PHP - How Could I Retrieve Ipad1 Hardware Information

Hello, I have a booking system which has time and date fields and if someone tries to book, for example, on 01/01/2011 at 09:00, when this slot is already taken, an error would be produced - which is fine. However I'm not sure in telling them what hours are available.

There are 9 available times: 09,10,11,12,13,14,15,16,17:00.

I will need to perform an sql query to gather all the times on the inputted date, I'm guessing a for loop would be the most efficient way?

The only way I could think of is using multiple IF queries, for example:

Code: [Select]
<?php
$sql = "SELECT `Hour` FROM `jobs` WHERE `Hour` = '09:00:00' AND Day ='$Day' AND Month ='$Month' AND Year ='$Year'";
$result = mysql_query($sql);
if(mysql_num_rows($result) > 0){
$09Available = 'n'; // Time not available
}else{
$09Available = 'y';
}

$sql = "SELECT `Hour` FROM `jobs` WHERE `Hour` = '10:00:00' AND Day ='$Day' AND Month ='$Month' AND Year ='$Year'";
$result = mysql_query($sql);
if(mysql_num_rows($result) > 0){
$10Available = 'n'; // Time not available
}else{
$10Available = 'y';
}

$sql = "SELECT `Hour` FROM `jobs` WHERE `Hour` = '11:00:00' AND Day ='$Day' AND Month ='$Month' AND Year ='$Year'";
$result = mysql_query($sql);
if(mysql_num_rows($result) > 0){
$11Available = 'n'; // Time not available
}else{
$11Available = 'y';
}

?>

etc. etc..

How would I go about creating a more efficient method?

Thank you, Jack.

Hi,

I am not very good with php but this code was kindly given to me by mdjamato, except I added a variable $markGradeSum to add all the $markGrade. Problem is that I will get notice saying undefined variable $markGradeSum because the $markGradeSum is in the foreach loop which it needs to be in for the right calculation but where I want to output the variable is in the while loop in this line:

Code: [Select]
$output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong> <strong>Grade</strong>  <br><strong>Year:</strong> {$row['Year']  $markGradeSum}</p>\n";
Below is whole code:

Code: [Select]
<?php
     
     if($num ==0){
    echo "<p>Sorry, No Records were found from this Search</p>";}
    else{
    
  function outputModule($moduleID, $moduleName, $sessionData)    
  
  {        
  
  if(!count($sessionData)) { return false; }        
  
  $markTotal = 0;        
  $markGrade = 0;
  $weightSession = 0;
  $markGradeSum = 0;
  $grade = "";
  $sessionsHTML = "";
  $courseHTML = "";
  
  foreach($sessionData as $session)        {

   $markTotal += round($session['Mark'] / 100 * $session['SessionWeight']); 
   $weightSession  += ($session['SessionWeight']);  
   $markGrade = round($markTotal /  $weightSession * 100);
   $markGradeSum = round($markGrade);
   
if ($markGrade >= 70){
$grade = "A";}      

else if ($markGrade >= 60 && $markGrade <= 69){
$grade = "B";}

else if ($markGrade >= 50 && $markGrade <= 59){
$grade = "C";}

   }        
   
   $moduleHTML = "<p><br><strong>Module:</strong> {$moduleID} - {$moduleName} <strong>Module Mark:</strong> {$markTotal} <strong>Mark Percentage:</strong> {$markGrade} <strong>Grade:</strong> {$grade} </p>\n";

     if($studentId != $row['StudentUsername'])        {            
     
     //Student has changed              
     $studentId = $row['StudentUsername'];                    
     
     $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";

     //Add session data to array for current module      
     
     $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);    
     
     }    //Get output for last module  
     
      $output .= outputModule($moduleId, $moduleName, $sessionsAry);   
      
       //Display the output    
       echo $output;

      }
  }
    ?>

How can I retrieve the variable so it doesn't come up with the notice but be able to display $markGradeSum to the places I want them in (one in foreach loop for calculation and other in while loop for output).

Thank You

I'm doing this activity where a user chooses a base timezone and when the user clicks convert the current time in the selected GMT will be converted to GMT-11 to GMT+13.

As of now, I have these codes:
act09_view.php:
Code: [Select]
<?php
session_start();
    
    $s="GMT ";
    echo "Select the base time zone:</br>";
   
    for($n=-11;$n<=13;$n++)
    {
        if ($n>=0)
            $s="GMT +";
        $gmt[]=$s . $n . "</br>";
    }

    echo "<select name='gmt'>";
    foreach ($gmt as $value) 
    {
        echo '<option value="' . $value . '">' . $value . '</option>\n';
    } 
    echo '</select>';
    //$_SESSION['value']=$value;
 ?>
<form action="act09_process.php">
       </br><input type='submit' value='Convert'/>
</form>

act09_process.php:
Code: [Select]
<?php
session_start();
//$value=$_SESSION['value'];
//echo $value;

date_default_timezone_set('Asia/Manila');
$gmttime=date('M j, Y g:i:s A');
echo "The current date and time at" . " is " . $gmttime;
?>
I've tried using session variables. I think I executed them incorrectly. 

The output is supposed to look like this:

Hi, I want to be able to retrieve records from db tables to build an xml file. The problem I am having is that I don't know how to retrieve a value after using foreign key to get appropriate value. You see below I want to make a new attribute to store to var $newAttr.

Code: [Select]
<?php
$doc=new DOMDocument();
mysql_connect("localhost","root");
mysql_select_db("xmlDB");

$edges=mysql_query("SELECT * FROM edge");
while($row=mysql_fetch_assoc($edges)) {
if($row['flag']=='val') {
$curValue=mysql_query("SELECT val FROM value,edge WHERE val.edge_id=edge.edge_id");
if($curRowIsAttribute=mysql_query("SELECT is_Attribute FROM value,edge WHERE value.is_Attribute='Y' AND value.edge_id=edge.edge_id")) {
//create attribute node
$newAttr=$dom->createAttribute();//HELP HERE PLEASE THEN I SHOULD BE ABLE TO COMPLETE NEXT TWO LINES BELOW!

//set attribute value
...

//append attribute to current element
...

}//END IF
}//END IF
}//END BIG WHILE 
?>

Any help much appreciated!

I am presuming that I set a global variable so that I can retrieve it on a different page...My filename is userid; and I will need this in many different pages. I set it thusly:

Code: [Select]
mysql_select_db($db , $link) or die("Couldn't open $db: ".mysql_error());
$long=$_SERVER['PHP_SELF'];   //get path
$text = substr(strrchr($long, "/"), 1); //get file name+extension
$UserID = trim($text, " .php"); //remove extension, leaving userid
Globals["UserID"];
and in a different file try to retrieve it thusly:  echo "user is ".$GLOBALS["UserID"];
but all I ever see is "user is"------any help appreciated.

Hello,

I am trying to figure out how to grab the latest aim status update from "http://lifestream.aol.com/stream/iragedxt"

But I can only see the Current Status if I am logged into my aim account on the website so is there a way I can log into my aim account on lifestream.aol.com and then I believe its to use curl to grab the text from the other website?

if so could someone please help me with this?

Thanks,
John

Hi everyone,   I've been running a self-written php shopping cart for the last 8 years, with lots of success.  Recently however, the credit card processor (Linkpoint) I use upgraded their gateway, and now I have a problem.   Basically, the last page of my checkout does a _POST to a specific url for their gateway.  I send through a bunch of <input> variables, some of them hidden, but all of them check out okay.  I have combed over their specs, made sure I'm not sending any bad characters, made sure I've got the right format for the fields they want, etc...    Right now the transaction is successful, the customer's card is charged, but Linkpoint's system is returning an error message: We are unable to process your request due to invalid data.   Long story short, their support staff has asked me to "send them the xml string" via email.  I have no idea how to do this (even after spending a few hours online trying to figure it out).   Is there a simple way to generate the xml string that's being passed during the _POST?  Some kind of php code I can incorporate into my final checkout page, run a test transaction, and maybe write the string out somewhere so I can get it to them?   Any help you guys could give me would be greatly appreciated.  Thanks in advance!

and here is the code for show.php

if($id = isset($_GET['prodID']))

$q = "SELECT `prodID`, `product`, `prod_descr`, `catID`, `dirID`, `price`, `stock` FROM product WHERE `prodID`='{$_GET['prodID']}'";
$r = mysqli_query($dbc, $q);
while($row = mysqli_fetch_array($r))

echo $row['product'];

echo "<br />";
echo $row ['dirID'];
echo "<br />";
echo $row['price'];
echo "<br />";
echo $row['stock'];
}
}


What I want is to try and retrieve the id of the last record inserted in add_product and pass it into show.php, but I get this error message.

Hi!
I am trying to implement the comment feature.
After a user selects a recipe from the search results (http://razor.ischool.utexas.edu/~nem/project/index.php scroll down to choose a recipe from the search results), the recipe page is displayed. The user may leave a comment at the bottom of the recipe page if she wishes to. The comment would be recorded in a mysql table and be displayed along with other comments for this particular recipe.

The problem is that when the user has entered the comment and name and hits "Add my comment", this error appears: Notice: Undefined index: id in /.../recipeText_w.php on line 57 error retrieving proteins data

While I understand it happens because the recipe Id ($_GET['id']) becomes unavailable after the comment and name are submitted, I am not sure how to make the recipe ID available again so that the same recipe page is displayed.

The script is attached. I will appreciate your advice.

What php method is good for getting file from a .xml sheet ?

I have a form where you can pick all the days in the week. When the form is posted my code finds the date of the day you picked that most recently went by. Then the code takes that date, and echos the date of every day of the week that you picked that comes after that date for a year.
But for some reason he thinks we're in 2009, even though i know the date puts out that we're in 2010.

Here's the code:

<?php
//function
if(isset($_POST['submit'])) {
function nextWeeksDay($date_begin,$nbrweek)
{
$nextweek=array();
for($i = 1; $i <= $nbrweek; $i++)  { // 52 week in one year of course
$nextweek[$i]=date('d-m-y', strtotime('+'.$i.' week',$date_begin));
}
return $nextweek;
}
//Get what user posted as day, and find the date of the past day gone.
$roday = $_POST['day'];
echo $roday;
echo date('d-m-y',strtotime('last ' . $roday));
$sistdag = date('d-m-y',strtotime('last ' . $roday));
/// end function
/// example of a select date
// var
$date_begin = strtotime($sistdag); //D Day Month Year  - like function format.
$nbrweek=52;
// call function
$result=nextWeeksDay($date_begin,$nbrweek);
// Preview
for($i = 1; $i <= $nbrweek; $i++)  {
echo '<br> - '.$result[$i];
}
}
?>

All help appreciated!
