Question

I have a php script that looks like this:

    $contacts["{$firstname}"]    =  $_POST["{$firstname}"] ;
$contacts["{$lastname}"]    =  $_POST["{$lastname}"] ;
$contacts["{$age}"]    =  $_POST["{$age}"] ;


    $collection->insert($contacts);

so this works fine but i all of these values are going into my collection as “fistname”, “lastname” and “age” with quotes around all. I want the quotes around first name and last name but i want the age field to insert as a number/integer not a quoted string. How do I make sure that the age field and other numeric fields go into the mongodb/collection as a number?

I was thinking something like: integer -> $_POST[“{$age}”] but im sure that’s not right. Again im using PHP not the shell. Thnaks.

Thank you for your help.

Answer 1

First, you don’t need all those quotes and braces. Second, try casting the value to an int

$contacts = array(
    $firstname => $_POST[$firstname],
    $lastname  => $_POST[$lastname],
    $age       => (int) $_POST[$age]
);

I’m assuming here that all the $_POST vars have been checked and validated and $firstname, $lastname and $age are all valid array key strings
