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
}
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...
Note: You can just make a single file out of it to achieve your wanted output Use mysql_real_escape_string() to sanitize the passed-on value to prevent SQL injections You should use mysqli_* instead of the deprecated mysql_* API Form them in a single file like this (display.php): <html> <form method="post" name="display"...
Your PHP is checking if $_POST['submit'] contains a value. Your form does not contain a form element with the attribute name="submit", so therefore it fails and moves straight to the else statement. If you want to check if the form was posted then you should instead check for: if (!empty($_POST))...
As @Darkbee stated, the simplest way is to have the file outside your website root. This would be accessible on the server, but not to the public under any circumstances. The alternative is to set the permissions to 400 on the file. .htaccess could block access, but not blocking access...
Closures work just like a regular function. You need to inject your outer scope variables into function's scope. Mail::send('invoices.mail', array($pinvoices,$unpinvoices), function($message) use ($email) { $message->to($email , 'Name')->subject('your invoices '); }); ...

Then we use realpath() which conveniently returns false if file does not exist. All you have to do is specify a relative...
