php - 在我的代码中使用 Post 方法

标签 php html

你能帮我解决这个问题吗？

如何将我从 Index.php 中选择的信息传递给 productinfo.php？ 我的 friend 告诉我，我应该使用“post 方法”，但我不知道该怎么做 将其应用于我的代码...

这是我的代码

index.php:

<?php require_once('Connections/localhost.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

$maxRows_showproduct = 6;
$pageNum_showproduct = 0;
if (isset($_GET['pageNum_showproduct'])) {
  $pageNum_showproduct = $_GET['pageNum_showproduct'];
}
$startRow_showproduct = $pageNum_showproduct * $maxRows_showproduct;

mysql_select_db($database_localhost, $localhost);
$query_showproduct = "SELECT * FROM product";
$query_limit_showproduct = sprintf("%s LIMIT %d, %d", $query_showproduct,  $startRow_showproduct, $maxRows_showproduct);
$showproduct = mysql_query($query_limit_showproduct, $localhost) or die(mysql_error());
$row_showproduct = mysql_fetch_assoc($showproduct);

if (isset($_GET['totalRows_showproduct'])) {
  $totalRows_showproduct = $_GET['totalRows_showproduct'];
} else {
  $all_showproduct = mysql_query($query_showproduct);
  $totalRows_showproduct = mysql_num_rows($all_showproduct);
}
$totalPages_showproduct =     ceil($totalRows_showproduct/$maxRows_showproduct)-1;
?>

最佳答案

you need to add from as below in index.php when this form submit it will redirect to product page and you will get your value

<form id="productform" name="productform.php" action="productform.php" method="post">
          <div id="itemimg">1</div>
            <div id="itemdesc"><br />
              <br />
              <table width="600" border="0" cellspacing="0" cellpadding="0">
                <tr>
                  <td width="301"><table width="300" border="0" cellspacing="0" cellpadding="0">
                    <tr>
                      <td><?php echo $row_productinfo['name']; ?>
                      <input type="hidden" value="<?php echo $row_productinfo['name']; ?>" name="product_name"></td>
                    </tr>
                    <tr>
                      <td><?php echo $row_productinfo['brand']; ?>
                      <input type="hidden" value="<?php echo $row_productinfo['brand']; ?>" name="product_brand">
                      </td>
                    </tr>
                    <tr>
                      <td><?php echo $row_productinfo['category']; ?>
                      <input type="hidden" value="<?php echo $row_productinfo['category']; ?>" name="product_category">
                      </td>
                    </tr>
                    <tr>
                      <td><?php echo $row_productinfo['price']; ?>
                      <input type="hidden" value="<?php echo $row_productinfo['price']; ?>" name="product_price">
                      </td>
                    </tr>
                    <tr>
                      <td>&nbsp;</td>
                    </tr>
                    <tr>
                      <td><input type="submit" name="submit" id="submit" value="Add to Cart" /></td>
                    </tr>
                    <tr>
                      <td>&nbsp;</td>
                    </tr>
                  </table></td>
                  <td width="299"><?php echo $row_productinfo['description']; ?></td>
                </tr>
              </table>
            </div>


        </form>

and in productinfo.php you need to add

    <?php  if(isset($_POST['submit'])):
        echo $name=$_POST['product_name'];
        echo $brand=$_POST['product_brand'];
       echo  $category=$_POST['product_category'];
       echo  $price=$_POST['product_price'];
endif;
        ?>

use this variable where you need on this page
