Saving the value from a drop-down list

phphtmlvariablesdrop-down-menu

提问by DogPooOnYourShoe

Here's my situation, I have 2 pages, one for selecting a value and one for editing database related things which are associated to that value.

这是我的情况,我有 2 页,一页用于选择值,另一页用于编辑与该值关联的数据库相关内容。

Right now, I have no knowledge ( and have researched a fair bit ) on how to save the value selected from the drop down list into a variable from PHP.

现在,我对如何将从下拉列表中选择的值保存到 PHP 的变量一无所知(并且已经研究了一些)。

Any ideas?

有任何想法吗?

Its two step: First html:

它的两个步骤:首先是 html:

<form action='databasethings.php' method=post>
<select name="myvalue">
  <option value="value1">Value 1</option>
  <option value="value2">Value 2</option>
  <option value="value3">Value 3</option>
</select>
<input type=submit>
</form>

Its for sending the value to databasethings.php script.(

它用于将值发送到 databasethings.php 脚本。(

Then in databasethings.php:

然后在databasethings.php中:

$myvalue=$_POST['myvalue'];
//do something with myvalue

This will catch value1, 2 or 3 from html into $myvalue in php

这会将 html 中的 value1、2 或 3 捕获到 php 中的 $myvalue

I presume you are submitting a form to the page for editing database related things. On that page use $_REQUEST['the_name_of_the_select_box']

我假设您正在向页面提交表单以编辑与数据库相关的内容。在该页面上使用 $_REQUEST['the_name_of_the_select_box']

    <select name="the_name_of_the_select_box"> 

the select value will be in

选择值将在

    $_REQUEST['the_name_of_the_select_box'] or  $_POST['the_name_of_the_select_box']
