Question

I have a simple example of check box’s which remember what has been selected after the form has been submitted and there is an error.

That part works great… but, I would like to post the resultant ‘checked’ boxes to my forms mail function.

What I have now only reports if its checked or unchecked I would prefer to have the checked box’s ‘value’ without the unchecked box even registering.

<?php

$CB_1 = 'unchecked';
$CB_2 = 'unchecked';
$CB_3 = 'unchecked';
$CB_4 = 'unchecked';
$CB_5 = 'unchecked';

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

if (isset($_POST['CB_1'])) {$CB_1 = $_POST['CB_1'];
if ($CB_1 == 'item_01') {$CB_1 = 'checked';}
}

if (isset($_POST['CB_2'])) {$CB_2 = $_POST['CB_2'];
if ($CB_2 == 'item_02') {$CB_2 = 'checked';}
}

if (isset($_POST['CB_3'])) {$CB_3 = $_POST['CB_3'];
if ($CB_3 == 'item_03') {$CB_3 = 'checked';}
}

if (isset($_POST['CB_4'])) {$CB_4 = $_POST['CB_4'];
if ($CB_4 == 'item_04') {$CB_4 = 'checked';}
}

if (isset($_POST['CB_5'])) {$CB_5 = $_POST['CB_5'];
if ($CB_5 == 'item_05') {$CB_5 = 'checked';}
}
}

if (isset($_POST['submit'])) {
$error  = "";

    if (!empty($_POST['email'])) {
    $email = $_POST['email'];

    if (!preg_match("/^[a-z0-9]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", $email)){ 
    $error .= "E-mail address not valid.";
    }

    } else {

    $error .= "E-mail address is required.";
    }

    if (empty($error)) {

    $from = 'From: '. @TEST .' <'. $email .'>';
    $to = "[e-mail]";
    $subject = "CHECKBOX TEST";
    $content = "

    checkbox selections: 
                        check box 01: $CB_1
                        check box 02: $CB_2
                        check box 03: $CB_3
                        check box 04: $CB_4
                        check box 05: $CB_5

    ";

    $success = mail($to,$subject,$content,$from);
    }
    }

?>



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

<?php if (!empty($error)) echo $error ?>

e-mail: <input type="text" name="email" value="<?php if (isset ($_POST {'email'})) { echo $_POST['email']; } ?>" />

<input type="checkbox" name="CB_1" value="item_01" <?PHP echo $CB_1; ?> /> Item 01

Answer 1

I found what I was looking for I suppose in the way of an array which I think ‘redelman431’ was trying to get me to do but it didn’t make any sense to me at the time.

I then stumbled onto another array by ‘David Bélanger’ that for some reason made more sense to me so I used it into my check box’s and it works fabulously.

the new problem is that I cant get the check box’s that have been checked to remember that if there is an error elsewhere on the page which is a disaster as my final form has a ton of them.

Any ideas?

<?php

    #   Default Vars
    $_group_01 = '';
    if(isset($group_01) === TRUE){
    #   Is Array ?
    if(is_array($group_01) === TRUE){
    #   Count
    $c = count($group_01);
    #   Loop
    for($i=0; $i < $c; $i++){
    $_group_01.= (isset($group_01[$i]) === TRUE ? $group_01[$i] : '').($i == ($c-1) ? '' : ($i == $c-2 ? ' and ' : ', '));
    }
    }
    }

if (isset($_POST['submit'])) {
$error  = "";

    if (!empty($_POST['email'])) {
    $email = $_POST['email'];

    if (!preg_match("/^[a-z0-9]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", $email)){ 
    $error .= "E-mail address not valid.";
    }

    } else {

    $error .= "E-mail address is required.";
    }

    if (empty($error)) {

    $from = 'From: '. TEST .' <'. $email .'>';
    $to = "[e-mail]";
    $subject = "CHECKBOX TEST";
    $content = "

checkbox selections: 

Items Checked: $_group_01

    ";

    $success = mail($to,$subject,$content,$from);
    }
    }

?>



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

<span style="color: red;"><?php if (!empty($error)) echo $error ?></span>

<br><br><br>

e-mail: <input type="text" name="email" value="<?php if (isset ($_POST {'email'})) { echo $_POST['email']; } ?>" />



<P>

<input type="checkbox" name="group_01[]" value="Item 01" 
<?php if(isset($_POST['group_01'])) { echo 'checked'; } ?> />Item 01

<input type="checkbox" name="group_01[]" value="Item 02" 
<?php if(isset($_POST['group_01'])) { echo 'checked'; } ?> />Item 02

<input type="checkbox" name="group_01[]" value="Item 03"

<input type="checkbox" name="group_01[]" value="Item 05"
