PHP - Not Sure Why I Connect To Db But Cannot Create Row.
I have a simple form and I run my script without any errors. I click my btn and I would like to see my echo errors but no errors show up when I have no value in textboxes. I have tried if(isset($_Post["submit"])) and if($_SERVER["REQUEST_METHOD"] == "post") What I think is nether of there ifs are becoming valid on my btn click.
<?php
$nameerror = $twoerror = $errormsg = "";
// PHP Procedural MYSQLi
// connect to mysql database with phpmyadmin
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "test";
$connection = new mysqli($servername, $username, $password, $dbname);
//if(isset($_Post["submit"]))
if($_SERVER["REQUEST_METHOD"] == "post")
{
if(empty(trim($_Post["name"]))) {
$nameerror = "Name is required";
}
else {
$namesafe = mysqli_real_escape_string($connection, $_Post["name"]);
}
if(empty(trim($_Post["two"]))) {
$twoerror = "Two is required";
}
else {
$twosafe = mysqli_real_escape_string($connection, $_Post["two"]);
}
if($namesafe != "" && $twosafe != "") {
$sqlInsert = "INSERT INTO tester(name, two) " .
"VALUES('". $namesafe ."','". $twosafe ."')";
if(mysqli_query($connection, $sqlInsert)) {
echo "Successfully entered.";
} else {
echo "NOT successful error: " . $sqlInsert . "<br>" . mysqli_error($connection);
}
}
}
mysqli_close($connection);
?>
<?php
if(!$connection) {

Similar Tutorialsdefine("DB_HOST", "localhost"); Hello everyone, I am working on a form that is similar to a shopping cart system and I am thinking of creating a button that submits the checked value and saves them to a $_SESSION variable. And also a link that links to a cart.html that takes the values of a $_SESSION variable. I am have trouble figuring what tag/attribute should I use in order to achieve that.
Right now my code attached below submits the checked values to cart.html directly. However I want my submit button to save the checked box to a $_SESSION variable and STAY on the same page. And then I will implement a <a> to link to the cart.php.
I researched a little bit about this subject and I know it's somewhat related to ajax/jquery. I just wanted to know more about it from you guys. I appreciate your attention for reading the post and Thanks!
Below is the form that I currently have:
<form name= "finalForm" method="POST" action="cart.php">
<input type="Submit" name="finalSelected"/>
<?php foreach($FinalName as $key => $item) {?>
<tr>
<td><input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" />
<?php echo "$FinalID[$key] & $item";?>
</td>
</tr>
<?php } ;?>
Below is the code for cart.php
<?php
require ('connect_db.php');
if(isset($_POST['finalSelected']))
{
if(!empty($_POST['fSelected']))
{
$chosen = $_POST['fSelected'];
foreach ($chosen as $item)
echo "aID selected: $item </br>";
$delimit = implode(", ", $chosen);
print_r($delimit);
}
}
if(isset($delimit))
{
$cartSQL = "SELECT * from article where aID in ($delimit)";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
$aTitle[] = $row[ 'name' ];
}
}
?>
<table>
<?php if(isset($delimit)) {
$c=0; foreach($aTitle as $item) {?>
<tr>
<td>
<?php echo $aTitle[$c]; $c++;?>
</td>
</tr>
<?php }}?>
</table>
I'm trying to connect to two databases and I'm having problems with the following code. I googled to come up with this but can't figure out the errors I'm getting. Code: [Select] $connection="localhost"; $username="user"; $password="password"; $database1="dbone"; $database2="dbtwo"; $db1 = mysql_connect($connection,$username,$password) or die(mysql_error()); $sel1 = mysql_select_db($database1, $db1); $query1 = "SELECT * FROM TBLUSERS"; $result1 = mysql_query($query1, $db1); while($nt1 = mysql_fetch_array($result1, $db1)) { } $db2 = mysql_connect($connection,$username,$password) or die(mysql_error()); $sel2 = mysql_select_db($database2, $db2); $query2 = "SELECT * FROM TBLPD20101101"; $result2 = mysql_query($query2, $db2) or die(mysql_error()); while($nt2 = mysql_fetch_array($result2, $db2)) { } The error I get is Quote Warning: mysql_fetch_array() expects parameter 2 to be long, resource given in C:\xampp\htdocs\HighVisibility\DashBoard2.php on line 13 Warning: mysql_fetch_array() expects parameter 2 to be long, resource given in C:\xampp\htdocs\HighVisibility\DashBoard2.php on line 22 Hi, I have a script which uses a connect file but I am struggling to get files in other folders to read and for the "$loggedIn = checkLogin();" code to work. If I connect to the database within the same script it works straight away. If I change my password then I have to change every file but otherwise I cannot include the connect file as I have to link to it locally. So if the connect file is in: www.domain.co.uk/php/login/connect.php then www.domain.co.uk/php/login/index.php -- this works www.domain.co.uk/php/logout.php -- this doesn't regardless of how I link to the connect file. for some reason my database will not connect, here's the code: Code: [Select] <?php require("mstr_ref2.php"); function parseToXML($htmlStr) { $xmlStr=str_replace('<','<',$htmlStr); $xmlStr=str_replace('>','>',$xmlStr); $xmlStr=str_replace('"','"',$xmlStr); $xmlStr=str_replace("'",'&#39;',$xmlStr); $xmlStr=str_replace("&",'&',$xmlStr); return $xmlStr; } // Opens a connection to a MySQL server $connection=mysql_connect (localhost, $username, $password); if (!$connection) { die('Not connected : ' . mysql_error()); } // Set the active MySQL database $db_selected = mysql_select_db($database, $connection); if (!$db_selected) { die ('Can\'t use db : ' . mysql_error()); } // Select all the rows in the markers table $query = "SELECT * FROM markers WHERE 1"; $result = mysql_query($query); if (!$result) { die('Invalid query: ' . mysql_error()); } header("Content-type: text/xml"); // Start XML file, echo parent node echo '<markers>'; // Iterate through the rows, printing XML nodes for each while ($row = @mysql_fetch_assoc($result)){ // ADD TO XML DOCUMENT NODE echo '<marker '; echo 'name="' . parseToXML($row['name']) . '" '; echo 'address="' . parseToXML($row['address']) . '" '; echo 'lat="' . $row['lat'] . '" '; echo 'lng="' . $row['lng'] . '" '; echo 'type="' . $row['type'] . '" '; echo '/>'; } // End XML file echo '</markers>'; ?> I think there is something wrong with this line of code. Where it says 'locat host' im not too sure about that because im not connecting to a local host, so what can i put in there instead?i think that is the problem. Code: [Select] $connection=mysql_connect (localhost, $username, $password); This is the error I get: Code: [Select] Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'a2221438'@'localhost' (using password: NO) in /home/a2221438/public_html/map.php on line 44 Hey, I've had this problem for a couple days now, and haven't been able to work it out. I'm trying to connect to the Gamesurge IRC using PHP - though the code I am using times out and can't connect. I thought it was my code, however I have searched the web for working codes and they all *seem* to do the same basic thing as mine. So if anyone has any ideas as to why I am getting a timeout, I would appreciate it. The code I'm using. <?php error_reporting(E_ERROR); $cfg = array( "server" => "irc.gamesurge.net", "channel" => "#wiremod", "port" => 6667, "name" => "thetree PHP" ); echo "Connecting to " . $cfg["server"] . " on port " . $cfg["port"] . "<br/>"; $socket = fsockopen($cfg["server"], $cfg["port"], $errno, $errstr, 5); if (!$socket) { echo("Error[$errno]: $errstr...<br/>"); } else { echo "Socket connection successful..<br/>"; } fclose($socket); ?> Hosted file: http://joethetree.lil.org.uk/socket.php Thanks thetree Hi People. Thanks to everyone that helped me yesterday with my file that finally connected to the database. However, I have added a new field to my DB and now get further problems. Here is the error message I am getting after I added the "ppr" stuff to both files. Please could someone look at my code and tell me where I'm going wrong.

I looked through a lot of the facebook documentation, but I haven't been able to find any really good implementation suggestions. I just want basic functionality. HI, I'm running the next script from my local host and the production server, and Im getting different outputs. Anyone knows why am I getting that error from my localhost?

Edited November 26, 2020 by tirengarfio hi all First of all My client have dot net server on windows OS. They want to display some pages which are created by php. Is there any possibility to display like this. And How can i connect sql server using php on remote to retrieve data. Can any one tell me how can i do this. Thanks in advance Hello all, This is my first post in here, so go easy. I recently transferred my account from my local ISP to GoDaddy. And now my search criteria is not working. I am getting the follow error message on the page of my search box, instead of the graphics itself: Could not connect to MySQL:Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) I thought maybe this would be a simple error when I found out that GoDaddy does not use the "localhost" connect string. So I switched it to the local IP for GoDaddy still to no avail. I am lost after that. My PHP skills are limited. I was taught by a very advanced user who uses shortcuts and different strings self made for his ease. So looking online for solutions for the script was very hard(to me at least), because the lines of code do not match common scripts online. Is this a simple solution? Does the: global $dbc; @dbConnect(); function work with GoDaddy? Because I have seen maybe different ways to connect to a DB with PHP. Here's the script I am using to connect and extract results from the DB. Any and all help will be greatly appreciated. Thanks in advance.

I created a php and start coding, everything works just fine, but when I tried to connect to the mysql it gives me a blank page I inserted this code Code: [Select] <?php session_start(); $connect = mysql_connect('localhost','root', 'root'); or die(mysql_error()); $db = mysql_select_db('blog',$connect); $session_name = $_SESSION['uid']; ?> but then the whole page turns to be blank page , but when I excluded this, it works just fine. I don't get it cause my database/phpmyadmin connected just fine. Any help is much appreciated. Been trying to figure this out for hours. I am using this: $tags = @get_meta_tags($http["domain"]); Is there any way to tell if that function can not connect to the server for reasons such as server being down, or an invalid URL? hi i m new to php and i m working on a project in which i m configuring a mail server using Mdeamon 9.5.......

Is there a way for me to connect to a directory on a NAS server running a windows share from PHP. I can connect from the command line using mount, but I want the connect within my PHP script. Can this be done & if so how? |
