PHP loop not displaying properly

Question

I need some help with a looping problem. For my example code below, I have two Mysql tables:

tblDepRatesCats:

ID 
header 
left_text 
center_text 
right_text 
header_order

------

tblRates_balance:

id 
depratecat 
MinBalance 
InterestRate 
APY 
suborder

The tblDepRatesCats.ID = tblRatesBalance.depratecat . For each row in tblDepRatesCats , there may be 0 or 1 or more rows in tblRates_balance .

I'm trying to display the results of querying these tables so that it shows each tblDepRatesCats data with the corresponding tblRates_balance data, but instead it is showing tblDepRatesCats so that if tblDepRatesCats row has 3 tblDepRatesCats rows associted with it, the tblDepRatesCats row is repeated 3 times with one row of tblDepRatesCats '

As you can see below "Super Now Checking Account" is displayed 3 times, but what I want is for it to display just once with the 3 results for minimum balance and apy listed under the one header.

NOW Checking Accounts Minimum Daily Balance to Earn APY Annual Percentage Yield $1000 10

Super NOW Checking Account Minimum Daily Balance to Earn APY Annual Percentage Yield % $2222 2

Super NOW Checking Account Minimum Daily Balance to Earn APY Annual Percentage Yield % $2100 25

Super NOW Checking Account Minimum Daily Balance to Earn APY Annual Percentage Yield % $2000 20

Money Market Accounts Minimum Daily Balance to Earn APY Annual Percentage Yield % $3000 30

Below is my test code. Any help would be greatly appreciated.

$result = mysql_query('SELECT tblDepRatesCats.*, tblRates_balance.* FROM tblDepRatesCats JOIN tblRates_balance ON tblDepRatesCats.ID = tblRates_balance.depratecat ORDER BY tblDepRatesCats.header_order, tblRates_balance.suborder;');

while ($row = mysql_fetch_assoc($result)) 
{
 echo ("<table width=\"98%\" border=\"0\" bgcolor:\"#ffffff\"><tr><td>");
 echo ("" . $row["header"] . " <br>");
 echo ("" . $row["left_text"] . "&nbsp;&nbsp;");
 echo ("" . $row["right_text"] . "");
 echo ("</tr></td>");
 // &nbsp temporarily added
 echo ("<tr><td>");
 echo ("" . $row["MinBalance"] . "");
 echo ("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
 echo ("" . $row["InterestRate"] . " <br><br>");
 echo ("</tr></td>");
}

Just move the output you don't want to be repeated each time to outside of the while loop...

echo ("<table width=\"98%\" border=\"0\" bgcolor:\"#ffffff\"><tr><td>");
echo ("" . $row["header"] . " <br>");
echo ("" . $row["left_text"] . "&nbsp;&nbsp;");
echo ("" . $row["right_text"] . "");
echo ("</tr></td>");
echo ("<tr><td>");
while ($row = mysql_fetch_assoc($result)) 
{
    //&nbsp temporarily added
    echo ("" . $row["MinBalance"] . "");
    echo ("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
    echo ("" . $row["InterestRate"] . " <br><br>");
}
echo ("</tr></td>");

If I am understanding you right, then all you need to do is shift around your code:

$result = mysql_query('SELECT tblDepRatesCats.*, tblRates_balance.* FROM tblDepRatesCats JOIN tblRates_balance ON tblDepRatesCats.ID = tblRates_balance.depratecat ORDER BY tblDepRatesCats.header_order, tblRates_balance.suborder;');
$new_result = array();
while ($row = mysql_fetch_assoc($result)) 
{
  $new_result[$row["header"]][] = $row;
}

foreach($new_result as $new_row){
  echo ("<table width=\"98%\" border=\"0\" bgcolor:\"#ffffff\"><tr><td>");
  echo ("" . $new_row[0]["header"] . " <br>");
  echo ("" . $new_row[0]["left_text"] . "&nbsp;&nbsp;");
  echo ("" . $new_row[0]["right_text"] . "");
  echo ("</tr></td>");

  foreach($new_row as $row){
   // &nbsp temporarily added
   echo ("<tr><td>");
   echo ("" . $row["MinBalance"] . "");
   echo("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
   echo ("" . $row["InterestRate"] . " <br><br>");
   echo ("</tr></td>");
  }

  //also, dont forget to close the table:
  echo "</table>";
}

The way your code was was starting a new table everytime you went through your loop

edit to avoid warning. Though it might make more sense to find a way to not need to have to call $result[0]["xxxxx"] at all. Maybe a static variable would be easier, though a second query to get just those values might be what you are looking for. It just depends

Answer 3

Use left join if there can be 0 links between tables. Using join only will result rows that have no data in balance table to be dropped out from results.
