EDIT:
It seems some people don't know what i mean, first of all i'm working with PHP
This is my problem,
There are multiply input fields in my form with the same name, i have made a array from the names and now i want the values of the array into my database
It tried this but it isn't working,
for( $i = 1; $i <= 5; $i++ ){
$nummer = $_POST['factuurnaam'];
$des = $_POST['beschrijving[]'.$i];
$amount = $_POST['aantal[]'.$i];
$prijs = $_POST['prijs[]'.$i];
$sql = mysql_query("INSERT INTO `facturen`(`beschrijving`,`aantal`, `prijs`, `factuurnaam`) VALUES ('".$des."','".$amount."','".$prijs."','".$nummer."')") or die(mysql_error());
}

Answer 1

you can use array_shift function to get value from all parameter, further for your information in php $variables work fine inside double quotes! see the modified code.
for ($i = 1; $i <= 5; $i++) {
$nummer = $_POST['factuurnaam']; // NOTE: variable not mentioned in HTML form ?
$des = array_shift($_POST['beschrijving']);
$amount = array_shift($_POST['aantal']);
$prijs = array_shift($_POST['prijs']);
$sql = mysql_query("INSERT INTO `facturen` (`beschrijving`,`aantal`, `prijs`, `factuurnaam`)
VALUES ('$des','$amount','$prijs','$nummer')"
) or die(mysql_error());
}

Answer 2

To count the input fields:
$texttofind = "<input";
echo 'Number of inputfields: ' . substr_count($input, $texttofind);
http://php.net/manual/en/function.substr-count.php
Insert html into the database is as easy as adding any string to the database, only you have to escape it like this:
$html = mysql_real_escape_string($input);
http://php.net/manual/en/function.mysql-real-escape-string.php
$input has to be your html.

Answer 3

I think this what what you will need,
$beschrijving = $_POST['beschrijving'];
$aantal = $_POST['aantal'];
$prijs = $_POST['prijs'];
as all are in the same number, so we can loop any of them
for($i=0;$i<count($beschrijving );$i++){
$sql = mysql_query("INSERT INTO `facturen` (`beschrijving`,`aantal`, `prijs`) VALUES ('$beschrijving[$i] ','$aantal[$i] ','$prijs[$i] ')"
)
}
I hope this will help you.
