What potential issues can arise when using radio inputs for tabs in PHP?

When using radio inputs for tabs in PHP, a potential issue that can arise is that only one radio input can be selected at a time, meaning that switching between tabs may cause the previously selected tab to become unselected. To solve this issue, you can use hidden input fields to store the selected tab value and keep track of the active tab. 

<?php
// Get the selected tab value from the hidden input field
$active_tab = isset($_POST['active_tab']) ? $_POST['active_tab'] : 'tab1';

// Check which tab is active and display its content
if ($active_tab == 'tab1') {
    echo 'Tab 1 content here';
} elseif ($active_tab == 'tab2') {
    echo 'Tab 2 content here';
}

// Hidden input field to store the selected tab value
echo '<input type="hidden" name="active_tab" value="' . $active_tab . '">';

// Radio inputs for switching between tabs
echo '<input type="radio" name="active_tab" value="tab1" ' . ($active_tab == 'tab1' ? 'checked' : '') . '>Tab 1';
echo '<input type="radio" name="active_tab" value="tab2" ' . ($active_tab == 'tab2' ? 'checked' : '') . '>Tab 2';
?>
