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? 我的朋友告诉我,我应该使用“post method”,但我不知道该怎么做 将它应用于我的代码......
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;
?>

你需要在index.php中添加以下内容,当这个表单提交时,它将重定向到产品页面,你将获得你的价值
<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> </td>
</tr>
<tr>
<td><input type="submit" name="submit" id="submit" value="Add to Cart" /></td>
</tr>
<tr>
<td> </td>
</tr>
</table></td>
<td width="299"><?php echo $row_productinfo['description']; ?></td>
</tr>
</table>
</div>
</form>
在productinfo.php中你需要添加
<?php if(isset($_POST['submit'])):
echo $name=$_POST['product_name'];
echo $brand=$_POST['product_brand'];
echo $category=$_POST['product_category'];
echo $price=$_POST['product_price'];
endif;
?>
在此页面上使用此变量
答案 1 :(得分:0)
您的表单没有任何字段。
1)在index.php中执行以下更改:
<tr>
<td><input name="name" type="text" value="<?php echo $row_showproduct['name']; ?>" /></td>
</tr>
<tr>
<td><input name="brand" type="text" value="<?php echo $row_showproduct['brand']; ?>" /></td>
</tr>
<tr>
<td><input name="category" type="text" value="<?php echo $row_showproduct['category']; ?>" /></td>
</tr>
<tr>
<td><input name="price" type="text" value="<?php echo $row_showproduct['price']; ?>" /></td>
</tr>
2)确保productinfo.php对数据做了些什么。使用:print_r($ _ POST)来检查发布数据。
不要使用mysql_ *函数。从PHP 5.5开始,它们已被弃用,并在PHP 7中被删除.Insead使用:http://php.net/manual/en/book.mysqli.php
答案 2 :(得分:0)
是的,您的朋友告诉您是对的,您可以使用帖子将数据从一个页面传递到另一个页面。
您可以通过四种方式将数据从一个页面传递到另一个页面。
1.使用表格
您需要感受表单中的数据并提交您重定向到另一个页面的表单(在表单的操作属性中定义)并在rdirected页面中检索数据
让我们举个例子 的的index.php 强>
<form action="production.php" method="post">
<input type="text" name="txt_name">
<input type="submit" value="Submit" name="product">
</form>
production.php
<?php
// on submit button is clicked
if(isset($_POST['product'])){
if(isset($_POST['txt_name']) && $_POST['txt_name'] != ""){
$name = $_POST['txt_name'];
}
}
?>
上面的代码是检查提交按钮,如果单击则单击,而不是设置输入文本的值,如果设置的话,它不是空白而不是检索名称
这里我们使用$_POST
表单的coz方法设置“post”默认方法是“get”。如果你没有定义任何方法而不是设置默认方法get。因此您可以使用$_GET
无论使用$_REQUEST
2.使用Anchor
3.使用会话
4.使用Cookie
答案 3 :(得分:-2)
首先,当用户在表格中选择一行时,您必须创建一些字段并通过javascript将其设置为val。在此之后,您可以通过$ _POST ['name_of_field_in_index.php']获取productinfo.php中的信息。
