geben Sie einen Datensatz aus der Datenbank

Question

Danke für die Antwort. Jetzt ist es Arbeit, aber ich habe nächstes Problem. ich neu gemacht, ein Verfahren Datensätze aus der Datenbank anzuzeigen:

public $id, $nazwa, $quantity, $data, $godzina, $sn, $added, $kategoria, $numrows; 

    public function magazyn() { 
     $resultmag = $this->magazyn = $this->conn->prepare("SELECT * FROM `products` ORDER BY `id`"); 
     $resultmag = $this->conn->set_charset("utf8"); 
     $resultmag = $this->magazyn->execute(); 
     $resultmag = $this->magazyn->get_result(); 

     if ($isset = $resultmag->num_rows > 0) { 
      while ($row = $resultmag->fetch_object()) { 
      $this->id = $row->id; 
      $this->nazwa = $row->nazwa; 
      $this->quantity = $row->quantity; 
      $this->data = $row->data; 
      $this->godzina = $row->godzina; 
      $this->sn = $row->sn; 
      $this->added = $row->added; 
      $this->kategoria = $row->kategoria; 
      } 
      $this->numrows = $resultmag->num_rows; 
     } else { 
      echo "No results database"; 
     } 
    } 

    function __toString() { 
     return (string) $this->numrows; 
    } 

    //------------------------------- 
    $mag = new Magazyn(); 
    $mag->magazyn(); 

    ?> 
      <table class="table table-bordered"> 
       <tr><th style='text-align:center'>ID</th><th style='text-align:center'>DODAŁ</th><th style='text-align:center'>NAZWA</th><th style='text-align:center'>KATEGORIA</th><th style='text-align:center'>SERIAL</th><th style='text-align:center'>ILOŚĆ</th><th style='text-align:center'>DATA</th><th style='text-align:center'>GODZINA</th><th style='text-align:center' colspan='2'>AKCJA</th></tr> 
       <?php 
    $color = NULL; 
    $color1 = '#99bbff'; 
    $color2 = '#b3ccff'; 

    $color == $color1 ? $color = $color2 : $color = $color1; 
    echo "<tr class='active'>"; 
    echo "<td align='center' style='background-color:" . $color . ";'>" . $mag->id . "</td>"; 
    echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=userpanel&user=" . $mag->added . "'>" . $mag->added . "</a></td>"; 
    echo "<td align='center' style='background-color:" . $color . ";'>" . $mag->nazwa . "</td>"; 
    echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=category&cat=" . $mag->kategoria . "'>" . $mag->kategoria . "</a></td>"; 
    echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=editserial&sn=" . $mag->sn . "'>" . $mag->sn . "</a></td>"; 
    echo "<td align='center' style='background-color:" . $color . ";'>" . $mag->quantity . "</td>"; 
    echo "<td align='center' style='background-color:" . $color . ";'>" . $mag->data . "</td>"; 
    echo "<td align='center' style='background-color:" . $color . ";'>" . $mag->godzina . "</td>"; 
    echo "<td align='center'><a href='panel.php?page=magazyn&action=edit&sn=" . $mag->sn . "&nazwa=" . $mag->nazwa . "&kategoria=" . $mag->kategoria . "&id=" . $mag->id . "'</a><button class='btn btn-default'>Edytuj</button></td>"; 
    echo "<td align='center'><a href='panel.php?page=magazyn&action=delete&sn=" . $mag->sn . "'</a><button class='btn btn-default'>Usuń</button></td>"; 
    echo "</tr>"; 

Das Problem ist, dass es zeigt nur einen Datensatz aus der Datenbank. Als ich während Echo hinzu:

while ($row = $resultmag->fetch_array()) { 
    echo $this->id = $row['id']; 
    echo $this->nazwa = $row['nazwa']; 
    echo $this->quantity = $row['quantity']; 
    echo $this->data = $row['data']; 
    echo $this->godzina = $row['godzina']; 
    echo $this->sn = $row['sn']; 
    echo $this->added = $row['added']; 
    echo $this->kategoria = $row['kategoria']; 
} 

Zeigt alle Datensätze, sondern durch:

$mag->magazyn(); 

Answer 1

Wie Dagon Kommentar oben sagt, Ihre Werte zu einem mehrdimensionalen Array hinzuzufügen. Statt

public $id, $nazwa, $quantity, $data, $godzina, $sn, $added, $kategoria, $numrows; 

Just do

public $records = array(); 
public $numrows; 

Dann werden Sie alle Datensätze zu diesem Array anhängen:

public function magazyn() { 
    $resultmag = $this->magazyn = $this->conn->prepare("SELECT * FROM `products` ORDER BY `id`"); 
    $resultmag = $this->conn->set_charset("utf8"); 
    $resultmag = $this->magazyn->execute(); 
    $resultmag = $this->magazyn->get_result(); 

    if ($isset = $resultmag->num_rows > 0) { 
     while ($row = $resultmag->fetch_object()) { 
     $record['id'] = $row->id; 
     $record['nazwa'] = $row->nazwa; 
     // etc... Add all like above 

     $this->records[] = $record; 
     } 
     $this->numrows = $resultmag->num_rows; 
    } else { 
     echo "No results database"; 
    } 
} 

Dann in Ihrem HTML Sie Schleife über $mag->records:

<table class="table table-bordered"> 
    <?php foreach ($mag->records as $record) : ?> 
     <tr><th style='text-align:center'>ID</th><th style='text-align:center'>DODAŁ</th><th style='text-align:center'>NAZWA</th><th style='text-align:center'>KATEGORIA</th><th style='text-align:center'>SERIAL</th><th style='text-align:center'>ILOŚĆ</th><th style='text-align:center'>DATA</th><th style='text-align:center'>GODZINA</th><th style='text-align:center' colspan='2'>AKCJA</th></tr> 
     <?php 
     $color = NULL; 
     $color1 = '#99bbff'; 
     $color2 = '#b3ccff'; 

     $color == $color1 ? $color = $color2 : $color = $color1; 
     echo "<tr class='active'>"; 
     echo "<td align='center' style='background-color:" . $color . ";'>" . $record['id'] . "</td>"; 
     echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=userpanel&user=" . $record['added'] . "'>" . $record['added'] . "</a></td>"; 
     echo "<td align='center' style='background-color:" . $color . ";'>" . $record['nazwa'] . "</td>"; 
     echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=category&cat=" . $record['kategoria'] . "'>" . $record['kategoria'] . "</a></td>"; 
     echo "<td align='center' style='background-color:" . $color . ";'><a href='panel.php?page=editserial&sn=" . $record['sn'] . "'>" . $record['sn'] . "</a></td>"; 
     echo "<td align='center' style='background-color:" . $color . ";'>" . $record['quantity'] . "</td>"; 
     echo "<td align='center' style='background-color:" . $color . ";'>" . $record['data'] . "</td>"; 
     echo "<td align='center' style='background-color:" . $color . ";'>" . $record['godzina'] . "</td>"; 
     echo "<td align='center'><a href='panel.php?page=magazyn&action=edit&sn=" . $record['sn'] . "&nazwa=" . $record['nazwa'] . "&kategoria=" . $record['kategoria'] . "&id=" . $record['id'] . "'</a><button class='btn btn-default'>Edytuj</button></td>"; 
     echo "<td align='center'><a href='panel.php?page=magazyn&action=delete&sn=" . $record['sn'] . "'</a><button class='btn btn-default'>Usuń</button></td>"; 
     echo "</tr>"; 
    endforeach; 
    ?>
