後期價值的文本字段OrderForm

我有多本書，人們可以訂購。所有這些書都存儲在MySQL數據庫中。人們可以將值（INT）輸入到文本字段中。示例：Book One值= [5]。但是當我輸入提交時，它只會顯示該文本框的最後輸入值。後期價值的文本字段OrderForm

我該如何安排，如果人們只在某些文本字段中輸入值，然後點擊提交，他們會看到他們訂購的產品和價值。謝謝:)

我的代碼

  <table width="990"> 
     <form name="form" action="<?php $_SERVER['PHP_SELF']; ?>" method="post">

     </tr> 
<?php 
    // Laat Resultaten zien 
    $s = "SELECT * FROM producten ORDER BY id ASC"; 
    $sql = (mysql_query($s))or die ("FOUT: " . mysql_error()); 
    while($row = mysql_fetch_array($sql)) 
    { 
     $id = $row['id']; 
     echo "<tr>";

一開始，你的'SELECT'語句需要一個'WHERE'語句。如'SELECT * FROM producten WHERE bestelnummer =「5」ORDER BY id ASC' – Dorian

你會過得更好使用數組所以使用

<input type='text' name='nummer[".$id."]' title='nummer".$id."' class='aantal' maxlength='4' />

然後更換

$_POST['nummer".$id."'];

與

foreach($_POST['nummer'] as $value) { 
    echo $value; 
}
