Foreach stops executing after 1 loop

[pocobueno1388]

I have a program where the user can select multiple categories, then multiple cities. It should loop through each category, then download a file for each chosen city for that category.

 

<?php

if ($_POST['export']){

$categories = $_POST['categories'];
$cities = $_POST['cities'];

foreach ($categories AS $category){

	foreach ($cities AS $city){

		$keyword = new keyword(FALSE, $category, $city);
		$keyword->export();

		$file = ("keywords.csv");
		header ("Content-Type: application/octet-stream");
		header ("Accept-Ranges: bytes");
		header ("Content-Length: ".filesize($file));
		header ("Content-Disposition: attachment; filename=$category - $city");
		readfile($file);

	}
}		
}

?>

 

I'm pretty sure the loop isn't the problem. I think it's all the headers that are for someone reason stopping the execution. It will download the FIRST file, but then completely stops. It should automatically start multiple downloads.

 

I'm thinking it's something to do with one of the headers...like only one download can happen at once.

 

Any help would be greatly appreciated, Thanks!

You can only output one set of headers and the corresponding file contents per HTTP request.

 

You can either dynamically produce a set of 'download links' on a page so that the visitor can click on each of them or you would need to zip the contents of all the files into a single download.

Try output buffering, maybe? Or add each file to a compressed archive and download just the archive? Just some thoughts, not sure how good they are . . .

Okay, the zip file solved my problem. Thanks for the advice!
