passing on fields using PHP

amarafzal

Ive got a form that has 2 drop down lists. What im trying to do is pass on what the user selects to another page, which should pass on what they selected to another until finally the details selected are posted using php email.

But how do i pass on what they select and store it until i finally need to use it?

Help me please!!!!!

the simplest way is to use sessions. take a look at:
http://www.php.net/manual/de/ref.session.php

if you only have to store these to values, it would also be possible to keep them in a hidden form field. i.e.:
Page1 > dropdown_1, dropdown_2
SUBMIT FORM
Page2 > store $POST['dropdown_1] & $POST['dropdown_2] in hidden fields
SUBMIT FORM
Page3 > do whatever you want with $POST['dropdown_1] & $POST['dropdown_2]

Use hidden fields. When you post to another page which has a form, put the previous input fields as a hidden filds inside the form.

Other way is to use sessions put it doesnt work if some poor chap has disabled cookies..

Example.

form1.php

<form method="post" action="form2.php">
<input type="text" name="something">
</form>

form2.php

<form method="post" action="form3.php">
<input type="hidden" name="something" value="<?=$_POST['something']?>">
<input type="text" name="something_else">
</form>

And so on.. You get the picture?

sessions will work even without activated cookies... there is an option in the php.ini which allows to add the session-id to every link if someone has cookies disabled... seems to work quite good

True, but most webservers have safe mode set to 'on' and therefore cant change the php.ini...

trexx

also true ... but some have their own webserver 😉

i put the above in to the page after the user chooses the fields, this page then goes to to page which generates an email, when i recieve the email, the values selected do not appear.

any reason why?

BTW thanks for all the replys

it should look like:

<input name="region" type="hidden" id="region" value="<?=$_POST['region']?>">
