Hello Experts,

Trying to understand how fpdf works... not easy....
all the examples i could find with mysql are tables with column headers.

i need something like this:

Names of partners: $name1, $name2, $name3
when the WHILE loops only on the variables AND not keep repeating the " Names of partners:"

here is part of the code from where i loop. i tired many variations with no luck.

 
while($row = mysql_fetch_array($result)) {
$partner_fname = $row['partner_fname'];
$partner_lname = $row['partner_lname'];
$ownerName = "Owner`s Name: ". $partner_fname. $partner_lname;
	
$i = 0;
$pdf->Cell(0,10,$ownerName, 0, 10);
$i = $i + 1;

Click on the "Manual" link and you will see the methods listed with a description of what their arguments

i need something like this:

Names of partners: $name1, $name2, $name3
when the WHILE loops only on the variables AND not keep repeating the " Names of partners:"

Try:
...
if( 0==mysql_num_rows($result) )
{
	echo 'No results found';
}
else
{
	$row = mysql_fetch_assoc($result);
	$ownerName = "Owner`s Name: ";
	do{
		$ownerName .= $row['partner_fname']. ' ' .$row['partner_lname'];
	
		$i = 0;
		$pdf->Cell(0,10,$ownerName, 0, 10);
		$i = $i + 1;
...
		$ownerName ='';
	}while($row = mysql_fetch_assoc($result));
}

Hi hielo

thank you! the only problem i still have is to have keep the two variables in the same line e.g. $name1, $name2, $name3. currently they appear line after line break. i tried this but it still does not work.

$pdf->Cell(0,10,$ownerName,0,0);

Something like this should work:

$pdf->Write("Owner's Name: ");

$numberOfRows = mysql_num_rows($sql);
$rowNumber = 1;

while($row = mysql_fetch_array($result)) {

	$pdf->Write( $row['partner_fname'] . " " . $row['partner_lname']);
	
	// Output comma between names
	if($rowNumber < $numberOfRows)
	{
		$pdf->Write( ", " );
	}	
}

Also have a look at this for more stylish text output:

// INITIALIZE THE STRING
$string = "Owner's Name: ";

// USE AN ITERATOR TO GET THE PARTNER NAMES
while($row = mysql_fetch_array($result)) 
{
    // ADD THE PARTNER NAMES TO THE STRING
    $string .= "$row['partner_fname'] $row['partner_lname'],";
}

// REMOVE THE EXTRANEOUS TRAILING COMMA
$string = rtrim($string, ',');

// PUT THE STRING INTO THE PDF CELL
$pdf->Cell(0,10,$string, 0, 10);

Hi Ray_Paseur... your knowledge in almost every 'zone' i posted in is incredible!

this line $string .= "$row['partner_fname'] $row['partner_lname'],";  have a problem so i removed the quotes but now it prints the name right after the other without the "," nor space.

thanks!

thank you! the only problem i still have is to have keep the two variables in the same line e.g
It sounds like some of those items may have trailing newlines. Try:
...
if( 0==mysql_num_rows($result) )
{
	echo 'No results found';
}
else
{
	$row = mysql_fetch_assoc($result);
	$ownerName=array();
	while($row = mysql_fetch_assoc($result))
	{
		$ownerName[]= trim($row['partner_fname']). ' ' .trim($row['partner_lname']);
	}
	$ownerName='Owner`s Name: '.implode('', $ownerName);
	$pdf->Cell(0,10,$ownerName, 0, 0);
}

@hielo: Good idea about using trim() on the variables.  In the snippet at ID:36502452 is line 8 extraneous?  Also the implode on line 14 might need a comma between the quotes like implode(',', $ownerName)

>>In the snippet at ID:36502452 is line 8 extraneous?... comma...
Good catch. I copied from my original post and completely missed that fetch() after changing from do{}while() to while().
...
if( 0==mysql_num_rows($result) )
{
	echo 'No results found';
}
else
{
	$ownerName=array();
	while($row = mysql_fetch_assoc($result))
	{
		$ownerName[]= trim($row['partner_fname']). ' ' .trim($row['partner_lname']);
	}
	$ownerName='Owner`s Name: '.implode(', ', $ownerName);
	$pdf->Cell(0,10,$ownerName, 0, 0);
}

Thanks for your kind words.  I only pay attention to the PHP zone, but with the way EE works with multi-zone postings I may appear to be in two places at once ;-)

Yes, the Write function requires an extra argument specifyin the line height. You can experiment with that. Here is a correction.

And again the tip also given by hielo: use the manual. :-)

$pdf->Write(10, "Owner's Name: ");

$numberOfRows = mysql_num_rows($sql);
$rowNumber = 1;

while($row = mysql_fetch_array($result)) {

	$pdf->Write( $row['partner_fname'] . " " . $row['partner_lname']);
	
	// Output comma between names
	if($rowNumber < $numberOfRows)
	{
		$pdf->Write( 10, ", " );
	}	
}

hielo thank you. i feel like this would never end....

i took you script and run it....
if the company have 3 owners and only 1 email it prints the email 3 times....

It sounds like each of those owners are using the same email OR your query is wrong.  If you think the query is correct and you want unique email list, then change:
 $emails='Company Emails: '.implode(', ', $emails);

to:
 $emails='Company Emails: '.implode(', ', array_unique($emails) );

BUT, if your db has (like I said, "It sounds like each of those owners are using the same email" ):
John, a@b.com
Sally, a@b.com
Mary, X@b.com

then using the array_unique() fix, will result in:
John, Sally, Mary
a@b.com, X@b.com

making it seem as if though Sally "owns" X@b.com and Mary doesn't have an email. I don't know about you, but given that specific example I would rather have:

John, Sally, Mary
a@b.com, a@b.com, X@b.com

hi hielo, thank you, thank you...

i am trying the mysql query in phpmyadmin... the problem is solved having the array_unique. the problem was not in query... for some reason it was printing the same email 3 times...

the problem in query is that i have 3 WHERE statements and when one return false unfortunately i have a blank page. i should i guess create multiple sql queries.
