How do I get the value of a checkbox POST data?

Here is my code.

<?php
if($input->post->changesettings) {
    // $report->of(false);
    echo "<h1>deactivated is: <u>".$input->post->deactivated."</u>!</h1>";    
    $user->first_name = $input->post->first_name;
    $user->deactivated = $input->post->deactivated;
}
?>

<form method="POST" action="">
<input type="text" style="width: 390px; height: 48px; font-size: 2em;" class="mediumtext required styleme" name="first_name" value="<?=$user['first_name'];?>">
<input type="checkbox" name="deactivated" value="<?=$user['deactivated'];?>">
<input type="submit" name="changesettings" value="Change settings" class="bigbutton" />
</form>

 

It gets the value of the "first_name" text box, but not the "deactivated" checkbox. What is going on? What am I doing wrong? When printing the deactivated in the h1 tag, it always shows 0 when checked and submitted.

It works fine in my setup. Do you have any JS modifying the form? Also, check if you've mistyped ($input->post->deactivated == $something) as single = somewhere, rather than double == or triple === ?

<?php namespace ProcessWire;

if ($input->post->changesettings) {
    $checked = $input->post->deactivated;
    // checked == 1
}

?>
<form method="POST" action="">
    <input type="text" name="first_name" value="<?= $user['first_name']; ?>">
    <input type="checkbox" name="deactivated" value="1">
    <input type="submit" name="changesettings" value="Change settings" class="bigbutton"/>
</form>

at least in terms of usage in the api, checkboxes always have the value of 1, so you don't need to manipulate the value, just the checked status of the input.

I have found a fix for this. In HTML, whenever a checkbox is checked and is POSTed it has a value of "on". If the checkbox is unchecked it has no value.

Here is the working code.

<?php
if($input->post->changesettings) {
$deactivated = (isset($input->post->deactivated)) ? 1 : 0; $user->deactivated = $deactivated;
}
?>

<form method="POST" action="">
<input type="checkbox" name="deactivated" <?php if ($user['deactivated'] == 1) echo "checked='checked'"; ?>>
<input type="submit" name="changesettings" value="Change settings" class="bigbutton" />
</form>
