Small question

[langer]

How do you retreive the input from an option box? Like for the example, lets say you have three options: Cat, Dog, Bird and the select is called animals. What code do you use to get the user input?

ie.

<?php

if ($_POST['animals'] == "Cat") {
print "cat";
}
?>

I'm really new to PHP and I'm trying to figure this out. Any help would be appreciated, thanks.

All you need is a standard html form

<form name="formnamehere" method="post" action="#">
<select name="animals" id="animals">
<option value="Cat" selected>Cat</option>
<option value="Dog">Dog</option>
<option value="Bird">Bird</option>
</select>
<input type="submit" name="Submit" value="Submit">
</form>

Sorry, my post was brief I had to do it quickly.

The HTML isn't the problem, I have that done - easily. I need to know the PHP code to get the user option.

I'm not sure I understand you.
If you post the variable "animals" with selected value "cat"
It is much the same as the statement
$animals="cat";
so you could echo out the selection

eg echo $animals;

Am I understanding you?

If using the POST method in your form, use $POST['animals'] and if using the GET method, use $GET['animals']

It is case sensitive, so $POST['animals'] does not mean the same thing as $POST['AniMalS']

fizzwizz, if you post the variables (and Cat is the one posted) and register globals is off, then this is not a true statement:

$animals = "Cat"

This is true however...

$_POST['animals'] = "Cat"

and you would echo it out as:

echo $_POST['animals'];

UNLESS you declare the variable...

$animals = $_POST['animals'];
echo $animals;

I just need you to verify this code:

<?php
if ($_POST['animals'] == "Cat") {
print "cat";
}
?>

I'm just trying to figure out how to print the input from the option box. The select name is called: animals . It doesn't seem to work for me...

Ah - there it is.

Thank you both very much for your help. I appreciate it.

Surely 'Cat' is the value not the variable?

and you would echo it out as:

echo $_POST['animals'];

UNLESS you declare the variable...

$animals = $_POST['animals'];
echo $animals;

I always echo posted variables without declaring them ... works for me!!

...which means you have register_globals ON which is ill advised.

Then I'd better adopt the $_post[] technique asap

Thanks ... Fizz
