PHP - Display All Visitor Request Variables

Doing something wrong, but don't see it.  How should one retrieve a POST parameter?  My $request->toArray()['html'] works, but I am sure it is not the "right way".

<?php
namespace App\DataPersister;
use ApiPlatform\Core\DataPersister\DataPersisterInterface;
use Symfony\Component\HttpFoundation\RequestStack;

class ArchivePersister implements DataPersisterInterface
{
    public function __construct(RequestStack $requestStack)
    {
        $request = $requestStack->getCurrentRequest();
        syslog(LOG_ERR, '$request->getMethod(): '.$request->getMethod());
        syslog(LOG_ERR, '$request->getContent(): '.$request->getContent());
        syslog(LOG_ERR, '$request->request->get(html): '.$request->request->get('html'));
        syslog(LOG_ERR, '$request->query->get(html): '.$request->query->get('html'));
        syslog(LOG_ERR, '$request->get(html): '.$request->get('html'));
        syslog(LOG_ERR, '$request->toArray(): '.json_encode($request->toArray()));
        syslog(LOG_ERR, '$request->toArray()[html]: '.$request->toArray()['html']);
    }
}

output

$request->getMethod(): POST
$request->getContent(): {"project":"/projects/1","description":"","html":"<p>{{ project_name }}</p>"}
$request->request->get(html):
$request->query->get(html):
$request->get(html):
$request->toArray(): {"project":"\/projects\/1","description":"","html":"<p>{{ project_name }}<\/p>"}
$request->toArray()[html]: <p>{{ project_name }}</p>

i am having issues getting the variables to show up on localhost server within the body element. is it something in the codes or something in the php.ini settings? here is some sample code
Code: [Select]
<h1>Skyward Aviation</h1>

<h2>Contact Information</h2>
<form action="ContactUpdate.php" method="get">
<table frame="border" rules="cols">
<colgroup width="50%" />
    <colgroup width="50%" />
    <tr>
        <td align="right" valign="top">
            <p>First Name <input type="text" name="first_name" value="<?= $First ?>" size="36" /></p>
                <p>Last Name <input type="text" name="last_name" value="<?= $Last ?>" size="36" /></p>
                <p>Phone <input type="text" name="phone" value="<?= $Phone ?>" size="36" /></p>
            </td>
            <td align="right" valign="top">
            <p>Address <input type="text" name="address" value="<?= $Address ?>" size="40" /></p>
                <p>City <input type="text" name="city" value="<?= $City ?>" size="10" />
                    State <input type="text" name="state" value="<?= $State ?>" size="2" maxlength="2" />
                    Zip <input type="text" name="zip" value="<?= $Zip ?>" size="10" maxlength="10" /></p>
            </td>
       </tr>
</table>
<p><input type="hidden" name="PHPSESSID" value='<?php echo session_id() ?>' />
<p><input type="submit" value="Submit" /></p>

</form>

In the page is shows <?= $First ?> in the area First Name textbox.

hello i have built a webpage using tables.
i might have done something wrong (except using tables) and now the results are rendered chaotically on the webpage. also here is the attached file. after the 4th article it's all messy

i have a solution but that means to insert a php tag inside another php tag, but won't work

thankyou

This code was given to me by mjdamato to help display a student and the course that student has take and within that the modules in the course and the sessions in course including module mark and grade and student's session marks and grades. I am very weak on php code as I have only done it once and that was following a php workbook 2 years ago. I am more of a database specialist. Below is the code given to me and you can also download the code from the attachment:

Code: [Select]
<?php

function outputModule($moduleID, $moduleName, $sessionData)    
  
  {        
  
  if(!count($sessionData)) { return false; }        
  
  $markTotal = 0;        
  $markGrade = 0;
  $weightSession = 0;
  $grade = "";
  $sessionsHTML = "";
  
  foreach($sessionData as $session)        {           
  
   $sessionsHTML .= "<p><strong>Session:</strong> {$session['SessionId']} <br><strong>Session Mark:</strong> {$session['Mark']}</strong> <br><strong>Session Weight Contribution</strong> {$session['SessionWeight']}%</p>\n";            
   $markTotal += round($session['Mark'] / 100 * $session['SessionWeight']); 
   $weightSession  += ($session['SessionWeight']);  
   $markGrade = round($markTotal /  $weightSession * 100);
   
if ($markGrade >= 70){
$grade = "A";}      

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

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

    $studentId = false;    
    $courseId  = false;

    while ($row = mysql_fetch_array($result))    {

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

      //Course has changed           
       $courseId = $row['CourseId'];                    
       
       $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong> <strong>Grade</strong>  <br><strong>Year:</strong> {$row['Year']}</p>\n";           
       
        }

 //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();

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

      }
  }
    ?>
Below the what this code outputs:


Student: Mayur Patel (u0867587)
Course: INFO101 - Bsc Information Communication Technology       Course Mark
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%


If you look above it shows that there is nothing in the Course Mark: section, what Course Mark is suppose to do is total up all the module mark percentages and then divide it by the number of modules. So the calculation will be adding up all the Code: [Select]
$markGrade and dividing it by count Code: [Select]
$ModuleID. In examle above it will be 68 (mark percentage for 1st module) + 62 (mark percentage for 2nd  module) / 2 (number of modules in the course). So the Course Mark should equal 65. 

The problem is that all of the calculations are in the foreach loop but where the course details and where the course marks are going to be placed are in the while loop. So the problem is that if the total Course Mark (lets say we call in $totalCourse) is displayed in the while loop it will provide an undifined index as the calculation will be placed with the other calculations in the foreach loop which is outside the while loop, if I do the calculation with in the while loop, it will only choose the 1st module mark percentage and divdie it by the first module only, this is obviously incorrect as it sohuld try and do this for all modules hence why my calculations are in the foreach loop which does this.

So how will change the code so that the course details can go from the while loop and be placed in the foreach loop so then I can include the calculation in the foreach loop.

Thank You and hopefully you understand it, just read it very carefully to understand it, it is very simple what I want to achieve but I do not know how to do it.

Hey,

Well when they view my website from home. We get the same (public)ip. Is there a way to tell that these people are not the same person, not using the same ip, because i am saving data from the ip(visitors). The others will get the same date too, because of the same ip. Or is there any other way to get a unique id(number) from visitors?

Hope you understand.
Cheers.
