Can't get Radio Checked to Post

[unemployment]

I'm creating a multi step form but $_POST['acc_type']; is not working properly.  Sometimes it will post correctly and other times it goes to the error message even after I preform the exact same steps.  It is not being posted the same everytime.  Is there a better way to do this?

 

        <?php

        $step = 1;

if(isset($_POST['continue_1']) && isset($_POST['acc_type']))
{
	echo $_POST['acc_type'];

	if(($_POST['acc_type'] != '') && (($_POST['acc_type'] == 0) || ($_POST['acc_type'] == 1)))
	{
		$step = 2;
	}
	else
	{
		echo '<p class="errormessage error">To create an account you must select a goal.</p>';
	}
}

if($step == 1)
{

?>
<form action="join.php?key=<?php echo $_GET["key"]; ?>" method="post" id="form" name="signup">
	<fieldset class="fieldset2">
		<legend>Primary Goal</legend>
		<h2 class="mts">What goal do you want to achieve?</h2>
		<div class="ptm pbs phm tcenter">
			<input id="entButton" class="radioAlign" type="radio" name="selector" value="1" />
			<label for="entButton" class="entrepreneur mrl">venture</label>
			<input id="invButton" class="radioAlign mll" type="radio" name="selector" value="0" />
			<label for="invButton" class="investor">flow</label>
		</div>
	</fieldset>
	<div class="signUp mbl pbl" id="continue">
		<input type="submit" id="continuebtn" name="continue_1" value="Continue" />
		<input type="hidden" name="acc_type" value="<?php echo (isset($_POST['selector'])) ? $_POST['selector'] : ''; ?>" />
	</div>
</form
        <?php

}
else if($step == 2)
{
                 echo "This is step 2";
         }

         ?>

Something has to be different. Have you tried to print_r() the $_POST array and compare the differences between when it works and when it doesn't?

No, I've never done it.  The $_POST variable is an array?  I suppose that makes sense.  Let me try it.

Wow... thank you.  I printed the array and was able to fix my problem.  I didn't even need to use the hidden input.  Apparently the input with the name selector was already being posted.  Thank you for increasing my knowledge of php

Yeah, it's an array. It's probably best to print_r() it inside of <pre> tags so gets formatted for easier readability.

 

echo '<pre>';
print_r($_POST);
echo '</pre>';
