Closed 7 years ago.
I have this search with pagination, the search function is working fine and the pagination is also working fine but my real problem is that I don't know how to merge those two. Every time I try to search, the search result is showing but the pagination is not functioning normal. Please someone help me about this issue. I don't know where to start.
I have this code:

Pages will have URL like example.com/search/term/?page=2 (or example.com/search.php?term=xyz&page=2, doesn't matter if you redirect URLs or not).
In PHP then will be something like:
$pagelimit = 10; // records per page
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1; // set current page
And LIMIT with OFFSET in your SQL query:
$sql = "SELECT *
FROM municipality
WHERE province_id LIKE '%$search_term%'
LIMIT " . ($page - 1) * $pagelimit . ", " . $pagelimit;
I am stuck on creating a dropdown list that is connected to another php page. I have used a sql query to list the staffNames but i need them to have the value of staffID. I have connected the page task7.php (which has a query that displays purchase information of a given staffID), so once the user clicks on a name then clicks submit, that persons order information should be displayed.Currently I am able to view the drop down list, select a name, but when i click submit the table only has field names with an empty table.

So this is the form, and it works fine, it calls all users from the database and displays them in tickbox fasion.
I can only assume my issue is in the exec script:
<?php
echo( "<pre>" );
print_r( $_POST );
echo( "</pre>" );
include ("config.php");
$tbl_name="members";
//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
die('Failed to connect to server: ' . mysql_error());
}
//Select database
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
die("Unable to select database");
}
//This gets all the other information from the form
$update = $_POST['otherdeets'];
$id = $_POST['userid'];
// Cycle through each member and check that it needs to be added to the db
$useruploadids = mysql_query( "SELECT member_id FROM members" );
while ($row = mysql_fetch_assoc($useruploadids))
{
// Check that the member was sent from the last form
if( isset( $_POST['userid_'.$row['member_id']] ) && $_POST['userid_'.$row['member_id']] == "y" )
{
// update data in mysql database
$sql="UPDATE $tbl_name SET otherdeets='$update' WHERE id='$id'";
$result=mysql_query($sql);
}
}
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='admin-welcome.php'>Admin Home</a>";
}
else {
echo "ERROR";
}
?>
When I run the script it simply says:
Array
(
[userid_1] => y
[otherdeets] => Blah Blah
[Submit] => Update
)
ERROR
Any idea what is wrong? Knowing my luck it would probabaly be a spelling mistake
Thank you
Hey your query is wrong there should be where condition with appropriate column name i.e. "member_id"
And one more thing
you are fetching the $id = $_POST['userid']; which is an error as there is no value exist with that key
rather you do in the if condition before doing the update query, i.e.
$id = $POST['userid'.$row['member_id']];
