PHP - Nested Repeat Region, Order History Page

how do i grab and print on page in date order all .jpg files in a folder ?

Hey all..

I'm trying to pick up PHP by reading ebooks and follow tutorials. I am now busy with creating a thumbnailgallery from uploaded pics per user.
I want to let the visitor scroll through a row of thumbnails by clicking next or previous.
There are 3 different rows of thumbnails.
Here's how it looks like:

<<previous (row1 of 6thumbnails) next>>

<<previous (row2 of 6thumbnails) next>>

<<previous (row3.....                  )  next>>

when page loads mysql fetches rows of information for the filenames...then there is a foreach row loop that does first a do ..while loop to build up the thumbnailrows...and then creates the navigation links previous  and next who send the "page"+1 or "page"-1 to _GET array so that the thumbnail 7 until 12 will be shown.

The problem i run into is that i want the main code page to remember at which "page" of scrolling through the thumnails he is. Now it is that when a user scrolls one row of thumbnails and stops at the 3rd "page" of it and then clicks on a different row to go to "page" 2 of that row that all the rows jump together back to "page" 1.

I thought there may be a solution in storing the number of row and the number of page into an array but can't seem to find a solution....

Has anybody got experience in this?
Help would be very welcome i'm totally stuck and cant read about it in tutorials/ebooks....

Hi everyone. I'm very new into self learning programming. Presently I'm trying to develop a simple basic Robot that would only Place a Market Order every seconds and it will cancel the Order every followed seconds. Using the following library:
https://docs.b2bx.exchange/en/_docs/api-reference.html#private-api

It would place Trade Order at a ( Price = ex.com api * Binance api Aggregate Trades Price)

I have already wrote the api to call for xe.com exchange rate with php 

<?php

$auth = base64_encode("username:password");
$context = stream_context_create([
    "http" => [
        "header" => "Authorization: Basic $auth"
    ]
]);
$homepage = file_get_contents("https://xecdapi.xe.com/v1/convert_from?to=NGN&amount=1.195", false, $context );
$json = json_decode($homepage, TRUE);
foreach ($json as $k=>$to){
    echo $k; // etc
};


?>

And also for the Binance Aggregate Price in JavaScript

 

<script>
var burl = "https://api3.binance.com";

var query = '/api/v3/aggTrades'; 

query += '?symbol=BTCUSDT';

var url = burl + query;

var ourRequest = new XMLHttpRequest();

ourRequest.open('GET',url,true);
ourRequest.onload = function(){
    console.log(ourRequest.responseText);
}
ourRequest.send();
</script>

  My problem  is how to handle these two api responds  and also the functions to use them to place a trade and cancel it.
Please help me out. Thanks in advance on any help.

I am using Dreamweaver CS4 to build a website. On my contact page, I made a form with spry validation. I used a tutvid tutorial to learn a simple form handler script (I'm a complete newb at PHP) and everything works great. The only problem I'm having is, in my Dreamweaver template, I have an editable region that has the form. When  the user clicks to submit the form, a new html page opens up that looks nothing like my website.
What I'm trying to accomplish is having the form disappear and be replaced in the same editable region with my "thank you" message. This way, the user just submits, the form disappears, and they get a thank you message on the same page, in the same place where the form was.

Here is the form code:

Code: [Select]
<form id="frmContact" name="frmContact" method="post" action="contact_form.php">
     <fieldset><legend>Submit a question or comment...</legend>
     
       <p>
         <label for="name">Name:</label>
         <span id="spryName">
         <input type="text" name="name" id="name" />
         <span class="textfieldRequiredMsg">Name is required.</span><span class="textfieldMinCharsMsg">Must have at least 3 characters.</span><span class="textfieldMaxCharsMsg">Must not exceed 20 characters.</span></span></p>
       <p>
         <label for="email">Email:</label>
         <span id="spryPassword">
         <input type="text" name="email" id="email" tabindex="10" />
         <span class="textfieldRequiredMsg">Email address is required.</span><span class="textfieldInvalidFormatMsg">Not a valid email address.</span><span class="textfieldMinCharsMsg">Not a valid email address.</span><span class="textfieldMaxCharsMsg">Not a valid email address.</span></span></p>
       <p>
         <label id="message" for="question">Please tell us how we can help you:</label><br />
         <span id="spryText">
         <textarea name="question" id="question" cols="45" rows="5" tabindex="20"></textarea><br />
         <span class="textareaRequiredMsg">A question or comment is required.</span><span class="textareaMinCharsMsg">Must have 16 characters minimum</span><span class="textareaMaxCharsMsg">Must not exceed 500 characters.</span></span></p>
       <p>
         <input type="submit" name="submit" id="submit" value="Submit" tabindex="30" />
       </p>
     </fieldset>
     </form>

Here is the PHP script:

<?php

/* Subject and Email variables */

$emailSubject = 'Contact Form Response';
$webMaster = 'centerline.computers@gmail.com';

/* Gather Data variables */

$nameField = $_POST['name'];
$emailField = $_POST['email'];
$questionField = $_POST['question'];

$body = <<<EOD
<br><hr><br>

EOD;

$headers = "From: $emailField\r\n";
$headers .= "Content-type: text/html\r\n";
$success = mail($webMaster, $emailSubject, $body, $headers);


/* Results rendered as HTML */


$theResults = <<<EOD

<h2>Thank you for submitting.</h2>
<p>We will get back to you as soon as possible.</p>

</body>
</html>
EOD;
echo "$theResults";

?>

Thanks for any help you might have for me!

Hi,   In reference to my first attached image, I have a form which displays two SELECT/drop-down fields (labeled "Store Name" and "Item Description".....and both of which pull-in values from two separate lookup/master tables, in addition to providing an additional option each for "NEW STORE" and "NEW ITEM").   Now, when first-run, and/or if "NEW STORE" and "NEW ITEM" are not selected from the drop-down's then the two fields in green ("New Store Name" and "New Item Name" are hidden, by means of the following code:  

<div class="new-store-container" id="new-store-container" name="new-store-container" style="display:none;">
    <div class="control-group">
        <div class="other-store" id="new_store_name">
            <?php echo standardInputField('New Store Name', 'new_store_name', '', $errors); ?>
        </div>
    </div>
</div>

  Conversely, if "NEW STORE" and/or "NEW ITEM" are selected from the two drop-down's then one (or both) of the "New Name" fields are unhidden by means of the following two pieces of code, one PHP and the second JS:    

<select class="store-name" name="store_id" id="store_id" onclick="toggle_visibility('store_id','new-store-container')">
    <?php echo $store_options; ?>
                            
    <?php
        if($values['store_id'] == "OTH")
            {
                echo "<option value='OTH' selected> <<<--- NEW STORE --->>> </option>";
            }
        else
            {
                echo '<OPTION VALUE="OTH"> <<<--- NEW STORE --->>> </OPTION>';
            }
    ?>
</select>

 

function toggle_visibility(fieldName, containerName)
{
    var e = document.getElementById(fieldName);
    var g = document.getElementById(containerName);
            
    if (e.value == 'OTH')
        {
            if(g.style.display == 'none')
                g.style.display = 'block';
            else
                g.style.display = 'none';
        }
}

  All  of that is working just fine. The problem I'm having is that when I click the "Create" button, after having left any one of the form fields blank, the two "New Name" fields are hidden again, which I don't want to happen i.e. I want them to remain visible (since the values of "store_id" and/or "item_id" are "OTH"), so that the user can enter values into one or both of them, without havng to click on the drop-down a second time in order to execute the "on-click" code.   The second attached image shows how the fields are hidden, after clicking "Create".   How can I achieve that? It would be greate if someone could cobble-up the required code and provide it to me, since I'm relatively new to this.   Thanks much.    Snap1.png   26.14KB   0 downloads    Snap2.png   149.47KB   0 downloads      

Hi! Having a lot of fun dusting off the coding and putting together a site with PHP, CSS, and jQuery. I've run into one problem that I can't get past though. I implemented jQuery History to use hashtags to maintain browser back/forward buttons and linkability of the site (and not reload header and footer when updating content). The main purpose of the site is to showcase photography that's hosted on Flickr. I've got this working well using Slickr.

I have the Slickr code to load my galleries sets in a file called 'pictures.php' which is loaded fine into #page_content using a link to #pictures. The problem arises when I click on a gallery/set: I get taken back to the default view of the site without any hashtage because Slickr requires a link using parameters, so:

www.myexamplesite.com/#pictures

becomes

www.myexamplesite.com/index.php?id=72157626067797650&p=1

As you can see, since it loses the hashtag, I am no longer looking at the right page. Does anybody have any ideas on how I can specify both the hashtag and the parameter? Cheers!

I have the below code to open contents in a div or modal window and at the same time showing the url that matches the specified page which works as expected, no problems rising:

$(document).ready(function(){

///////LINK in a Div////////

 $('#all').delegate('a.img-lnk, a.txt-lnk', 'click', function(){
  $('#main').empty();
  var page = $(this).attr('id');
  var pageurl = $(this).attr('data-seo');
  $('#main').load("../"+ page + ".php");
  window.history.pushState('','',pageurl);
 });

///////LINK in a Modal Window////////

 $('#all').delegate('a.pop-lnk', 'click', function(){
  var poppage = $(this).attr('id');
  var popurl = $(this).attr('data-seo');
  $('#popup').load("../char-inf/"+ poppage + ".php");
  window.history.pushState('','',"/char-inf/"+ popurl);
 });

 $('body').delegate('.hide-it', 'click', function(){
  $('.hide-it').hide();
  $('#popup').empty();
  window.history.back();
 });

});

Problem: If I give you a url of a link in my page e.g. www.example.com/test1 and paste it in your browser the test1 page will open normally,   BUT after that if you navigate to page test2 then the new url becomes www.example.com/test1/test2.   Is there a way to turn the url at its normal state which would be www.example.com/test2?

hello guys, this is my first post on this forum and I really need your help on this.

What I have is: I created a login page a home page and a index page.

The index page checks if the session is set. If it's not the login page will be shown. If it is the homepage will be shown.
Whenever the user logs in, the session gets set. The problem is is that whenever I login and the user presses the back button on his browser my session will always be returned false which means that whenever a user has logged in, the index page doesn't show home but shows the login page again even though the user has already logged in.

Here is my code to make you understand a little bit better:

session.php:
Code: [Select]
<?php
    class Session
    {
         function __construct()
         {
             
         }
         function set($name, $value)
         {
             $_SESSION[$name] = $value;
         }
         
         function get($name)
         {
             return $_SESSION[$name];
         }
    
         function stopSession()
         {
             unset($_SESSION);
             session_destroy();
         }
         
         function startSession()
         {
             if(!isset($_SESSION))
             {
                session_start();
             }  
         }
         
         function check_session()
         {
             if(isset($_SESSION['username']) && !empty($_SESSION['username'])) 
             { 
                return true;
             }
             else
             {
                return false;
             }         
        }
    }
?>

login.php:
Code: [Select]
<?php
  class Handler_Login extends Action_Handler
  {
      function __construct($action_handle)
      {
        parent::construct($action_handle);
        $this->action = $action_handle;
      }
       function secured_handler()
       {
           $password = $_POST['password'];
           $username = $_POST['username'];
           $login = $this->dbh->Login($username, $password);
           if ($login == true)
           {
               $this->session->startSession();
               $this->session->set('username', $username);
               $this->view->displayHome();
               $this->view->display(); 
           }
           else
           {
               //This is going to get more advanced later on, I'm currently working on resolving my session issue before I continue on this.
               echo "you are not logged in";
           }
       }
  }
?>
index.php:
Code: [Select]
<?php
  class Handler_home extends Action_Handler
  {
        public function __construct($action_handle)
       {
           parent::construct($action_handle);
           $this->action = $action_handle;
       }
       function secured_handler()
       {
          // for some reason this always returns false when the user goes back in history :(      
          if ($this->session->check_session() == false)
          {
              $this->view->displayLogin();
              $this->view->display();
          }
          else
          {
              $this->view->displayHome();
              $this->view->display();
          }
       }
  }
?>

anyone has an idea why the login page is always shown ?

Is there a way to change the url in the code below using window.history.pushState dynamically to match the "page" variable?

$(document).ready(function(){

$('#all').delegate('a.pop-lnk', 'click', function(){
  var page = $(this).attr('id');
  $('#popup').load("../folder/"+ page + ".php");

window.history.pushState('','','/page');
});
});

A friend of mine is looking at relaunching a site he used to run and I am going to try to persuade him to move over to a dynamic site.

The site is a Football Clubs history site and contains around 2,000 games and several hundred players. The obvious advantage of a dynamic site is that even the bits I just mentioned run to around 2,500 static pages, which could be reduced to just 2 pages if dynamically driven.

I am fairly confident that I can do the conversion, but there is one thing that I already know I may struggle with and that is the page which shows game, births and deaths on this day in history. A rough example (using a very heavy Javascript code) can be found at http://follyball.co.uk/jeff/.

In a simplified form (ignoring for now the foreign keys to relationships that these tables actually have) there will be two tables
GAMES
game_id | date | competition | opponent | score | attendance

PLAYERS
player_id | surname | firstname | date of birth | date of death

What I would be looking for is a way to take todays date, and find any corresponding records in games.date, players.date of birth, players.date of death on the same date in previous years. This would be simple to do as three different queries but as I would like to actually mix the three and show them in date order, I would like to do it in one query, presumably using UNIONS.

On top of this, I would also like a slightly different output for each different set, for example, if it was a game I would like
year, competition, opponent, score, attendance,

Whereas if it is a players birth or death, I would like it to show something like
firstname surname was born in year

Before I go delving too deep into how it may be done, I would like to know if it can be done! I cannot see why it would not be able to generate this but if it is going to be way out of my ability, then I will look for another option!

Thanks in advance

Dear fourm, i am wondering if anyone can shed some light on this form submission problem with back/forward buttons.

long story short: i used to make a form, then submit to a form process php file. errors were difficult to deal with. Thus, many people tell me to submit to the same page. I now submit to the same page.

my homepage has a login button. i use a csrf token in a hidden input matched with a session variable. i decided to submit to same page and handle the submit like so:

if server request-method = post and isset input name and isset session token then check the token with hash_equals

if everything matches then show the login page.

i don't have a problem with the form and the form submission processing. everything i fine.

now when i use the browser refresh button on the login page, i am sent back to the homepage. all is good.

when i press the back button, i go back to the homepage again. super.

then i press the forward button in the browser and i get a not connected error.

the back button now also shows this error.

i tinkered around a bit and added crazy ideas and it worked one time with unset($_POST) as an else to the if mentioned above.

the idea is that if server request-method is post without an else. the page is listed below for any get request to process.

i assume that the browser is trying to repost data is empty but my if statement should kick it out to the get code, right?

what i want is to unset the csrf token and the matching session token for security purposes. i suppose that this breaks the back/forward buttons?

how can i get the browser to show the homepage regardless of the post situation? there must be a logical answer. something in my code is breaking this an preventing the browser from simply loading the home page

any help is greatly appreciated! Thank you.

Hello everyone,
I am having a problem since some time now and need some help.
I have created a login page where the user has to input a username and password to login.
The username will be put in a session and when the user logs out the session data and session itself gets destroyed.
However when I go back in the browser history to the page where I logged in I get the "famous" resend information dialog that asks you to resend the information from the login form. Which means that all the post data gets resend and the user logs in again without having to put in a username and password.

Here is my code:

using a header to redirect to the login page is not going to work since I use my view_manager to display the pages.
Does anyone know of any solution to get rid of that stupid resend information dialog without using a header? I tryed unsetting the values of POST in my login code but that did not seem to work. Please help me out I've been looking for an answer for over 1 and a half week so far

Is there anyone who knows how to remove the POST data from a form when the user goes back in browser history?
If it's not possible, is there any solution except using a header?

Like many parents, I'm challenged with keeping my kids from browsing the evil parts of the internet. My son is 11 and my wife caught him deleting IE history the other day. The computer he uses is a Windows 8.1 laptop, and it is not Pro. How can i let him use internet explorer on his own user but keep him from tampering with any of the history ( or settings for that matter)?

Is there a better solution? I found some internet history logging software online, but I didn't feel comfortable with the source, and fear it may contain viruses or other malware.
