[SOLVED] PHP & checkboxes

[Miko]

Hello,

 

I'm making a form with a search input + 3 different checkboxes.

So making the form is absolutely no problem, the search input either.

 

The thing that I want is that a user can select one of the 3 checkboxes and in function of that (+ search input) they will search in the database.

 

Anyone an idea how to pull this together?

 

Thanks,!

If you want the user to be allowed to only select one item out of a possible three your best bet would be to use radio buttons instead.

Thought allso that would work but it strangely enough, it doesn't.

I can still click all three at the same time  ???

You're probably giving them all different names then - very common mistake and easy to make.

 

<input type="radio" name="myradio" value="1"> Cheese
<input type="radio" name="myradio" value="2"> Onion
<input type="radio" name="myradio" value="3"> Cheese & Onion

 

When you get the value of the radio button depending on which one is selected will return the correct value. Grouped radio buttons must all be named the same.

Hi,

 

Your right, now it works

But will this work for my php script?

 

I use

$_POST

and variables to define it.

Let's make a form:

<form action="<?php echo $_SERVER['PHP_SELF']; method="post">
Name: <input type="text" name="username"><br>
Favourite Food:
<input type="radio" name="myradio" value="1"> Cheese<br>
<input type="radio" name="myradio" value="2"> Onion<br>
<input type="radio" name="myradio" value="3"> Cheese & Onion<br><br>
<input type="submit" name="subsend" value="Answer Questions">

 

Depending on the ACTION part of the FORM declaration (POST or GET) depends on how you pick up the data.

 

POST sends data in packets where as GET appends the data onto the URL. We've used POST so we'll read it using this:

$uname=$_POST['username'];
$food=$_POST['myradio'];
if (isset($_POST['subsend'])) {
  echo 'User '.$uname.' selected option '.$food;
}
