login error with Internet Explorer but not Firefox

[jakatu]

I am pretty new to web programming and I am experiencing a weird problem. I (or any user) can login to the site fine when using firefox or safari, but when I try using Internet Explorer, it doesn't work. It gives me an error message when I type in a bad access code but when it is right the page just refreshes and nothing happens.

I am inserting the code for the part that is goofy.

if(isset($_POST['submit'])) { //Form has been submitted

		$errors = array();


		//perform validations on the form data

		$required_fields = array('access');

		$errors = array_merge($errors, check_required_fields($required_fields, $_POST));


		$fields_with_lengths = array('access' => 30);

		$errors = array_merge($errors, check_max_field_lengths($required_fields, $_POST));


		$access = $_POST['access'];


		if ( empty($errors)) {

			// Check database to see if the company and hashed password exist there.

			$query = "SELECT  users_id, id 

			FROM subjects 

			WHERE access = '{$access}' ";

			$result_set = mysql_query($query);

			confirm_query($result_set);

			if (mysql_num_rows($result_set) == 1) {

				//company/password authenticated

				// and only one match

				$found_client = mysql_fetch_array($result_set);


				redirect_to("public.php?user=" . $found_client['users_id'] . "&subj=" . $found_client['id']);

			} else {

				// company/password combo was not found in the database

				$message = "Company and password combination incorrect.<br>

					Please make sure your caps lock is off and try again.";

			}

		} else {	

			if (count($errors) == 1) {

				$message = "There was 1 error in the form.";

			} else {

				$message = "There were ". count($errors) . " errors in the form.";

			}

		}

	} else {//Form has not been submitted.

		$company = "";

		$access = "";

	}

[/Code]

 

I know that the functions that i created work i just cant figure it out. I am pretty sure its not the sql portion either. I have taken that out and just put the access code in the script just to check. It still didn't work.

 

If anybody has ever experienced this let me know I am not alone and moreover those who have overcome this issue please share your knowledge with me.

 

Thank you for your help

I have also taken out the redirect_to part and just listed a positive message to be displayed if the access code is correct.

That wont show up either. If I type in a bad access code it will however display the negative message

Well...PHP won't produce different results between browsers because it is a server side language. Either something is funky in your form when submitting the data, or the redirect_to() function is doing something funky.

 

After this line:

if(isset($_POST['submit'])) { //Form has been submitted

put this:

print_r($_POST);exit;

 

And make sure the data being submitted looks identical in FF and IE.

 

Also, what is the code for redirect_to()?

[ignace]

where do you print the $message to the screen, or do you print it at all?

 

and same question as rhodesa, whats the code for redirect_to()?

[jakatu]

this is in the body section of my page

<table id="structure">
	<tr>
		<td valign="top" id="navigation">
			<h2>Login</h2> 
			<br>
			<form action="user_login.php" method="post">
				<?php if (!empty($message)) { echo "<p class=\"message\">" . $message . "</p>";} ?>

and the redirect_to function is as follows

function redirect_to( $location = NULL ) {
	if ($location != NULL) {
		header("Location: {$location}");
		exit;
	}

}

[jakatu]

have put in the print_r thing and result in firefox is a blank page with this message;

"Array ( [access] => password [submit] => Login )."

 

Explorer still just does the refresh thing.

 

[rhodesa]

What does your submit button look like? If IE is not showing that data on a blank page, then this line is returning false:

if(isset($_POST['submit'])) { //Form has been submitted

 

you  may want to try and use this instead:

if($_SERVER['REQUEST_METHOD'] == 'POST') { //Form has been submitted

[ignace]

i would use a strcmp() to check wether a HTTP POST header was sent

 

<?php

if (strcmp(strtolower($_SERVER['REQUEST_METHOD']), 'post') === 0) { // form has been submitted

?>

[jakatu]

oooooHHHHHHH RHODESA I COULD KISS YOU!!!!!!!!!!!!!!!!!!!!

you made me a very happy man. and saved my bacon

thank you soo much

the "if($_SERVER['REQUEST_METHOD'] == 'POST') "

did the trick.

 

thank thank thank you

If you post your FORM, we could probably show you how to fix it.

I'll take a wild guess that the submit button is an image (there seems to be a lot of that going on lately.)
