forms with dynamic inputs

[WindAndWaves]

Hi Gurus

I have a php page with a form in it, that is along the lines of:

<form...>
item with id 234
<input type=submit ... NAME=add234 ID=add234>
<input type=hidden NAME=add234 ID=234>
item with id 235
<input type=submit ... NAME=add235 ID=add235>
<input type=hidden NAME=add235 ID=235>
[....etc....]
</form>

In the PHP code at the top of the document, I want to:

a. intercept any submit from the form
b. get the related ID number

At the moment, I have only one add button, so I use code like this:

if($HTTP_POST_V ARS[add]){
...
.....
}

So my questions are:

A. how can I change

if($HTTP_POST_V ARS[add]){

to make it intercept any submit button that starts with add

B. how can I get the corresponding ID number


TIA

You can't get at the element id from within PHP, as that lives in the
client. Instead, give the submit buttons the same name (e.g.,
"submitted_ id") but a unique value. Then when any submit button is
clicked, the common name will have the unique value:

item with id 234
<input type='submit' ... name='submitted _id' value='add234'>
item with id 235
<input type='submit' ... name='submitted _id' value='add235'>
item with id 236
<input type='submit' ... name='submitted _id' value='add236'>


Then in your code:

$item_id = $HTTP_POST_VARS['submitted_id'];

$item_id will be one of 'add234', 'add235', or 'add236'.

Thank you for your reply. That is simpler than I thought. The only problem
I have now is that I don't want the text "add..." to appear on page. All I
want the user to see is "add to basket"....

Do you have any hints on this?

Whoops! I forgot that the value appears on the button. Instead of
using <input type="submit" ...>, use a <button> like this:

<button type="submit" name="submitted _id" value="add234"> BUTTON
TEXT</button>

You could even drop the "add" from the value so that you just get the
number back.

(I'm sleepy...) I guess that should have been:

<button type="submit" name="submitted _id" value="234">Add To Basket
</button>

Hi NM

I have the following:

<BUTTON TYPE="submit" NAME="add" VALUE="14" ID="add14" CLASS="addtotri p">add
to trip</BUTTON>

but it tells me that the value of the add button is "add to trip" and not
14, as I would have liked ....

what am I doing wrong?

Replace this:

ID="add14"

with this:

VALUE="add14"

Stay clear of the <button> element!

IE has a bad implementation in which the name / value pairs of ALL
<button> elements within the form are submitted - not just the one that
was clicked.

Use submit buttons with name of add_{$id}. Simply grep (ie run a regex
on) all the form values submitted for "add_\d+" (assuming that all IDs are
numeric).

I actually discovered that if I do not make it input type="submit" that I
run into other difficulties: the data is not really reposted and the old
data is kept instead. IN that way the user can only add the first product.

Well, anyway, let me knows

THANKS a lot for your help.

Could you translate that to novice PHP, sorry, but this is my very first
site that I have taken over from someone, and it is all a bit new to me.

I have changed it back to a submit button, I can add the
name="'.$rowIdn umber.'", but the rest I don't understand at all - lol

I just put the following onto a test page:

<form action="" method="get">
<BUTTON TYPE="submit" NAME="add" VALUE="14" ID="add14"
CLASS="addtotri p">add to trip</BUTTON>
<BUTTON TYPE="submit" NAME="add" VALUE="15" ID="add15"
CLASS="addtotri p">add to trip</BUTTON>
</form>

And when I press the first button the URL changes to this:

http://localhost/test/?add=14

and when I press the second button I get this:

http://localhost/test/?add=15

So the correct value is being returned. How are you extracting the
value in your PHP code?

This is all really:

<?php
session_start() ;

// Initialize variables
$errormessage = "";
$sqlStart = "SELECT a.id, a.FN, a.name, a.description, a.photolink,
a.regionId FROM friars a, regions b";
$sqlWhere = " WHERE (a.regionId = b.id) AND ";
$sqlEnd = " GROUP BY a.regionId, a.name ";
$humanSQL = "<UL>";
$maxrows = 50;

// If no sortorder is set, initialize it to 1
if(!$sortorder) {
$_SESSION["sortorder"] = 1;
}


//If an Accommodation is to be added
if($HTTP_POST_V ARS[add]){

// Add accomodation to the session with an incremented sortorder
$_SESSION["sortorder"] = $sortorder + 1;

$id = 0;
$id = $HTTP_POST_VARS['add'];
echo '************** *** ID = '.$id;

// Select DB data for accommodation to ADD and Append to Session
include_once("c onnectDB.php");
$sqladd = "SELECT * FROM friars WHERE id = $id";
$resultAdd = mysql_query($sq ladd);
$myrowAdd = mysql_fetch_arr ay($resultAdd);

.....lots of other code

Looks like that should work to me. I just read La'ie Techie's post.
Are you using IE? I'm using FireFox.
