Good day to you all,

If yo can find the time to assist me, it would be appreciated.

Thanks in advance

<?php
$dbhost                         = "xxxxx";
$dbuser                         = "xxxx";
$dbpass                         = "xxxxxx";
$dbname                         = "xxx";

$mysqli =  new mysqli($dbhost, $dbuser, $dbpass,$dbname) or die ("Error connecting to database");
if ($mysqli->connect_errno){

Do print_r($result) after line 18 to see what exactly it contains.

query returns false on failure, so I suggest you add error checking. Has to be a database issue then.

Melvita,
I can see I have missed out the y in mysqli, so I have corrected this and I get the same error.

Fatal error: Call to a member function fetch_object() on a non-object in /index.php on line 167

Thanks again

What is the result of pritaeas suggestion print_r($result) at line 19 ?

The error tell you that $result is not an object so you can try this :

while($row = $mysqli->fetch_object($result)){

Hi Pritaeas,

Thanks for your assistance

$result = $mysqli->query("SELECT * FROM $tableName LIMIT $start, $limit");
print_r($result);

I have added the above code and i have no output

I have also added the print_r on the below execution which is on line 7 also no output

$query = $mysqli->query("SELECT COUNT(*) as num FROM $tableName");
$total_pages = $query;
print_r($query);

Thanks
David

Hi Pritaeas, Melvita,

Thank you both for your perseverance.

@ Melvita I have changed the code to

while($row = $mysqli->fetch_object($result)){

As advised

Having checked the password info by removing 1 charactor from the used password I get the usual unable to connect to the db.

I have added error checking with no error showing

ini_set('display_errors','on');
error_reporting(E_ALL);

db error check line
`mysqli = new mysqli($dbhost, $dbuser, $dbpass,$dbname) or die ("Error connecting to database");

if ($mysqli->connect_errno){
    printf("Connection failed: %s\n", $mysqli->connect_error);
    exit();
    }`

I changed mysql on line 11 as it is depreciated to
$page = mysqli_escape_string($_GET['page']); and I get 2 additional errors relating to this change

Warning: mysqli_escape_string() expects exactly 2 parameters, 1 given in /index.php on line 11

Notice: Use of undefined constant num - assumed 'num' in /index.php on line 9

Notice: Undefined index: page in /index.php on line 11

Fatal error: Call to undefined method mysqli::fetch_object() in /index.php on line 107

Thanks again

David
