[PHP] How to post unknown amount of data ?
Hello all,
I'm having a trouble. I'm programming an CMS
for one pc company. So in example i'm doing
a pc category catalog admin. They can add/delete/modify
theese category's. But also they want one feature:
they want to edit all category's in one form.
So i made a form that displays all category's in
input type=text so they can edit, but
the problem is that i dunno how many there will
be category's and how to organize data passing to
script. User submits form with all changes,
and my script needs to get all theese category's
with id's and changed names.
Ok how it looks in script:
Function display_all() {
Print form action='category.php' method='post' name='editcat'
INPUT TYPE=hidden NAME='admin_editall' VALUE='1';
$result=mysql_query(SELECT cat_id,
cat_name,
cat_show
FROM cat
GROUP BY cat_id ASC);
While ($row=mysql_fetch_array($result)) {
$cat_id=$row[cat_id];
$cat_name=$row[cat_name];
$cat_show=$row[cat_show];
Print tr class=tb1tdinput type='text' name='cat_id'
size='2' maxlength='4' value='$cat_id'
disabled/td\n;
Print tdinput type='text' name='cat_name$cat_id'
size='50' maxlength='50' value='$cat_name'/td
tdinput type='checkbox' name='cat_status';
if ($cat_show==Y) {Print checked;}
Print /td/tr\n;
}
}
// ^^^ this form post all data into same file category.php
//and function add_all_db() must get all data.
Function add_all_db(){
?
// here i must add theese changes to db
// i know how to add to db, but dunno
// how to get forms passed data.
}
PHP Version 4.0.4pl1
MySQL Version 3.22.30
Thank u for your help.

Re: [PHP] How to post unknown amount of data ?
The best way of doing this is to name the fields catid[]
The [] means that they are inserted into an array in the order they appear
on the page, so on the page with deals results you just have to cycle
through the array.
As a side point, there is no way of telling what has been modified and what
is not (well without comparing the variables to the db again).. so it is
usually quicker just to update the whole.lot.
HTH, Tom

RE: [PHP] How to post unknown amount of data ?
You can enumerate the form vars for example
if you have an unkown amount of comments
for($i=0;$isizeof($comments);$i++) {
echo input type=text name=commentid$i;
}
etc

(sorry I'm not going to look at your code, better split HTML creation
and data(-retrieval))

RE: [PHP] How to post unknown amount of data ?
forgot something
to enumerate them in your script use something like
for ($i=0;$isizeof($comments);$i++) {
$cmt = $HTTP_FORM_VARS[commentid . $i];
}
