Update a MySQL database field data with HTML form and PHP

Question

So I am trying to update a database field using a html form and some PHP code, but I cannot get it to work, it throws no errors but does not update the field?, Im not sure if it

Answer 1

You need to use WHERE Condition whenever you try to update something to table.

Here's my code :

test.html

Name :  

updateform.php

To demonstrate I've created a database & table test_table with 3 field. (id,name,cost)

This is the structure of my table :

Before executing the above script, our table contains this datas

After executing the script, the name in second row changes from ramu to shiva since we specified cost as 500 in WHERE Condition.

$query = "UPDATE `test_table` SET `name` = '$name' WHERE `cost` = 500";
