PHP标题添加多次

我有这个问题:

$get_ids = "SELECT unique_id FROM products GROUP BY unique_id LIMIT 10";
$id_results = mysql_query($get_ids);
while($id_row = mysql_fetch_array($id_results))
{
    extract($id_row);
    $all_prods_link[] = $id_row['unique_id']; 
}

这将创建一个整数数组。对于数组中的每个项目,我将其附加到一个字符串,后面跟一个逗号:

foreach($all_prods_link as $all_prods)
{
    $query_string .= $all_prods.',';
}

结果如下:1,2,3,4,5,6,按预期工作。

我遇到的问题是我试图将其添加到当前URI的末尾,然后重定向到此URI,例如:

$link = $_SERVER['REQUEST_URI'] . '&product_options=' . $query_string;

$ link变量看起来不错:

sales_reports.php?date_from=05%2F11%2F2017&date_to=05%2F12%2F2017&pay_status=Paid&submitfilter=Go&prodtype=all&report_type=productreports&product_options=1,2,3,4,5,6,7,8,9,10,

这正是我想要的,但是当我尝试重定向到此链接时,例如:

header("Location: $link");

我最终得到的实际URI有$ query_string,多次附加到它上面,如下所示:

sales_reports.php?date_from=05%2F11%2F2017&date_to=05%2F12%2F2017&pay_status=Paid&submitfilter=Go&prodtype=all&report_type=productreports&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,&product_options=1,2,3,4,5,6,7,8,9,10,

如您所见,"& product_options"出现多次,然后是整数列表!

header()函数可以这样使用吗?或者我在做一些可怕的错误!

1 个答案:

答案 0 :(得分:1)

这是因为每次加载页面时都会有多次重定向,php会追加 product_options而不是替换它。

<?php

// Parse all request components
$request = parse_url($_SERVER['REQUEST_URI']);

// Parse incoming query sting to array
parse_str($request['query'], $queryArray);

// replace or add product_options
$queryArray['product_options'] = $query_string;

// rebuild the query
$newQueryString = http_build_query($queryArray);

$link = $request['path']. '?' . $newQueryString;

header("Location: $link");
