POST to Array trouble

Hi Chaps,

I have a Query that calculates a Quote for a job/jobs for a given project.
As there can be more than one job for a project, I have to loop through the query and present the data in a table.
Users have the option to ‘override’ the estimated quote and enter a ‘custom quote’.
The ProjectID, JobID and TableInfo are part of my 1st Array, the estimated/custom quote figure and the ‘override’ option are part of my 2nd Array.
The information is then POSTed to a script file that joins the information together and then updates the relevant Table/JobID based on the figures and override options.

Example of HTML Code:

<form action="CompleteQuoteSingle.php" method="post" enctype="multipart/form-data">
  <table border="0" cellpadding="0" cellspacing="0">
    <caption><input type="submit" id="button" value="Submit" /></caption>
    <tr>
      <th>Project No.</th>
      <th>Project Title</th>
      <th>Job Title</th>
      <th>Type</th>
      <th>Language</th>
      <th>Deadline</th>
      <th>Document Format</th>
      <th>Pages</th>
      <th>Word Count</th>
      <th>Net Total</th>
      <th>EN Proofreading Cost</th>
      <th>Total</th>
      <th>Admin Override</th>
    </tr>
    <script type="text/javascript"> 
		$(function() {
     	var jobquote = $('#jobquote_328');
     	var value = jobquote.val();
     	$('#jobadminquote_328').click(function() {
          if (jobquote.attr('readonly')) {
               jobquote.removeAttr('readonly');
               jobquote.val('');
		} 
		else {
               jobquote.attr('readonly', 'readonly');
               jobquote.val(value);
          		}
     	});
	});
	</script>

            $query = sprintf("

			//$mess = $ref = $_SERVER['HTTP_REFERER']; header( 'refresh: 0; url=../../projects/project_details.php?id='.$projid);
        }
    		else {
			// run your SQL query here to update $table where row matches $rowid
            $query = sprintf("
			UPDATE $table

		}
	}
}

My problem is:
The Override option only gets passed to the Array, if selected. This means that if I have two jobs, and I select the override option for the second job, the array looks like this:

Array
(
[jobquote] => Array
(
[0] => 358.80
[1] => 100
)

[jobinfo] =&gt; Array
    (
        [0] =&gt; tbl_jobs:328:1111
        [1] =&gt; tbl_jobs:335:1111
    )

[jobadminquote] =&gt; Array
    (
        [0] =&gt; y
    )

)

Question:
Is there a way of POSTing a default value of ‘n’ for the ‘jobadminquote’ checkbox, so that the above would look like:

[jobadminquote] => Array
(
[0] => n
[1] => y
)

I hope this is clear?!

Above the


<input type="checkbox" name="jobadminquote[]" id="jobadminquote_328" value="y" />

put


<input type="hidden" name="jobadminquote[]" id="jobadminquote_328" value="n" />

if I do that, it cancels out the JQuery ‘read-only’ attribute. . .
If I place the ‘hidden’ field underneath, the array for both results in ‘n’
