How do I make these fields autopopulate from the database?
- by dmanexe
I have an array, which holds values like this:
$items_pool = Array (
[0] => Array ( [id] => 1 [quantity] => 1 )
[1] => Array ( [id] => 2 [quantity] => 1 )
[2] => Array ( [id] => 72 [quantity] => 6 )
[3] => Array ( [id] => 4 [quantity] => 1 )
[4] => Array ( [id] => 5 [quantity] => 1 )
[5] => Array ( [id] => 7 [quantity] => 1 )
[6] => Array ( [id] => 8 [quantity] => 1 )
[7] => Array ( [id] => 9 [quantity] => 1 )
[8] => Array ( [id] => 19 [quantity] => 1 )
[9] => Array ( [id] => 20 [quantity] => 1 )
[10] => Array ( [id] => 22 [quantity] => 1 )
[11] => Array ( [id] => 29 [quantity] => 0 )
)
Next, I have a form that I am trying to populate. It loops through the item database, prints out all the possible items, and checks the ones that are already present in $items_pool.
<?php foreach ($items['items_poolpackage']->result() as $item): ?>
<input type="checkbox" name="measure[<?=$item->id?>][checkmark]" value="<?=$item->id?>">
<?php endforeach; ?>
I know what logically I'm trying to accomplish here, but I can't figure out the programming.
What I'm looking for, written loosely is something like this (not real code):
<input type="checkbox" name="measure[<?=$item->id?>][checkmark]" value="<?=$item->id?>" <?php if ($items_pool['$item->id']) { echo "SELECTED"; } else { }?>>
Specifically this conditional loop through the array, through all the key values (the ID) and if there's a match, the checkbox is selected.
<?php if ($items_pool['$item->id']) { echo "SELECTED"; } else { }?>
I understand from a loop structured like this that it may mean a lot of 'extra' processing.
TL;DR - I need to echo within a loop if the item going through the loop exists within another array.
