PHP - Using Foreach To Access Data

Hello ,
I have a table like $data[$var][$i] $data is an string, $var is a string and $i is an index int.
I am tired to write for($i=1;,$i<=count($$data[$var],$i++) { echo $data['id'][$i] ... }oouuuff
How i can make it with foreach ?
I tried foreach ($data -> $field as $value) echo $value; but i doesnt work.
Any advise ?

Hello

I have included a simple login system into my website. When a user logs in, a session is started and he stays connected throughout the whole website until logging out again. The user logs in via his e-mailaddress and a password, which are stored in a mysql database.

Now I want to add a page on which a user that is logged in, can see and edit his own information (password, cellphone number, e-mail, etc.). Or easier: instead of showing "Welcome!" showing "Welcome, John!".

I thought about storing the e-mailaddress into the session, and then trying to access it to select the correct record (to edit afterwards). But so far, I haven't booked any success. I have to say that this is the first time I'm working with sessions as well, so this is very new to me.

Thank you in advance for any help!

Hi guys,

I have a for loop, that queries my database, sometimes, close to 240 times,

I want to minmise the DB access - what would be ideal is if I can query a result set, such as this..
Code: [Select]
$result = mysql_query($sql,$con);

Is it possible for me to now run a query on $result. Such as

Code: [Select]
select * from sometable where age >= '24'
So, rather than access the DB over and over again, I just query the result set, which will be much faster.

Any ideas on this one guys?

Cheers

I have this query which query the parent.name and the node.name as well.

Code: [Select]
    "SELECT parent.name
    FROM categories AS node,
    categories AS parent
    WHERE node.left_node BETWEEN parent.left_node AND parent.right_node
    AND node.name = '{$node_name}'
    ORDER BY parent.right_node AND node.left_node"
below in the foreach loop is displaying both the node and parent, I only need the parent. I have done a little if statement saying that if node.name not to display but didn't work because both parent.name and node.name are displaying the he same field name.

      Code: [Select]
<?php
foreach($iterator as $key=>$value)
        {
     if($value <> "node.name")
        
echo  $value.'<br />';

        } ?>

Now I am stumped this is far any help would be awesome

This is what I have gotten so far, this is what it does right now is display the first column of the array as a header for each foreach loop then i've got the data displayed under each header in the loop but what i am trying to understand here is i am trying to get under each header it to have 4 columns or a number of my choosing. Heres an example of what i am trying to do.

A airlie beach Andergrove Alexandra Armstrong Beach Alligator Creek B Bucasia Blacks Beach Beaconsfield Bakers Creek Balberra Bloomsbury Breadalbane Ball Bay Belmunda

Hi...

I tried to use foreach in displaying my table header, but I encountered problem when I tried to display data on the first row , my query only display the last Sum for the last Comp.

here is my code:

<html>
<head>
<title>Half Shell</title>
<link rel="stylesheet" type="text/css" href="kanban.css" />
<?php
  error_reporting(E_ALL ^ E_NOTICE);
  date_default_timezone_set("Asia/Singapore"); //set the time zone  
$con = mysql_connect('localhost', 'root','');

if (!$con) {
    echo 'failed';
    die();
}

mysql_select_db("mes", $con);


?>

<body>
<form name="param" action="" method="post" onSubmit="return false">

<div id="fieldset_PS">
<?php
   echo "<table>";
   
   $sql = "SELECT DISTINCT s.Comp FROM sales_order s, param_settings p WHERE s.Comp = p.Compounds ORDER BY s.Comp";
   $res_comp = mysql_query($sql, $con); 
   while($row_comp = mysql_fetch_assoc($res_comp)){
        $Comp[] = $row_comp['Comp'];
   }
   echo "<th>&nbsp;</th>";
   foreach($Comp AS $Comp){
    echo "<th>$Comp</th>";
  }   

   echo "<tr>
   <td>Total Kg/Compound</td>";
      $sql_sec = "SELECT SUM(TotalKg) AS TotalKg FROM sales_order  WHERE Comp = '$Comp' ORDER BY Comp";
   $res_sec = mysql_query($sql_sec, $con);
   
   while($row_sec = mysql_fetch_assoc($res_sec)){
       $TotalKg[] = $row_sec['TotalKg'];

   }
   foreach($TotalKg AS $TotalKg){
    echo "<td>$TotalKg</td>
    </tr>";
  }   

   ?>


I also attach the correct output that should be and the result from my code.

Thank you

Now I am stumped this is far any help would be awesome

This is what I have gotten so far, this is what it does right now is display each Header above each bit of data and spans across 5 columns for each foreach loop but what i am trying to understand here is i am trying to get the header then the data then another header and data and so on but only about 4 or number of my choosing grouped header/data but select how many are in each column up to 5 columns. Heres an example of what i am trying to do.

Okay,

On my original problem, I have been able to authenticate with the web service login service, and extract a cookie as follows from the web-service:

$s_Cookie = $agLoginService->agGetCookie();
$s_Cookie = AGSESSION=oxhbjcKtPw5sOymAD8m8KcKR6JL4i+TIE5mZxwOrXLwCRr8iTOvPxA==;

Now, I create data access soapclient:

$agDataService = new SoapClient($s_DataURL, $a_SoapOptions);   //yes I know I should build my own class wrapper around soapClient, but I am trying to make sure I know what to build before I do

next in the process I need to set the cookie for the data access service.

I tried using:
<b>$agDataService->__setCookie('cookie', $s_Cookie);</b>

but I don't think it's right because when I call any of the service's functions, I get no data back.

This is what their engineer had to say ( he is no help in php at all)

This is a question referring the http headers.  He needs to set the cookies as given in the examples on the wiki page.  The cookie is specified in a response http header as: Set-Cookie.  So the http headers he got back are correct.  The cookie he has to set is AGSESSION=oxhbjcKtPw5sOymAD8m8KcKR6JL4i+TIE5mZxwOrXLwCRr8iTOvPxA==;  There should be an api for setting the cookie if not there is one for setting the http header.  Set the http header name for the request (cookie - notice that is different than what you get back from an http response - read the rfc spec for http for all of the details) then set the value.  The semi colon at the end is the delimiter for http headers (in the rfc).  That is all he needs to do if he gets back some login error that means the cookies did not get set correctly.

Any ideas or help will be great. Thank you.

I'm not sure if the title explains it very well, but here is an image of it. I am trying to figure out how to access the option selected (equal, not equal, etc.), along with its input box, for each column (the checkboxes on the right) selected. The purpose of this is to allow a non-programming administrator user to create a custom query to access information. I can find out which checkboxes are selected no problem, but finding the accompanying drop-down option and input box is difficult for me. How do I do this?

If you have a suggestion on how to change it, I'm very open. Thank you in advance!

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?

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.

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.

I would appreciate any help.
Thanks.

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?
