All details of a single record of MySQL table in one page

Records from MySQL table We have seen how to display records of a mysql table here. Now we will learn how to display one record in a single page. This is required where full details of a record are to be shown in a page. Usually the records unique id is used to collect the details from the table. So same php page is used and the value of unique id of the record is taken as a variable. Before that links to different records are displayed and on click the full details are shown. So we will fist start with displaying a group of records with link to individual records.

Connecting database and executing Query

To manage data we have to connect to MySQL database and execute query to get our date. Here there are two ways to use PHP drivers to connect to MySQL and execute the functions for getting records.

One is using Portable Data Object ( PDO )
Second one is MySQLI ( MysQL Improved )

We will learn both here. We will first use PDO and at the end we will use MySQLI. You can use any one for your script.

Displaying Links to individual records

We will use our student table where we have added two more columns ( fields ) to store address and image. As we have more records so to restrict number of records we will display records of a particular class. The query is here.
select * from student where class='Four' order  by  id
Using the above query we will display the records by keeping them inside an html table. At the top of the script we will connect to MySQL database.
Here is the code.
<body >

require "config.php"; // connection string is here

////////Query & Data Display is here/////////

$q="select * from student where class='Four' order  by  id ";
echo "<table>";
foreach ($dbo->query($sql) as $row) {
echo "<tr><td><a href=details.php?id=$row[id]>$row[name]</a></td><td>$row[class]</td></tr>";
echo "</table>";
You can see we have used the name field to display a hyper link and by clicking that the individual record can be displayed in details.php page. We have formatted the hyper link to carry the student id in query string.
<a href=details.php?id=$row[id]>$row[name]</a>
Link with name value pair
The output of above code is here

Displaying individual records in page

Showing one record from MySQL table By clicking the hyper link the address bar will carry the student id to details.php page to use inside our query. But before using this student id we have to sanitize this data as it can be changed to carry out injection attack. There are different ways to do this but we will check if the data is numeric or not and exit the page execution if we found non-numeric value is stored in id variable. Here is the code to this part.
$id=$_GET['id'];        // Collecting data from query string
if(!is_numeric($id)){ // Checking data it is a number or not
echo "Data Error";
Now we can use this id value inside our query.
select * from student where id=:id
In above query we have collected the data for the individual record. Now we will display all the fields of the record like this.
NameKrish Star
AddressKrish Star_address
Here is the code for this.

<body >

require "config.php"; // database connection is here

//////Displaying Data/////////////
$id=$_GET['id'];        // Collecting data from query string
if(!is_numeric($id)){ // Checking data it is a number or not
echo "Data Error";    

$count=$dbo->prepare(select * from student where id=:id ");

echo " Success ";
$row = $count->fetch(PDO::FETCH_OBJ);

echo "<table>"; echo " <tr bgcolor='#f1f1f1'><td><b>Name</b></td><td>$row->name</td></tr> <tr><td><b>Class</b></td><td>$row->class</td></tr> <tr bgcolor='#f1f1f1'><td><b>Mark</b></td><td>$row->mark</td></tr> <tr><td><b>Address</b></td><td>$row->address</td></tr> <tr bgcolor='#f1f1f1'><td><b>Image</b></td><td>$row->img</td></tr> "; echo "</table>"; //////////////////// ?> </body> </html>

Displaying records using MySQLI functions

First we will display all records and then on user clicking of link the full details of the student can be displayed.
require "config.php"; // MySQL connection string

$count="SELECT name,id,class,mark,sex FROM student LIMIT 10";

if($stmt = $connection->query($count)){
echo "<table>";

while ($row = $stmt->fetch_assoc()) {
echo "<tr><td><a href=details.php?id=$row[id]>$row[name]</a></td>

echo "</table>";
echo $connection->error;

Displaying all details of single record

// Collecting data from query string
// Checking data it is a number or not
echo "Data Error";
// MySQL connection string
require "config.php"; 

$count="SELECT *  FROM student where id=?";

if($stmt = $connection->prepare($count)){

 $result = $stmt->get_result();
 echo "No of records : ".$result->num_rows."<br>";
 echo "<table>";
echo "<tr ><td><b>Name</b></td><td>$row->name</td></tr>
<tr ><td><b>Mark</b></td><td>$row->mark</td></tr>
<tr ><td><b>Image</b></td><td>$row->img</td></tr>
echo "</table>";
echo $connection->error;

Displaying Image stored in MySQL table

Usually images are stored in any folder or directory but the name of the image file is stored in a field so to display the photo we will format the image file name by using html img tag. Here is an example to display the photo in place of file name ( replace $row->img with this code ).
<img src=dir_name/$row->img>

Here is the dump of the student table ( with address and image column )

    how to link each data to each profile page using id


    hi can I ask what are the url names of the codes like index.php? I didn't work because I don't know what will I put when I save it. Thank you


    Each record can be linked by using userid or id and details of the profile can be shown as explained above

    select * from student where id=:id


    File names can be anything, you must match the links to the file names.
