Working with forms in PHP - Conclusion

(Page 7 of 7 )

That's it. Nothing really to forms and PHP. PHP just makes it so simple it is unbelievable. Below are the final versions of form.html and form.php. If you have any questions about this subject, ask it in our forum. Thanks for stopping by!

&lt;HTML&gt;
&lt;HEAD&gt;
&lt;TITLE&gt;A simple form&lt;/TITLE&gt;
&lt;/HEAD&gt;
&lt;BODY&gt;
&lt;FORM method="POST" action="form.php"&gt;
Fill in the text box: &lt;INPUT type="text" name="mytextbox" size="20"&gt;&lt;BR&gt;
Check me or not: &lt;INPUT type="checkbox" name="mycheckbox[]" value="1"&gt;&lt;BR&gt;
Check me or not: &lt;INPUT type="checkbox" name="mycheckbox[]" value="2"&gt;&lt;BR&gt;
Check me or not: &lt;INPUT type="checkbox" name="mycheckbox[]" value="3"&gt;&lt;BR&gt;
Choose one:
Blue &lt;INPUT type="radio" name="myradio" value="blue" CHECKED&gt;
Green &lt;INPUT type="radio" name="myradio" value="green"&gt;
Yellow &lt;INPUT type="radio" name="myradio" value="yellow"&gt;&lt;BR&gt;
Select something from this list:
&lt;SELECT name="myselectbox"&gt;
&lt;OPTION value="dog"&gt;Dog&lt;/OPTION&gt;
&lt;OPTION value="cat"&gt;Cat&lt;/OPTION&gt;
&lt;OPTION value="pig"&gt;Pig&lt;/OPTION&gt;
&lt;/SELECT&gt;&lt;BR&gt;
&lt;TEXTAREA name="mytextarea" rows="4" cols="30"&gt;&lt;/TEXTAREA&gt;&lt;BR&gt;
&lt;INPUT type="submit" name="mybutton" value="Click me!"&gt;
&lt;/FORM&gt;
&lt;/BODY&gt;
&lt;/HTML&gt;

&lt;HTML&gt;
&lt;HEAD&gt;
&lt;TITLE&gt;Doing something with the form&lt;/TITLE&gt;
&lt;/HEAD&gt;
&lt;BODY&gt;
&lt;?
if(isset($_POST['mybutton'])) {
    echo "Great! You clicked the button!\n";
    echo "&lt;BR&gt;You typed &lt;b&gt;" . $_POST['mytextbox'] . "&lt;/b&gt; in the textbox.\n";
    if(isset($_POST['mycheckbox'])) {
        echo "&lt;BR&gt;You checked the checkbox.\n";
    } else {
        echo "&lt;BR&gt;You didn't check the checkbox.\n";
    }
    foreach($_POST['mycheckbox'] as $value) {
        echo "&lt;BR&gt;You clicked checkbox number " . $value . "\n";
    }
    echo "&lt;BR&gt;The color you picked was " . $_POST['myradio'] . "\n";
    echo "&lt;BR&gt;" . $_POST['myselectbox'] . " was chosen from the select list.\n";
    echo "&lt;BR&gt;In the textarea, you typed: " . $_POST['mytextarea'] . "\n";
} else {
    echo "Hmm...you must have come to this script without clicking the button.\n";
}
?&gt;
&lt;/BODY&gt;
&lt;/HTML&gt;
