ok, when i started to learn about php, i wanted to know how i can put that data from a HTML form into mysql database. it wasn't easy to lear because there was so much stuff i need to know. so to help you, make sure you have these things so you will be able to learn my tutorial here on how to insert data into mysql from a PHP web form.

1. Knowledge of HTML (average knowledge)
2. Knowldege of PHP (average knowledge)
3. Knowledge of Mysql (average knowledge)
4. Have a website with PHP (if you don't have a PHP/mysql website, visit our friends at www.webune.com and signup for a PHP/mysql web hosting plan)


now that you have at least all the four points above, its time to show you how you can insert the data.

Step 1

ok, i will give you a short tutorial...

In this example, lets say i want to collect data from a user. For the purpose of this tutorial guide, i only need the user's name and their email address. so i only need two text fields. one is user_name and the second one is user_email. so this is how the form would look like in HTML:

this is how the form will look like:

---

Name:

Email:

---

FORM HTMLCODE

---

STEP 2

the next step would be to have php check if the form has been submited or not. if the form has been submitted..

the way you can tell if a form has been submitted is to check if our submit button has a value.. if you look closely in our form html. i have this

HTML CODE

as you can see, the name of the submit button is called "Submit" so that the string variable name we can find out if its true or false. to check if the form is submitted i will use the if else operator in php

PHP CODE

Step 3

ok, on step three, you will need to have the following information, if you dont have this information,,, you will not be able to continue on with this tutorial

1. hostname (usually localhost)
2. database user name (if you don't have this contact your host company)
3. database user password (if you don't have this contact your host company)
4. database name (if you don't have this contact your host company)
5. database table name (you create this. you can create a table in phpmyadmin)

if you dont have all these requirements contact you webhosting company.

if you are a Webune customer, contact us and we will be glad to provide this information for you.

Step 4

the next step involves in us creating some tables in the mysql database.

so login to your database using phpmyadmin. if you are a webune customer, login to the control panel and click on the phpmyadmin link, you will need to login to the database in step 3.

once you are in phpmyadmin click on the SQL tab and copy and past this sql dump into the text area:



this will create a table called user_info in your database, this is where we will enter the information from the form. as you can see, we created two fields, one called user_name and the other one called user_email



its should look something like this on your phpmyadmin

---

now its time to put the whole thing together.. we wrote up this simple script to show you how you can add. we made this script simple so that you can hack it, modify it or do whatever you want with it so you can practice and how how it all works. one this we ask is that please dont remove the www.webune.com link - we would appreciate it if you dont.

so open your favorite text editor. if you have windows like i do, im using windows xp, open a blank notepad and copy and paste the following php code into it:

webune.php

Now make sure to change the mysql connections settings. so for example, i have these settings. NOTE: this are fake, so make sure to change them, otherwise, this script will error out because it cant connect to the database.

$hostname = "localhost";
$db_user = "webune_user";
$db_password = "mypassword";
$database = "database";
$db_table = "user_info";

as you can see on my example, my hostname is localhost
my database username is webune_user
the password for my database is mypassword my database is database
and my database table is user_info

so now that you have changed these setting to your database credentials, save the notepad file as webune.php

now upload to your php website and open it with your browser, enter the information and once you get a sucess message, the information was entered into the datase.

---

i tested and it works. if you are a webune customer, you should not have any problems, since this test is done on our servers

here is how the form looks like in my firefox browser when i open webune.php


and when i submit the form with my name and email address i get this


now when i go to my phpmyadmin, i can confirm that the information i've entered on the form, was inserted into my database


NOTE: you should not by any means deploy this code in a real production website, as there are many security issues, like sql injection. the purpose of this tutorial is to give you an idea on how the process of getting information from your users and storing it in a database so you can later diplay it or use it with your web applications. if you are not sure what i mean by slq injection, you can find lots of resources on this website or google it and you will find. for example you can google this string:

done..

i hope this helps you

remember if you need php web hosting

webune has the right service for you

UPDATE:::
today we created a video following these steps and how it works for beginners:



UPDATE 2-19-2012 = I know some of you have criticize me because my grammar is not so good. I must apologize, English is my second language, but i am trying very hard to share what i know with everyone from around the world and English and Spanish are the most spoken languages spoken in the free world. so i wrote this tutorial in Spanish and in English. I am from the country of El Salvador. Our national language is Spanish, so i hope you understand. :)
