Hi guys

Just wanted to knw whats the php logic needed to create this function which shows current users viewing a topic

I knw we can have a database table which stores the topic ID as well as user id and that way we can record who is viewing a topic but what happens when they leave?

some users can just close there browser in which case I would never know when they left?


thank you guys

Hi there

I have a MySQL database table that has multiple records which look like (1, Which of these are your favorite color(s)?, Red||Blue||Orange||Green, question-type1 )

I have written some PHP code in extracting that data into a HTML form. (The above data looks like a question with multiple options (radio buttons/checkboxes) below it).

Below is what I'm trying to achieve:
 When the action is Submit: store the question number, user responses of the options , time stamp and user name into a new database table.

I came to know that passing arrays will do the job, but I got stuck in the middle.

Please see the attached documents that has the code.

TIA

hmm im having some trouble tackling this problem

i have a database table with topicname then 3 columns with 3 pdfs in each one
all the files are stored in a directory called topicfiles in the server
so like 3 topicnames with 3 files in each one

with this page i want to make
i want to display each topic name with the files under it calling it from the server
like

Code: [Select]
topic 1
    file1.pdf
    file2.pdf
    file3.pdf

topic 2
    file4.pdf
    file5.pdf
    file6.pdf

topic 3
    file71.pdf
    file8.pdf
    file9.pdf


i tried using dhandler to access all files in the folder and only managed to display all of the files in rows using foreach loop
was thinkin of using mysql query to access the topic name and then each file for that topic but not sure hmmm

       $this->curl_init = curl_init(); 
    }

    public function debug(){
 
       curl_setopt($this->curl_init, CURLOPT_VERBOSE, TRUE);
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp);

    }

    public function setUrl($url = null){
       $this->CURLOPT_URL = $url;
       curl_setopt($this->curl_init, CURLOPT_URL, $this->CURLOPT_URL);
    }

    public function execute(){

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }
}

$curl2 = new curl2;
$curl2->connect();
$curl2->setUrl("http://www.linuxformat.co.uk");
$curl2->debug();
echo $curl2->execute();



It display a blank page like attachment result1.jpg, but if I move the
$fp = fopen("curl2.txt", "w"); 
curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);
from function debug() and join it with function execute()
like this:
  public function execute(){
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }

it return me Linuxformat content ( expected result ) like result2.jpg

below is the working code :
class curl2{

    private $curl_init; 
    private $CURLOPT_URL;

    public function connect(){ 
       $this->curl_init = curl_init(); 
    }

    public function debug(){
 
       curl_setopt($this->curl_init, CURLOPT_VERBOSE, TRUE);
      

    }

    public function setUrl($url = null){
       $this->CURLOPT_URL = $url;
       curl_setopt($this->curl_init, CURLOPT_URL, $this->CURLOPT_URL);
    }

    public function execute(){
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }
}

$curl2 = new curl2;
$curl2->connect();
$curl2->setUrl("http://www.linuxformat.co.uk");
$curl2->debug();
echo $curl2->execute();

 
Why I couldn't split "CURLOPT_STDERR, CURLOPT_RETURNTRANSFER" with "curl_exec"

I'm trying to either update my database if some data matches the if statement, or insert the data in a new row if it doesn't match (if possible).
The code will update the database just fine if the data matches, but if not, it won't insert the new data. (When I leave off the if statement it will insert just fine). I fear I'm not using the if...else correctly.

Thanks for any help.

Hi

I have plans in developing a connect function for remote login to my web side. I can't find any useful on Google.

Some idees on how to code a API connect button? Something similiar to Facebook connect, Twitter connect etc. BUT this should not rely on facebook api. I'm going to make my own stand alone api.

I know I need to use REST in backend, but I'm missing the knowledge to know how to send / recive the login data, and how to know when a user are online or not.

I'm greatfull for any help. Also links.

And also tips on how to make a developer plattform for apps, much like the way Facebook have it.

Hello,

Alright I am having a few issues here. Let me explain what I am doing...this is a script that allows a customer to split an order..he can split certain items out of one order and it will create another order with the items he split added to this order, and then subtracting the items from the old order. The products are stored in one field called products, they are stored in a delimited list like this qty, product name, price each, product id | qty, product name, price each, product id |etc.

Now, before you say why are you storing your products like that?? The reason I have to store my products like so is because the customer does not want the products stored in the order table to be dependent off the products table like they were before. In that case if he modified a product it would modify all of the orders with that product stored in them. Make sense? I am aware a delimited list probably wasn't the best way to do this but it was the best way I could think of.

Ok here is my list of issues.
  1) Everytime you split an order, it is not creating a new order to store the items that were split into. It created an order the first time I did it, and now all it does is it keeps updating the products field in that order, rather than creating a new order.
  2) Next I do not know how I can update the old products (stored in the $prod array). It needs to update the products qtys after the order was split, and then if all of the qty for that product were moved to the new order it just needs to remove that product from the $prod array rather than updating the quantity.

The code is below. Please let me know if I can provide any more information to help! Thanks everyone!

Hi, I hope someone can help me.  I am trying to generate a script for our Intranet that tells me which birthdays = today.  My field in my table = d/m/y, eg 09/05/2011 (9 May 2011).  How do I get the script to just look at the day & month, not the year?  My script looks like this:

Code: [Select]
<?php

echo date("d/m/Y") . "<br />";
$myDate = date('d/m/Y');
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dbname", $con);

$sql = "SELECT * FROM detail WHERE dob='$mydate'";
$result=mysql_query($sql);
echo mysql_num_rows($result);

?>

First
Since I first started learning PHP, I've been writing code for forms like this:

$name = $_POST["name"];

if ($name == "") {
echo "You didn't type anything";
}

I've written scripts like this and tested them on a GOdaddy server, and they always worked fine.

Now, after testing scripts like that on my own server (WAMP2 [PHP5, Mysql, Apache]), I get an error saying "Unidentified index: name", and so I have to nest that if statement AS WELL AS the variable assignment inside another if statement like this:

if (isset ($_POST["name"])) {
$name = $_POST["name"];
if ($name == "") {
echo "you didn't type anything.
}
}

The error doesn't actually stop the script from running, but a medium sized box appears in the browser with the error message contained that's after the element in the document of which is getting an invalid error.

Which way is truly the correct way? Because now that I have to use the second way in order for my scripts to run correctly on my own server, I have to write more code and it all gets disorganized and more complicated to read.

So...is this a configuration thing that I can tweak in WAMP2 to stop messages like that from popping up? Or is the second way the way you're supposed to do it?

Also, I was wondering why ereg got deprecated and what the replacement of it is in PHP5? I've asked before and even googled it but I simply get taken to a "Pearl" function on PHP.net. I'm not sure what it is, or how to use it, and haven't got any hints from either PHP.net or anywhere else.

Any suggestions?

Hello all.  I'm pretty new to this, but I'm trying to build a script that will write random questions for a quiz app that I'm working on.  The data is contained in two different tables.  I'm trying to randomize the question order that is spit out, as well as randomize the answer order that is displayed.  The output has to be in the specific JSON string that is denoted in the code.  There are no errors when I go the url that I load the script, however, the string is not populated with any of the data from my tables (it is just an empty set of strings in the JSON format that the program requires.  Could someone please take a look at this and tell me where I'm going wrong.  I've checked that the query is pulling from the correct databases so I know that's not the problem.  Thank you in advance.
