Simple php script with html form not working.
 
Greetings,

I am really stuck on this problem, so I hope someone can give me a hand:

I just installed Red Hat 9 for the third time. I installed PHP 4.3.5, MYSQL 4.0.18, and APACHE 2.0.49 via the following tutorial. //madpenguin.org/article751.html

I can create a php file that queries my MySQL database and return the results no problem. I can also create a simple php file that contains <?php phpinfo(); ?> and it returns all of my PHP Version 4.3.5 info. If seeing the phpinfo() results is needed, please let me know.

My problem is as soon as I create a php file with the below code, I get nothing. When I fill out the fields and hit submit, the fields clear and nothing else happens?

<html>

<body>



<form method="post" action="<?php echo $PHP_SELF?>">

First name:<input type="Text" name="first"><br>

Last name:<input type="Text" name="last"><br>

Address:<input type="Text" name="address"><br>

Position:<input type="Text" name="position"><br>

<input type="Submit" name="submit" value="Enter information">

</form>



</body>

</html>


I have been looking all over in different forums for information on this problem. I am a newbie to Linux, so I am kind of doing a trial and error. The only changes I have made to MySQL, PHP, or APACHE files are the ones listed at //madpenguin.org/article751.html The only exception is I changed register_globals = ON.

Please let me know if i can provide any additional information to assist in the solution.

Thank you for any help you can provide, I am at a loss what is wrong??

Cheers,

Travis

First of all, thank you kev82 for taking the time to look over my issue.

I apologize, but the snippett of code I pasted for you to examime was not the correct one. It was going on 2am when I posted, I will try to take my time in the future.

Below is the code I needed examined:

<html>

<body>

<?php



if ($submit) {

// process form

while (list($name, $value) = each($HTTP_POST_VARS)) {

echo "$name = $value<br>\n";

}

} else{

// display form

?>

<form method="post" action="<?php echo $PHP_SELF?>">

First name:<input type="Text" name="first"><br>

Last name:<input type="Text" name="last"><br>

Address:<input type="Text" name="address"><br>

Position:<input type="Text" name="position"><br>

<input type="Submit" name="submit" value="Enter information">

</form>

<?php


} // end if


?>


</body>



</html>





The above does nothing but clear the form fields, and that is it? In addition, if i run the code below, a blank entry is made in the mydb database.





<html>

<body>



<?php



if ($submit) {

// process form

$db = mysql_connect("localhost", "root");

mysql_select_db("mydb",$db);

$sql = "INSERT INTO employees (first,last,address,position) VALUES ('$first','$last','$address','$position')";

$result = mysql_query($sql);

echo "Thank you! Information entered.\n";

} else{



// display form



?>



<form method="post" action="<?php echo $PHP_SELF?>">

First name:<input type="Text" name="first"><br>

Last name:<input type="Text" name="last"><br>

Address:<input type="Text" name="address"><br>

Position:<input type="Text" name="position"><br>

<input type="Submit" name="submit" value="Enter information">

</form>



<?php



} // end if



?>



</body>



</html>


Thank you again to anyone that can help.

my php's not too great but the problem is obviously that "if($submit)" isnt working, at a guess i would say when you click the button your browser sets the submit variable but sets it to something that evaluates to false, try instead if(isset($submit))

you should use $_POST["submit"] instead of $submit, if the method is "get" then use $_GET["submit"], it is the way to access data since PHP 4.1.0

see "//cn.php.net/manual/en/language.variables.external.php"
