Marcos01 Posted November 13, 2008 Share Posted November 13, 2008 Hello, I would like to know if it is possible to print/echo the name from a input type radio instead of the value. I am trying to do it with this simple form: $A='0101'; print($_POST['\"$A\"']); echo '<form id="form " name="form1" method="post" action="'.$_SERVER['PHP_SELF'].'">'; echo '<label>question '; echo '<input type="radio" name=\"$A\" id="q1" value="10" />TEST</label>'; echo '<input name="next" type="submit" /> </form>'; Link to comment https://forums.phpfreaks.com/topic/132547-echoprint-form-input-name-instead-of-the-value/ Share on other sites More sharing options...
JasonLewis Posted November 13, 2008 Share Posted November 13, 2008 You can loop through and echo out the names of the $_POST array. foreach($_POST as $key => $value){ echo $key . "<br />"; } You can also use array_keys to make a new array out of the keys of an existing array. $keys = array_keys($_POST); But why? You can't do this another way?

Marcos01 Posted November 13, 2008 Author Share Posted November 13, 2008 Hello ProjectFear, thanks for your help. With the foreach code I get more data then I need. It also gives me the name of the button. I have questionnumber and page in the name and the answer in the value. No clue if it can be done differently.

JasonLewis Posted November 14, 2008 Share Posted November 14, 2008 It could, if its a multiple choice quiz you could do something like this: <?php $answers = array("a","c"); //An array of your answers, in order. if(isset($_POST['submit'])){ if(count($_POST['question']) != count($answers)){ //They didn't answer all the questions! echo "Sorry you didn't answer all the questions."; }else{ //Create 2 arrays, one can store the correct answers and one can store the incorrect. Of course you can just use one array for this and make it store another array. $correct = array(); $wrong = array(); //Begin a loop through all the questions, $question is the question number and $answer contains either a, b or c (you could make this go up to anything). foreach($_POST['question'] as $question => $answer){ //If $answer is the same as the answer specified in our $answers array. if($answer == $answers[$question]){ //Add it to the correct array. $correct[] = $question; }else{ //They got it wrong, add it to the wrong array. $wrong[] = $question; } } //Show the results to the user. echo "Thankyou for doing the quiz. Here are your results:<br />"; echo "You got <strong>" . count($correct) . "</strong> questions right and <strong>" . count($wrong) . "</strong> questions wrong!<br /><br />"; } } echo <<<html <form action="" method="post"> Question 1: Answer is A.<br /> <input type="radio" name="question[0]" value="a" />A<br /> <input type="radio" name="question[0]" value="b" />B<br /> <input type="radio" name="question[0]" value="c" />C<br /> <br /> Question 2: Answer is C.<br /> <input type="radio" name="question[1]" value="a" />A<br /> <input type="radio" name="question[1]" value="b" />B<br /> <input type="radio" name="question[1]" value="c" />C<br /> <input type="submit" name="submit" value="Go!" /> </form> html; ?> Why are you putting the question number and page in the same string?

Marcos01 Posted November 14, 2008 Author Share Posted November 14, 2008 Why are you putting the question number and page in the same string? I have 11 pages with questions. Generated from a database.
