PHP - Getting Extra Fields In For Loop

Hey guys,   Thank you in advance... here is my situation, I have a form with three (3) fields in it, the 'student name' is unlimited textfield with an "add more" button to it and I have two select fields ('number of shirts' and 'trophies') that depend on the number of entries for 'student name'...   I want to create the select fields based on this math, for as many 'student name' entries:   1- i want to have the select form for 'number of shirts' to be 0 up to that number... so if there are 6 'student name' entries, the select options will be 0,1,3,4,5,6,7 2- I want to have the select form for 'trophies' to be 5 'student name' entries to 1 'trophies', for example if there are 6 'student name' entries, the select options will be 0,1... if there are 13 entries, options will be 0,1,2... So if there are less than 5 'student name' entries, the select field will not show (hidden)   of course if there are no 'student name' entries, these two fields won't show up (hidden)   let me know if that make sense and ANY help or directions will be GREATLY APPRECIATED.   Thanks guys!  

Hey.   So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:

$firstArray = array(
'row1' => array(
'dates' => array(
'2014-01-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each.   And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..

$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}

Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested.   This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance.   In short my question is, are there any better methods of handling this with the data setup we currently have?

Below is my output on the browser:

    Student: Kevin Smith (u0867587)
    Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
    Year: 3
   
   
    Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B
   
    Session: AAB Session Mark: 72 Session Weight Contribution 20%
   
    Session: AAE Session Mark: 67 Session Weight Contribution 40%


    Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B
   
    Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.
   
    Below is the code:

Code: [Select]
    $sessionMark = 0;
    $sessionWeight = 0;
    $courseMark = 0;
   
    $output = "";
   
    $studentId = false;
    $courseId  = false;
    $moduleId  = false;
   
    while ($row = mysql_fetch_array($result))
    {
   
   
    $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
    $sessionWeight  += ($row['SessionWeight']);
        $courseMark = ($sessionMark /  $sessionWeight * 100);
   
          if($studentId != $row['StudentUsername'])
        {
   
            //Student has changed
            $studentId = $row['StudentUsername'];
   
            $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";
   
        }
             
        if($courseId != $row['CourseId'])
        {
   
            //Course has changed
            $courseId = $row['CourseId'];
   
            $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong>  <br><strong>Year:</strong> {$row['Year']}</p>\n";
   
        }
   
        if($moduleId != $row['ModuleId'])
        {
   
            //Module has changed
            if(isset($sessionsAry)) //Don't run function for first record
            {
   
                //Get output for last module and sessions
                $output .= outputModule($moduleId, $moduleName, $sessionsAry);
            }
   
            //Reset sessions data array and Set values for new module
   
            $sessionsAry = array();
            $moduleId    = $row['ModuleId'];
            $moduleName  = $row['ModuleName'];
        }
             
        //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;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?

Hey guys,

Got another question im hoping someone can help me with.

I have a foreach loop (for use in a mysql query):

   foreach ($interests as $interest) {
       $query .= "($id, $interest), ";
   }

problem is i do not want the comma(,) in the last loop.

Is there some kinda of function i can use so it does not insert it on last loop?

Or should i just use a for loop with a nested if loop? something like ;

   for($i=0; $i < count($interests); $i++){
      $query .=
      "($id, '$interests[$i]')";
      if($i + 1 < count($interests)) {
         $query .= ", ";
      }
      }


Cheers guys

I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong!

The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match)

The if loop displays ALL listings with the same name (counts them all) so there are no unique listings!


<?php

$posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'";
$posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!");

/* While Loop  */
while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
}

/* For Loop  */
$posts_by_city_row = mysqli_fetch_array($posts_by_city_results);
 
for ($i=0; $i<sizeof($posts_by_city_row); $i++) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
 }

?>

Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below):

Hello

I was wondering if anyone could help me.
 


I have bought a script that are encoded is something that i cant change or read, and i have ask the owner how to put a {user} at the end of every hyperlink
so are going to a other site, but he said you need a external script to do that. So was wondering if anyone could help me.

Im using a database where all the user are etc

But If i go to google.com and login as Bobmartin

I will be at google.com/home

Then i click on a hyperlink inside google.com/home that will bring me to a other side

Lets say the hyperlink (other site) is www.phpfreaks.com/profile/

So when i begining to redirect to www.phpfreaks.com/profile/ the script will add {user} from the database

So at the end i will be redirect to www.phpfreaks.com/profile/Bobmartin


The hyperlink is generated in a unique code so i cant just add {user} it must be a external script i need to use.


So to say it fast

I want to add /{user} for every hyperlink that is redirect to another site without add {user} direct to the hyperlink for example www.google.com/{user}, the hyperlink must me www.google.com



Well i hope you guys understand  this, im not the best person to explain things so

Also my english suck so dont judge me

Hi i've recently moved hosting servers as I had severe lag issues with my shared hosting. Since i've brought a dedicated linux server with apache and php. Since the move i get extra chars with the following code

Code: [Select]
<?PHP
define( "MESSAGE", "Testing Testing 123" );

if(isset($_GET['message']))
{
die(MESSAGE);
}
?>

My application SHOULD receive back "Testing Testing 123" like it used to with my old shared hosting. Instead now it receives the following:

Code: [Select]
2f
Testing Testing 123
0

And i cannot figure this out for the life of me. I'm expecting something silly to be the cause but would appreciate some guidance on this.

Thanks

Hi there

I followed this post

http://www.phpfreaks.com/forums/index.php?topic=95426.0

to get a multi-column layout of search results.

All's well but I seem to have an extra blank row at the bottom of the table.

This is my code for the table

Code: [Select]
echo '<table width="800px" class="center" border="1">';
echo '<td>'; 

if($result && mysql_num_rows($result) > 0)
{
    $i = 0;
    $max_columns = 3;
    while ($list = mysql_fetch_array($result))       
   {
       // make the variables easy to deal with
       extract($list);

       // open row if counter is zero
       if($i == 0)
          echo "<tr>";
          echo '<td><a href="word.php?w=' . $list['word'] . '">' . $list['word'] . '</a></td>';
   
       // increment counter - if counter = max columns, reset counter and close row
       if(++$i == $max_columns)
       {
           echo "</tr>";
           $i=0;
       }  // end if
   } // end while
} // end if results

// clean up table - makes your code valid!
if($i < $max_columns)
{
    for($j=$i; $j<$max_columns;$j++)
        echo "<td>&nbsp;</td>";
}
 echo '</tr>';
 echo '</table>';

Any ideas on how not to have it there?

Thanks in advance.

I have an email form that I use to generate email messages to a club distribution list. I add the body of the message from a form that sends that message to a php script. The emails are a mix of html directly from the script as well as what is sent to the script from the web page form.

Example:
$mailmessage = '<html><body>header of message' . $MessageFromForm . 'footer of message </body></html>';

**where $MessageFromForm is requested from the form and is the body of the email message.

The html header and footer of the message look fine, but the code that came from my html form does not work properly. That code replaces a ' with \', and the html tags do not work. I do have the following included in my headers:

$headers = "MIME-Version: 1.0" . "\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\n";

Any ideas on what could cause this?

So I'm generating an XML response for Google Maps and this is how my method looks:

		// Start XML file, create parent node
		$dom = new DOMDocument("1.0");
		$node = $dom->createElement("markers");
		$parnode = $dom->appendChild($node);

		header("Content-type: text/xml");

		/*
		 * Iterate through the rows, adding XML nodes for each
		 * Have to do it the ugly way so results aren't pulled twice
		 * (xml and php can't be passed within same array because headers are changed)
		*/
		foreach ($results as $row){
		  $node = $dom->createElement("marker");
		  $newnode = $parnode->appendChild($node);
		  $newnode->setAttribute('id', $row['id']);
		  $newnode->setAttribute('logo', $row['logo']);

Hello PHPFreaks!
I have a question for somebody to answer 

Code: [Select]

 $caption=$_POST['caption']; 
 $ip=$_POST['ip']; 
 
 //Writes the information to the database

 echo "Sorry, there was a problem uploading your file."; 
 } 
 ?>
When pictures are uploaded; they upload the name they have named them.

Is it possible to add to the script $username somewhere to the file name?
For example; DSC_0077_SOLAR.JPG

Thanks for your time!

EDIT.  When starting this post, I thought it was causing the browser to make an extra request to the server.  I've since found this wasn't the case, however, didn't change the title of this post, and can't seem to change it to something like "Critique of file caching script"   I am trying to cache a file, and put together the following script.  I put the following in the browser:

https://test.sites.example.com/administrator/index.php?cid=2&controller=sell&id=643341356

... and Apache will rewrite as:

https://test.sites.example.com/index.php?admin=administrator&cid=2&controller=sell&id=643341356

index.php includes the following line:

<script src="/lib/js/clientConstants.php?b=1" type="text/javascript">

Hi everyone, I used to know the function, but it was a very long time ago, for when you need to just extract a single value from a query... instead of having to use mysql_fetch_assoc in a while loop to build an array...

e.g.
Code: [Select]
$TheResultingFieldValue = mysql_fetch_SOMETHING(mysql_query("SELECT aField FROM aTable WHERE anotherField = 'aCondition'"));

I shouldn't even be posting this but I"m tired and want to get this last part done by the end of the night. This script works however with the echoed "sortorder" its getting in the way of what's echoed for the submitmenuitem because its showing up as say 1good after form submission and not sure how to get it to not show up like that after form submission because that sortorder is getting echoed on document is ready.
