[Resolved] send array in hidden field

spighita

Hi:
How can I send an array in a hidden field.

This is an example of what I have

<?PHP
$colors=array('red','blue','gray','white','black');
print_r($colors);

?>



<FORM METHOD=POST ACTION="test3.php">


<INPUT TYPE="hidden" name="test[]" value="<?PHP echo $colors ?>">



<INPUT TYPE="submit" name="sub" >

</FORM>



<?PHP


if(isset($_POST['sub'])){
	echo "<H2>THIS IS WHAT THE FORM READS</H2>";
	print_r($test);
}



?>

Thanks in advance for anyone who helps

I think you can serialize it if you want: http://www.php.net/serialize

I haven't tried it, but from the looks of it, it should work just fine.

This should work as is, except you may need to change this:

<?PHP 


if(isset($_POST['sub'])){ 
    echo "<H2>THIS IS WHAT THE FORM READS</H2>"; 
    print_r($test); 
} 



?>

To this:

<?PHP 


if(isset($_POST['sub']))
{
$test = $_POST["test[]"];
foreach ($test as $i => $value) 
{
    echo "<H2>THIS IS WHAT THE FORM READS</H2>"; 
    print_r($value); 
} 
}


?>

The form won't pass the array.

I also thought of maybe including all the array in one string and then exploding the string into an array.

You could reiterate the array into the input array...

<?php
$colors = array('red','blue','gray','white','black');
foreach($colors  as $c) {
?>
<input type="hidden" name="test[]" value="<?php echo $c; ?>">
<?php
}

Small typo:

$test = $_POST["test[]"];

should be

$test = $_POST["test"];

Here I got it to work.

Thanks to everyone.

<FORM METHOD=POST ACTION="test3.php">

<?php 
$colors = array('red','blue','gray','white','black'); 

foreach($colors as $c) { 

?> 
<input type="hidden" name="test[]" value="<?php echo $c; ?>"> 
<?php 
} 
?>




<INPUT TYPE="submit" name="sub" >

</FORM>




<?PHP  


if(isset($_POST['sub'])){  

    echo "<H2>THIS IS WHAT THE FORM READS</H2>";  

    print_r($test);  

	foreach($test as $var => $result){
		echo "<H2> $var = $result </H2>";
