please help with radio buttons

[afallingpanda]

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.

What is the output of

printf('<pre>%s</pre>', print_r($_POST, true));

When selecting a  language and then submitting the form?

What is the output of

printf('<pre>%s</pre>', print_r($_POST, true));

When selecting a  language and then submitting the form?

sorry? where did you get this from??

 

printf('<pre>%s</pre>', print_r($_POST, true));

[Ch0cu3r]

It is code I gave you so I can see the what is in $_POST when the form is submitted.

That is what the output is ( at the top its outputted).

 

And by the way that is outputed as soon as the page loads, then when i choose and click submit it stays the same.

 

THANKS SO FAR

[Ch0cu3r]

And that is with selecting English or German before clicking the button? If so then for some reason when the form is submitted the post data is not being sent.

 

So is there more code to this?

[afallingpanda]

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);
}

//

print_header($row_object_title);
