Developemnt on win2003 server. Final server will be linux
Apache,Mysql and PHP is being used.
I use 2 scripts(form and process).
The form displays multiple dynamic rows with chechboxs, input box for units of service, description of the service and each row has its own dropdown list of unit fees that apply.
Each dynamically created row will return 3 values fee1_choice, fee1_unit and fee1_money.
Note The above informaton is coming from a mysql database.
When the service is submitted the selected information is displayed to the secreen by the process.
Note: When I get it displaying to the screen, I will work on inserting the information into a mysql database.

I have identified my problem as being the arrays and I am stuck.
For testing I tried 3 different types of loops to identify the problem with the values in arrays
(the results are below).
If I select the first row in the dynamically created rows the correct fee1_choice, fee1_unit and fee1_money values are passed to be displayed.
If I select the second or any other row in the dynamically created rows the correct code_id only is passed. No fee1_unit and fee1_money are displayed


1) What is the best way to for me to use arrays to collect dynamically created information with the multiple checkbox selections?
2) should I use a two-dimentional array instead of seperate arrays for the 3 fields?
3) When the user selects any number of checkboxes Should not only the selected item(s) be in the array?
4) Should not the array be starting at index 0 for the while and for loop? Note: see results below.
5) If 3 selection boxes are chosen should not the array only loop 3 times?

Thanks in advance

The short varsion of my problem is:
The 3 arrays on the same dynamically created row are not insync.
The selectbox array starts at index 0, the input box array starts at index 3 and dropdown selection array starts at index 3.
How do I get all 3 arrays to return values and starting at index 0?
I don't know much about two-dimentional arrays is that the answer?
When I have to insert into the database can I seperate a two-dimentional arrays into distinctive columns?

Solution part A:
Changing to a for loop and incrementing the array indexes using $i
syncronize the arrays and solves on problem.

$result = mysqli_query($mysqli,$data);
$num_rows = mysqli_num_rows($result);
for($i=0; $i < $num_rows; $i++)
 $row = mysqli_fetch_array($result);
        list($code_id, $fee1_code, $description, $general_fee, 
             $technical_fee, $specialist_fee, $anaesthetist_fee,
      $non_anaesthetist_fee) = $row;
 echo"<tr height=\"10\">
      <td width=\"4%\" bgcolor=\"#fff8dc\" align=\"center\">
         <input type=\"checkbox\" name=\"fee1_choice[$i]\" value=\"$code_id\"></td>
             <td width=\"7%\" bgcolor=\"#fff8dc\" ><span class=\"style20\"><strong>$fee1_code</strong></span></td>
             <td width=\"3%\" bgcolor=\"#eeeee0\" height=\"10\">
         <input type=\"text\" name=\"fee1_unit[$i]\" size=\"1\" maxlength=\"2\" value =\"$fee1_unit\"/>
            <td width=\"79%\" bgcolor=\"#eeeee0\" class=\"style20\"> $description </td>
            <td width=\"6%\" align=\"left\">$s_fee</td>\n";

Solution part B:
The code below works great in removing the unnecessary indexes with no values. Providing the same count for the 3 arrays so using a loop is now possible.

$code_id = (array_filter($code_id));
$fee1_unit = (array_filter($fee1_unit));
$fee1_money = (array_filter($fee1_money));

Current Challenge
I was previously using a for loop, the problem is if the array index does not start at 0 (zero) it throws your looping off so you can't combine count() and starting your loop at $row = 0.

for($row = 0; $row < count($code_id); $row++)
    echo $code_id[$row].", ".$fee1_unit[$row].", ".$fee1_money[$row];
     echo "<br/>";

The other options for looping which work are the foreach() and while() loops
where you don't need to determine the length of the array.
I have played with the foreach.

$all = array($code_id,$fee1_unit,$fee1_money);
foreach ($all as $key => $value)
 echo "$key<br>";
 foreach($value as $key2 => $val2)
  echo " $key2 => $val2<br>";

Foreach() result:
2 => 2036
3 => 5287
4 => 2032
2 => 2
3 => 3
4 => 4
2 => 36.30
3 => 12.51
4 => 145.10
How do I structrue a foreach or while loop so I can sync up the arrays indexs and values for inserting as rows as array[index] like in the for loop?

echo $code_id[$row].", ".$fee1_unit[$row].", ".$fee1_money[$row];

check out php's array_values function, which will essentially reindex the arrays

Thanks I will check out your suggestion.

Solution part C
I think I have the method of accomplishing what I need.
Do you see and down side to using this code or have another suggestion that would be best?

$code_id = (array_filter($code_id));
$fee1_unit = (array_filter($fee1_unit));
$fee1_money = (array_filter($fee1_money));
$indices1 = array_keys($code_id);
foreach($indices1 as $index1)
    echo $code_id[$index1].", "; 
    echo $fee1_unit[$index1].", "; 
    echo $fee1_money[$index1], "<br/>";

The results correspond with the database contents for the 4 service selected.
Displayed are services, units and fee.

5287, 1, 12.51
2032, 2, 145.10
2028, 3, 51.00
2051, 4, 15.55

yup, either way is probably fine -- whichever way works.. I can't see any benefits of doing it one way or the other
