how to insert data in mysql( wamp) database through php?

Solution 1
There is an extra comma (,) in your SQL at the end. The correct one would be -
$sql = "INSERT INTO student_info(student_id, student_name, semester, section) VALUES('".$post_id."', '".$post_name."', '".$post_semester."', '".$post_section."')";
I was also able to see error 'Unable to Post' with your current code so that is working fine.
Solution 2
Try;
<?php
if(isset($_POST['id']) && isset($_POST['name']) && isset($_POST['semester']) && isset($_POST['section'])){
$post_id = $_POST['id'];
$post_name = $_POST['name'];
$post_semester = $_POST['semester'];
$post_section = $_POST['section'];
$link = new mysqli('localhost','root','','registration');
if($link->connect_error)
die('connection error: '.$link->connect_error);
$sql = "INSERT INTO student_info(student_id, student_name, semester, section) VALUES('$post_id', '$post_name', '$post_semester', '$post_section')";
//echo $sql;
$result = $link->query($sql);
if($result){
echo 'Successfully posted';
}else{
echo 'Unable to post';
}
$link->close();
die();
}
?>

I have tried many times, connection is successful, but I can not insert the data please help me.
Following is my code, I have just added an if check, to see if the query does't adds any data to the database then it should give some kind of indication so its saying unable to post. When I see in database table from wamp database, no data is inserted or added to the table, please help me it will be much appreciated. thanks.
<?php if(isset($_POST['id']) && isset($_POST['name']) && isset($_POST['semester']) && isset($_POST['section'])): $post_id = $_POST['id']; $post_name = $_POST['name']; $post_semester = $_POST['semester']; $post_section = $_POST['section']; $link = new mysqli('localhost','root','','registration'); if($link->connect_error) die('connection error: '.$link->connect_error); $sql = "INSERT INTO student_info(student_id, student_name, semester, section) VALUES('".$post_id."', '".$post_name."', '".$post_semester."', '".$post_section."',)"; //echo $sql; $result = $link->query($sql); if($result > 0): echo 'Successfully posted'; else: echo 'Unable to post'; endif; $link->close(); die(); endif; ?> <!DOCTYPE html> <html> <head> </head> <body> <h1>Student Registration</h1> <form action="add.php" method="post"> Student ID : <input type="text" name="id"/><br><br> Student Name : <input type="text" name="name"/><br><br> Semester : <input type="text" name="semester"/><br><br> Section : <input type="text" name="section"/><br><br> <input type="submit" value="create"/> </form> </body> </html>

Shadow over 8 yearsinsert echo $link->error; after the unable to post line and share the error message with us. Are you sure that the id field is to be populated manually?

e4c5 over 8 yearsThe whole purpose of deprecating mysql and asking people to use mysqli is to avoid this kind of query: "INSERT INTO student_info(student_id, student_name, semester, section) VALUES('".$post_id."', '".$post_name."', '".$post_semester."', '".$post_section."',)";

Masivuye Cokile about 7 yearsEven though your answer is correct, but however an answer is not just an answer by a code, you should also explain why he's code did not work, and why is yours working.
