this is probably something very simple and i'm just making it more difficult than it has to be. i have a php page, which just has a checkbox and a button. when i click the button it should call my "collection.php" page and then update my index page on the status. i took out most of my code in collection.php and my index page still doesn't update. what am i doing wrong?? thanks in advance!
index.php

collection.php
<?
// movie search variables
$dir = "/video/Movies/";
$movie_extensions = array('mkv','mp4','m4v','avi');
$update_movies = 0;
if(isset($_POST["update"]))
$update_movies = $_POST["update"];
// read contents from $dir
if (is_dir($dir)){
if ($dh = opendir($dir)){
while (($file = readdir($dh)) !== false){
$file_info = pathinfo($file);
$output_string['worked'] = 'found <span style="color:yellowgreen;">' . $file . '</span><br />';
echo json_encode($output_string);
}
closedir($dh);
}
}
when i remove the echo portion from the collection script i receive a response (below works):
$output_string['worked'] = 'testing';
echo json_encode($output_string);
once i add that back to the loop it errors.
as a test i added a for loop in there - it also fails:
for($i=0;$i<10;$i++)
{
$output_string['worked'] = 'found <span style="color:yellowgreen;">' . $file . '</span><br />';
echo json_encode($output_string);
}
console.log(output_string);the results and post it please? – We0 Aug 16 at 14:45
