I am working on a php code as shown below which lists all the mp4 files present in a $src_dir .
$src_dir = ('\\\ABCD-ST-001\Audio_Test\podcast\incoming_folder');
$mp4_files = preg_grep('~\.(mp4)$~', scandir($src_dir));
print_r(array_values($mp4_files)); // LineA
Here is the O/P obtained from Line#A :
Array ( [0] => 36031P.mp4 [1] => hello.mp4 )
Now, I have used the following script in my php code in order to insert those mp4 files in Podcast_Export
table.
foreach ($mp4_files as $value) {
$db->exec(SELECT COUNT(*) FROM Podcast_Export WHERE House# = '".$value."' AND status = 'GO');
$db->exec("INSERT INTO Podcast_Export ('House_number', 'Status') VALUES ('".$value."', 'Go')"); // Line B
}
The above script add the following data inside Podcast_Export
table:
36031.mp4 Go
hello.mp4 Go
Problem Statement:
The issue which I am facing right now is when I refresh the page, the script at LineB is run again and mp4 files present in a $src_dir is added again inside Podcast_Export
table as shown below:
36031.mp4 Go
hello.mp4 Go
36031.mp4 Go
hello.mp4 Go
It should work in a way that once new file comes up inside $src_dir then it should add inside Podcast_Export
table. Let us suppose the new file is hxz210.mp4 then the content inside Podcast_Export
table should be:
36031.mp4 Go
hello.mp4 Go
hxz210.mp4 Go
Your selection is fine, but you need to store result into an variable like:
$count = $db->querySingle("SELECT COUNT(*) as count FROM Podcast_Export WHERE House_number = '".$value."'");
if($count <= 0){
$db->exec("INSERT INTO Podcast_Export (House_number,Status)
VALUES ('".$value."', 'Go')");
}
Using querySingle
to get the no of rows in SQLite.
note that, i have chanaged the House#
to House_number
here and removed AND status = 'GO'
clause as all of them having GO
status.
