PHP form is not posting data

I have a form on an HTML/PHP page.

I have the same exact code on other pages on the site, and it works fine. I cannot figure it out.

Form:

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

    <input name="prize_id" type="hidden" value="<?php echo $prize_id; ?>" />

    <input name="ContestEntry" type="submit" class="submit" value="Enter me in the Raffle!" />

</form>

I looked at the HTML source code, and the action populates the correct page, and $prize_id populates the correct info in the value.

PHP:

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

    //...code to enter data into form, irrelevent since it won't post anything anyway.

}

else {

    echo 'Nothing posted from form';

}

"Nothing posted from form" always shows, and no data is being entered into the database. I've tried changing the form name to 5 different things, thinking maybe there was a conflicting name somewhere, but nothing works.

Any ideas?

If all you need to achieve is check whether the form is submitted or not, it's better to check that the request type is a POST:

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Process form
} else {
    // Nothing posted!

}

Also change your submit button to:

<button type="submit">Submit</button>

and see what happens

Consider adding what you're looking for as another hidden field:

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

    <input name="prize_id" type="hidden" value="<?php echo $prize_id; ?>" />
    <input name="ContestEntry" type="hidden" value="Enter me in the Raffle!" />

    <input type="submit" class="submit" />

</form>

The code you posted actually works for me.

But, if you still can't get it working, I would try checking to see if prize_id is set rather than the button. The PHP script is executed when the form is submitted.

Also, I would recommend that you don't use $_SERVER['PHP_SELF'] as the form action. According to https://stackoverflow.com/a/14093363/3593228, that can make it easy for attackers to insert malicious data. Instead, leave the action empty.

The if Condition is not working because you put it on Button, instead of this just make an hidden field in the form to check form is submit or not like as you already have one. Or make new for this form.

<input name="prize_id" type="hidden" value="<?php echo $prize_id; ?>" />
