This script will create an xls file from the data that is sent to it
When I run this it only gets one recored and it is supposet to get all
the records that are past by the $_POST[selectedcontactlist]
I think I have a } in the wrong place but I can not figure it out
anybody have a suggestion
$_POST[selectedcontactlist]="3,45,65,23,12,4,56"; //this is a sample of
what is past
$ExplodeIt = explode(",",rtrim($_POST[selectedcontactlist],","));
$Count = count($ExplodeIt);
for ($i=0; $i < $Count; $i++) {
$sql = "SELECT * FROM contacts WHERE id = '$ExplodeIt[$i]'";
Instead of doing that, do this:
/**
* This section makes sure the id's you are going to use in your query
are actually integer id's.
* If they aren't, you'll get an sql error.
*
*/
$ids = array();
foreach ($_POST['selectedcontactlist'] as $id) {
if (!is_int($id)) {
continue;
}
$ids[] = $id;
}
// all posted values are duds? show an error.
if (empty($ids)) {
echo "No id's are numeric, try again";
exit;
}
$sql = "select * from contacts where id in (" . implode(',', $ids) . ")";
That'll get everything for all of those id's and then you can loop over
it all once:
// print out the header for the csv file here.
// then loop over the results:
while ($row = mysql_fetch_assoc($sql_result)) {
// put it into file here.
}
// close the file
// print it out.
Or you can do it straight from MySQL, which is a lot faster:
SELECT [fields] INTO OUTFILE '/path/to/file.csv' FIELDS TERMINATED BY
',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM [tables]
WHERE [conditions]
If you want a header row, then you can use a UNION statement.
