Question
How to initiate sql query by selecting a check box ?
I have a list of checkboxes. Near each of them there is an icon of vegetable or fruit.
Now when I select one of this checkbox (for example : tomato ) , all the nutritional values for the chosen food will be selected from the database and will be presented one near one in a separate cell.
So in this way , i'm able to select several kind of foods and all their attached nutritional values
will appear immediately.
Is there a way to initiate a select query by selecting a check box from the PHP file ?
