help how to manipulate data using javascript

[codesearcher]

hi, I am new to javascript. I have just begun learning javascript in on some websites but I dont see answers for my questions about inserting, updating, deleting and selecting record using javascript and mysql.

there is this php and mysql where php can manipulate data from mysql database records.

but I would like to learn javascript manipulating records of mysql directly or thru php, like how to execute php using javascript to manipulate mysql records.

You can't use Javascript to access a database! Javascript is client-side whilst the database is on the server.

Nightwalker83, what I what to achieve is onclick of the button, I will call php that will manipulate the database record. Cant it be done?

If not, what alternative can I use?

[Nightwalker83]

Why do you want to use javascript since the user can disable it?

[codesearcher]

It was just my choice to use javascript. But I would like to know what you can advice me how to achieve what I want to do.

what I what to achieve is when I click a button, I will call php function that will manipulate the database record.

you don't need javascript to call php, just use the 'Action' attribute of the form and set its appropriate method.

Where will you get the data if you are not going to use a form? Your form should contain the Submit button that you can use to post those data and save them using php.

In todays day in age, there is absolutely nothing wrong with having a form save via an ajax call to a backend script. However, with something as mission critical as a save function, you should also allow for degradation by allowing the user to submit the form without javascript if it becomes disabled.

Also make sure that your javascript isn't the only thing validating your data -- always validate a second time on the server.
