Question

我有两个PHP页面 1. sup_select.php - 这是用户必须为一个项目选择多个供应商的地方 2. suppliers.php - 包含所有供应商详细信息。用户应该能够选择多个复选框，并且当用户单击提交时，复选框值必须传递到sup_select.php中的文本框。

这是我的代码。

sup_select.php

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
$nic = $_SESSION['nic'];
?>

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Add Supplier</title>


<style type="text/css">
.supadd {
}
</style>
</head>

<body>
<div class="supadd">
  <table width="1260" border="1">
    <tr align="center">
      <th width="126" scope="col">Request No.</th>
      <th width="130" scope="col">Request Date</th>
      <th width="87" scope="col">Item</th>
      <th width="127" scope="col">Item Category</th>
      <th width="168" scope="col">Requested Quantity</th>
      <th width="132" scope="col">Change Quantity</th>
      <th width="89" scope="col">Deliver Before</th>
      <th width="101" scope="col">Suppliers</th>
      <th width="90" scope="col">Forward</th>
      <th width="146" scope="col">Review Request</th>
    </tr>
    <?php 

    $result = mysql_query("SELECT * FROM ops_order_request_tbl ORDER BY request_number ASC");
while($row = mysql_fetch_array($result))
  {
    echo "<tr align='center'>";
      echo "<td>".$row['request_number']."</td>";
      echo "<td>".$row['request_date']."</td>";
      echo "<td>".$row['item']."</td>";
      echo "<td>".$row['item_cat']."</td>";
      echo "<td>".$row['requested_quantity']."</td>";
      echo "<td><input type='text'></td>";
      echo "<td>".$row['deliver_before']."</td>";

      echo "<td><form name='' method='get' action=''>
      <input name='".$row['request_number']."' type='text' value='".$checked."'><br><a href='suppliers.php'>Add Suppliers</a></form></td>";
      echo "<td><form name='' method='' action=''><input type='button' value='Forward'></form></td>";
      echo "<td><form name='' method='' action=''><input type='button' value='Review'></form></td>";
    echo "</tr>"; 

  } 

  ?>
  </table>
</div>
</body>
</html>

supplier.php

/ Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
$nic = $_SESSION['nic'];
?>

<!doctype html>

<body>
<?php 
echo "<div class='supadd'>";
  echo "<table  border='1'>";
    echo "<tr align='center'>";
      echo "<th width='126' scope='col'>Supplier Name</th>";
      echo "<th width='130' scope='col'>Supplier Address</th>";
      echo "<th width='87' scope='col'>Contact Person</th>";

    echo "</tr>";

    $result = mysql_query("SELECT * FROM ops_supplier_tbl ORDER BY name ASC");
while($row = mysql_fetch_array($result))
  {
    echo "<tr align='center'>";
      echo "<td>".$row['name']."</td>";
      echo "<td>".$row['address']."</td>";
      echo "<td>".$row['contact_person']."</td>";

      echo "<td>".$row['fax']."</td>";
      echo "<td>".$row['email']."</td>";
      echo "<td><form name='' method='post' action='sup_select.php'><input name='supcheck[]' type='checkbox' value='".$row['name']."'></td>";
    echo "</tr>"; 
    }
    if(isset($_POST["supcheck"])) 
      {
          $checked = $_POST["supcheck"];
        } 
        else 
        {
            $checked=array();
        } 
        for ($i="0"; $i<count($checked); $i++) 
        { 
            if(!is_numeric($checked[$i])) 
            {
                $checked[$i]='';
            } 
            if(empty($checked[$i])) 
            {
            unset($checked[$i]);
            }
        }
        $checked=implode('<>',$checked);
echo "<input type='text' name='textfield' id='textfield' value='".$checked."'>"; 
echo "</table>";
    echo "<input align='left' type='submit'></form>";   
    echo "</form>";


 echo "</div>";
  ?>
</body>
</html>

我甚至尝试在同一页面上进行此操作，但它也不起作用。

Answer 1

所有supcheck[]应该是内部相同<form>。

supplier.php

需要进行一些更改

<form action='sup_select.php'>
    <table>
        ...
        <input name='supcheck[]' type='checkbox' value='".$row['name']."'>
        ...
    </table>
</form>

您可以使用以下方法在PHP中访问POST数据：

<?php var_dump($_POST['supcheck']); ?>

如果您需要在<TD>中指定<table>的按钮，则可以使用带有Javascript OnClick功能的按钮来触发另一个外部表单。

...
<td><input type='button' onclick='gotoReview(<? echo $supplier_id; ?>)' value='Review'></td>
...
<script>
    function gotoReview(id){
        location.href = 'supply_review.php?id=' + id;
    }
</script>

将页面中的多个复选框值获取到不同页面中的文本框
