如何使单选按钮返回布尔值true / false而不是on / off
I want that my radio buttons return me a Boolean value true or false instade of on/off
So I pass the true/false in the value of the input :
<label>Male
<input type="radio" name="IsMale" value="true" />
</label>
<label>Female
<input type="radio" name="IsMale" value="false" />
</label>
but it returns me a true/false in a text format. Please masters how could I get them in a booleen format ?
More details : In fact I need to store my $_POST array in a file.txt, and for my radio button I need to store for example :
array ( "IsMale" => true );
and not :
array ( "IsMale" => "true" );
You'll have to check the data and modify it.
if(isset($_POST['SubmitButton'])) {
$_POST['IsMale'] = $_POST['IsMale'] == 'true' ? true : false;
}
You cannot make radio buttons or any other form element directly submit a PHP true value, only a string such as "true".
To solve your problem, you would have to change the value of the $_POST item in your PHP file.
//Form has been submitted
if(isset($_POST['submit'])) {
//Radio button has been set to "true"
if(isset($_POST['IsMale']) && $_POST['IsMale'] == 'true') $_POST['IsMale'] = TRUE;
//Radio button has been set to "false" or a value was not selected
else $_POST['IsMale'] = FALSE;
}
Edit: Ben has provided a functional solution using ternary operators which is a shorter alternative. The example above may clarify exactly what is going on in the process (in a more verbose form).
