将表单值附加到已包含变量的 URL

发布于 2024-12-12 01:23:14 字数 960 浏览 0 评论 0原文

我有一个页面显示用 PHP 编写的 MYSQL 查询的结果。 URL 包含用户在上一页提交的变量，如下所示：

www.mydomain.com/search/?var1=xx&var2=xx&var3=xx

当用户位于结果页面时，他们需要能够进行排序结果。为此，我有一个 SELECT 表单

<form action="/search<?php echo $urlQuery; ?>"  name="order "class="formsrch" method="post" >
            <label>sort by:</label>
            <select class="order" id="order" name="order" onChange="this.form.submit()">
                <option value="pricedesc">Price High to Low</option>
                <option value="priceasc">Price Low to High</option>
                <option value="dist">Distance</option>
            </select>
        </form>

变量 $urlQuery 包含要附加到 url 上的字符串：即 $urlQuery = "?var1=xx&var2=xx&var3=xx"

问题是，提交表单时，页面会重新加载，并且 url 末尾是 ?order=dist。

有没有办法用 & 符号替换问号，以便加载页面并检索 order 的值？

或者，如果有人有更好的方法来完成整个事情，我绝对愿意接受建议。谢谢

I've got a page showing the results of a MYSQL query written in PHP. The URL has the variables that the user submitted on the previous page as:

www.mydomain.com/search/?var1=xx&var2=xx&var3=xx

When the user is on the results page they need to be able to sort the results. To do this I've got a SELECT form

<form action="/search<?php echo $urlQuery; ?>"  name="order "class="formsrch" method="post" >
            <label>sort by:</label>
            <select class="order" id="order" name="order" onChange="this.form.submit()">
                <option value="pricedesc">Price High to Low</option>
                <option value="priceasc">Price Low to High</option>
                <option value="dist">Distance</option>
            </select>
        </form>

The variable $urlQuery contains the string to be appended onto the url:
i.e. $urlQuery = "?var1=xx&var2=xx&var3=xx"

The problem is that when the form is submitted the page is reloaded and at the end of the url is ?order=dist.

Is there a way of replacing the question mark with an ampersand so the page will load and the value of order can be retreived?

Or, if anyone has a better way of doing the whole thing I'm definitely open to suggestions.
Thanks

你为什么不把它们放在隐藏的形式中呢？

<?php
$extraVars = "";
  foreach($_GET AS $key=>$value) {
   $extraVars .= '<input type="hidden" name="'.$key.'" value="'.$value.'" />';
  }
?>
<form action="/search"  name="order "class="formsrch" method="post" >
    <?php echo $extraVars;?>
    <label>sort by:</label>
    <select class="order" id="order" name="order" onChange="this.form.submit()">
        <option value="pricedesc">Price High to Low</option>
        <option value="priceasc">Price Low to High</option>
        <option value="dist">Distance</option>
    </select>
</form>

why don't you put them in the form as hidden?

<?php
$extraVars = "";
  foreach($_GET AS $key=>$value) {
   $extraVars .= '<input type="hidden" name="'.$key.'" value="'.$value.'" />';
  }
?>
<form action="/search"  name="order "class="formsrch" method="post" >
    <?php echo $extraVars;?>
    <label>sort by:</label>
    <select class="order" id="order" name="order" onChange="this.form.submit()">
        <option value="pricedesc">Price High to Low</option>
        <option value="priceasc">Price Low to High</option>
        <option value="dist">Distance</option>
    </select>
</form>
