PHP logic help

[simeonC]

Here I have three form elements

<td colspan="6">Intended Payment Method 
        
<input type="checkbox" name="payment_method[]" id="checkbox" value="cash">      
Cash
<input type="checkbox" name="payment_method[]" id="checkbox2" value="check">
Check 
<input type="checkbox" name="payment_method[]" id="checkbox3" value="credit/debit">
Credit/Debit
</td>

I would like to insert them into a database with the following conditions, however I have no idea how to construct these conditions.

Condition 1: if there is no records which indicate the Intended payment method Insert that which have been checked.

Condition 2: if there is a record for the customer which indicates an intended payment method and the user is attempting to change these settings using the same fields.

  -Check what payment method have been inserted the mysql database

  -Check if the new payment methods inserted match whats in the database; if so do nothing to that row

if the option has been unchecked or checked update the database to meet that condition

 

As you can see below I have not gotten far because I am fluent with php to that which you would consider mastery. Any help will be greatly appreciated.

if (isset($payment_method) && is_array($payment_method)) { 
	$count_insert=count($payment_method);
	$payment_count_query=mysql_query("SELECT * FROM payment_option");
	$count_query=mysql_num_rows($payment_count_query);
	echo $count_query; echo $count_insert;
	
	if ($count_query==0){
		foreach ($payment_method as $value){
			$insert_method==mysql_query("INSERT INTO payment_option (repair_id,payment_method) VALUES ('$_SESSION[repair_id]','$value')");
			}//end foreach statment where query count equals 0
		}//end of queyr count
	
	if ($count_query>0){
		
		foreach ($payment_method as $value){
			
			while ($payment_fetch=mysql_fetch_array($payment_count_query)){
				if ($payment_fetch['payment_method']==$value){}else{
					mysql_query("UPDATE payment_option SET ");
					
					}/// I was lost at this point because I can see the outcome not being what I had in mind///////
				
				}
			
			}///end foreach statement count_query<0
		
		
		}//end if statment for query count==1
	   
}//end of if payment method was set

well since everyone seemed to overlook my post. Not to sure if it was hard to understand. I will just post my answer to my own post.

$payment_method=$_POST['payment_method'];//the check box array from forum
	$payment_count=count($payment_method);//count of elements in the array
	list($a, $b, $c) = ($payment_method); // use the list function to take each value and place them into a variable in the following order these variables are used in my query. 

//if no checkboxes are selected we do nothing 

//if you one item has been selected we perform the following action//

if ($payment_count==1) { $query_count=mysql_query("SELECT * FROM payment_option WHERE repair_id='$_SESSION[repair_id]'");

$count=mysql_num_rows($query_count);//we count the option in the database to see if it exist

 

///if not we insert the checked elements into the data base

if ($count==0){$insert_options=mysql_query("INSERT INTO payment_option (repair_id,`$a`) VALUES ('$_SESSION[repair_id]','$a')");}

 

////if there is an item in the database already we delete it and insert the new options

if ($count>0){$delete_query=mysql_query("DELETE FROM payment_option WHERE repair_id='$_SESSION[repair_id]'");

$insert_options=mysql_query("INSERT INTO payment_option (repair_id,`$a`) VALUES ('$_SESSION[repair_id]','$a')");

 

}

 

}

///Here the same logic above is used same format for the next two options just added the listed variables into the query

elseif ($payment_count==2){

$query_count=mysql_query("SELECT * FROM payment_option WHERE repair_id='$_SESSION[repair_id]'");

$count=mysql_num_rows($query_count);

 

if ($count==0){$insert_options=mysql_query("INSERT INTO payment_option (repair_id,`$a`,`$b`) VALUES ('$_SESSION[repair_id]','$a','$b')");}

 

if ($count>0){$delete_query=mysql_query("DELETE FROM payment_option WHERE repair_id='$_SESSION[repair_id]'");

$insert_options=mysql_query("INSERT INTO payment_option (repair_id,`$a`,`$b`) VALUES ('$_SESSION[repair_id]','$a','$b')");

}

 

}

elseif  ($payment_count==3){

$query_count=mysql_query("SELECT * FROM payment_option WHERE repair_id='$_SESSION[repair_id]'");

$count=mysql_num_rows($query_count);

 

if ($count==0){$insert_options=mysql_query("INSERT INTO payment_option (repair_id,`$a`,`$b`,`$c`) VALUES ('$_SESSION[repair_id]','$a','$b','$c')");}

if ($count>0){$delete_query=mysql_query("DELETE FROM payment_option WHERE repair_id='$_SESSION[repair_id]'");

$insert_options=mysql_query("INSERT INTO payment_option (repair_id,`$a`,`$b`,`$c`) VALUES ('$_SESSION[repair_id]','$a','$b','$c')");

}

 

}

 

I just have a feeling that there was a shorter way to do this if so please post so i can learn as I age thank you
