Der er bare det problem at det jo meget gerne skal hænge sammen med noget mysql. Det hved jeg ikke hvordan man gør. Og så har jeg læst på www.webhosting.dk suport side at hvis jeg sætter denne kode end:
<?php
$host="webhotel1.webhosting.dk";
$user="mysqllogin";
$passwordsql="mysqlpassword";
$database="www.mitdomain.dk";
$sql_statement="insert into mintabel (navn,efternavn) VALUES ('testnavn','testefternavn')";
$linkId=mysql_connect($host,$user,$passwordsql);
$result=mysql_db_query($database,$sql_statement,$linkId);
//
// hent dem igen
//
$sql_statement="select navn,efternavn from mintabel where navn='testnavn' and adresse='testefternavn' ";
$linkId=mysql_connect($host,$user,$passwordsql);
$result=mysql_db_query($database,$sql_statement,$linkId);
$row = mysql_fetch_array($result);
$navn=$row["navn"];
$efternavn=$row["efternavn"];
mysql_close;
?>
Vil du oprette forbindelse med mysql sådan at du vil køre på deres server og ikke min computer.
JEg kan bare ikke få det til at hænge helt sammen nogen der vil hjælpe mig. I kunne også skrive til: mik_fck@otmail.com
