How do I store which of the php checkboxes are checked into the database. What kind of field do I need to create in the database table. All my text fields are Varchar. I was thinking maybe bit?
Many Thanks
I have a PHP page with text and Database fields.
This is the code that draws the checkbox:
<tr>
<td width="43"><label for="business_type">Salon</label></td>
<td width="30"><input type="checkbox" name="business_type[]" id="business_type" value="salon" /></td>
<td width="38"><label for="business_type">Mobile</label></td>
<td width="30"><input type="checkbox" name="business_type[]" id="business_type" value="mobile" /></td>
<td width="53"><label for="business_type">Student</label></td>
<td width="25"><input type="checkbox" name="business_type[]" id="business_type" value="student" /></td>
<td width="37"><label for="business_type">Other</label></td>
<td width="434"><input type="checkbox" name="business_type[]" id="business_type" value="other" /></td>
</tr>
This is the code that stores the texts fields in the database:

mysql_query("INSERT INTO `data` VALUES ('$trainee_name', '$company_name', '$address', '$telephone', '$email_address', '$website', '$trainer_name', '$training_date', '$trainer_notes', '$area_consultant')");
Print "Your information has been successfully added to the database.";

You can concatenate with | or , the selected values and store them in text filed. So that you can split the entries back.
BTW, you do know that you should be more careful with handing input data to mySQL?

Are you able to show me an example? I'm new to this.
Enterint the above code did nothing to the database. Isn't that because a VARCHAR field is purely for storing text? Please feel free to tell me i'm talking rubbish lol.
