Connection between PHP and Access DB

问题:

I'm working for weeks to try to solve this problem. I need to manage a connection between PHP and Microsoft Access Database .mdb.

My goal is to create a web page that contain a table with the fields of a database table. But my table has about 30 columns, I would like to insert only 6 of these.

Example:
Database name: DinamicoWeb
Table name: Orders
Fields name: Id Ord, Ord Date, Name, Surname, Price, Total

This is the code that I managed to write(put inside ALL columns).

config.php

<?php
define ('DBNAME',"./DinamicoWeb.mdb"); // Database name
define ('DBTBL',"Ordini"); // Table name
define ('PKNAME',"Id Ord"); // Primary Key
define ('PKCOL',0); // Posotion Primary Key
define ('LINKPK',true); // PK link for edit/delete
?>

test.php

<?php
require_once("config.php");

$cn = new COM("ADODB.Connection");
$cnStr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=".
            realpath(DBNAME).";";
$cn->open($cnStr);
$rs = $cn->execute("SELECT * FROM ".DBTBL);
$numFields = $rs->Fields->count;

// Print HTML
echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">';
echo '<html xmlns="http://www.w3.org/1999/xhtml">';

echo '<h1>GESTIONE '.DBTBL.'</h1>';
// Elenca records -----
echo ("<table class='datatable' summary='Prova dati con MS Access'>");
echo("<caption>Tabella ".DBTBL."</caption>\n");
echo("<thead><tr>\n");
for ($i=0;$i<$numFields;$i++){
    echo("<th scope='col'>");
    echo $rs->Fields($i)->name;
    echo("</th>\n");
}
echo("</tr></thead>\n");
echo("<tbody>");

$alt = false;
while (!$rs->EOF)
{
    echo("<tr>");
    for ($i=0;$i<$numFields;$i++){
      $altClass = $alt ? " class='alt'" : "";
      if (LINKPK && $i==PKCOL){
        echo "<td".$altClass."><a href='?id=".$rs->Fields($i)->value
              ."'>".$rs->Fields($i)->value."</a></td>\n";
      }
      else{
        echo "<td".$altClass.">".$rs->Fields($i)->value."</td>\n";
      }
    }
    echo("</tr>\n");    
    $rs->MoveNext();
    $alt = !$alt;
}
echo("</tbody>");
echo("</table>\n");
echo ("<p>[ <a href='?ins=1'>Inserimento nuovo record</a> ]</p>");
// Modifica record -----
if (!empty($_GET['id'])){
  $id = intval($_GET['id']);
  $rs = $cn->execute("SELECT * FROM ".DBTBL." WHERE ".PKNAME."=".$id);
  echo ("<form action='modify.php' method='post'>");
  echo ("<fieldset>");
  echo ("<legend>Modifica record</legend>");
  for ($i=0;$i<$numFields;$i++){
    if (LINKPK && $i==PKCOL){
      echo ("<label for='".$rs->Fields($i)->name."'>"
             .$rs->Fields($i)->name."</label>");
      echo ("<input type='text' readonly='readonly' name='"
             .$rs->Fields($i)->name."' value=\""
             .$rs->Fields($i)->value."\" /><br />\n");      
    }
    else {
      echo ("<label for='".$rs->Fields($i)->name."'>"
             .$rs->Fields($i)->name."</label>");
      echo ("<input type='text' name='".$rs->Fields($i)->name."' value=\""
             .$rs->Fields($i)->value."\" /><br />\n");
    }
  }
  echo ("<button type='submit' name='azione' value='modifica'>Modifica</button>");
  echo ("<button class='affiancato' type='submit' 
        name='azione' value='cancella'>Cancella</button>");
  echo ("</fieldset></form>");
}
// Inserimento record -----
elseif (!empty($_GET['ins'])){
  echo ("<form action='modify.php' method='post'>");
  echo ("<fieldset>");
  echo ("<legend>Inserimento record</legend>");
  for ($i=0;$i<$numFields;$i++){
    if ($i!=PKCOL){
      echo ("<label for='".$rs->Fields($i)->name."'>"
             .$rs->Fields($i)->name."</label>");
      echo ("<input type='text' name='".$rs->Fields($i)->name."' /><br />\n");
    }
  }
  echo ("<button type='submit' name='azione' value='inserisci'>Inserisci</button>");
  echo ("<br />");
  echo ("</fieldset></form>");
}
echo '</body></html>';
$rs->Close();
$cn->Close();
?>

PS: It's great to trasform the .php file to .html file with dynamic php inside.

PSS: And the next step would be to make also filters with combobox and checkbox

If is possible, I would add headers of columns manually and not with a While, so as to make the responsive table with jQuery and footable

For example:

<table class="footable" data-filter="#filter">
  <thead>
    <tr>
      <th data-sort-initial="descending" data-class="expand">
        [Id Ord]
      </th>
      <th data-sort-ignore="true">
        [Name]
      </th>
      <th data-hide="phone,tablet">
        [Surname]
      </th>
      <th data-hide="phone,tablet" data-type="numeric">
        [Price]
      </th>
      <th data-hide="phone" data-type="numeric">
        [Total]
      </th>
    </tr>
  </thead>

回答1:

Change

$rs = $cn->execute("SELECT * FROM ".DBTBL);

to only request the six columns

$rs = $cn->execute("SELECT [Id Ord], [Ord Date], [Name], [Surname], [Price], [Total] FROM ".DBTBL);
