I make some AJAX (PHP + JQuery), but I have one problem. I have: dataType:"json",
in Javascript
Everything works fine when json_encode returning some records from DB. The problem is what to do, how to say server in case that there are not any records?
When I have an array which is encoded to JSON is ok. WHen array is empty the json_enocde returning NULL. But this is not in expected format so I can't catch this error.
Hope, question is clear :)
Here are two (of several) possibilities:
PHP Option:
Handle the NULL object to make it parseble ahead of time...
if ($mydata==NULL) {
$mydata = new stdClass();
}
echo json_decode($mydata);
JS Option:
Try catching the error when parsing it on the client side.
// Catch the error
try {
var data = JSON.parse(json);
} catch(error) {
// Handle the error
}
Actually, you should reserve in config/app.php file. Then, you can add In the Service Providers array : 'Menu\MenuServiceProvider', In the aliases array : 'Menu' => 'Menu\Menu', Finally, you need to run the following command; php artisan dump-autoload I assume that you already added this package in composer.json Sorry, I didn't...

This is one way to do it, using preg_match: $string ="SomeStringExample"; preg_match('/^[b-df-hj-np-tv-z]*/i', $string, $matches); $count = strlen($matches[0]); The regular expression matches zero or more (*) case-insensitive (/i) consonants [b-df-hj-np-tv-z] at the beginning (^) of the string and stores the matched content in the $matches array. Then it's just a matter...
