PHP - Limited Guest Access - Help

I'm currently learning PHP and I think I have a decent grasp of procedural programming so I'm trying to set it up a little bit and get a hang of OOP. I'm finding it a little tough going but I am making progress, the syntax and coding of it is fine but I don't quite get some theory and the best way to use it yet. It's only my third day in but I have a question relating to access modifiers.

It's a simple one, but what is the point?

That may sound a bit narky but I keep hearing and reading that it's good programming convention but it's never really explained why. What am I missing?

I get how they work but I don't really get why to use them. I've even read that private should only be rarely used, if at all as it makes testing harder and it stops you from being able to extend your classes. I'm not against using them - I want to learn to program to the very best of my ability but I'm eager to learn what benefits it actually has. Is there a technical reason, for example?

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

}




}

I've got data in a mySql database which is updated daily. I would like to allow webmasters to place this data in a form of a widget on their websites provided they pay for access. If not payment comes through we should be able to block access.   Any suggestions how this project would be designed?

Hi I'm after a solution to a problem I have. I'm building a small site for charity which the the client wants to email(with a url link) to say 1000 selected companies but only wants them to be able to view the site and register interest and not anyone else or if they forward the mail to a non prefered client? Any help to point me in the right direction would be good thank-you.

Hi, i am learning WordPress and have just started, but i have a problem....when i try to access my site i get this:

Warning: Cannot modify header information - headers already sent by (output started at /home/smra9/public_html/wp-content/themes/evanescence/functions.php:6) in /home/smra9/public_html/wp-includes/pluggable.php on line 890

when i open pluggable.php and i go to the line 890 it says:

header("Location: $location", true, $status);


i will also copy a text from line 885 to 890 so maybe you will understand better:

if ( $is_IIS ) {
header("Refresh: 0;url=$location");
} else {
if ( php_sapi_name() != 'cgi-fcgi' )
status_header($status); // This causes problems on IIS and some FastCGI setups
header("Location: $location", true, $status);
}


Can anyone help me, i don't know what to do

Hello, folks.
I am having a little trouble with this script. I want it to be able to read a directory, not just a file, and list all files in the directory along with their id3 tags. I can't get it to read all the files, it reads only the first file in the directory.
Here, I'm posting the basic (stripped down) script, without mods or add-ons.
I would appreciate any help.
Thanks.

Code: [Select]
<?php
    require('error.inc.php');
    require('id3.class.php');
    $nome_arq  = 'music.mp3';
 $myId3 = new ID3($nome_arq);
 if ($myId3->getInfo()){
         echo('<HTML>');
         echo('<a href= "'.$nome_arq.'">Click to play: </a><br>');
         echo('<table border=1>
               <tr>
                  <td><strong>Artist</strong></td>
                  <td><strong>Title</strong></font></div></td>
                  <td><strong>Track</strong></font></div></td>
                  <td><strong>Album/Year</strong></font></div></td>
                  <td><strong>Genre</strong></font></div></td>
                  <td><strong>Comments</strong></font></div></td>
               </tr>
               <tr>
                  <td>'. $myId3->getArtist() . '&nbsp</td>
                  <td>'. $myId3->getTitle()  . '&nbsp</td>
                  <td>'. $myId3->getTrack()  . '&nbsp</td>
                  <td>'. $myId3->getAlbum()  . '/'.$myId3->getYear().'&nbsp</td>
                  <td>'. $myId3->getGender() . '&nbsp</td>
                  <td>'. $myId3->tags['COMM']. '&nbsp</td>
               </tr>
            </table>');
         echo('</HTML>');
    }else{
     echo($errors[$myId3->last_error_num]);
   }
?>

If a client connects to a ReactPHP TLS socket server, is it possible to obtain the symmetric key from within the PHP code?  Hoping it will allow me to decrypt  analysis traffic between two using Wireshark.

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);
                            }
                    });
                });

Hi guys,

I am making a site where users upload files (like images, pdfs, etc) to the server.

My question is, how does Facebook handle file permissions, restricting access to files uploaded to their servers based on what a user sets?
Because I need to implement a similar thing and have no idea how to do it in a clean way.

I have had two thoughts on storing the files 1) in a DB or 2) in a folder out of the wwwroot, which would prevent access by anyone without knowing the path (or some such) but it is the more "real" permissions implementation I am stuck on.

I obviously would like to achieve this with PHP and MySQL(i).

Any help is much appreciated.

Cheers in advance.

I am trying in vain to access the numbers in the "sims" array using the code below, I have tried various numbers of nested foreach loops but get errors every time, can anyone help point me in the correct direction please.   Thanks   Gordon

$stock = (array(1) 
	{ ["stock"]=> array(2) 
		{ [0]=> array(2) 
			{ ["operator"]=> string(3) "ECL" 
				["sims"]=> array(51) 
					{ 
					[0]=> int(8944122650438410000) 
					[1]=> int(8944122650438409000) 
					[2]=> int(8944122650438409000)
		 			} 
		 	} 
		[1]=> array(2) { 
			["operator"]=> string(2) "JT" 
				["sims"]=> NULL 
} } } )


foreach ($stock as $key1 => $item1)
            { 
                foreach($item1 as $key2 => $item2)
                { 
                		foreach($item2 as $key => $value)
                		{
                    		echo $value[sims] . "</br>";
                		}
            	}
			}

I am looking to save the user's access of an application.  For instance, when they log in, I create a record in the "track_login" table which includes information such as the requesting IP, the user's ID, the date, (not the user's password), etc.  And then for every page they visit, I store a record in the "track_page_viewed" table which includes a FK to the "track_login" table and also includes additional information about their request.   Both the track_login and track_page_viewed tables are currently in the same database as used by the primary application.   So far, so good.   Next, I want to start tracking when a user does special tasks such as when they forget their password and request that a new one be emailed to them. Or maybe when they attempt to login with an invalid username and password.  Currently, I just included another table called "track_special" which includes the data, the type of special request, etc.   Now, I am thinking of adding three other things to track: General PHP errors MySQL errors Try/Catch errors which I did not expect to happen One option is just to add these to my "track_special" table or maybe make one or three new tables in the same database.   But is this a good idea?  If I have a SQL error, do I really want to store the error in the same database?  Maybe I should use a separate database called "myTrackerDB", and include all the above tables in that database?  Or maybe I should just write the data to a flat file, and parse the file on a regular basis, and then store the information in the database?   Please provide any recommendations, guidance, suggestions, criticism, etc.  Thank you

How does a web server, with a database connect to the emails it receives?

How does the web server get the contents of the emails it receives so I can parse it?

Thanks

Im developing a registration script and using godaddy as my host. Im getting "Access denied for user 'headstyle1'@'%' to database 'users'" when running the registration script. Is there some kind of permission I have to set?

I am trying to make an edit page to edit any of my post...so i designed a manage post page manage-posts.php with the given code:

Code: [Select]
    <?php 
echo '<form name="frmMain" action="del1.php" method="post" OnSubmit="return onDelete();">';
$objConnect = mysql_connect("hostname","username","password") or die(mysql_error());  
    $objDB = mysql_select_db("dbname");
    $strSQL = "SELECT * FROM text";  
    $objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");  
     
echo '<table width="600" border="1">';  
    echo '<tr>';  
   echo '<th width="91"> <div align="center">ID</div></th>'; 
echo '<th width="91"> <div align="center">Date</div></th>';  
    echo '<th width="91"> <div align="center">Title</div></th>';
echo '<th width="91"> <div align="center">Author</div></th>';
    echo '<th width="30"> <div align="center">Edit</div></th>';
echo '<th width="30"> <div align="center">Select</div></th>';
    echo '</tr>'; 
    while($objResult = mysql_fetch_array($objQuery))  
     {  
       ?>
    <tr> 
    <td><?=$objResult["id"];?></td>
    <td><?=$objResult["date"];?></td> 
    <td><?=$objResult["title"];?></td> 
    <td><div align="center"><?=$objResult["author"];?></div></td> 
<td align="center"><a href="edit.php?NewsID=<?php echo $objResult["id"];?>" name="edit">Edit</a></td>   
    <td align="center"><input type="checkbox" name="chkDel[]" value="<?=$objResult["id"];?>"></td> 
    <input type="hidden" name="id" value="<?=$objResult["id"];?>" />
    </tr> 
     <?
      } 
   
    echo '</table>';
echo '<input type="submit" name="btnDelete" value="Delete">'; 
    echo '</form>';

and i designed another page edit.php to perform deletion of that particular post with the following code "
Code: [Select]
<?php 
 
$objConnect = mysql_connect("hostname","username","pass") or die(mysql_error());  
    $objDB = mysql_select_db("dbname");
  
   $strSQL = "SELECT * FROM text";  
    $objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");  
$objResult = mysql_fetch_array($objQuery);
?>
  <input type="hidden" name="id" value="<?=$objResult["id"];?>" />
  Title : <br /><input type="text" name="title" size="100"  maxlength="100" value="<?=$objResult["title"];?>"/> <br />
            Date : <br /><input type="text" name="date" size="20"  maxlength="12" id="TextBox" value="<?=$objResult["date"];?>"/> <br />
            Author : <br /><input type="text" name="author" size="20"  maxlength="100" value="<?=$objResult["author"];?>"/> <br />
            <br />
<input type="submit" value="Submit" name="submit" />
            </p>

</form></fieldset></div>
