hello all!!

How can I force the checkbox no to be erased?

I am using this code below but it is not working

<input name="topic1" type="checkbox" id="topic1" value="<?php if (isset($_POST['VB.NET'])) echo $_POST['VB.NET']; ?>" />

Hi.

I do not understand the question. What do you mean with erase the checkbox?

In order for a checkbox to be ticked, you don't set it's value, you set checked="checked". You might like to check out my tutorial on checkboxes and databases:

Sorry for not clarifiying!

 

I meant that for the field name: when I enter a name, and I click submit or accept, I need to see my form again, so the names are not erased because I put:

 

<input type="text" name="name" value="<?php if (isset($_POST['name'])) echo $_POST['name']; ?>">

 

I need to do the same for the checkboxes.

thx for the link, it is well organised and easy to understand;

but I did not find a solution to my problem :S

 

I am adding this script below for the fields, what should I add for the checkboxes?

value="<?php if (isset($_POST['name'])) echo $_POST['name']; ?>

Ok. So you know how to make a checkbox ticked by default, right?

 

You also know how to check to see if it was checked in the POST array, right?

 

So...What do you think you need to do?
