Re: [PHP] Nested foreach statement
It will probably work, and you could find out for sure by just trying it.
It might be better to construct a single query using things like:
$company_ids = implode(', ', $_POST['reporton_company']);
$query .= WHERE company_id IN ($company_ids) ;
This presumes you have already validated the company_ids.
However, if the number of companies, periods, and questions is SMALL,
the difference between one big query and a dozen little queries is
pretty minimal, and if you find the nested loops easier to maintain,
go for it.

Have been wondering if this is possible
Basically I have 3 posted arrays,
$_POST['reporton_company'] (this can be various company id's. ie
3,6,7)
$_POST['report_period'] (this can be various periods but a max of 4
submitted. ie 3,4,5)
$_POST['questions_groups'] (this can be various - starting from 1-
whatever
(usually a max of 10 or 11). ie 1,2,3,4,5,6,7,8,9,10)
So the select should work as
1. for each company listed go through the loop
2. for each report period listed go through loop for each company
3. for each questions group go through the loop for each report period
and
each company..
So I came up with this - will it work??
foreach($_POST['reporton_company'] as $cmp_ind =$arrayd_cmp_id) {
foreach($_POST['report_period'] as $rep_ind =$arrayd_per_id) {
foreach($_POST['questions_groups'] as $group_ind =
$arrayd_group_no) {
mysql_select_db($database_name, $dname);
$query_get_list_of_answers = SELECT * FROM answers
LEFT JOIN
(questions,
period) ON (questions.id=answers.ans_l_question_idAND
period.per_id=ans_l_period_id) where ans_l_company_id =
'$arrayd_cmp_id' AND
per_id = '$arrayd_per_id' AND group_no =
'$arrayd_group_no';;
$get_list_of_answers = mysql_query($query_get_list_of_answers,
$antiva) or
die(mysql_error());
$row_get_list_of_answers = mysql_fetch_assoc($get_list_of_answers);
$totalRows_get_list_of_answers = mysql_num_rows($get_list_of_answers);
}
}
}
Anyone suggest an easier way?

Why do that here? That's going to do it for each element in the
arrays, lots of overhead!
Move that outside the first loop.
I'd probably leave it as it is and make sure your data is what you
expect, ie use mysql_real_escape_string in appropriate places.
You could clean up one loop by doing this:
$query_get_list_of_answers = SELECT * FROM answers LEFT JOIN
(questions, period) ON (questions.id=answers.ans_l_question_id AND
period.per_id=ans_l_period_id) where ans_l_company_id =
'$arrayd_cmp_id' AND per_id = '$arrayd_per_id' AND group_no IN ( .
implode(',', $_POST['questions_groups']) . );
but if I can enter dodgy values in the questions_groups form field,
you're hosed.

Re: [PHP] Nested foreach ?
Not working.
foreach($_SESSION['skills'] as $key = $skill)
{
$query = INSERT INTO table (skill, sky, sku)
VALUES ('$skill',
{$_SESSION['skys'][$key]},{$_SESSION['slus'][$key]});
//run query
}
The foreach is generating an invalid argument.
I'm just going to show again what I have set up:
There are five for each of these:
input name=skill[] type=text id=skill[]/td
select name=sky[] id=sky[]
select name=slu[] id=slu[]
Then I post the session variables as:
$_SESSION['skills'] = $_POST['skill'];
$_SESSION['skys'] = $_POST['sky'];
$_SESSION['slus'] = $_POST['slu'];
It looks like the loop above is using the $skills
array to advance through the other arrays ?

How about this:
// Doing this makes the code below easier to read
$skills = $_SESSION['skills'];
$skys = $_SESSION['skys'];
$slus = $_SESSION['slus'];
// Set up the fixed part of teh query
$query = INSERT INTO table (skill, sky, sku) VALUES (;
// Loop through each set of form elements
foreach($skills as $key = $skill)
{
$query .= '$skill','{$skys[$key]}','{$slus[$key]}',;
}
$query = rtrim($query, ','); // Remove any comma from end of $query
$query .= ')'; // Close VALUES (
echo $query; // What do you get?
// RUN QUERY HERE

RE: [PHP] Nested foreach ?
These lines store the FORM's posted values (arrays) into your SESSION: $_SESSION['skills'] = $_POST['skill']; $_SESSION['skys'] = $_POST['sky']; $_SESSION['slus'] = $_POST['slu']; These lines get your SESSION variables (arrays) and put them into 'local' script array variables. If you are doing these then you MUST have done the above in the previous script. $skills = $_SESSION['skills']; $skys = $_SESSION['skys']; $slus = $_SESSION['slus']; If you are doing it all in one script just use: $skills = $_POST['skills']; $skys = $_POST['skys']; $slus = $_POST['slus']; Make sense? If not, may I suggest you do a bit of reading on PHP and form processing before proceeding. I have found the PHP manual extremely useful. With it (and some googling) I have gone from zero PHP knowledge 10 months ago to being able to develop and maintain an entire PHP/MySQL based web application subscribed to by several clients.

Re: [PHP] Nested foreach ?
Okay, I will try - I have these three fields in a form for user input. There are 10 sets of these, i.e. Users can enter three sets of skills, with the yearsused and when last used. I have set them up as arrays, since it's probably not wise to manage 30 seperate variables. I'm using session variables: $_SESSION['skills'] = $_POST['skill']; $_SESSION['skys'] = $_POST['sky']; $_SESSION['slus'] = $_POST['slu']; My problem is I do not know how to get these into the database with one query. Hope this is clearer.

Re: [PHP] Nested foreach ?
John,
Sorry, I'm not trying to be unclear.
There are 3 columns in the table.
In the user form. there are 30 fields, 10 text and 20
dropdown.
The 10 text are:
$_SESSION['skills'] = $_POST['skill'];
The first dropdown is :
$_SESSION['skys'] = $_POST['sky'];
The second dropdown is:
$_SESSION['slus'] = $_POST['slu'];
So I need to grab the input and
enter into database
where each set of skill, sky , slu is a new record.
I hope this is clearer.

Re: [PHP] Nested foreach ?
Stuart,
Having read what you've written so far, you may want to try something
like this.
In your HTML (I've left the selects empty, but you can see what I mean):
input type=text name=skills[0][name] /select
name=skills[0][years] /select name=skills[0][used] /
input type=text name=skills[1][name] /select
name=skills[1][years] /select name=skills[1][used] /
input type=text name=skills[2][name] /select
name=skills[2][years] /select name=skills[2][used] /
...
input type=text name=skills[9][name] /select
name=skills[9][years] /select name=skills[9][used] /
Then in PHP
?php
foreach ($_POST['skills'] as $skill)
{
$skillname = $skill['name'];
$yearsused = $skill['years'];
$lastused = $skill['used'];
...
}
?
Hope this helps
Cheers
Chris

Did you read the answer I gave?
foreach($skills as $key = $skill)
{
echo $skill - {$skys[$key]} - {$slus[$key]}\n;
}
Now adapt that to your session variables and query:
foreach($_SESSION['skills'] as $key = $skill)
{
$query = INSERT INTO table (skill, sky, sku) VALUES ('$skill',
{$_SESSION['skys'][$key]},{$_SESSION['slus'][$key]});
//run query
}
or, if you can use extended inserts:
$insert = array();
foreach($_SESSION['skills'] as $key = $skill)
{ $insert[] =
('$skill',{$_SESSION['skys'][$key]},{$_SESSION['skus'][$key]});
}
$query = 'INSERT INTO table (skill,sky,sku) VALUES ' . implode(',',$insert);
//run query
