Question

I have here a code wherein I have an array of checkbox populated with mysql data through a query. I can successfully submit the value of the checked checkbox into a table in a database. But what I want to do is to save it according to the sequence the checkbox was checked by the user. I was told that I can achieve this through javascript but unfortunately, I’m not familiar with javascript at all. If possible, can you provide steps on achieving this through PHP only? If not, can you please guide me on how to achieve this using javascript since I’m a newbie. Here’s my sample code to let you imagine what I’m trying to do..

<?php
require("aacfs.php");
echo"<div align= center >
  <table width=300 border= 1 align= right><tr><th align=center bgcolor=silver><font face=consolas>Choose Itinerary</font></th></tr>
    <tr>
      <td></br>
      <form method=post>"; 


$result=mysql_query(" select * from itinerary group by location");
    $y=mysql_affected_rows();
    for($i=0;$i<$y;$i++)
    {$row=mysql_fetch_array($result);
        $pr=$row['icode'];
        $n=$row['location'];
        $l=$row['btime'];
echo"<table border=1 align=center width=250>
          <tr><td width=15><input name=prod[] type=checkbox value='$pr'></td><td>$n</td></tr>
          </table>";
        $t=$_POST[prod];

        }
echo"</td></tr></table>";

echo"      

    <table width= 664 border= 1  align= left >
    <tr><td height= 282 ><p align= center  class= style77>
<p align= right ><h4>$d</h4></p>
<p align= center ><font face=consolas><b>Itinerary List</b></font></p>
<p align=center><font face=consolas>To change your itinerary list, choose again.</font></p>

<br>
  <center><input name=add  type= submit  value='Add to Itinerary List'></center>
<br>  
<table width=654  border= 1>
  <tr bgcolor = silver align=center>
    <td>Itinerary</td>
    <td>Block Time</td>

 </tr></form>";


 if(isset($_POST['add']))
{           
if(isset($_POST[prod]))
 {  foreach($t as $k)
    {$result=mysql_query("select * from itinerary where icode='$k'");
    $y=mysql_affected_rows();

for($x=0;$x<$y;$x++)
{$row=mysql_fetch_array($result);
        $r=array($row['icode']);
        $n=$row['location'];
        $p=$row['btime'];   



    echo"<form method=post><tr>
<td>$n</td>
<td>$p</td>
 </tr>";

    $a=$_POST[pro];
    $stat1='Not Submitted';

foreach($r as $a=>$l)
{

$kdot=mysql_query("select max(reservno) as 'maxr' from reservation") or die(mysql_error());
$row2=mysql_fetch_array($kdot);
$fi=$row2['maxr'];
mysql_query("insert into location_list(reservno, icode, location, status) values('$fi', '$l', '$n', '$stat1')") or die(mysql_error());
}
}}}

}

Clarifications are most welcome. Hope you can help me! Thanks a lot!

Got the detection of checked checkbox sequence through this code:

<script type="text/javascript"> 
<!--

$(document).ready(function(){

    var array = [];


    $("input[type=button]").click(function(){
    for (var i = 0; i < array.length; i++){  
    if (array[i] == $(this).attr('value')){  
    array.splice(i, 1);  
    }  
    }  
    alert(array.length);
    });




    $('input[type="checkbox"]').click(function(){

    if ($(this).attr('checked')){
    // Add the new element if checked:  
    array.push($(this).attr('value'));
    //alert(array2.push($(this).attr('name')));
    }

    else{ 
    // Remove the element if unchecked:  
    for (var i = 0; i < array.length; i++){  
    if (array[i] == $(this).attr('value')){  
    array.splice(i, 1);
    }
    }
    }






        $("#result").show(function(){
        $(this).val("");
        for (var i = 0; i < array.length; i++){
    $(this).val($(this).val() + " " + array[i]+ "\n");
        }
        });

    });

}); 
//--> 
</script>

I’m binding it in my checkbox.

$result=mysql_query(" select * from itinerary group by location");
    $y=mysql_affected_rows();
    for($i=0;$i<$y;$i++)
    {$row=mysql_fetch_array($result);
        $pr=$row['icode'];
        $n=$row['location'];
        $l=$row['btime'];
echo"<table border=1 align=center width=250>
          <tr><td width=15>
          <input type='checkbox' value='$n -> $l' id='cb1'>
</td><td>$n</td><td width=4>$l</td></tr>
          </table>";

Then output it in a textarea.

<textarea name=resulta id='result' style='height:200px; width:350px' disabled='disabled'></textarea>

I can save it in my database through this:

echo "<form><center><input type=submit name='pindot' value='Gora Men~'></center></form>";
$val=$_POST['resulta'];
if (isset($_POST['pindot']))
{
$lines = explode("\n", $val);

foreach ($lines as $line) {
    // $line here is a string
    // build a query based on it and execute it
    mysql_query("insert into postflight (sample_lang) values ('$line')") or die(mysql_error());

};
}

Thank you all for your help! God bless!
