hello guys, ive made a script to basically execute two different things depending on which radio button is selected:

print"<div style=\"position:absolute;bottom:20px;right:20px;\">";
print"<form method=\"post\" action=\"\">";
print"<input type=\"radio\" name=\"lang\" value=\"English\" >English<br>";
print"<input type=\"radio\" name=\"lang\" value=\"German\">German";
print"<input type=\"submit\" value=\"Change\" />";
print"</form>";
print"</div>";

$myRadio = intval($_POST['lang']);
if ($myRadio == "English") {          

	print"<h1>English</h1>";
	


}elseif ($myRadio == "German") {

	print"<h1>German</h1>";
	
}

this doesnt work, firstly for some reason it just displays English straight away even though nothing is even ticked yet. and when i do change to "german" and click the button, it doesnt change...

 

 

PLEASE help me guys, how would i make it work.

Remove intval(). This converts a value into integer. The if/elseif is comparing strings not integers.

The comparison should only be performed if $_POST['lang'] exists.

if(isset($_POST['lang']))
{
	$myRadio = $_POST['lang'];

	if ($myRadio == "English")
	{          
		print"<h1>English</h1>";
	}
	elseif ($myRadio == "German")
	{
		print"<h1>German</h1>";
	}
}

It Displays the correct language based on the selection I make, and nothing if I didn't chose a language.

print"<div style=\"position:absolute;bottom:20px;right:20px;\">";
print"<form method=\"post\" action=\"\">";
print"<input type=\"radio\" name=\"lang\" value=\"English\">English<br>";
print"<input type=\"radio\" name=\"lang\" value=\"German\">German";
print"<input type=\"submit\" value=\"Change\" />";
print"</form>";
print"</div>";


if(isset($_POST['lang']))
{
	$myRadio = $_POST['lang'];

	if ($myRadio == "English")
	{          
		print"<h1>English</h1>";
	}
	elseif ($myRadio == "German")
	{
		print"<h1>German</h1>";
	}
}

That is without selecting ANyTHING or clicking anything, it simply does that when i load the page. and thats all the code for this. 

i will now paste the code for that entire page:

<?php

$safe_myuri = addslashes($myuri);

$row_parent_folder_title = $row_object_title;
$row_parent_url = $row_url;

$myquery = sql_query("SELECT * FROM webmanage_objects AS a WHERE a.parentid='$row_objectid' AND a.is_visible='1' AND a.archived='0' AND a.url='$safe_myuri' LIMIT 0,1");

if (!sql_num_rows($myquery)) {
	require("source/404error.php");
	exit();
} else {
	$myrow = sql_fetch_assoc($myquery);
	transfer_row($myrow);
}

//
// Machines for sale view
//

print_header($row_object_title);

print "<div class=\"heading\"><div class=\"b\"><h2><a href=\"/machines-for-sale/\" style=\"text-decoration: none; color: #1e2a5f;\">Machines for Sale</a> > <a href=\"/machines-for-sale/$row_parent_url/\" style=\"text-decoration: none; color: #1e2a5f;\">$row_parent_folder_title</a></h2></div></div>\n";
print "<div class=\"clear\"></div>\n";

start_parkes_rounded();

print "<div class=\"hotspot blue tlc machine\">\n";
print "<div class=\"item\">\n";
print "<h2>$row_object_title</h2>\n";
print "<p class=\"red fRight cRight\"><strong>Stock Ref: $row_object_tagline</strong></p>\n";
print "<div class=\"clear\"></div>\n";

print "<div class=\"images\">

//]]>
</script>\n";

//
// Images Container
//

$images = array();

$myquery = sql_query("SELECT * FROM webmanage_uploads WHERE filestore='image' AND objectid='$row_objectid' ORDER BY ordering, fileid");
while ($myrow = sql_fetch_assoc($myquery)) {

	$row_fileid = $myrow["fileid"];
	if (is_file("$imagebase_location/$row_fileid"."_machine_large.jpg")) {
		$images[] = "/images/managed/$row_fileid"."_machine_large.jpg";
	}

}

print "<div id=\"ctl00_Content_ImagesUP\">\n";

print "<ul>\n";

$counter = 0;

foreach($images as $myimage) {

	$counter++;
	if ($counter < 10) { $counter_text = "0$counter"; } else { $counter_text = "".$counter; }
	$myimage_small = str_replace("machine_large","machine_small",$myimage);

	if (($counter % 3) == 0) {
		$padding_right = "padding-right: 0px;";
	} else {
		$padding_right = "padding-right: 15px;";
	}

	print "<li id=\"ctl00_Content_RepMachineImages_ctl{$counter_text}_ImageItem\" style=\"$padding_right\"><a class=\"imagesListImage\" href='$myimage' target=\"_blank\" style=\"margin: 0px; float: left;\"><img id=\"ctl00_Content_RepMachineImages_ctl{$counter_text}_ListImage\" src=\"$myimage\" height=75 style=\"border-width: 0px; margin-left: auto; margin-right: auto;\" /></a></li>\n";
