Question

I have a small problem 🙂 I was searching the web but didn’t find any solutions.

I have a value like this (got it from $_GET[])

tag1, tag2, tag3, tag4

and all I want to do is insert it into MySql (via PHP) like this:

+---------+-------------+
|      id |         tag |
+---------+-------------+
|      33 |        tag1 |
|      33 |        tag2 |
|      33 |        tag3 |
|      33 |        tag4 |
+---------+-------------+

I found many articles about this on Stack Overflow but the biggest problem here is that I don’t know how many values I’m gonna get each time (I did not find that answer).

I will appreciate any help I get.

Hi greetings from UK 🙂
Can’t you just loop through the querystring fields and add one row to the database at a time?

e.g.

<?php

$id = 33;
$value_list = 'tag1,tag2,tag3,tag4';
$values = explode(',', $value_list);
foreach ($values as $value)
{
    $sql = "INSERT INTO table (id, value) VALUES ($id, '$value');";
    //.. execute SQL now
    echo '<p>' . $sql . '</p>';
}

?>
