如何将select选项中的值传递给其他形式的其他选择选项

问题描述：

I want to move data from one form to another form with similar inputs in diferent pages, as I do to make the select option to acquire the same value when I submit form1 and form2 sees.

<form action="form2.html" method="post">
<select name="selection" >
  <option value="" selected="selected">select one</option>
  <option value="1" >one</option>
  <option value="2" >two</option>
  <option value="3" >three</option>
</select>

i need to get this value in the second form "form2.html"

how i can do this?

thanks !!

我想将数据从一个表单移动到另一个表单，在不同的页面中使用类似的输入，就像我做的那样当我提交form1和form2看到时，选择选项以获取相同的值。 p>

 ＆lt; form action =“form2.html”method =“post”＆gt; 
＆lt; select  name =“selection”＆gt; 
＆lt; option value =“”selected =“selected”＆gt;选择一个＆lt; / option＆gt; 
＆lt; option value =“1”＆gt; one＆lt; / option＆gt; 
＆lt;  option value =“2”＆gt; two＆lt; / option＆gt; 
＆lt; option value =“3”＆gt; three＆lt; / option＆gt; 
＆lt; / select＆gt; 
  code>  pre> 
 
  我需要以第二种形式“form2.html”获取此值 p> 
 
 
我该怎么做？ p> 
 
 
谢谢!!

答

The action page is necessarily a server page. You have to set the second page say, as form2.php. The data you submit here will go to the form2.php as a post value. It will be something like this :

<form action="form_submit.php" method="post">
<select name="selection2" >

 <option value="1" <?php if($_POST['selection'] =="1"){echo "selected='selected'";}?> >one</option>
 <option value="2" <?php if($_POST['selection'] =="2"){echo "selected='selected'";}?>>two</option>
 <option value="3" <?php if($_POST['selection'] =="3"){echo "selected='selected'";}?>>three</option>
</select>
</form>

Thus you can get the value in the previous value selected in your new form. Otherwise you may use session to store the value temporarily.

There is not a trivial answer, you could set a $_SESSION variable, save in cookie, save in database and then SELECT that data on the next page using the appropriate method.
