How to Get POST from multiple checkboxes

0 votes

I have 1 form in with multiple checkboxes in it (each with the code):

<input type="checkbox" name="check_list" value="<? echo $row['Report ID'] ?>">

Where $row['Report ID'] is a primary key in a database -so each value is different.

How would I be able to tell which checkboxes have been checked? (Maybe multiple)

This is for an inbox system and I have a button below that I want (when clicked) to delete all messages (ids of: $row['Report ID']) which have the checkbox's checked.

Hello @kartik,

Set the name in the form to check_list[] and you will be able to access all the checkboxes as an array($_POST['check_list'][]).

Here's example:

<form action="test.php" method="post">
    <input type="checkbox" name="check_list[]" value="value 1">
    <input type="checkbox" name="check_list[]" value="value 2">
    <input type="checkbox" name="check_list[]" value="value 3">
    <input type="checkbox" name="check_list[]" value="value 4">
    <input type="checkbox" name="check_list[]" value="value 5">
    <input type="submit" />
</form>
<?php
if(!empty($_POST['check_list'])) {
    foreach($_POST['check_list'] as $check) {
            echo $check; //echoes the value set in the HTML form for each checked checkbox.
                         //so, if I were to check 1, 3, and 5 it would echo value 1, value 3, value 5.
                         //in your case, it would echo whatever $row['Report ID'] is equivalent to.
    }
}
?>

Hope it works!!
Thank you!!
