PHP - Breadcrumb Problems

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!

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?

I want to gettwitter feeds,

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);

?>

why cant i login in i have everything in my db
this is the code

Code: [Select]
<?php
session_start();
$email= $_SESSION['email'];
?>
<?php

if(loginbtn){
$email = $_POST['email'];
$password = $_POST['password'];

if($email && $password){


//connection to db
require 'scripts/connect.php';

$query = mysql_query("SELECT * FROM users WHERE email='$email'");
$numrows = mysql_num_rows($query);

if($numrows == 0){

$rows = mysql_fetch_assoc($query);

$dbemail = $row['email'];
$dbpassword = $row['password'];

if($password==$dbpassword){

$_SESSION['email'] = $dbemail;

echo "You have been logged in as $email"."<br/>";
 
}else
    echo "You enter a incorrect password";
}else
    echo "This person does not exsit";
}else
    echo "You did not fill in all the fields";
}else
    echo "$form";
    
$form = "<form action='login.php' method='POST'>
<table>
<tr>
<td>Email</td>
<td><input type='email' name='email'></td>
</tr>
<tr>
<td>Password</td>
<td><input type='password' name='password'></td>
</tr>
<tr>
<td></td>
<td><input type='submit' name='loginbtn' value='Login'></td>
</tr>
</table>
</form>";

echo $form;

?>

It seems like every new language I learn, I get this exact same issue. I want to make a clickable link that will go to "viewpost?postid=" and then add the value of a variable. The variable is an array. Here's what I'm trying. I'm not really sure why it doesn't work:

<?php 
$poststr = "<a href=\'viewpost.php?"+$postid[$num]+"\'>View This Post</a>";
echo $poststr;
?>

$postid[$num] in this example should be an integer. But what it outputs is really weird. It's not "View This Post" as a link, which is what I want. It just outputs the value of the variable $postid[$num] with no link. Can someone tell me what my problem is?

I have a config file that lists a file like so..

Code: [Select]
$file1 = 'storagefolder/mydatabase.txt';
How can I delete the file "mydatabase.txt" that is in another directory 'storagefolder' ?

Code: [Select]
unlink($file1);gives an error that says not such file or directory

Hi, I'm working on a script that connects to a remote API and receives information in XML.

The problem I'm having is I can't seem to get it to parse right.

The information that is received is this:
Code: [Select]
<?xml version="1.0" encoding="UTF-8"?>
<response xmlns:agent="http://www.eurodns.com/agent">

<result code="1000">
<msg><![CDATA[Command completed successfully]]></msg>
</result>

<resData>
<agent:balance currency="EUR">0.00</agent:balance>
</resData>

</response>

I'm trying to use the SimpleXMLElement class to parse it and this is the result I get:
Code: [Select]
SimpleXMLElement Object
(
    [result] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [code] => 1000
                )

            [msg] => SimpleXMLElement Object
                (
                )

        )

    [resData] => SimpleXMLElement Object
        (
        )

)

As you might notice the resData Object is for some reason empty.

I haven't done much XML parsing with PHP 5 before so I'm probably missing something.

Any help is appreciated,

Chris

Hi im pritty new to PHP used to using ASP but found PHP to be more resourcful!

Anyway, Im trying to work out how to get my script to define if a prduct fee is higher than an available account balance, but hitting brick walls!
CODE BELOW:


$Credits = 10;
$Fee = 5;

if ($Fee > $Credits){

 //NEED MORE CREDITS

}else{

//YOU CAN PURCHASE THIS ITEM

 }


But returns that 10 is not greater than 5, i guess this is because it is only taking the first digit into consideration, even if it is 12 or 15 is still says its not higher than 5 ???
Ive been at it for hours searched google and come up with nothing... please help I may be acting thick and it may be really simple but im lost!

Thanks in advance!

I'm writing a rather large script and it appears that I'm running into some require_once problems. So far I only have a few files wrote for my script..

./includes/objects/database.class.php
require_once("../../config.php");

./test.php
require_once("./config.php");
require_once("./includes/objects/database.class.php");

When I try running the test.php I get the following error:
Code: [Select]
Warning: require_once(../../config.inc.php) [function.require-once]: failed to open stream: No such file or directory in /includes/objects/database.class.php on line 27

Fatal error: require_once() [function.require]: Failed opening required '../../config.inc.php' (include_path='.:/opt/lampp/lib/php') in /includes/objects/database.class.php on line 27
However, when I run the database.class.php by itself it doesn't have any errors at all and it requires (sounds weird.. includes I guess?) the file just fine. I only get the above error from running test.php. I'm running on a local environment using XAMPP so there might be some php configuration option that I'm not aware of. I've tried doing some reading and I'm honestly not sure what could be the problem.

Help? 

I've got a comment box that connects to a MySQL database. I've got this error message here when I use the PHP include function to call on this script on my main page http://www.inkzoid.com/index.php ...

// starting the table

//displaying the shouts
getShouts();


mysql_close($l);


?>

I was told that I should put ob_start(); at the top of my page and ob_end_clear(); at the end of my page, but should that code go on the shout.php file or my index.php file (index.php is where I want my comment box to go)? I was using session_start(); but I got some error messsages about headers already being sent because I had originally used the php include function at the top of index.php to include shout.php. After reading up on it I found out that the error was caused by not having session_start(); being the first line of code. So my problem was that I wanted the comment box to be somewhere other than at the top of the page. Not sure how to move it.

Anyways I'm pretty confused right now and if someone could give me some advice it would be appreciated.
