foreach multidimensional Array and insert database - php

Question

got a problem.
I got form like this
<input name="product[sub_name][]">
<input name="product[price][]">
<input name="product[random][]">
<input name="product[just_field][]">
I can add many blocks of this form pressing "add more".
Recieving posta data i do the stuff.
$field = $_POST['product'];
foreach ($field as $key => $values) {
foreach($values as $value) {
$key.' - '.$value;
}
}
I need code to insert multiple rows in database depending on posted rows. Problem is that, i dont know how to get only, for example, "price". Goal is insert all data in database. Hope you guys understand my logic.
Here is print_r output. I can got more possibilities than two
Array (
[sub_name] => Array ( [0] => New car [1] => New bike )
[standart_price] => Array ( [0] => 100 [1] => 300 )
[cupon_price] => Array ( [0] => 50 [1] => 200 )
[max_purchases] => Array ( [0] => 1000 [1] => 100 )
)

Answer 1

You can get a more ordered result if you re-organize the array to contain the index first:
<input name="product[$index][sub_name]">
<input name="product[$index][price]">
<input name="product[$index][random]">
<input name="product[$index][just_field]">
Each time you add a new product change the index with javascript, in that way, when you recieve the data in php you can do something like:
$products = $_POST['product'];
foreach ($products as $product)
{
$sub_name = $product['sub_name'];
$random = $product['random'];
$just_field = $product['just_field'];
$sql = "Your SQL query"
$mysqli->query($sql);
}
Maybe need a little more work changing the html indexes with javascript but your code become more clear.
p.s. That's the general idea, i don't test it.

Answer 2

Try to use
print_r($_POST["product"]);
to output the whole array.
Are you sure the values transmitted by the formular are passed into $_POST ?
Could you please post the output.

Check this out..
<?
//Connect to DB.
$link = mysqli_connect("HOST","USERNAME","PASSWORD","DATABASE") or die("Error " . mysqli_error($link));
//Consider your table structure in MYSQL. Don't depend on this structure.
//CREATE TABLE TBL1(SLNO PRIMARY KEY AUTO_INCREMENT, DETAIL_VALUE VARCHAR(200));
foreach( $_POST['product'] as $key => $value )
{
//Get specific Tag.
if( $key == 'price')
{
//Creating Query to insert.
$query = "insert into TBL1('DETAIL_VALUE') VALUES('".addslashes($value)."')";
$mysqli_query($link, $query) or die;
}
}
?>

$mysqli = new mysqli("localhost", "root", "password", "db name");
$field = $_POST['product'];
foreach ($field['price'] as $idx => $price)
{
$sub_name = $field['sub_name'][$idx];
$random = $field['random'][$idx];
$just_field = $field['just_field'][$idx];
$sql = "INSERT INTO table (sub_name, random, just_field, price) VALUES ('{$sub_name}','{$random}','{$just_field}','{$price}')";
$mysqli->query($sql);
}
