[LadyA]

hi every body
I am working on web project and I want a simple code

I have made a drop down list in my HTML
and I want to save the selected value in a PHP variable
so I can insert it to my database is this is the correct way?

category <select  name="category_type"  > 
<option <?php if ($_POST['selectbox'] == 'Networks') echo '$selected="Networks"';?>> Networks</option>
 <option <?php if ($_POST['selectbox'] == 'Securty&systems') echo '$selected="Securty&systems"';?>>Securty&systems </option> 
<option <?php if ($_POST['selectbox'] == 'Software Develpments') echo '$selected="Software Develpments"';?>>Software Develpments</option> 
<option <?php if ($_POST['selectbox'] == 'Web&information') echo '$selected="Web&information"';?>>Web&information </option> </select> </br>

I cant use post because i don't have a database with category values

Please use code tags when posting code.

You question is unclear and vague so I don't know what it is you're actually trying to do.

But when you say:

I cant use post because i don't have a database with category values

That makes no sense because POST and GET have nothing to do with databases. They are merely a way of passing information from page to page.
