Hello all,

I am working on some programming to check is a variable
is a NO or YES then covert the variable to a 0 or 1

Example:

$bozo1 = "no";

$bozo2 = "yes";

Yes $bozo1 = a no how do i change it to a 0
Then if $bozo2 = a yes how to change the variable to a 1.

THank you advance 🙂

if ($bozo1 == 'no') {$bozo1 = 0;}
if ($bozo2 == 'yes') {$bozo2 = 1;}

or you could write a more generalized function:

function check_bool ($arg)
{
$arg = strtolower ($arg);
if ($arg == 'yes') {$arg = 1;}
if ($arg == 'no') {$arg = 0;}
return $arg;
}

barand

$bozo = $bozo == 'YES' ? 1 : 0;

Thank you.

Only one thing i am not sure of the function you made.

I have about 65 $yes1_1 $yes1_2a check to check if there yes or no. How could i use the function you made to do this?

Thank you for all your help 😃

devinemke

are you checking if the NAME of the varibale contains a "yes" or a "no" and are you checking the VALUE of the varibale for "yes" or "no"?

Hello all,

Do you mean something like this:

The data field is a text field and customer is entering a yes or no in the data field.

I have to convert the variable $yes1_1 form either a no or a yes to a 0 or 1.

Thank you again.

If your list is variable in size, you can use an array to do it:

$otheranswers = array(
0=>"true",
1=>"false",
"stanley"=>"NULL",
3 => "burnt_toast");
$var1 = 0;
$var2 = "stanley";
print $otheranswers[$var1];
print $otheranswers[$var2];
?>

That lets you put the logic for replacement in a single array, not in dozens of lines of code all over the page.

if you have a form and you want users to enter boolean data (yes/no, true/false, 1/0) then you should use a radio button rather than a text field:

<form action="<?= $_SERVER['PHP_SELF'] ?>" method="POST">
Is PHP your favorite language?<br>
<input type="radio" name="fav_lang" value="1"> yes<br>
<input type="radio" name="fav_lang" value="0"> no
<br>
<br>
<input type="submit" name="submit" value="submit">
</form>

<?
if (isset ($_POST['submit']))
{
	if (isset ($_POST['fav_lang']))
	{
		if ($_POST['fav_lang'] == '1') {echo 'PHP IS your favorite language!';}
		if ($_POST['fav_lang'] == '0') {echo 'PHP IS NOT your favorite language!';}
	}
	else
	{
		echo 'Please answer the question!';
	}
}
?>

did you mean custmer is gonna enter 65 fields as YES or NO?

if that is the case you might have to use a radio button not
text field.

once you use radio buttun give the value
like

<input type="radio" name="opt" value = "1"> yes
<input type="radio" name="opt" value = "0"> no

So if they click on yes you will get 1, if NO you get 0

you don't have to use any fuction to check it.

hey devinemke !! we both have the same wave length

See the timestamps !! you send your post just before 2 mins i did. I did't see your. you almost gave the same solution i gave.

Here i have an idea.

since there are 65 entries for it. you better name your radio buttons in a better way.

<form action="<?= $_SERVER['PHP_SELF'] ?>" method="POST">
Is PHP your favorite language?<br>
<input type="radio" name="fav_lang[1]" value="1"> yes<br>
<input type="radio" name="fav_lang[1]" value="0"> no
<br>
<input type="radio" name="fav_lang[2]" value="1"> yes<br>
<input type="radio" name="fav_lang[2]" value="0"> no
<br>

....
....
<input type="radio" name="fav_lang[65]" value="1"> yes<br>
<input type="radio" name="fav_lang[65]" value="0"> no
<br>

<?
if (isset ($POST['submit']))
{
foreach( $POST['fav_lang] as $fav_lang)

{
if ($fav_lang == '1') {echo 'PHP IS your favorite language!';}
if ($fav_lang == '0') {echo 'PHP IS NOT your favorite language!';}
}
}
?>
