How to Retrieve Values from Multiple Checked Checkboxes in PHP?

Retrive Checked Values from Multiple Checkboxes in PHP

In PHP, capturing the values of multiple selected checkboxes in a single form poses no problem. To achieve this, follow these steps:

1. Set the Form's Name Attribute:

Assign a unique name attribute to the form itself, ensuring it ends with the [] suffix to indicate that it expects multiple values.

2. Set Checkbox Names and Values:

For each checkbox in the form, specify distinct names and values. In your provided code, the name attribute is set to check_list, and the values mirror the corresponding Report ID values from your database.

3. Retrieve Checked Values:

In the PHP script, access the checked values using the $_POST superglobal array. The checkbox values will be accessible as an array under the name specified in the form, in this case, $_POST['check_list'].

4. Process Checkbox Values:

Within a loop, iterate through the $_POST['check_list'] array, accessing each checked checkbox's value. In your scenario, these values represent the Report IDs of the messages to be deleted.

Example Code:

<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; // Echo the value for each checked checkbox (e.g., "value 1", "value 3", etc.).
        // Alternatively, perform your desired action on the checked values, such as deleting the relevant messages.
    }
}
?>
