Re: pg_fetch_row Problem

Hi Cameron,

I think the reason is you're going beyond the number of results you have
for that query.

Rewrite the while(...) loop to look like this:

$result_count = 0;
while($result_count < $count) {
$row = pg_fetch_row($result, $result_count);
.........
}

See if that works.

Chris.

going on here??????? I am including my script here below so you can see
what it is doing, maybe you all can see something im not: <?php
pg_connect("host=172.18.74.10 port=5432 dbname=acquisuite_db
user=pgadmin password=pgadmin")
or die ( 'Unable to

printf("Connected

if (isset($HTTP_GET_VARS['panel'])) {
$MM_param1__panels = $HTTP_GET_VARS['panel'];
}
$MM_param2__panels = ''%'';
if (isset($HTTP_GET_VARS['startdate'])) {
$MM_param2__panels = $HTTP_GET_VARS['startdate'];
}
$MM_param3__panels = ''%'';
if (isset($HTTP_GET_VARS['enddate'])) {
$MM_param3__panels = $HTTP_GET_VARS['enddate'];
}
$MM_param4__panels = ''%'';
if (isset($HTTP_GET_VARS['order'])) {
$MM_param4__panels = $HTTP_GET_VARS['order'];
}

$query = sprintf("SELECT * FROM %s WHERE utctime AT TIME ZONE 'MST'
BETWEEN '%s' AND '%s' ORDER BY utctime %s",
$MM_param1__panels,$MM_param2__panels,$MM_param3__panels,$MM_param4__pan
els);

$result = pg_exec($query);
$count = pg_num_fields($result);

for ($i = 0; $i < $count; $i++){
$header .= pg_fieldname($result,$i)."\t";
}

while($row = pg_fetch_row($result,$result_count++)){
$line = '';
foreach($row as $value){
if(!isset($value) || $value == ""){
$value = "\t";
}else{
# important to escape any quotes to preserve them in the data.
$value = str_replace('"', '""', $value);
# needed to encapsulate data in quotes because some data might be multi
line. # the good news is that numbers remain numbers in Excel even
though quoted.
$value = '"' . $value . '"' . "\t";
}
$line .= $value;
}
$data .= trim($line)."\n";
}
# this line is needed because returns embedded in the data have "\r" #
and this looks like a "box character" in Excel
$data = str_replace("\r", "", $data);

# Nice to let someone know that the search came up empty.
# Otherwise only the column name headers will be output to Excel. if
($data == "") {
$data = "\nno matching records found\n";
}

# This line will stream the file to the user rather than spray it across
the screen
header("Content-type: application/octet-stream");

# replace excelfile.xls with whatever you want the filename to default
to
header("Content-Disposition: attachment; filename=excelfile.xls");
header("Pragma: no-cache");
header("Expires: 0");

echo $header."\n".$data;
?>

Any Help would be appreciated.
Thanks,
