Updating database using php

To update a record in any table it is required to locate that record by using a conditional clause.

Below example uses primary key to match a record in employee table.

We can do this by learning object-oriented programming (OOP) in PHP.

Object-oriented programming (OOP) is a programming language model organized around objects rather than "actions" and data rather than logic. To learn more, we created the next tutorial just for you!

Last week I explained how to create a link for each record to point to your update script.

This code assumes you are connected to a My SQL database which has a table with Names and Emails.Data can be updated into My SQL tables by executing SQL UPDATE statement through PHP function mysql_query.Below is a simple example to update records into employee table.Please make sure that, your variable not having values with qoutes ( ' ), May be the query is breaking somewhere.echo the query and try to execute in phpmyadmin itself. $sql = "UPDATE anstalld SET mandag = '$mandag', tisdag = '$tisdag', onsdag = '$onsdag', torsdag = '$torsdag', fredag = '$fredag' WHERE namn = '$namn'"; $retval = mysql_query( $sql, $conn ); //execute your query $sql = "UPDATE anstalld SET mandag = '.$mandag.', tisdag = '.$tisdag.', onsdag = '.$onsdag.', torsdag = '.$torsdag.', fredag = '.$fredag.' WHERE namn = '.$namn.'"; $retval = mysqli_query( $conn, $sql ); //execute your query if Your data is being updated in your database but not in your table its because when you will click on update button, the request is made to the same file.

Using this you can then create the update script, which will actually have two sections to it.
