PHP wont recognise POST from HTML page

npowell

Hi,

I've been having a ball over the last few days trying to configure IIS, PHP5 and MySQL...

Finally got it all working then tried a simple form script and discovered that PHP wouldn't print the variables from the form to the screen!

<?PHP
print("Hello, $name! You are $age years old!");
?>

The above scripts are all I used. The HTML form works fine and loads the php page but the contents of the $name and $age variables are blank.

Can anyone help me on this, I'm very new and don't know much about the php.ini file to get this working.

Cheers,

Nick :bemused:

Hi nick

Whenever you post the form , the values that u have submitted are stored the the super global variable called as $POST. So to access these values in PHP, you have to take it from the $POST.

Say ...u want to access the vaues Name, Age...
Then simply write
print_r($POST['name']) and print_r($POST['age']).
The parameter you specify in $_POST is the name of the text field you have given in the html form..

to print the whole array to type print_r($_POST);

thats it..
hope this clears your doubt.

Thanks for your reply,

that does clear some things up a little although this tutorial i was reading from said it could be done this way...
check it out -->

I tried your example and it didn't work as expected...

The output i received was --> nick45Hello, 1! You are 1 years old!

Using this code...

<?PHP

$name = print_r($POST['name']);
$age = print_r($POST['age']);
print("Hello, $name! You are $age years old!");

Am i missing something in the php.ini file?

Any ideas? 😕

Just worked it out...

the $_POST[] does not like the variables surround in single or double quotes...

This worked --> <?PHP

print("Hello, $POST[name]! You are $POST[age] years old!");

Although it doesn't solve the tutorial that didn't use the $_POST method, not to mention I remenbered seeing used on a video tutorial at http://www.vtc.com

Hi again,

thanks buddy...i was not aware of the php.ini settings

I set the "regester_global = on" in php.ini setting ...and restarted the apache server and then as u said accessed the variables as $name and $age and it worked.....

Thanks for that information..
Looking forward for ur reply..

as you have posted in ur reply...this is a wrong code

<?PHP

$name = print_r($POST['name']);
$age = print_r($POST['age']);
print("Hello, $name! You are $age years old!");

you cannot assign $name=print_r($POST['name']);
because print_r function returns a boolean..so the value in $name will be a boolean...
u can give $name = $POST['name'];
