array input with php

[megetron]

hi,

I need to save array of elements form INPUT html element to a database, and on other page I need to display it again, so I need to SET the INPUT element again.

here is th input array:

<input type='hidden' name='elements[]' value='$categories' />"

 

how do I do that?

Thank you.

you need to serialise the data before you put it into the database:

 

<?php
//preparing for inserting into db
$array = array(1,2,3,4,5,6,7);
$readyForDb = serialize($array);

//extracting from db
$array = unserialize($row['from the db']);
