I have posted this yesterday, I didn't get the the answers that could solve my problem but I got some pretty good ideas anyhow. This code retrieves the associated row from the db and translates it into PHP array so I could display it as a profile info. Here's my current code:
Query:
<?php
require 'includes/constants.php';
class newMysql {
private $conn;
function __construct() {
$conn = mysql_connect(DB_SERVER_USERS, DB_USER_USERS, DB_PASSWORD_USERS, DB_NAME_USERS);
if(!$conn) die('There was a problem connecting to the database.');
}
function get_profile(mysql_escape_string($lname)) {
$query = "SELECT * FROM members WHERE lname = '".$lname."' ";
$registerquery = mysql_query($query);
if($registerquery){
if (gettype($registerquery) == "resource") {
if (mysql_num_rows($result) != 0 ) {
while ($row = mysql_fetch_assoc($registerquery)) {
$profile[] = $row;
}
return $profile;
}
开发者_StackOverflow社区 }
if(gettype($registerquery) == "boolean") {
return "No array returned";
}
}
else return "Query not successful".$registerquery;
}
}
Display:
<?php
require 'classes/newMysql.php';
$mysql = new newMysql();
$profile = array();
$profile = $mysql->get_profile("lozano");
echo $profile;
Whatever I do, I get the message: "Query not successful". So the query does not return anything? It doesn't complain about db connection failure either. I tried the query directly from the CLI, it did return the expected row of data.
Any help pls...
when your query is not successfull use mysql_error
to know what happened.
http://php.net/manual/en/function.mysql-error.php
It should help you solve your problem quickly.
Edit :
It seems you don't select a specific database in your code. You should do
mysql_select_db($dbname, $conn);
after your connection, and before querying.
Does
function get_profile(mysql_escape_string($lname)) {
actually work?
I'd have expected a parse error... it certainly objects on my local 5.2.8 installation
function get_profile($lname) {
$lname = mysql_escape_string($lname)
You might want to try this :
<?php
require 'includes/constants.php';
class newMysql {
private $conn;
function __construct() {
$this->conn = mysql_connect(DB_SERVER_USERS, DB_USER_USERS, DB_PASSWORD_USERS, DB_NAME_USERS);
if(!$this->conn) die('There was a problem connecting to the database.');
}
function get_profile($lname) {
$query = "SELECT * FROM members WHERE lname = '".mysql_escape_string($lname)."' ";
$registerquery = mysql_query($query, $this->conn) or die(mysql_error());
if($registerquery){
if (gettype($registerquery) == "resource") {
if (mysql_num_rows($result) != 0 ) {
while ($row = mysql_fetch_assoc($registerquery)) {
$profile[] = $row;
}
return $profile;
}
}
if(gettype($registerquery) == "boolean") {
return "No array returned";
}
}
else return "Query not successful".$registerquery;
}
}
Don't use the or die
construct I added in production though (better to log these errors and give a nice error message to your endusers).
