This question is probably more appropriate for a JS list... but I'm not mean,
so I'll let you know. The easiest way would be to update the blur event qty
input:
onblur=calculateBidUnit(this.value);
Now you have the value sent to that function. Another way would be to give your
input and output an id each - let's say 'qty' and 'bid_unit_value',
respectively. Then reference those ids in your function. This gives you the
following:
input type=text name=qty[] value=!!quantity!!
onblur=calculateBidUnit(); id=qty /
input type=text name=bid_unit_value[] value= id=bid_unit_value /
script type=text/javascript
function calculateBidUnit () {
var qty = document.getElementById('qty');
var buv = document.getElementById('bid_unit_value');
buv.value = qty.value;
}
/script
I'll give you a small warning. All browsers are not alike, so my recommendation
would be to use a library that handles the cross-browser compatibility portion
of javascript (I use Mootools). Nonetheless, the above *should* work. Learning
the bare bones of javascript will help with the more complicated stuff and
you'll be smarter for it! =P

Hey Philip,
But will that ID value identify the right member of each

Each text input will only contain 1 value... and contain 1 unique id. So, if
you have multiple input boxes with the same name (qty[]), only the $_POST
output will contain an array of each value. See below...
input type=text name=qty[] value=1 id=qty1 onblur=calc(this.value);
/
input type=text name=qty[] value=2 id=qty2 onblur=calc(this.value);
/
input type=text name=qty[] value=3 id=qty3 onblur=calc(this.value);
/
input type=text name=bid_unit_value[] value= id=buv /
script type=text/javascript
function calc (value) {
document.getElementById('buv').value = value;
}
/script
When you blur qty1, buv will receive the value 1; blur qty2, buv will be 2; and
so on. The last input box that you blur on will determine buv's final value
(unless you throw in some logic to handle this)...
script type=text/javascript
function calc (value) {
var buv = document.getElementById('buv');
if (buv.value == '') buv.value = value;
}
/script
So, let's say you blur on qty2 and then submit the form, your PHP script will
have this in $_POST...
Array
(
[qty] = Array
(
[0] = 1
[1] = 2
[3] = 3
)
[bid_unit_value] = Array
(
[0] = 2
)
)
If this is not what you're wanting, you will need to modify the behavior above.
If you're wanting the bid_unit_value to contain all the values of each blur,
you may want to do something like this...
script type=text/javascript
function calc (value) {
var buv = document.getElementById('buv');
if (buv.value == '') buv.value = value;
else buv.value += '|'+value;
}
/script
Which may result from each blur in $_POST to be...
Array
(
[qty] = Array
(
[0] = 1
[1] = 2
[3] = 3
)
[bid_unit_value] = Array
(
[0] = 2|1|3
)
)
Or something along those lines. Then you can just explode() on that first index
to get individual values. Maybe you can clarify your ultimate goal and we can
assist you in what the best plan is.
Hope that helps,
~Philip

You'll just get Array back.
You can do a few things:
?php
foreach($attend_ary_save as $k1 = $v1){
foreach($v1 as $k2 = $v2){
?input type=hidden name=attend_ary_save[?php echo $k1?][?php

Actually, you should wrap htmlentities() around each value being echo-ed
out.
Another option is to http://php.net/serialize the data before you send it to
HTML, and then (duh) unserialize it when it comes back.
Or, be REALLY smart, and use session_start() and just put the array in
$_SESSION and don't send data back-n-forth over HTTP, which is A) expensive,
and B) subject to user tampering, and C) inefficient.
Actually, A and C technically depend on your bandwidth versus hard drive
speed, or wherever you store you session data, so, in theory, it could be
cheaper or more efficient to use HTTP... But I sure doubt it in any real
world hardware setup.
PS Just FYI, internally, PHP's session data is just serialized the same way
you'd do it for HTTP.

lose the fact that these are part of $keylist).

so that takes care of walking the array but now I need to protect myself

Re: [PHP] passing an array in a link
from my experience, you don't really have to worry much on the space issue. is the delimiter to determine that the string terminates and a new argument begins next. and very often, the browser will do an auto conversion from space to %20 when you click on the link.

Re: [PHP] Passing an array on
you can use serialize() and unserialize() and make sure that you urlencode() and urldecode() the serialized string before attaching it to your URL. if you don't, you might find that some chars will not be right on the other end of the line.

Re: [PHP] Passing an array as an argument
You can't put $a[][] inside a qouted string like that. Either use
${a[][]} or put it outside like this:
Print( option value=\.$aOptions[1][0].\.$aOptions[1][1].\n);

RE: [PHP] Passing an array to a C program from a php script??
Here is a solution I've found for my problem. I use join to convert my array
into a string. Then, I use exec to run the c program, having a pipe passing
the result from an echo. I would like to know if this solution is a good
one (in term of speed, security...), and would appreciate your comments.
Thanks.
Nicolas
Here is a short example :
// Initialize the array
$ary_test = array(15, 150, 32, 46, 69, 40, 22);
// Convert it to a string
$str_test = join(' ', $ary_test);
// Execute the c program
exec(echo \$str_test\ | test1, $ary_result, $num_return);
// Display the return value and the result of the program
echo Return value : $num_return\n;
echo Result :\n;
print_r($ary_result);

Objet : [PHP] Passing an array to a C program from a php script??
Hi all,
I have a big array (nearly 1000 lines) that I would like to pass to a C
program. I don't want to create a temporary file to pass my array (If
possible ?!?), and I don't think the command line will fit my needs.
Is there a way to execute a program with a php string as the standard
input. Something like shell redirection 'c_program input.file' but with
input.file being a php variable and not a real file ?? Any other solution
??
Hope I am clear enough !
Any help would be appreciated.

You may need to use PHP's http://php.net/serialize function to turn your array into a giant string and write a C routine to unserialize it, or, by the time you get done converting your program to PEAR, it will just accept your PHP array as an argument. #2 (pretty slick, though...) Run your C program using http://php.net/psockopen and use http://php.net/fputs to spew your data at it one line at a time. -- WARNING [EMAIL PROTECTED] address is an endangered species -- Use [EMAIL PROTECTED] Wanna help me out?

Just as any other variable. Read on...

mysql_select_db($database_mysql);
while (list ($key, $val) = each ($email)) {
echo "$key = $valbr";

process_members($asker_rank, $total_members, $email);
Look at the definition of process_members() again. The function takes two
values. The first is called $asker_rank and the second $email.
Now you pass *three* values to it. #1, $asker_rank, is fine. But #2,
$total_members, is passed in place of $email, so every time the function
body accedded its "$email" parameter, it gets the value of $total_members
- which is not an array.
The third parameter is ignored.

Re: [PHP] Passing an array as an argument.
Hi April,
I suggest you code your array into one string (it depends to the size)
then decode it at the other end using your own code. It's the easiest
trick to pass the array, compress it into one variable, then extract it at
the other end.
Any other ideas? ;-)

How do you pass an array as an argument to a function?
My code (or at least the important parts):
function process_members($asker_rank, $email) {
global $database_mysql;
mysql_select_db($database_mysql);
while (list ($key, $val) = each ($email)) {
echo "$key = $valbr";
}
}
# This will display fine. #
while (list ($key, $val) = each ($email)) {
echo "$key = $valbr";
}

RE: [PHP] Passing an array as an argument.
try:
function process_members($asker_rank, $total_members, $email=array()) {
global $database_mysql;
mysql_select_db($database_mysql);
while (list ($key, $val) = each ($email)) {
echo "$key = $valbr";
}
}
process_members($asker_rank, $total_members, $email);
Your original function declaration only has two variables passed to it. You
are passing three variables when you call the function.
What's happening is this:
function process_members($asker_rank, $email) {
global $database_mysql;
mysql_select_db($database_mysql);
while (list ($key, $val) = each ($email)) {
echo "$key = $valbr";
}
}
process_members($asker_rank, $total_members, $email);
step one:
php sets $asker_rank (in function declaration) equal to $asker_rank
step two:
php sets $email (in function declaration) equal to $total_members
step three:
php ignores $email array passed to process_members()
step four:
php passes $email to each(). $email is set to the value
of $total_members, which is not an array, and chokes.
Using :
function process_members($asker_rank, $total_members, $email=array())
{
...
}
allows you to have a default value for $email. So you can either pass it or
not.
