[RESOLVED] PHP, form and variables

sebjlan

Hi,

I need a little help building a PHP script.

I'm not sure how to explain this, so I hope you will understand anyway 🙂

When a user is forwarded to a specified page, for instance to http://www.mydomain.com/form.php?name=john?surname=williams from a form, I want to have two values assigned to the name-querystring.

With name, there should be a full name and an ID assigned, and with surname only a name is needed, so that will be:

$surname = $_GET['surname'];

But I need help with the name-querystring with two values. (Both a name and an ID number should be assigned to $_GET['name'];)

I then want this information to be displayed on the current page. In the above example it should say

Name: John Williams
ID: 1234

Just decide how you want the info separated. There are a couple options:

|

_
+
XxX

it can be anything, as long as it's consistent. So the name would become:

$_GET['name'] = 'John|1234';
$_GET['surname'] = 'Williams';

How would I then call the ID?

list($name, $id) = explode('|', $_GET['name']);

An easier and simpler way is to

$name = $GET['name'];
$id = $GET['id'];

and retrieve these from the querystring.

I know, but I want to avoid that.

I want to create some name-variables with IDs assigned to them, so when the URL says http://www.mydomain.com/form.php?name=john&surname=williams, the $id should be 1234.

This does not seem to work:

if (isset($_GET['name'])) {
$_GET['name'] = array('john|1234', 'julie|1235');
list($name, $id) = explode('|', $_GET['name']);
}

umm... because you're exploding an array.. can't do that.... if you want to do that, you'd need to itterate through the array:

<?php
if(isset($_GET['name']))
{
  $_GET['name'] = array('john|1234', 'julie|1235');
  foreach($_GET['name'] as $unknown)
  {
    list($name, $id) = explode('|', $unknown)
  }
}

Thanks 😉
