PHP/MySQL Checkbox Form Question

Amanda_Ryan

I am very new to PHP/MySQL and to my great delight (and utter amazement!) I have managed to create a form containing a list of checkboxes generated from a MySQL database.

I have a "Submit" button at the bottom of the form which reloads the same page and uses the $_POST array to calculate a number which is now displayed at the top.

The improvement I'm trying to make to this page is to keep the boxes checked when the page is reloaded / form submitted so that the user can see what they selected.

I have a sneaky feeling this might be a JavaScript/onChange issue but I thought I'd check here first in case there's a PHP method of "not resetting a form on POST" or something.
😕

In case you need an example:

If I understand what you are wanting to do, you can set up each checkbox input like this (obviously replacing "sample" with the name of your checkbox and the value "Yes" with the value of that particular input):

<input <?php if (!(strcmp($_POST['sample'],"Yes"))) {echo "checked";} ?> name="sample" type="checkbox" id="sample" value="Yes">

Hope this helps!
