Insert array values and single form values into all rows PHP MYSQL

Question

Could someone tell how to write this insert into a database? The below code is an example of what I am trying to accomplish. I want to have a form for families with multiple children. They submit their family names and one id that they will share in the database. See code below...

FORM INPUTS

<input type="text" name="fname[]"/>
<input type="text" name="lname[]"/>
<input type="text" name="fname[]"/>
<input type="text" name="lname[]"/>
<input type="text" name="family_id"/>

This is where I am having troubles. I can submit the family names but only the first(row) "name" is storing the "family_id" as well.

PHP

        foreach($_POST['fname'] as $key => $fname) {
            $lname = $_POST['lname'][$key];
                            $family_id = $_POST['family_id'][$key];

            $query = mysql_query("INSERT INTO Table (FName, LName, Family_ID ) VALUES ('{$fname}', '{$lname}', $_POST['family_id'])"); 
        } 

I appreciate any help!

Answer 1

Missing {} around $_POST['family_id'] .
family_id insn't an array.

So the first iteration you get

$_POST['family_id'][0]; // gets the id

The second

$_POST['family_id'][1]; // gets undefined index

To fix it do the following.

Add the following code before foreach loop and concat $family_id to the query like you did with the others.

$family_id = $_POST['family_id'];

Answer 2

Try this:

extract($_POST);
$total=count($fname);

for($i=0;$i<count($total);$i++)
{

$fname=$fname[$i];
$lname=lfname[$i];

 $query="INSERT INTO Table (FName, LName, Family_ID ) VALUES ('{$fname}', '{$lname}', $family_id)";

}
