[SOLVED] Why doesn't this pedigree work?

forTheDogs · August 11, 2007

Greetings! Most of my database pages are generated through a program but it does not generate the pedigree for me.

Until around May 15, I had never heard of PHP or mySql so, as you can probably guess, I am having a difficult time trying to get this to work.

With the help of several people and a great deal of reading on my part, here is what I have so far - I do not get errors any more but it does not print out a pedigree either.

[You can look at the current result, if it would help, at fortheloveoflabradors.com/labradors/login.php and log in as 'guest'. To get a good example, search for BrookHill Mike - he has 8 generations entered].

Thanks so much even if you just took the time to look at this!!! For me, it is very daunting!!

global $conn;

$message =

$DogR = db_query($DogQ,$conn);

Shouldn't you be using $SireGGrandSireRow in the last two levels?

And from middle of your code you are writing data into pedigree array under the same key values.

if ($SireGGrandSireR) {
  $SireGGrandSireRow = mysql_fetch_array ($SireGrandSireR, MYSQL_ASSOC);
  $pedigree['DamGrandGrand'] = $SireGGrandSireRow['RegName'];
  $pedigree['DamGrandGrandSireID'] = $SireGGrandSireRow['SireID'];
  $pedigree['DamGrandGrandDamID'] =$SireGGrandSireRow['DamID'];
  $message.= "<td class=shade>GrandGrandDam - ".$SireGGrandSireRow ['RegName']."</td>";   
}

I would use other way to get those data.

Split this task into two parts - get the data, output data.

  $pedigree = array();
  
  $sql    = "SELECT RegName, SireID, DamID FROM Pedigrees WHERE ID in (%s)";
  
  $result = mysql_query(sprintf($sql, $values['ID']));

  if ($result) {
    $row = mysql_fetch_assoc($result);
    $pedigree[$row['ID']] = $row;
    
    $newIDs = array();
    if (!empty($row['SireID'])) $newIDs[] = $row['SireID'];
    if (!empty($row['DamID'])) $newIDs[]  = $row['DamID'];
    
    $level = 1;
    $maxlevel = 3;
    while (count($newIDs) > 0 && $level <= $maxlevel) {
      
      // select all current anc.
      $newIDs = array();
      $ancres = mysql_query(sprintf($sql, Implode(", ", $newIDs)));
      if ($ancres) {
        while ($row = mysql_fetch_assoc($ancres)) {
          $pedigree[$row['ID']] = $row;
          if (!empty($row['SireID'])) $newIDs[] = $row['SireID'];
          if (!empty($row['DamID'])) $newIDs[]  = $row['DamID'];
        }
      }
      
      ++$level;
    }

    $row = $pedigree[$values['ID']];
    // prepare empty output assoc array with first Reg value.
    $outped = array('Reg' => $row['RegName'], 
            'Sire' => '', 'Dam' => '', 'SireSire' => '', 'SireDam' => '', 'DamSire' => '', 'DamDam' => ''
            ....
            );
    if (!empty($row['SireID']) && isset($pedigree[$row['SireID']])) {
      $sirerow = $pedigree[$row['SireID']];
      $outped['Sire'] = $sirerow['RegName'];
      
      if (!empty($sirerow['SireID']) && isset($pedigree[$sirerow['SireID'])) {
        $SireSire = $pedigree[$sirerow['SireID']];
        $outped['SireSire'] = $SireSire['RegName'];
        if (!empty(......
          // another anc.
        }          
      }
      if (!empty($sirerow['DamID']) && isset($pedigree[$sirerow['DamID']])) {
        $SireDam = $pedigree[$sirerow['DamID']];
        $outped['SireDam'] = $SireDam['RegName'];
        if (!empty(...
          // another anc.
        }
      }  
      
    } 
    
    if (!empty($row['DamID']) && isset($pedigree[$row['SireID']])) {
      $damrow = $pedigree[$row['SireID']];
      $outped['Dam'] = $damrow['RegName'];
      
      if (!empty($damrow['SireID']) && isset($pedigree[$damrow['SireID']])) {
        $DamSire = $pedigree[$damrow['SireID']];
        $outped['DamSire'] = $DamSire['RegName'];
        if (!empty(....
          // another anc.
        }
      }
      
      ....
    }
  
    // output data
    $message  = "<table cellspacing=1 cellpading=1><tr><td colspan=4 align=center class=blackshade>Pedigree Table</td></tr>";
    $message .= "<tr><td colspan=8 class=shade>RegName - ".$outped['Reg']."</td></tr>";
    $message .= "<tr><td rowspan=4 class=shade>Sire - ".$outped['Sire']."</td><td rowspan=4 class=shade>Dam - ".$outped['Dam']."</td></td>";
    $message .= "<tr><td rowspan=2 class=shade>SireSire - ".$outped['SireSire']."</td>".
                    "<td rowspan=2 class=shade>SireDam - ".$outped['SireDam']."</td>".
                    "<td rowspan=2 class=shade>DamSire - ".$outped['DamDam']."</td>".
                    "<td rowspan=2 class=shade>DamDam - ".$outped['DamDam']."</td>".
                    "</tr>";
    ....

  }

Thanks to both of you for your input!!!

I am having a problem with fitting suggestions into the files that were generated by the database program I used [i suppose I should not call it a db program as I did the db myself, it just does the pages on the web site that allows viewing and access - another words - the really hard parts!!!]. So, I have gone through and done my best to understand everyone's suggestions so that what I have works with what I have. I came up with the following but it has one huge problem - it does not know what to do when it reaches a dog without a sire ID # and it's probably about 45,000 times longer than it needs to be.

Here is enough of it so you can see what I am doing. I ended up with a whole big bunch of arrays - each one taking the sire or dam from the previous one and gathering its name, ID's etc.

Is there some way I could make one big array that includes all the little ones I have and then include a 'while' statement that if there is not a SireID [or DamID], it just puts 'unknown' in the name of that ancestor and then goes on to the next one? Almost all my arrays are eventually going to hit a NULL value and I just want them to continue on to the next one.

By the way, this is all included in an 'event' file that runs before the pedigree page is viewed.

////////

global $conn;
$message = "<table><tr><td>Pedigree Table</td></tr>";
$sql = "SELECT ID,RegName, SireID, DamID FROM Pedigrees WHERE ID=";

$DogQ = $sql . $values["ID"];
$DogR = db_query($DogQ,$conn);

$row = mysql_fetch_array ($DogR, MYSQL_ASSOC);
    $row = array (
'RegName' => $row['RegName'],           
'SireID' => $row['SireID'],           
'DamID' => $row['DamID']);	

//Get Sire
$SireQ = $sql . $row['SireID'];    
$SireR = mysql_query ($SireQ);
           
$SireRow = mysql_fetch_array ($SireR, MYSQL_ASSOC);         
	$SireRow = array (
	'RegName' => $SireRow['RegName'],           
	'SireID' => $SireRow['SireID'],           
	'DamID' => $SireRow['DamID']);	

//Get PatGrandSire info
	$PatGrandSireQ = $sql . $SireRow['SireID'];
	$PatGrandSireR = mysql_query ($PatGrandSireQ);

	$PatGrandSireRow = mysql_fetch_array ($PatGrandSireR, MYSQL_ASSOC);         
		$PatGrandSireRow = array (
		'RegName' => $PatGrandSireRow['RegName'],           
		'SireID' => $PatGrandSireRow['SireID'],           
		'DamID' => $PatGrandSireRow['DamID']);	

//Get Pat1GGrandSire info
		$Pat1GGrandSireQ = $sql . $PatGrandSireRow['SireID'];
		$Pat1GGrandSireR = mysql_query ($Pat1GGrandSireQ);

            $Pat1GGrandSireRow = mysql_fetch_array ($Pat1GGrandSireR, MYSQL_ASSOC);         
			$Pat1GGrandSireRow = array (
			'RegName' => $Pat1GGrandSireRow['RegName'],           
			'SireID' => $Pat1GGrandSireRow['SireID'],           
			'DamID' => $Pat1GGrandSireRow['DamID']);

And to print:

$message.="<tr style=color: rgb(102, 153, 0); background-color: rgb(255, 255, 204); align=left><td class=shade valign=middle rowspan=16 colspan=1 width=150><small><small><small>
Sire<br /><b>".$SireRow['RegName']."</b></small></small></small></td>
		<td class=shade valign=middle rowspan=8 colspan=1 width=170><small><small><small>
PatGrandsire<br /><b>".$PatGrandSireRow['RegName']."</b><br>
		</small></small></small></td>
		<td class=shade valign=middle rowspan=4 colspan=1 width=180><small><small><small>
Pat1GGrandSire<br /><b>".$Pat1GGrandSireRow['RegName']."</b><br>
		</small></small></small></td>
		<td class=shade valign=middle rowspan=2 colspan=1 width=190><small><small><small>
Pat1GGGrandSire<br /><b>".$Pat1GGGrandSireRow['RegName']."</b>
		</small></small></small></td>
		<td class=shade valign=middle><small><small><small>
Pat1GGGGrandSire<br>
		</small></small></small></td>
	</tr>";
$message.="<tr style=color: rgb(102, 153, 0); background-color: rgb(255, 255, 204); align=left><td class=shade valign=middle width=221><small><small><small>
Pat1GGGGrandDam<br>
		</small></small></small></td>
	</tr>";

Etc, etc, etc.

Thank you so much for looking at this!!! I hope one can understand what I am trying to say!!

I think all you need to add is few if statements

//Get Sire
  if (is_numeric($row['SireID'])) {
   $SireQ = $sql . $row['SireID']; 
   ....  
//Get PatGrandSire info
    if (is_numeric($SireRow['SireID'])) {
      $PatGrandSireQ = $sql . $SireRow['SireID'];
      ....
   //Get Pat1GGrandSire info
      if (is_numeric($PatGrandSireRow['SireID'])) {
         $Pat1GGrandSireQ = $sql . $PatGrandSireRow['SireID'];
         ....

      }//PatGrandSireRow[sireID]

    }//SireRow[sireID]

  }//row[sireID]

///////////

// in outputting data you just check wheter is your array set
<small>
Sire
".(isset($SireRow) ? $SireRow['RegName'] : '')."</small>

forTheDogs · August 13, 2007

WOW Thank you so much!!!! I got an error the first time I tried it but then I added an

else{

'RegName' = 'Unknown'

}

So now if the Sire is available, it works. But if he is not, then I get a message that says undeclared or undefined variable or something like that.

Any suggestions? I thought I was getting better at figuring out what was wrong, but I have a very tenous hold on my understanding of how this is working and that error does not seem to be what my mind is focused on right now ??? ???

Also, I don't understand the last part of the code you gave me the ISSET . . .

Is that just to check the arrays or is it important in some other way?

Take a look though at how close I am:

Thank you somuch for your help!!!!

Barand · August 13, 2007

Tried the link - just got a parse error

gurroa · August 13, 2007

This construct

echo (isset($SireRow) ? $SireRow['RegName'] : '');

is the same as

  if (isset($SireRow)) echo $SireRow['RegName'];
  else echo '';

php function isset() returns true/false if the variable is set or not.

see http://www.php.net/manual/en/function.isset.php

forTheDogs · August 14, 2007

Hi!! It should work. You probably just got there at the wrong time [i have been trying to get the table right and keep making little mistakes].

http://fortheloveoflabradors.com/labradors/menu.php

I lost my cell formatting so it is not easy to ready but it WORKS!!! As long as there is a sire, that is!!

Still have not figured out the "undefined variable" message I am getting when there is no sire!!

Thanks!!!

Barand · August 14, 2007

OK, that works. I clicked the "view" link for a couple of dogs - one ok, one gave an error message.

Incidentaly, that pedigree chart is just like the one my code (above) creates.

I did a search for one of my labradors (registered name "Loopy Lupus") but no success

forTheDogs · August 14, 2007

This is what I ended up with so that it works now even if the Sire or Dam ID are blank:

///////

if (isset($PatGrandSireRow['SireID']))

$message.="<td valign=middle class=shade rowspan=8 colspan=1 width=170>

PatGrandsire ".$PatGrandSireRow['RegName']."</td>";

else $message.="<td valign=middle class=shade rowspan=8 colspan=1 width=170>Unknown</td>";

/////

Thank you so much for all your help!!

I am so sorry you could not find your Lab in our database! What are his parents names? I don't recognize a kennel name in his registered name.

You are my heroes!!!!!!!!!!!

Barand · August 14, 2007

Prob because my two are UK registered.
