Hi all,
Im busy moving a site from localhost to hosted server and im baffled as to why mysqli simply wont run.
The following script iscalled after a captcha script has been satisfied, but it just doesnt seem to like the Mysqli. I have converted other simple mysqli scripts, but this one is giving me a big headache.
Is Mysqli something that can be activated in .htaccess?
Any help is appreciated.
Thanks
<?php
//set up a couple of functions
function doDB() {
global $mysqli;
//connect to server and select database; you may need it
$mysqli = mysqli_connect("localhost", "------", "---------", "--------");
//if connection fails, stop script execution
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
}
function emailChecker($email) {
global $mysqli, $check_res;
//check that email is not already in list
$check_sql = "SELECT id FROM SUBSCRIBERS WHERE email = '".$email."'";
$check_res = mysqli_query($mysqli, $check_sql) or die(mysqli_error($mysqli));
