Increment double-bracket PHP arrays to SQL - php

Question

Here is a example of what my form looks like.
<div>
<input name="address[1][name]" type="text">
<input name="address[1][street]" type="text">
<input name="address[1][city]" type="text">
<input name="address[1][phone]" type="text">
</div>
<div>
<input name="address[2][name]" type="text">
<input name="address[2][street]" type="text">
<input name="address[2][city]" type="text">
<input name="address[2][phone]" type="text">
</div>
...
I'd like to increment the data obtained from each block in PHP and increment it into my database with MySQL.
What is the best way to achieve this ?
I know it generates arrays, but I do not know how to deal with the "double-bracket" method (the form "aaa[x][bbb]" probably has a proper name, which I do not know, I'm sorry).
Thanks.

Answer 1

If you want to iterate over all fields using double brackets, the best structure to use are nested foreach's:
$formdata = $_POST['address'];
foreach($formdata as $group)
{
$SQLFields = array();
$SQLValues = array();
foreach($group as $field => $value)
{
// Here you have each individual field inside each group, so you can
// build the fields of the INSERT statement.
$SQLFields[] = $field;
$SQLValues[] = $value;
}
// Now assemble everything, and your INSERT is ready.
$SQL = "insert into table (".
implode(", ", $SQLFields).
") values ('".
implode("', '", $SQLValues).
"')";
// Run the SQL statement the way you want.
}

I think you are looking for something like this:
$data = $_POST['address'];
foreach($data as $address) {
//your address-object (name, street, city, phone)
var_dump($address);
//Add your sql-query in here and DO NOT forget to escape your received data
}
