Passing an array as hidden variable

[joshi_v]

Hello everyone!


Can you tell me how to pass an array as hidden variable? is it possible? If so please give me an example.

Do you mean you want to pass a group of values in a form as a hidden field?  If so then I'd suggest something like this in your form

[code]<input type="hidden" name="myformarray" value="This,Is,An,Array,Of,Words">[/code]

Then make your php look like this:

[code]
<?php
$myarray = explode(",", $_POST['myformarray']);

echo "<pre>\n";
var_dump($myarray);
echo "</pre>\n";
?>
[/code]

Thanks for response!


exactly what i am tryign to do is passing an array like .

i tried it but it is showing empty array even though there are some values in the actual array i am trying to pass.

[code]$array_name=array("1","2","3");
<input type="hidden" name="test_array" value="<?=$array_name;?>">[/code]


So please  tell me how to pass this as hidden?

Oh, you need to do that the other way around...

[code]<?php
$array_name = array(1,2,3);
$myvarstring = implode(",", $array_name);
?>

<input type="hidden" name="test_array" value="<?=$myvarstring;?>">[/code]

So you mean we can't post an array directly as it is, right?

Anyway i am going to use your suggestion.


Thanks once again!

Not as far as I'm aware.

You can also serialize the array, pass the serialized value and unserialize it when you process the form.
[code]<?php
<?php
$array_name = array(1,2,3);
$myvarstring = htmlentities(serialize($array_name),ENT_QUOTES);
?>

<input type="hidden" name="test_array" value="<? echo $myvarstring;?>">
?>[/code]
