需要有关通过带有 select 框的表单提交值的帮助吗？

Question

I have a empty select box on a form.

<select id='essentialDocs[]' ></select>

through some script i add options to it. Basically it adds URL's. So at runtime html will look like

<select id='essentialDocs[]' >
<option value='http://www.google.com' title='Google'>Google</option> 
<option value='http://www.yahoo.com' title='yahoo'>Yahoo</option>
</select>

Now on submitting the form i want to get both of these key:value pairs

like Title:URL google:http://www.google.com

but on doing $_POST['essentialDocs'] i only get values and not title's. What modification would help get me both. Also another thing i have on the form is i can switch the ordering of url's on screen. Please suggest some solution

Answer 1

If you need the title map the title to the URL on the server in eg A dictionary or array .

IMHO it would be even better to do it the other way around. Set the title as a value and map it to a URL on the server.

  $arr["Google"] ='http://www.google.com'
  $arr["yahoo"] = 'http://www.yahoo.com' 

then you also have the ability to maintain this array on the server and echo it (back) into the select.

Try this. This may help you..

Just add title in value with: When you submit you get your desire value.

<form method="post" action="">
  <select id='essentialDocs[]' name='list'>
    <option value='google:http://www.google.com' title='Google'>Google</option> 
    <option value='yahoo:http://www.yahoo.com' title='yahoo'>Yahoo</option>
  </select>
  <input type="submit" name="Submit" value="submit">
</form>

Print post array in PHP

<?php 
  print_r($_POST);
?>

Output:

Array ( [list] => yahoo:http://www.yahoo.com [Submit] => submit ) 

Now you can get both title and URL.
