PHP - Mysql_query In Oop. Im New To This.
I am getting a "mysqli_query() expects parameter 1 to be mysqli, null given" error.
the code I am using is below but simplified. connect() does connect to the database without throwing any errors but when I get down to query() I get the above error. public function connect() { mysqli_connect(self::DBHOST, self::DBUSER, self::DBPASS, self::DBNAME); } public function query($query) { mysqli_query(self::connect(), $query); } below is what I am using to call the function. I am not sure if I have to pass the $link in the query function too. I have tried but it didn't seem to do any better. $link = db::connect(); $query = "SELECT name FROM plugins"; db::query($query); I am sure this is something simple that I have overlooked but I am new to this and still learning. Thank you for any help you can provide. Similar TutorialsHi, why won't this work, there is no error messages so it gets to this point, but won't redirect??? (Obviously a lot is missed out here) $query = mysql_query("SELECT * FROM `users` WHERE `username`='$username'"); if ($username==$dbusername&&$password==$dbpassword) { $_SESSION['user'] = $username; while($row = mysql_fetch_array($query)){ $type = $row['Type']; if ($type=="0") { header("Location: chefpanel.php"); }else{ header("Location: restpanel.php"); } } } else $errors[] = 'Password Incorrect'; } else $errors[] = 'Username Incorrect'; OK So I have a quick question... how would I go about making a query like: mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password' AND key='$key' "); You see, theres an error: Quote You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' key='1234' LIMIT 1' at line 1 I know this is a simple issue, and I know you cant keep creating AND's inside the query, but how would I do it? I've never attempted to use more than one AND before, so its new to me even though I'm a experienced PHP Developer. Thanks in advance! Hey Guys, Im having problems with my code. What im trying to do is run a mysql query and show the results, but if the query returns no data, echo out "No incoming requests!" Here is my code: <? $check = "SELECT * FROM requests WHERE club='" . $_SESSION['club'] . "' AND team='" . $_SESSION['team'] . "' AND accepted='0'"; $result=mysql_query($check); if (mysql_num_rows($result) == 0) { while ($getinfo = mysql_fetch_array($result)) { $time = $getinfo["time"]; $who = $getinfo["player_name"]; $whofor = $getinfo["toplayfor"]; $from = $getinfo["team"]; $idp = $getinfo["player_id"]; echo "<a href='profile.php?id=".$idp."&team=".$from."'>".$who." </a><div style='float:right;'>(".$from.")</div><br />"; echo "<div style='margin-top: 2px;'></div>"; echo date('l, F jS, g:ia',$time); echo "<br /><div style='margin-top: 2px;'></div><a href='accept.php?playerid=".$idp."&toplayfor=".$whofor."'>Accept</a> | Decline"; echo "<div id='newsline'></div>"; } } else { echo 'No incoming requests'; } ?> Could someone help me out here? Thanks Heaps! Hey guys, I've been playing around with this open source php game, I'm having problems with the registration system. For some reason the script is echoing back that there is no password in the password fields.

Cheers I'm hoping someone can help me cos my hair's going white with this one. I'm trying to put together a script that acts as web-based interface to an SQL server. There are actually two parts, admin.htm and admin.php. The first part is just a form that passes login credentials to the PHP file. That part seems to work fine, but I'll post the source anyway: - Code: [Select] <!DOCTYPE HTML> <html lang="en"> <head> <title>SQL admin login</title> <meta charset="iso-8859-1" /> </head> <body> <form action="admin.php" method="post"> <label for="username">Username: -</label> <br /> <input type="text" name="username" id="username" /> <br /> <br /> <label for="password">Password: -</label> <br /> <input type="password" name="password" id="password" /> <br /> <br /> <label for="server">Server: -</label> <br /> <input type="text" name="server" id="server" /> <br /> <br /> <label for="database">Database: -</label> <br /> <input type="text" name="database" id="database" /> <br /> <br /> <input type="submit" value="Login" /> <input type="reset" value="Reset" /> </form> </body> </html> Following is the content of admin.php. By this point I can see the connection in MySQL Workbench, and when I submit the query 'SELECT * FROM subscribers' it's being stored in '$_POST['query']', but 'mysql_query($_POST['query'],$_SESSION['con']);' is returning nothing. There is definitely a record in that table, and the user I'm logging on with has permission to run the 'SELECT' command against this database, so I can't figure out why mysql_query(); is returning nothing: - Code: [Select] <!DOCTYPE HTML> <?php session_start(); if(!$_SESSION['con']) { if(!($_POST['username'] || $_POST['password'])) { if(!($_SESSION['username'] || $_SESSION['password'])) { $error="Username and password variables empty."; } } else { $_SESSION['username']=mysql_real_escape_string($_POST['username']); $_SESSION['password']=mysql_real_escape_string($_POST['password']); $_SESSION['server']=mysql_real_escape_string($_POST['server']); $_SESSION['database']=mysql_real_escape_string($_POST['database']); $_SESSION['con']=mysql_pconnect($_SESSION['server'],$_SESSION['username'],$_SESSION['password']); if(!$_SESSION['con']) { $error="Failed to connect to server."; } else { $database=mysql_select_db($_SESSION['database'],$_SESSION['con']); if(!$database) { $error="Failed to connect to database."; } } } } if(!$_POST['query']) { $error="No query submitted."; } else { $result=mysql_query($_POST['query'],$_SESSION['con']); if(!$result) { $error="Query returned nothing."; } } ?> <html lang="en"> <head> <title>SQL admin interface</title> <meta charset="iso-8859-1" /> </head> <body> <form action="admin.php" method="post"> <textarea name="query" rows="10" cols="50">SELECT * FROM subscribers</textarea> <br /> <br /> <input type="submit" value="Submit query" /> </form> <?php if($error) { echo $_POST['query']."<br /><br />".$result."<br /><br />".$error; die(); } else { while($row=mysql_fetch_assoc($result)) { echo $row['name']."

[/code] tags added. hey I am still little new in php can you help me in this one func.php function confirm_query($result_set){ if(!$result_set){ die(mysql_error()); } function get_subjects_all() { global $connection ; $sub_query = "SELECT * FROM subjects ORDER BY position ASC"; $subject_query = mysql_query($sub_query,$connection); confirm_query($subject_query) ; return $subject_query; } function get_pages_all($subject_id) { global $connection; $query = "SELECT * FROM pages WHERE subject_id = '$subject_id' ORDER BY position ASC"; $page_set = mysql_query($query, $connection); confirm_query($page_set); return $page_set; } test.php require_once("config.php"); require_once("func.php"); $subject_query = get_subjects_all(); while($subject = mysql_fetch_array($subject_query)) { echo "<a href= \"test.php?subj=" . urlencode($subject["id"]) .

' but not worked but if i changed $subject_id to a number it work and read the data from the table thanks in advanced . I've got a very simple script that records IP address of every page view. Here is the script: $ip = $_SERVER['REMOTE_ADDR']; $query = "INSERT INTO tracking VALUES ('', '1', '$ip')"; echo $query; echo ("<hr>"); if (mysql_query($query)) { echo ("INSERT OK"); } else { echo ("INSERT failed"); } FYI: the 1st value is "auto_increment" in the DB, therefore blank ('') in the query string, and the 2nd value "1" is just for the page number 1, as this script will be on other pages, with different numbers. Now, when I go to this page, it outputs the query, and hr, and then "INSERT failed" and sure enough, no record gets added to the DB. The strangest thing is, is that when I copy the query that the page shows, and paste it into mysqlPHPadmin's "SQL" section and run it, it executes fine, and a record gets added to the DB, however the page is unable to do that. Any ideas? PS: the connection (which I didn't paste in here) is fine, that's definitely not the problem.

Issue i'm having is that first it wasn't entering any data into my database then eventual through much troubleshooting I figured out that if I add more then 10 variables in my INSERT INTO query it wont work. Ten or less and it works perfect. I CAN NOT figure this out?! Note, at the bottom of the php script I have the script that I would like to work, commented out, and the script that is currently working, active. You can see it only has 10 working entries.

However, I know this is doable via jQuery / Ajax ... all i need is a proper code that actually works. Hi, I am a little confused on the difference the mysql_fetch_array and mysql_query? Whats the difference between those two?

The Problem is, I have read all the tutorials and everything and successfully accomplished this at other places so I don't know what the issue is.

Thanks for the help in advance! Edited to Fix Stupid Mistakes Hi everyone, On my website people can add their domain names in a text box. I then use a foreach to validate each domain the text box. The code is similar to: foreach($lines as $line){ $count_query = mysql_query("SELECT * FROM domains WHERE domain='$line'"); $count = mysql_num_rows($count_query); if ($count > 0){ $error[] = $line . " already exists!<br />"; } } I was wondering if anybody knows a way to use the mysql_query outside of the foreach loop, as if the person has entered 100 domains for example, thats 100 queries accessing my database. Im not too sure if its possible or not. Anybody have any ideas? Many thanks This works: $result = mysql_query("SELECT * FROM mydatabase WHERE username = 'billybob'"); This does not: $user = "billybob" $result = mysql_query("SELECT * FROM mydatabase WHERE username = $user"); Shouldn't these be identical? If I echo $user, I get, of course, "billybob", so does anyone know why the variable isn't working in the query itself? |
