Question

我需要将大量结果传回一个表单，以便表单可以从URL中读取这些结果，然后用它们填充表单。问题是，链接最终是：

＆amp; key = value＆amp; key = value ...直到它不能再处理（我假设一个URL有长度限制？）导致我的表单无法完全填充。我需要另一种方法将值传递回我的表单文件。

VIEW.php文件（基本上只是一个值表，因为它们来自数据库，第一列＆＃34; id＆＃34;是一个链接。当我点击＆＃34; id＆＃34; ，它会回到我的add.php（表单页面）并使用匹配该id的数据填充表单。

<table border="0" cellpadding="0" cellspacing="0" id="table">
            <thead>
                <tr>
                    <th>ID</th>

                    <th>DESCRIPTION</th>

ADD.php（表单页面，表单应该获取数据并填充它）

        if (form_validity() == 1)

            // connect to mysql + database

            $saleItem = "n";
            $discountItem = "n";

Answer 1

使用method="post"和$_POST（而不是$_GET）。

POST请求可能比GET请求大得多，因为GET请求受URL的最大长度限制。 POST请求受max_post_size ini-value的大小限制，通常为几兆字节。
