I'm trying to access a database table, this table is going to have 100+ records for which I would like to pick specific rows (through their unique id). Here is some of the php code I have...
<?php
function connect() {
$conn = new mysqli('localhost', 'root', 'pass', 'db') or die('There was a problem connecting to the db');
return $conn;
}
function get($conn) {
$stmt = $conn->prepare("SELECT * FROM camera") or die('There is a problem with the connection');
$stmt->execute();
$stmt->bind_result($id, $camera_id, $name, $location, $camera_status, $contact_name, $contact_phone);
$rows = array();
while($row = $stmt->fetch()) {
$item = array(
'id' => $id,
'camera_id' => $camera_id,
'name' => $name,
'location' => $location,
'camera_status' => $camera_status,
'contact_name' => $contact_name,
'contact_phone' => $contact_phone
);
$rows[] = $item;
}
return $rows;
}
$conn = connect();
$results = get($conn);
?>
There will be 9 results per page, these results have to be coded in manually. I am able to display all results in the database but I would like to be able to pick 9 unique results, display the contents of the row as well as offering a way to edit the entry. The unique identifier will be their $id.
What would be the easiest way to select these rows in php?
Thanks in advance!
J.
use limit
in query for specific rows like this example
SELECT * FROM camera limit 0,9
Use limits
$start= 0; $end=9; //you can make $start =10; $end=9; for next run and so on..
SELECT * FROM camera limit "'.$start.'","'.$end.'"
You can use limit
to select the lines you want after sorting by id with order by
. First limit 0, 9
then on the second load use limit 9,9
, and so forth.
Limit should be after where clause.
Syntax :
SELECT column_name(s)
FROM table_name
[WHERE]
LIMIT number;
I made the entire script load results dynamically (with foreach
loop) instead of having to manually add them. Originally I wanted to add the rows manually because the video streams will be limited to a per client basis, so I just added an extra database column to get around this issue.
I'm still limited to 9 feeds per page so I will be using the limit
feature for that, thanks for the help and feedback!
