  1. Hello. I have a page that displays data from a database based on pagination. All works well if I display all records (19 at the moment), but if I choose to view 8, or 10, or less than 19, I see duplicates of the same data, as well as new data not showing. How can I prevent duplications and have new date viewed without having to view all data? include("headsection.php"); include("nav.php"); if(isset($_GET['page'])) { $page = $_GET['page']; } else { $page = 1; } $num_per_page = 20; $start_from = ($page -1) * 2; $sql = "SELECT * FROM people ORDER BY id ASC LIMIT $start_from, $num_per_page"; $result = $con->query($sql); if( $result->num_rows > 0) { ?> <h1 class="center">List of all Users</h1> <table class="container3"> <tr> <td width="auto">PID</td> <td width="auto">Name</td> <td width="auto">Relationship</td> <td width="auto" class="center" colspan="3">Actions</td> </tr> <form action="" method="POST"> <?php while( $row = $result->fetch_assoc()){ echo "<input type='hidden' value='". $row['id']."' name='id'>"; //added echo "<tr>"; echo "<td class='success'>".$row['pid'] . "</td>"; echo "<td class='success'>".$row['name'] . "</td>"; echo "<td class='success'>".$row['relationship'] . "</td>"; echo "<td><a href='view.php?id=".$row['id']."' class='primary' title='view'>V</a></td>"; echo "<td><a href='edit.php?id=".$row['id']."' class='warning' title='edit'>E</a></td>"; echo "<td><a href='delete.php?id=".$row['id']."' class='danger' title='delete'>D</a></td>"; echo "</tr>"; } ?> </form> </table> <?php $pr_query = "SELECT * FROM people ORDER BY id"; $pr_result = $con->query($pr_query); $total_record = mysqli_num_rows($pr_result); //echo $total_record; $total_page = ceil($total_record/$num_per_page); echo "<h3 class='center'>Number of records in database: " . $total_record . "</h3>"; echo "<p class='center'>"; if ($page > 1 ){ echo "<a class='primary' href='users.php?page=".($page-1)."'>Previous</a>"; } for($i=1; $i<$total_page; $i++) { echo "<a class='primary' href='users.php?page=".$i."'>$i</a>"; } if ($i > $page ){ echo "<a class='primary' href='users.php?page=".($page+1)."'>Next</a>"; } echo "</p>"; ?> <br><br> <?php } else { echo "<br><br>No Record Found"; } ?> <?php include("footsection.php"); ?> As the site is localhosted, i am using mysqli - the site will not be online. Thanks in advance for any help.
  2. I cannot seem to figure this bit out. I'm trying to load data from an xml file depending on what the value of a url parameter is. I have an attribute set in my xml, but cannot seem to figure out how to go about this. I've looked at several examples of getting the attribute so I'm not sure where I am wrong since I haven't come across an example using url parameters to determine what data should be fetched. Here is what I have so far. An example of my xml file. There will be more records of piercing in this file. <piercings> <piercing id="default"> <title>Piercing Not Specified</title> <names>N/A</names> <gauge>0</gauge> <healing>0</healing> <risk>None</risk> <description>You must first choose a specific piercing from the menu to view information.</description> <aftercare>Aftercare tips will be available once you choose a specific piercing from the menu.</aftercare> <avoid>Things you should avoid will be listed once a specific piercing has been chosen.</avoid> <img>http://via.placeholder.com/350/000000/676767?text=Not%20Specified</img> <additionalimgs> <additionalimg>http://via.placeholder.com/350/000000/676767?text=Not%20Specified</additionalimg> </additionalimgs> </piercing> <piercing id="incomplete"> <title>Listing Incomplete</title> <names>N/A</names> <gauge>0</gauge> <healing>0</healing> <risk>None</risk> <description>The listing for this piercing is incomplete. Once completed the data will appear on this page. Please check back later.</description> <aftercare>Aftercare tips will be available once you the listing is complete.</aftercare> <avoid>Things you should avoid will be listed once the listing is complete.</avoid> <img>http://via.placeholder.com/350/000000/676767?text=Incomplete</img> <additionalimgs> <additionalimg>http://via.placeholder.com/350/000000/676767?text=Incomplete</additionalimg> </additionalimgs> </piercing> <piercing id="antieyebrow"> <title>Anti-Eyebrow</title> <names>Anti-Eyebrow, Teardrop</names> <gauge>16</gauge> <healing>6 - 8</healing> <risk>Rejection/Migration, Scarring</risk> <description>The anti-eyebrow piercing is located on the upper side of the cheek bone right below the orbital socket of the eye. This piercing is most commonly pierced using a 16 gauge curved barbell or custom bent jewelry. This piercing may also be referred to as a teardrop piercing.</description> <aftercare>It is recommended with this piercing to clean twice a day using saline solution or antibacterial soap. Do not overclean. Irritation from overcleaning can result in migration of the piercing. </aftercare> <avoid>Using rubbing alchohol as a cleaner. Changing the jewelry for atleast 3 weeks although recommended to wait until the piercing is fully healed. Pools/hot tubs especially those with chemical cleaners in them. Swimming holes, creeks, rivers, etc. due to bacterial exposure risk.</avoid> <img>http://jessetoxik.com/img/display/stock/antieyebrow_default.jpg</img> <additionalimgs> <additionalimg>http://jessetoxik.com/img/thumb/stock/antieyebrow_1.jpg</additionalimg> <additionalimg>http://jessetoxik.com/img/thumb/stock/antieyebrow_2.jpg</additionalimg> <additionalimg>http://jessetoxik.com/img/thumb/stock/antieyebrow_3.jpg</additionalimg> </additionalimgs> </piercing> </piercings> So for this one I am trying to pull all of the data for the piercing with the attribute of id="antieyebrow". Here is what I tried to retrieve that. URL: http://example.com/piercing.php?location=antieyebrow. if (file_exists($_SERVER['DOCUMENT_ROOT'].'/info/piercing/piercings.xml')) { $piercingxml = simplexml_load_file($_SERVER['DOCUMENT_ROOT'].'/info/piercing/piercings.xml'); $location = $_GET['location']; $piercingid = $piercingxml['id']; } else { $piercingxml = simplexml_load_file($_SERVER['DOCUMENT_ROOT'].'/info/piercing/default.xml'); $location = "default"; } And finally to display the data onto the page: echo $piercingxml->$piercingid[$location]->title; So far nothing from the file is being displayed. How do I accomplish this? Any help as to where I went wrong would be greatly appreciated.
  3. Folks, I found this piece of code on my notes. Cannot remember where I grabbed it from. It is supposed to fetch a page and grab it's meta details and display them on screen. Question is: What is this error I am getting ? Fatal error: Uncaught TypeError: DOMDocument::loadHTML() expects parameter 1 to be string, boolean given in C:\xampp\htdocs\curl\filter.php:31 Stack trace: #0 C:\xampp\htdocs\curl\filter.php(31): DOMDocument->loadHTML(false) #1 {main} thrown in C:\xampp\htdocs\curl\filter.php on line 31 <?php /* ERROR HANDLING */ declare(strict_types=1); ini_set('display_errors', '1'); ini_set('display_startup_errors', '1'); error_reporting(E_ALL); mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); function file_get_contents_curl($url) { $ch = curl_init(); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); $data = curl_exec($ch); curl_close($ch); return $data; } $html = file_get_contents_curl("https://www.google.com/search?q=dirty+harry&oq=dirty+harry&aqs=chrome..69i57.2604j0j7&sourceid=chrome&ie=UTF-8"); //parsing begins here: $doc = new DOMDocument(); @$doc->loadHTML($html); $nodes = $doc->getElementsByTagName('title'); //get and display what you need: $title = $nodes->item(0)->nodeValue; $metas = $doc->getElementsByTagName('meta'); for ($i = 0; $i < $metas->length; $i++) { $meta = $metas->item($i); if($meta->getAttribute('name') == 'description') $description = $meta->getAttribute('content'); if($meta->getAttribute('name') == 'keywords') $keywords = $meta->getAttribute('content'); } echo "Title: $title".

  4. Hello. I am using a form to send data to my database but when I submit the form, the data is not shown on the database. I am connected to the database so I don't think the problem lies there. Also, I have a redirect option via 'Location:' which also works. I am following online examples for the php. This is the PHP I am using: <?php include("dbcon/database-conn.php"); if (!empty($_POST)) #($_SERVER["REQUEST_METHOD"] == "POST") { $pagelinks = $_POST['pagelinks']; $title = $_POST['title']; $asideleft = $_POST['asideleft']; $body = $_POST['body']; $asideright = $_POST['asideright']; $sourceref = $_POST['sourceref']; $sourceimg = $_POST['sourceimg']; $q = "INSERT INTO pages (pagelinks) VALUES ('$_POST[pagelinks]')"; if ($_POST["add_record"]){ header('location:index.php'); exit(); } } ?> The form 'name' values match. As you can see I have tried two methods of 'Post' but neither seem to work. I would like to point out that this is an offline, local test and that I am aware that I am not using real_escape_strings, but I will, once I get the code to work. Also, I am aware of PDO, which I have tried but it is too complex, for me to solve right now. I am familiar with mysqli (including OOP), but am still learning.. I would be grateful if you can help solve my current issue. Thanks in advance for any help.
  5. I have a table like this. investment_id | investor_id | deposit | Date | Status I will be depositing funds into this table. For eg. If I am paying out 1000 investors at a time, 1000 rows will be added to this table. I might do this 100 times a day. That's 100,000 rows added in a day. Each deposit I do will be unique, even though it might be going to the same person multiple times. This could end up with million of rows. I am wondering if this is the correct way to do this or is there a better method?
