Assuming that you echo $registration_form, what you describe as happening doesn't make sense since the registration form action is obviously student_records.php.  I wonder if there's a logic flaw in code we're not seeing here?

I think things should be clear to you now :) Here's the full coding :

[code]
<?php

if (isset($_POST['students_x'])){
$students = "<form method='post' action='student.php' name='students_form'>
<table border='0'>
<tr><td><input type='image' src='images/addstudent.gif' name='addstudent'></td></tr>
<tr><td><input type='image' src='images/editstudent.gif' name='editstudent'></td></tr>
<tr><td><input type='image' src='images/deletestudent.gif' name=deletestudent'></td></tr>
<tr><td><input type='image' src='images/viewallstudents.gif' name='viewallstudent'></td></tr>
</table>
</form>";
}

if (isset($_POST['addstudent_x'])) {
$registration_form = "<form method=\"post\" action=\"student_records.php\" name='registration_form'>
<table border='0' align='center' cellspacing='8' cellpadding='2'>
<tr><td>ID :</td><td><input type='text' name='id' size='1'></td></tr>
<tr><td>Name :</td><td><input type='text' name='name'></td></tr>
<tr><td>Father's Name :</td><td><input type='text' name='father_name'></td></tr>
<tr><td>Gender :</td><td>Male<input type='radio' value='Male' name='gender'>
    Female<input type='radio' value='Female' name='gender'></td>
</tr>
<tr><td>Address :</td><td><input type='text' name='address' size='50'></td></tr>
<tr><td colspan='2' align='center'><input type='submit' name='submit'></td></tr>
</table>
</form>";
}

if (isset($_POST['submit_registration_x'])){
include "connection.php";
$table_name = "registration";
$sql = "INSERT INTO $table_name (id, name, father_name, gender, address)
VALUES ('$_POST[id]', '$_POST[name]', '$_POST[father_name]', '$_POST[gender]', '$_POST[address]')";
$result = @mysql_query($sql, $connection) or die (mysql_error());
$sql = "SELECT * from $table_name";
$result = mysql_query($sql, $connection) or die (mysql_error());
echo "<form method='post' action='student.php' name='student_records'>
  <table border='1' cellspacing='4' cellpadding='2' align='center'>
  <tr><th>ID</th><th>Name</th><th>Father's Name</th><th>Gender</th><th>Address</th></tr>";
// $i=0;
while($row = mysql_fetch_array($result)){
$id = $row['id'];
$name = $row['name'];
$father_name = $row['father_name'];
$gender = $row['gender'];
$address = $row['address'];
$student_records[$i] = "<tr><td>$id</td><td>$name</td><td>$father_name</td><td>$gender</td><td>$address</td></tr>";
// $i++;
}
echo "</table></form>";
}

?>

From looking at your registration form, I can not see a submit button called 'submit_registration_x' which you check further down with another if statement which looks like it enters a new student into the database.  Try renaming the submit button of the registration form to 'submit_registration_x'.

Also it looks like your nesting html forms which is a no no.  In your HTML at the bottom you open a form and dont close it before echoing out the $registration_form and $students.
