I am creating an Invitation Card app for my upcoming event which will be held. My code successfully inserts the data into mysql database named booking having table name data. But there is problem with retrieving. When I fill the form and submit, it saves data in db but generates nothing. It gives following error:
Fatal error: Call to a member function query() on resource in C:\xampp\htdocs\booking\index.php on line 44
Here is my code, please tell me how to resolve this issue. I shall be very thankful to you.

Change
$result = $conn->query($sql);
To
$result = mysql_query($sql);
For more info click here
I think you should be using mysql_query instead of $conn->query
I thin i spotted two errors in your code.
you should use
mysql_query($sql,$conn);
instead of (that was mentioned before)
$result = $conn->query($sql);
You missed a couple of opening php tags in your html table.
Try following code and let me know if it works.
if(! $conn){
die('Could not connect: ' . mysql_error());
}
if(! get_magic_quotes_gpc()){
$emp_name = addslashes($_POST['emp_name']);
$emp_fname = addslashes($_POST['emp_fname']);
$emp_cnic = addslashes($_POST['emp_cnic']);
$emp_address = addslashes($_POST['emp_address']);
} else {
$emp_name = addslashes($_POST['emp_name']);
$emp_fname = addslashes($_POST['emp_fname']);
$emp_cnic = addslashes($_POST['emp_cnic']);
$emp_address = addslashes($_POST['emp_address']);
}
$sql = "INSERT INTO data ". "(CNIC, Name, FatherName, PostalAddress) " .
"VALUES('$emp_cnic', '$emp_name', '$emp_fname', '$emp_address')";
mysql_select_db('booking');

I'm using easyPHP. I'm trying to update the records in my database but I keep getting <?php echo $btitle; ?> and <?php echo $bauthor; ?> written in the text boxes in my HTML form and data isn't updated but it does print "Updated data successfully".
Here's my form code:
<!DOCTYPE html>
<html>
<head>
<meta charset = "utf-8">
<title>Update Book</title>
</head>
<body>
<h1>Update Your Library</h1>
<form method = "post" action = "editBook.php">
<?php
$conn = mysql_connect ("localhost", "root", "");
$db = mysql_select_db ("library", $conn);
$query = "select * from Books where No = ". $_GET['bid'];
$result = mysql_query($query, $conn);
while ($row = mysql_fetch_assoc($result))
{
$bid = $row ['bid'];
$btitle = $row ['btitle'];
$bauthor = $row ['bauthor'];
}
mysql_close($conn);
?>
<table>
<input type="hidden" name="bid" size="5" value="<?php echo $bid;?>">
<tr>
<td>Title:</td>
<td><input type="text" name="btitle" size="100"value="<?php echo $btitle;?>"></td>
</tr>
<tr>
<td>Author:</td>
<td><input type="text" name="bauthor" size="100" value="<?php echo $bauthor;?>"></td>
</tr>
</table>
<p>
<input type="submit" value="Update">
</p>
</form>
</body>
</html>
<?php
$dbhost = '127.0.0.1';
$dbuser = 'root';
$dbpass = '';
$bid=$_POST['bid'];
$btitle=$_POST['btitle'];
$bauthor=$_POST['bauthor'];
$conn = mysql_connect($dbhost, $dbuser, $dbpass);

if(! $conn ) {

It seems like the files does not get parsed by PHP. The problem may be a filename extention not defined in configuration.
On other hand I see another problem which may raise when the first issue is solved. Viariables which hold information are out of scope. This will lead to empty answer.
When you read from database:
while ($row = mysql_fetch_assoc($result))
{
$bid = $row ['bid'];
$btitle = $row ['btitle'];
$bauthor = $row ['bauthor'];
}
those 3 variables are created in the while(){} scope and they do not exist outside of it. Just initialize them with empty string before the loop in the main scope:
$bid = $btitle = $bauthor = '';
while ($row = mysql_fetch_assoc($result))
{
$bid = $row ['bid'];
$btitle = $row ['btitle'];
$bauthor = $row ['bauthor'];
}
Try This ::
<!DOCTYPE html>
<html>
<head>
<meta charset = "utf-8">
<title>Update Book</title>
</head>
<body>
<h1>Update Your Library</h1>
<form method = "post" action = "save.php">
<?php
$conn = mysql_connect("localhost", "root", "");
$db = mysql_select_db("library", $conn);
$query = "select * from Books where No = " . $_GET['bid'];
$result = mysql_query($query, $conn);
while ($row = mysql_fetch_assoc($result))
{
$bid = $row['bid'];
$btitle = $row['btitle'];
$bauthor = $row['bauthor'];
}
?>
<table>
<input type="hidden" name="bid" size="5" value="<?php echo (isset($bid))?$bid:'';?>">
<tr><td>Title:</td><td><input type="text" name="btitle" size="100" value="<?php echo (isset($btitle))?$btitle:'';?>"></td></tr>
<tr><td>Author:</td><td><input type="text" name="bauthor" size="100" value="<?php echo (isset($bauthor))?$bauthor:'';?>"></td></tr>
</table>
<p><input type="submit" value="Update"></p>
</form>
</body>
</html>
<?php
mysql_close($conn);
?>
Problem
I would like to know how I would make the text at the top of the screen not show when connecting or searching the database. Below is a screenshot of what I am talking about.
Is it possible for it to not appear at all? Below is the code that connects to the database, as well as the code for the form below.
Code
The code to connect to the database:
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=***** port=*****
dbname=***** user=***** password=*****")
or die('Could not connect: ' . pg_last_error());
//collect
if(isset($_POST['search'])) {
$searchq = $_POST['search'];
// $searchq = preg_replace("#[^0-9a-z]#i"."".$searchq);
// Performing SQL query
$query = "SELECT vegan FROM enumbers WHERE code LIKE '%$searchq%'";
$ret = pg_query($dbconn, $query);
if(!$ret){
echo pg_last_error($dbconn);
exit;
}
$output = '';
while($row = pg_fetch_assoc($ret)){
$code = $row['code'];
print_r($row);
$name = $row['name'];
$type = $row['type'];
$vegan = $row['vegan'];
$output .= '<div> '.vegan.' ';
}
}
echo "Operation done successfully\n";
pg_close($dbconn);
?>
The code for the form:
<div id="tablebox">
<!-- Search bar -->
<p>Is It Vegan?</p>
<form name="form1" method="post" action="searchEnumbers.php">
<input name="search" type="text" size="30" maxlength="5" />
<input name="submit" type="submit" value="Search" />
</form>
<?php
print("$output");
?>
</div>
</div>
Just remove these two lines from your code
print_r($row);
.....
echo "Operation done successfully\n";
Try this one, Changes are noted via php comment (//)
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=***** port=*****
dbname=***** user=***** password=*****")
or die('Could not connect: ' . pg_last_error());
//collect
if(isset($_POST['search'])) {
$searchq = $_POST['search'];
// $searchq = preg_replace("#[^0-9a-z]#i"."".$searchq);
// Performing SQL query
$query = "SELECT vegan FROM enumbers WHERE code LIKE '%$searchq%'";
$ret = pg_query($dbconn, $query);
if(!$ret){
echo pg_last_error($dbconn);
exit;
}
$output = '';
while($row = pg_fetch_assoc($ret)){
$code = $row['code'];
//Commented 1
//print_r($row);
$name = $row['name'];
$type = $row['type'];
$vegan = $row['vegan'];
$output .= '<div> '.vegan.' ';
}
}
//Commented 2
//echo "Operation done successfully\n";
pg_close($dbconn);
?>
Problem
I am having a problem displaying the page after I compiled this code, but I cannot see what is wrong with it and I cannot debug due to it not appearing on the web.
PHP and PostgreSQL Code:
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=***** port=*****
dbname=***** user=***** password=*****")
or die('Could not connect: ' . pg_last_error());
//collect
if(isset($_POST['search'])) {
$searchq = $_POST['search'];
$searchq = preg_replace("#[^0-9a-z]#i"."".$searchq);
// Performing SQL query
$query = "SELECT * FROM enumbers WHERE code LIKE '%$searchq%'") or die ("could not search!");
$result = query($query);
if($result = 0){
$output = 'There is no such E-Number!'
}else{
while($row = mysql_fetch_array($query)) {
$code = $row['code'];
$name = $row['name'];
$type = $row['type'];
$vegan = $row['vegan'];
$output .= '<div> '.vegan.' ';
}
}
}
?>
The Form and Printing Code:
<div id="tablebox">
<!-- Search bar -->
<p>Is It Vegan?</p>
<form name="form1" method="post" action="searchEnumbers.php">
<input name="search" type="text" size="30" maxlength="5" />
<input name="submit" type="submit" value="Search" />
</form>
<?php
print("$output");
?>
</div>
Update
I think the problem might be I'm using some MySQL code, but I cannot tell If I am.
You are using mysql_fetch_array instead of postgres method. Please see the sample
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=**** port=****
dbname=**** user=**** password=****")
or die('Could not connect: ' . pg_last_error());
$output = '';
//collect
if(isset($_POST['search'])) {
$searchq = $_POST['search'];
// $searchq = preg_replace("#[^0-9a-z]#i"."".$searchq);
// Performing SQL query
$query = "SELECT * FROM enumbers WHERE code LIKE '%$searchq%'";
$ret = pg_query($dbconn, $query);
if(!$ret){
echo pg_last_error($dbconn);
exit;
}
$output = '';
while($row = pg_fetch_assoc($ret)){
$code = $row['code'];
print_r($row);
$name = $row['name'];
$type = $row['type'];
$vegan = $row['vegan'];
$output .= '<div> '.vegan.' ';
}
}
echo "Operation done successfully\n";
pg_close($dbconn);
?>

$dbLink = mysql_connect('localhost', 'root', 'root') or die(mysql_error());
mysql_select_db('cbrteh', $dbLink) or die(mysql_errno());

$sql = "INSERT INTO pucuk (gejala2) VALUES ({$gejala2})";
$dbLink = mysql_connect('localhost', 'root', 'root') or die(mysql_error());
mysql_select_db('cbrteh', $dbLink) or die(mysql_errno());
$result = mysql_query($sql);
if($result) {
echo "Record successfully inserted!";
}
else {
echo "Record not inserted! (". mysql_error() .")";
}
}
}
?>
</form>
but when i hit submit button it still has no effect
In while loop itself u can write insert query and send the option box value into the field u want,try it !
after a submit, your select option value will be in the $_POST[] variable under the name of your select. Namely, here "gejala2"
put your code in a form with method=POST and after submitting your form you will get all your new values in _POST array
for example
if(isset($_POST['submit']))
{
$var1=$_POST['select1'];
$var2=$_POST['select2'];
$var3=$_POST['select3'];
//then write update/insert query as your requirement
}
Try this
<?php
if(isset($_POST['gejala1'])) {
$gejala1 = $_POST['gejala1'];
$sql = "INSERT INTO pucuk (gejala1) VALUES ({$gejala2})";
$dbLink = mysql_connect('localhost', 'root', 'root') or die(mysql_error());
mysql_select_db('cbrteh', $dbLink) or die(mysql_errno());
$result = mysql_query($sql);
if($result) {
echo "Record successfully inserted!";
}
else {
echo "Record not inserted! (". mysql_error() .")";
}
}
if(isset($_POST['gejala2'])) {
$gejala2 = $_POST['gejala2'];
$sql = "INSERT INTO pucuk (gejala2) VALUES ({$gejala2})";
$dbLink = mysql_connect('localhost', 'root', 'root') or die(mysql_error());
mysql_select_db('cbrteh', $dbLink) or die(mysql_errno());
$result = mysql_query($sql);
if($result) {
echo "Record successfully inserted!";
}
else {
echo "Record not inserted! (". mysql_error() .")";
}
}
?>

Please kindly help me get rid of this error:
undefined index: id at edit.php.
I'm shocked by the terrible formating and not able to read the code.
But according to your description, you get undefined index: id because you either did not include the id field in the form, or you include it in the url but use $_POST instead of $_GET.
EDIT:
If this is exactly the code you have, then the problem should be the last few lines in proj.php.
include 'edit.php' is not the correct way to call edit page, but you should use a link tag which links to edit.php?id=some_id, just like you did with show.php
