html form wont submit POST
I’m workin on a Rock Paper Scissors game to practice my html and php, everythig was fine until I tried to submit a user-selected answer in a POST. I´ve been checking and nothig is submitted when the button Play is pressed.
This is my html code:
<html> <head> <title>Oscar Felipe Ramírez Pardo</title> <meta charset="UTF-8"> </head> <body> <h1>Rock Paper Scissors</h1> <p>Welcome: <?=htmlentities($_GET['name'])?></p> <forms method="POST"> <p> <select name="option"> <option value="Select" checked>Select</option> <option value="Rock">Rock</option> <option value="Paper">Paper</option> <option value="Scissors">Scissors</option> <option value="Check">Check</option> </select> <input type="submit" value="Play" name="dopost"> <input type="button" value="Logout" name="logout"></p> </forms> <pre> <?php foreach($rslt as $k => $v){ echo $v."\n"; } ?> </pre> </body> </html> And this is the model control before it:
<?php $rslt=array("Please select a strategy and press Play."); $names=array("Rock","Paper","Scissors"); if(!isset($_GET['name'])) die("Name parameter missing"); if(isset($_POST['logout'])){ header("Location: login.php"); return; } function play($h){ $c=$names[rand(0,2)]; if($h===$c) $r="Tie"; else if($h==="Rock" && $c==="Scissors") $r="You win."; else if($h==="Scissors" && $c==="Paper") $r="You win."; else if($h==="Paper" && $c==="Rock") $r="You win."; else $r="You lose."; return "Your Play=$h Computer Play=$c Result=$r"; } if(isset($_POST['option'])){ if($_POST['option']==="Select") $rslt=array("You must select a strategy in order to play."); else if($_POST['option']==="Check"){ } else{ $rslt=array(play($_POST['option'])); } } ?> I don´t get anything when pressing either button as it shows here., but the source code shows the first php variables are being recognized.
I think that you have misspelled the tag <form> with <forms> amd you have to add an actions to specify the php page you want to call.
Like this:
<form method="POST" action="test.php"> <p> <select name="option"> <option value="Select" checked>Select</option> <option value="Rock">Rock</option> <option value="Paper">Paper</option> <option value="Scissors">Scissors</option> <option value="Check">Check</option> </select> <input type="submit" value="Play" name="dopost"> <input type="button" value="Logout" name="logout"></p> </form>
It’s not only forms thats wrong, you shouls also have an undefined error when you play. Add global $names in your play function. and add the result in a p or other tag instead of textarea is better to read
$rs = 1; $rslt = "Please select a strategy and press Play."; $names = array("Rock", "Paper", "Scissors"); if (!isset($_GET['name'])) die("Name parameter missing"); if (isset($_POST['logout'])) { header("Location: login.php"); return; } function play($h) { global $names; $c = $names[rand(0, 2)]; if ($h === $c) $r = "Tie"; else if ($h === "Rock" && $c === "Scissors") $r = "You win."; else if ($h === "Scissors" && $c === "Paper") $r = "You win."; else if ($h === "Paper" && $c === "Rock") $r = "You win."; else $r = "You lose."; return "Your Play=$h Computer Play=$c Result=$r"; } if (isset($_POST['option'])) { if ($_POST['option'] === "Select") $rslt = "You must select a strategy in order to play."; else if ($_POST['option'] === "Check") { } else { $rslt = play($_POST['option']); } } ?> <html> <head> <title>Oscar Felipe Ramírez Pardo</title> <meta charset="UTF-8"> </head> <body> <h1>Rock Paper Scissors</h1> <p>Welcome: <?= htmlentities($_GET['name']) ?></p> <form method="POST"> <select name="option"> <option value="Select" >Select</option> <option value="Rock">Rock</option> <option value="Paper">Paper</option> <option value="Scissors">Scissors</option> <option value="Check">Check</option> </select> <input type="submit" value="Play" name="dopost"> <input type="button" value="Logout" name="logout"> <p style="font-family:monospace"> <p> <?= $rslt ?> </p> </p> </form> </body> </html> 
I actually found too that the Logout button won’t work since it’s type is button and not submit therfore the post wasn’t submitted and the isset($_POST['logout']) never worked.
