Won't work in IE

[ryeman98]

I know, I know, we all hate IE but I made a Rock, Paper, Scissors game and it works fine and dandy in FF but breaks down in IE. The problem, the users guess won't submit. Any suggestions?

Yep, I suggest you either post a link or some code or preferably both, since we aren't magicians and can't tell you anything without seeing what you've done.

Sorry about that, I kinda ran off too quick.

 

<?php
if ($_GET['act'] == "choose") {
echo "<form action='rps.php?act=result' method='post'>";
echo "<table align='center' width='10%' border='0'><tr><td align='left'>";
echo "<input type='image' name='choice' value='rock' src='../images/rock.gif'>";
echo "<input type='image' name='choice' value='paper' src='../images/paper.gif'>";
echo "<input type='image' name='choice' value='scissors' src='../images/scissors.gif'>";
echo "</td></tr></table>";
echo "</form>";

} elseif ($_GET['act'] == "result") {
$_SESSION['pageview'] = $_SESSION['pageview']+1;

if ($_SESSION['pageview'] > 1) {
	echo "<a href='/rules.php'>No cheating!</a>";
} else {
	$user_choice = $_POST['choice'];
	$comp = array("rock",
				"paper",
				"scissors");
	$rand_comp = rand(0, 2);
	$comp_choice = $comp[$rand_comp];

	echo "You chose: ". $user_choice ."<br />";
	echo "Comp chose: ". $comp_choice ."<br /><br />";
?>

 

As you can see, in IE ONLY, $user_choice is NULL. In Any other browser, it has what the user submitted.

Bumping because it's still not fixed.

Your form doesn't have a "submit" botton?

[ryeman98]

The images are the submit buttons.

This is all IE's fault. Ha Ha.  This is a case where IE gets it right and other browsers do it wrong.

 

When an image submit is clicked, it properly acts like an image map and returns the x and y co-ordinates of the clicked point relative to the upper-left corner of the image.  If the image name is banana, then a POSTed form will provide the co-ordinates as $_POST['banana_x'] and $_POST['banana_y'].  $_POST['banana'] will not exist.

 

With multiple image submits each will, of course, need a different name not the same name and a different value.

Try this:

<?php
if ($_GET['act'] == "choose") {
echo "<form action='rps.php?act=result' method='post'>";
echo "<table align='center' width='10%' border='0'><tr><td align='left'>";
echo "<input type='image' name='choice' value='rock' src='../images/rock.gif'>";
echo "<input type='image' name='choice' value='paper' src='../images/paper.gif'>";
echo "<input type='image' name='choice' value='scissors' src='../images/scissors.gif'>";
echo "</td></tr></table>";
echo "</form>";

} elseif ($_GET['act'] == "result") {
$_SESSION['pageview'] = $_SESSION['pageview']+1;
}	
if ($_SESSION['pageview'] > 1) {
	echo "<a href='/rules.php'>No cheating!</a>";
} else {
	$user_choice = $_POST['choice'];
	$comp = array("rock",
				"paper",
				"scissors");
	$rand_comp = rand(0, 2);
	$comp_choice = $comp[$rand_comp];

	echo "You chose: ". $user_choice ."<br />";
	echo "Comp chose: ". $comp_choice ."<br /><br />";
?>

monkeybidz, just posting random code without stating what you changed or fixed in it does not help the OP now, nor anyone that happens to find the thread in the future with the same problem.

 

AndyB's post address the actual problem with the code. Also see this in the php manual - http://www.php.net/manual/en/faq.html.php#faq.html.form-image
