[RESOLVED] Little help with an input field; understanding.

[crazygrunt]

Now I can't seem to figure this out, I just want to understand how it works.

        <p><input type="submit" name="submit" value="Submit" /></p>
        <input type="hidden" name="submitted" value="TRUE" />

using this with it:

if(isset($_POST['submitted'])) {

// do something

} else {
//do something else
}

What I don't understand is how the input type hidden works with the submit button. What I mean by that is how when I press submit it connects to the hidden value to set it so that the if statement runs the first part. Thanks.

I think I may understand it now. correct me if I am wrong but when this is between the form tags it will only be set when the form is submitted:

<input type="hidden" name="submitted" value="TRUE" />

So any hidden input type is submitted and usable by the php code after the form submit value is set:

<input type="submit" name="submit" value="Submit" />

Is that correct?

yes, all input inside the form tags
will be sent with values,
when button SUBMIT is clicked

Following script will dump out all values, the array $_POST
in this case 3 variable values are posted, sent
using method="post"

<form method="post">
Some text: <input type="text" name="sometext" value="" /><br />
<input type="hidden" name="submitted" value="TRUE" />
<input type="submit" name="submit" value="Submit" />
</form>
<?php

if(isset($_POST['submit'])){ //if submit button value exists
    // show all posted values
    echo '<pre>'.print_r($_POST, true).'</pre>';
}

?>
