Form a Javascript array and submit to php

[searls03]

I am trying to form a form that has one field that will be an array because there are multiple fields with the same name and id that will be generated from it.

PHP Code:

<form class="responseForm"  action="javascript:parseResponse123<?php echo $id; ?>()" id="responseForm<?php echo $id; ?>"> <input name="hiddenField5<?php echo $id; ?>" id="hiddenField5<?php echo $id; ?>" type="hidden" value="<?php echo $id; ?>" />
<input name="hiddenField4<?php echo $id; ?>" type="hidden" id="hiddenField4<?php echo $id; ?>" value="<?php echo $qty; ?>" />

<font color="red"><?php echo $val; ?></font><br />
<?php
$i=1;
while($i<=$qty)
  {
?>
Participant <?php echo $i; ?>:<input name="hiddenField2<?php echo $id; ?>[]" id="hiddenField2<?php echo $id; ?>[]" type="text" /><br />
<?php  $i++;
  }
  ?>
 <input name="submit" type="submit" value="Submit" />
</form>

Then I want to use javascript to form the array for the hiddenfield2 parameter and use this code to submit to insert.php

<script type="text/javascript">
function parseResponse123<?php echo $id; ?> () 
{
	var hiddenField2<?php echo $id; ?> = $("#hiddenField2<?php echo $id; ?>");
	var hiddenField4<?php echo $id; ?> = $("#hiddenField4<?php echo $id; ?>");
	var hiddenField5<?php echo $id; ?> = $("#hiddenField5<?php echo $id; ?>");
	var hiddenField1<?php echo $id; ?> = $("#hiddenField1<?php echo $id; ?>");

	var url = "insert.php";
	
		$.post(url,{  hiddenField2[]: hiddenField2<?php echo $id; ?>.val(),hiddenField: hiddenField5<?php echo $id; ?>.val(), hiddenField1:hiddenField1<?php echo $id; ?>.val(), hiddenField4:hiddenField4<?php echo $id; ?>.val()  } , 
		function(data) {
	
		});
		setTimeout(function() {

		$.ajax({
		type:"POST",
		data:"getNews=true",
		success: function(r){
			$("#newsContent").html(r);
			
		},
		error: function(){
alert($(".hiddenField2<?php echo $id; ?>").val());		
	$("#error").text($(".hiddenField2<?php echo $id; ?>")).fadeIn(300)
		}
	})


	},200);
}

</script> 
<?php

then decode the array using php(I have not gotten this far as I haven't been able to submit any formed array)


any help from anyone?

Without looking at your code, this is how I send an array in a form using the hidden input tag.

Turn the array into a string using join():
BigString = MyArray.join(); <= this is javascript

Put that in the hidden field.
To get an array back in the php use the explode:

$MyArray = explode(",", $string); <= This is php
