create dropdown from array

Hi,

i have this form for create dropdown from array

<?php 
/* Array Contents */

$array_p = array('product1','product2','product3','product4','product5');
echo '<select name="product[]" multiple>';

for ($i = 0; $i < count($array_p); $i++)
{
echo '<option value="' . ($i + 1) . '">' . $array_p[$i] . '</option>';
} 
echo'</select>';
?>

Now I would like to begin with an array like this and enter into the Option Value the price as VALUE using this array:

$array_p = array([{"price1":"10","name":"product1"},
{"price2":"25","name":"product2"},
{"price3":"25","name":"product3"},
{"price4":"25","name":"product4"},
{"price5":"15","name":"product5"}]);

I tried, but I have not gotten results.

thenks a lot

Hi Cornelio,

The data in your last example isn't really an array - it's a string that contains a JSON encoded array, try using json_decode('your_string', true); to convert it back to an array.

Hi Bob,
thank you very much for your attention, as always.
sorry for my bad english, probably the post has been set wrong.
I try to synthesize

a) I'm a dropdown multiple-select like this;

<?php
$content = '{"values":[{"price":10.5,"product":"book1688px"},{"price":10,"product":"book2356px"},{"price":70,"product":"book3421px"}]}';
    
	$jsonArray = json_decode($content, false);?> 
	<div>
	<select name="product[]" multiple>
	<?php 
     foreach($jsonArray->values as $jsonValue) { 
	 ?>
<option value="<?php echo $jsonValue->price; ?>">€ <?php echo $jsonValue->price; ?>--><?php echo $jsonValue->product; ?></option>
<?php } 
?>
</select>

b) in the setup in custom code I included: echo json_encode ($ form-> data ['product']);


c) they select the e.g. the first 3 products;

d) on submit to get the array corresponding to the value of the select with this result: ["1", "2", "3"];

question:

in practice how to format an array like ours ($ content) and save it to db for use in a dropdown like this?

Regards
Cornelio

Hi Cornelio,

I don't really understand what your question is :-(

Is it useful to set the price as the value of the drop-down options? Is that enough to identify the product uniquely?
