Reading checkboxes using webmatrix/razor - sql

Question

I'm having trouble with checkboxes on my site.
Here's the code I have so far:
#{
Layout = "~/_SiteLayout.cshtml";
WebSecurity.RequireAuthenticatedUser();
var db = Database.Open("StayInFlorida");
var rPropertyId = Request.QueryString["PropertyID"];
var Propertyinfo = "SELECT * FROM PropertyInfo WHERE PropertyID=#0";
var qPropertyinfo = db.QuerySingle(Propertyinfo, rPropertyId);
if(IsPost){
var sql = "INSERT INTO PropertyInfo (FePool, FeJac, FeGames) VALUES (#0, #1, #2) WHERE PropertyID=#3";
db.Execute(sql, Request["check1"], Request["check2"], Request["check3"], rPropertyId);
}
}
<form method="post">
<div>
<input type="checkbox" name="check1" value="true" />
Value 1
<br/>
<input type="checkbox" name="check2" value="check2" />
Value 2
<br/>
<input type="checkbox" name="check3" value="check3" />
Value 3
<br/>
<div>
<input type="submit" name="buttonSubmit" value="Submit" />
</div>
</form>
What I need to be able to do is check 3 columns in my database, and see if they are set to true (the columns are set as "bit"). If they are, then I want the checkbox to be shown as checked. I also want to be able to toggle these checkboxes and post "true" or "false" using a form, to post into the database.

Answer 1

You have a WHERE clause in your INSERT statement which makes no sense. If you are inserting, you create a new row. I suspect you intend to UPDATE an existing row in which case your SQL should be:
"UPDATE PropertyInfo SET FePool = #0, FeJac= #1, FeGames = #2 WHERE PropertyID=#3"
If a checkbox is not checked, nothing will be included for that checkbox in the Request.Form collection. If it is checked, the value passed is "on" by default, or whatever you have specified in the "value" attribute. For check1, that will be "true". For check2, that will be "check2". You need to establish whether the checkbox was actually included in the Request.Form collection and then set the values you want to commit to the database accordingly. If you want to pass true or false depending on whether the checkbox was checked, you can do this:
var c1 = !Request["check1"].IsEmpty();
var c2 = !Request["check2"].IsEmpty();
var c3 = !Request["check3"].IsEmpty();
var sql = "UPDATE PropertyInfo SET FePool = #0, FeJac= #1, FeGames = #2 WHERE PropertyID=#3";
db.Execute(sql, c1,c2,c3,rPropertyInfo);
Now that you have a series of booleans, you can use those to determine whether the checkbox is checked or not by using Conditional Attributes:
<input type="checkbox" name="check1" checked="#c1" /> Value 1<br/>
<input type="checkbox" name="check2" checked="#c2" /> Value 2<br/>
<input type="checkbox" name="check3" checked="#c3" /> Value 3<br/>
If you want to preset the values of the checkboxes from a query, you do that prior to the IsPost block:
var rPropertyId = Request.QueryString["PropertyID"];
var Propertyinfo = "SELECT * FROM PropertyInfo WHERE PropertyID=#0";
var qPropertyinfo = db.QuerySingle(Propertyinfo, rPropertyId);
bool c1 = qPropertyinfo.FePool;
bool c2 = qPropertyinfo.FeJac;
bool c3 = qPropertyinfo.FeGames;
Obviously you don't need var in front of the c1 - c3 variables in the IsPost block now.
