Question

我不知道我在这里做错了什么.. 我在表中有大约125种产品，但我只得到表中的最后一个产品，所以它只显示一个项目...这是一个简单的计算器，为销售人员和客户提供他们需要多少盒子以及它需要多少会快速估算。感谢您提前帮助..

Answer 1

你的循环没有附加到$ TileNameList，因为它存在于它之外。它实际上取代了它的价值。尝试：

<?php

include('admincik/config.php');
include ('birlikte/ac.thumbs.php'); 

//Retrieves data from MySQL 

 $data = mysql_query("SELECT * FROM Calculator ORDER BY isim") or die(mysql_error()); 
 //Puts it into an array 
 while($info = mysql_fetch_array( $data )) 
 { 
$resim = $info['resim'];
$isim = $info[isim];
$boyut = $info[boyut];
$pcs = $info[adet];
$sqft = $info[sqft];
$price = $info[price];
$TileNameList .= "<option value=\"$sqft\">$isim $boyut</option>";   // NOTE THE .=
}
/////////Formdan gelen yada Giden//////////////
$length =htmlspecialchars(stripslashes($_POST['Length'])); 
$width =htmlspecialchars(stripslashes($_POST['Width'])); 


/////Matematiksel islemler/////////

$equals = $length * $width;
$box = round($equals / $sqft);
$sqftbox = $box * $sqft;
$TotalPrice = $sqftbox * $price

?>
<div class="ana">
  <table width="900" height="199" border="1">
    <tr>
      <td width="150">Name</td>
      <td width="150">Length</td>
      <td width="150">Width</td>
      <td width="150">Total Sqft Area</td>
      <td width="200">Box Needed /Total Sqft</td>
      <td width="100">Price</td>
    </tr>
    <tr>
      <td><form id="form5" name="form5" method="post" action="">
        <select name="TileName" id="TileName">
<?php echo ($TileNameList); ?>
        </select>
      </td>
      <td><input name="Length" type="text" id="Length"/></td>
      <td><input type="text" name="Width" id="Width"/></td>
      <td><input type="text" name="Sqft" id="Sqft" value="<?php echo ($equals); ?>"/></td>
      <td><?php echo "You will need <span style=\"color:red\">$box</span> Boxes<br> Which is <span style=\"color:red\">$sqftbox</span> "; ?></td>
      <td><?php echo "$$TotalPrice"; ?></td>
    </tr>
