[PHP] Arrays and Forms
Hello Everyone, I'm having trouble sending array values through forms. Will the following syntax create a variable called $product['desc'] on the next page? If not, what am I doing wrong here? Note: I tried this but it didn't work! When I tried doing it without using an array, but rather with a regular variable, it sent through just fine and created a variable of the name attribute in the input tag. menu_add.php - form method=post action=menu_list.php input type=text name=product[desc] /form menu_list.php - echo $product['desc']; Result output - no output -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Arrays and Forms
Try:
input type=text name=product[]
?
foreach ($product as $p) {
print $p;
}
?

Re: [PHP] Arrays and Forms
Your code looks fine. Are you sure you haven't edited away significant parts of it when posting to the list? Maybe a input name=product somewhere? miguel On Sun, 19 May 2002, Navid Y. wrote: I'm having trouble sending array values through forms.

Re: [PHP] Arrays in forms {?!}
1) The example you have shown should work. Take a look at the foreach controle
structure. (Link at bottom of mail.)
2) You cannot assign a value to a checkbox. It can only be set by the checked
keyword (ie: input type=checkbox name=foo checked.)
3) The value of a checked checkbox is on. If a checkbox is not checked it will not
be passed to you by the clients browser. So if you where wondering why you could not
get the value of some of the checkboxes, then that was why.
4) If you don't have to give the user a more thorough description then why not make a
multiselect select box instead.
Example on a multiselect selectedbox
select name=foo[] size=20 multiple
option value=bar1desc/option
option value=bar2 selecteddesc/option
...
/select
The above selectbox will display 20 rows in the box and if there is more than 20
selections you will be able to scroll it.
You can get more information at:

Hi all,
I have a form, with about 40 checkboxes, I want to write a PHP document
that
processes the submission and displays the values of the checkboxes that
were
checked.
Pretty basic stuff, I've tried a few different things, some work but
display
Array at the top of the list of values.
Snippet of HTML
td
input type=checkbox name=games[] value=Counter-Strike
/td
tdCounter-Strike/td
td
input type=checkbox name=games[] value=Total Annihilation
/td
tdTotal Annihilation/td
/tr
/Snippet of HTML
Snippet of PHP
while ( $element = each( $games ) )
{
echo $element[value];
echo br;
}
/Snippet of PHP
I tried this too, it gave the same results as the above...
if (is_array($games)) {
for ($z=0;$zcount($games);$z++) {
echo $games[$z]BR;
}
}
else {
echo $games;
}
I'm missing something real stupid, please help me out
Thanks,
Liam

[PHP] arrays in forms.
Hi, I have a multi-select listbox set up like this:
Author (you are able to select more than one.a href=addauthor.phpClick
here to add a new author/a)br:
select name=author multiple size=5
?php
$result = mysql_query(SELECT AUTHOR_ID, AUTHOR_FNAME, AUTHOR_LNAME FROM
AUTHORS;) or die(mysql_error());
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$option = option value= . $row[AUTHOR_ID] . .
$row[AUTHOR_FNAME] . . $row[AUTHOR_LNAME] . /option;
echo $option;
}
?
/selectbr
I then have a bit of code that parses through and checks which authors they
selected, if any.
if isset($author) {
if is_array($author) {
foreach($authors as $key=$value) {
$query = INSERT INTO BYLINE(TITLE_ID, AUTHOR_ID)
VALUES( . $titleid . , . $value . );;
mysql_auery($query) or die(echo mysql_error());
}
} else {
$query = INSERT INTO BYLINE(TITLE_ID, AUTHOR_ID) VALUES(
. $titleid . , . $author . );;
mysql_auery($query) or die(echo mysql_error());
}
}
What I'd like to know is, is this correct, incorrect, redundant, etc?

[PHP] Arrays from forms
Can someone please help me with this code I'm having major problems with
arrays. This code is part of a function I'm writing to deal with an array
returned from a HTML form of check boxes so if anyone has an example of this
sort of thing I'd appreciate a look at it. Anyway Code follows :
//Reading from a data base
$db = mysql_connect("$DB_Server", "$DB_Login, $DB_Password");
mysql_select_db("$DB_Name",$db);
$results = mysql_query("SELECT option_type, code FROM options WHERE
code='000' ORDER BY option_type",$db);
mysql_fetch_array($results);
// From what understand I should have an array some thig like this:
// ("Size"="A4" , "Size" = "A3", "Size"="A5", "Colour"="Red", etc..);
$types = array_values($results);
// OK so now I think I have an array like this:
// ("A4" , "A3", "A5", "Red", etc..);
while ($type =array_pop($types)){
echo $type."br";
}
// Now I'm expecting this list to be printed to be outputted
A4
A5
A3
Red
etc...
I'm figureing that this would be a good way to retreive a listing from the
web site arrays and test and insert them one by one.
/// The table options
option_type || code || option_preferences
Size || 000 || A4
Size || 000 || A3
Size || 000 || A5
Colour || 000 || Red
Colour || 000 || Blue
Colour || 000 || Green

According to your SQL statement that doesn't appear to be true. According
to your SQL statement you'll return two fields: option_type and code.
$types = array_values($results);
// OK so now I think I have an array like this:
// ("A4" , "A3", "A5", "Red", etc..);
while ($type =array_pop($types)){
echo $type."br";
}
I'd avoid using array_values() and array_pop(). Simply do this:
while ( $row = mysql_fetch_array( $result ) )
{
$option_type = $row[option_type];
$code = $row[code];
echo "$option_type $codebr";
}
Hopefully that'll be enough to get you going.
