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
}

Don't do that. It's effectively forging the from address and will fail SPF checks. Instead, use your own address as the From address, and add the submitted address as a reply-to address. In PHPMailer: $mail->From = '[email protected]'; $mail->addReplyTo($POST['emailfrom']); ...

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.

$x and $y are only defined within the scope of the function. The code outside of the function does not know what $x or $y are and therefore will not print them. Simply declare them outside of the function as well, like so: <?php function sum($x, $y) { $z =...
Only values that are sent by a form will be in the GET or POST array. From what you are showing I conclude that you don't want to show the field in your form, so make it hidden. Add this inside your form tag: <input name="price" type="hidden" value="'.$price.'" class="inputClass"> Also,...

I don't know the source of the array $arr = array();, but it is assigned to null before the insert query. So it means, literally you are inserting nothing into the database. So check your array well, maybe it was to be like $arr = array('name'=>'My Name', 'url'=>'url', 'email'=>'my email',...
