If you get this error: Call to a member function fetch_assoc() on a non-object in … , it means that you have an error in your mysql syntax. Ja jums tas error: Call to locekļa funkciju fetch_assoc () par bez objektu ... tas nozīmē, ka jums ir kļūda jūsu mysql sintaksi. Supposing that $mysqli is your database connection object, put echo $mysqli->error; just before the line you're getting the error on. Pieņemot, ka $ mysqli ir jūsu datu bāzes savienojuma objektu nodot echo $ mysqli-> error, vienkārši pirms līniju saņemat kļūdu.

$mysqli=new mysqli(HOST,USER,PASS,DB); $ mysqli = new mysqli (HOST, USER, PASS, DB);
$mQuery=$mysqli->query('select `data` from `this_table` where `id`=1'); $ mQuery = $ mysqli-> query ( "izvēlieties" datu `no` this_table `ja` id `= 1 ');
echo $mysqli->error; //echoes that column `data` does not exist in table `this_table` echo $ mysqli-> error; / / atbalsis, ka kolonna "dati" neeksistē tabulā `this_table`
$row=$mQuery->fetch_assoc(); //gives error as the column `data` is in table `that_table`, not in table `this_table` $ row = $ mQuery-> fetch_assoc (); / / dod kļūdu kolonna "dati" ir tabula `that_table", nevis tabulā `this_table`
$mysqli->close(); $ mysqli-> Close ();
