db($db_name)or die("cannot select DB");

// username and password sent from form 
$myusername=$_POST['myusername']; 
$mypassword=$_POST['mypassword'];
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
  session_register("myusername");
  session_register("mypassword"); 
  header("location:login_success.php");
  }
  else {
   echo "Wrong Username or Password";
   }
?>

MOD EDIT: code tags added, DB credentials removed.

if(isset($_POST['clearflags'])){ 
   $output = shell_exec('php clearflags.php'); 
}

The above works fine on my local development server running Debian 10, PHP 7.4 and Apache 2.4.25. clearflags.php is a script that clears various fields in a MySQL database so it's easy to determine if it properly ran or not.

On my hosted server however (Bluehost), clearflags.php is never executed. My hosting service swears that SAFE MODE is not on in PHP (which is also Version 7.4). If I call from the command line (php clearflags.php), it runs fine.

$output on the hosted server is "Content-type: text/html; charset=UTF-8 " but nothing on my local server where the script is called and runs OK. No entry appears in the error log about this

I've also tried using exec() with the same failed result

Running phpinfo() on the hosted server shows that disabled_functions are "no value"

Thoughts?

I run a dev site locally on Windows and the real site on a hosting provider on LINUX. PHP5, XAMP, etc.

Locally my fopen works.
On the web server it throws an error: "Warning: fopen() [function.fopen]: Unable to access" filepath/name

The file exists on both servers; upper/lower case is correct; so are access rights.

I noticed the error only today; this was working for the last 7 months; the function serves a range of content-types; just tested XLS and it works.

Now I am stuck 

This line throws the error:
$handle = fopen($strPathFileName, 'rb');

$strPathFileName uses / only

Any pointers appreciated... thanks.

When I send values to the foreach they are not recorded in the array.

$x = $getProductID;
$_SESSION['pColors'] = array();

if(isset($_POST['pColors'])) {

    foreach($_POST['pColors'] as $colorKey => $RColors) {
        $_SESSION['pColors'][$colorKey] = $RColors;
    }
}

var_dump($_SESSION['pColors']);

Send date with AJAX:

                $('.addToCart').click(function(){
                    $.ajax({
                        url:""+realLink+"cart.php",
                        method:"POST",
                        data:{action:action,pColors:pColors},
                            success:function(data){
                               //alert(data);
                            }
                    });
                });

Hey Guys.   I have a class named CoreCartFunctions. In the class there is a protected property named $menu_item_id which is initialized  as null.   A method named GetMenuItemId assigns the $menu_item_id its value. I have tested it out using the following,  to see if a value got returned and it did

fb($menu_item_id->GetMenuItemId(), "This is the menu id");

The problem is when I access the property from a different public method in the same class it dones't return anything.

fb($menu_item_id->DisplayMenuItems());

It only returns something when I hard code a value to it.... Not sure why this is happening. Here is my full code.   Please not the example below may have some syntax errors since I just copied and paste pieces of my code, to show a quick and dirty example.

class CoreCartFunctions {


protected $menu_item_id = NULL; 


public static $items; //Equal to the a long session string

protected function GetMenuItemId() {


      foreach (self::$items as $menu_item_id_session) {


/***********************************
Get the id of the menu item item
************************************/
$this->menu_item_id = preg_match_all('/\-(.*?)\*/',$menu_item_id_session,$match_found)?$match_found[1][0]:"";
// The following line shows example of above line
// $menu_item_id = "12";

public function DisplayMenuItems(){
  

return $this->menu_item_id; // Doesn't return Item ID

}




}
