I am learning PHP. I tried building a script that shows records from MySQL by pagination.
I set the code to show 1 record per page. There are 4 records or matches on the MySQL table for the recipient 'admin123'. I have logged-into this account.
And so, this pagination script should pull 4 records to show me. 1 record per page. Total 4 pages. It gives echo 2 results found (it should show 4). And then only shows 1 record on the page as expected. But, I do not see the pagination section. No links to the other pages are getting shown like this:
Page 1234.
I am confused now. Please take a look and let me know where I am going wrong.

Ive been working on this issue for some time now, basically, i have a table and at the end of row is a button that submits that rows batchID and Priority value to my .php that handles post requests. the problem comes when i hit submit it takes the batchID column from the last row regardless of which button is pressed. i have this exact same code running on another site which works as intended. when i inspect the network data being sent it shows that all the data in column batchID is being sent to upload.php, but i only need the corresponding batchID to be sent.
<?php
$con = mysqli_connect("localhost", "root", "", "production_management");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
require('databaseDetails.php');

I have a page that executes a query from a database. There are 5 columns, and I want the first and last column to be a sorting hyperlink. This is my code. I want to be able to click on column "price" or "course ID" to sort them by the category. When I click the link, nothing happens, but the ?sort=price shows on the url. I am fairly new to PHP and MySQL and I cannot find anything online. Thank you in advance.
<?php
require_once ('mysqli_connect.php');
//grab data from database
$course = "SELECT course.courseID, course.courseTitle, course.credit,
book.bookTitle, book.price, book.isbn13
FROM course
INNER JOIN coursebook ON course.courseID=coursebook.course
JOIN book ON coursebook.book=book.isbn13
ORDER BY course.courseID";
$course_response = mysqli_query($dbc, $course);
$isbn = "SELECT isbn13 FROM book";
$isbn_response = mysqli_query($dbc, $isbn);

You are not passing the get paramaters to the mysql query to order the results.
update your codes by following code,
<?php
require_once ('mysqli_connect.php');
//grab data from database
$order_by = null;
if($_GET){
switch($_GET['sort']){
case 'price' :
$order_by = 'ORDER BY book.price ASC';
break;
case 'course' ;
$order_by = 'ORDER BY course.courseID DESC';
break
}
}
$course = "SELECT course.courseID, course.courseTitle, course.credit,
book.bookTitle, book.price, book.isbn13
FROM course
INNER JOIN coursebook ON course.courseID=coursebook.course
JOIN book ON coursebook.book=book.isbn13 ";
$course .= (!is_null($order_by)) ? $order_by : "ORDER BY course.courseID ASC";
$course_response = mysqli_query($dbc, $course);
if(!$course_response){
die("Error in query: " . mysqli_error($dbc));
}
?>
<!DOCTYPE html>

<?php while($row = mysqli_fetch_array($course_response)){ ?>

I have a PHP page, that on clicking the submit button process a few MySQL queries.
in MySQL PHPMyAdmin the query works 100% and both queries execute. However, when in my PHP Code the queries do not execute.
Any help would be appreciated, I bet this is a simple one for decent PHP coders.
Thanks in advance Ryan.
My Code is:
<?php
mysql_connect("localhost", "hulamin_hulamin", "Hulamin2011")or die("cannot connect");
mysql_select_db("hulamin_loc")or die("cannot select DB");
$sql="SELECT `dispatcharea`,`customer`,`casenumber`,`weight` from loaddetails where loadid = 0 order by dispatcharea";
$result=mysql_query($sql);
$count=mysql_num_rows($result);
?>

Thanks again,

According to the PHP docs, mysql_query doesn't support multiple queries. PHPMyAdmin is probably separating the queries before executing them. Try splitting your query into two parts. (Also, the PHP docs say that you shouldn't end mysql_queries in semicolons, but it doesn't appear to hurt.)
I think that this is likely to be your problem
while($rows=mysql_fetch_array($result)){
Should be
while($rows=mysql_fetch_assoc($result)){
To refer to them as
echo $rows['dispatcharea'];
EDIT:
You also need to split both of your queries up in to two separate queries, because you cannot run two queries in one mysqli_query() tag.
You will need to split them as shown below:
// First update query
$sql1="update loaddetails set loadid= (select max(loadid)+1 from loadcounterid) where loadid=0";
// Second update query
$sql2="update loadcounterid set loadid= (select max(loadid) from loaddetails) where loadid>0";
// Run both queries independently
$final_query1 = mysql_query($sql1);
$final_query2 = mysql_query($sql2);
// Check for query success
if ($final_query1 && $final_query2)
{
// Success running the queries
}
else
{
// Unsuccessful running the queries
}
If you want to execute multiple queries at once, you can change over to using mysqli functions.
There is a mysqli function mysqli_multi_query() that can be used to execute multiple queries at once.
Please refer to:
http://php.net/manual/en/mysqli.multi-query.php
Here's a rough rewrite of the code using mysqli_multi_query() in an object oriented style:
<?php
$link = mysqli_connect('localhost', 'hulamin_hulamin', 'Hulamin2011', 'hulamin_loc');
$sql = "SELECT `dispatcharea`,`customer`,`casenumber`,`weight` from loaddetails where loadid = 0 order by dispatcharea";
$result = $link->query($sql);
$count = $result->num_rows($result);
?>

I thought I would just post my complete code that is now working. thanks to all who replied to my question, it is greatly appreciated. It is really awesome to be a part of this community that is so responsive.
My code is:

Try changing:
###Perform search
$searchResults = mysql_query($sql.$sql_with_limit);
To:
###Perform search
$searchResults = mysql_query($sql_with_limit);
I've noticed that the first condition does not work
if (empty($ss)) {
echo "please write your search words";
}
but the second does
else if ($num < 1) {
echo "not found any like ";
Full code:
<?php
require_once "conf.php";
$ss= $_POST["ss"];
$sql2=("SELECT * FROM student WHERE snum = $ss");
$rs2 = mysql_query($sql2) or die(mysql_error());
$num = mysql_num_rows($rs2);
if (empty($ss)) {
echo "please write your search words";
}
else if ($num < 1 ) {
echo "not found any like ";
}else {
$sql=("SELECT * FROM student WHERE snum = $ss ");
$rs = mysql_query($sql) or die(mysql_error());
while($data=mysql_fetch_array($rs)) {

Are you sure that $ss isset? i.e. there is a POST variable with the name ss. you could test it with.
if (empty($ss) || !isset($ss)) {
echo "please write your search words";
}
or test for it when you read in the post var
if ((!isset($_POST["ss"]) || (!is_numeric($_POST["ss"])))
{
$ss = 0;//empty considers 0 as been empty
}
else
{
$ss = $_POST["ss"];
}
ss looks to be a number too, so checking if it is numeric using is_numeric will help stop SQL errors, if for some reason it is not.
Use
if (!isset($ss)) {
echo "please write your search words";
}
instead of
if (empty($ss)) {
echo "please write your search words";
}
Try changing the condition to
if(empty($_POST['ss'])){ ... }
and continue using $_POST['ss'] instead of $ss.
BTW Always use error_reporting(E_ALL) when developing.
$sql=("SELECT * FROM student WHERE snum = $ss ");
Remove the brackets in the variables ($sql1 and $sql2) that have your query
It should be
$sql="SELECT * FROM student WHERE snum = $ss ";
I think that's why its telling you that you have an error near ...
