View Full Version : First PHP form - Need guidance

Hey guys
New to PHP and programming in general. I am writing my first PHP form to spit out some "instant" answers based on user input. Basically, i want the form choices to change automatically(without page reload) depending on the choices made before it . I do not know AJAX or JS but if anyone is willing to help i would greatly appreciate it! Thanks in advance.

Not enough information ... we have no idea what your form is about, or what it's supposed to do.

I would say you can start here and find one closest to what you want.

Hey mlseim,
You actually helped me with my first problem so you have seen my form lol sorrry for not posting the first time though, it is below.

Basically, i will have 2 forms and one will show if $outside isset and the other will show if $inside isset but i do not want the user to have to reload the page. Does this makes sense? Thanks a million for your help.

<?php if($_POST['in_or_out'] == "inside" ) { $inside = $_POST['in_or_out']; } elseif($_POST['in_or_out'] == "outside" ) {$outside = $_POST['in_or_out']; }?>

<?php if(!isset($_POST["form"])) { ?>
<form action="<?php echo htmlentities($_SERVER['PHP_SELF']) ?>" method="post" name="form">
<p>Indoor or Outdoor : <select name='in_or_out'><option value=''>Select one</option><option name="inside" <?php if(isset($inside)){echo "selected"; }?> value="inside">Inside</option><option name="outside" <?php if(isset($outside)) {echo "selected" ; } ?> value="outside">Outside</option>
<?php if(isset($outside)) { ?>
<select name="application" >
<option value="opt1">opt1</option>
<option value="opt2">opt2</option>
<option value="opt3">opt3</option>
<?php } elseif(isset($inside)) { ?>
<select name="application" >
<option value="opt1">opt1</option>
<option value="opt2">opt2</option>
<?php } ?>

<br />
<input type="submit" name="submit" value="Submit">

<?php } ?>
